VS 2008 - IDE Bug - Make Certain Forms Automatically Close After A Timeout Period
Sep 14, 2010
I caused the VB.NET2008 IDE to do something extremely odd and unintentional with some code I was writing. As some of you know, I mostly write programs for industrial equipment. On one of our products, I needed to make certain forms automatically close after a timeout period. To do this, I began programming a usercontrol with a Timer on it (interval = 1000) and a ProgressBar. Timer.Enabled was set to the Enabled event so I could toggle it. When the control counted to it's timeout period, it would call Me.ParentForm.Close
So I build my project, and drop it on a form in the IDE and I see it begins counting! Huh... I had no idea timers were active in the IDE. I wonder what happens when it hit's it's trigger? I figure probably nothing since Me.ParentForm was actually the designer. When it triggered, the whole IDE crashes without save. I tried it twice now. Here's my

Out of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)

How Do I Make Button.click Event Perform both the enter and period(del) keys on the numeric keypad? [Code] Case Keys.Enter and Case Keys.Separator do not work. Nor does anything like Keys.OEMPeriod for the period(del) key. I've also tried calling the enter key in a KeyPress event etc. But to no avail. Any ideas? I'm trying to mimic Windows calc.exe for a school project and thought I'd try throwing in a few extras such as numeric keypad functionality.

I currently have a working program that creates one colored pixel in a Bitmap, displays the bitmap in a pictureBox, and "jiggles" the pixel by making it move in a random direction by 1 pixel every time a button is clicked. I want to make the pixel move automatically until a Stop button is pressed.

The problem: A dialog's FormClosing() event is raised if it's a child, ie it's Owner property is set to the parent form, but NOT if it's a child-of-a-child. So closing the main form does not call the closing event on any grandchildren dialogs.
The Details: A dialog prompts to "Save Changes?", with YesNoCancel buttons, in the FormClosing() event. Clicking Cancel keeps the dialog open, ie cancel closing.
Private Sub Dialog_FormClosing(...) Handles Me.FormClosing
If MessageBox.Show("Save Changes?", YesNoCancel) = No Then
e.Cancel = True
[Code].....
Then the FormClosing() event on the child does not raise, if the top-most parent is closed.
Is this a know design limitation in the framework? Is there anything I should consider before I start hacking a nasty solution for this?

i have a problem with trying to get 2 forms to close at different times using a timer on each of the 2 forms.
This is my form layout:
Quote:
frmMain
Frm1
Frm2
Frm1 and Frm2 are identical to each other. FrmMain has 2 buttons on it. One button to call Frm1 and the other to call Frm2.Frm1 and Frm2 each has a timer. It counts down to 0 and then does a .close(). However, if i pause between clicking the second button they both seem to always disappears at the same time.I would do something like this...
Click on the first button (showing the Frm1 form)
wait about 10 secs...Click on the second button (showing the Frm2 form)they both are shown on screen...hen they both disappear at the same time.... which shouldn't happen since i clicked the Frm2 box 10 seconds AFTER Frm1... So Frm1 should hide before Frm2 does...but it does not.

In VB.NET when I am closing a form and no longer need to use it, do I do a me.Close() and me.Dispose()? Does the dispose erase the form from memory?

Is there any way I could have the Minimize button on form while at the same time to have the Close button [X] deactivated (or removed or anything) ? I just want to give the opportunity to the user to minimize the form , but to force him to close the form with the Close mutton , not with the X button

In a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another

I have looked through couple of threads about making the trial application to be expired within certain time. Most of the advice is to set a timer and store it in somewhere in the system with encrytion. Then later decrypt and compare with the date installed in the system.

Dows anyone know how I can build a timeout feature into a windows forms app.
The app is event driven, but I am thinking of somehow using a timer which counts down for say 10minutes, and one the timer ticks then we time out the user.
The problem I have is how can I reset the timer each time the mouse is moved or clicked.

I wanted to open a URL from my VB.net Application on a button click event (for sending SMS from my application). However, I don't want my users to know about it & I don't want to have a browser pop up and execute the URL.
Is it possible to do it invisibly? And once it is done, is it possible to close the invisible browser window too?

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.

I have created an application that uses two forms one is displayed on a touchscreen and is a basic input form, the other is displayed on a large display monitor and is basically an information form, both displays are connected to the same pc. The program works great I have just one annoyance is if the program is restarted it displays both forms on the touchscreen and I have to drag the information form onto the big display. Is there a way to specify on load that each form gets displayed maximized on a certain screen so I don't have to drag one form onto the correct screen?
