then what the hell is a calloc() call doing on a C++ code ?
C++ deprecates the use of C memory management such as malloc, calloc, realloc and free.
instead, you have to use new and delete, and you MUSTN'T miw the two ways together !!!

It may be that you want to much memory so the working set memory is fully used. There is a compiler option to tweak it, but i dont know which.

Can you show code, that is failing ?

Yes, But interesting to see, why he is facing problem.
Strange that people expect help without giving sufficient information.

Sometimes I wonder why you are a CP MVP.
I work with a large amount of legacy C code that use malloc/calloc/realloc/free I cannot, will not change that because it works and has been working for the last few years.
The question is valid, albeit not well "asked", in this forum.

There could be any nuber of reason why calloc() would fail. At the point of failure, what values are being passed to it?

If it returns NULL, it is a failure, like an out-of-memory or out-of-address-space condition. If it returns a non-NULL value, but things crash when you try to use it (i.e. it is truly invalid), then I would offer that the heap information used by calloc(...) is messed up,or you are going too far with the pointer returned.
Although, since calloc(...) has to actually touch the memory to initialize it to zero, it should crash within the call to calloc(...) if the memory it allocated is really invalid.
So, what do you mean by "returns bad pointer"?

Depends how good the programmer was. You may need no changes, you may need a lot. VC6 was a poor C++ implimentationm only coders who know the standard and coded to it would have no issues.

Are you talking about converting to VC8 with MFC, or converting to the CLR with Forms?
If you're talking about going to VC8 with MFC, it might take a couple of hours, depending on a) how large the code base is, and b) how talented the programmer doing the conversion is.
If you're talking about going to CLR/Forms, I think it would be best to just start from scratch.

Other controls, yes. Edit boxes, no. They are painful things, not well written

Hello,
Did anyone know how to get the current process id using an VS6 API function.
GetProcessId is VS7 compatible, i cannot use it.

Doesn't ::GetCurrentProcessId() help?

The Windows APIs are provided by the Windows OS, not VS.
A quick glance at the Platform SDK for the GetProcessId() API tells me it's for XPSP1 and above.
I would assume it may not be in the header files included with VS6 so maybe you need a newer
platform SDK.

Hi
all
I want to write resource dll in VC++, for this i want to copy resources from my old project to new resource dll, so please send me info of how to copy resources?
Thanks

This is true for VC6 - though I think it would be true for later versions.
Open your new project in the IDE.
Then use File | Open, set the Open As to Resource, and load the DLL.
Then drag the resource from the opened DLL to the resources in the New project.

I'm building a project under Visual Studio Express 2005. I have imported some old functions (contained in a .h and .cpp file) and am trying to add them to the project, but am having very little success. I am getting the following errors:
error LNK2028 unresolved token
error LNK2019 unresolved external symbol
But I have included the header file. I'm a little puzzled. Any help would be appreciated.
Windows with no internet connection is safe, but that's not what Windows was built for.

You need also to add the cpp file to your project.
