Dim myParameterFieldDefinition As ParameterFieldDefinition = myParameterFieldDefinitions(PARAMETER_FIELD_NAME)

Please check the property ParameterFieldName.
You may have to loop through all items in ParameterFieldDefinitions and check the value of ParameterFieldName. What are the values for this field?

i am getting some trouble with a tutorial that i found on msdn web site : http://msdn.microsoft.com/en-us/library/ms227722.aspx.
i would like to pass a parameter to my CrystalReport document,but i would like to send an integer value to my CR document and just one value(because in the tut its sending and array of string values).
the code is the fellowing
Private Const PARAMETER_FIELD_NAME As String = "numb"
Private impbonrecepReport As ReportDocument
Private Sub ConfigureCrystalReports()
Dim myArrayList As ArrayList = New ArrayList()
myArrayList.Add(999)
Dim numbrecep As Integer
numbrecep = 999
SetCurrentValuesForParameterField(impbonrecepReport, myArrayList)
impbonrecepReport = New ReportDocument()
Dim reportPath As String = Application.StartupPath & "\" & "ImpBonReception.rpt"
impbonrecepReport.Load(reportPath)
CrystalReportViewer1.ReportSource = impbonrecepReport
End Sub
Private Sub SetCurrentValuesForParameterField(ByVal myReportDocument As ReportDocument, ByVal myArrayList As ArrayList)
Dim currentParameterValues As ParameterValues = New ParameterValues()
For Each submittedValue As Object In myArrayList
<big>Dim myParameterDiscreteValue As ParameterDiscreteValue = New ParameterDiscreteValue()</big>
myParameterDiscreteValue.Value = myArrayList.ToString()
currentParameterValues.Add(myParameterDiscreteValue)
Next
Dim myParameterFieldDefinitions As ParameterFieldDefinitions = myReportDocument.DataDefinition.ParameterFields
Dim myParameterFieldDefinition As ParameterFieldDefinition = myParameterFieldDefinitions(PARAMETER_FIELD_NAME)
myParameterFieldDefinition.ApplyCurrentValues(currentParameterValues)
End Sub
i got this error message
An unhandled exception of type 'System.NullReferenceException' occurred in GestionStock.exe
Additional information: La référence d'objet n'est pas définie à une instance d'un objet.
in this line
Dim myParameterFieldDefinitions As ParameterFieldDefinitions = myReportDocument.DataDefinition.ParameterFields<br />
can you help me to solve this problem? thank you

The error is telling you that the object isn't initialized. And it is right.
Change your code to the following:
impbonrecepReport = New ReportDocument()
Dim reportPath As String = Application.StartupPath & "\" & "ImpBonReception.rpt"
impbonrecepReport.Load(reportPath)
SetCurrentValuesForParameterField(impbonrecepReport, myArrayList)
CrystalReportViewer1.ReportSource = impbonrecepReport
Initialize and load your report first, then set the parameter value's and then show it.
You'll also have to change
ByVal myReportDocument As ReportDocument
to
ByRef myReportDocument As ReportDocument
Or make the sub into a function and return the report at the end.
Basicly you passed an empty object to the 'SetCurrentValuesForParameterField'.

I have an MDI application. In it, I have a panel docked to the top as a 'header' and a flowlayoutpanel docked to the right for a menu. This leaves everything else to be the MDI container for children forms. Everything works well here, and while polishing off the application I decided to set a background image for the MDI container.
Great, looks great.
There is a button which will shrink the menu to expand the MDI container area, but for some reason, despite my background image being set to stretch, it is never repainted and I get a very awkward background. This applies for when you stretch the MDI container by using the horizontal and vertical scroll bars.
Anyone know how I can force the background to be repainted when my application is resized or controls are hidden / expanded to 'grow' the MDI container?
If requested, images will follow to demonstrate behavior.

From Your MDI-Form LOAD()
Dim Img As Image = Image.FromFile("C:\Eliotta\For_icons\Saudi_Sea.jpg")
Me.Controls(Me.Controls.Count - 1).BackColor = Color.LavenderBlush
Me.Controls(Me.Controls.Count - 1).BackgroundImageLayout = ImageLayout.Stretch
Me.Controls(Me.Controls.Count - 1).BackgroundImage = ResizeImage(Img, Me.Width, Me.Height)
end sub
Private Function ResizeImage(ByVal Img As Image, ByVal Width As Integer, ByVal Height As Integer) As Image
Return New Bitmap(Img, Width, Height)
End Function

Hi,
The Microsoft.Win32 namespace has a SystemEvents class containing a SessionEnding event. The associated SessionEndingEventArgs has a Reason property which can have a value of Logoff or SystemShutdown. I think that's what you need.

Log in through FTP and get the directories or files available, if it is a webserver and you're trying to get the contents of that directory, typically if there is no index file it will show you a list of files and directories available. If there is an index file, as far as I know you're out of luck.

Thanks for your reply.
Yes it is a webserver and I am trying to get the contents of that directory but I don't know what exactly to do so.
Can you explain with some piece of code??
Thanks.

My problem is that i want to know the web sites open in my network's pc
so that i could monitor all the web site open on that computer.
i want to develop a desktop application that will be install on each machine and will keep the url information and at particular time it will send an email containing all the requested URLs.
Please help and guide me.
|
|
|
|

Surely all this information is already available to the network administrator in various logs.
This has more than a wiff of malicious software  .

Either that or 1984 might be good reading for him. 
My advice is free, and you may get what you paid for.

I think he either uses it to put himself to sleep or thinks we are complete idiots. No doubt someone will point him to an article that will allow him to do this.
|
|
|
|
|
Actually there is a client, he wants to monitor all the web request, he don't wants to go on particular machine but he wants to receive an email containing that URI/URLs. it is totally new task for me and i thought that code project family member can do everything that's why i need your help.
so tell me is it possible by vb.net programming or not.
Thanks
