Set a timer to start your screensaver. reset it every time your app recieves a keyboard or mouse event.

this is an example of out I set a textbox:
Private Function InputBoxValue(ByVal controlname As String, ByVal value As String)
Dim tmpIBox As mshtml.IHTMLInputTextElement = doc.getElementsByName(controlname).item(, 0) 'get first name inputbox
tmpIBox.value = value
End Function
But I can't for the life of me figure out how to set a radio value... example:
<INPUT NAME='DL_trial_timeAmPm' TYPE=radio VALUE='AM' >AM<INPUT NAME='DL_trial_timeAmPm' TYPE=radio VALUE='PM' >PM<P> 
Thanks in advance.

I need to set a radio value on a webpage....... I programmatically login into the website using the axwebbrowser control. Then from there on I use getElementsByName Method on the document to get the fields value or set it. I can get the method to work for every other field type except radio option which is an input field. If you've never worked with html and this object you'll of course have no idea what I'm talking about. Again thanks in advance if you have any help in this matter.
example that I'm trying to perform:
Private Function InputRadioValue(ByVal controlname As String, ByVal value As String)
Dim tmpIBox As mshtml.IHTMLOptionButtonElement = doc.getElementsByName(controlname).item(, 0) tmpIBox.checked = True
End Function
I've changed the index on the item but it doesnt seem to point to the right value

Try this...
Dim tmpIBox As mshtml.IHTMLInputTextElement = doc.all.item(controlname, 0)

I receieved the following error when I used the code on the previous thread. "QueryInterface for interface mshtml.IHTMLInputTextElement failed" Now the code that I used before was:
Dim tmpIBox As mshtml.IHTMLOptionButtonElement = doc.getElementsByName(controlname).item(, 0) 'get first name inputbox
tmpIBox.checked = True
now this code worked for the first option value but there are two with the same name like so:
AMPM
so basically I need to get the second option now when i try to change the index.. it doesn't work. any suggestions?

Hi all
I have the following piece of code where I am checking for the status of the printer. But I am not able to figure out why even while the printer is priting Printer.PrinterStatus returns 2 which corresponds to Unknown printer status
Please let me know if the code is wrong and is there any other way to check for the status of the printer.
Code is
Private Sub btnPrinter_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrinter.Click
Dim PrinterSet As Object
Dim Printer As Object
Dim DefaultPrinter As Object
PrinterSet = GetObject("winmgmts://localhost")
DefaultPrinter = PrinterSet.ExecQuery("Select * from Win32_Printer Where Default = True")
For Each Printer In DefaultPrinter
MsgBox(Printer.Name & ": " & Printer.PrinterStatus)
Next Printer
End Sub
Thanks and Regards

I put the code under timer event of very small duration and it worked fine.
But I dont get any other states than IDLE,UNKNOWN,PRINTING.
How to retrieve the printer state like warmingup,paper jam,toner low etc
If anyone has idea about it please let me know
Thanks and Regards

You can't get that information because it's not exposed to the WMI methods your using. You can only the same information you see if you open the Printers folder to see the details of all the printers installed on the system.

So can I get the required information if I use System.Management.ManagementObject class ?

You can't get it if the underlying provider doesn't supply that kind of status information to WMI. You'll have to use other methods to get more granular status information. This may include P/Invoking the Win32 API GetPrinter function, communicating with its driver using DeviceIo, or getting the information directly from the printer depending on how it's connected to the machine and if it supports such methods.

Hello...
I'm new to network programming and am trying to create a simple application that will allow me to send test TCP messages to a listening windows service. Here is my send function:
<br />
Function Send(ByVal message As String) As String<br />
Dim stream As NetworkStream = Nothing<br />
Dim responseData As String = ""<br />
Dim localEP As New IPEndPoint(IPAddress.Parse("127.0.0.1"), 11000)<br />
<br />
Try<br />
<br />
' Instantiate a TcpClient with the target server and port number<br />
Dim client As New TcpClient(localEP)<br />
<br />
' Convert the data to send into a byte array<br />
Dim data As Byte() = System.Text.Encoding.ASCII.GetBytes(message)<br />
<br />
' Get the NetworkStream for the TcpClient for sending and receiving<br />
stream = client.GetStream()<br />
<br />
' Send the message to the server. <br />
stream.Write(data, 0, data.Length)<br />
<br />
' Buffer to hold data returned from the server.<br />
data = New [Byte](256) {}<br />
<br />
' Read the response from the server up to the size of the buffer.<br />
Dim bytes As Integer = stream.Read(data, 0, data.Length)<br />
<br />
' Convert the received bytes into a string<br />
responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes)<br />
<br />
Catch ex As SocketException<br />
MsgBox(ex.Message)<br />
Catch ex As IOException<br />
MsgBox(ex.Message)<br />
Finally<br />
<br />
' Make sure that the NetworkStream is closed.<br />
If stream IsNot Nothing Then<br />
stream.Close()<br />
End If<br />
<br />
End Try<br />
<br />
Return responseData<br />
End Function<br />
<br />
The line of code as follows...stream = client.GetStream() causes this InvalidOperationException:
The operation is not allowed on non-connected sockets.
I'm using VS 2005 Beta 2 (.NET 2.0). I have no idea what the problem is. Any ideas?
Thanks in advance!

You have to get connected before to do anything!!
sockSMTP.Connect(v_Remote)
Then you can do what you want. I hope it helps

Could anybody help me. Im trying to work out how to use a progress bar with the browser control so i can see how much of the page is loaded etc like in internet explorer.
If anybody has any demo programs or sample code or could explain it i would be grateful.

I found this page[^] that gives an example of how to use a progress bar in a web browser control (VB.NET). The example uses the DownLoadBegin, DownLoadComplete, and ProgressChange events of the browser control. I didn't try the code but it looks relevant...

I have two combo boxes in my datagrid.
I need to be able to select a value in one (databound) combobox and have the values in the other (on the same row) change (run a new SQL statement based on the value selected and repopulate).
Have you (the reader) done this before and/or can you point me to a resource?
Let me know if I am too cryptic.....
Thanks in advance.

I am not sure this will help you, but in cases where I have controls whose contents change based on other controls I find most suitable to use DataViews.

One of the arguments that I must pass to the Function in a DLL is a pointer to an array of a structure that has a byte array in the middle of the structure with a fixed length of 256 bytes. Here is the Structure:
<StructLayout(LayoutKind.Sequential)> _<br />
Public Structure KEYBOARDINFO <br />
Public KeyboardID As Int32<br />
Public KbdName(0 To 255) As Byte<br />
Public pKeyboard As Int32<br />
End Structure
My problem is I cannot get VB to make this structure be sequential in memory since it has the KbdName(255) in the middle of it. I have tried everything I can think of and VB always puts KbdName at the end. How can I get it to be sequential, so I can pass it to the function as an argument.

Try applying the following attribute to your structure...
<br />
< StructLayout(LayoutKind.Sequential) > _<br />
Public Structure KEYBOARDINFO <br />
Public KeyboardID As Int32<br />
Public KbdName(0 To 255) As Byte<br />
Public pKeyboard As Int32<br />
End Structure<br />
[Edit]
Oops. This website took out the attribute in the above code on my 1st post. It should show up for you now.
