Button Click Event And Current Thread?
Jan 18, 2012
I have a processing in a do loop. In variois points within the loop I check if the variable "bCancel" is true. If so then I exit the loop and terminate the treatment. When I click the "Cancel" button, I set the variable "bCancel" to true. Basic stuff, but I would like to know how the click event is ran while my current thread is busy looping? I've found a reference to a "Gui thread" on the net but Its not very clear is this thread in inside windows or the .NET frameworks?

I have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

I want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.

Can i Know how to catch between these 2 event, Leave and Click?
I have one checking in a textbox Leave event. I will go check whether this ID is already exist in DB or not. If exist, I will prompt MSG box to user.
When I click on Close button while focus is on textbox, this textbox Leave Event will trigger first before Button Click event.
So, the form remains open without trigger Button Click event.
how to prevent this textbox leave event or how can i catch/control this situation?

I am trying to code for is as follows: Construct a two dimensional array and enter into it a sales id number followed by twelve variables which represent sales totals made by the sales agent. this must provide space for five agents. I can declare the proper array and have done so as follows
Dim Sales (4,12) As Double. I also crafted a click event which will count from 1-12 (which excludes the sales id number) and disables the sales id number so it cannot get used. [Code]
What I am trying to do is setup a function within the same click event procedure which stores the current SalesAmount as a variable in the array and moves to the next slot to get ready to store the next SalesAmount. However I have no idea where to go from here. I have tried a ton of different pieces of code which are either all littered with errors or do not return a value when I call it. Calling the total of each row and the total for all rows is something I need to do for display and I am not one hundred percent sure I know how to do that either.

I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.

I'm getting the following error:"Current thread must be set to single thread apartment sta mode before ole calls can be made"
I am using Speech.Recognition.SpeechRecognizer and using it to open various dialog boxes. It works fine for the first few but on the third one when it calls the InitializeComponent in the Dialog's New, it throws the above error.
Anybody have any clue what causes this or how to fix it? The SpeechRecognizer seems to run on its own thread, so that seems to be at the root of the problem. If I open thedialog with a button click I don't get an error.

I have a silverlight page with a textblock and button on it. Like this:
<TextBlock x:Name="txbNote" Margin="50,50" Text="Hello"/>
<Button x:Name="btnCheck" Height="40" Click="btnCheck_Click" ClickMode="Press" Margin="50,50,50,50" Content="Check Service"/>
Here is the handler for the click event:
Private Sub btnCheck_Click(ByVal sender As Object, ByVal e As EventArgs) 'Handles btnCheck.Click
txbNote.Text = "I Was Clicked"
End Sub
[Code]...
The only change is the relative position of the textblock and button. The button's click event (and every other event I tried) just doesn't fire unless the textblock is before the button in the xaml.

Im trying to create a webform that is a representation of a paper questionnaire that has 14 questions with yes/no answers. If an answer is no, then you must provide information as to why in 3 separate textboxes and store the information only when a user clicks no.I also have 4 drop down lists that are chosen before the user answers the first question that also need to be stored with the textboxes, but the ddl's value does not change after the user starts. Right now I have 3 textboxes and a submit button for each of the 14 questions that are hidden until a user hits a "no" button, in which I change the visible property of all of them and the user then types in their reasons and submits the answer. I am currently doing this for each question and i hide/disable the textboxes and button after submitted.
My problem is that for each event on the 14 submit button's is that I'm forced to open & close an sql connection and insert the values. I know there has to be a way to simply this some so that I dont have 14 different groups of the same code. I would also like a way to eliminate having 40 textboxes on a page lol, because the idea was to have a pop up box or something open that would let the user submit it and then return to the question instead of hiding textboxes, but the user has to see all 14 questions at page load so if you got an answer to that one then that might solve my original question.
