I created a dataset and connected it to my Data Grid but the number of columns and names of them are not flexible and don't change according new statistical reports that would be available in my table.Is there any way to update my dataset and recreate it according to my new information in my table and show it correctly with Data Grid?

I apologize if it is not. I am trying to write a script in Visual Studio 2008 (using a VB project) that will, upon the clicking of a button:
- A file object will be created.
-Said file object will read in a number of files from a specified file path.
-A dataset will be created and populated with fields from two columns within a database table; app_id and company_name.
-The script will read through the file names and fields recorded in the dataset, renaming the file to the app_id if the original file name contained the company_name.
The code I have so far to do this:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
'Create the file object
Dim objFSO
The problem is that currently this code will only rename the file if the file name and company_name match exactly, ideally I'd need to include a clause to make it rename if the file name is "LIKE" or "contains" the company_name.

I am having issues understanding why it is that a text box that has been bound to a dataset correctly updates that dataset when the text in the box is manually changed i.e. by changing it using the keyboard but the dataset does not recognise the change when I change it in code.Am I missing something obvious? The text is changed in code when the user clicks on a command button that copies the text from another textbox on the form to this textbox.
[Code]...
As i mentioned, manually it works fine but when I use the comman button to change the text it does not recognise that any changes have occured.

I have a bindingsource question, didn't know if anyone had run into this before, but,there are several textboxes I put on a form, the text of each textbox is bound to a field in a table from the bindingsource. Why is it when I update the tableadapter, some of the fields update and some of them don't?
Example:
using the bindingsource
Textbox1.Text is bound to UnitListBindingSource - UnitNumber

Assume my form has four text boxes and it's bond with a Dataset, therefore The user can 1-4 fields. Typically I write one update statement that take four input parameters. Therefore I update the updated fields as well as non updated field. To do this in the proper way, how many update statements I have to write?
Or
How do I do this update properly? I use SQL server 2K5

I have been tasked with writing a program for our yearly reviews. We want all of the information gathered in the form to be submitted to an access database. I have created the form and the database. I can send info to the database but it is put on a new line everytime it is submitted. I would like to check the first column of the table to see if the user login is already there. If it is there I would like to update the information. If it is not there I would like to create a new row. This seems simple, but I can not figure out how to see if the user login is already there.[code]...

I've been running into some errors with converting strings to dates in the following code. I have recently added the intcall.Value = DateTime.Parse(txtIntCallDate.Text) function which had gotten rid of the error message, however the records are not being updated, any of them on the form. Prior to this the strings were being updated just fine. As long as there is a date entered on the form there is no error, if it's left blank i get the "Problem converting string to datetime"

I am making a booking system. I am using same form for insertion and updation. How can I update by taking the values from the textboxes. For example if the user enters value for just 2 out of 8 fields then How can i update just 2 fields without affecting the rest of the record. I mean to say that if I use a single update query using all the fields then if some textbox is left empty then it will replace the database field value by null or something else.

I'm trying to insert a couple of fields into a csv config file and then update all other rows in the file at the same index by copying the previous 2 entries. I'm reading through each row and converting the row into a list(of String) because it seems to be the most flexible way. Ine initial insert works fine, but the code below doesn't. The actual insert code is:
[Code]...
pcIndex is the list index value from elsewhere in the code at the insertion of the 1st of a pair of values into one row. I need to update that index point and pcIndex +1 in all other rows. However it's not doing anything. Tried using lstSteps.Insert, InsertRange, etc. Am I using this right? Is there a better way? It seems to be over-writing the entry rather than inserting a new column and moving the others up, so it appears the list capacity value isn't updating - so I'm left with the initial row with 4 more entries than the others sticking out of the file.

Today i have been checking out the concept of datasets and i like the way they work except for a minor issue i have with it.The following code should get a databasetable and put it in a dataset and return that set to the user.[code]I submit the table name and it will select it, read it and fill the dataset with it, then return it. And it does exactly that once.If i try to re-read the same datatable it just returns the exact same dataset as the first time yet i am 100000% sure that i changed it .
