I'm trying to create an aplication in VB 2005 that automatically (just by clicking one button) opens a web page, inserts an ID and a password on two text fields, clicks a button in the page and then takes all the information from that page and shows it in the VB application.
My problem is that I dont know how to program my application to insert text and click buttons automatically.
I been checking the webresponse and webrequest classes but I have no idea if those can solve the problem.
Thanks

I need to check files for having no content. I will possibly be checking some large files, is checking for a .Peek return of -1 sufficient and faster for this purpose?
I just discovered My.Computer.FileSystem.GetFileInfo(File).Length = 0 which I suppose it probably the best way to go.

Yup, I think checking the file size is the best way to go.

Hello
I am trying to put flashing text in lbl box in this project and i am new in ve.net i have try this code but it's not working so please can anybody help me how to do this
wating for your kind rep.
Private Sub btnBeep_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBeep.Click<br />
'toggle timer and botton text<br />
timBeep.Enabled = Not (timBeep.Enabled)<br />
If timBeep.Enabled Then<br />
btnBeep.Text = "&Stop Beeping"<br />
Else<br />
btnBeep.Text = "&Start Beeping"<br />
End If<br />
End Sub<br />
<br />
Private Sub timBeep_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles timBeep.Tick<br />
Dim Flash As String<br />
Beep()<br />
If lblTimer.Text = Flash Then<br />
lblTimer.Text = ""<br />
Else<br />
lblTimer.Text = Flash<br />
End If<br />
End Sub<br />
End Class

According to your timeBeep_Tick procedure you have assigned an empty value to Flash variable and also in IF statement you are saying that if LblTimer.Text is empty and then set lbltimer.text to flash (what means to nothing). I think you should double check your IF statement. IF block will return LBLTimer.Text always empty because Flash value is not changing.
Tell me when Flash variable changes its value?
What a curious mind needs to discover knowledge is noting else than a pin-hole.

Flash would need to be declared globally so it's value persists. You would initialize it when you start the timer so that it equals the text in the label. As an alternative you could set the text's font color to match the backcolor to hide it.

Can you save a range of items in a listbox as a datatype, like a collection for adding to an Access Database??
If not then how do you loop thorough the listbox adding each one to a seperate column in an Access table?
Thanks
|
|
|
|

I belive what is more easy if you first save the values of listbox in an array, then send these datas to database by a cicle filling a recorset to update or with sql instructions.

I want to add a sound when a form loads, can I simply add the sound as a resource and then just make a statement like my.resource...blaablaablaa .play, or is it a lot more complicated than that?
Also, can i use mp3 or am i stuck with wav?
Cheers

Just use: My.Computer.Audio.Play(My.Resources.(YourFile), AudioPlayMode.WaitToComplete).

Unless you want to embed Windows Media Player into your app (which would be a pain), you can only use .wav files. Hope this helps.

its generated by webmatrix.. but its just not updating a field that is already in the table which has a string value...don't know why..
Dim queryString As String = "UPDATE [R_Application] SET [Fname]=@Fname, [Mname]=@Mname, [Lname]=@Lname WHERE (" & _
"[R_Application].[AppId] = @AppId)"
if the field was null then it works..but if some value exist..it doesn't update...

Is this the same query it always uses?

yes same query..what wrong with it?... just do one and send it to me..let me try it

You have to show more of your code.
What you describe doesn't make sense if one only looks at the SQL query. An update query doesn't care if the value in the field is null or not, it updates the field in either case.

Ok..this is the exact query i am using....
Function testUpdate(ByVal appId As Integer, ByVal fname As String, ByVal lname As String) As Integer
Dim connectionString As String = "server='(local)'; trusted_connection=true; database='TESTDBfhms'"
Dim dbConnection As System.Data.IDbConnection = New System.Data.SqlClient.SqlConnection(connectionString)
Dim queryString As String = "UPDATE [R_Application] SET [Fname]=@Fname, [Lname]=@Lname WHERE ([R_Application]."& _
"[AppId] = @AppId)"
Dim dbCommand As System.Data.IDbCommand = New System.Data.SqlClient.SqlCommand
dbCommand.CommandText = queryString
dbCommand.Connection = dbConnection
Dim dbParam_appId As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_appId.ParameterName = "@AppId"
dbParam_appId.Value = appId
dbParam_appId.DbType = System.Data.DbType.Int32
dbCommand.Parameters.Add(dbParam_appId)
Dim dbParam_fname As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_fname.ParameterName = "@Fname"
dbParam_fname.Value = fname
dbParam_fname.DbType = System.Data.DbType.[String]
dbCommand.Parameters.Add(dbParam_fname)
Dim dbParam_lname As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_lname.ParameterName = "@Lname"
dbParam_lname.Value = lname
dbParam_lname.DbType = System.Data.DbType.[String]
dbCommand.Parameters.Add(dbParam_lname)
Dim rowsAffected As Integer = 0
dbConnection.Open
Try
rowsAffected = dbCommand.ExecuteNonQuery
Finally
dbConnection.Close
End Try
Return rowsAffected
End Function

There is nothing wrong with that code.
Debug the code and watch where you get the values from, as I suggested in the other thread.

I cant seem to remember how to record keystrokes. Basically i need to use the keystroke value in an IF Statement to say,
if back or delete were pressed then
end if
thanks in advance

The windows form as a KeyPress event that you can look at to retrieve the keystroke.

Here is some code that should work for you...
Private Sub yourtextbox_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles yourtextbox.KeyDown
'Only allow some control keys
If e.KeyValue = Keys.Delete OrElse e.KeyValue = Keys.Back Then
'good key press
Else
e.Handled = True
End If
End Sub
Hope that helps.

use the key down event handler as below
Private Sub txtTendered_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtTendered.KeyDown
If e.KeyCode = Keys.delete Then
do something here
elseif e.keycode = keys.enter then
do something else
end if
end sub
hope this helps
