I cannot get process.start work now. I have tried wrapping it as a call outside of my class, but it doesn't matter...it does absolutely nothing.No error msgbox either...
Heres my code
Private Sub mnuWizard_Click(ByVal Ctrl As Microsoft.Expression.Web.Interop.Legacy.CommandBarButton, ByRef CancelDefault As Boolean) Handles mnuWizard.Click
''''''''''''''''''''''''''''''''''''
'Handles Wizard Click Event

My project requires that a windows service checks up a table on a sql database(MDF) and if product existence is 0 then sends an email to some mail address and keep checking every 24 hrs.Now Im able to send mail messages but what Im not able is to make the service itself to work or at least make sure that is working.I do the following(correct me if I do something wrong or missing a step):
1. create a new project and choose windows service
2. add a timer and set to 4000 ms just to test not wait the 24 hrs lol
3. then open its event timer_elapsed and put some code on it, like a msgbox that would keep spamming every 4 secs just to test
4. at the event onstart I enable the timer by: timer1.enabled=true
5. at the event onstop I disable the timer by: timer1.enabled=false
6. right click then choose add installer
7. in the newer installed with the two objects:
a. serviceinstaller1 set its properties to: displayname: myservice and servicename: myservice
b. serviceprocessinstaller1 set account property to LocalSystem
8. build the project and install it by opening the VS console and type: "installutil c:path blah blahservice.exe" then hit enter
9. all successfull installed open the pc manager and run the service from the list and this should be the deal
Now my real problem is that by following those steps my service is sucessfully builded, installed, and started but after the 4 seconds no msg pops up so this leads me to think that is not doing anything or I did something wrong in the steps above. Is there another way to test if this service is working else than the msgbox or the log entry? Plus, Im working on my home pc which is a xp OS. I tried the same at college pcs wich are win7 and when I did install by the console it returned an error weird but in my home pc it doesnt(and I have to present my project at college at college and tomorrow

I have a vb.net 2008 application that is supposed to run at startup. After meeting certain conditions, the PC is supposed to restart. Below is the code that is failing:
System.Diagnostics.Process.Start("shutdown", "-r -t 00 -f", myUsername, myPassword, myDomain)
myUsername and myDomain are both strings while myPassword is a SecureString. The application works properly when execute manually, but give the following error when executed from startup (either by placing in the startup folder or by adding to the registry):
The directory name is invalid
Also, the program executes properly when the last 3 arguments are left out and the user has the necessary rights.
How do I force a restart using an specific, alternate user credentials on startup?

I have created a Form, added a MenuStrip to it and inserted the standard Items. My question is that I know some of the options won't work like 'Save' and 'Save As' but how do you make ones like 'Open' 'Exit' 'Undo' and Redo' work when start debugging?

I'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.

Visual Basic 2010 - Net Framework 4.0 Client
I have an application (application #1) running with Administrator privileges on Windows 7.
I want application # 1 to start another application (application #2) without Administrator privileges so application #2 is running as a standard user.
Is there a way to do this? I have been using Process.Start.

Here's what I currently have:
[Code]...
I've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.

My app starts an On-Screen Keyboard process like this:
Dim PID as System.Diagnostics.Process
:
PID = Process.Start("C:WindowsSystem32osk.exe")
:
[CODE]...
It seems to work 90% of the time. However, sometimes the PID.Kill() fails because it says the process already exited. At this point the OSK is always still there on screen. Yes, I know my code should be testing to see if the process is still running before trying to kill it, but given that the OSK is still on screen..

I have a program that starts another program after setting the regkeys basically the program continually syncs the calandar of outlook and another application.I set the regkeys than launch the c:sync.exe app. I have tried a simple process.start and launching the process as a thread and they both do the same thing: The other process starts and works as it should but my main program goes "White screen" or "not responding" until the process.start has exited.
I want the process.start to run in the background so if users click in my main app it responds and truly that they can access the context menu of my main app from the taskbar while the process.start is running.

I am using a backgroundworker to start ffmpeg and trying to use a progressbar.ProgressBar1.Value = e.ProgressPercentage does not seem to work probably because the way ffmpeg uses standard error to report progress. I think i could use the output text to do the trick. the output.Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 29.92 (359/12) [code]

i've got a problem here whereby my ctype doesn't work.firstly, to replicate my case briefly, i've created an extension of control class
[code]...
father.getheight 'compiler writes: Panel class doesn't support getheight, but I've already converted it to a Control with CType!end sub of course if i dim father as Control it works perfectly, but in my case father may be other objects as well that aren't controls so I had to dim father as a general object, is there a fix so i could properly convert father into a Control object?

I am writing an application that in the end needs to execute another executable at some point, the problem is that the executable has dependencies in the directory it runs in that are required to operate. When I use the Process.Start to run the executable it errors out because it's looking for the dependencies in my applications directory.
I tried the startInfo.WorkingDirectory option but that didn't seem to do it either (not sure if I did it right) - here is how I used that:
Process.Start("my.exe").StartInfo.WorkingDirectory = "C:Test"For the life of me I cannot find how to set the "Start In" directory. I looked everywhere, so unless it's under a different name, I'm at a loss.

I am firing a threaded process using (checkfile is my sub):
mythread =
New System.Threading.Thread(AddressOf
checkfile)
mythread.Start()
THe problem is that it doesn't seem to be working the way I anticipated. Whilst the process is actually being run in the background, the main UI is just frozen. This is highlighted by the gif animation i wanted to have animating (eg. like a ticker) whilst processing, actually coming up as a static image. As soon as I click anwhere on the UI i get the "Not Responding" message at the top, plus the button that executes the thread still seems to be depressed and has the orange glow around it.

I'm using the IsBusy property to determine when a backgroundworker has completed. In the RunWorkerCompleted event I assing the result of the RunWorkerCompletedEventArgs to a public variable within the module where the backgroundworker events reside. The trouble is, the IsBusy property occasionally becomes true before the public variable gets assigned the value of the RunWorkerCompletedEventArgs. I experimented with putting a Threading.Thread.Sleep(10) after the IsBusy property becomes true and it seems to fix the problem. But it really doesn't seem right that I should have to do this. What is wrong here? I have placed the backgroundworker events in a component that is instantiated from the windows form, instead of placing the background worker events within the code of the form itself.
Here is my code;
Function SendAndWait(ByVal IntegerArray() As Integer) As String
Component.BackgroundWorker.CancelAsync()
Do While Component.BackgroundWorker.IsBusy

I'm working through a programming project, which should be quite easy but im stuck right at the start (relatively new to VB). I have a textbox (named textbox1) and a checkbox next to it. I want the checkbox to be ticked (.checked) when ever the value in the textbox is between 1 and 100, the checkbox to not be ticked when theres nothing in there, and for it not to be ticked when the value is < 1 and > 100. Figured a case statement would be the easiest. (this piece of code is just a validation check, basically in the real thing the user would have to enter in a value between 1 and a given number, and need to tell the user if that value is valid).
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
Select Case TextBox1.Text
Case Is = ""
[code]....
But what happens is, if I enter in the value 1 in the textbox, the checkbox becomes ticked, as it should. It tick with any values between 2 and 99 (any number not starting with 1) but the checkbox becomes ticked again when the value is 100. For any other range, say 1 to 70, the checkbox would be ticked if the value in the textbox is 1 to 7, or any number starting with 1 or 7, but not 8 or 9, or any number starting with 8 or 9.
