I am trying to write a program using the usb port on a computer to interface with another processor to collect data. I took a look at the ms comm in vb6 and all I see are the standard serial and parallel ports. Am I missing something or it not a feature of VB6

This isn't even a feature in the .NET Framework. Your comparing the USB port to a Serial or Parallel port. This is simply not how this port works.
USB communication is done through the device drivers for the device you're trying to communicate with. If that device exposes a simulated "serial" port, then you can use that to talk to it. If not, you'll have to consult some kind of SDK for the device in question.

My application runs long and complex convertion, so i want to make it possible for the end-user to cancel this. However, as you may know, just placing a button does not help since any Visual Basic application is not able to let you use form elements while it is working.
How can i let the user cancel the process comfortably at any time?
|
|
|
|
|
Try this sample
Public Class Form1
Private bCancel as boolean
Private Sub DoLooping
While Not bCancel
Application.DoEvents()
'Do Something
End While
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
bCancel = True
End Sub
' You can also use thread.
End Class

Cheesy poor man approach - use a timer or application.doevents to let the cancel button be clicked.
Better approach - do long-running processing on a background thread. Rocky Lhotka's article (link below) provides a straightforward approach for controlling a task and providing for user cancellation. You can have it implemented in 2 hours.

Could not find stored procedure 'DBAuthenticate'.
--> cmdSelect.ExecuteNonQuery()
|
|
|

It's telling you that your database doesn't have a stored procedure called "DBAuthenticate". Either you got the SP name wrong in your code, or you're not connected to the database you think you are when this call was made.

i got the DBAuthenticate function but still the same error appears.how can i made the connection?or test the connection is there?
|
|
|
|
|
If you get this error, your connection is being made successfully. There are still the problems that I mentioned, plus the possibility that your code is either using an SQL account or running under a Windows account that does not have the permissions to execute that stored procedure.

Compiler Error Message: BC30516: Overload resolution failed because no accessible 'New' accepts this number of arguments.
objTicket = New FormsAuthenticationTicket(2, textUsername.Text, DateTime.Now.AddMinutes(30), False, dtrRoles)
i added the new sintaks as u told but this come up.

I think it's pretty obvious what the error means. You trying to create an object who's constructor, according the documentation, takes 3, 6, or 7 arguments. You've supplied 5 in your code. These[^] are the possibilities.

Hello,
I am developing a GUI prototype in the VB which comes with Visual Studio 2005. I am new with VB, so I believe it's a newbie question. Everything goes fine until I press "Rebuild All". When I press it, VB drops all my settings of anchors, docking etc. and centers everything. As a result, the main menu, toolbars, status bars all get centered instead of where I chose to dock them. I also tried to select "lock = true" hoping it will stop this behavior, but it does not help. There must be some way to keep the selected alignment properties, but how? Would appreciate any help. Thank you!

The question should be what's causing it to center everything. This is most definately NOT normal behavior.
Does it do this if you create a new project and then just put couple of buttons on the form?

It works fine with a new project. I must have screwed up somewhere, I will look for the source of this abnormality. Thanks!

Did you use any custom controls or non-standard controls not normally supplied by the ToolBox?

No, everything comes from the toolbox. Although this new toolbox in VS2005 is larger than that in VS.NET and offers some new properties. I have used lots of Table Layout Panels and Split Containers, also I use my own graphical resources, jpg files created in photoshop for backgrounds. I have also noticed that at some point VB became very slow while I was modifying the UI, it may be because of graphics though, need to check on it.

Define "lots"... All on one form?? Is there a form with "lots" of controls on it?
