Multiple Textboxes Calculate On Lost Focus?
Jun 9, 2011
I am trying to get my little program to do some calculations.So far i got 15 textboxes, named TxtPP(followed by product type),so i got TxtPPproduct1, TxtPPproduct2 etc..At the bottom of the form i got a disabled textbox which shows the total of all the above textboxes.Now i don't want to use a button to click when doing the calculations.I want this to be done every time a value is added to one of the textboxes(so on lost focus).

Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!
So for example something like this...
Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

I have a form with 7 textboxes, all describing different attributes of a used car. In the shared leave event of my tb's, I need to code a case statement which determines the particular textbox that lost focus. I then need to perform different tasks which I understand how to do, and I don't think they matter to my question.
I understand how to give focus (txtTextBox.focus()), but how do you tell if something has lost focus?
And furthermore, how would you use that to structure the case statement?

I had previously made a simple Pong program which use keyboard to control. The control includes "s" to start the game, "p" to pause, "r" to resume and left, right to move the paddle specifically. This program work with little problem. The first problem I encounter is if I insert even one single button on the form to display instruction, the arrow keys will no longer work. But I get around it by using Menu Strip instead.
Then, I am required to put this program, among others into a MDI program. And this is where the problem happen. If I have this Pong game loaded, and I press "s", "p", or "r" keys, it have no problem, but if I press the "left" or "right" keys, it will not move. I am speculating that maybe the focus is lost when arrow keys is pressed or something similar, but I have absolutely no idea what is happening. I have tried giving focus back to the form if focus is lost, but to no avails. And this is the code for the movement of the paddle. This reside on a form, the movement itself is passed to another class. The MDI parent is on another form. [Code]

I am using VB.NET to build my application. And in my application has a lot of Forms. It doesn't use MDI Parent Form, but I use another simple Window Form (I named it frmMain) that I suppose it is my MDI Parent Form. When frmMain load, windowState = Maximized. And when I open a Form (example: I named it frmCustomer) that I suppose it is my child Form, and I set its properties (frmCustomer.TopMost=True) when it load, so it always on the top. But When I change to open another application such as Ms. Word or Mozilla Firefox... the frmCustomer is still on the top. how can I know my frmMain lost focus?

I have a datagridview with a combobox column. The combobox column is populated from a collection. I begin to add data to the dgv, I select in the first row a value in the combobox and go to the second row. In the second row, when the combobox gets the focus, it appears 'V18', also the selected value before. Why? An on the other, when the combobox in the second row losts the focus, the combobox value is nothing. Why? Here are two images:

I have an application I run on a netbook that is folded up inside a robot.Occasionally, something from the system tray will pop up unexpectedly. This removes the focus from my application I also thought there was a way (in forms properties in the vb6 days) that would allow to "run when minimized"? In short, I want this application to be running and nothing (asides an application error message) else getting in the way.

My application has a form which contains several Textboxes where user is required to fill up data. Once data is filled up user can click on "Save" button to save the data. I have added lost focus events to all textboxes so as to validate user input. When I click on cancel button, i want to detect cancel button click, but textbox lost focus is fired first so I get error message for textbox before my code moves to cancel button click handler. Is there any way to detect button click before lost focus event?

I have a small doubt: (VB.Net 2005, MS-Access 2007)Is it possible to add the current row from DGV to DB as soon as the row lost its focus..i.e. whenever i add a new row in DataGridView it should automatically get inserted into the database without pressing any buttons... Bcoz i need to add more new rows dynamically & hence i find little difficult in clicking the ADD button again and again to insert each and every Record.

I have created an app which has a timer control which, when activated and meets a certain criteria, launches a second form with an alert for the user to review and action. this works just fine. Except.... when the main app is minimised and has lost focus, instead of launching the second form to a normal windows state it opens and sits in a minimized state itself and just flashes. How can I get the the second form to restore to a normal windows state?I have tried form2.focus and tried the windowsstate=normal etc but I'm still barking up the wrong tree.

I have a datagridview(dgv) with a DataGridViewComboBoxColumn(colLocation)
colLocation.AutoComplete = False
colLocation.HeaderText = "Stored to"
colLocation.DataSource = DB.getLocation()
[code]....
I added the colLocation to dgv."descirption" contains Unicode characters. I can see the comboBox correctly and choose the item.The problem is when the comboBox lost the focus, the value is changed to first item of the comboBox.
Updated:I found out that the ComboBox doesn't change the data when the DisplayMember is in English characters. It changes only when the DisplayMember is in Unicode chracter.

"Form1" has a ToolStripContainer1.TopToolStripPanel which contains a ToolStrip with buttons. The buttons work on ONE click when "Form1" is active.If I click on another window and then return to "Form1" the ToolStrip buttons take TWO clicks to activate.The first click returns focus to "Form1" and the subsequent click fires the button event.I want the buttons to work on the first click and not require two clicks.Note that ordinary buttons on "Form1" that are not part of the ToolStrip work on the first click when returning from another window/form?

I have a Visual Basic Program that, when I enter data into a textbox, uses LEAVE events to update it. However, it will not update until I go to another textbox or press a button or other similar control.This also happens when using the LOST FOCUS event.How can I make the textbox update (be it doing a financial recalculation or some other custom function) happen when the user clicks/tabs out of the textbox and NOT having to click on a button or into another textbox?Do you recommend having a separate button for performing the custom functions?

Combo box 2 is filled based on a selection made in combo box 1 and a listview is populated based on the selection made in combo box 2.When the LostFocus event completes in combo box 1, it hits the LostFocus event in Combo Box 2 but it shouldn't. How do I prevent this from happening or if I can't prevent it, how do I work around it? The following is the code used.
Private Sub cboCategory_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboCategory.LostFocus

Ok I need to have a message box pop up when a user clicks the "Add Patient" button and the message box should have multiple textboxes which include Patient name, Patient ID, etc. I guess my question is can I do this with a message box or do I need a new form to pop up when the button is clicked. The form is connected to a database and the info entered should be added to the "Patients" data table.
