View 8 RepliesIm working on an AutoUpdate class for a small application I've been working on, and with Windows 7 and Vista machines I get a permissions error when trying to replace some of the files in the Application folder. The only way to get it work is to run the application as an administrator. Is there a way I can either attempt to automatically run the app as administrator, or a way of replacing the files that won't be blocked by Vista/7's permission gatekeepers?

BTW this is VB 2008 I don't know if 2010 is any different codding than 2008.
I have a task that needs to be executed many times in a thread, so as to keep my GUI responsive. Right now I'm using the ThreadPool to accomplish the tasks, and it works perfectly. I get all the data I expect back from the threads, life's good. When those tasks are finished, I then fire off another set of threads to accomplish another set of tasks, in the same fashion. The work method of these threads uses a call to RegistryKey.OpenRemoteBaseKey, which does exactly that, opens a remote registry key. The problem is: if the user running the application does not have permission to open the remote registry the call will throw an IOException, but I expect this behaviour because the user does not have permission to do it. However, the call itself can take FOREVER.
I wrote the application initially to use delegate methods and used the WaitHandle.WaitOne() method on AutoResetEvents in a state object I passed to each delegate. I tried the WaitOne method using a timeout, which worked fine until I realized that even though the WaitOne timed out, the thread was still running. This is a problem because (from what I understand) processes are only given a certain number of ThreadPool threads and, once used, they must be finished in order to be released back to the threadpool. In my work method, I also have a variable that can be signalled when the thread should be stopped, but that (obviously) only works on code that I've written.how can I cancel a thread that's stuck on a .NET method? Is there some sort of garbage collection method I can call if I give it a handle?
How do i check if specific port is blocked by Windows firewall , both in incoming and outgoing connections.
I've seen code samples such as this one:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim host As String = "localhost"
Dim port As Integer = 6900
[Code]....
But how can i know if the exception is thrown specifically because of firewall blocking, and not because of other socket errors?
I am making a banking system in Vb.Net but I had a problem with this function. If a user fails to input the pin number for 3 times, it will be block automatically and will need the admins permission in order for that person to activate the account again. I really don't know how to code the blocking of account and asks for admins authorization to unblock the account again. By the way I'm also using MsAccess as my database for my Bank Simulation.
View 5 RepliesI'm having a little difficulty sending mail using VB.Net (2003). I'm attempting to use the company mailhost, and the usual System.Mail methods to do the send, but i get blocked by the "Could not create CDO.Message" error. I've been on MSDN, and looked through the various threads on here, and they all point to a problem with the dll.
The trouble is, that this is not a consistent error. Sometimes it works, sometimes it doesn't. It will work on one user's PC profile, but not another's on the same PC. It will send a mail for a particular user, and then 2 mins later fail to send the same mail. I've tried re-registering the dll anyway, and faffing about in the registry as per the MSDN recommendation, but no joy. And because it's so inconsistent it's proving pretty tricky to narrow down the cause.
I'm calling the following method from a button click event to export a datatable to excel. After the export is completed, the excel application object is quit, released and assigned to nothing. But in reality it's not getting released and stays active unless the entire application is closed. So every time the button is clicked for export, a new excel application object keeps on running. The problem doesn't occur if two of the lines from the method below are not used. But I can't omit them as they are really needed. Check the * marked lines.
Code:
''' <summary>
''' Exports data from a datatable to excel.
''' </summary>

Where in Visual Basic 2008 Express Edition Software program do you specify a specific installation directory for a program?
c:Program Filesfinished program
I want to publish my program to try it out on another system and I want to ensure its installed in the directory structure I want.
i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.

Is there a way to validate a groupbox with a couple radiobuttons in it to make sure that one of the radiobuttons is selected?
Heres why I need this. I need a user to be able to select their class rank out by way of radiobuttons in a groupbox. When they click submit, I need to validate that atleast one of the radiobuttons got selected and if not display a messagebox.
I got one reply early of:
If myGroupBox.Controls.OfType(Of RadioButton).Count(Function(rb) rb.Checked) = 0 Then
'There is no RadioButton checked in myGroupBox.
End If
Is there any other ways other then that? Preferrably a more 'dumbed' down way? This is for just an entry level VB class, I would prefer not to use something of that nature if there is another way.
I am running a program that is connected through the internet and i gets disconnected at times.wanted to know how this would be to examine a color of a pixel , If the colour turns changes, my mouse will move to reconnect

View 1 RepliesI have been working on an app that was basically a vb6 app but had to be changed and I did it all using VB 2008. works well, great. One of the problems that I had was to work on different groupboxes or frames. Since they are layered on top of each other, working on one frame would mess up the others. Eventually it all went okay. but now if i want to add another item in the menu and hence add another groupbox (or frame) in the same app - it would definitely be a nightmare.

I recently created a very simple project in VB express 2008 to interface with a COM object from an external vendor. I then downloaded the VS2008 90 day trial and found that the identical code in a VS2008 project results in a COMException error "Object is out of scope". Is anyone aware of any differences in how the two packages handle COM object interfaces as I have run out of ideas. Both projects have identical code and all the references are the same. The CreateObject() method correctly creates the object, but any attempt to access methods inside the COM object result in that error. I can even open the VB 2008 Express project inside VS and it still generates the same error.
Here is the code - the vendor dll in question is from Siebel v8.0.0, you'll notice that I have commented out most of the code that comes after the error. Creating a watch in the debugger on the siebApp variable sees it correctly created as {System.__ComObject}type SiebelHTMLApplication. I first tried this by creating the Property Service for variable siebSvcs, but after I started experiencing the COMExceptions, I reverted to using the most basic method inside the COM object I was creating.
