you can get a lot of result if you Googling
you can also find a lot of articles on code Project

Hi,
easiest way is using SystemInformation.ComputerName and Environment.UserName
Isn't Google working where you are?
|
|
|
|
|
To Get the Systen name if Current Login name we use Environmental Variables, this is Simple.
String strloginname = Environment.UserName.ToString();
String strComputername = Environment.MachineName.ToString();
MessageBox.Show(strloginname);
MessageBox.Show(strComputername);
There are a lot of Answers in Google, you should teach your self to research before you ask.
Hope this Help

Hi,
I have a main startup form called MainForm and I declared an instance of a class that launches a timers.timer that needs to update the MainForm controls (textboxes, progressBars,...) so I created the following delegate in MainForm:
Public Delegate Sub updateMainForm(ByRef neededChannel As Integer)
and the following call from the Timers.Timer.Elapsed event:
mainForm.Invoke(New mainForm.updateMainForm(AddressOf mainForm.determineIfKeepInAllOrIndividualChannel), New Object() {currentSTATE.CHANNEL})
and I get this error:
An error occurred creating the form. See Exception.InnerException for details. The error is: Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.
I looked into the error and they recommended putting a <STATThread>_ in the Main function but I don't have a main function. If there is a better way to communicate with the MainForm from the Elapsed event then that is fine as well. I'm looking into starting the Timer from a BackgroundThread and keep it alive with Monitor so that I can utilize both ProgressChanged and WorkCompleted, but there must be a simpler way.

Hi,
seems like you are using some component (a separate DLL?) that needs the thread to be STA.
(what are those channels?)
A Timers.Timer will fire on a separate Thread of which you don't have control.
The easiest fix might be to switch to a Windows.Forms.Timer, which ticks on the GUI thread,
which by default is STA IIRC.

I looked into the error details and it came out with this:

When I open the admin form from the file menu of the main form then close the admin form and open it again I get a binding error.
Here is the error. Why am I getting the error?
This causes two bindings in the collection to bind to the same property.
Parameter name: binding

|
|
|
Since none of us have any idea what the admin form and main form are, perhaps you could provide us some more information. What code are you using to open and close these forms?

There is one thing that we cannot understand in your Situation, is because we dont see your code, and that means we dotn know what you are talking about, if you can show us your code it would be better

Hi,
I am trying to read some system config from the registry. The config info is stored as a binary value of type "REG_RESOURCE_LIST".
If I try read this value with o=registrykey.getvalue(), (with o being an object), o will be set to nothing.
I can read a string key from the same group using the same command, and it works. It just always seems to fail on binary keys.
The "GetValueKind" of this key type returns Unknown.
Any idea what I am doing wrong? I've been googling for what seems like all morning, and I cant find a solution.
[Modified to sort out a typo]

Hi,
the RegistryValueKind Enumeration lists all data kinds supported by .NET, as well as Unknown for
all the other ones. So you're out of luck. I suggest you use P/Invoke and call the Win32 functions
directly (as was needed for all kinds other than REG_SZ before .NET 2.0).

I was hoping not to have to do that.
Oh hum.
Thanks for the reply - at least it puts my mind at rest that I have not gone crazy... (I am just slowly on my way to being there! )
Thanks.

Hi,I am using vb.net to create an windows form application.
Does anyone know of any articles/ideas that could help me in adding textboxes or combo boxes to a listview?
Basically what i want to do is edit the data in the listview and it should save once i click out of it.
Thanks

Have you googled or codeprojected? It seems like I've seen hundreds. In .NET 3.+, you can do it also through WPF.

Write a vbscript to do what you want and use Windows Task Scheduler to schedule the script.

Hello everyone,
I'm very new to VB6 and I've been blessed to be the fall-out boy for creating this system that SHOULD connect the application to SSH giving me control using UNIX functions. My question is...how do I make this possible. I'm pretty much clueless about this. Many many thanks for all your suggestions.

You'll need a 3rd party component to handle the ssh connection. There's one at http://www.ssh-activex.com/[^] that has a free version available. I don't know what the limitations are in the free one.

Great! Exactly what I was looking for. Many thanks friend

I feel sorry for you. VB6 has been dead/unsupported by Microsoft since March 2005. You may want to become more familiar with VB.NET/C#, just a friendly suggestion

I'm actually quite familiar (but not near an expert) with .NET framework although management requires me to do this using crappy vb6. This app is actually like a trouble ticketing systems that allows certain users to display records, validate codes etc and provide resolutions. Problem is the records are not really database driven...rather file based using SSH. Yeah I know...problematic either way
