Hi, Cpallini
I am trying to find out some clue here... I am confused now... What's wrong with my code or proj? And the STL support headers are all included and employeed its namespace too.

You should post the errors and (as Richard pointed out) the relevant code for getting better help

We can't just guess based on your description, we need facts code and error messages, Watson!

Oh... I am trying to catch the error. But I found it is uncertain and not repeatable.. 
Try to find more and report later ...

What about the code & error message?

In order to use the CInterfaceClass in another DLL, as a base class, you need to export this class first.

Really? I've make the interface class as one interface class with all functions of pure virtual property. It says it is an abstract class only. It seems not required to export it with the DLL's derived class. Right?

hi
what's the best method to get the currently active child frame window/ currently active view/ or document?
consider we're in one of children of main frame or their children and have no access to any window.
|
|
|
|
|
Here is what use in my MDI applications:
CMDIFrameWnd* pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
CMDIChildWnd* pChild = (CMDIChildWnd*)pFrame->GetActiveFrame();
CMyView* pView = (CMyView*)pChild->GetActiveView();
CMyDoc* pDoc = (CMyDoc*)pChild->GetActiveDocument();
|
|
|
|
|
oh thanks!
i was mistaking:
CFrameWnd *pFrameWnd = GetTopLevelFrame();
CView *pView = pFrameWnd->GetActiveView();
and i wondered why it returned NULL. now i changed it into:
Ct2View *AcToolCtrl::pr_getActiveView()
{
CView *pView = GetTopLevelFrame()->GetActiveFrame()->GetActiveView();
ASSERT_KINDOF(Ct2View, pView);
return (Ct2View *)pView;
}
and it worked.

Looks like something wrong is happen in a library, resulting in a multiple deletion of a block, of in an access to an already delete piece of memory.
Probably, upon a previous message handling, you deleted something the library still needs.

The only thing I can see from your information is that HeapFree fails (what was the text of the message ???) when invoked by a number of library function that are in consequence to the OnSmtpTimer invocation, that -at certain point- assign and destroy a CMemFile that is no more there.
What does all that to happen, I don't know.
I don't see your code, your screen, your mind!
I can only suggest to investigate about what was OnSmtpTimer trying to assign and verify if (and where) something else destroyed it before. That's what debuggers are for.
Does "http://dofev.de" and "10022*Socket Error" means something to you?
Probably a CMemFile is attempted to be deleted after that point (look like after a socket connection failed). But ... it seems it is no more there. Probably it is something related a previous iteration of the message loop (so it is not on the stack anymore ...)

Hi
i got function name and argument type from UnDecorateSymbolName() method using vc++ MAP file. But i want how to argument names with using VC++ MAP file?
any idea please?

Have you looked in a .map file to see what it contains? If you had you'd have found the following things:
- They're simple text files
- They contain the addresses of things assigned by the linker and (usually) the size of those things
- They don't contain (unless I completely missed it a couple of weeks ago when I last had to look in one) names of function parameters.
Information about parameter names is not generally available to the linker as the compiler sorts out the mapping of argument names to position on the stack/register assignment, the linker doesn't have to know it.
I've no idea what you need this information for but remember C++ is a compiled language that, unlike Java, doesn't support any sort of type reflection or introspection. If you want to find out names of parameters your best bet is to look in something that's generated for a debugger - e.g. a .pdb file under VC++ and use something like the Debug Information Access API (which I've only glanced at, it might be rubbish, I can't comment).
Cheers,
Ash

I want to use wxWidgets to develop UI,and use it in MFC.
Thank you gurus.

My current project needs to be supported by IKnownFolder.
But I've never programmed with this kind of interfaces.
So anyone could help?
I'll really appreciate it if you could give some links or codes on what files should be introduced in and how and the initialization codes.
Thanks in advance.

Hi
I am using UnDecorateSymbolName() method get function name and argument data type. but i want actual argument variable name? i try this code like
void ExtractCppSymbol(char *szDecoratedName)
{
char szFunc[512];
if ( UnDecorateSymbolName(szDecoratedName, szFunc, 512, UNDNAME_COMPLETE > 0 ))
{
cout<

As far as I know the argument names aren't in the decorated name, so there is NO way to extract them.

i am using input mangled data from VC++ MAP file. This MAP file contains all details.
i parse MAP file and pass to UnDecorateSymbolName() method.
OR
how to pass input for argument name with mangle data?
|
|
|
|
|
The function and method names are decorated accordingly to the used calling convention, anyway what you can extract from a decorated name is, at most, the type of the formal parameters of a function (e.g. int, char *, struct MyStruct &, etc.), but not the name used in the source code.
