Thanks for everyone's help!! Smile | :)

For anyone else who's having the same problem, one last thing you must do before this solution will work is to add a variable in you main dialog class so that when it loads your control it will use the subclass for the control instead of the original.

Details: using the class wizard generate a new variable with your subclass type, click the control check box (VS 2003 .Net) so that DDX_Control will update the value.

You can also follow Chris Maunder's great tutorial on subclassing controls:

Straight from MSDN:

WCHAR wszUserName[256];
char *sString = "XYZ";

MultiByteToWideChar(CP_ACP, 
                    0, 
                    sString, 
                    strlen(sString) + 1, 
                    wszUserName,   
                    sizeof(wszUserName) / sizeof(wszUserName[0]));

Hi,
I have several SplitterWnd with dialogbox-based FormView in my application. For a good layout i need the size in pixel of the dialogboxes (generated with the ressourceeditor) as early as possible to arrange the splitter windows.
Please help me! Smile | :)

How many CSplitterWnd controls are there? Is the view in each pane derived from CFormView?

What are you wanting the size of the panes to be based upon?

I have up to 11 SplitterWnd in my application, the panes in four of them are derived from CFormView.

So does this mean that you have 22 panes (I'm assuming that there are two panes per splitter window)?

Use to convert a specific File to a Bitmap

Greets,

i need a idea, how i can convert a sepcific (graphic) file to a bitmap witch is based in memory.
Reason is: i can't write out a bitmap-file, and load it after writting, cause the file information have to be secure. After the bitmap staying in memory i can load, show, and destroy it. I think so?

I know the bitmap file format, and i have the informations from the specific file to fill bitmap-structure-components. So what i don't know is: witch interface can i use to open and get the specific file informations, how i can load the packed bitmap, after i fill the structure, into the memory, and how i can display this packet bitmap.

thanks for every answer Smile | :)

a BMP file is simply a BITMAPFILEHEADER followed by a DIB. so, just skip the BITMAPFILEHEADER and call StretchDIBits to display the DIB.

CFile and std::string

ns5-Aug-04 2:56

5-Aug-04 2:56

I get this error:

'__thiscall CFile::CFile(const char *,unsigned int)' : cannot convert parameter 1 from 'const char *(void) const' to 'const char *'

when I try to do :

CFile filePort(m_outputFileName[0].c_str, CFile::modeRead);

m_outputFileName[0] is a std::string.

Will I have to strcpy m_outputFileName[0] into a char temp[256] and put that into CFile?
I'm not sure how to make the std::string behave for the CFile. Is there a simpler way?

Thanks,
sb

Added:

I get the same error if I do:

char file1[256];

strncpy ( file1, m_outputFileName[0].c_str, 256);

Hi Guys,

How Can I convert a CString to a T_String.
My T_String is a typedef defined as follows.

typedef std::wstring T_String;//wstring,co's my project is unicode defined.

Thanks......

Just curious....

Why are you doing that? CString has already unicode support.

5-Aug-04 4:43

since CString (when UNICODE is defined) and std::wstring both are defined as an array of wchar, you could safely do:

CString sOther = _T("This is a string");
T_String s = (LPCTSTR)sOther;

Try CopyFile(), MoveFile(), SHFileOperation(), or the CFile class.
