    Posted: 25 July 2011 at 1:05am
I am just starting to use the Chart control.
During testing for this I discovered a Fatal Windows Crash.

Simply put I have a Chart control and I initially display a Pie Chart.
I then give the user a PopUp menu (right click on the chart) to select from either a Bar or a Pie Chart.
The user can select Bar and then change again to Pie....etc

Changing from Pie to Bar is not a problem, however once the Bar chart is showing if your "right-click" directly on the chart area and select Pie you get a Windows crash. If you right-click not directly over the Bar chart area it does not crash.

I have checked through the code and cannot see where I may have gone wrong.
I have attached a zip of a sample project that displays the behavior.
uploads/2555/CodejockCharttest.zip

Hoping someone (at Codejock) can help me?

Thanks
Trevor.

Hi,
 
I tried with your test project and I couldn't get it to crash.
 
btw The only thing I noticed that the VB popup menu is drawn with background of BAR chart (selecting pie when bar is active) just for a split second...
 
Good luck Wink

Aaron,

Thx for trying.

It happens around 95% of the time.
Here is a video of it crashing just in case my instructions weren't 100% clear.

Hi,
 
I did click on Bar about a hundred times... Outside, inside, everywhere... Not a single crash. Maybe something to do with version GDI dll 
 
C'mon support, why don't you guys reply?

Hi Oleg,
 
Thanks for reply, I tried already with new version (V15.1.0) without knowing it hehehe
 
Seems something with V15.0.1   I tried and it crashed immediately as described by thread starter.

So you say you see it with 15.0.1 but not 15.1.1?  I tried that sample with both 15.1.1 and 15.0.2 and couldn't see the crash.

Thanks to all that posted.

I have re-tested using v15.1.1 and it no longer crashes.
Thanks CodeJock seems like you fixed it!
