Dim originally (in BASIC) stood for Dimension, as it was used to define the dimensions of an array. (The original implementation of BASIC was Dartmouth BASIC, which descended from FORTRAN, where DIMENSION is spelled out.) Nowadays, Dim is used to define any variable, not just arrays, so its meaning is not intuitive anymore.
First of all, go get MZTools for Visual Basic 6, its free and invaluable. Second add a custom error handler on every function (yes, every function). The error handler we use looks something like this: On Error GoTo {PROCEDURE_NAME}_Error {PROCEDURE_BODY} On Error GoTo 0 Exit {PROCEDURE_TYPE} {PROCEDURE_NAME}_Error: LogError “Error ” & Err.Number & ” (” … Read more
Contrary to what others have said, it IS possible to get run-time type information for UDT’s in VB6 (although it is not a built-in language feature). Microsoft’s TypeLib Information Object Library (tlbinf32.dll) allows you to programmatically inspect COM type information at run-time.

I personally prefer not using default properties that don’t take parameters. It makes the code less confusing IMO. In VB.NET the default property must have a parameter, so this situation does … Read more
Depending on your situation adding #If False Then Dim CorrectCase #End If might help.
After months of research I’ve come up with this. Public Function PrettyPrintXML(XML As String) As String Dim Reader As New SAXXMLReader60 Dim Writer As New MXXMLWriter60 Writer.indent = True Writer.standalone = False Writer.omitXMLDeclaration = False Writer.encoding = “utf-8” Set Reader.contentHandler = Writer Set Reader.dtdHandler = Writer Set Reader.errorHandler = Writer Call Reader.putProperty(“http://xml.org/sax/properties/declaration-handler”, _ Writer) Call … Read more
You may also want to try setting up Reg-Free COM for your project. There’s a freeware called Unattended Make My Manifest that will do most of the work for you.
Speaking from experience (I run VB6 almost every day in Windows 7 – 64 bit), there is no problem getting it running, in fact you do not have to run it in any kind of compatability mode. There are a couple of Caveats though: Use the installer from a recent (within 5 years) version of … Read more
