May 31, 2010have a tab delimited text file, which I'm reading into a datatable and showing in a grid.I see that I can't update the text file with any changes made to the data, using an UPDATE command. So how would I go about doing this?I could write out the datatable to a new text file, this is not a problem. But I'm only retrieving X records from the text file, so the datatable won't hold the entire text file.

VS 2008 Read Csv File Into Dgv - Text Versus Numeric Values?
Oct 13, 2010I read a csv file into my .net program using ado.net and display it in a datagridview.In the file I have two rows. The first column is a component id, and it is supposed to be numeric. But the user can edit the csv file before having my program load it, and accidentally put text there. That is something I want to edit when he presses a button to add the data to the database. So let's say he puts a value of A in the first record and a value of 1 in the second record. Or vice versa. What is displayed in the dgv is a blank in the first record and a 1 in the second, or 1 in first and blank in second. If both csv records are A, then what is displayed in the dgv is an A in both the first and second records. I don't understand what is happening. The fact that there sometimes is a numeric in the column makes it think it is a numeric field and therefore only display numerics and blank otherwise, and the fact that there's always text in the column makes the code know it is a text field?

Aug 17, 2011I have two data tables. dtAllResults is the master data table which contains ResultIDs and everything related to each ResultID. dtNoCV is the other data table which only contains ResultIDs. If the ResultID from dtNoCV is located in dtAllResults I want to update some checkbox cells in dtAllResults (as seen below).
I'm looking for better performance, because dtNoCV may contain a few hundred ResultIDs and I'm afraid this loop will slow things down.

View 5 RepliesUpdate Access DB With Passed In Values?
Mar 11, 2010I am currently working on a project that requires an update within an Access Database. There are photo folders, and the user defines the path name via a dialog box. That path name is stored to a string value, and through OleDBReader, the actual name of the photo (from another column in the database) is stored to another string value. Anyway, I have tried a number of methods to update, and nothing is working, here is my code from the OleDBReader on, and the procedure designed to do the update. (note that TargetID represents the primary key of the access DB.. this is why I pass that value in because I can use the Rows.Find(PK) method.. When I use a simpler updating method, I get an error saying I do not have a valid update command). OK Here is the code:
Dim photoSQL As String = "SELECT * FROM PotentialTarget"
Dim oleDbCommand As OleDbCommand = New OleDbCommand(photoSQL, tableConn)
Dim oleDbDataReader As OleDbDataReader = oleDbCommand.ExecuteReader()

(VB2010) Save The Values To A File Which Loads The Values In The Specified Labels On Startup?
Jun 2, 2011lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?
