Hi,

I have been working on developing an Excel AddIn with some User Forms, Task Panes, UDF, ToolBars and Ribbons. However, when I try to access the Excel objects from the User Forms or TaskPanes, I receive an Exception from HRESULT:
System.Runtime.InteropServices.COMException was unhandled by user code
ErrorCode=-2146827284
Message="Exception from HRESULT: 0x800A03EC"
Source=""
StackTrace:

InnerException:

Reviewing AddInExpress forums, I found the following code.

Dim MyHostApp As AddinModule = AddinExpress.MSO.ADXAddinModule.CurrentInstance
MyHostApp.ExcelApp.ActiveCell.Select()

I tried reinstalling both, AddIn Express and Visual Studio 2008 however the error still there.

Currently, I am working with Visual Studio 2008 Team System and MS-Office 2007.
Add-In Express 2008 for .NETv4.3.1910

Any suggestion?

Hi Carlos,

Could you send us the sources to the support e-mail address (see Readme.txt)?

Hi Eugene,

I can?t send you my whole project, because it needs to connect to a SQL database in order to work. However I tried in another project with a simple windows form and a simple button. The result was the same. I think that with a TaskPane the result must be the same also)

I will send you this simple project.
The code inside the windows form is like this:

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim MyHostApp As AddinModule = AddinExpress.MSO.ADXAddinModule.CurrentInstance
Dim rng As Microsoft.Office.Interop.Excel.Range
rng = MyHostApp.ExcelApp.ActiveCell

rng.Formula = "=100+10"

End Sub
End Class

Hi Carlos,

Don't publish any e-mail address on the forum. That is what spammers are looking for.

Unfortunately, the specified e-mail address doesn't exist. Please see the Readme.txt file.

I suppose you refer the file in the Addin Express instalation folder.

Ok. I sent you the same file to this email address.

Hi Carlos,

I have tested the add-in. It works fine for me. But I didn't find the adxloader.dll and manifest file in the Loader folder of your project. What version of adxloader do you use?

P.S. I have noticed that you don't release COM objects in the code. For example, an instance of the Microsoft.Office.Interop.Excel.Range class stays alive.

Eugene,

Both files are in the folder you said (version 4.3.1910.0).
Do you think I am doing something wrong when I setup the project?

Could you send me the same sample project?

Eugene,

Finally, I think the problem is solved.

For your knowledge database.
http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q320369

Something related with the non-English language configuration in my computer. (spanish configuration).

If I would have any other problem, I will contact you.

Thank you.

:D
