No idea. Like I said, I don't have anything to test it on.

First post I think so be nice! I have created a dll file using the systems.collections.generic namespace. I have built the dll file in V Studio 2005. I can now reference the dll from 2005 but not V Studio 2003. V Studio 2003 states the dll is invalid (me thinks poor backward compat from MS!) I know the generics was intoduced in .net 2.0 and is not available in any previous framework. I cannot upgrade out applications to 2005 at present as there are too many in the site. I know little about the application pools, is this the only way to get round the problem? Any suggestions as to how I can create a generic class to house a collection in 2003 would be greatly appreciated.

Kindest Regards

TSB

No, the .DLL IS valid and backwards compatibility isn't the problem here. The problem is that you cannot load two different versions of the .NET Framework runtime into the same process at the same time, which is what you're trying to do.

You have to write your 2003 code in 2005 in order to use Generics at all. The .NET 1.1 CLR doesn't support Generics, no matter how you write it in 2005.

The other problem you have is that you can't run two version of ASP.NET on the same IIS instance at the same time. You'll have to run two different instances, and two different applications(!) in order to get this to work. You CAN have ASP.NET 1.1 pages link to ASP.NET 2.0 pages. You just can't have both ASP.NET 1.1 and 2.0 running under the same IIS instance at the same time.

How to program an application to terminate automatically?

4-May-07 4:30

XML isn't a transport protocol, so "packet" doesn't have any meaning in XML.

You can find a bit more information on connecting to an EPP server here[^].

Have a timer and check the time for each event
and use Exit to end the application.

array of bytes into an array of string

Setup a Timer in your startup form, set it for a 60 second interval. Check the current time against your scheduled time and if they match, stop the timer and call End or Unload startupFormName.

I take it you're talking about VB6. You can find examples all over the web, like this one[^].

Peek and Poke don't exist in VB6. They also don't have any meaning under Windows since each process runs in it's own memory space, as if it was the only process running in the system.

Hi again,

I get the following error

"Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated."

Below is the code where I get this error.

Private Sub txtTextField_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtRoomNo.KeyPress
'A number, backspace and dot allowed only
If Not (e.KeyChar.IsNumber(e.KeyChar)) And Not (e.KeyChar.IsControl(e.KeyChar)) Then
e.Handled = True
End If
End Sub

Any ideas where I am going wrong or how to fix this problem?

hi dear,

first of all please be sure you handeled keypress event for Correct text box. Code provided by you shows that it handles keypress event of txtRoomNo , not of txtTextField.

use following code for allow a number, backspace and dot only

If Not (Char.IsControl(e.KeyChar)Or Char.IsNumber(e.KeyChar)Or e.KeyChar = ".") Then
e.Handled = True
End If

hope this helps

Methods Other than DTS to read large CSV file in VB 6.0

4-May-07 4:10

Do you need this value in your code somewhere? If so, it's easy enough to get at runtime without going to the registry to get it. This path is returned by Application.StartupPath.

Dim myAppPath As String = Application.StartupPath

If you wanted to write this value to the registry during the installation, you'd have to create a custom action to do it. You can find out more about custom actions here[^].
