I just want to ask whether I can automate Excel without microsoft office excel installed on machine, I tried but it failed to do automation, does anybody know how to do it without excel installed on machine?
View 5 RepliesI'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'.
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.
Basically I've coded an Excel 2007 project in VB.NET 2010 that allows you to create charts with a fair amount of interactivity. I want the user to be able to save and reopen this workbook and still have that interactivity in any already-created charts, so they don't have to re-create them.
When I create the charts, I use Sheet1.Controls.AddChart(...), which returns a Microsoft.Office.Tools.Excel.Chart with which I can handle events and such. However, when I reopen the file and look through the Sheet1.Controls collection, there are no Chart objects. Accessing the charts through Sheet1.ChartObjects.Chart gives me Interop Charts, when I need the Tools Charts.
I need to create an excel file from the database records. I fetched and put the data in an excel file and tried to save that file as follows.

I'm using Microsoft.Office.Interop.Excel in VB.Net in order to export an .xls file as a .pdf file. This was the only method I could find without relying on third party software to be installed on the running machine or using an expensive add-on to Visual Studio. This method requires opening excel and saving a file through the code.
My problem is that I only have a trial version of Microsoft office as I never actually use it. Well the limitation of times I can open it is up as I have run the program enough times for debugging purposes and now I can't continue development on this application. Is there a development kit for visual studio that provides the API I need for this functionality without actually having Office installed? I don't need Microsoft Office so I don't want to have to buy a full version just to develop and test an application.
I've looked at some options like this, but there is very specific formatting that needs to remain intact in the .xls for the conversion to .pdf that doesn't seem to work if I use an intermediary format. I've also read a little bit about the openOffice API, but is that compatible with .Net? If so, can someone point me to a tutorial that explains how to use the API with .Net? Specifically VB if possible, but I can work with C# code.

View 10 RepliesI have create Office Excel application in my machine(XP). and i have placed the application in windows server 2008 giving the following error.
Microsoft Office Excel cannot access the file 'serverInput.xls'. There are several possible reasons:
The file name or path does not exist.The file is being used by another program.The workbook you are trying to save has the same name as a currently open workbook.
both client and server systems installed office 2007 and added reference microsoftexcellibrary 12.0
created assembly for the application and calling the code from the form.
I am developing an application using excel automation.The worst thing is the client's side doesn't have excel installed.What is the solution for this case?

I have a software that writes data to Excel sheet. I'm using Microsoft Excel 11.0 Object Library for this. Everything is working fine so far, but apparently the drivers require Microsoft Office installed onto the computer.

I am using the Microsoft.Office.Interop.Excel library in VB.Net on an excel sheet that is protected. All of the protected settings are working fine except that I cannot set Select Locked Cells which shows when you are using the Excel protect sheet interface but I cannot see how to set this to false using the library. I have tried all of the different values in the protect method but none of them toggle the value.Excel protected sheet menu Below is the code snippet I am using to get my workSheet, populate some values, and then protect the sheet. GetWorkSheet is an internal method which will return a WorkSheet object, and invoiceData is a datatable which has the data which is being added to the spreadsheet.
Dim newSheet As Worksheet = getWorkSheet(newSheetName)
' Make the current Work Sheet active so that it will be accepting the data.
newSheet.Activate()
newSheet.Unprotect(sheetPassword)

I have Visual Studio 2010 and a VB Project that had a reference to Microsoft.Interop.Excel 12.0. Well recently I changed the reference version to 14.0. That was actually a mistake and now I need to bump it back down to version 12.0. However I get this error in my project now...
Project 'MyProject' requires a reference to version '14.0.0.0' of assembly 'Microsoft.Office.Interop.Excel', but references version '12.0.0.0'
of assembly 'Microsoft.Office.Interop.Excel'.
I tried removing references and adding the com object to, but no avail.
I am using VS .net 2003 and developing a program that calls Excel. The development computer only has Excel 2003, and the target machine only has Excel 2007. Would it be possible to install Excel 12 Object Library in the development computer without installing Excel 2007?
View 4 RepliesI 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.
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

I am creating a VBA application using Excel 2007 and would like to make virtually all of the standard Office and Excel menus invisible to the user and present to the user only my custom menu controls. I have been successful in doing this for all objects on the Ribbon as well as those on the Microsoft Office Button Menu, with the exception of the "recently opened files list" box, that also has the "Excel Options" and "Exit Excel" buttons on it. Can anyone tell me the name of the object for this control so that I can make it invisible?
