IMouseCursor does not stay set to hourglass whle query runs

CarlosPiccirillo

Hi everyone,

I have a form which has a listbox on it displaying all lakes in the state so the user can select which one they want to load and zoom to.

On the InitializeComponent(); section of a C# form, I set the mouse cursor to an hourglass with this code:

IMouseCursor pMouseCursor = new MouseCursorClass();
pMouseCursor.SetCursor(2);

Right after this line, the code calls another method which queries the lakes layer, puts all of the names into an array and returns this to the listbox for display. As soon as the code goes to the method that does the query, the cursor returns to the pointer instead of staying an hourglass. Trying to set the cursor back to hourglass inside of this query method has no effect.

This query can sometimes take up to a minute to run depending on network traffic so I definitely want to show the user that code is running and not have them think the program is locked up.

Any ideas on how to fix this?

Thanks,
Carlos

Carlos,

Have you tried to implement the cursor from the parent Windows form?

Prior to the method call, set the cursor (VB.NET):

Windows.Forms.Cursor.Current = Cursors.WaitCursor

After the method and the return to the form, re-set the cursor:

Windows.Forms.Cursor.Current = Cursors.Arrow

Hope this helps,
