If a program you wrote can’t start becuase MSVCR*.dll is missing, then you forgot to ship the Visual C++ runtime…

Posted by jpluimers on 2012/08/30

Too often I see quesions like the one below on software that people distribute:

The Program can’t start becuase MSVCR100.dll is missing from your computer. Try reinstalling the program to fix this problem.

I am getting follwing error when i am trying to open Computer management in windows 7,the error is as follows ,

The Program can’t start becuase MSVCR100.dll is missing from your computer. Try reinstalling the program to fix this problem.

Where can i found this dll file, and help me to download and install.

The reason is that many programmers and companies still fail to ship the correct Visual C++ run-time.

Even for a one-off, you should need to get your installation set right. And writing stuff in a version of Visual C++ almost always means you need to ship the run-time for that particular version of Visual C++ with your application (though sometimes you can get away by putting the DLLs in the directory of your application, this is not recommended, as that way you won’t receive security updates).

User Marilyn O was so kind to sum up most of the download locations (I did a bit of post-editing, added all the non-“FamilyID” links, all naming differences are from the MS site):

I would install the Microsoft Visual C++ Redistributable dll that is needed for projects built with Visual Studio 2010.

Download the files below depending on your operating system version. […] Check in Programs and Features, do you show that you have installed Microsoft Visual C++ … Redistributable? If not, download from the links here.

Great session on how to prevent SQL Injection Myths and Fallacies

Posted by jpluimers on 2012/08/15

A few weeks ago, Bill Karwin did a must watch webinar on the prevention SQL Injection titled  “SQL Injection Myths and Fallacies“.

Bill Karwin (twitter, new blog, old blog, Amazon) is famous for much work in the SQL database community, including InterBase/Firebird, mySQL, Oracle and many more.

He also:

Anyway, his webinar is awesome. Be sure to get the slides, watch the replay, and read the questions follow up.

Watching it you’ll get a better understanding of defending against SQL injection.

A few very valuable points he made: Read the rest of this entry »

Hollerith and why we have digraphs in Pascal and trigraphs in C/C++ (nostalgia, Apple ][ plus)

Posted by jpluimers on 2012/07/04

Apple ][ plus keyboardSome nostalgia (:

In the mid 80s, when programming in UCSD Pascal and Turbo Pascal, I learned that Pascal has (. and .) digraphs that translate into [ and ], similar to the (* and *) digraphs that translate to { and }.

In fact I thought the English word was bigraph (as bi- is a prefix for twice, just like tri- is a prefix for thirce).
The digraphs are lexical alternatives (Pascal ISO  standard 7185:1990 paragraph 6.1.9 or Extended Pascal ISO standard 10260:1990 paragraph 6.1.11). There is even one more: the @ at-sign is a lexical alternative for the ^ caret.

Back then (I was in my teens, there was no internet yet and school library had nothing on programming) I thought these were because keyboards like those of the Apple ][ plus couldn’t emit [ and ], but I was wrong: it was in fact the Hollerith Card Code that could not represent these characters.

That limitation was because of the first Pascal implementation was done on a CDC 6000 series that used punched card readers/writers.  You could not punch arbitrary numbers of holes on each row (lace cards lacked structural strength) limiting the character codes you can represent.

They still work in the Delphi compiler for arrays and for comments (I just learned that various Pascal implementations use different rules of mixing digraph and normal comments (some even allow nesting)).

While I taught myself C and C++ just as I taught myself Pascal, somehow I never learned that they use lexical alternatives too. It was only recently that they do, both as trigraphs and as of C99 also as digraphs and that there is even a trigraph tool as part of the C++ personality of RAD Studio 2007.

There are reasons why Delphi is not C++ (via: Entropy Overload: One-liner RAII in Delphi)

Posted by jpluimers on 2012/06/06

There was a nice short discussion on Entropy Overload where Ivan Levanshew seemed to want to be Delphi way more C++ and Barry Kelly explains why Delphi isn’t C++.

Both Delphi and C++ are great languages, but both have weaknesses too. It is good that their individual strengths complement each other, and their weaknesses don’t crossover too much.

Ivan Levashew said…

It’s XE2 now, and there is still no proper RAII despite Delphi runtime already having all the required functionality for years. Variants copying and destruction is an example.

It’s a pity. Read the rest of this entry »
