Re: How can I show a form while I read records from db?

Hi Dave!

I am loding the words from different dictionery. I had decided not use of a seperate thread for this purpose because I thought it would be possible to show form first and then load the database but it didn't work out that way. I think you are right I better consider in using a seperate thread.

Thanks a lot. Smile | :)

WMI, Win32_Process or Process class question with IE

just wondering if there's any way I can get the currectly active URL of IE using the process class or WMI?...

Basically I want to be able to remotely shut down IE if a certain webpage is hit.

I can get PID and name easily with the process class to put them in a datagrid, and then kill the process with WMI, just wondering how much more is possible.

No, you can't get it using WMI. You have to do this using the Shell.Application object. You can then get the open browser windows from the Windows property, then iterate through those to get the LocationName and LocationURL's.

You'll need code running on each of the client machines you're monitoring because I don't think you can create the Shell.Application object on a remote server.

The other problem is that this will only work for IE browser windows. It will NOT work if the user is using any other web browser.

Rats... was hoping to get away without having anything running on every machine... idea was to just have an old system sitting in my server room keeping an eye on things when required... I suppose it would be perfectly feasable for me to just have the client side bit of code as a very small app that can be run as a process (it won't have a GUI) when required on each client machine.

programs already doing its main job which is killing MSN on certain computers when people take advantage of my relaxed nature so I don't have to block it for everyone. I could set up the firewall to block certain sites like myspace.com but again, I don't want to kill it for everyone, only the people who are abusing it, and as I'm using IPCop its a bit of a pain to turn it on and off.

You can't call functions in a Java JAR file alone. It uses an entirely different runtime than the .NET CLR. The Java classes you want to use have to be exposed through COM in order for you to use them. If they're not already, and you don't have to source, your not going to be able to use that JAR file without writing your own Java code wrapper around those classes and exposing them to COM.

I don't do any Java development, so I don't even know if it's possible to expose that stuff through COM...

serialzable XmlNode

Im trying to serialize this class (as shown below) but im getting an error
"The type System.Xml.XmlNode is not marked as serialzable". How do i solve this problem?

<serializable()> _

Private mNotificationServer As String
Private mNewHour As Xml.XmlNode

Imports System.Xml.Serialization

<XmlRoot("Testing")> _
Public Class clsTest

    Private strName As String

    <XmlElement("NameToBeReturnedInXML")> _
    Public Property Name() As String
        Get
            Return strName
        End Get
        Set(ByVal value As String)
            strName = value
        End Set
    End Property

End Class

This is the type of setup if you are wanting to create a strongly typed object that is serialized. The XmlRoot attribute will be the main wrapper around the entire stream. The XmlElement attribute will be each element obviously.

This can get pretty ugly but it is very useful. If you wanted to have multiple employers for a person you could create an Employer class with all the information you want along with the Xml tags. Then you would create the main class and setup an array of type Employer(). You would then create the array of the object (there are other ways, this is how Ive done it) and add that array of Employers to the main class. Then when it is serialized it will do something like the following. (Note I had to remove the < >'s in order for it to show)

UserInformation
      Employers
          Employer
               EmployerName Emp1 /EmployerName
          /Employer
          Employer
               EmployerName Emp2 /EmployerName
          /Employer
     /Employers
/UserInformation

You can do this by adding the value to one XML file and reading the XML file to dataset and set reportsource as this dataset.

To do this I prefer to store the heading too in XML file. When creating XML file , check the value is null. If so make heading also null. Then in reports also heading won't come

Debugging: cannot drill down into object collections in QuickWatch window

My colleague and I have recently upgraded our projects from .NET Framework 1.0 and VS2002 to .NET Framework 2.0 and VS2005. We also applied the latest VS2005 service pack.

Our problem: normally when debugging we use the QuickWatch window to drill down into and view collections of objects belonging to the parent object we are "watching". THIS NO LONGER WORKS...instead, we get a message in the value line against the object collection saying:

"In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user."

This is incredibly frustrating, particularly when we have large nested collections of objects.

We are pretty sure this feature was working fine after we upgraded, but we are not so sure that it was working after we applied the VS2005 service pack.

Can anyone suggest any ideas that might help to solve this issue, as it is a massive hinderance to our productivity and our office swear box has been raking it in!!!

Cheers

Are you debugging a windows forms project, or a web project? Because if you are in a web project, just setting the build to debug mode isn't enough for VS2005. You would need to manually edit the web config to say debug=true instead of debug=false to get the debugger to work.

Otherwise, could you be a little more specific as to what you are quickwatching? Maybe give us the actual code you quickwatch?

Hope this helps.

prevents it from being opened or locked."

How to solve this error? please help!

My following code as below:

Try
DB = New OleDbConnection("Provider=microsoft.jet.oledb.4.0; data source=C:\prdsystem\prdnsf.mdb")
DB.Open()

I am using
the following code from VB.NET( I put only necessary lines to be short)
AcroApp = CreateObject("AcroExch.App")
PDDoc = CreateObject("AcroExch.PDDoc")
InsertPDDoc = CreateObject "AcroExch.PDDoc")
PDDoc.Create()
InsertPDDoc.Open(OutPdfPath)
.....
If PDDoc.InsertPages(-1, InsertPDDoc, 0, iNumberOfPagesToInsert, 1) = False Then
MsgBox("Error Inserting Pages ")
Exit For
End If
And this InsertPages(...) work fine for
some documents(that was opened before upon
name InsertPDDoc). But some pdf files the client sent to us are not working.It is
totally depends on pdf file that was opened.

Could you please answer why it is different on different files? The same code could do InsertPages() for one pdf file and could not do for another.
What 'wrong' with that file where it could not do it. I would appreciate any
clue on this.
Thank you.
