Hi,
I use MW6QRCode ActiveX for generating QR-code. This work fine on machine with Windows 7 and 8, but under Windows 10 when generate some QR-code (not all), system crash. Length of text is ca. 200 characters. Below is LOG file:

Any idea?

I believe that you will need to contact the developer of the ActiveX control to solve this problem.

Hi,
problem occurs, when text to coding into QR was greater than 255 characters. But, when I change creation of ActiveX object from:
oControl := XbpActiveXControl():new()
oControl:CLSID := "{3BB56637-651D-4D1D-AFA4-C0506F57EAF8}"

to
oControl := CreateObject("MW6QRCode.QRCode")

problem was solved. I don't understand....

the Difference is that XbpActiveXControl() use a "Top-Window" to receive Events.

since Windows 10.16299.xx some User have Problem with Windows Scaleing > 100% "Resolution" (PDR 6904).
most those Xbase++ Apps don't start and show XppFatal.LOG

Module: EH
Error Codes: EH: 900 Sub: 0(0) OS: 0 XPP: 0

but it also happens when "something" change "Resolution" like your QR Code Generator.

so use CreateObject() / DynamicCast() if you need to receive Events instead of XbpActiveXControl()
