when clicking on the start button in the code below, the form seems to lose focus and I need to click the stop button twice to stop the count. (First click to activate the form, second to click the button) Can someone please explain this behavior or offer a better alternative?

I have a form which contains a progressbar and a Listbox which update as the code runs through and performs some sometimes time-consuming calculations.
At one point in the code, it breaks to ask the user to enter a number using :
Usedefault = MsgBox("Do you want to use the default value of " & Default_No & "?", vbYesNo)
If Usedefault = vbNo Then
[Code].....
this works fine but I find that once the data entry is complete, and the code continues to run, the form loses focus and the progressbar and the Listbox updates cannot be seen until the code finished its calculations.
I have my form set up to be able to be kept on top if the user so chooses. When it is set to be kept on top, I want the opacity to be reduced when the form loses focus. When I set opacity on init, it works fine. When I use this code, it doesn't work:
Private Sub Form1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.LostFocus
Me.Opacity = 0.2
End Sub

Maybe I misunderstand how LostFocus and GotFocus work, but according to MSDN this appeared to be what I wanted.
I have a question regarding waiting for closing a window or changing focus back to my app. What i have is an app that creates a few tables, that then puts the tables into a temp file that wordpad opens for the user to check they are correct, this is where i need help, i would like to now wordpad is open wait until the user closes wordpad or changes the focus away from wordpad until i open the next form which is responsible for using the tables and converting them into xml.
Which event should i look at using that fires when a program is exited or gets focus?
Most of my experience in Visual Basic programming is in VBA. I'm currently trying to build a VB.NET Windows application that basically consists of a form that has one button and one label. When the button is clicked, the label should serve as a "counter" that counts from 0 to infinity until the user closes the window with the "x" button. I do this by putting a loop with a sleep statement in the onclick sub. The loop iterates the integer that is displayed in the label and does a "Me.Refresh".The problem is when the window loses focus. When it loses focus (when I click off of it), the counter stops. Even when I click back on it, the counter doesn't resume.

View 2 RepliesI have two mdi children forms open. I would think that clicking on the non active form would change the focus from the active form to the form I just clicked on. It only does this if I click on the title bar. Then the focus changes. But if I click on a control on the non-active form, focus does not transfer.
View 5 RepliesI have a form with a "print" toolstrip button. When I click that button I run the code shown below. The print dialog box appears. The title is dark blue seeming to indicate it has focus. The main form is lighter blue indicating it does not have focus. But hovering over the "Print" button (or the cancel button) does not cause it to change color. If you click on the print button, then the color changes and the second click causes the appropriate action. Same with the cancel button. If you click on the dialog label or on the main form the only thing that happens is the print button will then become "active" and a click there then works. If you click on the main form once, nothing happens, but if you click on it a second time you get the "bonk" sound indicating you ae clicking on the wron modal. As if this isn't strange enough, this action just started recently. I made a few unrelated (as far as I can tell) changes, and discovered this action.[code]....

View 6 RepliesI have a form with multiple datagridviews. On save the entire dataset will be serialized to a strongly typed property bound to a sql varbinary(max) Works fine. Of course the current "dirty" cell will not be saved as mentioned here :
[URL]
My problem is the user could be coming from any one of 20 datagridviews when they click SAVE. Is there any way, short of checking for a dirty cell in each datagridview to commit any dirty cell before the save ( clicking another textbox control before the save does the trick but calling the focus() of that textbox prior to the save does not ) I was thinking perhaps catching the event of leaving the grid but it seems the base problem is clicking a button (for reasons I think I understand) does not fire lostfocus events for the current control and it doesn't seem the click handler args knows what the last current selected control is.
When the user clicks the Exit button it closes the forms and if there was an open file it asks the user is they would like to save. But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes. How do I write the close for Exit to take into account how the [X] works and close the application cleanly?

I am developing windows application. I have datagridview in that, I have one column as DatagridviewcheckboxColumnand i have on button on my form.
If i make checkbox checked and press button, it loses checked and becomes clear(unchecked). what is the problem on button click i have done iterate loop to get checked box checked buti can not get as i told that, on button click it becomes clear(uncheckeD)
Is there any way to determine whether a form was closed by clicking the "X" button or by calling Me.close? They both fire the FormClosing event, but I need to determine how the form is being closed so I can do different things.
View 7 RepliesI 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.
View 12 RepliesI have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.
