Force a .Net Extension to show itself Your last visit to this thread was on 1/1/1970 12:00:00 AM

This may be a no brainier, but it's giving me a hard time.

I have a .Net extension that retrieves data from an UniData database on an AIX machine. The process of getting the data is rather involved requiring up to 7 different SQL statements. The data is displayed to the user in 7 list view controls contained in the .Net Extension. As such the data gathering is a bit time consuming.

My problem is getting the control to show itself while gathering the data. I need to give the user something to see while gathering the data.

I have tried many ways to get the control to paint itself but have not succeeded. I have called .Show, .Update. Inside SLX script I even called the .Net extension twice, once without data processing and then a second time with data processing with a ProcessWindowsMessages between the calls.

After the control is displayed, the user can select a different date range and start the data gathering process again. At this point I have no problem updating the screen at various steps of data gathering to let the user know what is going on.

The client wants the display to be pre-populated based on the current date. they do not want the user to have to hit select when it opens.

I am hoping to avoid creating the display in SLX and passing and parsing all of that data inside SLX script.

Can anyone suggest how to get the user interface to paint while processing data in the background?

The problem that you are having is that the code is executing in a single thread.

If you are not doing this yet, you should use a separate thread to do all your data retreival, thus allowing the first thread to respond to other Events (e.g. Paint the form, relying updates to the user, a Cancel button if applicable).

Since you are using .Net, the threading is quite simple to do by using the BackgroundWorker component.
