When i first started VB6 i used to hard code constants into a separate Module.
Then i moved on to using an ini file instead as this allowed me to change server paths and server names
plus other info without the need for recompiling code.
Now i'm onto and new to VB.NET i want to adopt a good practise and have started using an xml file instead which i then read into the application to initialise certain system properties.
What i want to know is what other people are doing or is there a better standard that
folks are using?
Many Thanks

don't know if this exist in 2003 but in 2005 there is a tab 'settings' on the properties of you'r project
here you can give a settingname, type, scope and value
this does exactly the same as what you do with the plus side that you can access these 'settings' in code like this:
my.Settings.nameofsetting
it basacly creates a xml file wich can be opened in notepad to alter it
I always use this
If my help was helpfull let me know, if not let me know why.

Hola,
I use a package called AutoMod to make simulation models and to send messages from VB to this package teh AutoMod help says to use the next code
Call amxEvents.CallFunction("FsetMotorState", Array(1, Range("B10").Value))
However when I use this code in VB 2005 I get an error message that Array is a type and cannot be used like this.
What do I have to do in VB to get an array as the second argument?
Thanks in advance,
Nasko
See below for the syntax of the CallFunction method.
amx.CallFunction(funcName, params)
The syntax elements are defined as follows:
Syntax Element
Description
amx
An object variable that refers to the AutoMod runtime object.
CallFunction
The name of the method.
funcName
A string that indicates the name of the function in the AutoMod model that you want to call.
params
An array of variants that define the arguments required by the user-defined AutoMod function. The array must have as many values as the AutoMod function has arguments (any extra values are ignored). The variant values are automatically converted to the type of the associated argument in the AutoMod function in the model.
Note: The params syntax element is required. If the AutoMod function you are calling has no arguments, you must still define an empty array. For example:
Call amx.CallFunction("FAmodFunction", Array())
'An empty array is passed to the AutoMod function FAmodFunction
|

this is one way:
<br />
Dim a(Range("B10").Value) As Object<br />
a(0) = "mlqjf"<br />
Call amxEvents.CallFunction("FsetMotorState", a)<br />
you can replace object with string,integer,long,...
plus side of object is that you can put anything you want in it
down side the function callfunction might not know what to do with certain objects
hope this helps
If my help was helpfull let me know, if not let me know why.

Thanks,
It worked.. the only thing I had to change was the Excel cell reference and change it to 0 (for a one dimension array).
So the problem is fixed... thanks!

Hello,
I am adding a column to datagridview.
The column values are numbers or empty string depending of the records returned from my SQL.
When I am sorting the column, it is sorted like string:
123
15
20
25
...
instead of
15
20
25
123
Please help
This is a part of my code:
'add the column to the datagridview
datagridview1.Columns.Add("SCQTYMV", "Qty Moved-In")
'CellFormatting Event
Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
Try
With CType(sender, DataGridView)
If e.ColumnIndex = .Columns("SCQTYMV").Index Then
If .Rows(e.RowIndex).Cells("SCQTYMV").Value.ToString = "" Then
e.Value = ""
Else
e.Value = Cint(.Rows(e.RowIndex).Cells("SCQTYMV").Value)
End If
End If
End With
Catch ex As Exception
MessageBox.Show(ex.Message, "DataGridView1_CellFormatting", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub

Hi All,
I have a table Named Table1 and i have displayed all the records in a datagridview and after i make changes ie.Edit the Datagird i want to save the changes to the same table after i click Update Button.
Can anyone tell me how to do this updation at a time not record by record
Example of what i have done:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Vidya\Visual Studio 2005 Projects\DatasetProject\Sample.mdb"
con.Open()
cmd.Connection = con
cmd.CommandText = "Select * from Table1"
da.SelectCommand = cmd
da.Fill(pTable)
DataGridView1.DataSource = pTable
dr = pTable.NewRow()
dr("Name") = "Doe"
dr("Place") = "John"
dr("Email") = "120"
pTable.Rows.Add(dr)
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Cb As OleDb.OleDbCommandBuilder = New OleDb.OleDbCommandBuilder(da)
da.Update(pTable)
MsgBox("Updated")
con.Close()
DataGridView2.DataSource = pTable
End Sub
When i give the da.Update(pTable) or dataset
It gives me following error:
Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.
I think u have got what i am doing
Thank in advance

You create an instance of he form class and call ShowDialog on it. If you didn't know this, you really need to buy a book and work through it, if you want to get anywhere.

christian is correct
this is the first step in developing windows application..
lots of tutorials are available on net which starts from scratch..
better read them first.
nyways for this particaular problem of yours, here is the code..
in button click event of form1 code like this..
<br />
button1_click()<br />
dim a as new form2 'makes the instance for form2<br />
a.show() ' shows the form2 on clicking of button1<br />
me.close ' for closing of form1(optional) <br />

What is mvarCsrDetails(CsrIndex.Title) ? It's obviously blowing up the COM object.

Should it probably be mvarCsrDetails(CsrIndex).Title
and mvarCsrDetails(CsrIndex).ID ??

Hello there.
I want to send SMS using a simple FAX Modem through TAP messaging protocol in .NET
What I know is that I need to connect to a message center number (be it free or paid access) through my modem and send it message which will then be sent to corresponding subscriber.
Could anyone guide me on some resources or libraries (probably free).
Thanks.

Howdy all,
I have a vb.net 2005 windows form. I created a strongly typed dataset, set the table type to 'Details' and dragged the table onto my form. Presto, a bound form which handles updates and even has a record navigator. There is a "+" button to add new reords. Great. Only problem is that the checkboxes on my form don't get set to unchecked/false on the new record. There are six checkboxes, and when I hit the plus button to create a new record the six checkboxes seem to be set based on the last record that was viewed..?? Really. Mmmm.
I checked the db and all six of the SQL 2005 Express fields that the checkboxes are bound to have a default value of ((0)). The check boxes were comming up indeterminate (green block) but now they just take the value from the previous record. I'm also cornfused about the two checkbox properties Checked vs. CheckState. I found a couple MSDN articles about Checked vs. CheckeState, but none of them actually said how to set these properties to get defaults to work..
Anyone know what I'm missing??
Thanks if you can, or even just for reading...
Bad checkbox, bad, bad!!

Maybe what you want is a Panel (or PictureBox), then you can paint/see exactly what you
want; the events would be slightly different of course.

I'm using a streamwriter to output 4 columns of data into a text file. Unfortunately the columns aren't lining up correctly. I've tried using Controlchars.tab & vbTab which do not work. Is there any way to create tabs in the writeline method or would I need to switch to a rich text file for this?
If anyone can help it would be greatly appreciated! Oh yeah I'm using Visual Basic 2003.
