Access Violation reprojecting GoogleMapsLayer

Steven1 · October 17, 2016, 5:42pm

Hi guys,

We are using MapSuite Desdktop version 9.0.0.401. We started using this version just a couple of weeks ago. Recently we noticed whenever we try to apply a projection to a GoogleMapsLayer an AccessViolation exception is thrown:


System.AccessViolationException was unhandled

HResult=-2147467261

Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Source=MapSuiteCore

Hi Setven,

Please try to download this package and install it.

https://ap.thinkgeo.com:5001/sharing/A5z5WdSC0

Wish that can solved your issue.

Regards,

Don

Thanks Don! Where can I find the merge modules for distributing the needed files with our application?

Hi Steve,

I think we won’t update the merge module before 10.0 release.

But if that’s hurry for you, please let us know.

We can build a version for you.

Regards,

Don

Hi Don,

For now it will probably be easier to just go back to the older version of MS. Do you know when MS 10.0 will be released?

Thanks!

Steve

Hi Steve,

I just know the new version will be release this year, and now is 10/20, so I think it won’t be too long.

Regards,

Don
