Thanks.I will try it.

ya that is true but,I had another problem i.e when i opened a dilaog from one of the views and opened a dilaog from the tray menu option with out closing the first one.So,i will have two modal dilaogs opened.Now when i close one window,i am able to access the main window even though one modal dialog is opened,which is a odd behavior.So,i want to get the handle of the child window,which remained when i close one of the window's and disable the main window untill the child window is closed.Is it correct or there is any other option. Thanks

All are Modal dialogs

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.

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.

my application consists of a treecontrol in which i have displayed system files and folders in a tree control similar to the left hand side of Windows Explorer. i am able to copy the folder from the treecontrol and paste it on the explorer where ever we need.Also copy and paste operations are occuring with in the tree control.Now i have added unicode support to my application.The copy to clipboard function is failing.when i copy the folder from explorer i am able to paste it in the treecontrol.But when i tried viceversa i am getting an error message like "the file name you specified is not valid or too long.specify a different file name".how can i make the folder copy from the treecontrol.The code i used is , CDropFiles DropFiles; if(!PrepareFileBuff(DropFiles)) { return; } if (OpenClipboard()) { BeginWaitCursor(); ::EmptyClipboard(); HGLOBAL hMem = ::GlobalAlloc(GMEM_ZEROINIT|GMEM_MOVEABLE|GMEM_DDESHARE, DropFiles.GetBuffSize()); memcpy( (LPTSTR)::GlobalLock(hMem), DropFiles.GetBuffer() ,DropFiles.GetBuffSize() ); ::SetClipboardData (CF_HDROP, hMem ); ::CloseClipboard(); EndWaitCursor(); }
