Removing Leading Zeroes From A Textfield When It Loses Focus
Feb 27, 2012
I'm trying to have a Textfield lose it's leading zeroes when the user leaves the field. I made the following "Leave" event but it's not working. It works for the first half however to set it back to 1 if it's blank or if a user entered 0. I tried following the advice on this answer, but it didn't work:
I am writing out a CSV file in a VB.NET Windows Application. It is a string, like this:99,Company,00666,TBDOn another form, the user can browse to this file and open it.When he does, I use the Microsoft Jet OleDB provider and read this file into a datagridview. It displays the four columns in the grid, but it truncates the two leading zeroes on 00666 and displays 666.I need those leading zeroes. I tried writing out the string like this:99,Company,'00666,TBD(notice the leading single quote before 00666, like you would type in an Excel cell to indicate it was text), but then when the four columns are displayed in the grid, I have the single quote and the two leading zeroes. I don't want the single quote, I just thought I could use it to indicate text.So my question is how can I write out a string of leading zeroes and have them read into the grid preserved?
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 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]....
I have a listbox on a form and when the user selects a value and the listbox loses focus I want to validate the value the user chose. How do I call my function once the listbox loses focus?
I tried using a custom validator but it gives me an object is missing error. Mike
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 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
[code]....
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?
Is there anyway to detect if the vb app I am developing loses focus, ie, if a user switches to another task. Maybe is there a way to detect which process in windows is active ?
Is there any way to remove the focus from the current cell after edit when I click the row header? I have tried various methods; repainting the row, cell, moving focus to other cell but the caret still remains in that cell.
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.
synchronizing a combobox with a textfield. I have a form with a textfield and a combobox. The combobox is populated with the department name from the database when the form loads. I would like the textbox to display the corresponding department number when the user selects a department name from the combobox. I have tried using the SelectedIndexChanged event of the combobox but I can't seem to code it to work. This is the code I'm trying to use but it is displaying "DEPARTMENT" in the textbox. Department Code is the primary key of the table.
strSQL = "SELECT * FROM DEPARTMENT" Dim da = New OracleDataAdapter(strSQL, cn) da.Fill(dSet, "DEPARTMENT" )
my problem is I dont know what string i have to add here for the backspace. this is the line of the problem:

(I use VB 2008) I'm working with the webbrowser-component. I got a problem to fill a text-field. The textfield is named "description" but I cant fill it. I guess it's because it's more than one form on the page that got a element named "description".
