MailMerge -- exception in AddIn

Hi, I use this mehod as onClick

var
sPath, format: OleVariant;
rg: Range;
Start, Finish: OleVariant;
doc: _Document;
begin
sPath:='c:\input.rtf';

WordApp.ActiveDocument.MailMerge.OpenDataSource(sPath, EmptyParam, EmptyParam,
EmptyParam, EmptyParam, EmptyParam,
EmptyParam, EmptyParam, EmptyParam,
EmptyParam, EmptyParam, EmptyParam,
EmptyParam, EmptyParam);

Start := 0;
Finish := 0;



Rg := WordApp.ActiveDocument.Range(Start, Finish);
doc := WordApp.ActiveDocument;
WordApp.ActiveDocument.MailMerge.MainDocumentType := wdFormLetters;

WordApp.ActiveDocument.MailMerge.Fields.Add(rg, 'Vorname');

WordApp.ActiveDocument.MailMerge.Destination := wdSendToNewDocument;

WordApp.ActiveDocument.MailMerge.MailAsAttachment := False;

format := false;
WordApp.ActiveDocument.MailMerge.Execute(format);


The letter is created as a new document, but the I get an exception. If I place a ShowMessage as last line, it is displayed and after clicking ok I get the exception. The method ends directly, there is no more code.

I used the code in other applications which do not use adx. Thus, I have no idea what the reason could be.

Any help?

Thanks,
Uwe

Hi Uwe,

I have tried your code and see no exceptions. Could you please send me the whole project.

Hi Dmitry,

it's in the middle of a bigger project; thus, it's hard to extract it for you as a separate project.

Maybe you can provide me your test-project? Then I can check if it works and then investigate the problem in detail.

Thanks,
Uwe

You are right!!

There is no problem when I try it in a separate project.

Thus, I have no idea what thre could be different...

I'll try some more.

Ok, I found out that it is this what causes the problem:

I have two TForms which I create in AddInModuleAddInInitialize:

Application.CreateForm(TFormImport, FormImport);
Application.CreateForm(TFormOptions, FormOptions);

If I remove the two lines, it works without problem.

Do you have any idea what the reason could be?

Thanks,
Uwe

Hi Uwe,

No ideas so far. Did you use any third-party components on your forms? I will try to reproduce this on our test PC.

I use a Grid which is connected to a DB in a TDataModule (created in the same way as the TForm).

As far as I tested it, only this form makes problems. I have tested a simple one with only one TLabel -- no problem.

Can I not use a DB in an AddIn?

Thanks,
Uwe

I see no reasons that prohibit doing this.

Maybe you can provide me your test-project?

Sure, I have just added TDataModule:

Maybe I do not free all the things correctly. Sounds somehow like the problem when creating items dynamically. Maybe I can somehow get removed all my AddIn from Word?

Unregister all your add-ins. Open the COM Add-ins dialog box in MS Word and make sure there are no add-ins in the list. Close MS Word and remove normal.dot. It seems that's all.
