What am I missing to show a BMP correclty using the CStatic variable assigned to a Picture Control through MFC...
BITMAP test;
CBitmap m_bitmap;
HBITMAP m_hbitmap;
m_bitmap.LoadBitmap(IDB_BITMAP1);
m_bitmap.GetBitmap(&test);
m_hbitmap = m_bitmap.operator HBITMAP();
m_S1S2_Arrow.MoveWindow(40,50,test.bmWidth,test.bmHeight,1);
m_S1S2_Arrow.SetBitmap(m_hbitmap);
m_S1S2.Arrow.ShowWindow(1);
I would presume that the BMP would be loaded in and shown at this point, but I get nothing back. Any ideas would be great. Thanks so much.

I am not trying to draw a button, I am simply trying to load a bitmap on a screen to show them things.
Instead of having 20 variables each with only 1 BMP that it shows, I want to be able to have 3 or 4 and have them be able to switch to different BMPs to load up. However, when I do that and call the ShowWindow(1) function, nothing happens.

Can someone send me an invitation?

This is what I did to download a gif image from codeproject but ::recv will return after about a minute and return 0, can you help me out? I have not posted the whole code but everything goes fine except when it reaches ::recv
sockaddr_in server = {0};
pHostent = ::gethostbyname(_T("www.codeproject.com"));
server.sin_family = AF_INET;
server.sin_port = ::htons(80);
server.sin_addr = *(in_addr *) pHostent->h_addr;
nErrorTest = ::connect(socket, (SOCKADDR *) &server, sizeof(server));
::_stprintf(szSendData, _T("GET /info/stuff/codeproject_w2k_bg.gif\r\n"));
nErrorTest = ::send(socket, szSendData, ::lstrlen(szSendData), 0);
nErrorTest = ::recv(socket, szRecvData, sizeof(szRecvData), 0);

That is not a valid HTTP request. Try using the WinInet API or the MFC wrappers for it. They will keep you from having to deal with much of the protocol level coding.

My application needs to store a float number into to a byte array at the specific location. i.e. at byteArray[0] to byteArray[3] will store that float number. wrote :
byteArray[0] = ((byte*)&floatNumber)[0];
byteArray[1] = ((byte*)&floatNumber)[1];
byteArray[2] = ((byte*)&floatNumber)[2];
byteArray[3] = ((byte*)&floatNumber)[3];
but after write into a file and read back then
cout << (float) byteArray[0] << endl;
doesn't get the correct answer.
How to modify above code???

union FloatToCharArray {
float f;
char c[4];
};
then, you use it like this :
FloatToCharArray ftc.f = 4.12;
cout << "chars are : " << ftc.c[0] << " " << ftc.c[1] << " " << ftc.c[2] << " " << ftc.c[3];

I stored ftc.c[0] to byteArray[0];
ftc.c[1] to byteArray[1];
ftc.c[2] to byteArray[2];
ftc.c[3] to byteArray[3];
then output:
cout << (float)byteArray[0] << endl;
doesn't give the correct number.

of course, it can't work, you are converting only the first char into float, not the 4 chars...
use ftc.f (in my union) to retrieve the float...

This will work a bit better:
cout << *((float*)*byteArray[0]) << endl;
However, using the union described above, you could write much more clear code:
union FloatWrapper
{
float myFloat;
unsigned char myBytes[4];
};
FloatWrapper someValue;
someValue.myFloat = 1.23;
cout << someValue.myFloat << endl;
