I don’t do P/Invoke often, and somehow I have trouble remembering the value of CharSet to pass with DllImport.
In short, pass CharSet.Auto unless you P/Invoke a function that is specific to CharSet.Ansi or CharSet.Unicode. The default is CharSet.Ansi, which you usually don’t want:
when Char or String data is part of the equation, set the CharSet property to CharSet.Auto. This causes the CLR to use the appropriate character set based on the host OS. If you don’t explicitly set the CharSet property, then its default is CharSet.Ansi. This default is unfortunate because it negatively affects the performance of text parameter marshaling for interop calls made on Windows 2000, Windows XP, and Windows NT®.
The only time you should explicitly select a CharSet value of CharSet.Ansi or CharSet.Unicode, rather than going with CharSet.Auto, is when you are explicitly naming an exported function that is specific to one or the other of the two flavors of Win32 OS. An example of this is the ReadDirectoryChangesW API function, which exists only in Windows NT-based operating systems and supports Unicode only; in this case you should use CharSet.Unicode explicitly.

When using Entity Framework 4, your transofmrations (model to classes, DB to model, etc) are performed by T4 Text Templates.
Those templates are executed all over the place (when saving your project, building your project, changing your model, etc).
Since anyone can insert a T4 Text Template into Visual Studio, and those are scripts, it is a potential vulnerability.
The default Visual Studio behaviour is to show you a dialog like this:
[Security Warning]
Running this text template can potentially harm your computer. Do not run it if you
obtain if rtom an untrusted source.
Click OK. to run the template.
Click Cancel top stop the process.
[X] Do not show this message again
[OK] [Cancel]
Some blogs mention Just click OK and feel free to check “do not show this message again.”
I’m not sure I want that: it would indicate I always trust T4 Text Templates, even the ones added in the future (T4 Text Templates are executable content, malicious software could find it’s way into your development environment; anyone remember the virus that hooked itself into the run-time library sources of a development system so it would spread through anything compiled on that system?).
But I also don’t want to click OK on that dialog.
It would be so nice if the dialog:
- Showed which template is about to be executed
- Allowed me to skip only for that particular template
Anyone better thoughts on this?

Zack Owens wrote a nice article comparing various loop constructs.
Summary:
If the semantics are the same, it does not matter if you use foreach, for, while or do while: they all have equal speed.
So: choose the loop construct that best fits the problem you are trying to solve.

Often you work with projects not having the latest stuff.
Sometimes that is a good thing: latest stuff is not always best 
In this case, the client had Office 2003, and needed to do some Excel automation from .NET.
The development systems however had Office 2007 on it, so importing Excel defaults to the Office 2007 Primary Interop Assembly: Office version 12 in stead of 11. Read the rest of this entry »

Earlier this week, Red Gate announced that the new Reflector version 7 would cost USD 35, as of March 2011, and the current free version 6.6 will expire on May 30th, 2011.
That caused a lot of stir, on their forum, twitter, reddit and a lot of other places. Even an old thread at StackOverflow got a new boost. It seems Red Gate did not read Social media judo: How to turn a fight into a brand-building moment.
Here is a summary of the past, present and future of things happening around reflector, including some workarounds and alternative products.
First a bit of history.

If you want to do Windows Phone 7 development, then get this book: Programming Windows Phone 7 by Charles Petzod.
The eBook and source code are free:
This book is a gift from the Windows Phone 7 team at Microsoft to the programming community, and I am proud to have been a part of it. Within the pages that follow, I show you the basics of writing applications for Windows Phone 7 using the C# programming language with the Silverlight and XNA 2D frameworks.
Yes, Programming Windows Phone 7 is truly a free download, but for those readers who still love paper—as I certainly do—this book will also be available (for sale)
In addition to C# and VB.NET, you can also do this in Delphi Prism.
Cool times ahead, because now there are 4 major competitors (in no particular order):
- iPhone
- Android
- Windows Phone 7
- Symbian
I left out the competitors of the past, as they soon will be deprecated.

