Status Bar
-
Hi, Hope someone can help me out here please. I'm trying to create a status bar in my app so I added the function:
// DoCreateStatusBar - creates a status bar and divides it into // the specified number of parts. // Returns the handle to the status bar. // hwndParent - parent window for the status bar. // nStatusID - child window identifier. // hinst - handle to the application instance. // nParts - number of parts into which to divide the status bar. HWND DoCreateStatusBar(HWND hwndParent, int nStatusID, HINSTANCE hinst, int nParts) { HWND hwndStatus; RECT rcClient; HLOCAL hloc; LPINT lpParts; int i, nWidth; // Ensure that the common control DLL is loaded. InitCommonControls(); // Create the status bar. hwndStatus = CreateWindowEx( 0, // no extended styles STATUSCLASSNAME, // name of status bar class (LPCTSTR) NULL, // no text when first created SBARS_SIZEGRIP | // includes a sizing grip WS_CHILD, // creates a child window 0, 0, 0, 0, // ignores size and position hwndParent, // handle to parent window (HMENU) nStatusID, // child window identifier hinst, // handle to application instance NULL); // no window creation data // Get the coordinates of the parent window's client area. GetClientRect(hwndParent, &rcClient); // Allocate an array for holding the right edge coordinates. hloc = LocalAlloc(LHND, sizeof(int) * nParts); lpParts = (LPINT)LocalLock(hloc); // Calculate the right edge coordinate for each part, and // copy the coordinates to the array. nWidth = rcClient.right / nParts; for (i = 0; i < nParts; i++) { lpParts[i] = nWidth; nWidth += nWidth; } // Tell the status bar to create the window parts. SendMessage(hwndStatus, SB_SETPARTS, (WPARAM) nParts, (LPARAM) lpParts); // Free the array, and return. LocalUnlock(hloc); LocalFree(hloc); return hwndStatus; }Which I got from MSDN. Then in my wndproc case: WM_CREATE I put in:statusbar = DoCreateStatusBar(hwnd, ID_STATUSBAR, hInst, 4);Everything compiles fine but unfortunately I don't get a status bar, is there some message I have to send it to make it display itself? -

If so then that is the reason.
