Introduction
After the tip on Excel and Word, we are going to do the same for Microsoft Powerpoint.
If you are using Microsoft.Office.Interop.PowerPoint
for Powerpoint related operations in your application, then you must check if Powerpoint is installed in the client machine or not. This tip gives you that trick.
Background
This little piece of code is a result of the research after the comment by Marco Bertschi on my previous tip (How to Check Whether Excel is Installed in the System or Not). Thanks a lot Marco. :)
Nice one, Tadit - It might be even improvable by providing information what the ProgID for the other office applications are (Word etc., but maybe even Visio or MS Project).
Using the Code
We will use the Type
class and its method Type.GetTypeFromProgID Method (String)
.
Gets the type associated with the specified program identifier (ProgID
), returning null
if an error is encountered while loading the Type.
Return Value
Type: System.Type
The type associated with the specified ProgID
, if progID
is a valid entry in the registry and a type is associated with it; otherwise, null
.
For Powerpoint, the ProgID
is Powerpoint.Application
. So, the below code is used to check whether Powerpoint is installed or not.
Type officeType = Type.GetTypeFromProgID("Powerpoint.Application");
if (officeType == null)
{
}
else
{
}
