I mean, my sysadmin does not want us installing Excel on the server and, as I have been searching for some alternatives, I can not find one.
My question is: is there a way to put the necessary dlls in the server without installing Excel or the Office suite?

I know the easy solution would be to create a database table for each particula form and also an ASP.net page for each form.
But then there are problems like printing and correct formating so it fits on the page, spaning multiple pages and so on.
And also is there any advice on how to write to PDF straight from the page?
I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet. If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown. A test program in windows form is also working fine regardless of how many rows.
Code has been simplified, "information ..." in the sql insertion command represents 1803 characters.
ExcelObjConn = "Provider=Microsoft.Ace.OLEDB.12.0;" & _
"Data Source=" & fileName & ";Extended Properties=Excel 12.0 XML"
ExcelConnection = New System.Data.OleDb.OleDbConnection(ExcelObjConn)
ExcelConnection.Open()
Try
SqlCommand = "CREATE TABLE ABC ([row1] text, [row2] text, [row3] text, [row4] text)"
ExcelCommand = New OleDb.OleDbCommand(SqlCommand, ExcelConnection)
ExcelCommand.ExecuteNonQuery()
ExcelCommand.Dispose()
For i As Integer = 0 To 1124
SqlCommand = "Insert into ABC ([row1], [row2], [row3], [row4]) Values ('information...', 'information ...', 'information ...', 'information ...')"
ExcelCommand = New OleDb.OleDbCommand(SqlCommand, ExcelConnection)
ExcelCommand.ExecuteNonQuery()
ExcelCommand.Dispose()
Next
Catch ex As Exception
Finally
If ExcelConnection IsNot Nothing Then
ExcelConnection.Close()
ExcelConnection.Dispose()
End If
End Try
I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.
I have created an excel sheet from datatable using function. I want to read the excel sheet programatically using the below connectionstring. This string works fine for all other excel sheets but not for the one i created using the function. I guess it is because of excel version problem.
OleDbConnection conn= new OleDbConnection("Data Source='" + path +"';provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=Excel 8.0;";);
which i can create an excel sheet such that it is readable again using above query. I cannot use Microsoft InterOp library as it is not supported by my host. I have even changed different encoding formats. Still it doesnt work

View 2 RepliesI have an asp.net application. I want to add a global.asax and global.asax.cs file to my project. In the IDE when I select to create a new global.asax file, the option to create a CS code behind file is greyed out. When the global.asax file is created, no code behind is created, instead code is placed in the global.asax file and the global.asax.cs file is never created? Why is the option for a C# code behind file greyed out?
