Ok, after doing some research on a related topic, I stumbled across what you were talking about. You're asking about the subnet mask.
I don't know how you get it. But, as I stated earlier you can send 255.255.255.255 as a broadcast for all subnets. If your IP address was 192.168.1.22 and your subnet mask was 255.255.255.0 then sending a broadcast message with IP address 192.168.1.255 would work also. Thus, that becomes a broadcast message for that subnet only.
The procedure I read said negate OR the subnet mask with your IP address to get that value.
e.g. ip |= ~mask to get broadcast address.

I have to supply documentation for the user of the app (not docs for the code). Things like features and instructions and troubleshooting etc. I'd like to make this like the help system we see that pops up with tabs for index, search, contents etc. Can you please point me to links, sample code etc on how to do this?
Thanks,

In the Solution Explorer window, right-click on your project and select Properties. In the dialog box, unfold the Linker folder, click on Input. Then add your .lib file(s) in Additional Dependencies.

My window (CWnd derived) is created by <font color=blue>CWnd</font>::CreateEx(WS_EX_TOPMOST,..., WS_POPUP, hwndParent).
hwndParent has WS_CHILD style, for it's the only way I could find to create my window without taskbar icon (My wnd is a tooltip-like).
I also used:
<font color=blue>CWnd</font>::SetWindowPos(&wndTopMost,0,0,0,0,SWP_NOSIZE | SWP_NOMOVE);
My window couldn't top the taskbar  . Very funky...
Any ideas why this occurs? Any at all?

In a previous post, I sugested setting the desktop as the parent of your pop-up with Cwnd::SetParent. Didn't this work? (just curious)

use this code
::SetWindowPos (m_hWnd , m_Options_AlwaysOnTop ? HWND_TOPMOST :HWND_NOTOPMOST,
0, 0, 0, 0,
SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE) ;

I write following code In Win98
CClientDC dc(this);
CBitmap bmpTemp;
BOOl bRes = bmpTemp.CreateCompatibleBitmap(&dc, 4000, 2000);
ASSERT(bRes != 0); // It failed in Win98, But in Win2k it's OK !!!
When I changed it to:
"BOOl bRes = bmpTemp.CreateCompatibleBitmap(&dc, 4000, 1000);"
It's OK
I want to know:
What's biggest size bitmap in Win98 can create ??
It's me, code_cold

Windows 95/98/Me: The created bitmap cannot exceed 16MB in size.

You are right
Then, How can I create a more than 16M bitmap
I need this bitmap to buffer a bitmap file
It's me, code_cold

Does the CreateBitmap has the same limitation as CreateCompatibleBitmap(No more than 16M size bitmap create) ??

Whether it is possible to change the caret in CEdit with a vertical line to another (for example: blinking or solid rectangle)

Yes in such a way will change the caret, but before the first click the mouse in the CEdit. After that the kind of the caret comes back to a vertical line.

How send some bitmap with winsock?
|
|
|

You can send data over a socket. Bitmap is a data type.

BITMAP bitmap;<br />
char *szBuff;<br />
int nBmpSize;<br />
<br />
::GetObject(HBITMAP, sizeof(BITMAP), &bitmap);<br />
<br />
nBmpSize = bitmap.bmWidth * bitmap.bmHeight;<br />
szBuff = new char[nBmpSize];
//You can copy any other data the will help you to create a bitmap(its size)
memcpy((void*)szBuff), bitmap.bmBits, nBmpSize);<br />
<br />
send(theSocket, lpBuff, sizeof(lpBuff),...);
//Use the received buffer to create a bitmap on the client/server side.
CBitmap bmp;<br />
bmp.create(...); <br />
bmp.SetBitmapBits(<font color=green></font>);
Email me if this works well, or for any other help!

I think it is easier to:
BITMAP bitmap;
char *szBuff;
int nBmpSize;
::GetObject(HBITMAP, sizeof(BITMAP), &bitmap);
nBmpSize = sizeof(BITMAP) + bitmap.bmWidth * bitmap.bmHeight;
szBuff = new char[nBmpSize];
//You can copy any other data the will help you to create a bitmap(its size)
memcpy((void*)szBuff), &bitmap, sizeof(bitmap)); // we will ignore 'bmBits' pointer
memcpy((void*)szBuff), bitmap.bmBits, nBmpSize);
send(...)
// now Create can use receive buffer that hold information on the bitmap
CBitmap bmp;
char* szBuff = (received buffer...)
BITMAP bitmap;
memcpy(&bitmap, szBuff, sizeof(bitmap));
bitmap.bmBits = szBuffer+sizeof(bitmap);
bmp.CreateBitmapIndirect(&bitmap);

Hello.
I have a MDI App. and I would like to create some views with the same width that the App. Frame.
This do not work because the View is bigger than the MDI Frame.
BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs)
{
RECT rect;
SystemParametersInfo(SPI_GETWORKAREA,0,&rect,0);
cs.x = cs.y = 0;
cs.cx = rect.right;
return CMDIChildWnd::PreCreateWindow(cs);
}
Anybody knows how to make the MDI frame and view the same width that the App frame?.
Only the width, the heigth must be default.
Thanks in anticipation.
Tomás

Do not use SystemParametersInfo to get the size of the parent frame. Instead get a handle to the mainframe (AfxGetMainWnd) and get the client area rectangle.
