[Solved] Bad parameter type: a string is expected

GetPathPart returns a string, so I expected this to work:
Code: Select all
Global sgCurrentFile.s = "C:\MyFile.txt"
Procedure SaveFileAs()
;---------------------
Static sDefaultSaveAs.s = GetPathPart(sgCurrentFile) ;Line 5: Bad parameter type: a string is expected.
sDefaultSaveAs = SaveFileRequester("Save File As", sDefaultSaveAs, "*.txt|*.txt|*.*|*.*", 0)
MessageRequester("Save File As", sDefaultSaveAs + " Saved", #PB_MessageRequester_Ok | #MB_ICONINFORMATION)
EndProcedure
SaveFileAs()
If 'Static' is replaced by 'Protected', it does work.......
The reason for the failure is not
"Bad parameter type: a string is expected.", it is
"Only literal expressions are valid for 'Static'"
Isn't that a shame though? I just want to initialise the static var with the currently active file for the first time SaveAs is called, so the file browser will open the folder most likely to be used.

Works if 2 separate lines...
Static sDefaultSaveAs.s
sDefaultSaveAs = GetPathPart(sgCurrentFile)

Code: Select all
Static sDefaultSaveAs.s = GetPathPart(sgCurrentFile)
This can't work....
Imagine : Every time you call the procedure, you set the "STATIC" var to a default
So it's like "Protected"

The above syntax can only be used to assign a constant value at compile time.

Yeah, I was thinking the Static line is ignored after initialisation, but as Skywalk has pointed out with his example, my thoughts were gibberish!

Looking at the code you wrote you wanted to initialize the static var with
the path of the ... etc.
Code: Select all
Procedure SaveFileAs()
Static sDefaultSaveAs.s
If sDefaultSaveAs = ""
sDefaultSaveAs = GetPathPart(sgCurrentFile)
EndIf
sDefaultSaveAs = SaveFileRequester("Save File As", sDefaultSaveAs, "*.txt|*.txt|*.*|*.*", 0)
MessageRequester("Save File As", sDefaultSaveAs + " Saved", #PB_MessageRequester_Ok | #MB_ICONINFORMATION)
EndProcedure
Don't know what you want to happen on subsequent calls, but this does what you asked.

Hi luis - yes, I changed the code, same as your snippet. First time SaveAs is called, the default folder is the same as the current file. For the SaveFileRequester line, next time the default folder is the folder last saved-as to. Works like a charm.
