You don't need it. The TCP/IP configuration is usually setup with the proper gateway address already. The gateway has nothing to do with a proxy anyway. That's seperate, but on smaller broadband routers for the home, a proxy/NAT/firewall is usually found on the same device at the same address.
If Internet Explorer works for outside sites, you don't have to worry about setting up proxy settings. The Inet control uses the proxy settings in IE automatically.

but how to solve the problem whitch i have meet
|
|
|
|

I already told you, you're going to have to examine the page headers and content returned from the page request so you can figure out where the difference is when you request the page via the proxy compared to when you aren't forced to use a proxy.

Hello,
Does anyone know how to enable paging on a datagrid using adodc connection? So far I have almost 1000 records that needs to be displayed. This query dsplays via scroll bar. I'd like divide these records by page. Thanks in advance!
Sorry I forgot to mention I'm doing a windows application not web. I've weird thing is AllowPaging is not available in datagrid option or in any other options. Any help would be much appreciated. Thanks again!

As far as I can remember, there is no paging "option" on the old grids. You had to implement it yourself providing code and SQL to grab the next/previous page from the database and bind to that.

Ahh...that explains why I can't find that darn paging option. So it has to be done the long way...Many thanks friend!

Hi,
I'm doing a vb.net (Window Application) project.
I'm retrieving data to a datagrid. It has checkbox at the 1st column (DataGridBoolColumn).
User is able to check or uncheck the rows in datagrid.
Once user click save, how can i insert those rows where checkbox is selected into SQL table?
I found few samples but those are for asp.net.
Can anyone advice me as i'm using window application.
Thanks in advanced.
cheers,eunice

Hello Euince,
You would have to manually insert the rows into SQL table by looping through the rows and check if
the first column is checked or not.

Hi Allen,
Thanks for the tips. But how can i loop through?
Is it something like this?
For i = 0 To icounter - 1
If myTable.Rows(0).Item("check") = True Then
Dim RawID As Object = dgResult.Item(i, 2)
Dim Question As Object = dgResult.Item(i, 3)
strQuery = "Insert into udtInsert (RawID,Question) values(" & RawID.ToString() & ",'" & Question.ToString() & "' )"
conn.Open()
cmd.CommandText = strQuery
cmd.Connection = conn
End If
Next
pls advice... thanks a lot.
cheers,eunice

Hi,
i have designed a new control with some propertys. Some of the propertys should only at runtime be available, not at designtime.
Codesample:
<system.componentmodel.designtimevisibleattribute(false)> _
Public Property MyProperty As Boolean
Get
......
This doesn't work.
But
<system.componentmodel.designonly(true)> _
Public Property MyProperty As Boolean
Get
......
works fine, property is only avialable at designtime, not at runtime.
Something like RuntimeOnly is missing ?!
Any comments ?

You didn't check the "Ignore HTML tags in this message" box at the bottom of your post before you hit "Post Message", so some of your code is missing from your post.
But, hiding a public property from the PropertyGrid (Designer) is easy. All you have to do is specify the Browsable attribute on your property.
<Browsable(False)> _
Public Property MyProperty() As Integer
...
End Property
|
|
|
|
|
Dave,
your
<Browsable(False)> _
Public Property MyProperty() As Integer
... End Property
prevents the property to be accessed with the property window. But the designer still generates code to set the property.
Okay, i can code <DesignerSerializationVisibility ....>, so no code setting the property is generated.
But placing the control on any form executes the Get Method of the Property.
How to create a Property which is only avialable at runtime and excutes only at runtime ???
Something like the opposite of <System.ComponentModel.DesignOnly(True)> seems to be missing.
regards
bauer

In the property code, check the DesignMode property to see if it's being used in the designer. There are pitfalls to doing this, though. The DesignMode property isn't known for its reliability.
Public Property SomeProperty As Integer
Get
If Me.DesignMode Then
' The control is being used on a design surface...
Else
' The control is NOT being used a design surface...
End If
End Get
...
End Property

Dave,
thank you very much, for your quick reply.
I think, this coding (Process.GetCurrentProcess.ProcessName = "devenv") isnn't much better ?!

iam using select case statement .in this iwant to work with two select statements by which one select statement works on the user eneterd value and other select statement should work for every select case ..is it possible
|
|
|
|
|
Like another control statement the case statement could also be nested but nested will give the complex code to you so i suggest you to call function so on select statement you could call the function according to the values entered by user.

Great job on completing it yourself. However, you should post the code that let to your solution, so if any other member here has the same problem, they may stumble upon your post and be able to fix theirs quickly!

Private Sub cmdSaveDB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSaveDB.Click
If picShowPicture.Image Is Nothing Then Exit Sub
Dim ms As MemoryStream = New MemoryStream
picShowPicture.Image.Save(ms, ImageFormat.Jpeg)
Dim bytBLOBData(ms.Length - 1) As Byte
ms.Position = 0
ms.Read(bytBLOBData, 0, ms.Length)
Dim prm As New MySql.Data.MySqlClient.MySqlParameter("@BLOBData", _
MySql.Data.MySqlClient.MySqlDbType.Blob, _
bytBLOBData.Length, ParameterDirection.Input, False, _
0, 0, Nothing, DataRowVersion.Current, bytBLOBData)
Dim ConnectionString As String = "SERVER=localhost;" & _
"PORT=3306;DATABASE=pictureDB;User Id=root;" & _
"PASSWORD=pass;"
Dim QueryString As String = "INSERT INTO blobtest ( BLOBData ) VALUES ( @BLOBData )"
MsgBox(QueryString)
Dim myConnection As New MySqlConnection(ConnectionString)
Dim myCommand As New MySqlCommand(QueryString)
myCommand.Connection = myConnection
myCommand.Parameters.Add(prm)
'Open the connection
myConnection.Open()
'Execute the query
myCommand.ExecuteNonQuery()
'Close the connection
myConnection.Close()
End Sub
But it is giving me a error saying imageformat is not declared.. How to solve it.. Plse help me..

Please read on how to ask good questions, 'please help me' is not a reasonable header. Everyone here wants help.
Which line gives the error ? As the word 'ImageFormat' does not appear in the code you pasted, I assume it's not one of these lines ? Have you tried using the debugger ?
This is what happens if you copy code off the web at random, articles and code snippets are great, but you need to take the time to understand them before you use them.

You have to import the namespaces that the code uses.
If you look up ImageFormat in the documentation, you see that it's in the System.Drawing.Imaging namespace.
Despite everything, the person most likely to be fooling you next is yourself.
