VS 2008 - Handle Leave Event For Multiple Textboxes

Aug 23, 2011

Is there another way to handle the leave event of multiple textboxes other then coding in each event handler? I may not be using correct terms instead of doing this: (Existing)
Private Sub leveladjstvaltxt_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles leveladjstvaltxt.Leave
If Me.leveladjstvaltxt.Text <> "" Then
Dim levels As Integer = CInt(Me.leveladjstvaltxt.Text)
Me.leveladjstvaltxt.Text = Format(levels, "#,###")

I have 30 TextBoxes all need same formatting , so I was trying to come up with something like this: (trying)
For Each ctrl As Control In Me.Controls
If TypeOf ctrl Is TextBox And ctrl.Text <> "" Then
Dim val As Double = CDbl(ctrl.Text)
CType(ctrl, TextBox).Text = Format(val, "#,###")
End If

I am stuck though and don't know where I would place that code if this is something that is even possible. Only thing I can currently think of is in the leave event which defeats the purpose, I wanted to avoid having to place the code in 30 different textoxes leave event.

Handle Multiple Dropdown Lists In ASP.net?

Aug 16, 2011

One of my clients wants a set up multiple dropdown lists as a set of outbound links (yes, I cringed too, but he does have his reasons. there are 3 dropdowns, each one pertaining to its own group of links. When each dropdown has its SelectedIndexChanged, it then redirects based on the choice made. However, lets say I make a choice in the second dropdown. It goes to the proper link. If I then choose a link in the first dropdown, it goes to the proper link. Then if I select a link in the third dropdown, it will go to the link specified in the choice I made in the FIRST dropdown.

How can I code it so that it will always select the most recent selection?

How To Handle Processing Multiple Commands

Jul 15, 2010

I am making a program which will read data from csv and pick up Username & Computer name from the csv.

Then it will run commands via telnet with those username and computer on line at a time. I have reached this goal without any problem. I wanted to paste the code here but its too much.

Basically what i now want to do is have a option for user to skip a command.

Like if csv have 3 users in it. i.e.

j.doe, comp1
t.test, comp2
u.user, comp3

Popup will come and say do you want to run the command "add user j.doe, comp1" something and you will have option to say Yes, No , Cancel.

Where yes will run the command and no will skip that user (go to next one) and cancel will end the whole process.

I know Msgbox yes,no is there but i dont know how to skip that user.

Following is the code which migh

vb
Dim objCmdSelect As New OleDbCommand("SELECT * FROM " & fileNam & "", objConn)
For i = 0 To objDataset1.Tables(0).Rows.Count - 1

Handle Multiple Moving / Scrolling Labels

Feb 25, 2010

I have an application which I've designed to relay information on a large screen, like news feeds etc. It scrolls labels inside panels so the text moves in a readable fashion. It actually works quite well but it seems to struggle sometimes by consuming too many CPU cycles. I've turned on double-buffering on the form as I remember this graphics method from years ago. This improves the display drawing in general but I am still getting flickering and sometimes the scrolling slows down considerably.

Sub To Handle Multiple KeyPressEventArgs (null Reference)?

Apr 22, 2011

I am using KeyPressEventArgs to restrict several text boxes to numeric entries only. Rather than repeat the code, I thought I would make a "RestrictToNumeric" subroutine and call it from each "KeyPress" event. Like So:

Private Sub txt1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txt1.KeyPress
RestrictToNumeric()
End Sub

[code].....

The problem I am encountering is that the variable 'e' is used before it has been assigned a value, causing a null reference at runtime.

So I tried to add Dim e As System.Windows.Forms.KeyPressEventArgs As?to the RestrictToNumeric sub.I cannot figure out what I need to "Dim" it as...

Handle Events And Notifications From Multiple Sources To A Main Form In .net?

Sep 23, 2011

I have a vb.net application in which there is a main form. There are around 10 classes each having their own functionalities like tcpactions, fileactions, serialport actions etc. The user interacts with the main form and does certain actions which will invoke the methods in these classes. Now I have a notifications textarea in the mainform and i want to show the current action being performed in those classes and their results in the notifications area.

for example when a user clicks a "Start Process" Button in the form i invoke the method "launchprocess" in a class "ProcessActions". Now this method tries to launch about 7 different process and after launching it sends notification such as "process 1 launched" or if it fails it sends notifications such as "process 1 launch failed".

I currently use event handlers and use them to show notifications but with the amount of events i have to handle it is getting cumbersome and i might have to add even more classes in the future. So is there a better way of handling notifications from other classes.

One Routine To Handle Multiple Events In Arraylist Class Object

Oct 17, 2011

I want to use One routine to handle multiple events & i want to give the list class object to the routine handle clause in vb.net. Is it possible? I have 100 buttons on my web page & i want to handle click event of each button. I have same coding on each button but the only difference is that, which button is calling the event handling routine. So i want to make one sub routine for handling event of all my buttons.

I can solve this by writing each button name in the handles clause like - Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ImgRCP_26.Click, ImgRCP_27.Click,. But it is so lengthy procedure. So that why i want to handle my button in the arraylist. How to do this?

VS 2010 : One Class To Handle Multiple Dynamic User Controls?

Apr 3, 2012

I have multiple user controls (the same one dynamically added to a form 4 times), and one class. I would like all of the user controls raise events in that one class. For example, if any of the user controls are clicked, I want it to send a string to the class to be processed and show a MsgBox "Control name was clicked"I am doing this as an exercise to reduce repeating the same code over and over directly in the control, and to avoid creating the class over and over to accompany each user control.

I don't know how to make use of that.

Tool Tips Or MouseHover For Control Array?

I have a project with Control arrays that include over 200 controls.

I could use Tipster to define a Tool Tip or I could assign a Handler for the MouseHover event & use the handler to provide a help remark.

However, this code is not accepted:

The same for Y. I tested when I commented the Label line out, whether this routine is executd when moving the mouse into "biedkrt" which is the case.
