We have been using the Topaz signature capture for years.  We have recently updated our application from PB 2019 R3 to PB 2022 1900 and now it has stopped working.  It seems it cannot locate the COM port anymore. There is not much too this control so I am a little confused to what might have happened or how to debug.  I tried running Process Monitor to see if there is anything odd but it all looks correct to me.

I have contacted Topaz but they do not have PB 2022 so they cannot test.  I will have them download a demo version so they can try and debug it but I am wondering if anyone might know what could be happening.  Could there be an issue with the Visual Studio version PB uses now? Is there a list on unsupported OCX things I need to be aware of?  I even took the sample PB application which was done in PB 9 and converted it to PB 2022 and the same error happens.

Thanks for your input,

Chris Craft
