Feb 12, 2010

I'm writing VB code in Visual Basic 2008 Express and can't seem to figure out how to create a new instance of Excel with VB code. The most common answer appears to be setting an object variable to 'Excel.Application', but that gives an error (Type 'Excel.Application' is not defined).

C# :: Scripting Auto-mation Within Application?

Dec 30, 2009

The software company I work for offers data conversion as a service for new clients who have previously used other similar software. I've written a VB.NET application to automate common conversion operations, and have separate logic between known vendors.particular file layout has become rather common, but due to the nature of how this particular competitor's application stores information, certain fields mean one thing for one client, and another for a different client.Certain elements within this vendor's format change every time, so I've written the application to account for that. Because some data fields mean different things to different vendors, I have to change my mapping code every time. This wasn't an issue when I had one of these every six months or so, but these are becoming much more common and I would much rather find a way to further automate this process.

Refreshing Form During Powerpoint Auto-mation VB 2008?

Feb 3, 2009

I have a VB 2008 Forms application which does Powerpoint automation -- I am opening owerpoint in a minimized window from within my app and am trying to periodically put update messages in a textbox on my main form while the automation is running (it takes a few minutes to complete), but my form window does not want to show these messages until the powerpoint operations are finished. It seems as if I need to force a window refresh or something on my windows form, but I'm unclear how to do that. Below is some code that I'm using that illustrates what I'm trying to do. When I run it, "Step One / Step Two / Step Three" do not show up on my textbox until after the Powerpoint automations are over.

Office Automation :: MultiThreading In MS Office 2007 (Excel, Outlook, Etc)?

Mar 28, 2011

i was wondering if someone could give me the final explanation on what i might be doing wrong here.I spent a lot of time reading around the net and the forum about how to add Threading capabilities to a VB project.

Nos, i've got .NET 4 installed, and i've added the system.tsr and mscorlib.dll files as reference in, say, Excel 2007 (see screenshot).However, when i try to make a thread with anything as basic as "Dim Thread1 As System.Threading.Thread", i get a user-defined type not found error.Indeed, when i use the object browser to see what's in the System file, theres nothing remotely linked to any Threading, and in the mscorlib file, nothing under "Threading" either, just a few Thread related functions, but nothing defining a data type

Office Automation :: Excel File - Set A Reference To The Microsoft Excel 12.0 Object Library

Oct 6, 2009

I'm trying to upgrade a VB6 app to VB 2008. I have read the article in the tutors corner about automating Excel from VB but I cannot get it to work. Heres what I have done:

1) set a reference to the Microsoft Excel 12.0 Object Library

2) Added "Imports Excel = Microsoft.Office.Interop.Excel" to the top of the module

3) in a routine I have added: Dim X As New Excel.Application Here's where I get an error: Error 75 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'.

Office Automation :: Excel Program Leaves EXCEL.EXE Floating After Completion

Feb 24, 2012

I am writing a program that loops through all of the sheets in an Excel workbook and saves each sheet as its own workbook. It turned out to be a bit trickier than I expected, since the Sheet.Copy method creates a strange object (see here for the MSDN discussion that I believe is relevant: [URL]. Anyway, I found a Stack Overflow post [URL] that got me to where I am, which is essentially complete, outside of one hanging EXCEL.EXE process that is left after the program completes, which I believe is a result of the sheet.copy method creating a new workbook (potentially a new application as well?). The other thing I run into, which I believe is related to this, is that even though I have my application set to visibility off, when I run the program, excel still opens up and is visible going through the steps.

Here is my code:

Code:
Imports System.Data
Imports System.IO
Imports Microsoft.Office.Interop

[CODE]...

Now I think the problem comes from the end of the loop, where I try to close the export file and the new worksheet it creates:

Code:
'close excel and release com objects
System.Runtime.InteropServices.Marshal.ReleaseComObject(exportsheet)
exportsheet = Nothing
xlApp1.Workbooks(fileNames(counter - 1)).Close(False)

I can't figure out what to do to release the `ComObject` for the new worksheet that is created. I have been trying all sorts of things, but it always throws a COM error when I do it and if I try to define it as nothing (like I do with exportsheet) is says that it is read only by default, so I can't do it. It seems like it should be something as simple as: System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp1.Workboo ks(fileNames(counter - 1))) But that is not the case. I have tried a few variants of this and I am thinking it has to do with the MSDN link above, but I can't quite sort out what to do. So the code works for my purposes, outside of leaving one EXCEL.EXE after it is done. As far as a test file, I am just using an Excel file with 3 sheets and I put some information on each and change the sheet name, so it is easy to see if it is working or not.

Using The Microsoft.Office.Interop.Excel.dll Library; Does Excel Need To Be On The End User's Machine

Nov 22, 2011

I have been doing a lot of reading on this topic and most folks seem to agree that having Excel is required to use the COM Interop libraries. However they are never specific as to where that should be installed. Does it need to be installed on the machine I am developing on or does it need to be on every machine that I deploy to?

Edit: I should mention that this is desktop development/deployment targeted for all Windows machines.

Office Automation :: Code Hangs When An Excel File Is Opened To A Excel Workbook Object?

Aug 3, 2009

I use the following code snippet

Dim exlapp As New Microsoft.Office.Interop.Excel.Application
Dim xlWorkBook_new As Microsoft.Office.Interop.Excel.Workbook
Dim strOriginal As String
strOriginal = Server.MapPath(Request.ApplicationPath & "/Attachments/") & "abc.xls"
xlWorkBook_new = exlapp.Workbooks.Open(strOriginal)

The code hangs in the last line. It works fine in the development environment. i deployed in windows server 2000 ,where I get this issue. the browser goes half way and throws the below exception after some time

[Code]...

I have set the identity impersonate to true in web config. This should be mostly an access rights issue.I have even provided access rights for the "everyone " user in the excel file and as well for the interop component. Please post ur valuable comments.
