Will Upgrading Office From 2003 To 2007 Break VB Programs Which Use Excel Through COM Interop?
Mar 31, 2009
Assume all traces of Office 2003 will be removed from the computer.I understand that I will still be able to use .xls files. I'm asking about automating Excel through the COM interop from outside Excel. When I add a reference to Excel to a VB project, it gives me a different version of the dll for different versions of Excel. If a program was compiled with a reference to Office 2003's dll, will it need to be recompiled for Office 2007? Will the code need to be updated to use the new dll?

I have a .NET winforms app that automates Excel and checks for a worksheet password. The requirements are to be able to detect
1) that the protection is turned off
2) that the password is removed (protected but there is no password)
3) that the password matches the correct password from a database
To meet the second requirement the program calls the Worksheet.Unprotect command with a null string, capturing the error. If error as expected, the 3rd check is made. If no error, then the Unprotect worked without a password ==> password was removed.
The code sample below has these checks.The application can do this fine with Office 2003. I have since had my dev machine updated to Office 2007 and it no longer works as it did. When I call the Worksheet.Unprotect, Excel prompts for the password!
I need to know how this should be accomplished in the new version of Excel or if there is a way to reference the old PIA. No matter what if I set a reference to Excel 11 it is replaced with the PIA for 12 in the GAC.
'return true if unprotect of worksheet does not generate an error
'all other errors will bubble up
'return false if specific error is "Password is invalid..."

I have both Excel 2003 and Excel 2007 installed on my system. When I call oExcel = CreateObject("Excel.Application"), Excel 2003 is used in the context in my .NET code instead of Excel 2007 (which I need to be used). I have referenced the "Microsoft Excel 12.0 Object Library" but when the code runs, the 11.0 version is used.
Is it because I am using Visual Studio .Net 2003 that Excel 2007 cannot be correctly referenced or do I need to change a reference or setting?

We have currently upgraded our development machines to Windows 7 and Office 2007. We have a vb 2008 app that references 2003 Office components to use for mail-merging to word.We loaded up our app in the vb environment today and were instantly greeted with missing components/functions which are related to the 2003 Office components. We can update these to use the Office 2007 components/functions instead, however we are unsure whether after doing this our vb app will work with machines only with Office 2003 on. can machines with Office 2003 on work with our vb app that references Office 2007 components?

I Am about to buy a new office, and I must decide between 2007 and 2003.
I'd like to buy 2007 (same price where I live) but I cannot stand the UI.
Is there a way to make it look like 2003 (for me Word/Excel is enough) ?

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

I am designing a shared add-in using VB.Net 2008 and VSTO that has to fire up when any MS Office App is started. It has to work for both 2002, 2003 and 2007 applications. I have managed to put together a working add-in that pops up a test message stating the version of Office and the Application name and tested this across all the apps ok.
The next part of the solution is to code the application specific code that needs to run for document auditing and corporate protective marking as well as, for example; in Excel checking that all the Add-Ins are linked to the Network Add-Ins folder.
My approach from now was going to be to late bind against the application object and set one of my typed (e.g. Excel) application object references which exist in the code to this object.

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.

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.

have a Visual Basic 2008 project with references to Microsoft.Office.Interop.Excel and Microsoft.Office.Interop.Access for Office 12/Office 2007. I also have Office 2007 installed on my PC. I tried running my program on a PC which has Office 2003installed (i installed the compatibility pack to open .xlsx files) and the Access Database Engine for .accdb Databases.It does not have VS2008 installed but has .Net Framework 3.5 SP1 installed.

I am writing a function to export data to Excel using the Office Interop in VB .NET. I am currently writing the cells directly using the Excel worksheet's Cells() method:
worksheet.Cells(rowIndex, colIndex) = data(rowIndex)(colIndex)
This is taking a long time for large amounts of data. Is there a faster way to write a lot of data to Excel at once?

how I can use excel 2003 and excel 2007 on my application. I add a reference to Excel 12.0 Object but this one is not compatible with Excel 2007 and i think if i add Excel 11 Object it will not run on excel 2007.
Is there any solution that I can use so that my project can be used with either excel 2003 and 2007?

I've a windows form application which opens an Excel file and do some actions and save it as another file. All this is working perfect in windows forms. When I copy the same code and paste it in a windows service, then it is not possible to open the file even.

I have a program that reads data from excel.
I use:Imports Microsoft.Office.Interop as well as a Reference from the "COM" tab called "Microsoft Excel 11.0 Object Library"
I built my program then copied the .exe from the inDebug folder to a location on my company's server. I then double clicked the .exe and it ran as I expected it would.My boss then tried (from another computer) and he gets this error:See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

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)
