Graphics g(pDC->GetSafeHDC()); // pDC is a pointer of CDC

Welcome
For your information:
While populating the items in the list, the GUI thread is blocked. That's why it is not updated by default. So if it takes much time for populating the list, the application will go to "not responding" state. In order to avoid that case you can use a worker thread to populate the list.

There is no need to call UpdateData() when populating a listbox. You either need to update the listbox window after each insertion, or do this work in a separate thread so the main thread is not blocked. The former is obviously easier.

Hi,
How to find wheather a dilaog window is opened or not programatically.
Thanks
|
|
|
|
|
I'd try retrieving something from the window, such as DialogName.GetDC(), and then see if the function returns nothing, or something like that, although there should be a better way of checking.

You can use IsWindow, IsWindowVisible, etc

Hi,
I have an option in my application tray menu to display a dialog.When i have used the IsWindowVisible also that particular dalog is displaying as many times the option in the tray menu is selected.If the dialog is already opened it should not open again.I have used the following code.But it doesn't work.How can i go further.
CDialog dlg;
if(dlg.IsWindowVisible())
{
dlg.ShowWindow(SW_HIDE);
}
Thanks

How do you show the dialog? DoModal?
Can you show me the code snippet of the menu option handling?
- NS -
|
|
|
|
|
void CMainFrame::OnSettings()
{
// TODO: Add your command handler code here
CSettings dlg;
if(!(dlg.IsWindowVisible()))
{
dlg.DoModal();
}
}
When i right click on my application's tray icon a tray menu will display.My tray menu have one of the option called "Settings".When click on "settings" the settings dialog( class name:CSettings) will display.But my problem is when i click on the settings n times,then n number Settings dilaog is opening.What i required is,if dilaog is already opened it should not open again.How can i do this.
Thanks.

The problem is that you are using the DoModal and the dlg is local in OnSettings(). In this case I will suggest a simple solution.
1. Make the CSettings dlg as class member, CSettings m_dlgSettings.
2. Change the code as,
void CMainFrame::OnSettings() <br />
{<br />
if( IsWindow( m_dlgSettings.m_hWnd )) return;<br />
m_dlgSettings.DoModal();<br />
}
3. Let me know the result...

Thanks for ur reply.But it doesn't work.The dialog is displaying again and again when i click on the settings option in the menu again and again .
Thanks.

Oops really? I had tested the code in some sample application and it is working fine.
Are you sure that when you select the settings, on the second time, the control is coming to the same MainFrame object's OnSettings? And are you sure that the object is now member of the class?
Can you show me the relevant updations that you made?

Thanks NS17.The problem was that i have given same ID for the two menu options in two menus.It is working fine.
Thanks

So you have two Settings dialog objects, rt? Can you make it global, instead of two member objects? If so only one object will be there.
