Redwolfe,
To insert a symbol into a powerpoint textbox:
MyTxtBox.InsertSymbol FontName:="Symbol", CharNumber:=226
this inserts Character 226 from the Symbol font set to a textbox called MyTxtbox.
To run this when opening the file put the code in a sub called AutoOpen. To do this insert a new Module by right clicking on the project explorer, here is some more code:
Sub AutoOpen()
MyTxtBox.InsertSymbol FontName:="Symbol", CharNumber:=226
End Sub
What this does is every time you open your powerpoint document it will insert Character 226. Unfortunately, I don't know how to open the symbol dialog. You could create one yourself - this may be a little time consuming.
You could open a form where you enter the font name and the character number when you open the document.
I don't know if this helped at all. This is the limit of my knowledge with symbols and I'm not very familiar with powerpoint macros.
Cheers,
