How Can I Cancel Axinet1.openurl Process
Sep 24, 2009
I am using inet object and trying to get web sites' html source code.It usually works but in some sites openurl process is very long.So i decided to cancel axinet1.openurl process after 5 seconds and tried timer object. In timer tick i used axinet1.cancel command but it doesnt work :S Also i used timeout function of inet object but if it is small amount ,for example 5 , there is hresult 0x00 exception. So it doesnt work too.[code]

When a large image is loaded into a PictureBox, sometimes the process takes way too long. How can I cancel this? Is there anyway to use a keypress or timer to cancel an image from loading? I'm working locally, not loading images via http. I've looked at Application.Events, SystemArgs, DoLoops - nothing seems to address my need to kill the specific picturebox load process.

I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.

I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

I want my vb.net dll to get the data sent from c++ project(exe).Can any body help on in what form this void pointer can be sent via pipe. The void pointer corresponds to enums or structures. I have to get this structures/enums on the vb.net dll end. I have mentioned about using pipe. My question is as what type the pointed to data can be send over the pipe so that I can easily handle the received data at the vb.net dll end.

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 working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")
[Code]......

I have an issue using Process.MainWindowTitle,Process.MainWindowHandle on some older VB6 applications. After Process.Start I use Process.MainWindowTitle to display in a listbox. The MainWindowTitle returned is not the Window Title but in fact the Project name of the VB6 exe.? I also store the MainWindowHandle to use the ShowWindow and SetForeGroundWindow API's. It would appear that the ShowWindow API does not work, but the SetForegroundWindow does. ie: if the VB6 app is minimized, showwindow does not restore, if it is NOT minimized setforewgroundwindow sets it to the foreground. The exact same code does work correctly for any other .net exe or notepad, only on these vb6 programs I am having a problem.

I was wondering if this code could be better optimized for multithreading. What it does is open a process and loops through the data, there could be any range of files to open (so I would like to have say 2 or 3 processes at once):

I have a procedure (parent process) that starts several processes (child processes). The child processes calculate several array variables. How can I pass those arrays to the parent process? At the moment, the child processes write the arrays to a streambuilder and the parent process reads the stream. Is there a better way to do it? Is it possible to have the child processes write to RAM memory and have the parent process read from there? It is like declaring a global variable in the parent process and give the child processes access to it.

How can i access a file through FileStream which is being used by a window service. Actually i am trying to access a file which is also being used by our window service. I need to read data from this file. I am using below code but also getting following error:
Code:
Dim fs1 As IO.FileStream = New IO.FileStream(psPath, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
Dim sr As IO.StreamReader = New IO.StreamReader(fs1)
sData = sr.ReadToEnd
Error: The process cannot access the file 'FILENAME' because it is being used by another process.
I tried changing FileShare.Read parameter to FileShare.None but it didn't work out. I also read below post which says that it is not possible but i think there is a way to read it like if you open a file through Firefox but still window service is accessing it.

VB.net 2010 Read all around the net, but cannot seem to do this: Tried the performance counter Categoryname=process Instancename=("program"). _Total helps in part- but it would be more efficient to acquire the main applications cpu usage for this project.
Code:for each p as process in process.getprocesses if p.id=process.getcurrentprocess.id then end if next 'Values, Obviously multiple processor cores have to be taken into account'kernelmodetime, usermodetime, Cputime, total cpu time, 100% <-- Does this involve adding and or dividing all these times? I need the current process CPU usage.

The process cannot access the file 'C:UsersJoshuaDocumentsTest1.txt' because it is being used by another process.Now the Problem. When i step through my code, it will do as intended, e.g. clear all contents of test1.txt. when i run it at run time it throws this error. The reason for it throwing an error is the text file is reading string, int, string, and the txt file has a string including in the int part, so i'm making it so you can empty a corrupt file.

This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":
Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)
[Code]....
In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.
