activex download problem

I have created and included an activex component that is embedded in an aspx page using <object classid="http:mybin/bydll.dll#method<br" mode="hold">
Everthing works fine on some machines. However, I have two client machines running windows xp and ie 7, that will not download the activex control.

I have modified the .Net zones appropriately to use FullTrust (trusted sites and internet(for testing purposes).

I have modified the browser security settings to allow active x controls to be downloaded.

For a few machines, this download does not work. Does anyone have any ideas as to what I can check, read, test to understand why a download is not taking place on a few machines?

Thanks

Are they the only machines that have IE7 that you've tested on ? Sounds like IE7 has made things tighter and you can't get through.

Thanks for the reply. All of the machines that it has successfully downloaded the control to have been on IE7. I have adjusted security settings in both the .NET configuration tool and the browser, but to no avail on the two machines I am having a problem with.

Limit the movement of scrolling Picture

VB6: I have a picture on form and I currently have code that will allow the mousewheel scroll the picture up and down, but I am not sure how to set a limit or how to prevent the picture from scrolling out of view. Below is my code, any suggestions:

'**************************************
Private Sub ProcessMessages()Dim Message As Msg
Do While Not bCancel    
WaitMessage    
 If PeekMessage(Message, Me.hWnd, WM_MOUSEWHEEL, WM_MOUSEWHEEL, PM_REMOVE) Then        
  If Message.wParam &lt; 0 Then             
    Picture1.Top = Picture1.Top + 240        
    Else            
    Picture1.Top = Picture1.Top - 240        
   End If    
 End If    
DoEventsLoop
End Sub
'**************************************</pre>

Soooo, how many times a day are you going to ask this question? How long before you relize that it's very unlikely you're going to get an answer to it?? I for one, haven't used VB6 in 7 years.

What is this the 3rd or 4th time today? I mean I understood the second repost because the way he formatted his code was horrific, but now someone is desperately just avoiding google and alternative methods of research.

Stop the reposting, no one here is obligated to help you, and if they didn't by now, chances are it isn't going to happen.

Comboboxes and Collections

Hi everybody,

I'm VERY new to VB and need some guidance...it may be that I am just over complicating things by what I'm doing though - or what I am asking might not be possible - but here goes!!

I am writing a new app from scratch for my current employers and I have a few classes that are used to handle data access and management.

I have a class that represents a "Shop", so it has a shop number, address lines etc.

I have a seperate class called "Shops" which inherits from CollectionBase. The Items in Shops.List are populated by "Shop" objects. So I have a method called populatelist which uses a SqlDataReader to return a list of customer shops. I then traverse this list and create a "Shop" using field values in each datarow. I then Add(Shop) which populates my collection list.

This all seems to work fine.

However I want to connect my "Shops" collection to a combobox, so I tried code like the following: -

Dim aBind As New BindingSource

aBind.DataSource = oShopList
cboShopList.DataSource = aBind

cboShopList.DisplayMember = "ShopName"
cboShopList.ValueMember = "ShopNumber"

cboShopList.DataBindings.Clear()
cboShopList.DataBindings.Add("SelectedValue", aBind, "ShopNumber")

This populates the combo correctly, and refreshes nicely when I change customer.

BUT when I test my combobox, I get erratic results. I test what value the combobox returns and it changes sometimes when I change the selection, sometimes not. Whichever item I pick in the list, the display part of the combo always displays the first item after briefly displaying the item I chose...even when it sometimes changes the ValueMembers value...

I am using VB.Net 2.0 and the app is your bog standard, run-of-the-mill windows application.

Like I say, I'm new so not sure if I am way off beam here, but any advice at this point would be helpful!

Cheers,

A seriously LostMonkey...

Creating Logon screen with SQL Connection

Why not just use a list of shops ? What does using your own class give you ?

What is a bindingsource ? Why do you need that in the middle ? Your datasource should work just pointing to your list.

I also don't see why you need the DataBindings. What do they do ? I'd just set the datasource to oShopList, and set the Display and Value members.

Do you know other languages and you're new to VB ? What other languages do you know ?

I have just started creating a new vb application which requires a login screen.

I have created a new database in sql server 2000 which holds the usernames and passwords.

I was wondering how i would create the connection and then link the username and password text boxes to the fields in the database.

Regards.

I would highly recommend picking up a book on VB.NET and SQL Server and working through them before taking this project on. The code you're written so far is terrible and if you continue to use the techniques you've demonstrated so far, your project is going to fail miserably.

I have recently read a VB book, as you can imagine, i am a complete novice when it comes to vb and programming. I have written this piece of code. I was wondering if you could tell me if this would create a valid connection or not.

Imports System
Imports System.Data
Imports System.Data.SqlClient

Public Class frmLogin
Public sqlconnection As SqlConnection = New SqlConnection("Data Source=TG-IT-TPSRV;Initial Catalog=AFQ;User ID=sa;Password=;")
Public Sub frmLogin()

Dim sqlConn As SqlConnection = sqlconnection
Dim sqlComm As String = ("SELECT * FROM Users")

End Sub

Private Sub BtnCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCancel.Click
Me.Close()
End Sub

Public Sub Logon_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub

Private Sub BtnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click

Dim sConnectionString As String = "Source=TG-IT-TPSRV;Initial Catalog=AFQ;User ID=sa;Password=;"
Dim objConn As New SqlConnection(sConnectionString)
Dim sqlComm As String = ("SELECT * FROM Users")
Dim objComm As New SqlCommand(sqlComm, sqlconnection)
objConn.Open()

End Sub
End Class

Yeah, it would create a connection, but your design is going to cause you problems down the road.

On your main mdiForm in the Load event show the splash screen

Private _splash As SplashScreen

Sub Form_Load() Handles Me.Load
_splash = New SplashScreen
_splash.Show(Me)
End Sub

Then in the Shown event close the splash Screen

Sub Form_Shown() Handles Me.Shown
_splash = New SplashScreen
_splash.Close
_splash.Dispose
_splash = Nothing
End Sub

2008? There's a Splash Screen component built in. All you have to do is right-your project in the Solution Explorer, and click Add New Item... It's in the list that shows up. Everything is already done for you.
