VS 2008 : Get 2 Forms To Close At Different Times Using A Timer On Each Of The 2 Forms?
Apr 21, 2010
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.

Imagine that I have a System.Windows.Forms.Timer with 1000 ms interval. If I call Timer.Start() method and after 500 ms I call again Timer.Start() what happens? The second Start call will reset the interval or not? Are there any side effects?

I have two forms frmMain and frmNew, and one module modMain. In modMain I hold public variables which are needed for application. My question is how to open and close those two forms when needed? I ask this because if i set frmMain as startup form, then when closed, application will end, and one of those two forms will always be displayed. Also if I set frmNew as startup form, then when I close this form, application will also end. Is there a way to do this from module or something so my application won't end after closing and opening any of those two forms?

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

I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

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

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 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

Create a simple Times Table program which will allow the user to enter an integer value n (between 1 and 20) into a textbox. On the click of a button output to a label the n times tables. Use a For�Next loop to perform the repetition.

I would like to know how to make a button click only so many times until it becomes disabled.
I would also like to know how to keep what is put in a RichTextBox there, without erasing the other text;
Example: Two buttons, the first puts "1" into the RTB, and the second puts "2" into the RTB. However when I press the second button, it over writes the first value.
How can I prevent this?
You Can Ignore this question below;
Old Question: I am working on a counter, and want to know how to make a button show itself if I hid it.
I have:
CODE:
And would like to know how to make one of the buttons visible again, with one big button.
I know it has something to do with an "If" statement.
Answer: Button#.Show()

I'm developing a windows application. I have a form in which there is a list box and a treeview control. My purpose is to fill treeview according to list item clicks. This is done using a pair of subroutines called ReloadPermissions and FillMenuItem:
Private Sub ReloadPermissions()
Dim p As New Permissions
Dim i As Integer
Dim it As TreeNode
Dim el As New List(Of String)
[Code]...
There are only two subroutines in which nodes are added to treeview control, and they are subroutines above. The problem is that whenever list item is clicked, node count displayed in treeview is increased!!! I checked number of nodes before and after call to tvPermissions.Nodes.Clear() using MsgBox. Results show that number of nodes isn't increased (1 before call, 0 after call, again 1 after ReloadPermissions() is called), but what is displayed doesn't show such a behavior! Refreshing window by putting it under other windows or call to tvPermissions.Refresh() has no effect.

i'm utilising a couple of controls to kick off a process within my form - in short i have a DateTimePicker, Timer, CheckBox. The user enters the time they wish the process to run in the DateTimePicker (which has its format set to Time), ticks the CheckBox, which kicks off the Timer with an interval of 900ms. The Timer_Tick event checks if the DateTimePicker.Value is now and if so, does something. My problem is that either the DateTimePicker.Value never equals now or that the Timer_Tick event is never actually called.
I welcome any input into better ways of accomplishing this, i am conscious that polling for the time every second is a drain of resources but the only alternative i can see is a service which is overkill
