Forms :: Base Window Events Are Triggered When Focus Is On Another Form On Its Top?

Apr 3, 2009

I am migrating my code from vb.net 1.1 framework to vb.net 3.5In my windows application, the base window has some buttons and events are written for the same.I have shortcuts defined for these buttons also, for example: ctrl+d, DEL (keyboard) etc.Now i open a property Grid form on top of my base window for a selected object.Even when the focus is on this property grid, i am noticing that my base window events are firing on pressing those shortcuts.

example:I select some text in my property grid and hit delete button from keyboard. The delete event that i have written for the selected object gets fired and the text is not deleting.I fail to understand why is it happening. It wasnt behaving like this in .net 1.1.In .net 1.1 it would delete the text and only when the focus is back on the base window, hitting Delete would call the event.How do i control such a behavior? Is there some property that i need to set for property grid in .net 3.5 to prevent base window events from firing till the time focus is on property grid form?

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?

Forms :: Use The Focus Events Of The Combobox's To Determine?

Jan 7, 2010

I have two questions for anyone who can throw some idea's my way question 1:I am currently working on a control with three combo box's. This control will be nested on a form, and I want the on-board timer to track how long each control is active. I am trying to use the focus events of the combobox's to determine if the control is active so the program will know when the timer should be started and stopped. My problem is, for example, when the user causes the text property of the combo boxes to change, the folowing code runs:

[Code]...

As you can see, there are points in this sub-routine that can cause the focus to shift, as well as fire the text changed event. While this all happens faster than is really noticable, I would like to eliminate the extra cycles if at all possible. As I mentioned in question one, I am adding this control to a form, to be more clear I am adding multiple instances of this control to a single form, and I am trying to use the focus events to determine which of the controls within the form are active; however, when the form itself is no longer the active application, whether it is minimized, behind another application or otherwise, all of the timers stop. I want whichever control was active at the time that the form was deactivated, to continue as if nothing changed.

Fire The Timer Or Other Routine While Still The WHILE TRUE Routine Checks For Incoming Connections And Messages?

Jan 24, 2012

I am using sockets to send message between computers. I send the messages alright. What I want is when the message "x0x" comes, the client must be closed within 5 minutes. Teh admin can cancel the request by sending message "-xx" as well. The routine that checks for incoming connections and accepts messages uses WHILE TRUE...END WHILE since it must always listen. Once I get a message, I need to fire a timer control or other that fires within 5 minutes. But the program cant leave the WHILE TRUE at all. If i exit it early, the timer fires and the program does get exit. How do I fire the timer or other routine while still the WHILE TRUE routine checks for incomin connections and messages?

Reference A Particular Code Routine In .net External To The Current Loop/routine?

Apr 17, 2011

is there any way to reference a particular code routine in VB.net external to the current loop/routine?Example:

If Var01 < 5
[Routine A]
Else
[Routine B]
End If

where Routine A and Routine B are code sequences at the end of the entire program -- such as outside of the current sub or class? The idea would be to reference an otherwise repetitive code.

Asp.net - Share A Variable From Sub Routine To Sub Routine?

Mar 3, 2009

I have a sub routine where I pull in information from a database. I want to use variables from this sub routine in another sub routine. I tried making everything public but it doesn't want to be friendly and share.

Dim strEmail as String
Public Sub readDB()
strEmail = "whatever@doohikcy.com"

[Code]....

The readDB would read the database and set the variables and do whatever it needs to do. Then when they submit the form it would e-mail the form to whatever the email address was.

AfterRowUpdate Event Is Not Getting Triggered?

Sep 28, 2009

I am using VS 2008 and UltraGrid from Infragistics v 5.2

I have two UltraGrid objects on a Winform. While the AfterRowUpdate event gets triggered for one, it does not get triggered for the other. Here's the procedure of the offending UltraGrid event:

This does get executed:

Private Sub ugPatient_AfterRowInsert(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.RowEventArgs) Handles ugPatient.AfterRowInsert
e.Row.Cells("Courtesy_C").Value = "Mr."

[Code]....

The source file is different from when the module was built. Would you like the debugger to use it anyway?

Even if I rebuild by application, the dialog box does not go away.

