I have a function inside a DLL that acts as a hook procedure. it has an __stdcall attribute. When i tried to retrieve the function pointer via another exe with GetProcAddress it always fails, and it only works after i remove the __stdcall attribute. How can i retrieve the function pointer of this callback function properly?
Is there any difference in the way of retriving function pointer of regular function and callback function?
*** code ***
this is the hookproc function:
LRESULT CALLBACK HookProc(int nCode, WPARAM w, LPARAM l)
{
return CallNextHookEx(NULL, nCode, w, l);
}
and this is how i call it in another exe:
FARPROC HookProc = NULL;
HookProc = GetProcAddress(HookDLL, "HookProc");
*** end of code ***
thank you very much.

goto www.dependencywalker.com [^]and download the tool - use it to see how your function is being exported.
You can use a .DEF file to control how your function is being exported (see MSDN for details). You can also use the /EXPORT linker switch if you are using visual-c

thank you, i'll try it =)

I also STRONGLY reocmmend you call your HookProc something ELSE. That name is too common and might also get you into trouble with other linkage and project dependencies later.

It is SHIFT+ENTER in MS Word

Is your RichEditCtrl a control in a CDialog or a CRichEditView? As a control you will need to use PreTranslateMessage() to trap the shift+enter keys (VK_SHIFT, VK_RETURN) or the dialog will close via the default button (usually CDialog::OnOK()).
<code>BOOL CSampleControl::PreTranslateMessage(LPMSG lpmsg)
{
BOOL bHandleNow = FALSE;
switch (lpmsg->message)
{
case WM_KEYDOWN:
switch (lpmsg->wParam)
{
case VK_UP:
case VK_DOWN:
case VK_LEFT:
case VK_RIGHT:
bHandleNow = TRUE;
break;
}
if (bHandleNow)
OnKeyDown(lpmsg->wParam, LOWORD(lpmsg
->lParam), HIWORD(lpmsg->lParam));
break;
}
return bHandleNow;
}
</code> - Source: MSDN Help Documentation.In a CRichEditView class the RichEditCtrl will respond to a SHIFT+VK_RETURN keyboard event and insert a soft carriage return (\par). If you hit the enter key (VK_RETURN event), it inserts a hard return (\par\par). This is, if your document class serializes as richtext.
CRichEditDoc::m_bRTF = TRUE; If you are serializing as text then you can insert a newline character with
GetRichEditCtrl().ReplaceSel("\n");In both cases of serialization the RichEditCtrl responds to the (SHIFT+ENTER)keyboard event the same.
Post a litle more info on what you are trying to do.

Hi All,
I have been using CString for years and was very much comfortable with it.
Now i am using STL's string.
while debugging i am not able to get the value of a string variable.it shows the address and not the value(string::c_str).
if it was a CString variable, just by putting the variable in the Quick Watch i was able to see its contents.
How do i get the value of a string variable during debugging ?
Thanks in advance

It almost sounds like you need to add an entry to your autoexp.dat file. You'd see the same thing with CString if it weren't for that file.

Hi David,,
I'd be very interested to know what you exactely mean with your answer. I thought there was no (easy) way to see the content of stl strings while debugging... What is autoexp.dat ?

I don't use STL, so that may very well be the case.

It's a file located in the C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin folder. There is a good description at the top of it.

Use
<br />
dlg.m_ofn.lpstrFile=TEXT("DefaultFile.xxx");<br />
before DoModal()
Have a nice code day

I don't know, it is strange! 
A good thing could be add the flag OFN_FILEMUSTEXIST here:
CFileDialog dlg(TRUE,"bmp",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,"Only BMP (*.bmp)|*.bmp|");
So you are sure that the file exist.
And I don't like very much
...,"Only BMP (*.bmp)|*.bmp|"
I prefere
...,"Only BMP (*.bmp)|*.bmp||"
Let me know
Have a nice code day
