But how i avoid when you selected nothing, you can delete.
This is such a basic question, I'm almost embarassed to ask it. How do I loop through seleted rows in a DataGridView and remove the rows?I've tried this, but it doesn't work. After one row is removed, the index is all screwed up.
[Code]...
What im trying to do is display my details in a listbox then the one that is selected frm the listbox is displayed in the textboxes and when delete button is clicked it is flagged at deleted??? This is what should happen!!:@
I kow there is definitely a problem with this piece of code im setting the index and length to constant numbers so if a different name is clicked it does not work!! is there another way to set this to allow for any length or index position??
CustomerIDTextBox.Text = DisplayCustomersListBox.Text.Substring(0, 4)
SurnameTextBox.Text = DisplayCustomersListBox.Text.Substring(5, 7)
ForenameTextBox.Text = DisplayCustomersListBox.Text.Substring(12, 10)

Name|Age|Department|Salary
All I want is when I select the department in the drop down, the list should show all the names under the department. Also, when I select the name in the list and click delete. It should delete the complete record from the Table.

View 2 RepliesI have an ini File which I use as an "index" of jar files. The Jars are declared in it like:
Name of the jar=c:Path
So when my application starts, the ini file gets loaded in a list view. I have a delete button, with which I want to delete the jars from the list view and the ini file. It must be possible to delete multi choiced jar references. so I thought to do it with for each, so that every selected item get searched in the ini and deleted. The Error is, that the String (is correct, I tested it with a messagebox) get analysed - Unknown escape sequence R (The error is between the ** **)
My Code:
Private Sub jarDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles jarDelete.Click

ListView1.Items.Remove(item)

I have a server that exports a file to our server every wed and sat. The file is a .csv file, so I created a batch file to move that to a folder and rename it to .xls. My problem is that there are things on that excel file that that the dealership doesn't want, like a cost column and some other blank ones i need to delete. So I want to write a program that will read that file into the program, delete the columns, and then write it back to file. So when they go into the excel file those columns won't be there. So i have to do this to 3 different ones because there are 3 different dealerships. So far this is what I have. I would like to create this on a Console App, because I want to be able to just run this from the dos prompt, or I think I'm just going to have a schedule run it for me at a specific time on wed and sat. But this was created in the Forms App

I've made a dataset using the dataset designer, and I'm trying to add a column to reflect changes made to the database (added a column, nothing fancy). Is there a way to 'refresh' the dataset schema from the datasource without deleting my adapter (and all the methods and queries I've created)?

View 4 RepliesI have a DataGridView containing a large number of columns. I want the users to be able to select multiple columns and then select a menu item to hide the selected columns. For example a user might selected columns 5 through 10 and I want the program to hide those columns. I know how to hide columns, one at a time. I can get the count of selected columns but I have not figured out how to get the index to the left-most selected column. Trial and error is such a slow process.
Considering the huge number of options offered by the DataGridView tool, it would be nice if this forum had a special category for the DataGridView (common to VB and C#).
Finally I got the desired results but it took a lot of coding, looping through the selected cells to find the one with the lowest column index, then a second loop to count previously-hidden columns, then a third loop for hiding the selected columns, stepping past previously-hidden columns and declining to hide frozen columns.

It's working fine but at the moment any column in the datagridview can be selected and transferred which causes an error.
So I want to create an If Then statement which confirms that the selected column with the dgv is the PK_ID (customer ID) column before processing the rest of the code. I've tried playing around with "If dgvCustomerSearch.SelectedColumns("PK_ID") Then" but a "Value of type...cannot be converted to Integer" error occurs.
