Thank you !
But I still dont understand, why this '&' is in the definition of windows
#define ON_COMMAND_EX(id, memberFxn)\
{ WM_COMMAND, CN_COMMAND, (WORD)id, (WORD)id, AfxSig_bw, \
(AFX_PMSG)(BOOL (AFX_MSG_CALL CCmdTarget::*) (UINT))&memberFxn },
and works when i use the original macro.

When I loaded up VC++ 6.0 today and went to my resource editor to edit a dialog box in my project, every time I double clicked on a part of it the MFC Class Wizard popped up and told me to add the dialog to a class. I am not using MFC, I have no idea how this setting got turned on and more importantly I don't know how to get rid of it so I can get on with my project. Someone please tell me how to de-activate this feature it is driving me nuts  Thanks!

Tools - Options - Compatibility - uncheck "Double-click in Dialog editor edits code (MFC only)".
By this way feature is deactivated completely. I really don't know what to do if you want to deactivate it only for non-MFC projects.

Hi all,
I developped a MDI application that shows a timetable for an appointment system. It basically show staff members and the appointments they are assigned. Each appointment is represented using a derived CWnd object. You get information on appointments by hovering on them using another CWnd derived object.
My problem is that I've got a lot of flicker when i'm dragging appointments or when I hovering on appointments. It really flicker when there's a lot of appointments showing up.
I tried implementing double-buffering but it didn't change anything, any idea?

Try to show the information by testing for a time lag
of say about 500 ms to 1 sec.
I think windows tooltips are also implemented in this manner

You can should draw at first to a memory dc and the draw to the screen.
Another solution is to use timers for redrawing.
My experience is also if it doesn´t work, may be there an conceptional mistake.
(Oversized solution)
IMHO: that each appointment is a CWnd seems to be no good idea. I would internally work with an array and access it via the screen coordinates. The output would be simple Retangles.

Hi,
The thing is that my controls are drawing themselves and that I already implemented a memory dc in the drawing code.
Could the problem be that my view is not actually drawing the controls, but just sending a WM_PAINT message to each of my derived CWnd controls ?
|
|

|
|
You´re right. You have understood the principle architecture of the Windows API.
My suggestion implies that the area would be drawn by the "containing" window.
Try it @ home. (B&B)

Thanks for the info, i'll give it a go.

By the way, did you know that 'flicker' is dutch 'slang' for a homosexual guy?
Imagine what MS-Word said a few years ago when I typed in a meeting report that one of our applications had a flicker-problem...
(I know this really belongs in the lounge-forum, but I couldn't resist, sorry).
Enjoy life, this is not a rehearsal !!!

Is there a way to find the minimum necessary size for the buffer argument of vsprintf before making the call?
rechi
|
|
|
|
|
sprintf works by calling a the low-level output function (_output) with a stream handle. that same output function handles all printf-style output (printf, sprintf, fprintf, etc). the output function simply outputs to a stream, which can grow as large as necessary.
so... to simulate it... run down the format string, parse it, add up the size of all the output specs. not easy.
-c
A conclusion is simply the place where someone got tired of thinking.

Use _vsnprintf and if it returns -1, your buffer is too small.
Tim Smith
I'm going to patent thought. I have yet to see any prior art.

If you have MFC installed (with VC6), the CString member "FormatV" (which is internally called by "Format"), does this sort of checking (i.e., runs through the format specifications and makes a "guess" at what size the buffer should be). The code for this function is in "YOUR_ROOT_MSDEV_DIRECTORY_HERE\vc98\mfc\src\strex.cpp"

I have an application where I want to find out the details of a DLL - version, internal name etc. if possible.
There is an original DLL which I need to check and replace with another of the same name.
Any ideas ?
Thanks.

You can read the version resource from them:
Here's a snippet from my code that does a very simple resource reading. (m_sArquivo has the fileName)
DWORD dwDummyHandle;
CString sArquivo(m_sArquivo.c_str());
DWORD dwSize = GetFileVersionInfoSize(sArquivo.LockBuffer(), &dwDummyHandle);
sArquivo.ReleaseBuffer();
if (dwSize == 0)
throw CWin32Error();
BYTE *lpBuffer = new BYTE[dwSize];
if (!GetFileVersionInfo(sArquivo.LockBuffer(), dwDummyHandle, dwSize, lpBuffer))
{
delete []lpBuffer;
throw CWin32Error();
}
VS_FIXEDFILEINFO *vInfo;
UINT uInfoSize;
if (!VerQueryValue(lpBuffer, _T("\\"), (LPVOID*)&vInfo, &uInfoSize))
{
delete []lpBuffer;
throw CWin32Error();
}
if (uInfoSize == 0)
{
delete []lpBuffer;
throw CWin32Error();
}
std::strstream out;
out << HIWORD(vInfo->dwFileVersionMS) << "."
<< LOWORD(vInfo->dwFileVersionMS) << "."
<< HIWORD(vInfo->dwFileVersionLS) << "."
<< LOWORD(vInfo->dwFileVersionLS) << std::ends;
delete []lpBuffer;
return out.str();

I create a project where I include a file.h in another folder in the same project.
when I used #include "myfile.h"
the compiler don't find the file.
How can I do for find it ?
Best Regards

or add the path ( relative path, not absolute ) to the "additional include directories" in the C++ tab of the project settings.
|
|
|
|

If the thumb compiler doesn´t find the file because he doesn´t find the file you must show him the file.

The workspace pane lists the following function incorrectly:
<br />
void Show(CRect rectTitle, LPCTSTR lpszTitleText, int xoffset = 0, LPRECT lpHoverRect = NULL, const LOGFONT* lpLogFont = NULL, COLORREF crTextClr = CLR_DEFAULT, COLORREF crBackClr = CLR_DEFAULT);<br />
It will say:
<br />
Show(CRect rectTitle, LPCTSTR lpszTitleText, int xoffset)<br />
When double-clicked, VS shows a messagebox saying it can't find the definition(implementation) of this function. (Well, duh...)
When it's changed (LPRECT changed to something like CRect*), the workspace pane will list the function as:
Show(CRect rectTitle, LPCTSTR lpszTitleText,int xoffset, CRect* lpHoverRect, const int LOGFONT)
Again, it goes awry, and this time it screws up bad... VERY bad. Making a
The only way to get a correct listing in the workspace pane is by removing the default-values....
This bug does not influence the compiling, fortunatly, but it makes debugging these botched functions a bit annoying. (select a different function, then scroll to the botched up one.)

Hello, everybody. I have an application in which I will have a control box with several data to fill in, several data to be updated, and some command buttons. I also like to add menu facilities.
If I used the mfc (exe) wizard application, either I create a single document or a control-box based application. So,
1. How do I include a control box without having a menu command to invoke it, I mean that the control box appears when I start the application.
2. How do I include menues facilities to the control-box based application?
I have been looking the online help, ans some manuals I have got without success.
Thank you very much,
