I make a program in window 95, In this environment it runs. Now I have took it to windows Millenium but when i run, it gives me a error "Debug Assertion faif, file: barstat.cpp, line 266". I have made a packet but it does not run.
thank in advances.

Simply look in barstat.cpp at line 266. The expression within ASSERT() (or similar) at that line evaluates to false running under ME, not in Windows95.
Or even easier: open in MS VC++, place somewhere before barstat.cpp 266, and trace the value of the expression.

Hi,
This is really annoying me.
char *buffer;
GetData(&buffer);
the plan here is that the GetData function will allocate buffer:-
void GetData( char ** ppBuf)
{
*ppBuf = new char [length];
strcpy (*ppBuf,"other data");
}
this appears to work. In fact, back in the original code block:-
printf(buffer);
works correctly.
But when i try and delete the allocated memory in the original code block:-
delete [] buffer;
I get a nasty debug "damage after normal block" type error. Both the main block and the called function exist within the same thread. I've traced through step by step in the debugger, and the address of the block of memory that is allocated by the new keyword is definately the very same block of memory that i am trying to delete.
Why does this occur????
thanks,
Jon

Does anyone knows where to find documentations (books or tutorials) about the way to work with the visual C++ environment ???
I mean :
- How to work with several sub-projects from different teams ?
- How to integrate and to work with external components such as DLLs without needs to copy files or header in my project ??
- How to use include/lib directories ???
- What is the detailled signification of the Project/Settings parameters ???
what I do not mean :
- How to use visual c++ to create dialog box or progress bars ... (and such things that is described in every VC++ books...)
Thanks,
Vince

Probably yes,
Just implement ::PreTranslateMessage in the main window class.

Mmmmm....
But ::PreTranslateMessage, will only work for Handles of windows of the same App, ... and my word instance belongs to another process space, is that correct ?

hi,
i've to reallocate a CString class member on runtime, i can't change the declaration in the parent class because it's a library but do it in the derived class.
The problem is that assigning to the CString a value the program exit with
HEAP[Sample1.exe]: Invalid Address specified to RtlFreeHeap( 5f0000, 5f4ccb08 ). Using .Empty() .ReleaseBuffer() and similar there's no errors, only assigning something.
It's a problem in the member allocation?

|

another thing, i use the debug version of the library with debug mode on.

I thinh you should post some code of what you are doing so we can better determine your problem.

i'm trying implementing a Cdocument derived class for the TX Text Control (www.textcontrol.com). the tx views needs this CTXDoc derived from CDocument. The component is created for an application with only a tx view and nothing else (this is very bad). In OnOpenDocument, OnNewDocument,etc it sets, deletes the contexts of the view,etc so if you call this overloaded funtions the program crash with diffent views. So i've substitued CTXDoc:: with CDocument:: and set the things for the tx init. But opening a created document, when SetPathName is called, there's an assignation to m_strPathName and m_strTitle of the CDocument and there's the Heap. I don't know how to solve, i've created the same variables in the derived class and rewritten SetAppName and GetTitle but in the others part of the application if there's a call to GetTitle it returns the CDocument variable that it's ""

I have a bit of a problem. I'm trying to write a plugin for Trillian Pro, but the example code is all C, and I've only had any luck modifying their example rather than writing my own dll from scratch.
I really want to use some C++ functionality (namely Ravi's Web Resource Provider)
Is there a simple way I can wrap up a C++ class into a .lib file so I can call it from C code?

I am afraid you cannot do that. C++ is a superset of C, so basically C is not aware of C++. Anyway, you can do the other way arround. From C++ call C functions. So my suggestion is write your application in C++ and use from there the C functions. Also make sure you add extern "C" when including C-header files.
Best regards,
Alexandru Savescu

Sadly that's not possible - I'm working with provided framework code that has to be C, so the main base of the code can't be modified to C++ else it won't work with the plugin API.
I was under the impression that it was possible to link c++ and C code together (initial experiments show that VisualC will happily link a C++ .lib file into a C project. It only complains when you try and access the code in the lib)

I think that your best bet will either to write COM object (which is a lot of work to use in C), or write a set of wrapper API functions that are exported from your DLL that will allow you to use your class from C.
These function will end up similar to the windows API, where you will create a function like CreateObject() that returns a handle to the new object pointer that you create.
Then when you call a member function you will pass in the handle to that object, and your DLL will translate the handle to the object and call the desired member function.
The reason that you cannot use a C++ class in C is because of the hidden this pointer that is included in all of the C++ class member functions. There are other ways to get around these problems, but I would really suggest one of my first to solutions.

There are plenty of articles here that discuss retrieving mail from POP3 servers (the normal kind of mail servers that most ISPs use) - just do a search for POP3 on this site
However retrieving mail from yahoo or hotmail is a lot more complex, as they don't provide standard protocols to access email on their servers

I've used MAPI to access hotmail through a telnet session. This is when I was just familiarizing myself with MAPI commands.

The GDI+ feature can be easily redistributed. GDI+ is standard on Windows XP. For Windows 98, Windows Me, Windows NT® 4.0, and Windows 2000, you can simply copy GdiPlus.DLL into your app's directory.
