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.

MS quote (http://www.microsoft.com/ddk) : As of September 30, 2002, the Microsoft® Windows® 2000 DDK, the Microsoft Windows 98 DDK, and the Microsoft Windows NT® 4.0 DDK will no longer be available for purchase or download on this site.

Set my window to wndTopMost. HOWTO?

BlackSmith7-Sep-02 3:08

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 Unsure | :~

. Very funky...

Any ideas why this occurs? Any at all?

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

Another Caret in the CEdit

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.

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

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);

How to set the width to CChildFrame in MDI

Tomas6-Sep-02 20:43

Tomas

6-Sep-02 20:43

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.

In the pdwEffect return value for your Drop Event handler, return DROPEFFECT_COPY and this will indicate to the source to make a copy of the data rather than moving the data. It is actually up to the source as to what it wants to do though.
