Where are you hoping for the text to go then ? Sounds like the problem is one of focus in IE, the right place doesn't have input focus when you send the key strokes.

I've actually able to get focus to the IE window, but for some reason the Sendkeys function must not actually simulate keystrokes... i'm sending the string to the window in general, the text does not actually show up anywhere... this is why i simply need to simulate the actual keys being pressed
thanks for the site tho! i'm definitely looking into it further

Then it's homework. How do YOU think it should be done ? Do you know what an array is ? What do you know about working with arrays ?

Hi to all,
1.can I create a formulas for columns like in excel
2.can I navigate through a row by pressing enter key
|
|
|
|

1 - no, not without writing the code yourself. It's not Excel, it's a grid
2 - sure, just write the code to handle the keypress and change the selection.

I am trying to simulate the Microsoft Excel "Freeze Panes" function on a Visual Basic .NET form using two ListView controls.
Key_ListView: The control on the left will have one column entitled "Key" and have a numerical value.
Data_ListView: The control on the right will have about 30 columns. The 30 columns can't fit onto the screen at the same time. The user has to use the horizontal scroll bar to see the columns out of view.
When the user scrolls the Data_ListView to the right (horizontal scroll bar) they will not lose "sight" of the key value in the Key_ListView. This is the functionality my users demand.
When the user scrolls the Data_ListView Up and Down (vertical scroll bar) I want the Key_ListView to scroll Up and Down as well. I want the records to stay in sync with each other in a vertical nature.
Using the .EnsureVisible property doesn't set the scroll position; it just makes sure the specific item is "somewhere" in the client window.
Thanks in advance for your help.

Goto your project's properties and check Make Single Instance Application.
Trinity: Neo... nobody has ever done this before.

thanks Ben too much , but is there any way short than all that code ?
regards

You can leave out the windows message part since that is only used to activate the application if it is already running. All you have to do is use the mutex to know if your application is already running.

hi buddy...
if you are working in VB try this...
Private Sub Form_Load()
If App.PrevInstance = True Then
MsgBox "application already running", _
vbInformation, "Message"
End
End If
End Sub

i m usin data reader in my login form.
wat i want to do is by data reader i can read data from tables
that i created. n be able to open other forms accordingly.
.....the problem is that that when i run the application,,no matter what i type
it only shows me the matter of first text box "you r logged on as student".....
here is the code
Imports System.Windows.Forms.Form
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlClient.SqlCommand
Public Class logon
Inherits System.Windows.Forms.Form
Dim objsqlconn As SqlConnection
Dim logonselect As String = "select * from logon"
Dim objsqlcmd As New SqlCommand(logonselect, objsqlconn)
Dim dr As SqlDataReader
Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
objsqlconn = New SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Documents and Settings\Administrator.WINXP_PRO_CORP.002\Desktop\WindowsApplication1\WindowsApplication1\Database1.mdf;Integrated Security=True;User Instance=True")
objsqlcmd = New SqlCommand
objsqlcmd.Connection = objsqlconn
objsqlconn.Open()
objsqlcmd.CommandType = Data.CommandType.Text
objsqlcmd.CommandText = "select * from logon"
dr = objsqlcmd.ExecuteReader()
Dim str As String
Dim a As New mdiparent
While dr.Read()
str = dr.GetString(0)
If str = "student" Then
MessageBox.Show("you are loged on as student")

End If
If str = "administrator" Then
MessageBox.Show("you are loged on as administrator")
a.Show()
End If
If str = "lass1" Or "lass2" Or "lass3" Or "lass4" Or "lass5" Or "lass6" Or "lass7" Or "lass8" Then
MessageBox.Show("you are loged on as lab assistant")
a.Show()
End If
End While
dr.Close()
objsqlconn.Close()
End Sub
Private Sub logon_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
TextBox1.Text = ""
TextBox2.Text = ""
TextBox3.Focus()
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Dispose()
End Sub
End Class
can somebody please tell me where the problem is????

You are not doing any filtering on your query. Do you only have one row in the database? Have you checked what str = dr.GetString(0) actually returns?
|
|
|
|
|
and also to make sure that the changes have been made.
i m using vb.net express edition 2005. i m being able to delete the row at
rum time.but it appear again,,if i stop n run the form again
please help

Hi,
The datagrid control only shows data, and allows you and/or the user to manipulate that data. deleting a row from the datagrid doesn't automatically delete it from the datagrid's data source.
So the question is, what do you use as the data source for your datagrid, and how did you bind it to it? If it is a datatable, how do you populate it? If it is a dataset, where does the dataset get its data from?
Or in other words, deleting the row from the datagrid only affects what you see at that moment. You will have to delete the row from the data source as well.
Good luck,
Johan
My advice is free, and you may get what you paid for.

I know this is probably real simple but for some reason I can't figure it out...
how can I code my own custom eyedropper? Or something which can get the color of any specified pixel on the screen?
thanks!

I came across a VB 2003 IDE quirk. If you have variables referenced in a select case stament in a sub the quick watch window seems to have trouble interacting with ide and cannot display the value of the variable.
Specifically, I had a datatable defined inside the case statement. If I would add the datatable to the watch window all of its properties displayed "Error: cannot display value" in the value section of the watch. However wehen I moved all of the code in the case statement into its own sub the watch window behaved as i expected.
Not sure whats going on there, be refactoring the sub made things cleaner anyway.

Hi. Which type of dialog box can I use to show an information message while the code is running behind? The MessageBox stops the execution until the user press ok button.
I have a long process in an application, but can't use a progress bar because the process is called from just one code line that calls a dll method.
Regards,
Diego F.
