Extra! ActiveX Component

[Ragnhild]

I am using the Attachmate EXTRA! Object Library to communicate with Extra! from C#.

Opening sessions and sending/reading characters works fine, but when I try to use functions like WaitForString or WaitForCursor they take a bunch of parameters that Ive never seen in any documentation.

Example:
System.Object WaitForCursor ( System.Int16 Row , System.Object Col , System.Object EndRow , System.Object EndCol , System.Object Page , System.Object Type )

What are EndRow and EndCol and Type for ??
And what is the return value, I cant recieve it as a boolean.

The "Wait" objects just pause the code until the string is found. In VB the parameters you've listed are optional. I ususally just use the WaitForString and give at most an X,Y coordinate that tells Extra where to look for the string.

The EndRow and EndCol will allow you to search a specific section of the screen instead of a specific location. I've never used this feature as it seems more difficult and just doesn't have a payoff for your trouble.

*Sigh*
Im still lost.
If someone could show an example of how to use the WaitForCursor method, or any other wait method, in C# I would really appreciate it.

I have tried all different ways that I can think of but I always get 'Invalid cast Exception' or something similar..

Here is one example:

EXTRA._ScreenWait sw = (EXTRA._ScreenWait) scr.WaitForString("ABC", 1, 1, null, null, null, EXTRA.MatchConstants.xRegExp);
            if (sw.Wait(1000))
                ...

scr being the screen object
