There must be many ways:
1. write a small program that copies a template, renames it the way you want, then opens it
for editing.
2. write some VBA code that sits inside your template and does what you need; I trust this
is possible, but I never actually did such things.

Hello,
i want to send messages between two PCs and I have a problem with that, if i get a message from the server, i can display it in a MessageBox, but if i want to write that in a String or StringBuilder, only the first time it puts the message in the string. The other times i get a new message from the server, it shows me the message in the message box, but it doesnt put it in my string oO?
Here's the code:
//Code deleted
But there's something crazy, it shows me every time two messageBoxes if i get a message from the server, one, where the really message from the server is in, and one empty, but it isn't really empty, i checked that and i found out that the ascii code of this empty message is "0"... so is that maybe the problem? and where it could come from... i have no idea... oO
Thanks for your help

Hi, I can't see anything obviously wrong in your code, however without the server code it's a bit difficult to test. Could you post that too.

Hi softwarejaeger, it looks like the problem is in the User.Process method. Notice that the client.ReceiveBufferSize seems far to large for your message... the size is in fact an 8KB block, so you need to use the return value from Client.GetStream.Read before calling Send (just as you've done in Client.DoListen). Heres the modified code:
Dim Buffer(client.ReceiveBufferSize-1) As Byte
Dim i As Integer = Client.GetStream.Read(Buffer, 0, CInt(Client.ReceiveBufferSize))
MsgPack = System.Text.Encoding.ASCII.GetString(Buffer).ToString()
Send(System.Text.Encoding.ASCII.GetString(Buffer, 0, i))
A couple of other things: vb.net arrays are zero based and are defined by specifying the upper limit, not the array length - thats why i've added the -1 to the array dim.
Also, for all programmers sakes, please avoid using GoTo  A While loop is a much more elegant way of looping through this method.
Good luck!
Rob

Noone is going to just hand you the code.
You don't have the Windows Internal's knowledge to pull this off. It's not as simple as clicking a button and calling SendKeys. Do you think you have the skill to have a button on your form clicked successfully without your window having the input focus?? Do you know what the "input focus" is??

Hello,
I am trying to do the following:
Private Sub GetDepartmentTest()
Dim myDataset As New DataSet("Databasename")
'load data from xml file
myDataset.ReadXml("C:\XmlDatabase\Data.xml")
Dim myDataRow As DataRow = myDataset.Tables("Department").Rows(0)
' the next line gives an error
Dim myDepartment As Department= myDataRow
MsgBox(myDepartment .Name)
End Sub
Class Department
Inherits Data.DataRow
Public Sub New(ByVal builder As DataRowBuilder)
MyBase.New(builder)
End Sub
Property Name() As String
Get
Return Item("name")
End Get
Set(ByVal value As String)
Item("name") = value
End Set
End Property
End Class
But I keep getting an error:
<br />
System.InvalidCastException was unhandled<br />
Message="Unable to cast object of type 'System.Data.DataRow' to type 'Department'." <br />
The error occurs on this line:
Dim myDepartment As Department= myDataRow
Can someone tell me what I do wrong?

You are mixing you data types.
You need a property for each field in the table
You need a private var for each field
then you can populate the object
Private Overloads Sub RowToObject(ByVal oTable As DataTable)<br />
If (IsNothing(oTable) OrElse oTable.Rows.Count = 0) Then 'no table not row then empty the object<br />
mvPFClassID = Nothing<br />
mvPFClass = Nothing<br />
mvModified = Nothing<br />
mvModifiedBy = Nothing<br />
Else<br />
Dim oRow As DataRow = oTable.Rows(0)'get the first row from the table<br />
mvPFClassID = IIf(IsDBNull(oRow("PFClassID")), 0, oRow("PFClassID"))'load the properties via the private vars<br />
mvPFClass = oRow("PFClass") & ""<br />
mvModified = IIf(IsDBNull(oRow("Modified")), Nothing, oRow("Modified"))<br />
mvModifiedBy = oRow("ModifiedBy") & ""<br />
End If

Open Image file in Binary mode and send it through serial port.
and receive also in Binary mode.
put your serial port encoding to UTF-8
use this for put UTF-8 Encoding
SerialPort1.Encoding = System.Text.Encoding.GetEncoding(1252)

There is an on screen keyboard CP article. Getting it to work between apps, is probably a little complex for you right now.

In order to press a button in one application, it needs to have the input focus. Since your keyboard now has the focus, what was the last control to have the focus??? Hint: There's no function or method that will tell you that. So where do you send the key stroke??

Please help me i've seen it done before i just dont know how to code it in i think possibly you could set it so when a button is pressed it opens a microsoft word document and then all the other buttons simply Word.Application = Word.Application & button1.Text but word. Application does not seem to work in vb 2008 express edition.
Can no one help me
Please

This should be a softball for some of you.
I want to have all of the text in a textbox highlighted when I enter (click, tab, etc) into it. How do you do that?
Thanks in advance!

Use the selectionstart and selectionlength properties, set them to 0 and the length property of the text.

Create a handler for the GotFocus event & use SelectAll method. This works for tabbing between controls. Select all on click is a difficult, because the control uses mouseDown to set the caret. You could handle the MouseDown event in the same way as GotFocus & see if you like the result.

You'd have to handle the ItemChecked event of the ListView, which will give you the item that was clicked on. You'd then have to set a static flag in the event handler that will signal that you are changing check marks. Iterate over the items in the list, changing each check mark, then reset the flag. Since changing the check mark will fire the same event again, the handler code has to start by check that flag. If it's set, then the handler code can exit without making any changes.
But, wouldn't this be a job for RadioButtons?? After all, this is exactly what they do.
