The button being highlighted means that it has focus. The textbox being highlighted means that the textbox has focus.
If the button is 'highlighted' (if it has the focus) then the cursor is standing on that button. (You can't see it, but if you press the spacebar, you'll interact with the control that has focus - the button).
Only one control can have the input-focus at a time.

I knew there was a solution. You are not supposed to mess around with the focus for the submit button. If you set the acceptbutton property of the form to the button you want, then it will always be highlighted and when you press enter it will be pressed.

Hi there! I need some help with events for dynamicly created objects. The code below illustrates the problem. My situation will be a little different since the objects I will be dynamicly creating will be custom, but the problem is the same.
The event will only fire on the last created object. How can I have an event fired within the form Class each time an individual instance of the label is clicked??
Public Class Form1
Friend WithEvents lbl As Label
Private i As Integer
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
i = 1
End Sub
Private Sub Form1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseUp
lbl = New Label
lbl.Name = "lbl" & i
lbl.Text = "Label " & i
lbl.Location = e.Location
lbl.AutoSize = True
Me.Controls.Add(lbl)
i += 1
End Sub
Private Sub lbl_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbl.Click
MsgBox(lbl.Text)
End Sub
End Class

This code won't work. You only have one label wired up with it. Basically, you can't use WithEvents on a class-level variable and expect this to work. Drop the "Friend WithEvents..." line completely. Your MouseUp code has to create the label and wire up the events itself. This way, every label you create will maintain event connections.
Private Sub Form1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseUp
Dim lbl As New Label
' lbl.Name = "lbl" & i ' Drop this line. It's not necessary
lbl.Text = "Label " & i
lbl.Location = e.Location
lbl.AutoSize = True
AddHandler lbl.Click, AddressOf lbl_Click
Me.Controls.Add(lbl)
i += 1
End Sub
and drop the "Handles lbl.Click" from the end of the Sub you defined.

Hi,
my application wit database accsess is running fine on the System I developed it. When distibuting it on a other PC - without installation - I get the error message "Can't find System.EnterpriseServices.Wrapper.dll or one of it's dependencies". In former times this method worked fine but no I have a new target system. Is there a workaround for that.

adapter.Fill(dt)

For Each dc In dt.Columns()
....

You shouldn't be doing this from your code. This should be done at installation time, by the installer. I'm not even sure it would work if you tried to do it from code.

Actually issue is that i designed one C# activeX control and that is embeddded inside 1 html .
Whenever any user request that page control is visible but if requested person do any thing related to that control.
The Control is not allowed access to resources of that machine by CAS of .NET runtime.
and exception thrown is System.Security.Permission.UIPermission.
and throws repeatedly as soon as mouse is over the control.
I am not getting how to deal with this problem.
Any help will be appreciated
Thanks in advance!!!

Whoah - you want to do this from a webpage? You can't, and when you stop and think about it for a minute, you'll see why. If you could elevate privileges from a website, then any site you visit could host a malicious control that increased its privileges and started to crawl your hard drive looking for useful information, or add a virus. This is part of the reason why these controls are sandboxed.
|
|
|
|
|
Like Pete said, you cannot do this. Code running inside a browser runs inside a heavily restricted sandbox. That code cannot evelate its own privileges and any code you put into that control has to be written to abide by those restrictions.

Hello,
I have SQL database and I need to Alter a Relationship in my Table.
There Is an Employee Table with Employee ID and Another Table that has Employee ID as foreign Key.
I need a Query to update this relationship to Add the functionality of CASCADE ON DELETE RECORDS.
Please Anyone has any ideas, i am relatively new to SQL.
Thanks In Advance.

|

First, you have to drop the Foreign Key Constraint and then recreate it with the desired options.
ALTER TABLE <table_name>
DROP CONSTRAINT <foreign_key_name> ;
ALTER TABLE <table_name>
ADD CONSTRAINT <foreign_key_name> FOREIGN KEY (EmployeeID)
REFERENCES <other_table_name>.EmployeeID (EmployeeID) ON DELETE CASCADE ;
Keep It Simple Stupid! (KISS)

Hi there,
with Windows 7 there came a neat new feature in the superbar. You can display progress inside the taskbar icon.
The linked image below shows the download progress of a file, to illustrate what I mean.
http://bb.nfshost.com/progressBar.JPG[^]
Does anyone happen to know if this feature can already be implemented through .net code? I'd love to have this in an FTP upload application that I only use for myself, on a Windows 7 system.
Any hints would be welcome
Cheers

In the sense you are speaking of, I would say not. it is possible to create a child window in the taskbar that is sort of like a toolbar (ex: Windows Media Player), however it would not be exactly like a taskbar icon. I am sure their are some Windows 7 specific APIs that you may be able to work with, but that is uncharted territory with Windows 7 still being in beta.

I figured it out - if your app uses IProgressDialog it's done automagically. I hope they add that for ProgressBar aswell in the release version.
