I have created a new button which I added to the toolbar in MSWord with C#.  Now the functionality I want to give that button is when someone clicks the button I created it will act as if they clicked save and then act as if they had clicked the open button on the toolbar how do I do this?

ex..

 void OnClick_Button(Office.CommandBarButton ctrl, ref bool cancel)
        {
               .....
               .....
               //what can I put to get same effect as the save button being hit
              //I've tried calling event handlers directly but it hasn't given me the same effect as hitting the button.
             //I've tried calling wordApplication.activeDocument.Save() but it produces the error "command failed" and gives no other description
              .....
        }

What version of Office are you using?
Because if it is 2000 you don't have a chance... :(

You can try:
...
using Word = Microsoft.Interop.Office.Word;
...

Word.Document doc = wordApplication.activeDocument;
if (!doc.Saved)
{
     doc.Save();
    // or you can call save as... to specify the file name, used for the open later...
}
doc.Close(/*here there are some ref missing.Value depending on the Office version...*/);

wordApplication.Documents.Open(filename, ref missing.Value....);

Hope this helps.

I'm using Office 2003 so this should be possible I believe.  

I did exactly as you wrote but I still get the error "command failed" on the save() and close() calls.  What's weird about it is that if I put a try-catch block around it and ignore the errors it does save and close the documents correctly (as far as I can tell).  Should I just ignore the errors??  What could they possibly be??  I have event handlers for save and close however I've traced through them and they produce no errors.

Something important is how do I get the new fileName after calling either save() or saveAs().  If I set filename to doc.Name after save() is called the value getting passed in is Document1 (or whatever it was before) not what I save the file as, how do I get that value??  

The open works with no errors, but I need to be able to get the fileName to use it.

On a side note this isn't as important, doc.close() produces warnings do you have any idea how to make them go away.

To get the new file name you can use the property that the Document class has : doc.FullName;

I use the same procedure as above and I didn't get any errors, this is probably because I use VSTO...

But I think you can ignore the error as long as the application continues to run normally, this error may occur because of some serialization methods used by the framework. You can try installing the SP1 for MS Office 2003... it might solve this problem...

Can you put here those warnings?

doc.FullName isn't giving me the new name of what the document is being saved as I'm having the same problem as before.  


I believe the error is because C# doesn't want methods to have the same name, I don't know how to get rid of it but I'm sure there must be a way.

Warning      2      Ambiguity between method 'Microsoft.Office.Interop.Word._Document.Close(ref object, ref object, ref object)' and non-method 'Microsoft.Office.Interop.Word.DocumentEvents2_Event.Close'. Using method group.

You can use the filename object that you use as a parameter in the saveas method to know the file name... if you use the save as method...

The first Microsoft.Office.Interop.Word._Document.Close(ref object, ref object, ref object) is used by the class Word.Document, and second is a Delegate used for the event.

You can use Word.ApplicationEvents4_DocumentBeforeCloseEventHandler to execute an event when the document is about to close,
and ApplicationEvents4_DocumentBeforeSaveEventHandler to execute an event when the document is about to save...

The warning will probably disappear if you put in the using clause referring to Word interop only:
using Word = Microsoft.Office.Interop.Word;
using Microsoft.Office.Core;

Hope this helps.

Thanks a lot the reason the filename wasn't changing was an error on my side in my save event handler.  This was quite helpful.
