Hi all,
i am pretty new to VB and i got one problem for which i can't find any answer (sorry if i'm simply too blind and this was already answered). Maybe i also start with too difficult issues.
Anyway, i'll just ask.
Is there any way to access the properties of a service and to display these information in a ListView?
In more details:
I got an application developed as a Windows Service. This application can be used several times as a service which means several instances of this service can be created.
My problem is that i would like to display the path the original exe-file of the according service/instance in a ListView.
I already managed to get the name an current status of the according service but i can't manage to display the according path.
I'll put a part of the code here (please be forbear with me i'm beginner):
--------------------------------------------------------------------------------
ListView is called LstGenvSrv
'List
LstGenvSrv.View = View.Details
LstGenvSrv.Clear()
'Columns
LstGenvSrv.Columns.Add("Service", 300, HorizontalAlignment.Left)
LstGenvSrv.Columns.Add("State", 70, HorizontalAlignment.Center)
LstGenvSrv.Columns.Add("Registered File", 350, HorizontalAlignment.Left)
Dim RunningServicesXXX As ServiceProcess.ServiceController
Dim ServiceList As ListViewItem
For Each RunningServicesXXX In ServiceProcess.ServiceController.GetServices()
If RunningServicesXXX.ServiceName.StartsWith("XXX Service") Then
ServiceList = New ListViewItem(RunningServicesXXX.DisplayName)
ServiceList.SubItems.Add(RunningServicesXXX.Status.ToString)
I played around here but i am not able to... 
LstGenvSrv.Items.Add(ServiceList)
LstGenvSrv.Refresh()
End If
Next
--------------------------------------------------------------------------------
In Column "Registered File" i'd like to display the path to the original exe-file for a better overview.
Is this easily possible? The only other possibility i know is by accessing the Registry. Searched through all items of ServiceProcess / ServiceProcess.ServiceController but did not find anyhing.
Some person told me to use some API-Functionality but i thought with .Net this is more or less obsolete.
Thanks for your help.

Can you tell us what the error is? Knowing what exception was thrown and the message helps a lot in determining what the error is so that a solution can be found.

|
|
An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in system.data.dll"
this error occur
|
|

I'll repeat my request with the important bit highlighted: Knowing what exception was thrown and the message helps a lot in determining what the error is so that a solution can be found.

What do you mean with a "hyperlink text"? Is that a label that is made to look like a hyperlink, or should you have asked this question in the Web Development forum instead?

how do i start a timer from the toolbox and how do i declare it.
|
|
|
|

your question is very confusing...what do u mean by
start a timer from the toolbox ????
whatever.....you can create a Timer in runtime........like this
1.declare a Timer variable like this......<br />
Private WithEvents myTimer As Timers.Timer<br />
<br />
2.write a function SetUpTimer() like......<br />
<br />
Public Sub SetUpTimer()<br />
Try<br />
myTimer = New Timers.Timer<br />
With myTimer<br />
.AutoReset = True<br />
.Interval = 1000<br />
.Start()<br />
End With<br />
Catch obEx As Exception<br />
Throw obEx<br />
End Try<br />
End Sub<br />
3.Wherever you want your timer to start working call SetUpTimer()

Hello,
[VS 2005]
Using typed dataset
I have a table adapter that is filled. I want to delete all the previous data that is in the database before filling this table.
Is there a single command that can be used to delete every single row in the database table, then issue the fill command.
With the delete command you have to enter the fields. However, I don't have the name of the fields values until after the table is filled.
Just want to fill the table with fresh data.
Many thanks,
Steve

try this.
[DatasetName].Tables(0).Rows.Clear()
the zero value pertaining that you only have one table in the dataset.
hope this hepls.
|
|
|
|
|
I would suggest that you can go ahead and write a SP itself that deletes or truncates the table entries.
You can call this SP from TableAdaptor followed by this use the SP to fill the table

Hi,
I created a database that store the chinese character in mysql. When I retrive these data by :
SELECT * FROM table_name
and display the data in the listview in vb.net, the data become ???. Anyone can help me on this?
Thanks.

Well, characters in .NET are saved as Unicode Big Endian, which contains almost no Chinese characters, so the problem should be to encode the characters as UTF8.
