Hello,
I trying to implement a routine to create Powerpoint slides using a function
from Microsoft Knowledge base 200551. There are 2 prolblems I am having
with this that I'm hoping someone here can help. I have included the code
from this site below.
The first one is the routine uses early binding to the the Powerpoint
library so the intellisense doesn't work. I am going to need to make some
modifications to this such as passing labels, changing chart types etc. and
it would relly help if the intellisense was working. My efforts to change
this have not been successfull.
These are the dimension statements I've changed:
'Dim oPwrpnt As Object, OpwrPresent As Object '<<=== this is
commented out
Dim OPwrPnt As PowerPoint.Application
Dim OpwrPresent As PowerPoint.Presentation
'Dim oDataSheet As Object, shpGraph As Object '<<=== this is
commented out
Dim oDataSheet As PowerPoint.DataTable
Dim shpGraph As PowerPoint.Shapes '<<=== Is this
correct?
The following Set statement does not compile - fails with "Method or Data
Member Not Found". It is failing on "Shapes" I assume there is an error in
my dim statemet above but I'm not sure how to dimension the shapes. If I
comment it out, others folling will fail.
Set shpGraph = OpwrPresent.Shapes.AddOLEObject(Left:=LLeft, _
Top:=lTop, Width:=lwidth, Height:=lheight, _
ClassName:="MSGraph.Chart", Link:=0).OLEFormat.Object
I'm really hoping that someone will take a look and tell me where I've gone
wrong!
Thanks,
Vic
