Megatron or other GURU error in Ini read

[Jethro]

This is weird?

sSectionName = "Hello Newman"
sValueName = "Episode"
sIniDefault = "c:\wherever\seinfield.ini"
sIniFile = sIniDefault
Dim lReturnCheck As Long
Dim sReturnValue as String * 50
'
lReturnCheck = GetPrivateProfileString(sSectionName,sValueName,sIniDefault,sReturbValue,Len(sReturnValue),sIniFile)
'
If lReturnCheck = 0 Then
  GetIniValue = ""
Else
  GetIniValue = Trim(sReturnValue)
End If

Ok the problem is that even if the ini file does not exist lReturnCheck returns a value of 21 or 22 and sReturnValue has the ini File Name and 10 or so return characters.

How come lReturnCheck isn't returning 0?

GetPrivateProfileString doesn't indicate by it's return value whether it has succeded in retriving the information from the file. It always return the length of the textbuffer, that is the lenght of the text retrieved.
And since you give a default value, it vil return the default value and the length of the returnvalue.

Thats it!!!!

A suggestion might be, to replace the default value with a empty string : "", that way you can detect the error be testing the returned string:

if strReturn = "" then debug.print "ERROR"

[Megatron]

It should be returning the number of characters in sIniDefault (this API is not one of those Success/Fail types).

[Jethro]

That was quick, (as my wife is apt to say)

Good point AIS, will try that out...excellent works !!!!!!!!!!!!!!!!

Now all l have to do is figure out why on earth l had the "* 50" in the first place?

Our office net is down, am on site, so expect a heap of questions in the next few days...can never remember the API calls.
