I think you are fine here; although your program uses Winforms (Managed C++/CLI) your question relates to C++ and Windows API.

It's time for a new signature.

I'm using Visual C++ 6 on Windows XP. My program uses COlePropertyPage property pages. One of them has a List Control. When the user clicks a certain part of my List Control, a dialog box appears, and when the user is done with it, it disappears. However, if the dialog box is moved over part of my List Control, when the box is closed that part is erased and set to gray, the color of the underlying COlePropertyPage. I want the List Control to refresh itself when the dialog box disappears. The control will refresh itself if another window is placed on top and then removed. Of course, I don't want the user to have to do that! The List Control should refresh immediately when the dialog disappears.

I'm trying Invalidate(), UpdateWindow() and RedrawItems() one at a time and all three at once. It makes no difference. Actually, I note that my DrawItem function is called even without calling those repaint functions. Calling them just repeats the DrawItem function being called. However, the DrawItem call has no effect. Also I've tried setting the control to dirty with COlePropertyPage::SetControlStatus(). Nothing works.

Thanks for any help..

Try the SetImageList() method.

i try to use this code.

SHFILEINFO fi;
	BOOL bReturn = FALSE;
	HIMAGELIST himl = NULL;

	ZeroMemory (&fi, sizeof (fi));
	himl = (HIMAGELIST)SHGetFileInfo (filename, 0, &fi, sizeof (fi), SHGFI_ATTRIBUTES | SHGFI_SYSICONINDEX | SHGFI_SMALLICON);
	bReturn = m_ImageListSmall.Attach (himl);
	m_LIST.SetImageList (&m_ImageListSmall, LVSIL_SMALL);

I have found only same image showing in all column(what ever file is .doc or .pdf).
Can you guide me for this problem.

How to declare a three dimensional array

How many images are in the image list? When you add items to the list control, what index are you using for the image?

I have been to that site but it only talks about it without examples. I know it can for instance be declared as follows:

int rates[10][4][3];

The declaration is what has been shown on the site. But I want to know how to initialise the array when it is declared, and know how the indexing will refer to a particular value in the initialising list.

Try the information here[^]. Although this only covers 2D arrays, you can think of the third dimension as a number of 2D arrays one on top of the other, the index increasing as you go further down the planes.

It's time for a new signature.

Use boost::multi_array[^] to create arrays of any dimensions.

In fact Ive called ShellExecute() to execute another application when clicking on the button on the dialog. And I want to suspend the current dialog until the app executed by ShellExecute() finishes its tasks. But I dont know how to do it. Can anyone help? Thanx in advance.
PS: I dont know whether WaitForSingleObject() will work.

If you WaitForSingleObject on the handle of the spawned process the thread doing the waiting will stop until the spawned app completes.

To get the process handle it might be an idea to use ShellExecuteEx as you can find out the handle of the spawned process a bit easier.
