I am trying to FTP an .xlsx file. I have to code uploading the file, but it is uploading it in a zip folder. how I can fix this? Is it a setting I am seeting with my code, or is it a setting the the FTP page itself? The code shown below is the code i am using to FTP the file. It was posted to my other thread by bdbodger.
[Code]...
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?
Is there a simple way in vb.net to load an excel file and read it? perhaps there is a way to load the file but have it not be visible to the user?

How do i this?Import data from XLS,XLSX,CSV,XML excel file to .NET?
View 6 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 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.
View 1 RepliesI 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

1. I can't find the file which reflects changes to user settings. This might be because I just can't find it (I can see a bunch of user.config files but they are all empty - weird!), or...
2. I'm not actually saving them when I think I am.
Regarding 2. - do I need to invoke
Is this all I need? And if so, why are my user.configs empty?
I have created a settings-file for my plug-in-based app. When the mainApp writes the settings to the file, the pluginApp should read the settings from the settings-file (when opening or at runtime even better), but somehow it reads the settings from the app.config-file. This means that the pluginApp never will read the settings according the values of the file.
View 4 RepliesI saw that you can also use a "Settings File" (Add new Item)to add your settings instead of the application settings. But I can't seem to write any values to the file. Someone with experience with the "Settings1.settings"?
View 2 RepliesI 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?
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.

I'm looking for a way to specify the location for the User.config file that is used for storing the My.Settings object. It appears that this is not possible. The problem for me is, I don't want to be responsible for creating several different files on the users computer that really have no use and are difficult to find and clean once an update is released. For most users, this is not a serious problem, as many will probably never update the software, and most will probably only go through a couple of updates. On my system, there are config files for every build of the application, and the same to a lesser extent will be true for my beta testers.
I can understand that MS wants to make sure that no two applications will use the same location for storing application data, but a simple [UserData] [CompanyName][ApplicationName] for storing application data will probably suffice for 99.9999 percent of the legitimate applications in the world. Bogging a user's system down with erroneous files, no matter how small, is an unnecessary drain on system resources and a potential source of problems for the user. It's bad enough that most programs leave bits and pieces of themselves all over a user's system after De-installation - this to me seems only to exaggerate this problem.
Is the only way to get around this problem to write a whole new Settings Class? Is there a way to change the location of the UserConfig file to a more friendly (and more predictable) location that I am not finding for myself? It would seem that having at least the OPTION to specify a location for the User.Config file would be OBVIOUS and easy to implement, so why did they leave this out?
give me a code to convert xlsx file to csv using vb code?

I know there are allot of toppics about this subject, but i cannot find really what i need.
i need a file associations with settings.. so when you click for an example: "PC0210.config" it will start my program with some settings inside the "PC0210.config" File.
Lets say my program needs to give a message box with the PC name when you click the PC0210.config file.
that inside the PC0210.config file is something like: pcname="testPC"my program popsup with: testPC
Heres what I need:
1. A way to save settings (Exp.: userkey=randomkey)
2. A way to than read these settings from inside the form.
3. A way to convert settings to strings.
4. A way for users to edit settings
5. No external files.
