Performs all ini file functions from within a single dll file.
Inputs
Key name
Section name
New Key Value
Assumes
You need to add the Inifunctions.dll to the project reference.
then insert the following code in general declaration
eg.
Dim g_IniFunctions As New CInI
then use in your program the following code:
dim RC as variant,R as long,I as long
With g_IniFunctions
SectionId = .SectionGet(Section name)
End With
For R = 0 To UBound(SectionId)
I = InStr(SectionId(R), "=")
Combo1.AddItem Mid(SectionId _(R), I + 1)
Next
dim strReturnWhat as string
strReturnWhat = g_IniFunctions.KeyGet(section name), KeyName)
The other inputs are self explanatory.
ini file name is inside the INIfunctions.dll
save class as Cini.cls and compile as INIFunctions.dll
Code Returns
IniFunction.KeyGet returns the value of a specified key.
IniFunction.SectionGet returns all values in the specified section to a variant
Side Effects
None that I know of, But I have only used it on VB6.
