you may be having scope issues. if your declaring a local variable in vb
with "Dim", then taht variable is only valid inside that block.
EX
sub main()
thing()
otherthing
end sub
private sub thing()
dim x as string = "Hello"
debug.writeline(x)
end sub
private sub otherthing()
debug.writeline(x) 'This line causes an error.
end sub
the second reference to 'x' causes an error because it was declared within a block.
to declare globals within a class or module,
use :
Private x as string = "Hello"
sub main()
thing()
otherthing()
end sub
private sub thing()
x = "Hello"
debug.writeline(x)
end sub
private sub otherthing()
debug.writeline(x & " Again") 'No error this time
end sub
Globals are just one answer to a scope issue. paramater passage and other techniques exist. you'll learn 'bout 'em sooner or later
Good Luck

You can use
AppActivate("Title of the application")<br />
SendKeys.Send(Keys.Enter)

I am looking for suggestions on how to accomplish the following;
I am writing an application that display folders (A - Z) in a treeview. When the user clicks on a folder - a list of companies is retrieved from the database to a dataset and then displayed in a listview w/ checkboxes.
Eventually I want to save the checked listview items to a separate database table - when the user clicks on an OK button. A CANCEL button is also available if the user decides not to proceed.
The issue that I am having is I am not sure what method I should use to save the checked items or where to store them until the user presses OK/CANCEL buttons. To further define - I know how to retrieve the checked items from the Listview but I am not sure where to store them (i.e. datatable?) until the OK/CANCEl buttons are clicked.
Thank you,

you done necessarily need to store these values anywhere - they are "stored" by virtue of the fact they are on-screen.
When the user clicks "OK" just get all the currently selected items and save it in whatever way you want.

Apparently my post was not completely clear . . .
When the user clicks on a folder - a list of companies is retrieved from the database to a dataset, therfore the listview values dynamically change each time the user clicks on a new folder. If the user checked 2 companies on the "A" folder - then clicked on the "B" folder - and went back to the "A" folder the items are no longer checked. Make sense?

Hi Aavesh ,
This is the code to validate User ID & Password from DataBase.
If u r using SQL
imports System.Data.SqlClient
Dim Command as SqlCommand
dim DR as SqlDataReader
Dim Con as new SqlConnection("Server=server name;DataBase=database name;User Id=login id; Password=password;")
write this code in a Button Click.
Dim strCommand as String ="Select * from Login_Table where UserName_Column= ' " & txtUser.Text & " ' and Password_Column= ' " & txtPassword.Text & " '"
Command = New SqlCommand(strCommand,Con)
Con.Open()
DR = Command.executeNonQuery()
Con.Close()
If DR.HasRows = True then
MsgBox("Welcome")
Else
MsgBox("User Name or Password invalid")
End If
Dr.Close

Try:
Me.tabcontrolname.SelectedTab = nameofthetab
or
Me.tabcontrolname.TabPages(x).Select() where x is the index of the tab you want selected

Go into the properties, under behaviors and you will find TabIndex, this gives you the order in which the buttons or anything on the screen that you can inter act with, the order in which the item is given focuse, if you want to move from one imput to the next, hope this helps.

run a port sniffer on the server and see if any of the ports used are blocked on the firewall, or rely on IP or layer 2 broadcasts.
it may be an SMTP relay issue as well. if your sec policy disables the right that might be it.
I would typically advise against sending email from SQL (at least SQL2000). we had issues with it at work.

If you're hoping to show a picture in a forum, how do you expect your code to be run ?
In general, a picturebox lets you easily show a picture, Image.FromFile will let you load an image from the file system.

hello guys anyone could help me on how to set column in MSHFlexGrid in VB.Net..... hope you can give a sample code.....
thanks! 
|
|

There is no .Net component called MSFlexGrid, It is a COM component.
Right Click MSFlexGrid control
Select properties
Select General tab
Now you can create columns and rows

you have used three arguments, wilde that's the error. You can use only two arguments according to this format
AxMSFlexGrid1.set_ColWidth(coloumn Number,width)
example
AxMSFlexGrid1.set_ColWidth(1,3000)
