im having an issue with some files we created in the older versions of excell coming in with the controls in the file having upside down text. i found a fix involving converting the file to a .zip and then deleting some "flip:y" instances but i have thousands of files so i need to automate it. im looking for a way to convert the .xls file to the compatable .xlsx version without using Excel.
View 1 RepliesMy application generates XLSX files based on a users requirements.
After the XLSX file is generated the user is redirected to where the file is saved using Response.Redirect...
Response.Redirect("filename.xlsx")
When the user then opens the file... they recieve this message.
The file you are trying to open, 'filename.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?
As a temporary fix I've instructed my users to press "Yes" when they receive this message and the file opens perfectly fine.

View 2 RepliesI've built a simple library to import data from XLS/XLSX files. The code runs perfectly in my WinForms app but occasionally throws exceptions when I run it from ASP.Net. The "occasional" part seems to based on file size. My test file is about 16,000 rows and 18 columns totaling about 4MB as an XLSX file. If I drop rows (down to about 12,000) it works or if I drop columns (down to about 12) it works or certain combinations of these (14,000x14, etc) it works. This leads me to believe that I'm possibly running into a memory constraint somewhere. Below is the distilled code that's not working:
Dim dsn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=""c: est.xlsx"";Extended Properties=Excel 12.0"
Using Con As New System.Data.OleDb.OleDbConnection(dsn)
Con.Open()'Exception thrown here
Con.Close()
End Using
The exception that I'm getting is:External table is not in the expected format Searches for this all talk about getting the DSN correct and since it works on the desktop I know I've got that right.My test machine is a Windows 7 64-bit with the Microsoft Access Database Engine 2010 Redistributable - 32 bit installed. (My machine has Office 2010 32 bit installed which is why I have the 32-bit ADE installed, it won't let you install 64-bit.) I've set my IIS app pool to allow 32-bit applications which I needed to get ADE to work in the first place. I'm running the v4 Framework and as far as I know my IIS settings are pretty much standard.Like I said, the code works every time when I run it through a WinForms app but occasionally fails through ASP.net on the same machine.

I used Visual Studio 2005. It works well when testing, but when I publish it got error: Microsoft Office Excel cannot access the file 'D:OfficeStationaryV0.2ReportTMPReportItem.xlsx'. 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.
my following code is:
Dim ExcelApp
As New Excel.Application
Dim xlWorkBook

Question: How do I programmatically determine which provider to use (Microsoft.Jet.OLEDB.4.0 vs Microsoft.ACE.OLEDB.12.0) when my app runs as a 32-bit process on a machine with Office x64 installed?
I'm developing a VB.net WinForms app in VS 2010 and targeting both x86 and x64.The app processes data from xls, xlsx, mdb and accdb files using System.Data.OleDb:Dim oConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=...")
The x64 version of the program works as expected. The x86 version works as expected on a system with Office x86.When I run the x86 version on a machine with Office 2010 x64, I get the following exception when trying to open a connection:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.I believe this is because I'm running Office 2010 x64 so the x86 data access components are not installed.I can get it to work for Office 2003 files (*.mdb and *.xls) by changing the provider to Microsoft.Jet.OLEDB.4.0.
How do I figure out which provider to use when running as a 32-bit process on a machine with Office x64 installed?Ideally, I'd like a function:If ProviderIsAvailableFor("Microsoft.ACE.OLEDB.12.0") Then
Else If ProviderIsAvailableFor("Microsoft.JET.OLEDB.4.0") Then
I have an excel file that I would like to load into my form and display there.