When you write .NET 4 software, you want to deploy it to your clients, so they need to install the .NET Framework 4.
On fully patched Windows Server 2003 x86 installations, the (optional) Windows Update for Microsoft .NET Framework 4 for Windows Server 2003 x86 (KB982671) usually results in this error:
Installation Failure
Error Code: 0×80246002
Try to install the update again, or request help from one of the following resources.
It fails during download, so it does not even reach the install phase.
Don’t loose too much time resolving this: The usual solution for 0×80246002 as described in KB958056 does not work.
The systems affected don’t have anti-virus or similar software installed, so disabling those won’t work: there is nothing to disable.
What does work is the suggestion a bit lower in the 0×80246002 update fails search results Read the rest of this entry »

When you do some maintenance on old projects, you sometimes bump into things you have completely forgotten about.
This time it is in Visual Studio 2005, with a WPF app, and messages about App.xml.
Since there are few threads covering this problem, so I’m not sure how many people bump into this.
I know that the problem does not limit itself to C#; I have seen people in VB.NET and Delphi.net bump into this as well.
This problem is not limited to Visual Studio 2005, some people also have it in Visual Studio 2010.
Some people also have it with other objects than App.xaml (like Windows1.xaml, etc).
If you get this error, the solution is simple:
- perform a “Clean Solution”,
- then run your app again.
This trick has worked for me every time I bumped into it. Read the rest of this entry »

Scott Dorman udpated his macro to change the target framework version for all projects in a solution to Visual Studio 2010 and published the new macro on CodeProject.
His new macro now supports these target frameworks:
Notes:
- The links are to the download pages of the frameworks; look for “Standalone version” or “Full installer” for non-bootstrap download.
(version 1.1 can be downloaded here, but is not supported in VS2010)
- The “Client Profile” versions are stripped down versions of their “Full” counterpart.

I always tend to recompile assemblies when something changes they depend upon.
But now I’m even more careful after reading Fabulous Adventures In Coding : Putting a base in the middle.
Especially his checklist is important.
When you use a newer version of an assembly you depend on:
(1) at the very least test your derived types with the new base type — your derived types are relying on the mechanisms of the base types; when a mechanism changes, you have to re-test the code which relies upon that mechanism.
(2) if there was a breaking change, recompile, re-test and re-ship the derived type. And
(3) you might be surprised by what is a breaking change; adding a new override can potentially be a breaking change in some rare cases.

The Microsoft patterns & practices Developer Center released the Microsoft Enterprise Library 5.0 last week.
This version of the Enterprise Library has a ton of new features, and now has full support for .NET 4.0 and Visual Studio 2010.
Next to using it from C#/VB.NET, I’m looking forward to see how well this can be used from the upcoming Delphi Prism 2011 release (scheduled to be released on May 15th).
Lots of stuff to experiment with

If you have a TechNet or MSDN account, you can download the SharePoint, Office, Visio and Project 2010 RTM builds.
Downloads have become available on April 23rd.
The SharePoint designer is available from the Microsoft Download centre as William Conrwill describes at CodeJedi.NET : SharePoint, Office, Visio and Project 2010 RTM are now available on MSDN.
If you have SA, then as of today (April 27), you can get your volume licenses as well.
William describes more dates in his post Office, SharePoint, Project and Visio 2010 have made RTM!

I usually pick a fresh VM for installing an RTM build, but if you have loads of stuff on your (physical) machine, upgrading RC to RTM can be a real time saver.
Stack Overflow has a nice question Upgrading Visual Studio 2010 RC to RTM answered by Danny Thorpe (yes, two links: blog / wikipedia).
The order is really imporant, so lets repeat that here:
- Uninstall all the VS 2010 parts
- Uninstall the .NET Framework Multitarget package.
- Reboot
- Uninstall the .NET Framework client package
- Reboot

Every major release of software will bring great new stuff, but the price of upgrading from a previous version is that some stuff will break.
.NET 4.0 brings a lot of nice stuff as well, but there are a few things that break.
There is a nice Breaking changes in .NET 4.0 – Stack Overflow article on this.
The article is now a community wiki, and refers to these pages:
Since the article is a community wiki, expect it to be updated over time.
I wonder what these changes will bring (and break) in the upcoming Delphi Prism release (the datasheet is out now, the product should be out before the end of may).

Google published an interesting graph generated from their internal data based on their indexed web pages.
A quick summary of popular encodings based on the graph:
- Unicode – almost 50% and rapidly rising
- ASCII – 20% and falling
- Western European* – 20% and falling
- Rest – 10% and falling
Conclusion: if you do something with the web, make sure you support Unicode.
When you are using Delphi, and need help with transitioning to Unicode: contact me.
–jeroen
* Western European encodings: Windows-1252, ISO-8859-1 and ISO-8859-15.
Reference: Official Google Blog: Unicode nearing 50% of the web.
Edit: 20100212T1500
Some people mentioned (either in the comments or otherwise) that a some sites pretend they emit Unicode, but in fact they don’t.
This doesn’t relieve you from making sure you support Unicode: Don’t pretend you support Unicode, but do it properly!
Examples of bad support for Unicode are not limited to the visible web, but also applications talking to the web, and to webservices (one of my own experiences is explained in StUF – receiving data from a provider where UTF-8 is in fact ISO-8859: it shows an example where a vendor does Unicode support really wrong).
So: when you support Unicode, support it properly.

