IE6 Opening XLSX File As An XLS?
Jul 14, 2010
My 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.
Does anyone have any ideas why IE6 is trying to open an XLSX file as an XLS?

I'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 have used the Process.start function to open an Excel file as shown in the code
Process.Start("report.xlsx") and it works perfectly well.
My question is can this function be used to open a particular worksheet called Report1 in the report.xlsx file. If so what would the code be.I have spent many hours trying to research this topic but without success.

I use the followoing code to import an xlsx file into an Access 2007 table. It works fine when I enter the exact file name.However, part of the file name is a date which will change every week.The file location does not change,just the date in the file name.[code]I've tried using a wildcard but I get a Run-time error 3011.Db engine could not find the object. Make sure the object exists.

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
As Excel.Workbook

I have been able to export data from a query to the xlsx file..howerver those fields which are currency in my sql server 2005 table are currency are showing up in the spreadsheet as text. The column mappings are correct when I look at it in connection manager.
Also Is there also a way to create a new worksheet each time the export is run or does the file have to be already named?

I have a program that can save user's input into a text file and load it back, but whenever I try to open the file and exit without selecting the file I get an error.(if i select the file and open it i don't get any errors).
This is the code that handles text file loading:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
OpenFileDialog1.InitialDirectory = "C:"
OpenFileDialog1.Filter = "Text Files ONLY (*.txt) | *.txt"
OpenFileDialog1.ShowDialog()
[CODE]...
The error is :"FileNotFoundException was unhandled. Could not find file at xxx". also I would like to know how to make it so that the initial file name for file saving is today's date. I do not get any errors when I try to save the file.

I need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.

I'm having a slight problem getting my program to load a save file when double clicking the save file.I'm using the Command$() to get the command line argument. I can open a save file by dragging it onto the exe. But not by double clicking the save file (after it's associated with the exe).I though dragging and dropping a file on a program and double clicking the file would open it in the same way, but I guess not.So in short how does file association work and how do I get the file path set to a var when the program loads.

I got a log file (Log.txt) a timer and a RichTextBox1.Text The timer is opening the log file again and again every milisecond here the code:
Code:
Okay that keeps the track of my log file inside my richtextbox , but there is a big problem there. My richtextbox slows down hard if the log file gets too big.. Sometimes it kicks me out of the program and in taskbar it says Program Not Responding..
I wanted to know if there is a method to read a bigger Log file with out having such issues. (It mostly happens when log file goes over 13000 characters)

I am using VB.net 2005 and I have a timer running on form1 that communicates modbus with a relay io board. There should be constant uninterrupted communication between the two devices and that is working until I open the data logging form2 and import data from a large sequential text file. While I am parsing data, the timer from form1 stops communicating with the modbus device. Once the data is done, the timer of form1 resumes communication with the modbus device. Is there some other method I could use to make sure the modbus communication is never interrupted.? Is there a command I can periodically run from form2 while the data is being parsed that will keep the timer on form1running?

My program performs a search on a specific directory and returns a list of files with specific criteria. When the user selects a file name in the list box and Clicks the button, I want the program to open that file and print it. I have two functions - one store the file path in a text box and the other gives me an option to select the printer. have no idea how to open the file using that path and how to get it print.If i specify the hard code the a specific file path, it currently can open all files except a .dwg file. For a .dwg file, my program opens auto-cad and crashes?

I am developing an Excel workbook at work and I've got a problem. I'd like to save information entered in the workbook and save it in another one (called List, for example purposes), using a macro. The problem is that the file in which I want to save the information is located on a server. When people open List.xls, it's Read Only. So, when my macro executes, it opens a Read Only workbook...I'd like to do "Open As", just like you could do by right-clicking on any file in Windows XP. The result would be that the macro would log on as administrator only to open List.xls, write in it and save it under the same name.
