Reading Excel Into DataGridView And Typing The Data Columns VB 2010?
Sep 5, 2011In my application I read data (using data binding) from an Excel spreadsheet into a DataGridView. This works, but the data columns contain text fields (strings). I would like to set the data type for some columns to "Date" and Decimal. I cant do this on the DataGridView (error: cant change properties for data-bound stuff) and I cant figure out how to do it on the dataset or data-table that I bind to the DataGridView.The following is the code I use to read and bind the data:
Using con As OleDbConnection = New OleDbConnection(cs)
'
'open the OleDbConnection
[code]....
The commented out code (below the 'Todo: comment) causes a additional table, but I want to change the table with the data.

Visual Basic 2008: Reading From Textfile Into Array And Then Presented In Listbox?
Jan 7, 2012I've got the following txt file:
[code]...
Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
