hSrcBitmap is just use LoadBitmap from resource and stored in
a global member so that it can be shared by some windows.

If hSrcBitmap is not a DIBSection:
hSrcBitmap has to be the same format as the screen or the SelectBitmap will fail.
What format is hSrcBitmap? 8bpp? 24bpp?

The origin bitmap of hSrcBitmap is 24bpp.

Can you reproduce the problem consistently and debug it, like error checking
all the GDI cal return values?

Hi all,
I am getting an error C2022: '65279' : too big for character at the line in bold below, What should I change here? This code works if I use wsprintfW and wszBuffer is WCHAR however I need this for multibyte and must use "_T" not "L"
Any advise?
Thanks,
Jayjay

I don't see a bold line. Error C2022 in the documentation says, "The octal number following a backslash (\) in a character or string constant is too big to represent a character". So I am guess that you are trying to assign a number greater than 255 for a char variable.

Hi Saurabh,
It is this line
_T("\xfeff<?xml version=\"1.0\" encoding=\"UTF-16\" ?>\n")
Thanks,

The first character is \xfeff which is 65279. This value cannot be stored in a char variable. I think you can split it into two characters for ANSI chars (\xfe\xff) and single char for wide-chars.

But:
Keep in mind how values are stored.On an Intel Machine: \xfeff should be reversed when broken up as: \xff\xfe.

Hello
I have a strange behavior with a program I've made
I've first made a dialog box with an OpenGL display
Everything was working ok
Then I added a button in my dialog box then transfer my OpenGL calls in it (subclass from CButton)
The OpenGL drawing work ok on the button, but the timer on my calling dialog box freeze when I'm using the OpenGL functions
The timer resume normally when I close the dialog box
- The OpenGL call is the same as it was when it was directly on the dialog box
- When I deactivate the OpenGL calls, my timer work ok
Do anyone have an idea off what is happening?
Thank you

Hello again!
Using MFC, I am trying to implement an EDIT BOX and to print the content of it into a file.
I have associated a variable to the EDIT BOX, and that is CString varName.
When writing this variable into a log file, LOG.Write (varName, <not yet sure what length> ); , i get the result:
- for input: Shpid3r => S<square>h<square>p<square>i<square>d<square>3<square>r<square>.
I think that this is because using UNICODE character set, and every character in the CString is using 2 bytes, whilst using it into the Write() method, converts the string byte-by-byte.
Setting to use ANSI, creates an error (not finding a header file)... anyway my application should support unicode character set, even if logging will not meet unicode characters.
How should I do in order to get a proper logging?
Thank you!

You may:
- Convert your string to an ANSI one before writing it to the log (check out the T2A macro [^]).
or just use (a usually annoying feature of C++ )
- wofstream object to print the string (no need to convert it) to the log file.

Find out what colum is selected, and sort accordingly. Just ALWAYS make sure that you have more than one thing to sort!!

I do'nt know what grid are you using : anyway I think in most cases you will
have some sort of callback of the type :
int onCompareTwoRows(int row1,int row2,int columnIndex){
}
where you define your comparision mechanism that would then be called by the sorting algo, in the grid implementation you are importing.
based on the column selected (columnIndex) you can just apply the comprarision on the 5 desired rows only :
int onCompareTwoRows(int row1,int row2,int columnIndex){
if(columnIndex==theColumnIwant){
if(row1 && row2 are in the 5 chosen rows set){
return -1,0 or 1 accrding to context..
}
}
else
return 0;

I'm trying to override the global new operator:
void* __cdecl ::operator new(size_t nSize)
{
...
}
It is called for almost all cases. However in case of std::string allocation it does not work. The internal allocator of the std::string object still calls the default (CRT) global new allocator.
Any idea why?
Thanks,
Abyss

Maybe the STL authors want to control the allocation process just as you are trying to do.

Not sure, because for std::vector my new operator is called. And in some cases for the std::string too. In the particular case the given std::string calls my new operator, however my delete operator is not called. This of course is toxic, because the default CRT delete tries to release my pointer and the application crashes. My delete operator is defined as:
void __cdecl ::operator delete(void* ptr)
{
...
}
Not sure what is wrong here...
Thanks,
Abyss

You do know you have the ultimate documentation, don't you?
