Unable To Shutdown Pc While Running Program?
Jul 8, 2009
I have recently made a program but while it is running the pc is unable to shutdown, i have used the followin code, so the application minimizes while closing:
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As FormClosingEventArgs) Handles Me.FormClosing
Me.Visible = False
e.Cancel = True
End Sub
Dont know if this is preventing it 0_O??? is there any alternative to this?

I've been making a program and for it I need to be able to detect shutdown. I've been told to do vbAppWindows etc. but there's a problem. For some reason it says "vbAppWindows is not declared" Does anyone have another way of doing it?Then I've used my.settings throughout the program and it has just started to not work. It wont save anymore.

I have a Class called SocketSvr which handles an asynchronous socket server. It is called via the BackgroundWorker from my main form. Basically, I just want it to display my socket data information inside a textbox in the main form, and have a server start/stop button available on the main form to do those things.
Here is the code from Form1.vb:
Public Class Form1
Dim WithEvents Socketsvr As New SocketSvr
Private Sub ToggleServerButton_Click(ByVal sender As System.Object, _
[code]....
I am uncertain how to properly shut down requests from the client when the StopServer() function is run. In the code above, I place a cancellation queue for the background process. The funny thing is that once StopServer() is run, it will accept one more connection, then stop accepting thereafter.If I remove the following line from the code above:
listener.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, 1)
-- it crashes when I attempt to start the server a second time (complaining that I cannot reuse the socket, obviously) My guess is that I need to add something to the bw.CancellationPending call on the background worker?

I'm working on a web browser named Hyvar.NET and i'd like to integrate a form of shutdown detection into it.
Currently, it simply uses a tri-option setting to decide how it opens - like this
If My.Settings.LoadLastOnStart = True Then
frm.wbTab.Navigate(My.Settings.LastOpenedPage.ToString)
ElseIf My.Settings.HomeOnStart = True Then
[Code]....
Each variable is appropriately named for its job as you can see.
However, i want to change this to react to correct and incorrect shutdowns - unexpected and user instigated ones for example. I.E: if the settings variable for the detection contained 0x000000, it could indicate a clean exit and continue as normal with a new session, but 0x000001 would indicate an unclean shutdown and present the user with an option of reopening the last session or continueing as normal, like in IE 7/8
Im 100% sure this will require a windows API call

I made a little VB app to shutdown a laptop after it has been powered on for 2 1/2 hours, and giving the user a little over 8min warning that it is about to be shutdown. However I have nothing in place to stop the user from restarting the device once it is shutdown. What I would like to integrate in this, is a sort of memory where if the user doesn't wait at least 30 minutes, the shutdwon will re-iniate immediatly.
I included the code I did so far.
Public Class Form1
Private Declare Sub Sleep Lib "kernel32" (ByVal dwmilliseconds As Long)
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code].....

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 am designing a program that will show a reminder form when the computer is shutting down. (The reminder is to go outside and get the Bluetooth gps aerial.) I have tried using the formclosing event, (triggered by windows shutting down) to flash the form up on the screen using windowstate = normal. (At loading, the form windowstate = minimised). This did not halt windows shut down and the form was only on the screen for a fraction of a second before windows shut down. Can I trap windows shutdown until the form btn_Yes has been selected?
I think this msdn library article is talking about this. [URL]
I have looked at the enumprocess api, but this is quite a bit outside my current knowledge level. From what I have read, enumprocess would be suitable as we all run the same program on our laptops and I could check for the change of state of that program. Eg. �OK, program A is closing, the computer must be about to shutdown, so flash up the reminder form.�

I have developed a VB.Net code for retrieving data from excel file .I load this data in one form and update it back in excel after making necessary modifications in data. This complete flow works fine but most of the times I have observed that even if I close the form; the already loaded excel process does not get closed properly. I tried all possible ways to close it but could not be able to resolve the issue.
Find below code which I am using for connecting to excel and let me know if any other approach I may need to follow to resolve this issue. Note: I do not want to kill the excel process as it will kill other instances of the excel

I wrote this VB program to be able to throw a device we developed into programming mode where we use an ATMEL Flip installer to upload new firmware. I can program one device after another running the application off of Visual Studio Express 2010 or Visual Studio 2010, but when I go to publish this file and run it on another machine, it becomes unstable and crashes after each upload. On those same computers if I run the raw unpackaged program under Visual Studio Express, the system does not crash, and I can program devices repeatedly.

I recently moved my Application that was running off of Window XP and created in VS 2005 over to a box that's running Windows7.Now, when I try to debug, I can't edit. In the lower portion of the screen, it gives me this error: Cannot currently modify this text in the editor. It is read only.
Under Tools->Options->Debugging, Edit and Continue are already selected; so it's something else. Also, under project properties->compile I have it set to Cofiguration (Active Debug) and Platform (Active Any CPU).

I had the battle system 60% worked out. Went to play some Dragon Age, when I came back nothing was working as the way I left it. I don't know what happened.The richtext box is supposed to disaply the attack monster description, and then it's name, the amount of damage it does. I had it so that I could attack, be attacked, and display damage, and attack discription of both player and monster. when I opened my project to work on it again, hardly anything was working right.[code]

I am writing a program (that i have recieved a lot of help with) that creates input files for another program. The bridge between the two programs is a program that has been named the task manager as like the windows task manager it shows what tasks are being done/have been done/are about to be done (or executed)
What i would like to know is how can i run the already installed bridge program from my program? Do i need to run it by opening the executable that contains it? Or by declaring the bridge program as a type/structure/class and going from there to open it?If you're not living on the edge, you're taking up too much room

I am trying to startup a simple VB.net program that has a GUI from a service. I have tried a few flavors of Process.Start and none of them allow the GUI to work. I can get the farthest using:
System.Diagnostics.Process.Start(
"C:ProgramDataWatcherStartIt.bat")
And from inside the batch:
start C:TestTestStart.exe
Eventually I get an "Interactive Services Detection" dialog telling me that a message is trying to be displayed and when I click View the message, I see my expected dialog but the program won't run. I am Running on Win7 Home 64 bit. My Simple GUI program was written in VB.net VS2008. I set the service properties to "allow interaction with the desktop" but this does not help.Is there any way to launch a program from within a service that will allow you to interact with the desktop?

Although I signed up a year ago I didnt have enough free time to carry on programming, but have now made some time.
I have spent the past 2 hours trying to look for a code for visual basic 2008 that will check if a program is running.
It would be really helpful if someone wrote the whole code out and made it clear exactly where I put them name of the .exe file