Today, I bumped into something utterly strange: requests replayed through Fiddler 2 to a locally running ASP.NET Development Server on Vista using localhost URLs did not give a connection.
I use ASP.NET from both C# and Delphi Prism. Most of my development work is on Windows XP (see notes below) but I test on many platforms.
Moving one of the projects from XP to Vista, and testing with Fiddler, I found that when using Fiddler 2:
This form of URL fails on Vista, but works on XP: http://localhost:49703
This form of URL works both on Vista, and XP: http://127.0.0.1:49703
So on Vista – contrary to XP – localhost requests from Fiddler were in fact being sent to the external network adapter on Vista, and the 127.0.0.1 requests to the internal network adapter.
Since the ASP.NET Development Server is bound only to the internal network adapter, external requests don’t work (boy, I wish they did, it would make some of my debugging so much easier!).

Somehow, CodeCentral managed to not only delete my uploaded CodeRage 4 session materials (the videos are fine!), but also newer uploads with other submissions.
Since I’m in crush mode to get the BASTA! and DelphiLive 2009 Germany sessions done, and all Embarcadero sites having to do with their membership server perform like a dead horse, I have temporary moved the downloads, and corrected my earlier post on the downloads.
I have notified Embarcadero of the problems, so I’m pretty sure they are being addressed on their side as well.
Edit 20090919: Embarcadero indicated that between 20090913 and 20090914 there has been a database restore on CodeCentral. Some entries therefore have been permanently lost.
When I get back from the conferences, and CodeCentral is more responsive, I’ll retry uploading it there, and correct the posts.
In the mean time, be sure not to save shortcuts to the current locations, as they are bound to change.
The are the new download locations can all be found in my xs4all temporary CodeRage 4 2009 download folder.

You can find them in the CodeRage 4 sessions overview.
In order to download them from that overview, NOTE: To access this session replay, you must be logged into EDN. you can login or sign-up (which is free).
To make it easier to find all the relevant downloads, below is an overview of my sessions and their links.
Let me know what you use it for, I’m always interested!

* Christine_Ellis has set the topic to: Session Room 2 – “Practical XML in
Delphi“
[8:35:37 AM] <Peter_Wolf> a lot of memory = usually 10 timer more than the size of XML file bytes
[8:36:27 AM] <Peter_Wolf> … the size of XML file in bytes
[8:39:14 AM] <Jeroen_Pluimers> @Peter: that totally depends on what you use to read that XML. The MSXML and Internet Explorer are notorous memory hogs. But .NET is much more efficient on memory usage.
[8:40:15 AM] <Peter_Wolf> i ment MSXML which is default for most users
[8:41:17 AM] <Jeroen_Pluimers> @Peter: yup, that’s why I mentioned that as the first one. Most of the Win32 users will use MSXML, because that is the default for Win32.
[8:43:45 AM] * Jeroen_Pluimers warns: be carefull where you press ESC in IE: it can unload your chat window.
[8:47:29 AM] <Scott_Hollows> my brain hurts
[8:48:57 AM] <Jeroen_Pluimers> Scott: let me know later on if I can make it more clear to you.

[8:58:56 AM] <Jeroen_Pluimers> My VIP room died.
[9:00:08 AM] <AbsaLootly> … you have to hate it when that happens…
[9:01:46 AM] <Ryan_Ford> What alternatives for MSXML are there for WIN32
[9:02:22 AM] <Peter_Wolf> it also takes forever to open really big XML files wh MSXML

My CodeRage 4 session materials are available for download:
CodeRage 4 is a free, virtual conference on Embarcadero technologies with a lot of Delphi sessions.
It is held from September 8 till 11, 2009, i.e. while I write this
If you want to watch sessions live, be sure to register through LiveMeeting (the technology they use for making this all happen).
Let me know if you download, and what you are using the sample code for.

