An http requests of the client to the server may contain a request header and a request body (later only for POST requests). The response of the server to the client -almost- always consists of a response header and a response body.
What do you wanna get?

Are you on a server? Are requests being sent to your IP?
Then this is pretty easy: extract the request header from the begining of the data.

Hi,
I am loading a bmp file through LoadImage() and accessing the image data through GetBitmapBits().
Now i am saving the data as follows:
BITMAPFILEHEADER hdr;
LPBITMAPINFOHEADER lpbi;
CFile file;
if( !file.Open( the_filename, CFile::modeWrite|CFile::modeCreate) )
return FALSE;
lpbi = (LPBITMAPINFOHEADER)m_pFirstBuffer ;
lpbi->biBitCount=24;
int nColors = 1 << 24;
if(nColors> 256) nColors=0;
lpbi->biClrUsed=0;
lpbi->biSize=40;
lpbi->biHeight =(DWORD)bmp.bmHeight;
lpbi->biWidth=(DWORD)bmp.bmWidth ;
lpbi->biXPelsPerMeter =lpbi->biYPelsPerMeter =0;
lpbi->biClrImportant =0;
lpbi->biPlanes =1;
lpbi->biCompression =0;
lpbi->biSizeImage = bmp.bmHeight *bmp.bmWidthBytes ;
// Fill in the fields of the file header
hdr.bfType = ((WORD) ('M' << 8) | 'B'); // is always "BM"
hdr.bfSize = (DWORD) (sizeof(BITMAPFILEHEADER) + lpbi->biSize + lpbi->biClrUsed* sizeof(RGBQUAD) + lpbi->biSizeImage);
hdr.bfReserved1 = 0;
hdr.bfReserved2 = 0;
if (lpbi->biBitCount > 0 && lpbi->biBitCount <= 8)
{
hdr.bfOffBits = (DWORD)(sizeof(hdr) + lpbi->biSize +nColors * sizeof(RGBQUAD));
}
else
{
unsigned long cmapsize = 0;
switch (lpbi->biBitCount) {
case 16:
case 32:
if (lpbi->biCompression == BI_BITFIELDS) {
cmapsize = 3*sizeof(DWORD);
}
break;
case 24:
cmapsize = lpbi->biClrUsed*sizeof(RGBQUAD);
break;
default:
// no colormap
break;
}
hdr.bfOffBits = (DWORD)(sizeof(hdr) + lpbi->biSize + cmapsize);
}
// Write the file header
file.Write( &hdr, sizeof(hdr) );
// Write the DIB header and the bits
file.Write( lpbi, lpbi->biSize );
file.Write( m_pFirstBuffer, bmp.bmHeight *bmp.bmWidthBytes );
file.Close ();
Now i could open the saved file in Windows Paint application but if i call LoadImage() with that file name as parameter it returns NULL. GetLastError() is zero.
Could anyone tell me where i am wrong?

Hi Neha,
Actually , While saving the BITMAP u converted it into Device independent Bitmap.and LoadImage API cannot load DIB's , it can load only icon, cursor, animated cursor, or bitmap or OEM Bitmaps.
If u want to display this Bitmap, then u have to read the file by your own code ,get the BMP data in a buffer prepare headers, and u can use
APIs like DrawDibDraw to draw ur image

I think you got confussed.
I am using GetBitmapBits() it returns device dependent bitmap. In LoadImage() i am setting LOADFROMFILE. this will returns us the HBITMAP.I mean to say the value returned from LoadImage() ie HBITMAP is NULL.

// Write the DIB header and the bits
file.Write( lpbi, lpbi->biSize );
check these above line of ur code
In ur Submitted code , u have created this DIB header,
Which states that the BMP u created is DIB,and let me know if u the file extension is .bmp then that means u have created an DIB image , thats why LoadImage fails.
Check few artilces for .bmp files , u can see these Windows supported Picture files are Device independent.
Even if u used the GetBitmapBits , but while saving u converted it into DIB

My file extension is .DIB not .bmp.
It works for some images but for some images it doesn't.
|
|
|
|
|
Well the extension doe'snt matter,
what i think is that u r saving it as DIB
and even ur extension says it is a DIB  ....
try to read it as a DIB image may be it will solve ur issue!!

Yes, I am wrong.
Could you please tell me how to save the DDB data?
I need to use the DDB format because DIB takes DWORD.

In VC, on the Window Menu, there are a couple of options, Next Window, Previous Window, and Close All. I have been trying to figure out how they do that, and have search through hundreds of project files and came to this conclution. Almost No One uses the Close All function.
Welp, I must be dumb, but I can't figure out how they do that. Anyone here know how?

ummmmm by iterating thru the doc-template docs and views?
"there is no spoon"
biz stuff about me

I know that, I have tried fifty different things, I just keep getting the code wrong. I was currious if any one knew of an example project, that had it, or just new the code for it.

try GetFirstDocTemplatePosition() and all the associated functions for the template itteration
then GetFirstDocPosition() for the actual docs in a particular template
go from there
its really only 10 lines of code

 i want to draw an irregular window with mfc. the requirements list below:
1. the irregular window based on SDI or MDI or Dialog;
2. the irregular window appears automatically when i start the program;
3. the shape of the window is according to a inputted picture. some color wish to be ignored, for example: white, then the part of the picture i wanted becomes irregular;
4. the edge of the irregular window is smooth, i mean that there is no unexpected color around the window;
5. if i moved the window, there is no rectangle made up with broken line around the window.
Could anyone show me how to draw it? i wish a details method. if possible, could anyone give the resource codes?
thanks a lot
