I need to convert a excel file to pdf file in asp.net. How to achieve this in c#.
View 1 RepliesIv created a web application using vb.net 2005. Its working fine and running fine on the server (Microsoft Server 2003). The problem i have is to dowload a file from the same server using vb.net. I tried using this code but it gives me a : "is not a virtual path" error.
Response.ContentType =
"file/xlsx"
Response.AppendHeader(
Response.TransmitFile(
Response.End()
"Content-Disposition",
"attachment; filename=AllReports.xlsx")".xlsx")
While exporting the html to Excel using Response.Write() in ASP.NET and when I try to save as the exported file I'm getting the default save as file type 'Web Page *.html, *.htm in excel application. Is there an any fix to get the default save as file type as xls or xlsx?
View 6 RepliesIn my application I've allowed users to upload Excel 2003 .xls files, and import them into a Gridview. This has been working fine using the following connection string:
[Code]....
Now my users are using Excel 2003, 2007 or 2010, I need to allow the newer file extensions (.XLSX) to be accessible too.
Therefore, within the connection string above I presume I could change the Excel version from 8.0 to 9.0 or 10.0 respectively, but is there much difference between Excel 2007 and Excel 2010 files?
If so, is it possible to 'detect' the Excel file version so that I can use the appropriate connection string to read the data from the files?
I get the following error message:
Could not find file 'C:CHURCHROOF - CRIME live 150110.xlsx'.
When running the following code:
if (FileUpLoad1.HasFile)
{
string serverpath = "\\server1\Temp\ ";
//top.window.close();
string filepath = FileUpLoad1.PostedFile.FileName;
string filename = FileUpLoad1.FileName;
string destination = serverpath + filename;
//File.Delete(destination);
string[] existingFilesArray = System.IO.Directory.GetFiles(serverpath, "*.xlsx");
foreach (string existingFile in existingFilesArray)
{
System.IO.File.Delete(existingFile);
}
File.Copy(filepath, destination);
}
The code looks for a file and uploads the file to another location.
it fails at the last section
It works for me on my machine. but not the users
File.Copy(filepath, destination);
NO matter were the users put the file it fails.
how can i write a sql to execute the file at specific time sql server database.

When I try to edit the Identity Specification from No to Yes there isn't a way to do so. No drop-down arrow or any way to edit the text. How can I change it so that I can actually change the value to 'Yes'?
View 2 RepliesI'm working on some code that generates an Excel spreadsheet server-side and then downloads it to the user. I'm using ExcelPackage to generate the file.
The generation is working just fine. I can open the generated files using Excel 2007 with no issues. But, I'm having trouble downloading the file with Response.TransmitFile().
Right now, I have the following code:
//Generate the file using ExcelPackage
string fileName = generateExcelFile(dataList, "MyReportData");
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.ContentType = "application/vnd.xls"
Response.Charset = "";
Response.TransmitFile(fileName);
When Excel 2007 opens the file downloaded as above, it gives the "file format doesn't match extension" warning. After clicking past the warning, Excel displays the raw xml contents of the file. If I change the file extension, like so Response.AddHeader("content-disposition", "attachment;filename=FileName.xlsx");
Excel 2007 gives an "Excel found unreadable content in the file" error, followed by a dialog that offers to locate a converter on the web. If I click "no" on this dialog, Excel is able to load the data.
I've also experimented with different MIME types, like application/vnd.ms-excel and application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, combined with file extensions of .xls and .xlsx. All combinations result in one of the two behaviors mentioned above. What is the correct combination of file extension and MIME type to use in this scenario? What else could cause this failure, other than an improper MIME type or extension? FYI, this is occurring with Visual Studio's built-in development web server. I haven't yet tried this with IIS.
I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names.So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.
View 3 RepliesI have a link http://Test/Folder/file1.xls which is working fine But if I typehttp://Test/Folder/file1.xlsx it is not working. It is giving me a file not found error.So when I read online every one is suggesting me to add the correct MIME type at tyhe IIS level. I don't know if that's the correct thing to do.I opened IIS and navigated to folder FOLDER right clicked and selected properties -> HTTP Headers -> MIME Types->New -> Extension -> .Xlsx-> What should i be entering for MIME type?

View 2 RepliesUsing the Interop for Excel 2003 I had a nice little link that saved or opened the repeater content as .xls. Now we are using Excel 2007 and I get file format error messages. When I click the OK button on the error pop-up Excel closes. Does anyone out there know how to convert my code to handle the .xlsx format? I've been reading up on Interop for 2007 but none of the examples seem to work for this particular simple task. Here is my code from the "Export to Excel" button click:
Protected Sub btnExport_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExport.Click
' Send HTTP headers that specify Excel filename, MIME type, and character set
Dim sTemp As String = "attachment;filename=CoverageCase" & Session("OpenCase").casekey.ToString & ".xlsx"
Response.AddHeader("content-disposition", sTemp)
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""

View 1 RepliesI'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.
