ltmm175.dll version 17.5.0.25
LeadTools.Mutlimedia.dll version 17.5.026

The ConvertCtrl is being created on a separate single thread apartment (STA) thread.

This worked prior to using the latest LTMM 17.5 bits.

PS. I tried to the BBCode 'code' tag to format the stack trace but kept getting an error when I tried to preview it.

After a little more research we found that the C# Convert sample fails as well starting with LTMM version 17.5.120701.024608 up to present.

The last one that works is 17.5.120405.115044

Bill,

One of my colleagues tested a similar issue and it was subsequently fixed. Please download the latest version of Multimedia 17.5 and test with it. If you don't have download instructions or you still face problems getting the fix, please send an email to support@leadtools.com and include the following:
1. Your toolkit serial number (do NOT post it here).
2. The build number (file properties version info) of Leadtools.Multimedia.dll. The build format should be 17.5.0.NN, where NN are 2 digits only.
3. A detailed description of the steps and programs needed to reproduce the issue, including the VS version, the Windows version and the .NET framework you're using.
4. A Link to this forum.

You must also use the constructor overload allowing you to specify whether you wish to create the control in a windowless environment.

Pass "true" for the parameter and that should get rid of this error.
