Forms :: Skip Validation Of Active Control When Form's Close Button Is Clicked
Aug 12, 2009
Is there any way to skip a the validating event of the active control when the close button of the form is clicked. It is very annoying when user wants to close the form, but due to the validate event of the active control, it asks for the valid input. The user is forced to give valid input to close the form. I have searched a lot for this on net but no any proper solution could be found.
I'm making an equation program and I want to have a main menu where the user can select an equation and then when one of the buttons is clicked, it closes the "selection" form and opens the appropriate form. For now I just have it set to show the proper form (for example, Form3.Show) but when I try to do something like Me.Close() after it, everything closes instead of keeping Form3 open.
One of the VBF member was asking how to add a close button on the BindingNavigator control once and reuse it on all other forms, so I try to create a custom bindingnavigator class that inherits the BindingNavigator class.Below is the inherited class:
[Code]...
The thing that I can't figure out is that it looks OK in design mode, but at run time, the custom binding navigator shows 2 "Close" buttons. Only one of them will close the form when clicked, the other one doesn't function. See the attached image.
I am developing an application in Vb.net 2008.In it I wish to add a conformation message box when ever someone attempts to close the application window.So I want to detect that some one has clicked on close button which is present on title-bar of my window.
I have a backup script i made in VB. part of the code im having trouble with:
HTML
code:
Now this code is executed when a button is clicked, if the folder does exists, it displays a message and continues the backup. however if it does not it displays displays "does not exist box" then i want the application to close.
I played around with the application.exit commands but it seems like the code just skips over it, and continues to try and backup the data, then errors out. how do i make the application close, if the dir does not exist?
A wrong entry into a textbox causes the errorprovider to appear (set in the validation event e.cancel=true).Can I close the form (X in the upper right corner)?
I just starting to use MDI form. I can show the child MDI form, without any problem. My problem is that I want to close the child form also from the parent menu bar. This is my code:
Private Sub CloseToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CloseToolStripMenuItem.Click Dim frmActive As Form = Me.ActivateMdiChild
Private Sub txtAIT_Validating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles txtAIT.Validating If txtAIT.Text <> "" Then
[Code]....
In form I have a close/Cancel button, and I set Causes Validation = false, and on its Click I used "Me.Close", but form can not be closed.
Button Works fine, but form can not be closed until text field has been validated.
Is there an way to supress the validating event of textbox when the forms close button(X) is pressed. In the textbox validating event , if the condition fails then i am displaying an messagebox. Now suppose if the textbox has the focus and user directly presses the forms X button , then the messagebox is displayed
I want to get the active control (control which has the focus or where the cursor is on) each time the cursor moves to another control or each time a control receives a focus.
I have set up a notify icon for my form. I want to make it so that when the user clicks the close button that it doesn't close the form it just takes it to shows the notify icon. They can exit the program from the notify icon. Can someone tell me how to keep it running?
Is it possible to skip a code block when a synclock is active?
For instance:
A object of class Bicycle is used by thread 1 and has a synclock on it.
Then thread 2 comes along and needs to know if the lights of the bike are working. But if there is a synclock active then thread 2 just forgets about checking the lights and goes to make a delicious chocolate pie.
I'm working on a project that will create new windows components. (If this is possible). I have made a button that creates new forms when clicked in the MDI container.Now I'm just wondering if someone can figure out a code to make it so when I click a button it creates a new button on the new created form. [code]
using System; using System.Collections.Generic; using System.ComponentModel;
[Code].....
So what I am trying to do is to get textBox1 to show which button i have clicked. Because I have Form_Activated I only see changes when i reactivate the Form. So I would like to have Event that is Active all the time and listens to everything that happens in Application and NOT only when something is clicked or some text have changed.
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 situation where me.close() doesn't close the form. I have a form with a button with the code seen below. What happens when the button is clicked is the new form shows, but the original form(calling form) is still there. When I go into debug mode, I can see the me.close() execute, but nothing happens (calling form stays open). When I close the second form both forms close. If I comment out the call for the second form to open the first form closes without problem.
Private Sub cmdNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdNext.Click Dim f As New frmOrder3
I'm using VB.net '08 express and I have a form in a program with a picturebox. I have a series of images in My.Resources. What I am trying to do is get the images in the box to change in sequence whenever the button is clicked.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim sequence As Integer Select Case sequence Case 1
[code]....
When the button is clicked, the 1st image appears and the button then does nothing.
I have a form with many buttons on it and I would like to loop through all the controls in a group control and find out which button is clicked.
I plan to use the click event of the button and I know it's easy to create a click event procedure for all of the buttons but would like to avoid that.
I'm having a strange problem with the OnClick event. In an ArcGIS application using VB.Net, I have a button set up with the following
AddItem("CommandAnalyseResults") The following module segment contains the OnClick event: Public NotInheritable Class CommandAnalyseResults Inherits BaseTool <more code...> Public Overrides Sub OnClick()
[Code]...
The OnClick event gets triggered no problem the first time I click on the button. However if I then close the window the button code creates and then click on the button again, the OnClick code is not triggered.
If I click on a different button then click back on the 'problem' button a 2nd time, it does seem to trigger the code!
How do you hide a user control when a button is clicked? I know how to hide a form but not a control. If it is possible to actually remove the usercontrol from the panel that would be awesome to and then have it show again once I click the other Icon. [cod]e...
WHen we click on site whether left click or right....Control goes to IEDoc_MouseDown event,I just want to ask is that possible to know taht which element is clicked..Suppose we right click on link,is that possible to know it that link is clicked.
Public Class Form2 Dim WithEvents IEDoc As System.Windows.Forms.HtmlDocument Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs)
when i clicked the final button to display my results "as string" it still showeed the number?? here is the code i wrote, is relativley simple, but the theory doesnt make scence to me Basicly its a box with 3 lables, (first name, surname and age), 3 text boxes (for the user to input this info) and a button at the bottom called "display in message box" so when i click the button, it displays the users input in the form as a message box. [code] what i dont get is if i said to VB that vaiable "Complete" was STRING then howcome it still displays the AGE which is an Integer (a number) not a string??
