    GetWindowText doesn't return the text

    I have made a textbox and there is text in it, but when I use GetWindowText(...) to get the text it returns a uni code string full on nonsence stuff.

    Here is the string it returns:

    UMVt8U ;


    No matter the text I put it always returns that. Why and how can I get the real text?

    And if I use SendMessage(hwnd_of_textbox, WM_GETTEXT, (WPARAM)10, (LPARAM)text)

    it gives and "sorry application had to close" error.

    Are you certain that your HWND value is valid?

    I made the textbox my self so yes, cause the text will change if I send a change message.

    maybe post the part of the code where you have to grab the text..
    * PC: Intel Core 2 DUO E6550 @ 2.33 GHz with 2 GB RAM: Archlinux-i686 with xfce4.
    * Laptop: Intel Core 2 DUO T6600 @ 2.20 GHz with 4 GB RAM: Archlinux-x86-64 with xfce4.

    Code:
                	GetWindowText(recvbox, text, 10);
                	//SendMessage(recvbox, WM_GETTEXT, (WPARAM)10, (LPARAM)text);  //Gives an error
                	SendMessage(recvbox, WM_SETTEXT, NULL, (LPARAM)text);
    There is the code. I put the text from the recvbox back into as a test, wich still gives that messed up string.

    Is text large enough to hold 10 characters? What does GetWindowText return? If it's zero, what does GetLastError return afterwards?

    LPSTR text;

    That's your problem. You need to declare it as:
    Code:
    TCHAR text[10];

    bithub, it would be more compatible if it was:
    Code:
    char text[10];
    Instead of:
    Code:
    TCHAR text[10];

    Or if you really want it in a LPSTR format, just do this:
    Code:
    char textT[10];
    GetWindowText(recvbox, textT, 10);
    LPSTR text = textT;


    BTW: I tried compiling it the way you had it,
    ad I got errors. How come when you did it, it did it.

    Nothing. I just noticed that you clicked the "Post Reply" button twice. The reason I thought you had dial-up is because some times people tend to push it twice thinking it didn't go though the first time because the page didn't load fast enough.

    I wish I had DSL.
    (My speed is only 63kbps.)
