Hi All,
Delphi 10.3.3 or 10.4
ImageEn 9.0.0
We create a new VCL win32-project.
Place components TImageEnView and TTouchKeyboard on the form.
Run the program and get AV in system procedure System._UStrFromPWChar on line 30246.
If you remove component TImageEnView from the program (including its units in uses), then there is no error.
This error needs to be corrected for ImageEn 9.0.0.

Hi
I'm unaware of this issue. Are you using a demo version? Please email me for the latest update.

No, not a demo, I tested it on version 9.0.0.
On the latest version, I can't check it yet
Have you tried to make such a project, put these two components on the form, as you wrote in the letter ? |

Hi
Actually, you are right. It is crashing in the TKeyboardLayouts class constructor of Vcl.Touch.Keyboard when trying to enumerate the resources of the exe.
Presumably it is failing to cope with one of the ImageEn resources. I can't see any good reason for this, but I'll investigate further tomorrow.

Hi
It looks like an issue in EnumResNames of Vcl.Touch.Keyboard. If you add an indexed resource file to your project then you get an A/V.
I just tested a demo without any ImageEn components, only TTouchKeyboard and a resource containing:
5000 RCDATA "test.png"
And it crashed.
At any rate, it is only raises an exception in the IDE so you can ignore it.

I have submited a bug report to Embarcadero:

| It is possible to temporarily ignore this error, but it is not convenient. ; ( |

Does "ignore this exception type" not suppress it?
Is there a TTouchKeyboard alternative?

I forgot to write in the previous message that I am glad that you were able to confirm this error.
If I add this type of error to the exception, then all such errors will be ignored, which is not good.
I just won't use TTouchKeyboard yet (I thought I would use it to enter passwords with protection from keyloggers)
P.S. Please inform me in this thread when Embarcadero gives you an answer on this error. |

Yes, it is a risky type of error to ignore.
I'll let you know when I hear back.
