Save On Form Losing Focus?
Nov 30, 2009
I have three forms frmStudent, frmClass and frmMain. I want to add code so that if the user focuses on another form without saving a message box will appear to prompt the user to save. This is necessary because If the user starts entering data on another, related formand assumes that the changes from the first form were saved, then there could be integrity issues.
I have tried formating the deactivate event, but when I hit yes it just deletes the record entered.
Private Sub frmStudent_Deactivate(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Deactivate
If GradebookDataSet.HasChanges Then

I 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.

I've created a small form that acts like the office notifications (fades inout above the notification icon tray)I'm having problems showing this form, I want to display it without the focus being taken from my main application (or any other form), I've managed to get the attached code doing roughly this, (using Me.Activate to take back focus) But this isn't great - focus switches for an instant plus I want to show the form from various areas in my application...
Dim frm2 As New frmNotification()
frm2.TopMost = True
frm2.Show()
Me.Activate()

Is is possible to prevent a modeless form from losing its focus? I would like to force users to click the exit button of an addin form shown modeless before they wander into the main application. I need to show an user form of an addin modeless, in order to be able to interact with the document of main application. However, I would like to force them to exit this form before going into the main application.

I want to prevent my application from losing focus, untill I close it. (so that I can not click on ANYTHING else, untill I'm done with it. period.)I've tried using Me.Focus() on a timer, but that doesn't do s***...I've also tried countless API's out there, but I seriously can't get any of them to work.. my form simply does NOT want to stay in focus! It's driving me crazy! What the hell am I doing wrong?

I've written a short application that consists of a form, listviewbox and a timer, the program sits in the taskbar with the form invisible, the timer is set for 40 seconds and basically it queries a database held on an SQL 2000 server, when a certain change happens within the database my form pops up and shows some data in the listview, this happens well, the problem I have is when the check is going on (every 40 seconds) the user loses focus on what ever they're working on. Is there a way I can stop this?

I need to start multiple processes, with minimized windows - and I don't want whatever the current process is to lose focus.Something like this should be simple enough:
[Code]...
However, whatever application is running will lose focus when this code is executed. I've looked high and low, and there doesn't seem to be any relatively simple way to do this. I had some ideas about capturing whatever application has focus (I don't want to assume my program has focus), then running the above code, and then restoring focus. However, I'm fairly certain this will require win32 API calls, and I'm not sure how to do that.

code...
Dim sqlConn As New SqlConnection("server=.SQLEXPRESS;Integrated Security=true; Database=memberlist;")
sqlConn.Open()
Dim sqlComm As New SqlCommand("SELECT * FROM memberlist", sqlConn)
[code]....
when i do this the first msgbox pops up, i click ok, it then loses focus, i think its actually minimizing. I then have to click it in the task bar several times to get it to come back up. from then it will sometimes give each msgbox over and over just fine, sometimes it will minimizes random ones. the first one seems to be a constant.

I have 2 window forms, form1 has a button, which will send a msgbox when I click on, and form2 closes when it's deactivate-event raised. If I have form2 focused, and I click on the button of the form1, form2 will get focus and then close, but no msgbox showed from form1, what should I do to get the msgbox in that case?

I'm creating some software to keep my students on task. I've set it up so that I can control certain aspects of their computer from my computer. Problem is, I'm not sure how to control other applications from my application. I mostly just want to prevent it from being minimized. Some students like to switch screens quickly when I walk by. I would just like to make sure that it is always on top until I specify otherwise. I'm using VB.net, I'm using the 3.5 .net framework for compatibility reasons.

In VB .Net 3.5, is it possible to change the color of a DataGridViewCell (unbound) to a different color and have the cell visibly change before losing focus or leaving the cell? I have a timer that's running that queries with the data present and I'd like for the colors to change immediately instead of after the user leaves the cell.
I've tried DataGridView.Refresh and Me.Refresh and don't get results.
What am I doing wrong? (Below is the code I use to change the background)
''' <summary>
''' Sets or clears the passed cells background to Red
''' </summary>

On a .Net app, I got an AxDataGrid on a form. The DataSource of the grid is a RecordSet,created by parsing a comma-delimited text file.rom the UI, I add a new column with a defined size to the text file and then reload the data grid with a routine that creates a new ResultSet and binds it to the grid. Things are fine and the new column is shown.

Having some issues with creating a simple control in vb.net.
I create a control with a single label in, I don't change anything except the colour of the control and the label and also making the label anchor to the edges ( with a small border around the edge)
When i then build it and add this control to a form. Some of the edges are cut off and it isn't anchored the way it was in the control.[url]...
as you can see in the second image the control has lost its white border at the right and bottom.

I need to save the form settings, like a save state of the form. Because the program allows the user to add controls. I would like to be able to save them and load them. BTW: The controls are Panels and Labels. BUT! The Panels are a modified version of the control, known as NewComp. This simply allows the user to drag the panel around the form.

I have a form where in it there's a webbrowser control doing some autonomous tasks. I leave it running in the background but, due to the navigation in the webbrower control, the window pops-up in front of all others and this is really annoying when Im doing something else.
Is there a way to disable the form from auto-focus or whats doing? Even if I hide the form using Hide() it still is able to remove the focus from whatever window has it.

I'm working on a program to wish my girlfriend a happy birthday, my idea is to show a label like a notification, similar to the one used in messenger, but I want it to be on top of whatever she is working on the computer at the time, even games (she's a hardcore gamer). Is this possible??what I'm asking for is a form on top of everything, not stealing focus, and if she presses a key, for example "q", the message activates no matter what she is doing. I'm a beginner, and I know how to do the label, the key press, but I don't know how to do the above mentioned

I want to create a program that gets if the user has pressed a code, for example F8, but without the user having to have focus on the form. I want the program to start hidden, and while the user works normally (say browses the internet (Go Google Chrome)), he just presses F8 and the form shows up. So I ask, is there any way to get key presses outside the form? [code]

Whenever you have a messagebox, it grabs attention from your main window and doesn't let you click back into your form until you hit okay.I want to make a form that does kind of the same thing. I have this for that shows download progress and I don't want the user to be able to click back into the main form until the download form is finished.
