Calling .dll Method From Inside A Timer Won't Work(Console Application)?
Nov 26, 2009
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'm working on a Java app wich uses the CMD.i want to control the app completely though a forms application and so i created a invisible CMD console that starts and runs,the only problem i keep getting. is that after startup and further commands send to the CMD window doesnt work. not commands are received.heres my code
the basic functions
vb.net
Private WithEvents MyProcess As Process
Private Delegate Sub AppendOutputTextDelegate(ByVal text As String)
Private Sub MyProcess_ErrorDataReceived(ByVal sender As Object, ByVal e As System.Diagnostics.DataReceivedEventArgs) Handles MyProcess.ErrorDataReceived
AppendOutputText(vbCrLf & "Error: " & e.Data)
End Sub
Private Sub MyProcess_OutputDataReceived(ByVal sender As Object, ByVal e As System.Diagnostics.DataReceivedEventArgs) Handles MyProcess.OutputDataReceived
AppendOutputText(vbCrLf & e.Data)
End Sub
Private Sub AppendOutputText(ByVal text As String)
If outputtextbox.InvokeRequired Then
Dim myDelegate As New AppendOutputTextDelegate(AddressOf AppendOutputText)
Me.Invoke(myDelegate, text)
Else
outputtextbox.AppendText(text)
End If
End Sub
the startup that works.
VB.net
MyProcess = New Process
With MyProcess.StartInfo[code].......
i sometimes replace the textboxx2.text with a custom command like "exit".so when i press the button after entering exit for example nothing happens.but when the app starts it does gets the first 2 commands. so why is it failing at the buttons.

Everything is nice and dandy on my pc, then I compile, move it to its final destination and I doesn't work! At first I thought it was a OS problem, but both machines has win7, I then thought it was a compilation problem, installed visual studio on the other pc, recompiled still with no luck, then it dawned on me, may it be a problem of 32bit vs 64bit?The piece of code is this:[code]....
By the way is not a problem of mouse_event, is the timer that doesn't work

When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it.It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is:
First: "PerformLookup Time: 40:842"
Second: "initIndex Time: 45:873"

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 am coding in VB.Net, VS 2008. I wrote a console app that consumes 2 web methods from a web site application. I need to enhance this console app so that it launches the web methods continuously, perhaps every x minutes (during business hours), but never before the last invocation has terminated, whose duration may vary, depending on how many accounts there are to process.
Originally, I scheduled the application using Task Scheduler, but I think this doesn't prevent two invocations at the same time.
Although I have seen many posts on using timers, I haven't found exactly what I need.
So far I have:
Dim aTimer As New System.Timers.Timer()
AddHandler aTimer.Elapsed, AddressOf TriggerWebMethods
' Set the Interval to 10 minutes:
[Code]....
When should Timer.Elapsed be used vs. Timer.Tick? What is the difference between Timer.Enabled vs Timer.Start, and should I be selecting just one? I would like the 2nd web method to kick off when the first one is done.

i am trying to understand how to keep my console app open even after it gathers data and sends it off. I am converting a GUI to the console app. It has a timer that fires the sub every 20 seconds. But it doesnt seem like it works in the console app since after it fires off the sub it closes the app without waiting.

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 am currently working on an application, where I am using a console application, that will set up the application prior to the main form is run. This is no problem I've got that all working perfectly, the only problem I have is that the console is showing while the application is running, I was wondering whether anyone knows any way in which I would be able to hide the console before it gets shown to the user.

How do I get the console from closing immediatley upon opening in a Console Application program? I have all of the code written but when I run the program it pops up the console window and then immediatley exits so I am unable to read what is in the window to see if my program is operating correctly. This is the first time I've ever used a console window so I don't know where in the code I would need to put "whatever it is" I might need to put to keep the window open until closed by the user.

It sounds confusing but it's not really. What I need is basically a way to emulate the console style text, without using a console. What I'm really doing is trying to do a matrix effect on my form background, by drawing symbols and moving them, alternating their colors (see this video for what I mean).
Is there a way to do this effectively with a timer and a draw event, with the timer calling the draw event and changing the intervals?
