I have made a user control That inherits Windows.forms.Label.
Now what i require is i want to disable some events of Windows.forms.Label to User of that UserControl (Name is LinkLable).
i.e. Label has an Event onPaint. now if some user invokes LinkLable to his form he must not be able to write a code for LinkLable.
When I run this code it give this error
""Mailbox unavailable. The server response was: 5.7.3 Requested action aborted; user not authenticated"".
The code:
Dim mail As New MailMessage()
Dim SmtpServer As New SmtpClient
SmtpServer.Credentials = New Net.NetworkCredential(TextBox1.Text, TextBox5.Text)
ProgressBar1.Value = 10
SmtpServer.Port = 587

I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically.

how to do it ?
i am using two timers for the purpose to elapse the time but it is hard to call the function for every control + event

I made a custom control for my form. It's basically a custom button I made using a label.The only problem is, when I apply a myButton_Click event to the control in my main form, it will only be triggered if the control itself is clicked. The label takes up the entire form (it's docked inside it). The click event isn't triggered when the control (virtually the label) is clicked. You must click behind the label (the form's background) for the event to be triggered. How can I pass the myButton_Click event to the label so it is triggered when the label is clicked? I hope I'm making sense.
View 9 Repliesso here's my code. I'm testing to see if a user exists on the server before I let them log in.
'Creates test file
Dim write As New StreamWriter("c:/test.ping")
write.Write("This is a test string used to log in a user.")
write.Close()
[Code]...
Dim mStream As Stream = mReq.GetRequestStream()Another strange thing: the streamwriter won't write to C:/test.ping. I changed it to E:/test.ping and it wrote (E is my Ext HDD) but I still got the same answer.I'm using Windows 7 Home Professional. On my old XP PC I got it to work but that was a while ago.
I like to build objects that contain properties and also functions / subs to do work. I dont have a lot of other programmers around me to answer this question so I thought id ask. If my goal is to make a function or even sub part of a class blue print is it better to do it by making a seperate class for the function, and then construct a new copy of the classFunction as a property of the parent class or is it better to simply put the function in the parent class.

In order to take advantage of the spell checking ability of WPF textboxes, I have added one to a user control (with the use of elementhost). This user control is used in various window forms. My current problem is trying to handle keyup events from this textbox but the windows form is unable to "get" any event from the control. I can access the properties of the textbox just fine (i.e. text, length, etc.) but keyboard events don't seem to work.I have found, however, that the following will bring back events from the WPF textbox:
Public Class MyUserControl
Private _elementHost As New ElementHost
Private _wpfTextbox As New System.Windows.Controls.Textbox
[code].....
The user control is now able to do something after the PreviewKeyUp event is fired in the WPF textbox. Now, I'm not completely sure how to have the window form containing this user control to work with this.

I've created an application that is supposed to map a network drive as soon as it starts using this basic sub:
Private Sub DesktopAssistant_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'ElevatePrivileges()
'System.Diagnostics.Process.Start("batch\mapfs.bat")

Here is the code for the MapDrive function:

Module map_unmapdrive

It works perfectly fine when I start the application, but when I do RunAs and start the application as another user, the MapDrive function does not seem to execute. Everything else in the application works when running as another user, just not on-load events.
I have created a base class for some user controls, then I created controls that inherit this class. This is so I can CTYPE the inherited controls back to the base class and refer to properties, methods and events in a common interface. The base class declares has some Public Event BLAH(Sender as object, e as EventArgs) declarations. The derived class then has Public Shadows Event BLAH(Sender as object, e as eventargs) declarations. My parent form adds handlers for the BLAH event. When the derived class fires the event, though, it does not get raised to the parent form.

My application connects to several SQL Server instances (Using SMO and ADO.net), these connections are all closed properly (I'm using Using), one connection is a SqlDependency for table change notification.
Part of the application establishes an encapsulated VPN connection to a remote system, this causes all network resources to be unavailable, including the SQL instances.
What would be recommended method of handling this scenario? Where a networksql disconnect is frequent but predictable.
I'm using connection pooling so have no control over re-establishing a connection, if I attempt to open a connection (Which retrieves an available connection from the pool) it will fail as soon as I attempt to use it. (As pooled connections are not tested to save overhead).

is it possible to link a personal created class with a Mouse Event? I created a class and I want to make it possible to make it interactive with the mouse.

I am trying to make a small control that has a picturebox and a few labels that can be dragged on the form it is placed on. The control was easy, and I can drag it fine when the mouse is down on the control, where there are no other controls, like not over the picturebox or labels.
When i try to click and drag the user-control and the mouse is on the picture box or labels of the control the mouse down event is not detected. I am hoping someone can tell me how to pass the mouse-down event from the controls on the user-control so the form I place it on detects the mouse down even no matter where on the control i click.
