    Question Comparing EditBox data with a string.

    How would I gather the data that a user inputed into a editbox, and then compare it with a string?

    GetWindowText(Client_Edit_Message, Buffer, sizeof(Buffer));

    strcmp() enter buffer and other string

    You make your edit box. <assumed you did this>

    Client_Edit_Message = CreateWindowEx(WS_EX_STATICEDGE, "Edit", "", WS_CHILD | WS_VISIBLE | ES_MULTILINE, 1, 135, 400, 20, hWnd, NULL, g_hInst, 0);
    SendMessage(Client_Edit_Message, WM_SETFONT, (WPARAM)hDefaultFont, MAKELPARAM(FALSE, 0));


    then when user enters data in Client_Edit_Message box window you use GetWindowText(Client_Edit_Message, Buffer, sizeof(Buffer));

    you declared a Buffer[] to store your data from the window and the sizeof tell the functions howmuch to store in your Buffer[] variable.

    use strcmp() to compare the string you want to compare. ie test = strcmp( buffer , teststring );

    in winpr0c typicaly when a button has been pressed with case BN_CLICKED: message sent the getwindowtext is used so the proggie knows when valid data is there. ok?

    Well I tried this:

    Code:
    char Sgr[2]; 
    HWND hEdit;
     
    case WM_CREATE: {
    HFONT hfDefault;
    hEdit = CreateWindowEx(WS_EX_CLIENTEDGE, "EDIT", "", 
    WS_CHILD | WS_VISIBLE | WS_VSCROLL | ES_MULTILINE | ES_AUTOVSCROLL, 
    5, 170, 386, 75, hwnd, (HMENU)IDC_MAIN_EDIT, GetModuleHandle(NULL), NULL);
    SendMessage(hEdit, WM_SETFONT, (WPARAM)hfDefault, MAKELPARAM(FALSE, 0));
    if(hEdit == NULL) {
    MessageBox(hwnd, "Could not create edit box.", "Error", MB_OK | MB_ICONERROR);}
    else { }
    break; }
     
    case WM_LBUTTONDOWN: { 
    GetWindowText(hEdit, Sgr, sizeof(Sgr));
    if (lstrcmp(Sgr,_T("w1"))==0) {
    MessageBox(hwnd, "gOOD, iT WORKS!", "wOW!", MB_OK ); }
    break; }
    No errors, but it doesn't work. What did I do wrong?

    For one you are missing the switchcase() wich should belong to the winmain() or the proc.

    just started looking at it. that was the first i noticed let me look some more or get you an example.

    LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
    {
    switch(msg)
    {


    then your case here:

    you also need


    int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
    LPSTR lpCmdLine, int nCmdShow)
    {


    it is not a compleat prog.

    edit:
    You need to decide what type of window you want. You have the editbox. and reg the window.

    you need a message loop

    while(GetMessage(&Msg, NULL, 0, 0) > 0)
    {
    TranslateMessage(&Msg);
    DispatchMessage(&Msg);
    }
    return Msg.wParam;


    and the window procedure see above code.

    And the handle to the edit will have lost scope (as soon as the WN_CREATE was processed).


    Use a static HWND

    Or use

    GetWindowText( GetDlgItem(hwnd , IDC_MAIN_EDIT) ,.......
