It should not be possible for a hung application to clog up. Task-switching applications need to get window text so they can display the window title in the switcher window. FindWindow () needs to get window text in order to find a window. GetWindowText is a define of either GetWindowTextA or GetWindowTextW depending on your settings (because a TCHAR is either a char or wchart depending on the settings) So yeah the code compiles for you now, but it's still wrong. This member function causes the WM_GETTEXT message to be sent to the CWnd object. GetWindowText has a problem: Window text needs to be readily available without hanging. However, GetWindowText cannot retrieve the text of a control in another application, If the target window is owned by the current process, GetWindowText causes a WM. If the specified window is a control, the text of the control is copied. If the CWnd object is a control, the GetWindowText member function copies the text within the control instead of copying the caption. GetWindowText (user32) Copies the text of the specified window's title bar (if it has one) into a buffer. If the string is longer than the number of characters specified in nMaxCount, it is truncated.Ī CString object that is to receive the copied string of the window’s title.Ĭopies the CWnd caption title (if it has one) into the buffer pointed to by lpszStringBuf or into the destination string rString. The GetWindowText function copies the text of the specified windows title bar (if it has one) into a buffer. Specifies the maximum number of characters to be copied to the buffer. int y) DllImport(user32.dll) public static extern void GetWindowText(IntPtr hWnd, StringBuilder lpString. Points to the buffer that is to receive the copied string of the window’s title. It is 0 if CWnd has no caption or if the caption is empty. Specifies the length, in bytes, of the copied string, not including the terminating null character. Void GetWindowText( CString& rString ) const Int GetWindowText( LPTSTR lpszStringBuf, int nMaxCount ) const The following are 30 code examples of win32gui.GetWindowText().
