I am creating a Windows Foms Application. When a form is shown, the focus is inside a causesValidation textbox. If the user presses the Escape key, the app insists on completing the validation of the empty textbox.
[Code]....
In my form there is a "Validating" event on a textbox.
This form also has a "Cancel" button.
Is there a way to not execute the "Validating" event when the user clicks on the "Cancel" button?
I am having a problem with the cellvalidating event constantly firing when the datagrid is refreshed (since the trigger that fires the event is the originally selected cell losing focus).I would like to remove the event handler for this at certain points of my code so that it does not fire but the examples I have come across on MSDN don't appear to do anything, so I guess I must be doing something wrong.[code]
View 1 RepliesUsing 2 forms how would I click one button, from another form? ie In VB 4,5,6, I would used to do it as:-
Form 1:
private sub Command1_Click()
msgbox "Say Hello"
End Sub[code].....
If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?
I have numerous buttons on a form, one each to select a playing card (52 buttons). When the Card(button) is selected I want to highlight it by changing the border from black to Red, then if reclicked from change back from red to black, easy enough (if then else). So that I do not have to copy this code 52 times I wanted to create a module as follows:
Sub ChangeButtonBorderColor(ByRef ButtonName)
If (Equals(ButtonName.BorderBrush, Brushes.Red)) Then
ButtonName.BorderBrush = Brushes.Black

How to make a link button visible after another button has been clicked in asp.net(vb) in button_click()
it says error as "Object reference not set to an instance of an object."

Dim receipt As LinkButton = FormView1.FindControl("LinkButton1")
' receipt.Enabled = "true"

I have already done the creation of button and the dragging of button at runtime already.But now i need to know how do i save the last dragged button on the form and also detect the name of the last clicked button.so lets say i now drag a button to coordinates 25,254. so when i exit the form and the next time i launch it, the button will still be at 25,254. and this one will go on for the number of button i created like 100. so when i launch the form the 100 button will be at the exact position where i last saved them.the second part is lets say i created button1 and button2 on the form in runtime. so when i clicked the first button, it should display button1. and if i clicked on button 2, it should say button2. same goes for like 100buttons.

I have a validating event for a txtbox called txtname. If the user tries to leave txtname for another txt box without entering their name a messagebox comes up giving an error. I have an exit button which will when clicked ask you if you really want to leave then you can choose yes or no. I can't seem to figure out how to allow the user to click the exit button while leaving the txtname blank so it would bypass the error message and only bring up the exit prompt. Here's what I have coded for the validating event and the exit event.
Private Sub txtName_Validating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles txtName.Validating
If IsNumeric(txtName.Text) Then

i have a form with 10 designated slots for letter to be entered (Like the free letter spaces on hangman), above these are 10 adjacent labels with a full stop "." as the text value, now i have created a button, Q to detect whether there is a. in the first box, and if there is enter the letter Q (Letter1.text = "Q"), elseif check the same for the second box. Now my problem is when i click the button, it still does nothing and letter 1 remains "." instead of "Q". also how would i end this string of else ifs? as in what if every text box is full then do what?

View 1 RepliesI have a group of RadioButtons in VB.NET. I would like to create one function that will handle all of them together. My code is below.
[Code]...
When you click on a button control on a web form visual studio automatically put in this code for you in the code behind.
Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnFlightInfo.Click
end Sub
Say for example, I wanted to call this method from another method. How would I do that? I know that the sender is the actual button object, but what is e? Here is what I have so far inside another sub. Just trying to get a better understanding of how this method works.
btnSave_Click(btnSave, ??what would you put there??)
I've 100 buttons created dynamically in a form. how can i add event handler to them?
View 3 RepliesReading about VB .NET I found out that now it is possible to handle more than one control with the same event handler. What I want is to specify what my Radio buttons will have to do, using a single sub instead of using a sub for each of them. However I am still far from achieving that. I am using something like that:
Private Sub ForAllRadioButtons_CheckedChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged, RadioButton2.CheckedChanged, RadioButton3.CheckedChanged
If sender.name = RadioButton1 Then
Code 1 ...
ElseIf sender.name = RadioButton2 Then
Code 2 ...
ElseIf sender.name = RadioButton3 Then
Code 3 ...
End If
End Sub
However, I get an error message which says :
Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.RadioButton'.
I bet 100 $ that it's something that I don't do it right . Unfortunately I can't get that money. Would it be the same if use the Click event instead of the CheckedChanged ?
During the process of my program I am creating several different buttons depending on what file the user selects. I have been able to create these buttons and I would like to set up the event handler so when the user selects one of these buttons it pops up a message box that shows the user the name of the button they just clicked on. The message box isn't the goal of what I would like to do with it but If I could get that to work I would be able to alter the code to get it to work the way I want it to.
Below is my code that I currently have. I don't have the event handler doing anything at this time as I can't seem to get it to work I am still playing around with it.
ublic Sub resizebuttons()
Dim X As Integer = 175
For Each item As String In CSVInput.selected

I have partially coded a project seen below:
Public Class frmBroadwaytickets
'Defining the cost per ticket
Const _cdecticketprice As Decimal = 153.5D
[Code]....
My btndisplay cost works, but my btnexitprogram does not close the application when clicked. I've ensured the button is correctly named and enabled. But when I click it does not close out, I use this simple code in other programs and it works.
I have a calculate button that, if clicked more than once adds the total of what I previously had to the new total as I am using a loop. I was thinking that I could get around this by only allowing the button to be clicked once, and if the user attempts to do this more than once a messagebox will appear saying that you can only calculate the price once and the form resets but i can't seem to get any code working.
