View 5 RepliesI 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.

My workplace has access to Excell VBA only.
This is my macro for the Excel userform:

I 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.
I need some code which checks if excel is open or not, if excel is not open then opens it (that code is fine)

I 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".

I have done some code to write to Excel from a String Array of 3 items. These 3 items are written to columns 1, 2, 17 or 3, 4, 17, depending on the value of the 3rd item in the array. For certain Excel files, this is taking too long to write. Is it because I'm writing cell by cell? Is there any other way of writing faster to Excel?
