Excel File Save In Office 2007 Format?
Mar 1, 2009
I'm developing a small application that creates Excel files with user details. I'm developing this in vb.net 2008 express edition under Windows XP SP2 and with Office 2003.My target PC is running Windows Vista. I'm able to run my program without any problem and even the Excel files get created without any problem on this PC.However, the problem is when I try to open one of these created files in Vista, I get a message like below:
"The file you are trying to open, "TestMe.xls", is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?" If I click yes, it opens up properly. This is a headache as it opens up in my developing PC without any hassle. I'm sure its something to do with the Excel reference I've made in my PC (which is running Office 2003).How best can I save this file so it opens up in Excel 2007 without the above message.

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 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?

I used the code previously added by Mike Rosenblum but Excel is still not closing, Here is my code:
Imports Microsoft.Office.Interop
Imports Excel = Microsoft.Office.Interop.Excel
Imports System.Runtime.InteropServices
Private Sub Check_For_Xcel(ByVal filename As String)
Dim varpath As String = ""
Dim varvalue As String = ""
Dim xlapp As New Excel.Application
Dim xlbook1 As Excel.Workbook = xlapp.Workbooks.Add()
Try
varpath = filename
xlbook1 = GetObject(varpath)
xlbook1.Application.Visible = True
xlbook1.Windows(1).Visible = True
xlbook1.Application.WindowState = Excel.XlWindowState.xlMinimized
For irow = 2 To 65536
For icol = 1 To 4
Select Case icol
Case 1
read_date_time = xlbook1.Worksheets(1).Cells(irow, icol).Value
Case 2
read_plate = xlbook1.Worksheets(1).Cells(irow, icol).Value
Case 3
read_plate_state = xlbook1.Worksheets(1).Cells(irow, icol).Value
Case 4
read_location = xlbook1.Worksheets(1).Cells(irow, icol).Value
End Select
Next
If read_plate = Nothing Then Exit For
Check_IF_Present(read_plate, read_plate_state)
Next
If Not xlapp Is Nothing Then
GC.Collect()
GC.WaitForPendingFinalizers()
GC.Collect()
GC.WaitForPendingFinalizers()
Marshal.FinalReleaseComObject(xlbook1.Worksheets)
xlbook1.Close(SaveChanges:=False)
Marshal.FinalReleaseComObject(xlbook1)
xlapp.Quit()
Marshal.FinalReleaseComObject(xlapp)
End If
xlbook1 = Nothing
xlapp = Nothing
GC.Collect()
GC.WaitForPendingFinalizers()
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Critical, "Error at Check for Xcel")
End Try
End Sub

I've managed to work out how to read EXCEL cells via static values. Ideally I would like my application to check the third column of the EXCEL sheet and if there are no entries on a given row, it should display the coresponding row of colums 1 and 2...for example if (C,3) contains no entry then get values of (A,3) and (B,3)...then mark (C,3) as pending by writing a value to (C,3). Here is my code at the moment

I have an application that browses through Excel-files, changes color in some cells if they are in a wrong format etc.When my application is saving the changed file I get this alert about compatibility issues that can occur, and this alertbox has to be agreed or cancelled to move on to the next file. How can I disable this compatibility check programmatically? Or is there any way to ensure there are only Excel 2003 compatible colors in the document before saving?

I have an issue which has successfully busted my head all weekend. I created a COMAdd-in, in VB.NET (VS 2008) for Excel 2003. We now need to work the solution out for 2007 and since the layout and objects are a little different we had to make some critical Interface changes.Instead of a floating CommandBar we are now going with RibbonBar, which looks good but it doesn't work. Whenever I open Excel Workbook (which is the primary application). The Add-in successfully recognizes it and opens it up properly (bunch of Macro calls, layout settings etc). Anyway, after it opens, if I click on any button (on the new ribbon tab) I get "Application not properly initialize. Program will now close" and excel object is lost.

I have used Visual Studio 2008 (VB) to create a custom tab and button group with custom buttons. When any of those buttons are clicked, I simply want to run a macro (add-in) that will already be loaded when Excel is launched. The main examples I've seen create an Excel object in the VB code and then call the macro, but that seems like unnecessary overhead, since the custom buttons are are already loaded into Excel.

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?

VB.NET code to change Excel 2007 Column Cell Format from Text to a Number no Decimal.
Right now Column F shows values that look like
3E+13
3E+13
Manually changing it to a Number with No Decimal shows the correct value.
30000046605562
30000041582875
Of course I would like to automate this.

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.
Is there a way to write data to Excel format without having Microsoft Office installed?

I have downloaded the official office 2007 UI ribbon .dll, but now what? I am coding in VB.net. I do not know where to place this .dll, and I do not see any additional controls anywhere at all. The readme explains how to license your copy, which I have done.Now what? I am hoping to magically see the ribbon control in the list of components I can add somewhere, but its just not there....Is there even a way to use this as a drag-n-drop component with the WYSIWYG Design View?

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'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'.

How do I unregister an xla file?I one that got registered incorrectly and am having problems getting rid of it.It changes the behavior of all of my excel files, I have to use the ribbon to do insert, delete, copy, paste and when formulas are changed they do not refresh automatically. When you double click on the excel file to open I get the following windows error saying it cannot find the file but it is there. Windows cannot fine C:Users<my name>Documents<shortcut folder name><excel filename> (sk).xls. Make sure you typed the name correctly, and then try again.I used VB to display sheet events and everything appears to have the default values.

how can I let VB.Net writes an excel 2007 file? For example, the data in a TextBox will be written to the excel file every 30 seconds.The enviroment is VS2008, .Net 3.5.I've just started VB for one month, so please give me a piece of code to help me understand. I tried to find the solution on the Internet, but none of the codes worked for me, some people mentioned import "Microsoft.Office.Interop" in the code, but if do that in my code, VS said that "Namespace or type in the Imports 'Microsoft.Office.Interop' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."
