Public Sub GenereTextBox(ByVal rep As String)
Dim txt As New TextBox
Dim fnt As Font
fnt = Me.Font
txt.Location = New Drawing.Point(26 + NbreCacher * (68), txtOrdonnee)
[Code] .....
And I want delete some buttons create when I click on my button, but I don't how I can do, because these buttons are create in code??
I have never programmed anything in my life -- and I'm learning VB from a tutorial which I found here:[URL]...So I've created my button and added the code. Then it says:
"Now run your first application!"I have no idea how to do that!
I created a listbox and button in my application using vb code.When the user select an item in the listbox and click on the remove button, the item will be removed from the listbox. I know how to remove the item in the listbox, but I don't know what coding to add to activate the click event on the button.
View 4 RepliesI have this code to create a new button
Dim NewButton As New Button

This works. But I want to change what happens upon clicking NewButton. It should start an application. I tried NewButton.Click but that event doesn't exist.
I'm trying to code the delete button in my binding navigator and I keep running into errors. This is what I have:Dim msg As String = "Are you sure you want to delete the current record? " If MessageBox.Show(msg, "Confirm Delete", _ MessageBoxButtons.YesNo) = DialogResult.Yes Then _CustomersBindingSource.Remove(DataGridView1.CurrentRow)
End If
Me.TableAdapterManager.UpdateAll(Me.DatabaseDataSet1)
Even when I change it to _CustomersBindingSource.CancelEdit and I debug it, the Delete button in the binding navigator looks like it set to enabled = false, but in the properites it's set to true.Even if I add enabled = true at the top
I have a binding navigator in my project and it works just fine.My question is where, if at all, can I find the code that is run when the delete button on the navigator is pressed.My reason for wanting to know this is I want to be able to give the user a second chance when the delete button is pressed.I want to ask the user if they are sure that they want to delete the record by using a msgbox.If the user says yes I will delete if they say no then I do not want the record deleted.I tried putting logic in the BindingNavigator DeleteItem_Click but was not successful.

I've tried for loop over the controls in panel1 to dispose of any still on there in both the page_load and page_init subs, but neither had an effect. I don't know if it might have something to do with controls having the same IDs after the postback.
ive got code like the code below that creates textboxes dynamically. I want to be able to click a button and delete all of these textboxes i make, however im not sure how to do this. When i tell the program to remove the TBIndex control it does not do anything. The only way i get it to work is if i put the command in the same sub as this code. This code runs in a loop by the way.
So if the loop runs one time and creates the TBIndex control and i have a line of code right after to remove the textbox, then it does not show up on my form. But if i put the command in to remove the textboxes somewhere else and run the code the loop runs abunch of times and creates all teh textboxes and the loop is complete, then the remove control part is called and nothing happens. I just need a way to clear all the textboxes off my form with like a button. I also tried painting over the textboxes with a big grey rectangle but that dindt work.
TBIndex.Width = 54
TBIndex.Height = 20
TBIndex.Visible = True

In my project, I have a local dataset (XSD) that I am using as local-temporary tables. I am getting a System.InvalidCastException when trying to access the field in one the tables. I believe this is because I my code is (incorrectly) not setting a field's value in a row before trying to access it.My problem is that the exception is breaking in the designer file and not in my code. As a result, I'm having difficulting determining which line of my code reading the field value before it has been set. Is there any way to configure Visual Studio to break in my code instead of in the designer created file?

I have created 3 arrays of buttons for a form which manipulates the value in a combo box or 2 by the name of the button ( buttons named 2 through to about 70 )
This works great but the problem is, now that the buttons are in, I want to be able to change the color of the buttons when another button is clicked
ie. The first bunch of buttons is a list of locations all with unique text.the second bunch of buttons is events that happen, sign on, sign off, beach open and beach closed.
What i want to be able to do is change the color of the button clicked "before" i click sign on, sign off, beach open or beach closed.
I do not know how to reference these buttons in my code as for starters, they are numbers, which is a big no no apparently. Also, even if i change the name from just a number to something like cmdBeach(i) when creating them, i still can't refer back to cmdBeach5 in my code as the button doesn't exist yet

I created a form with 2 labels 2 textboxes and a button. Basically it is a login from. When I launch the form it shows the blinking cursor in the 1st textbox(this is ok) but when i try to type nothing happens. Once i click the form(not the textbox-textbox works too but wanted to note it was the form) it works. I have tried doing textbox1.focus(). I have tried doing the form.focus(). Neither were successful. It may have nothing to do with focus but it seems to be that to me.

View 2 RepliesI created a button in DatarGrid. Now I want to click that button and only when I click the button should the event be fired. Actually I want to Delete that particular row once the button is clicked. However, when I click the button, the Event: CellContentClick of the DataGrid gets fired. And that means if you click anywhere on the Datagrid, that even will be fired, and that makes no sense to put a Delete button. So I want to keep the Delete button and once the Delete button event gets fired, the record gets deleted.
