F#-Compiler has Problems with Microsoft.Office.Interop.Word.dll
f#.net

Hello everyone,

In the last few days I tried to port an MS Word Addin written in C# partly to F#. Actually I thought, it wouldn’t be a big deal. But as I tried to use some Interfaces of the Microsoft.Office.Interop.Word.dll, I had a strange experience with the F#-Compiler.

So let’s assume I wanted to write a simple function, that does something with the current selection in a word document. It would look something like this…

let doSomething (sel:Microsoft.Office.Interop.Word.Selection) =

sel.Paragraphs …

The F#-compiler recognizes the Type Microsoft.Office.Interop.Word.Selection. But as soon as I try to access a property of the interface Selection as in the line sel.Paragraphs … the F#-Compiler tells me, that the field Paragraphs is not defined. Casting the sel value to Selection like (sel:>Selection) doesn’t help either. Amusingly I get no errors when writing the equivalent Code in C#.

So why on earth does F# not come along with the Microsoft.Office.Interop.Word.dll? Actually I thought that F# is compatible to all .net dlls.

Regards

Simon

I do not repro this on my box. Specifically, in VS2010, if I add a reference to Microsoft.Office.Interp.Word version 11, and then type

1
2
3
4
5
6

 

let doSomething (sel:Microsoft.Office.Interop.Word.Selection) = 
    sel.Paragraphs

it works, no squiggles, right return type for doSomething. Can you specify more details of your environment or repro steps (which version of F#, VS, ...)?

Hallo brianmcn,

thanks for trying. Well after removing and adding the Microsoft.Office.Interop.Word.dll (Version 11) reference again, the problem disappeared.

I really don't know why my VS2010 had these problems the first time.
