I have an application in VC++ which needs to execute a function provided to it (function name entered in a text box) from a COM DLL (file name provided in another text box). I have seen code for loading a Win32 library using LoadLibrary and GetProcAddress. How can this be done for a COM DLL file (created in Visual Basic 6.0)? Is there...

I would like to move fairly complex types from the managed to native world and visa versa. Currently this is being done by creating multidimensional safearrays, which has the advantage that marshalling is done for you, but means we end up with rather complex jagged arrays to get our heads around. I have tried to put some structs into S...

I'm currently working on a large and old C++ application that has had many developers before me. There is a lot of "dead code" in the project, classes and functions that aren't used by anyone anymore.

Visual C++ seemed to be a good solution but after having the GUI part done I couldn't integrate the plain C++ code. Does someone have any experience with that? I get 'unresolved externals' error. Apperantly the .cpp file...

By referring Joel's Article Some people are under the misconception that Unicode is simply a 16-bit code where each character takes 16 bits and therefore there are 65,536 possible characters. This is not, actually, correct. After reading the whole article, my point is that, if someone told you, his text is in unicode, yo...

Both ComponentA and ComponentB ...

I usually put a breakpoint to the last line of the code so that the I can inspect the console when one of the tests fails: n = UnitTest::RunAllTests(); if ( n != 0 ) { // place breakpoint here return n; } return n; But I have to reinsert it each time I check-out the c...
We are in the process of creating active-x controls used within our application. Since Microsoft stopped supporting classic Visual Basic, is it wise to use Visual Basic to develop the Active X control or the latest VC++/ATL/MFC libraries provide more feature where we can create controls faster by leaving Visual Basic flexibility? We w...
This is C4055 Warning message. 'conversion' : from data pointer 'type1' to function pointer 'type2' A data pointer is cast (possibly incorrectly) to a function pointer. This is a level 1 warning under /Za and a level 4 warning under /Ze. How do we resolve this warning?(By correct way, not a trick) Edit: This is a code...

I tried http://code.google.com/p/feed-reader-lib but holy cow, talk about difficult to build. It has a nightmare of dependencies on Xerces and Xalan, both of which seem to be choking under the new VisualStudio 2010 C++ compiler. I've wasted hours trying to build this thing which is a shame. Does anyone have anything a little easier to hi...
