Calling A Program In A Timer In Vb?
Jul 8, 2011
I am facing a lil bit of problem and my problem is I am calling a function in a timer device, and that function reads the data from the data base what it actually does is, first the timer capture hotkeys pressed from the keyboard and then calls a function Readit() and in Readit() it actually compares if the key has some data associated with it if it has some data it reads that data into a a variable buff and sends it to the active window whichever window is active.Main problem is my function won't stop reading and sending the same data to the active window,

I'm developing this procedure using a timer object. The thing is the procedure is not in the timer's event procedure but I want it to depend on the timer's interval when executing, it's just not calling the timer procedure. How can u declare objects and use their event procedures in code.

I have successfully set up a timer in visual basic, see the code below. My timer uses case statements and at specific case/time it calls a function, 'ShuttleA'. 'ShuttleA' function, is a function that 'getskeystate', which inturn from the user interface tallies a response in a text box. My problem is that the program runs fine when calling the function at eg; at 10 seconds, case 10. But I want to be able to call the function e.g., at 8 seconds to 11 seconds. Or create a tolerance of e.g., 1 second either side of e.g., 10.
PrivateSub Timer1_Tick(ByVal sender As System.Object,ByVal eAs System.EventArgs)Handles Timer1.Tick
Dim secondsAsInteger
seconds += 1
Label1.Text = seconds
SelectCase seconds

I have a .dll file (Interop.ACTMULTILib.dll) that I use to connect to a PLC. This .dll contains a sub called ReadDeviceBlock2(byval devicename as string, byval size as integer, byref data as short). When I call this method in my main it works fine, if I call it from another method that was called by main it works as well.However, it doesn't work when I call it from my Timer_Elapsed sub? I guess this has to do something with threads but I can't figure it out.
Module Main
Private Timer As New System.Timers.Timer
Private PLC As New ACTMULTILib.ActEasyIF
Private DataSet As new DataSet[code].....

i just wanted to calafiy i know how to call a different sub and everything but i wanted to know if you could call a different program all together.
say you have on the first WITCH POWER DO YOU CHOSE. then they hit NEXT and it takes them to a whole new layout and program like saved in a different folder.
i think you do this like you would with webpages
Call ../folder/folder/frmbladeda
if thats wrong or there is an eazyer way also would i do the same thing with varibles like how you do Call addtogether(strone, strtwo) addtogether would be the private sub and strone and strtwo would the the varibles in that said sub.
make sure i want to call a different program like 3 folders away

I have written a VB Program for calculating Power requirements for Heating Water, Air etc. There are some standard formulae, which require inputs in fixed units. The user may have data in other units, which will then need conversion.Example: Formula needs Airflow in Cubic Meters/ Minute, where as user has data in Liters/Second.I do not want to write code to do Unit Conversions from within my Program. There are readily available FREE Applications for doing the conversions. I have one such Application, which I want to bundle with my VB program.How can I Code in my program, so that when the user clicks a Button " Unit Conversion ", the bundled program will open.This is like clicking on a Hyperlink in a Program or Document and a Web Browser opens.

Alright im trying to make it where in Visual Basic 2008 you click on a box ether 10, 20, or 30. Then that tells a timer that the program needs to turn off in 10, 20, or 30 minutes. What I basically want it to do is, whenever the set amount time is when it goes off it shows form1(login form). I have prepared a picture can anyone supply me with some information on how to do this?

I have created a 7 day timer in a VB form that is to be part of a larger project. It has 14 date time pickers set to hours and minutes only in 24 hour format (1 on and 1 off per day), 7 checkboxes, 7 radio buttons, 2 textboxes to display day of the week and current time and a few buttons. As a standalone project, this works well

how to tell a program to wait or pause without using a timer control.
I did a bit of Lua scripting a few years back and the function was: Wait(5) or however long you needed the program to pause.

I want the program to exit the sub after the timer has been started. But if theres no args, it should just show itself. The problem is that it seems to not care about the exit sub thingy, cause it shows itself anyway.

I am trying to write a small program that shows a clock using a timer in vb.net, I want the clock to display the time and date as a binary display i.e. if it's 10:01:21 the clock would display boxes or buttons in rows going from 1 to 2 to 4 etc upwards and changing colour when at certain times. the example time above would be a button for 8,a for 2 to make the 10 o'clock, a button for the 1 minute and a button for the 16, 4 and 1 seconds making 21 seconds.

I was making a little timer. When the phone is not in standby, my app is working fine. But when i put the phone in standby it stops. When phone is coming out of standby, the timer is going again on the time i put the phone in standby.
I know that other tools keep working, so i there a simple way to do that?

The code in question is in place, and it works. The project is all but wrapping up. That being said, I would love to find a better way to run this section of code in an x64 system so I have the solution ready for future projects. What I currently have in place is as follows:
Function TimeDelay(vDelay)
Dim vTimmer, vTargetTime
vTimmer = TimeValue(Now)
[CODE]...
Now I know the easy way to achieve my goal would be to use the timer object in Visual Studio. The problem I ran into is I was developing an automated command line program. As such there was nothing I could attach the timer to (that I'm aware of). I just needed to pause the program for a few seconds to allow the DTSX package (SSIS file if you're not familiar) to load the file before I remove it from the staging folder.
While I was doing research for this issue I came across the old Sleep() function (referenced to a library in kernel32 as I understand it...never used this before either). When I tried to use this on my current system (64-bit system) I received stack overflow errors. Additional research lead to something called wow64, but I did not have enough time to fully research what this is / how to use it.

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.)
