Can't Prevent A Form Shown With ShowDialog From Closing When User Clicks OK Button
Jul 18, 2011
I have a VB.NET 2010 Forms Application which includes a form with a textbox, and two buttons which I call from the main form using .ShowDialog
I've messed with something such that I can no longer prevent the dialog from closing when the user clicks the Ok button but has entered invalid information.
Here is the handler for the OK button's click event:
Private Sub cmdOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdOK.Click
If SomethingIsWrongWithWhatTheUserEntered Then
On each of my form I have put an 'Exit' button. When user clicks it, another form is displayed (I don't want to use 'MessageBox') asking user whether he really wants to quit. If user clicks yes the form closes. If user clicks no, form is redisplayed.
However, out of 4 forms only one form refuses to redisplay. The code is exactly same on all forms. I have included 2 Express 2008 projects showing one form each in the zip file apps-ssk.zip
i am building vb.net web application with vs2010 i have in the form two buttons, accept and reject What i want is when i click on accept or reject, it stays disable for clicking until the code on his click event is fully executed now when i run the application, i can click several times on the button before the code on the click event is executed?
I am creating a VB program that has a Main class, and 4 windows forms. Each of the forms has a back and a next button to navigate trough the forms. The problem is that when I hit next (Here is the code)
Private Sub continueButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles continueButton.Click
To prevent multiple clicks on button in VB6 I have add button.enabled=false in start procedure and button.enabled=true in end. But in Vb.Net all clicks are stored in memory and wher procedure is over - then it started again. You can see it in this example:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Button1.Enabled = False
Would it be possible to add a .exe to my resources and when the user clicks a button on the form it will create a directory ( C:My apps ).then add the .exe from my resources and launch the .exe from that folder.
I add a button to a form each time the user clicks a menu option as:
[Code]....
This draws a small blue line at the bottom of the button to show it is highlighted. Just like the mouseoverbackcolor property on a button except this will draw the line. It works fine until you slide the mouse very fast between the buttons. It is as if the mouseleave event doesnt always fire.
I am writing an application that needs to be running all the time and I don't want the user to be able to close it. I don't want to hide the process from Task Manager. All I need is that when the user tries to terminate the process, he has to enter a password.
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?
Lets say i label "label1" , and 2 buttons named "button1" and "btnRefresh " [code]So , when user press the button 1 , the text will change. But what should i put inside btnRefresh to reload the forms ? and display the default label.text = "Form Load" ???
I am working on a Text editor. The problem I have come to, is that when a user clicks a button, I want all the text to be displayed on one line. The reason for this is I am having problems being able to upload CSV email files on a website I am working on, because the format isn't like email, email, email, email. Instead it is like
email, email, email,
So I have written a program that will format it. Only It still isn't working. I need it to recognise when there is a ".com," or something.
I'm running a survey to count how many times a user clicks the left mouse button. But the mouse click applies outside of the form, even applies to clicking start or other locations of the of the PC when the form has been minimized with a NotifyIcon. I know how to count the mouse clicks within a form but not outside the form. Somehow I feel I need to use a timer event but need it to apply outside the form. The timer tick event doesn't have a e.button event or mouse down event or mouse click for that matter. Whats a good way to get this function to apply outside the form?
In my form I have a text box (txtJobNo) , a Find button and a dtagridview to display the record for a unique JobNumber. Everything works fine to retrieve data, my problem is the display part in the datagrid view, it replaced the first record. I want to keep all records in place until I am done and then insert all those records in a new table. Please HELP. Please find my code below:

Here's the problem I have. I want a message box to pop up if no dice are selected and the user clicks the roll button. So far the only way I have been able to accomplish this is to put the same code under each radio button:
I want to have this code only once. But If I put it outside of the If/Then bracket and no dice are selected, the msgbox pops up but also the buttons that I want to remain hidden until dice are chosen pop up. How do I get the msg box to pop up and stop...don't execute any more code.
Heres' the code so far. trying to keep it relatively simple:
Code: Private Sub RollButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RollButton.Click 'see which radio button is checked and display random number accordingly If TwentySidedRadioButton.Checked Then RolledValueTextBox.Text = GenerateRandom.Next(1, 20)

I have a problem with a Save button on a toolbar firing the click event twice if the user double clicks the button as opposed to single clicking.Disabling the double click on the toolbar itself seems to make no difference as it is the actual save button that is being clicked twice.I have tried setting a Boolean to stop the event firing twice but it is just too quick!I didn't have this problem with my code before as the server call was not async... and reverting back is not really an option.
My code is as follows:
Protected Sub tlbOrdQuot_ButonClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ToolBarButtonClickEventArgs) Handles tlbOrdQuot.ButtonClick

In my application, the user clicks a single button and the program displays each network adapter description into a message box and then gets all the ip info for the workstation and places it into a text file and opens that text for reading. What I would really like for it to do would be to display all the network adapters into a single messagebox instead of messagebox for every adapter like it is currently doing. Here is the code I have on that button. Let me know if anyone needs more info or has any questions:
I'm trying to make an application where when the user clicks a button, it generates a series of 100 random numbers between 1 and 1000, and then saves those numbers in a text file.
