I am having problems when CNiWordApplication is called

[DrObb]

I have a macro routine that intensively plots a screen and copies the image into a file (.bmp).  The macro routine keeps repeating for about 15 - 20 screen shots  (images).  Then the macro routine opens MSWord to insert all the pictures into a word document.  For the fist time running the program, I can go through all the plotting, saving images, open up the word, insert the pictures into word with no problem.  However, when I run for the second time (withouth exiting the program and re-execute the program), the plotting routine will crash.  I troubleshooted the problem and found out that if I did not open the MS word

(    CNiWordApplication application;
    CNiWordDocument document = application.CreateDocument();    )

Then the software can run repeatively without the plotting routine crashing.  However, if I create a document and did not go through the inserting the images, the software will crash on the plotting routine on the next run.  Is there anything I should be aware of when I declare CNiWordApplication application; ?  I am at my wits end here and our client is not very happy. 

I will appreciate your helps.

Hi Yajai,

The first thing I would suggest is checking out this article that covers the basics of using the Microsoft Word Automation Interfaces.

Just to clarify -- when you run the program the first time, it executes as it should.  When you run it again, however, it will crash during the plotting/saving process.  Would you mind posting a screen shot of the error message you have been seeing?  Also, what do you mean when you say you create a document but don't insert the images?  Are there times in the program when it does not insert all of the images it captures in the Word document?
