Any idea what may have caused this error to occur?



Thanks!

Using the stack trace, I added a test to prevent a rendering error on this control. I am uncertain how you achieved this, because the height of the control was 0 which is what produced the error. At any rate, next update will prevent the exception even if this happens.

Awesome! I have no idea how this happened, either. Users can perform amazing tricks sometimes!

I'll second that!

Another user just received this error again...we are on v1.7.0. Here is the error briefing:

Is there anything that I can do on my end?



Thanks!

Are you on 1.7?

Yes he is in 1.7

Well, what I really meant was to verify that the client was on 1.7. Are there any 1.6 assemblies hanging around? Is the EXE that they are running compiled in 1.7?



Looking at the source code, I do not see how this could happen since a test has been placed at the top of the OnPaint() method. So it doesn't seem like the 1.7 build is running on the client. If you look at the stack trace and the look at the source, it should not be able to get to the RenderVerticalBar method.







The above code is at the very top of the OnPaint method. If you look at the stack trace, the OnPaint is the point from which this method was called. So I do not see how this would happen. I can try to setup a test....but doesn't make sense.

The client is running with the most recent version of the application which employs SF 1.7. I totally agree that this is a weird one. It happens (usually) when the application is idle and the user is working in another application. This particular error has been reported on three different client machines. Although, it may be happening elsewhere, it just may not be getting reported.



I will check these workstations to see if any 1.6 assemblies are floating around.
