Export DataSet To Existing Excel Worksheet
Nov 4, 2010VB2005. I have several DataSets that I create or grab from an external source. One example is
Dim sql As String = "SELECT TOP 30 * FROM myTable" & vbCrLf & _
"WHERE Area='YY' AND CarNum='734EP' " & _
"ORDER BY ProcDate ASC;"
Dim da As New OleDbDataAdapter(sql, myOLEDBconn)
'create a dataset and fill it with the returned data.
Dim ds As New DataSet
da.Fill(ds, "MyData")
Once I have these DataSets I then have to pump them into a specific worksheet in an existing Excel2007 workbook. The connection and interaction with Excel and the workbook/worksheet is already established and that works. But I am stuck in exporting the DataSets
into the specific worksheet.
Note that I have already scoured the web and MS Community site and all code that I have found so far iterates through each and every row and column of the DataSet and then adds that to the worksheet in a cell by cell manner. This is fine and in testing that works. But there has got to be a better way to do this. For even a moderate sized DataSet the exporting just takes a long time. 25 records with 15 columns takes about 10 to 15 seconds.
I've also been experimenting with some scratch code I found that converts the DataSet to an ADODB Recordset and then uses the xlwksht.Cells.CopyFromRecordset function to export it in one fell swoop. I haven't got this one to work just right but it seems in the end it also does an iteration through each and every record and field to convert to the ADODB recordset.
VS 2005 Append Data To Existing Worksheet?
Mar 5, 2011I have worked out all the other bugs in my Staffing app. A while back .paul helped me with exporting my data to excel. So what I need to do now is this:
Schedule AM RN's and export to excel DONE
Schedule PM RN's and export to excel appending to existing worksheet
Schedule AM NT's and export to excel appending to existing worksheet
Schedule PM NT's and export to excel appending to existing worksheet
Schedule AM WC's and export to excel appending to existing worksheet
Schedule PM WC's and export to excel appending to existing worksheet
I only need 1 workbook, and each new full schedule will be a new worksheet with the beginning date/ending date as the worksheet name.

Writing Data To An Existing Excel File?
Mar 15, 2010I'm working on a project where I have to allow users to write data to an existing Excel worksheet (by entering the data into a form created in Visual Basic.NET). I've created a form that allows users to enter data such as the following:
Name (First, Last)
Mailing Address
Email Address
Gender
Age
...and so on. I've programmed the data to be sent to the Excel file upon clicking on the Submit button in the form itself. I've also created the Excel file and placed it on my C: drive, but the problem I'm having is trying to send the data from the VB form to the Excel file itself. Can someone please show me some sample code or point me in the right direction as to how to get the submitted information from the form to save into the Excel file, please?
I'm trying to get the information to show up in rows and columns in Excel like the following below (the dashes are just to show that the information should be in rows and columns):

John Doe---------------------2300 Jackson Street-------- xxx@xxxx.com-------Male---------17
