Please use profiling tools any of following tools :
CLR Profiler[^]
NDepends[^]
By using above tools, you will come to know expensive part of code. Then you can try to optimize that code.

But how can i know in which module is generating that problem.and I m using on error resume next for error resloving.

Thats what the profiling tools show you.

Nothing to do with profiling, but it could mean you are not freeing up resources if you get an error.

 Have you tried to use any of mentioned tool. Better to try out, You will granular report on which function or module is taking most of CPU time.

Comment out your error handlers. It appears that your code is generating errors in a loop, but your "error handling" code is burying the errors so you can't see them.

That's not "error resolving", that's burying the errors. If you're using "On Error..." in VB.NET code, you're digging yourself a hole. That only exists for VB6 backwards compatiblity. I highly recommend re-writing the code to use Try/Catch blocks instead.

Hi Sir,
My application normally takes CPU usage 0 - 5 in administrator account but in Guest account it takes 10- to 46.
please suggest me what is the problem
mailto: anubhava.prodata@gmail.com

|

You're using VB.NET and the old VB6 error handling?? Not a good idea...
Anyway, it's impossible to tell you what the problem is because we haven't seen your code. Don't post the entire project.
What you have to do is use a code profiler to find out where the problem is. Since the app works as an admin and bogs down as a normal user, I'd say you're doing something that requires admin rights, but your error handling is written so badly, it's burying all the errors.

I have tried to copy from Sheets("S") rows meeting condition and copy those rows to a new sheet, but not able to get the code to work. Here is my code. What could I be doing wrong?
Here is the spreadsheet fields.

i12 and k12 contain dates
variable dates are being swapped out for Sheets("D").Cell("c9") based on whether the funtion computes to True for the selected row.

I have a multiline textbox control on a form. When a user focuses on the textbox I want to check and see if a certain string (user's name and todays date) are in the textbox. If not, I want to automatically add the user's name and todays date to the end of the textbox and position the curor and scroll to the bottom. I am having trouble with the scrolling/cursor positioning part. My code will scroll down, but the cursor ends up moving to where ever the user clicked in the textbox. Does anyone know of a way to ignore where they clicked so as to override where the cursor goes? Is there another event that fires that I can grab? Am I missing something obvious here?
Private Sub txtInput_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtInput.GotFocus
Dim strAutoLabel As String = gblstrUserName.Trim & " - " & Now.ToString("M/d/yy")
'If the textbox does not contain the auto label, add it
If Not txtInput.Text.Contains(strAutoLabel) Then
If txtInput.Text.Trim.Length <> 0 Then txtInput.Text &= vbCrLf & vbCrLf
txtInput.Text &= strAutoLabel & vbCrLf
txtInput.SelectionStart = txtInput.Text.Length - 1
txtInput.ScrollToCaret()
End If
End Sub
I'd appreciate any help or advice you can give me.

In the mouse click event for the tetbox you could try:
if not (Me.txtNvs.SelectionStart = txtInput.text.length -1) then <br />
Me.txtNvs.SelectionStart = txtInput.text.length -1<br />
Me.txtNvs.SelectionLength = 0<br />
end if
'it may be something similar to determine the current selected index in the if statement
good luck

Dim intMouseClickCounter As Integer = 0
Private Sub txtInput_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtInput.GotFocus
Dim strAutoLabel As String = gblstrUserName.Trim & " - " & Now.ToString("M/d/yy")
'If the textbox does not contain the auto label, add it
If Not txtInput.Text.Contains(strAutoLabel) Then
If txtInput.Text.Trim.Length <> 0 Then txtInput.Text &= vbCrLf & vbCrLf
txtInput.Text &= strAutoLabel & vbCrLf
txtInput.SelectionStart = txtInput.Text.Length
txtInput.ScrollToCaret()
'Set counter to one so the mouseclick event will scroll to the bottom
intMouseClickCounter = 0
Else
'Set counter to one so the mouse click will not scroll to the bottom
intMouseClickCounter = 1
End If
End Sub
Private Sub txtSpecialReport_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles txtInput.MouseClick
If intMouseClickCounter = 0 _
AndAlso Not (txtInput.SelectionStart = txtInput.Text.Length) Then
txtInput.SelectionStart = txtInput.Text.Length
txtInput.SelectionLength = 0
txtInput.ScrollToCaret()
End If
'Increment counter so if user clicks inside textbox after focus has already been set,
'the code to scroll to the bottom will not run again
intMouseClickCounter += 1
End Sub
Private Sub txtInput_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtInput.LostFocus
intMouseClickCounter = 0 'Reset counter
End Sub
But this solution has flaws. It doesn't work the way I'd like when a user tabs into the textbox, and it will scroll when I don't want it to if the user activates another window/program and then returns to this form and this textbox. If anyone has any further suggestions I would appreciate it.

Most likely, your ConnectionString is wrong. What does the code look like that throughs the error.

Hi,
I urgently need to get this program running. I'm trying to remotely connect to a server using WMI (which is all fine) and then run an executable as a process on the server.
I currently get the error "Public member 'string' on type 'Uinteger' not found". I think this is something to do with the InvokeMethod line, as most examples have 'null' where it has 'Nothing'. However null is not allowed in VB.NET 2005 - it suggests using system.dbnull which doesn't work either.
<br />
' Get the object on which the method will be invoked<br />
Dim processClass As New ManagementClass<br />
processClass = New ManagementClass("Win32_Process")<br />
processClass.Scope = scope<br />
' Get an input parameters object for this method<br />
Dim inParams As ManagementBaseObject = processClass.GetMethodParameters("Create")<br />
' Fill in input parameter values<br />
inParams("CommandLine") = patchcommand 'This is a string containing the command<br />
<br />
<br />
' Execute the method<br />
Try<br />
Dim outParams As ManagementBaseObject = processClass.InvokeMethod("Create", inParams, Nothing)<br />
Dim obj As Object = outParams("ReturnValue")<br />
<br />
'Check for an error<br />
If obj.ToString <> "0" Then<br />
'Error occurred<br />
End If<br />
Catch ex As Exception<br />
'This catches any other errors from trying to run the process<br />
MessageBox.Show(servername & " - Error running process - " & ex.Message & vbCrLf & ex.ToString)<br />
<br />
End Try<br />

I'd like to get it working today if possible. We're trying to roll something out urgently across a lot of servers and this way we can do it all remotely.
|
|
|
|
|
Well just so you know, take a look at this [^]thread, it explains etiquette on the boards. Posts with urgent don't typically get responses at all, nor do posts looking for source code.
