a chunk of your code would really help us to understand the problem.

Hummm, yes ! But that does exactly what you wanted, no ??? So where is the problem ??

why don't you just use WM_GETWINDOWTEXTLENGTH to get the length of the text in the edit field?

who can help me? I have a question. I want to insert a C Program into a MFC Project, I have tried to write "#ifdef __cplusplus extern C{ #endif" at the begin of the file and "ifdef __cplusplus } #endif" at the end. but it didn't work too. could you tell me a good method to solve it? Thank you very much.

Could you perhaps post what the compiler says?

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

1) The following goes in your header file or if use to surround the prototypes if you place them in one of your 'C++' files:
#ifdef __cplusplus
extern "C" {
#endif
#ifdef __cplusplus
}
#endif
2) Now just add the 'C' file to your work space the same way that you would add a 'C++' file. The compiler knows that is is a 'C' and will compile it as 'C'.
OOORRRR
3) You can just change the .c extension to .cpp and the file will be compiled ass 'C++' whith out having to modify any code at all.
Trust in the code Luke. Yea right!

hello
i have developed a application.when i build it in debug mode it works fine but when i build it in release mode it gets crashed. can anybody help me in this issue . what might be the problem
thanking you

Check your memory handling / array bounds.
In VC the Debug build generates safety pads for mem allocations / access, The release mode doesn't.
Check MSDN for more information. A search for 'Debug Build' will give you quite a few useful hints.

thanx for ur answer.
is it necessary to ship application in release build? if i have small exe then why not to ship it in debug build as it generates safety pads for mem allocations / access?
thanking you

Yes, you must ship the release-version. As far as I know it is
not allow to redistribute the debug-versions of the VC-DLLs.

You might not know this, but if you build release with pdb files (debug information) you can actually debug (with some limitations like optimized code etc.) your release build. This way you can at least find where in your program that fault occurs.

One classic reason for this is to define a ON_MESSAGE handler incorrectly. The prototype for the ON_MESSAGE hander is:
afx_msg long OnMyMessage(WPARAM wParam, LPARAM lParam);
But, if you define it like this:
afx_msg void OnMyMessage(WPARAM wParam, LPARAM lParam);
It will work fine in debug mode and crash in release mode. You get no warnings and it can be very, very hard to debug (because it works in debug mode). This one has got me before. It took about 2 days to figure it out.
Hope this helps...

I've got an one-dimensional array of an picture.
I know the dimensions of the pic.
int x_dim=348;
int y_dim=256;
unsigend char *mypic;
mypic = new unsinged char[x_dim*y_dim];
//now i get a pic from a cam that writes into mypic values betwenn 0(black)
and 255(white)
CBitmap pic;
How to create a CBitmap out of this
Thanks Heiko

At first create a HBITMAP -> MSDN "CreateBitmap"
with you can create a CBitmap
Try this @ home. (B&B)
|
|
|
|
|
A little bit of code would be helpful
I've tried many things without succes.
Heiko
|
|
|
|

Create a bitmap of the correct size and call SetBitmapBits(). See ::SetBitmapBits or CBitmap::SetBitmapBits in the doc.
onwards and upwards...
|
|
|
|
|
Or just pass all params in the CBitmap::CreateBitmap method...
onwards and upwards...
|
|
|
|
|
I've tried the way you say but it doesn't work
CBitmap pic;
pic.CreateBitmap( 348, 256, 1, 1, NULL);
pic.SetBitmapBits( 348*256,mypic );
why this doesn't work. The pic seemed to be "randomly"
I,ve written an routine to save the data as bitmap. This works fine. the bitmap looks right.
what is my failure?
Heiko
|
|
|
|
|
In your CreateBitmap call, shouldn't the nBitcount parameter be 8?
onwards and upwards...
|
|
|
|
|
Could be,
I will try tomorrow.
I've got an cam which makes about 15 pics per second and i want to display it. (so it is not possible to save it into a file first)
I think if tried the parameter 8 for bBitcount but i'm not sure.
Many thanks for now
I will ask again tomorrow in a new thread if it doesn't work

Hi,
I recently upgraded from VS 6.0 to VS.net 2002 (both enterprise edition), and now I get a error I can't seem to get rid of while compiling.
I have a pretty large array in my MFC project ( defined CString strScore[18][12][50]), in a seperate file, which I include where needed. The array is there to provide return data in a table lookup, (if I'm making sense now
On VS 6, I had to set compiler option /Zm300 to get the compile to go through, but this doesn't work now. I have tried /Zm2000 without result. I'm running on 512 MB RAM, with plenty of hard-drive space for the swap file, and I'm basically now sure how I'm supposed to get this to work.

At first I thought you were using more than 2GB but 18 * 12* 50 * 256 is only about 2 MB so I can't see what your problem is... What does the /Zm300 do?