Find Out What Triggered An Event

Jul 30, 2011

I'm having a really annoying issue which I can't get to the bottom of. I've got a NumberUpDown control which has a ValueChanged event. There is only one reference to it in my entire project which I have commented out to prove that it isn't calling the event. Even though the number is not being changed (the control sometimes isn't even in focus!) the ValueChanged event gets called. This is driving me crazy and I wondered if I could back track through the code to see what actually caused this event to trigger?

Alert Triggered Based On Parameter ?

Oct 15, 2011

My problem is, I have set the parameter to be 150 in the database. and the alert triggered should refer to the parameter value. if the calculation result exceeds the parameter value, it will turn the box to red colour. however, i notice that it only compares the first three number. for example, if the calculation result is 1778.99 it will turn the box red because its first three digit is more than 150. but if the calculation result is 10234.90, it does not trigger the alert. i assume it only takes the first three digit.

Here is the code for this part;

Dim total1 As Label = CType(e.Item.FindControl("total1"), Label)
total1.Text = e.Item.DataItem("inventories").ToString * 365 / e.Item.DataItem("operating_cost").ToString

Validating Event Getting Triggered Twice In Maskedtextbox?

Aug 17, 2010

I am facing a issue while using the "validating" event of the maskedtextbox. I have an MDI form, in which there is a main form and a form acting as bottom bar. The bottom bar comprises of buttons for moving to "previous" and "next" forms. If suppose in the main form i have a maskedtextbox and the initial focus is set on it, then on the click event of the button (next; which is on the bottom bar form), it calls the validating event of the maskedtextbox twice. In the validating event of the maskedtextbox, i am checking some validations and if it doesnt pass, then i set [e.cancel = true]. just let me know the reason behind the triggering of "Validating" event twice?

Textbox_Leave Event When Triggered By Selecting Different Tab In Containing Tab Contol?

Aug 12, 2010

I have a textbox in a tab control and iv'e coded the textbox_leave event to show a msgbox and reselect the textbox if the text doesn't meet certain conditions.

Private Sub TextBoxChaseTime_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBoxChaseTime.Leave
If IsDate(Me.TextBoxChaseTime.Text) Then
Me.TextBoxChaseTime.Text = Format(CDate(Me.TextBoxChaseTime.Text), "hh:mm")[code].....
(Reselecting the textbox is the only way i can find to efectively cancel the leave event - is there another)

I've also added a line to also reselect the tabpage incase the textbox_leave event was triggered by selecting a different tab in the tabcontol.However, when the textbox_leave event is triggered by the user selecting a different tab the textbox_leave event seems to be triggered several times displaying the msgbox four times.why this is, but it seems to be caused by the by the line that reselects the tabcontrolhow to stop the msgbox being shown more than once Interestingly, if i add a line to change the text in the text box to meet the conditions the msgbox is only shown once, but the tabpage is not reselcted

Asp.net Mvc - Post Code Being Triggered On JQuery Load?

Jan 13, 2010

I have the following functions in my ProceduresControlller:

Function Add(ByVal bpid As Integer) As ActionResult
Return View(GetAvailableProcedures(bpid))
End Function[code].....

I'm loading the Add dialog via jQuery like so:

$("#dialog").load(
"/Procedures/Add",
{ bpid: 123 }[code]....

This is failing because it's calling the Post method (where "covered" can't be empty) instead of the Get. I tried decorating the Get with <AcceptVerbs(HttpVerbs.Get)>, but it doesn't change the outcome.how do I get it to use the Get? I realize I could change the names to not be ambiguous, but I want to know why it won't pick the Get if I'm only passing "bpid".

SelectionChange Event Not Triggered When Form Minimized

Mar 25, 2011

I have an application with a DataGridView and WebBrowser controls. In the DataGridView I load a DataTable using BindingSource. DataTable is just a list of URLs. I use SelectionChanged event on the DataGridView to load a selected URL in the WebBrowser control. The problem I have is that when I minimize form to the tray, it for some reason triggers SelectionChange event multiple times. What's really weird is that if I minimize to the taskbar SelectionChange event doesn't get triggered. It also doesn't get triggered if I load URLs directly to the DataGridView. What triggers SelectionChange and how to get rid of it?

Public Class Form1
Dim URLTable As DataTable = New DataTable("URLs")
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim URLColumn As DataColumn = URLTable.Columns.Add("URL", GetType(String))
