Webview example crashes debugger

[novablue]

On Windows PB 6.11 x64 running the Webview example from the help file will crash the debugger when i click on one of the buttons.

"The debugger executable quit unexpectedly"

Compiling it without the debugger works without crashing. Is anyone else experiencing this?

Doesn't happen for me on Windows 11 IoT LTSC 2024 with PB 6.11 (x64 and C backend).

Looks OK here, can anybody else confirm ?

[Mindphazer]

No problem here, works as expected (PB 6.11 x64, Win 10 22H2)

[Marco2007]

I just know "The debugger executable quit unexpectedly", when using a wrong folder for creating the compilation exe and/or a virus scanner (e. g. Defender) is blocking the debugger.

[Fred]

What do you mean by 'using wrong folder' ?

[Marco2007]

Sorry, I meant "forbidden for Defender". I don't know which folders are not allowed.
The %temp% folder definitely causes problems.

This example with "Create temporary exe in source directory" checkbox unchecked -> Debugger crash (due to Defender)

Code: Select all

For i=1 To 10
Debug "ok"
Delay(160)
If CreateFile(0, "c:\test1.exe")
  Debug "ok"
CloseFile(0)
EndIf 
Next 

I also noticed problems with other folders a few months ago, but I don't remember, which folders caused problems, when "Create Exe..." was disabled -> Since I'm using OneDrive and checked "Create ..." -> no crash.

Btw almost the same issues for the example in the first post. There's no chance for me to run the code from "\Examples\Sources\" ...
With or without checked "create exe" ... but I can run it from e.g documents without any problems.

Win 11 x64 ...

Debugger crash (due to Defender)

I think you know what to do.

[Marc56us]

Search where is the last PureBasic_Compilation*.exe
(use SearchEverything)
Save you code with a name

PS.

Code: Select all

CreateFile(0, "c:\test1.exe")

In Windows 10+, normal user (without admin rights) can't write

• in root dir on Windows system disk (C:\)
• in program files (%ProgramFiles% %ProgramFiles(x86)%)
• in system dir (echo %windir%) (i.e C:\windows)
