    htmlhelp API pressing the cancel button

    Hi Forum

    I have the following code ...

    Code:
            hHtmlHelp = HtmlHelp( hWndHandle,
                                  szHelpFileName,
                                  uiHelpCommand, 
                                  (DWORD)&link);
        if (hHtmlHelp==NULL) {
            MessageBox(hMainWnd,"Internal Help error"...... etc
    This API displays the Topics found and then when I press the Display after selecting the topic. displays the HTML help for that topic

    But
    If I press Cancel on the "Topic Found" dialog box, then my program enters this if Condition..
    I notice that even If I press CANCEL button, the 'hHtmlHelp' variable remains NULL.

    Question :
    How to detect if the user has pressed the cancel button instead of any other error ..

    Thanks in Advance
    Soft
