Deleting an INI section

[phinoppix]

The MSDN docu on WritePrivateProfileString states that setting to NULL the value parameter will delete the key. Tried to follow that and it did deleted the key name and value pair, BUT left the equal sign.

[section1]
key1=value1
=                 'equal sign left!!!

Is that a norm with the function? Or am I missing something?

I used the ffg similar code:

Dim pvarReturn 
pvarReturn = WritePrivateProfileString("section1","key2",vbNullChar,"C:\TEMP\test.ini")

TIA

Use vbNullString instead of vbNullChar

Sorry for the late reply. I'm about to try your suggestio, but one question, how does vbNullChar differ from vbNullString?

 

[wanmaster]

I'm not sure, but I think (comparing with c++):

vbNullChar = Chr$(0)
vbNullString = NULL (but still a string)

The latter is a bit weird, but you could say that it's not Chr$(0), not "", but sort of a null of type string.

Haven't tried looking what MSDN has to say, but it is indeed awfully weird (or maybe it's just because I don't know anything about C). However, if vbNullChar=Chr(0), I guess I'll be using vbNullString more often with text returning APIs. Although, I've read Chr(0) is more likely useful with communication stuff.

By the way, tnx for help. It worked.
