I have several SplitterWnd with dialogbox-based FormView in my application.

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.

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.

make this variable global

How can I make this (test_26_tt1) variable global;

typedef struct <br />
{<br />
	unsigned short		data; <br />
        unsigned        4  :    count<br />
        unsigned        1  :    fault<br />
        unsigned        2  :    err  <br />
}TEST_26_TT1

// Form a union between the message structure and a buffer<br />
union<br />
{<br />
	TEST_26_TT1	message_data;<br />
	unsigned short	 buffer[32];<br />
}test_26_tt1;

If it was a float then I could do
// Globally declare the variable in just before the Main section of the code
float flt1;

extern float flt1; // This would allow global use in another unit of the program.

Or should type type of data be wrapped up in a class; as they are many.

what problem did you have when you used the same way as float?

No problem with the float;

Just do

extern float flt1;

in any units you want to use it.

My problem is with the union, how do I reference it in another unit?

extern <type=????> test_26_tt1;

I have lots of bit fields which I form into a buffer via the union (same memory, but two names).

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
