View 4 RepliesReading A Blank String From Excel When Trying To Read The Header Of A Data Column?
Aug 25, 2011I use an OLEDB connection to read from an excel database, and this loop to read in all of the data from each of the columns
While reader.Read()
For i As Integer = 0 To reader.FieldCount - 1
temp = reader(i).ToString + ControlChars.Tab
output_file.Write(temp)
[code]....
Some of the columns contain date information, which are read in fine (usually as a string "2/20/2011" or so), but the headers of those columns are read in as a blank "". The headers for all the other columns read in fine, but not for the date containing columns.

VS 2010 How To Excel Read/write
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".

VS 2010 Read A Sheet From A Excel Workbook And Pop It Into A Datatable?
Oct 14, 2010I have managed to read a sheet from a excel workbook and pop it into a datatable.
Public Function GetSheet(ByVal SheetName As String) As DataTable
Try
MyDataTable.Clear()
[Code]....
My understanding is that if I make changes in the datagridview it is reflected in the datatable.
So now I want to write the updated datatable back to the appropriate worksheet.
I have read about "insert into" or "update" etc but it is very specific columns and rows.
One other thing, when I set the datagridview datasource as the datatable I get about 9 other columns such as TABLE_SCHEMA TABLE_TYPE etc. Any pointers wher thay are coming from and maybe how to get rid ofthem?
VS 2010 Populate Textbox With Excel Data Based On Combobox Selection?
Nov 29, 2011Visual Basic 2010 Express: I have a form with a combobox that is populated with the names of locations from a datagrid which in turn was imported at run-time (Form_Load) from an Excel database. The Excel database (and the datagrid) also stores the information for addresses and phone numbers for their respective locations.
What I would like to do is have the phone number and address text boxes automatically be updated with the proper corresponding data when the user selects a location from the combobox. Whether the text boxes are updated from the datagrid or Excel database is not a concern; I'm mainly looking for whichever way is simpler.
