) and causing the program to hang for a long time, you can use the SendMessageTimeout(.) function instead. So, my conclusion is: try to use WM_GETTEXT message instead of GetWindowText.Ī little bit more Tips, if you are worried about being blocked when using SendMessage(hwnd, WM_GETTEXT. WM_GETTEXT message directly instead of calling If the target window is owned by another process and has a caption, GetWindowText retrieves the window caption text. However, GetWindowText cannot retrieve the text of a control in another. If the specified window is a control, the text of the control is copied.

So you can only get the control title (or content) by sending a WM_GETTEXT message to this control. The program lets you work with most windows containing text including Edit. When your program wants to get the title of a certain control of another process (such as the content of EDIT), calling GetWindowText function often gets empty, because when you call this function on the window of another process, the system directly returns CreateWindow (Ex) The content in the reserved space, but the title of the windows control does not exist in this space. GetWindowText lets you grab text from static system messages via drag-and-drop. For windows created with CreateWindow/CreateWindowEx, the system will store the window title in an address in the program space for windows controls, it is more common for the control to manage its title (or content) by itself. There are generally two ways to get the window title (or the content of the EDIT Control): 1.
