Hi,
I have just acquired a dual processer (SMP) machine for my latest database project (SQL Server & vb.net). It is working great. But when i check performance graph in my Windows Task Manager, it shows only one processor working to almost 100% and second processor pitching in only for short while befor going idle.
How do i develop my vb.net application that utilizes maximum of both the processor, like SQL Server itself and some graphics application like Ulead products while rendering graphics.
Note: I have tried to set the Affinity and Task priorities in Windows Task manager ... but with no success.
I assume it is some base architecture that utilizes multi-Processors, that i am lacking.
Any help would be much appreciated.
Regards,
msali.

Is your app written to use multi-threading?
Using a second processor doesn't happen automatically. You actually have to write your app to use mutiple threads of execution. Otherwise, you're running a single threaded app that only runs on a single processor.

Dear all,
I have a problem on how to get the PnP ID of a USB Thumbdrive. I will get the driveletter of the
thumbdrive, say "J" but not able to assoiciate the PnP ID of the USB device in that particular drive (ie J), instead the code given below is giving PnP ID of all the mounted thumbdrives
I will be very thankful if someone can get me the solution
code:
Dim obj, objs, buf
Set objs = GetObject("winmgmts:").InstancesOf("Win32_DiskDrive")
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set colDrives = objFSO.Drives
Dim drv As String
drv = "J"
For Each obj In objs
For Each objDrive In colDrives
buf = IIf((obj.InterfaceType = "USB") And (objDrive.DriveLetter = "J"), _ obj.PNPDeviceID, "")
buf = "Model: " & obj.Model & vbCrLf
buf = buf & "PnP Device ID: " & obj.PNPDeviceID & vbCrLf
msgbox buf
Next
Next
End Sub
thank you

You might want to do some research on this by reading and studying the code in this[^] article on MSDN.

Hello..
Can anybody tell me how to give readonly access to some of the rows in datagrid while leaving others as non-readonly. I have binded a dataset with the datagrid.
Plz reply urgently
Take care
|
|

|

The idea is....
When the cell gets focus... depending on the conditions (in your case - rowNum) you can set the datarow column's ReadOnly property accordingly
<br />
Private Sub dg_RowChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)<br />
Try<br />
Me.Cursor = System.Windows.Forms.Cursors.WaitCursor<br />
idCol.ReadOnly = True<br />
If "condition" Then<br />
idCol.ReadOnly = False<br />
End If<br />
Catch ex As Exception<br />
MessageHandler.HandleError(ex)<br />
Finally<br />
Me.Cursor = System.Windows.Forms.Cursors.Default<br />
End Try<br />
End Sub<br />
P.S. idCol - will be a column which will be made readOnly in this case

Hello. I have a homework assignment where we have a status bar which value comes from a percentage of "done" work. Don't worry, you're not doing the assignment for me. Already got the formula set up and it works, but would like to have a percentage along with the progress bar's value. This isn't part of the assignment, but I would like to add it to make a little more professional. I noticed there is a property .text. No text actually shows up. Is this possible?
|

Hello!
To show the current value of progress bar you can use the property VALUE of progress bar like,
Var=ProgressBar1.Value
Now you can add up a Timer and on each timer tick, update the status bar with the variable 'Var'.

Is it possible to have text show up in the progress bar?
Thanks for the reply!

Not with the intrinsic Progress Bar control.
You can create your own progress bar that you fill in and draw the text using your own painting algorithm.
This was easy in VB6, in VB.NET, not so much. 
|
|
|
|
|
I'm a newbie, how would I go about creating my own?
|
|
|
|
|
You'll have to creat your own ProgressBar class, inheriting from ProgressBar. Then you'll override the OnPaint event and draw the progressbar and text yourself.
But, if you go through this, consider that you might go too far and your prof will suspect you didn't write the code. Have you even come close to covering inheriting from other classes? Have you covered overrides? Have you covered drawing your own controls?
Yeah, this stuff might get you extra credit, but it's a bunch of work for a little credit.
I only say this, because in a class I took, I got accused of not writing the code myself. It turned into a huge mess with accusations of plagerism. I was able to wiggle my way out of it by having the prof give me a different assignment and I wrote it right in front of him.

Ok, not just wanting to do it for extra points. It would be nice if I could get it done in time to do so. It's actually an application I could use in everyday stuff and would like to have it for that too. But I'll give it the good old try and if I don't get it, oh well. Thanks!

Hmm....
I cant find any property of progress bar to display text...
but you can place the progress bar in a separate form and place a label on top of it and update the label text on timer tick with the desired text...
Remember you should explicitly update the text...

How to send and recive file with winsocket???
I try end get error the socket is not open or connection not established!!!
But HOST and Clien are connected...!
|
|
|
|

Without seeing any of your code, it's impossible to tell you what you'r doing wrong. The description you've given is too vague to be of any use in troubleshooting your problem.
How are you trying to transfer this file? How is this connection being made? What does the client code for this look like? The server code?
