I am trying to use a timer and stopwatches to control timed events and it's not working. This should be easy to implement and I don't understand why it's not working.
Code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
'hide label1 after 3 seconds.

The word in the textbox will display for a random time 1min to 7 min, then the textbox displays another word randomly selected from the word list.
View 1 RepliesI created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically.

View 12 RepliesI have a timer in vb.net and it's interval is 1000ms ,. i have placed in it's timer_tick event a code that will print screen the screen and save it to a database.The problem is when i click outside of the form, or loosing the focus of the mouse to the form containing that timer/printscreen, the timer stops.

do wpf forms have a timer control?
View 1 RepliesI have a timer that I've established that I have set to run at a 20ms interval.Within that timer code, I have some code that is performing a visual display, moving a graphic incrementally.This all works great on a nice fast machine, when I can be sure that the "work" is actually being completed before it's "called" again by the timer.It does not behave well on a slower machine, when I suspect that the timer is being called again before the work is being done from the previous call(s).
I've tried establishing a global boolean variable called "Timer1Active". I set this variable when I enter the code to TRUE, and to FALSE as I exit the procedure. I also check, using an IF statement if it is true at the beginning of the procedure, skipping all of the procedure if it's not yet been set back to false.This approach seems to stop the visual portion from happening altogether. I think, anyway. That or it's now way faster and I can't see it at all (but I doubt it).

View 1 RepliesI have never dealt with dynamic control events before. I have a variable number of a controls each created at runtime. However I don't know how to code events for each control as they should do different things.

View 4 RepliesI just opened up an Asp.NET project solution for some maintenance. I usually use C# but this project is in VB. When clicking on a form's button and looking at the properties view, I see no way to view the events for that button. Usually the lightning bolt button would be present in the properties view and clicking it would show all events for the control. From there you could see the event handlers or create an event handler by double clicking. Why don't I see that in this project. Is it an IDE setting or a VB project thing?
P.S. I thought I was in VS 2005 but it's 2003. 2003 usually shows me the lightning bolt though in my c# projects.

View 4 RepliesI'm using VS2008, vb.net, and winforms. I've got 3 comboboxes on the same form who are all bound to the same data. If an item is added in one, I want the change reflected in the other two. I'm trying to create one sub to handle the adding of an item for all three combos. I found that the "sender" object appears to contain the control name. The Sub I created is not working quite right because after the item is added, the combo list display repeats itself. So instead of "Item1, Item2, Item3" after adding "Item3", I get "Item1", "Item2", "Item1", "Item2", "Item3". This coding works fine if I were to copy it to the Key_Down event for each combo and reference it directly (for example, use cboSpecialty1.Items.[code]...
View 4 RepliesI'd like to temporarily disable events for a given control. For example, the SelectionChanged event on a combobox might be used to update a display every time the user changes the combobox... but while I'm filling the combobox with values, I don't want the SelectionChanged event to be firing over and over... I need to disable events while the combobox is being populated. How do I do this?
