Reading In Data From One Excel File Write That Data To A Different Excel File?
Sep 28, 2011I am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.

How To Write To Excel
Jul 10, 2011I have imported a sheet from Excel. It grabs the first row as the column names saves it in a dataset, and displays it in a grid view.
here is my code to do so:
Try
'Dim MyConnection As System.Data.OleDb.OleDbConnection
Dim DtSet As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The gridview is editable, so when the user edits a cell I want to have a button so they can save the new values back to the excel sheet.
The code above cant be that dissimilar for writing from a dataset instead of reading to, but cant work it out.I want to keep the same Column headings.
Asp.net Using Oledb To Export Excel File Returns Empty Excel File
Feb 24, 2010I 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.

Generalized Write Of Data To Excel?
Mar 14, 2011I need to create an excel file from scratch in VB.NET given a DataTable from asp.net. I can do this for a specific file, but I don't know how to do it for a general database. That is, where I use the "CREATE TABLE ..." I don't know how to tell it what types to use for the data in the table.
The DataTable is derived from a FoxPro database. (I don't know if that matters.)
I invoke the table similar to as follows:
<%
return_value = make_excel( sql_table, excel_filename)
%>
[Code].....
What I need to be able to do is run through the values in sqlTable above, check their type and then build the sql to write them.

Jun 22, 2011I have an excel database with one column and thousands of rows of "number" data. I need to import the data into my form read the first entry, run an algorithm then move the result to the second column then move to the second entry and so on. I am having issues with where to begin. I am able to convert the excel database to a text file if it makes it easier.The algorithm that needs to be ran consists of reading each character one at a time and is as follows:ENTRY example: 12358458754The characters 1,3,8,5,7,4 need to be summed then multiplied by 3. These are all the characters starting with the first one and skipping every other one. I will call them "odds" (not referring to numeric value)The characters that are skipped, I will call them "evens", need to be summed together then added to the result of "odds".
