Create a HashTable and you can add all of your StopWatch objects to it. Ideally, you'd want to create a class that can track one process, complete with it's own StopWatch, and have each instance of that class watch one process. You can then add those to a HashTable to keep track of them all.

Hi
How can i maximize the printpreviewdialog during runtime.
Thanxs

The PrintPreviewDialog doesn't expose any methods to do this. You can either use it's .SetDesktopBounds() method to set the size as large as you want, or you'll have to go through Win32 API calls to find the window handle and send an appropriatly formatted window message to the form to get it to maximize itself.

Since you're form no longer has a control box in the now non-existant title bar, you don't have Minimizie, Maximize and Restore in the context menu either. But, just clicking on the icon in the TaskBar should restore the form. If not, the solution to restoring the context menu on the TaskBar is surprisingly easy.
Handle the form's Resize event. In that handler, check to see what the WindowState of the form is. If it's Minimized, set the FormBorderStyle to anything but None, otherwise reset it to None.
Private Sub Form1_Resize(blah, blah) Handles Me.Resize
If Me.WindowState = FormWindowState.Minimized Then
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.Sizable
Else
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
End If
End Sub
Now, there's a small problem that develops. Changing the FormBorderStyle like this also changes the size of the form. When it's restored, the form shows up smaller than before it was minimized. To get around this, set the form's MinimumSize property to the current size of the form BEFORE the form is minimized by your code:
Private Sub Button1_Click(blah, blah) Handles Button1.Click
Me.MinimumSize = Me.Size
Me.WindowState = FormWindowState.Minimized
End Sub

You can not update part of a text file. You have to rewrite the entire file.

Hi
I've created a app for monitoring Internet access on workstations. I've created the project so that the main form's visible = false, when it detects the iexplore process it sets the visible = true and prompts the user for a session password. The problem is that my apps process is running in the Task Manager and the user can stop it from there. Thus dissabling my app.
 
I want to create a service that runs in the background and then starts my app to prompt user for session password. Is this possible and how can I implement it. Should I create a seperate windows service that starts my app or should I incorporate the service into my app.

After you delete the file, call the Refresh method on the FileListBox:
FileListBox.Refresh()

Hi Members,
I'm stuck in a project where I need to connect a scanner to a program(VB.net),i.e., on click of a button the scanner should start functioning.
How can I achieve that?
Regards,
Member.

TWAIN. I think there's a .NET TWAIN driver here on CP, just search for it. Either way, you need a TWAIN implimentation to talk to scanners.

Sounds like you need to look into either .NET or COM interop with Office. IT depends on what versions you want to support, the COM ones are always there, the .NET ones I'm not sure when they came out. Creating PDF, there's a couple of projects on source forge that do it, and plenty of commercial options.

How is it possible to retrieve the WMI property description field with VB 2005 / .net?
Example: for the value
<br />
root\CIMV2:Win32_PerfRawData_SMTPSVC_SMTPServer\MessageBytesTotal<br />
the Property Description is
"The total number of bytes sent and received in messages."
With this code I can get the value of "MessageBytesTotal", however how to get the description into a string variable? 
<br />
Dim mc As ManagementClass<br />
Dim menge As ManagementObjectCollection<br />
Dim mo As ManagementObject<br />
Dim strTmp As String<br />
<br />
Try<br />
mc = New ManagementClass("\\MeinServer\root\cimv2:Win32_PerfRawData_SMTPSVC_SMTPServer")<br />
<br />
menge = mc.GetInstances()<br />
<br />
For Each mo In menge<br />
strTmp = mo("MessageBytesTotal")<br />
Next<br />
mc.Dispose()<br />
Return strTmp<br />
Catch ex1 As Exception<br />
console.writeline (ex1.Message)<br />
End Try<br />
Which code do I need to add to get success?
I have tried this here, but it does not work:
<br />
strTmp2 = mo("Description")<br />
Thanks for any hint and feedback!

AFAIK, there is no way to retrieve the property/method/event descriptions in WMI. You can retrieve the list of properties/methods, and their data types, but not the descriptions.
The only place I know to get that information is in the MOF files that were used to compile the WBEM classes. It would involving parsing those file to get the info. I don't know of an API to do it for you.
I could be wrong though...

If you are realy into a bit of work, you could generate your own managed class using mgmtclassgen.exe and just add your own custom property for it.
Read on... for instructions:
The following command generates a managed class from Win32_PerfRawData_SMTPSVC_SMTPServer
mgmtclassgen.exe Win32_PerfRawData_SMTPSVC_SMTPServer /n root\cimv2 /l VB /p c:\SMTPServer.vb
The tool writes the managed class to the source file at c:\SMTPServer.vb, using the ROOT.CIMV2.Win32 namespace.
Add the file to your project.
Add the following to SMTPServer.vb somewhere near "Public ReadOnly Property MessageBytesTotal()" (about line # 2509 in my file.):
<Browsable(True), _
DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden), _
Description("Description of MessageBytesTotal.")> _
Public ReadOnly Property MessageBytesTotalDescription() As String
Get
Return "The total number of bytes sent and received in messages."
End Get
End Property
And/Or whatever you want the property(s) to be..
And/Or Your own overloads ect..
Have fun..

Hi,
Does anyone know how to send a pdf file to a printer without using Acrobat.
|
|
|
|
|
Without some component to load, parse and render the document, you can't send a PDF to the printer. It'll just print tons a garbage.
TallComponents[^] has a couple of things that might work for you.

Without seeing the code that's generating this error, it's impossible to tell you what you did wrong. Though, I get the feeling that you're trying to use a DataReader object for something it's not designed for.
