iniWrite an empty string

[bigred]

I seem to have a problem with iniWrite in VB6 when I try and write an empty string to the key.

Is there any way to clear out a key?

I could have the code replace an empty string with something that I could handle later when I go to read the string, but thats not preferable.

Any ideas?

Have you tried vbNull or vbStringNull? These might erase the value.

Ok, so you're saying set the string to one of those and then try and write it to the ini key?

I'll give it a try.

EDIT: Weird, it seems to have written "1 " (a one and a space) to the key when I use vbNull. Any ideas?

Also vbStringNull didn't work. VB6 thought it was a variable.

vbStringNull is a variable, you could try sending that as your IniWrite parameter. I assume that in your code you set a string = vbNull, try changing its data type to a variant and see if that works. other than that without seeing your code there isn't a lot I can do to help. Hope something here was of assitsance!

vbStringNull is a variable? I don't understand how that is helpful here?

No I don't set the string to equal vbNull, when I do that it writes a "1" to the key.

Here's the chunk of code I'm reffering too.

If ListSelMaps.ListIndex = -1 Then Exit Sub
    For iCounter = 0 To ListSelMaps.ListCount - 1
        ListSelMaps.Selected(iCounter) = False
        ListSelMaps.Selected(iCounter) = True
        If ListSelMaps.Selected(iCounter) = True Then
            Select Case iGameMode
                Case 1
                    sDA_Maps = sDA_Maps & ListSelMaps.Text & ","
                Case 2
                    sLC_Maps = sLC_Maps & ListSelMaps.Text & ","
                Case 3
                    sDM_Maps = sDM_Maps & ListSelMaps.Text & ","
            End Select
        End If
        ListSelMaps.Selected(iCounter) = False
    Next iCounter

    Select Case iGameMode
        Case 1
            If sDA_Maps = "" Then
                aix.IniWrite sTSMdata, "MAPS", "DiscArenaSelected", sDA_Maps
                Exit Sub
            Else
                aix.IniWrite sTSMdata, "MAPS", "DiscArenaSelected", sDA_Maps
            End If

Well I am fresh out of ideas for using AutoIt to do it. You could always access the registry api directly. Search Planetsourcecode.com for ways to do this.

The registry? I'm working with an ini file.

[Matt @ MPCS]

Sorry that is what I meant... the functionality is almost identical for the API. It was late when I posted that so forgive a sleepy man.

Heh, no worries.

I'll check out that site you mentioned. Thanks.

[bigred]

I checked it out. Still no go.

Why does the autoitx iniwrite command crash the program?

Anyone have any ideas?
