Thanks! - Houdini Hide window instance in the system bar Gian16-Oct-02 2:23 Gian 16-Oct-02 2:23  Hi, i'm trying to do a program with a main dialog and a second that is opened or not from the first. The main dialog is modal and the second is modeless but when i create this last one there's another instance in the system bar of window and i want to hide it, is it possible? It's possible to make the 2 dialogs modeless?

I've noticed creating a modeless dialog from a MDI/SDI application the rectangle doesn't appear.

Tomasz Sowinski -- http://www.shooltz.com *** Purgamentum init, exit purgamentum *** Re: Hide window instance in the system bar Gian16-Oct-02 5:48 Gian 16-Oct-02 5:48  i've inserted cs.style &= ~WS_EX_APPWINDOW; cs.style |= WS_EX_TOOLWINDOW ; in the PreCreateWindow function of the dialog but with dlg->Create the program doesn't execute PreCreateWindow. Where i can put this code? The TOOLWINDOW option is set also with the dialog editor Re: Hide window instance in the system bar Tomasz Sowinski16-Oct-02 5:50 Tomasz Sowinski 16-Oct-02 5:50  You're trying to change window style while you need to modify *extended* style. Remove stuff from PreCreateWindow and add following line to OnInitDialog: ModifyStyleEx(WS_EX_APPWINDOW, WS_EX_TOOLWINDOW); Note that you can set WS_EX_TOOLWINDOW in dialog editor, but WS_EX_APPWINDOW is not accessible there (in VC6, at least).

As always thank you very much. Re: detect when the user leaves the mouse button over a button. Jon Hulatt16-Oct-02 2:16 Jon Hulatt 16-Oct-02 2:16  Do you mean when they let go of the mouse button on your control? If so, WM_LBUTTONUP Or do you mean when they move the pointer outside your button? Then use TrackMouseEvent & WM_MOUSELEAVE Or do you mean when the user moves the mouseout of your control while the mouse button is down? If so then set a flag when you get WM_LBUTTONDOWN and clear it when you get WM_LBUTTONUP, and also use TrackMouseEvent() and WM_MOUSELEAVE. Signature space for rent. Apply by email to....

Now I'd like to use this Activex in a VC++ project. Importing activex I can see only method but no events. How can I import this events and manage its? Thanks you Bye Re: Import Activex Event in a VC++ Project Roger Allen16-Oct-02 1:57 Roger Allen 16-Oct-02 1:57  If you have placed an activex control on a dialog or form, you can map the events using class wizard. Start classwizard Ctrl+W and goto the "ActiveX events" tab. From there you should be able to choose which you want to map.

CInternetSession::OpenURL memory leaks! Anonymous16-Oct-02 0:37 Anonymous 16-Oct-02 0:37  When use CInternetSession::OpenURL in a seperate thread,for example: CStdioFile* pFile=CInternetSession::OpenURL(...) If this thread for some reason is terminated suddenly,VC will detedct a memory leak: Detected memory leaks!<br /> Dumping objects -><br /> {202} normal block at 0x003478D8, 30 bytes long.<br /> Data: < /] > B0 00 2F 5D 0D 00 00 00 0D 00 00 00 01 00 00 00 and because OpenURL have not finished properly,so pFile is still NULL,so we cannot manage to dealocate the memeory by delete pFile. What should I do? Is it a bug in MFC?

Papa while (TRUE) Papa.WillLove ( Bebe ) ; Reason of suddenly terminating Anonymous16-Oct-02 1:02 Anonymous 16-Oct-02 1:02  Thanks for response. OpenURL will wait until received the response from server or time out.In a narrow band and slow connection,this may take some time.If the user is weary of waiting and click "Stop" button,I don't want to say "Hi! I'm waiting something from server,don't bother me! I'll stop until I can stop",I just want to stop the thread immediately.But in this way I don't know how to avoid the memory leak. Re: Reason of suddenly terminating Tom Welch16-Oct-02 1:50 Tom Welch 16-Oct-02 1:50  You have a couple of options for handling this correctly. 1. Let the thread finish it's work and clean up but make the application ignore the results and pretend like the thread is not running. 2. Use an asynchronous connection to the server which involves a bit more than a simple call to OpenURL, but will get you what you want. You can use this link to read more on ansync connections using CInternetSession[^] -- If it starts to make sense, you're in a cult.
