There are probably more elegant ways of doing it, but one way that has worked for me is to create an example document in Word, save it as an xml file, and open the xml file with .net studio.
After that you can simply manipulate the xml file any which way you like, with your code, and finally save it programmatically as a Word doc.
My advice is free, and you may get what you paid for.

Hi,
I need some help in transmitting video data. I am using Visual Basic.NET
All the codes i have been seeing are in C, C++, or C#. Can somebody help me with thesame code in VB.NET
Thanks.

All the code you see will use DirectX. The C# code in particular is trivial to use from your app in a dll, and should not be hard to convert, either manually ( thus teaching you how it's done in VB ), or with an online or downloadable converter.

Hi, in vb6 if i want to delete a single line of code where the cursor is located, I need to press Ctrl+Y. So I have a question how could I do that in VB2005. Thank in advance.

if u move your mose to the left towards the line numbers, the pointer will change direction just before reaching the line numbers, clicking when the pointer is like this will select a whole line and can be used to select multiple, then you simply press delete. However, there may be a vb.net equivalent for what you are saying and perhaps google ca help you there.

I'm using VB.NET 2005. And I'm creating DataGridView of items one row each, you can create, edit or delete them, but I can only delete the item under the circumstance that no one has this item. What I want on the code is that the row can't be deleted if the code finds out someone has the item. The problem is that I can't stop the deletion of the row. How do I code to allow deleting a row or not?
Please offer any advice. Thank You Very Much

You how is your code supposed to know this?? What qualifies as "someone has this item"?? What item?? How is the status of who owns this item maintained?? Without knowing the answers to these questions, it's impossible to tell you anything useful.

You probably shouldn't try to stop the user from deleting the row, but simply fake it, by checking that "no one else has the item", when the user deletes the row and then call YourDataSet.RejectChanges(), if someone does. In your code it will happen so fast that to the user it looks like he didn't delete the row.
Good luck,
Johan

How to make a button default-button on a dialogbox????
(Jameel)
|
|
|
|

Set the DialogResult property to OK and set the property of the form ( I think it's OKButton or AcceptButton ) to be that button. One causes the dialog result to be set when the button is clicked, the other causes the button to be clicked when you press enter.

Yeah, that's about the slowest way to do it. A better method would be to add each button to a hashtable, or some other key/value pair collection and use the Key you get as the key to get at the button (value) in the collection. No for/next loop required.

Isnt it a collection
"dim button as myButton= mykeyboard.controls(key.tostring)"
actually "myKeyboard" is a user control and is made of user control "myButton"... cant i directly point a button with in the keyboard????
plzz explain what collection i can use and how. i m

I already did!! A HashTable!
Dim buttonsCollection As New HashTable()
buttonsCollection.Add(Keys.A, MyAKeyButton)
When you want to get at that button when the suer presses the A key:
Dim b As Button = buttonsCollection(Keys.A)
or something like that. It's written off the top of my head, so it could be a little wrong...

Use a radio button list, then you can set it's datasource to bind to a list from your database.

I am using VB.NET 2003, MYSQL database and Crystal Reports. I am able to generate 1 set of reports using the following code:
Imports MySql.Data.MySqlClient
Imports SeungNiMartialArtsDB.modFunctions
Public Class frmRptProgramAttendance
Inherits System.Windows.Forms.Form
Private m_Conn As String
Private m_Program As String
Private m_ReportType As String
Public WriteOnly Property ConnectionString() As String
Set(ByVal Value As String)
m_Conn = Value
End Set
End Property
Public WriteOnly Property Program() As String
Set(ByVal Value As String)
m_Program = Value
End Set
End Property
Public WriteOnly Property ReportType() As String
Set(ByVal Value As String)
m_ReportType = Value
End Set
End Property
Private Sub cryRptView_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cryRptView.Load
Dim conn As New MySqlConnection
Dim myCommand As New MySqlCommand
Dim myAdapter As New MySqlDataAdapter
Dim sql As String
conn.ConnectionString = m_Conn
myCommand.Connection = conn
Select Case m_ReportType
Case "Roster"
sql = "select * from tblviewattendance WHERE program_name='" & m_Program & "' ORDER BY lname;"
Case "Attendance"
sql = "select * from tblviewattendance WHERE program_name='" & m_Program & "' AND last_class_attend=" & DateToLong(Now().ToLongDateString) & " ORDER BY lname;"
End Select
myCommand = conn.CreateCommand
myCommand.CommandText = sql
myAdapter = New MySqlDataAdapter
myAdapter.SelectCommand = myCommand
Dim progDS As DSProgram_Attendance = New DSProgram_Attendance
progDS.Clear()
myAdapter.Fill(progDS, "tblviewattendence")
Dim myReport As New rptProgramAttendence
myReport.SetDataSource(progDS)
cryRptView.ReportSource = myReport
conn.Close()
conn.Dispose()
End Sub
However, if I use the same set of code, but change the Datasets, and the SQL statements, the report does not generate. It leaves me with the following error:
"An unhandled exception of type 'System.NullreferenceException' occured in mysql.data.dll.
Additional information: Object reference not set to an instance of an object.
Below is the code that is generating the error: Please help!!!!!
Private Sub myViewer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles myViewer.Load
Dim conn As New MySqlConnection
Dim myCommand As New MySqlCommand
Dim myAdapter As New MySqlDataAdapter
Dim sql As String
conn.ConnectionString = m_Conn
myCommand.Connection = conn
sql = "SELECT fname, lname, birthdate FROM tblmembers;"
myCommand = conn.CreateCommand
myCommand.CommandText = sql
myAdapter = New MySqlDataAdapter
myAdapter.SelectCommand = myCommand
Dim birthDS As DSbirthdays = New DSbirthdays
birthDS.Clear()
myAdapter.Fill(birthDS, "tblviewattendence")
Dim myReport As New rptProgramAttendence
myReport.SetDataSource(birthDS)
myViewer.ReportSource = myReport
conn.Close()
conn.Dispose()
End Sub

I have a series of forms which have textboxes that require data to be entered over the page.
1/ How do I make it so that the cursor jumps to the next textbox (in the order I program) when the "enter" button is hit, regardless of whether or not any data has been entered?
2/ Can I set a key to reverse up in the same manner? eg. the left arrow key.
Sorry if this is a simple one, but I have been searching and not finding much helpful info.
Thanks F
