I am having a problem with this:

So the below code is supposed to loop through all the processes and fine all those who's title contains "eReceipt". I want it to report the number in OpenReceiptCount.What it does however is only return 1, no matter how many are open. the titles are all very idential aside from a receipt number. And I can see each processes show up with a title that DOES contain eReceipt (hence the messagebox) but after it counts the first one and sets OpenReceipt from 0 to 1 it will not count any others.
Dim OpenReceiptCount = 0
I am fairly new to VB.NET (but have vast professional experience with several other languages) and am completely new to these forums (so please don't burn me if I posted in the wrong place). I have run into a rather odd quirk with System.Diagnostics.Process.GetProcesses. I have a sample application (source posted below) that checks all running processes every second for changes (created and destroyed) and tells the user what has changed, if anything, in the last second. The sample runs for anywhere between 29-72 seconds before issuing an array out of bounds error. It appears that the Windows system processes, SearchProtocolHost.exe and SearchFilterHost.exe explicitly, disappear from the list causing my application to throw the aforementioned exception. Specifically the exception I am receiving is as follows:
Unhandled Exception: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.I have noted in comments where the exception is thrown in the code below. If any of you would be willing to try this sample on your PC's or could suggest potential issues with my sample that could cause this problem
My sample code:
Imports System
Imports System.Diagnostics

I am iterating processes using the Process class GetProcesses method. I would like to display information formatted similarly to the way the TaskManager displays it. Where to I get the CPU and Mem Usage data that the TaskManager displays?
View 2 RepliesWe needed an inter-process reader/writer lock.We decided to use a file and lock the first byte using LockEx and UnlockEx. The class creates a file in the system temp folder when it is created. The file is created with readwrite access and share read|write|delete.We also specify DeleteOnClose so we don't leave loads of temp files laying around. Obviously AcquireReader and AcquireWriter call LockEx with appropriate flags and ReleaseLock calls UnlockEx.We have tested this class using a small application that you can run several instances of and it works perfectly. The application that uses it has a problem, which we have managed to re-produce in another small test app. In pseudo code it is
Create InterProcessReaderWriter
Dispose InterProcessReaderWriter without acquiring any locks
Launch a child process which takes a reader lock
The first time this runs, it works fine. If you attempt to run it again, while the child process from the first time is still holding the lock, we get an UnauthorisedAccessException when trying to open the file.This appears to be a permission issue, not a sharing violation but all the processes in this test case are running as the same user.
I thought I postet this yesterday but I can't find my thread so if this is a duplicate please point me at the original one. Background: I need to create a user account and Modify it's registry before the user logs on the first time. Creating the account is done by using the Winnt provider (works great). To create the profile I'm trying to use Process.start to launch a process as the newly created user. With the use of loaduserprofile property the users profile gets created and i can do my regwrites without problem.

Start a process from vb with administrator rights?
View 13 RepliesBackground: I have 2 Apps. One spawns the other as a 2nd process. Both need Adminstrator rights to run.The below code (which spawns the 2nd app from the 1st) works just fine from my released Application (when I right click the 1st app icon and start as Administrator).
Problem is, from within the VB Express environment it does not. The 2nd app starts, then complains about Access Rights.Can I start a process with Administrator rights in Windows 7 from within the environment?

I created a vb application and I'm trying to deploy it. However, it needs to be run as administrator, which is not ideal as several machines I'm deploying it to can't access the administrator account. The odd part is that the development environment isn't on an administrator account. When I double click the compiled executable it runs fine. When I right click and choose Run As Current User the program crashes and gives me the same error I got when trying it on the target machines(without access to the administrator account.)

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.
Our application needs to communicate with another program through a COM interface. The interface will not work if the other program is started with "Run as Administrator". Would like to detect if this other process is in this state and warn the user.
View 2 RepliesI have a VB6 application which has been running succesfully for years under XP, however under Vista data loss has been observed.It appears that if the app is run 'as administrator' then it connects to the correct database file, however if the app. is not run as administrator then vista creates a copy of the database (no idea where) - hence I end up with 2 versions of the database.
In fact I can delete the database file entirely and the app. still works fine because vista is using it's own copy - the problem is how do I back up this 'vista copy' when I can't find it (search doesn't find it).
screwed up User Access Control, some functionality does not inherit the accounts true privileges. I built a Command Prompt application and ran it from an Admin account, but I kept getting access denied when I ran it. The only work around I can find for now to shut the dam thing off in control panel.
