hi,
here we declare char buffer as char buffer[ 1024 ] = { '\0' }..
How to release this?
|
|
|
|
|
It is released at the next }
ReturnType SomeClass::SomeFunction(SomeParams)
{
char buffer[1024] = {0};
return ReturnType::SomeValue;
} cheers,

I had a few of those. I think I rearranged some of the code to get it to work. But it was a long time ago. Use #error directive at the top of your source file that fails, move it downwards and see where it breaks. Then, try rearranging your code at that point.

try rebuild/clean the solution once before running

I have a vc++ application that has been showing odd characters on Japanese Windows installations.
It shows up an japanese katakana letter O (U + 30AA) instead of the micron character µ (mu)
i am using
sprintf(Buf, "%d µV", Values[i]);
My very simple task is to embed or force the "µ" symbol to remain as-is despite language settings.
Surely there is an easy method that I am missing somewhere!? Does anyone know an answer?
Much appreciation for any help.

Don't use ANSI strings, use UNICODE strings, ANSI strings will use the local Codepage for character conversions wich causes your problem.

Hi,
What windows message will be send to the application while closing the applcation[End Process] via task manager?
Thanks,
|
|
|
|
|
If you use the "End Task" button from the "Applications" tab the WM_CLOSE message is used. If you use the "End Process" button from the "Processes" tab it's closed forcefully and receives no notification.

For "End Task", system sends WM_CLOSE to the app window and wait for a specified time. After the time out if the window is not closed, "Application not responding" message will be shown, and the app is closed forcefully , if you select "End Now".

Hi,
Microsoft releases a list of what they call 'Breaking Changes' each time they release a new compiler.

Breaking Changes in the Visual C++ 2005 Compiler[^]
Breaking Changes in Visual C++ 2008[^]

When I am upgrading legacy VC6 applications... I would say that one of the most common problems that I find is within the STL. For example VC6 iterators could be compared to NULL which was non-compliant with the standards. You will now need to compare it to the container.end()
Hmmm I guess another issue I see alot is the forced conformance in for-loop scope. It seems alot of VC6 C++ software engineers would re-use variables outside of the loop scope. You can disable the conformance but I usually take the time to fix it.
Another common issue that I find within MFC projects... is that some of the MFC message handler function signatures have been changed from UINT to LRESULT.
Thats all I can really think of at the moment...
Best Wishes,

Hello every body !
Now I add some messages in the MainFrame:
1、#define WM_MSG_UPLOAD WM_USER+101
2、afx_msg LRESULT OnUploadMsg(WPARAM wParam,LPARAM lParam);
3、ON_MESSAGE(WM_MSG_UPLOAD,OnUploadMsg)
4、At last, I pose a MessageBox in the "OnUploadMsg" function.
In the Dll:
void MainMsg()
{
AfxGetMainWnd()->PostMessage(WM_CLOSE, 0, 0);
}
But in the debug mode, AfxGetMainWnd() also is NULL. how can I send the message from the dll space to the MainFrame?
thanks for your reply !
|
|
|
|
|
Are you sure that the window is created before MainMsg() in dll is being called? If not, m_pMainWnd member of theApp will be NULL.
|
|
|
|
|
First , thanks for you reply !
Of course,I start the main program first, the m_pMainWnd is impositioned be NULL.
when the MainFrame OnCreate,I load the DLL. and when I click some menu command,it load the dll'function ,so...
I means that how to design the Inform Mechanism, like dll inform to the MainFrame ? 
|
|
|
|
|
if no other way, try adding a function such as SetHwnd(HWND hWnd) in dll, to pass window handle. From dll, use this handle to call ::SendMessage(hwnd, .. ..) 
|
|
|
|
|
I see, thank you very much!

Is your DLL an extension DLL and does it call AfxInitExtensionModule() in DLLMain (or whatever you've called it)?
It sounds like you're building a regular DLL and have created your own CWinApp derived object in the DLL. As the main window isn't created by the DLL m_pMainWindow is zero and AfxGetMainWnd hasn't got a lot to return.
Have a quick gawp at this.[^] It's got some more info about extenstion DLLs.
Cheers,
Ash

Hi,
I was trying in vain to do some background coloring for a bitmap I was using a lot of people at the site gave
me valueble help however noting seemed to worked
fustrated I decided to look at the bitmap in core before and after BitBlt
I issued GetBit hoping to look at memory at the before and after value of the BITMAP.bmBits member
but the value returned was nulls before and after each BitBlt call
thanks in advance

This should work for you:
CDC cdcimage;
cdcimage.CreateCompatibleDC(&cdcwindow);
COLORREF clrFill = RGB(128, 128, 128);
CBrush brush;
brush.CreateSolidBrush(clrFill);
CBrush *pOldBrush = cdcimage.SelectObject(&brush);
CBitmap *oldbit = cdcimage.SelectObject(&m_bitmap);
COLORREF clr = cdcimage.GetPixel(0, 0);
cdcimage.ExtFloodFill(0, 0, clr, FLOODFILLSURFACE);
cdcimage.SelectObject(oldbit);
cdcimage.SelectObject(pOldBrush);

I also tried GetBitmapbits what I saw was 3 bytes of white color
e.g. FF FF FF followed by a null 00
I am in the US time 12:30 pm
I'll try the code later on tonite
Thanks so much

It seem to fill part of the background with 128
When I dumped the bitmap GetBitmapBits I noticed the following pattern for 52 bytes there is the following seq FF FF FF 00
ExtFloodfill chages the seq to 80 80 80 00
after which the bitmap has a different shade of white FE FE FE to the naked eye this would seem like white
However when using BitBlt or ExtFloddFill to chage the background it will stop at he FE FE FE
I wonder I convert the Color to MonoChrome that I should only get 2 patterns white FF FF FF and black 00 00 00
then maybe by using SetBkColor and SetTextColor I can change the arrow and background to what I want

Well, that's what you want isn't it? And that's what the code I supplied does. Could you maybe post your entire function, because I think you might be doing some other things causing problems.

I appreciate it but what I meant was for 52 bytes the pattern was solid white e.g. FF FF FF after wards I noticed FE FE FE meaning to the naked eye it looked like the same color
your function worked great .. filling what was at location 0,0 until it encountered a different color pattern e.g. FE FE FE
I going to try to dump the entire bitmap and post it and my code (with OLE rtn that displays the bitmap) when I get home from work
thankx so much
