I should ask. Are you familiar with things like file streams? If not then my example isn't going to make any sense.

I have written a utility that displays runing processes. The only problem that it doesn't show if I have windows explorer open in the process list. I've nnarrowed the list down to show applications that are currently running, but doesn't show any instances of Windows Explorer.
Thanks for your help.
I am always greteful for any help!

Well, without knowing anything about how you're enumerating the processes or where you're getting your information from, it's pretty impossible to tell you what you're doing wrong.
For soemthing like this, I'd probably use the Process class and it's GetProcesses method. This will return all running processes, including explorer.exe.

Thanks Dave,
I've been using the Process class and the GetProcess method. This works well but doesn't list a separate process if I have windows explorer open on a certain directory/folder. I'm trying to list all running applications including any instances of windows explorer and the folder/directory that it is pointing to.
I've read somewhere that the listing of windows explorer is a top-level listing and that is why it doesn't appear in running process.
Thanks

Those are not seperate processes. Each is a window belonging to a single instance of explorer.exe. You have to enumerate the windows using the Shell.Application COM object and it's Windows[^] property.

Thanks Dave, I'll give it a go and let you know.

Sorry Dave but I've looked everywhere for the Shell.Application COM object in Visual Basic 2005. Can you please help me to locate and use this object?
Thanks again

You need to be adding a reference to "Microsoft Shell Controls and Automation". Or just add it to the .DLL directly, C:\Windows\system32\shell32.dll.

Sorry Dave, I've added Microsoft Shell Controls and Automation, then Imported shell32 namespace.
I wrote a test code to view the application windows that are currently running as follows:
Dim shlApplications As Shell
Dim obj As Object
shlApplications = New Shell
For Each obj In shlApplications.Windows
MsgBox(obj.GetHashCode.ToString)
Next
The only problem is that it is not returning the name of the application(s) that are running.
Can you help please?
Thanks

There are lot of free or trial database converters available on line..
If u are not getting a direct one then at least u can convert it to something other DB and then from there convert it to foxpro..
Good luck

I was on the MSDN web site and found a function that is useful to me. Here is the function.
Public Function SelectRows(ByVal dataSet As DataSet, ByVal connectionString As String, ByVal queryString As String) As DataSet<br />
Using connection As New SqlConnection(connectionString)<br />
Dim adapter As New SqlDataAdapter()<br />
adapter.SelectCommand = New SqlCommand(queryString, connection)<br />
adapter.Fill(dataSet)<br />
Return dataSet<br />
End Using<br />
End Function
Is the SqlConnection function a function that is in VB.NET or is this something I have t6o write?
When I was on the MSDN site I saw a Sql Connection Class, but am not sure if it is a class that the VB.NET program will write for me. Is it possible that it did write the function for me but it is called something different or is it in a namespace?
Here is the url where I got the code. I am getting the blue line under the SqlConnection function call. How do I fix this?

IIRC, it is in the System.Data.SQL namespace or something like that.

I need to re-select the current record after a user clicks a column header to do a sort. This needs to be done after the sort. All of the references I have found say to add a handler for the DefaultView.ListChanged. I have done this, but I don't get the ListChanged event they say I should get when the user clicks the column header and the sort is performed. I have tried using the mouse up/down events but the sort is not performed until after the mouse button is released. I need to do something after the sort. Am I doing something wrong? This is the code I use for the handler.
AddHandler dsInvoice.Tables("Invoice").DefaultView.ListChanged, AddressOf onListChanged

I'm trying to validate a textbox with only a...z and spaces. I can validate a...z with Keypress but how do I validate a space?

The SPACE character has an ASCII code of 32. Cast the KeyChar property of your KeyPressEventArgs object to an int and check whether its value is 32.

I would always use Keys.Space, and not a space or ASCII code. I would use char.isalpha to test against a-z, also.

another technique:
Private Sub Txt_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Txt.KeyPress
If Char.IsLetter(e.KeyChar) OrElse Asc(e.KeyChar) = Keys.Space Then
'allow
Else
e.Handled = True
End If
End Sub

I am using VS 2005 .NET 2.0
I have added a application config file, which contains 2 keys for my application. The config file named appTextSearch.config is created in my application's folder.
Now, the problem is I am not able to read these 2 values from the config file.
serverDetails (see below) returns nothing
ConfigurationManager.AppSettings.HasKeys also returns false
DO I need to specify anywhere in my application to read this application config file ?
</configuration>
<appSettings>
<add key="servername" value="http://a2tmon963:9080/gisgazetteerhttp/addressformatted.do?freeText=" />
<add key="recno" value="30" />
</appSettings>
</configuration>
Dim serverDetails As String = ConfigurationManager.AppSettings("servername")
Dim NoToReturn As String = ConfigurationManager.AppSettings("recno")

There shouldn't be a "/" in the first <configuration>
|
|

|
|
Sorry this was a typo. There is no "/" in the first configuration
