VS 2008 : Using SQL Query And Excel File?

Nov 15, 2011

I'm retrieving data from an Excel sheet, using a simple SQL query using a textbox as input to my variable. It works great when I enter an integer to search for (such as 213 for example) but when I put in a mixture of numbers and letters (48A for example) I get the following error: Syntax error (missing operator) in query expression '[P&L]=48A'. Can anyone tell me the fix for this? I know it has something somewhere to do with integers.

Private Sub MPLS3()
Dim BrNr As String
BrNr = TextBox1.Text

How To Create An Excel File Using A Database Query

Mar 28, 2011

I would like to generate an Excel file using a database query in VB.Net. How can I do it? To be more precise: I would like to "bind" a query (much like binding a query to a GridView) to an Excel file such that the rows in the table occupy corresponding cells in a new Excel file, and save the file to my computer. And then, mail that file to someone. While I can handle the mailing part, it's the creation of such a file that I need help with. Anyone know how to achieve what I want to achieve? PS: I need to do this in VB.Net and I'm using SQL Server 2008.

Asp.net Using Oledb To Export Excel File Returns Empty Excel File

Feb 24, 2010

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]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.

VS 2008 - Getting Every Bit Of Data From Excel File

Nov 2, 2009

I need to get ALL data from an excel file.. for some reason I can not get the data that is like this.
column C:
2122
2122-215
2133CD
2441
I can get all the green just fine. but the red I can not.

Here's my code for extracting the data.
vb.net
Do While rsRecords.Read
RichTextBox1.Text += vbCrLf
For intFields As Integer = 0 To rsRecords.FieldCount - 1
If Not rsRecords.IsDBNull(intFields) = 1 Then
RichTextBox1.Text += rsRecords.GetValue(intFields) & Space(5) '.GetValue(intFields))
End If
Next
Loop

Here's the full subroutine. Keep in mind this does pull data. Just not from the same column that contains actual numbers where there are not actual numbers.
vb.net
Private Sub NewFileToolStripMenuItem_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles NewFileToolStripMenuItem.Click
Dim dbConnection As New cADOConnection("C:Documents and Settings<user>DesktopAttribute data Line 2.xls")
Dim rsRecords As OleDb.OleDbDataReader = Nothing

VS 2008 - Creating / Saving Excel File In BGW

Jun 4, 2011

I am trying to use the BGW to save a DGV to excel file, but don't know how to do it correctly, specifically setting the savefile name this code doesn't work gives me:

'System.Runtime.InteropServices.COMException' occurred
- Make sure the specified folder exists.
- Make sure the folder that contains the file is not read-only.
- Make sure the file name does not contain any of the following characters:

Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process. I also tried doing the Save in the BGW RunWorker Completed event but then there is no file name. It seems I need to pass the file name the user inputs in the SaveFileDialog to the BWG WorkerCompleted event somehow

Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."

Integrating SQL Query Into Excel?

May 29, 2009

I have a SQL query that I want to integrate into a VBA subroutine in Excel. I have had some success using the Macro Recorder to call up the SQL query (throuh Microsoft Query) in the past. However, the SQL code that I have for this query is significantly larger than previous attempts.When I record this one through the Macro Recorder is trips up because there are too many line breaks integrated into the recorded code. To get around this I have tried to manually update previous (successful) queries with the larger SQL code that I want to use, but without success.I was hoping that someone out there has some experience in integrating the standard SQL query code (SELECT xxxx, yyyy, zzzz, *nnnn FROM aaaa, bbbb, cccc, *nnnn WHERE 1111, 2222, 3333, *nnnn) into VBA.
