View 18 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.
Does anyone have any ideas why IE6 is trying to open an XLSX file as an XLS?
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.

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?
View 4 RepliesI'm using VB.NET 2005 RC and I have built a custom component which consists of a search screen, data grid, dataset etc. The whole project is designed to be imported in to any new application as a custom control which can then be programmatically changed via its methods, events etc. When I tried to import the .dll in to a new windows forms project all the extra stuff contained in my project was also magically imported (such as the dataset I had used, the SQL connection) etc.I have set these their modifier to be private but still they are imported.
What can I do so when a developer imports this custom control in to their toolbox for use, only the control is shown? Otherwise it looks a bit weird to have access to the dataset I'm using with access to the dataset I'm using within the control.
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 got a graphic that I got to rotate about a specific point. So, I got to define the centerX and centerY, the point about which to rotate. For that, I am importing the namespace: "system.windows.media.rotatetransform"The following problem then arises when the above namespace gets underlined with a green curly line and when I place the mouse over it, the following message is displayed:"Namespace or type specified in the Imports'System.Windows.media.rotatetransform' doesn't contain any public member or cannot be found. Make sure the namespae or type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."
View 4 RepliesI 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 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?

trying to input a text file that's tab delimited that looks something like this.
2.2 5.6
3.7 9
1.2 9.1
[code].....
I'm trying to import a tab delimited file into a table.The issue is, SOMETIMES, the file will include an awkward record that has two "null values" and causes my program to throw a "unexpected end of file".For example, each record will have 20 fields. But the last record will have only two fields (two null values), and hence, unexpected EOF.
Currently I'm using a StreamReader. I've tried counting the lines and telling bcp to stop reading before the "phantom nulls", but StreamReader gets an incorrect count of lines due to the "phantom nulls".I've tried the following code to get rid of all bogus code (code borrowed off the net). But it just replaces the fields with empty spaces (I'd like the result of no line left behind).
Public Sub RemoveBlankRowsFromCVSFile2(ByVal filepath As String)
If filepath = DBNull.Value.ToString() Or filepath.Length = 0 Then Throw New ArgumentNullException("filepath")
If (File.Exists(filepath) = False) Then Throw New FileNotFoundException("Could not find CSV file.", filepath)
[code]....
I've tried using SSIS, but it encounters the EOF unexpected error.
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 have a vb system and I wish to execute some code depending on the result of a text box. The text box could contain two strings, depending on the result I want to execute a set of rules to search for specific files e.g. if one option the code will search for certain files defined for example request.doc and if other option then it will search for other files, which are my rules for the searches. I want these rules to be external to the system and for them to be loaded in so that its easier for the user of the system to change these rules if needed so they dont have to go into the programming of the code. Is there a specific file I can use such as .xml or a just a basic .txt file and what would the syntax be for these?
