Hi,
I have a data reader populated with rows from my SQL SELECT statement.
I am looping through the coloums to write it to a XML file. But I need the name of the column for the name of the element. This is how I am looping through it and writitng it. It's only a section of my code:
With writer
' Loop through the fields
For i = 0 To dr.FieldCount
.WriteElementString("[ column name ]", dr.Item(i))
Next
End With
Please can someone help?
Regards
ma se

I hust changed the start of the loop to:
For i = 0 To dr.FieldCount - 1

Why are you writing this out to an XML file yourself? The DataSet and DataTable classes already do this for you, using their WriteXml methods.

Define "message". Are you thinking of writing both the client and server applications? Is this a chat application? Are you interacting with another application that you did or didn't write? More information is needed to answer this question.

Hi Dave
Thank for ur reply
Actualy i wanted to create desktop application where administrator can view his department employees work status, if he found anybody is taking long time then he can communicate to that employee through application.
Only Administrator and employee can communicate through application .
Hope this will clear ur doubt

This is no different than any other chat application. You just have to add a little bit of security.
The way you describe it, it's just another tool for a bad manager to become worse by micro-managing.

Hi,
Am handling the text in textbox for the below code, it works fine, I like to handle the text presents in the word document or a string value for the below code instead of Textbox1.Handle, is there any way to pass the string value as IntPtr.
Private Sub Button48_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button48.Click<br />
messge(Textbox1.Handle)<br />
End Sub
Private Sub messge(ByVal value As IntPtr)<br />
' <br />
'<br />
'<br />
End Sub
Kindly suggest me
Thanks,
Nanda

Are you passing this String to another application or inside your own? Passing by IntPtr is hardly efficient, so I don't see why you would do this. What's the point?

Hi Dave,
This is the code given in SDK,
SSCEVB_CheckCtrlDlg(Me.Handle, TextBox1.Handle, False)
Function SSCEVB_CheckCtrlDlg(ByVal parent As IntPtr, ByVal ctrlWin As IntPtr, _<br />
ByVal selTextOnly As Short) As Short<br />
<br />
<br />
End Function
Here I would like to pass the Msword Document as IntPtr instead of TextBox1.Handle as below but it doesnt support.
Dim docPointer As IntPtr = Runtime.InteropServices.Marshal.GetIUnknownForObject(Word.Application)<br />
SSCEVB_CheckCtrlDlg(Me.Handle, docPointer, False)
Kindly Suggest Me
Thanks,
Nanda

Man, you fired that question off three times in three different forums. And you missed putting it in the obvious one - the SQL Forum.

A web site and a database server are two differnt things, having your site live doesn't mean your database can be connected to, via the web ( thank goodness ). The logical thing to do here is to write a web service, which has methods to access the DB, and one to return a user count, if you want it.

I don't understand what you mean, can you clearify my question?

I can clarify my answer - having a web site that is live, doesn't in any way expose any database that may be in use on that web site. You need a web service to do that, with methods that call the database.

Hi guys.
My company just bought and installed Share Point. I hope someone has/had experience with Share Point and can point me to the right direction. I just need some guidance for development.
As a .NET developer I need to know how do I create and integrate my applications (we have bunch of them (that I built) which are used by different departments within the company. For example: We will use Share Point as Intranet (calendars, documents, project flows, etc) so how do I create and integrate custom made application into Share Point Intranet? I have never used Share Point but heard some things about it (easy to use, great value, etc.) so please understand my confusion and forgive me if I ask stupid questions?
Any books, links, examples will be greatly appreciated.
Thanks a lot.

Hi,
I'm using the invoke method on some reflection, and don't really understand what I'm passing into the function.
My function passes an object reference which needs to be passed down into the reflected assembly.
The assembly then creates an object and then passes a reference back to this newly created object through the passed in object "ConfigObj"
<br />
Public Sub ShowConfig(ByRef ConfigObj As Object)<br />
<br />
' ShowConfig() function inside my plugin takes in 1 argument, <br />
' the reference to an (config) 'object'<br />
<br />
' Create args array for the invoke() function, <br />
' containing our reference<br />
Dim args = New Object() {ConfigObj}<br />
<br />
' display the Config window <br />
' wait for it to close <br />
pShowConfig.Invoke(tsInterfaceObj, args)<br />
<br />
' all done. ConfigObj now points to something interesting<br />
<br />
' actually we're not, args(0) contains the object <br />
' we want, not ConfigObj. Therefore make sure<br />
' ConfigObj is the correct reference is given back<br />
ConfigObj = args(0)<br />
<br />
' Mmm, this now works!<br />
<br />
End Sub<br />
I *thought* that if I set args to contain my passed in ConfigObj object, when passing that down into the pShowConfig methodinfo, it would return insided the ConfigObj object passed down (inside the args() array)
BUT
I'm finding that after the .Invoke() method, ConfigObj still references Nothing, but args(0) references the object which is being passed back. Therefore I'm needing to copy the args(0) reference into my ConfigObj variable.
It looks like when I perform the args = {} line, it just create a completely new object, with objects in the array OF TYPES of ConfigObj (Object Type), and not a reference to my ConfigObj Object passed in.
Is this correct?
It doesn't "feel" right....?
any points on this?
This is fundamental stuff, which I'm not getting 
Thanks for your help,
Phil.

Not at all. It creates an array of references to Object with the size of one, and populates it with a reference to ConfigObj.
The method that you are calling is simply not populating the object that you are passing in, it creates a new object and returns it.
