Hi,

it seems like PowerBuilder 2022 R2 2828 ignores the path of LoadWithDotNetFramework("PATH")

the following example:

ll_rc = lnv_Assembly.LoadWithDotNetFramework ("C:\example\program1\test.dll")
if ll_rc < 0 then
	e.SetMessage(lnv_Assembly.errortext)
	throw e
end if

ll_rc = lnv_Assembly.CreateInstance ("Test.TestText", lnv_test)
if ll_rc = 1 then
  try
    ls_text = lnv_test.getText(as_text)
  catch(Runtimeerror re)
    e.SetMessage(re.text)
    throw e
  end try
End if

After i compiled the program and ran it from the command line i get the following problem:

Command Line Path = "c:\example\" and calling "c:\example\program1\program1.exe" causes non Error but ls_text is Empty.

Command Line Path = "c:\example\program1\" and calling "program1.exe" causes non Error but ls_text is Filled.

Command Line Path = "c:\example\" and exists "c:\example\test.dll" calling "c:\example\program1\program1.exe" causes non Error but ls_text is Filled.

 

Conclusion

LoadAssembly is looking for the dll, but it seems the dll must be located in the CurrentDirectory.

 

do you have an ideas.. thanks

Stephan

 

edit:
bad solution, but works:

ls_old = GetCurrentDirectory()
ChangeDirectory("c:\example\program1")
// complete code
ChangeDirectory(ls_old)