I just finished recording my CodeRage 4 sessions:
- Practical XML in Delphi
- Reliable Communication between Applications with Delphi and ActiveMQ
- Using Unicode and Other Encodings in your Programs
CodeRage 4 is a free, virtual conference on Embarcadero technologies with a lot of Delphi sessions.
It is held from September 8 till 11, 2009, i.e. next week
If you want to watch sessions live, be sure to register through LiveMeeting (the technology they use for making this all happen).
This week, I found some time do migrate all the sample projects to the release versions of Delphi Win32 2010 and Delphi Prism 2010.
Delphi Win32 2010 works like a charm: it is much faster and has a much smaller footprint than any other Galileo based IDE.
In fact, it feels almost as fast as the pre-Galileo based IDE’s.
With the added benefit that all the new features make me much more productive, not the least because it has not yet crashed on me this week once.
Crashing has been a frequent thing on me since Delphi 4 (maybe I should not even mention that number ), for most IDE’s at least a couple of times a week, so this is good.
Delphi Prism 2010 works really nice too, it is rock solid, and the language as some great features not found in other .NET languages.
But it still needs a tiny bit more polishing on the Visual Studio IDE Integration part.
There are a few things not as smoothly integrated as I’m used to in C# and VB .NET (for instance when adding assembly references; C# and VB.NET allow you to do that from multiple places in the IDE; Delphi Prism from only one).
I know it is nitpicking (the same holds for the Team Foundation System integration in the Visual Studio IDE: ever tried to add files or folders? There is only one icon that allows you to do it. Ever tried to move files or folders around? No way you can drag & drop, in fact you can move only 1 file or folder at a time, and then the folder tree leaves you at the target).
The Embarcadero folks have worked hard on developer productivity in the Delphi Win32 2010 IDE.
(Did I mention the F6 key? It is an awesome way of directly jumping into configuration dialogs a zillion levels deep.
Did I mention the Ctrl-D key? It instantly reformats your source code to your formatting settings).
So maybe it is now time to put some of that effort into the Prism side as well.
Back to my CodeRage sessions: the recordings are done, they will soon become available as downloads together with the samples/slides.
Keep watching

I do a lot of .NET work; most in C#, but also some in Delphi Prism (which like C#, VB.NET and other languages integrate in the Visual Studio Shell).
Both Visual Studio and the .NET Framework SDK include a nifty tool called XSD.EXE.
XSD.EXE allows you you to generate the code for wrapper classes from your XSD or other schema definition file, both for regular classes (that you can use for XML Serialization) as well as for typed dataset classes.
You need to specify the Oxygene language to generate Delphi Prism code.
A sample batch-file is here:
xsd /classes /language:Oxygene /namespace:xokumClasses xokum.xsd
rename xokum.pas xokumClasses.pas
xsd /dataset /language:Oxygene /namespace:XokumDataset xokum.xsd
rename xokum.pas xokumDataset.pas

I just found out that in my updates to TFS 2008 Folder Comparison Filter for both C# and Delphi projects somehow some backslashes (\) were missing.
Oops, sorry
These backslashes are important when excluding directories: if omitted, TFS thinks you want to exclude a filename in stead of a directory name (see Folder Comparison Filters).
It might be due to the HTML pasting issue that I explained in Including formatted sourcecode in WordPress.
Anyway, here is the correct one that has the backslashes at the right places:
!*.pdb;!*.obj;!*.dll;!*.exe;!*.res;!*.resources;!*.cache;!*.ilk;!*.ncb;!obj\;!objd\;!bin\;!lib\;!*.local;!*.identcache;!*.dcu;!__history\;!*.dsk;!*.~*;!*.stat;!*.drc;!*.map;!*.csproj.user;!*.vbproj.user;!*.csproj.webinfo;!*.vbproj.webinfo;!*.suo;!*.bpl;!*.dcp;!*.log;!*.lck
(Note these all should be on one line when pasting them).

Last month I wrote about the TFS 2008 Folder Comparison Filter for both C# and Delphi projects; here is an update:
If you enable the generation of MAP files during compilation, you might not want to include them in your search filter.
Also, the .suo, .user and .webinfo extensions were missing (for an explanation of Visual Studio file extensions, see here and here), so then the search filter becomes this:
!*.pdb;!*.obj;!*.dll;!*.exe;!*.res;!*.resources;!*.cache;!*.ilk;!*.ncb;!obj\;!objd\;!bin\;!lib\;!*.local;!*.identcache;!*.dcu;!__history;!*.dsk;!*.~*;!*.stat;!*.drc;!*.map;!*.csproj.user;!*.vbproj.user;!*.csproj.webinfo;!*.vbproj.webinfo;!*.suo
Have fun with it!
