What would be the best way to run a subroutine over and over again every X seconds. I want to avoid creating an infinite while loop to do this because this sub needs to be called repeatedly while the rest of the program is still active and responding.

View 7 RepliesI am using Visual Basic 2008 for a Windows Form application. I have a PictureBox on the form that I need to display a series of 12 JPG files, one every four seconds. For the life of me, I cannot seem to figure out how to get the Timer control and its Click event to work.
In pseudo code, I need something as simple as the following:
1. show JPG #1 in picture box
2. 4 second delay
3. show JPG #2 in picture box
4. 4 second delay
etc.
I have a Timer on the Form set with Interval = 4000. I have a PictureBox. I have all the images in the Project. I am embarrassed to say that I have spent 4-5 hours searching the Web for sample code or something helpful, but am still stuck.
All the elements are there. It's just a matter of understanding how to pause the image displayed in the picturebox for 4 seconds before moving onto the next image in the series.

Is there an option to set a time interval between each check?

I have a quesion about using the timer1 function. I am a complete virgin when it comes to programming, so please be kind. I have a project that is using an NCD relay controller to control linear actuators. I want one relay to turn on and then stay on for 10 seconds and then turn off. I set the timer1 properties to enable with an interval time of 10000. I am programming a button to turn on the relay then wait 10 seconds then turn the relay off. All that happens is the relay comes on then off immediatley. I have tryed to do this several different ways with the same results. It is though the timer1 is not getting recognized. So my main question is, what steps am I missing, and how do I get a delay of 10 seconds before the program recognizes the turnoffrelay command?

View 2 RepliesBackground Story: My program contains a form and 3 buttons (Add New, Delete, Edit...etc), and it works perfectly. Recently, I decided to add menuStrip, since it helps end-user to work faster. So, I put the menu strip coding.
However.....Sometimes, it works normally. But sometimes it works very strange.
Strange 1. When I chose the "Add New" item in the menu, the Add New Form will be showing up, and then I clicked on the Cancel button in the Add New Form. The Form kept showing up repeatedly. But sometimes, it works normally. (Note: Add New Form's Cancel button contains one line simply coding, it's "me.close")
Strange 2. When I chose "Delete" item in the menu, the MsgBox showing up (since I coded it and it's a warning message to end-users), but the MenuStrip KEPT showing up, so the MenuStrip overlapping the MsgBox. (I expected the MenuStrip disappear in this situation)
Is some codings I have done incorrectly?

I have this datetimepicker in my application. The user can select the time they want. I used a custom one and this is the code I used:
Code:
TimeFrom_dtp.CustomFormat = "HH:mm"
TimeTo_dtp.CustomFormat = "HH:mm"
I also have an array; a combobox and a variable called: TimeInterval. here is the code I use:
Code:
Dim ReadingFrequency(7) As Double
Dim TimeInterval As Integer
Private Sub CustomizeGraph_frm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[code]....
What I want is to change how much the datetimepicker increments, when you click the arrows, depending on the value that is entered in the combobox. For example, if the user has 2 hours in the combobox, the datetimepicker will increment by two hours and won't let the user change the minutes. If the user selects 15 minutes, the minutes will increment by 15 on the datetimepicker.

So, I have two timers. 1 Timer is set with an interval of 1000 (milliseconds), therefore it goes off every 1 second. For some reason, when I set the interval on the same timer to 1, it goes off 100 times every second. Shouldn't it go off 1000 times every second? What's going on?
