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:

Read Csv File Into Dgv And Preserve Leading Zeroes.

Oct 7, 2010

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?

Form Loses Focus After A Messagebox?

Feb 13, 2012

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.

Print Dialog Loses Focus

May 4, 2011

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]....

VS 2008 Get The Opacity To Be Reduced When The Form Loses Focus?

Jun 18, 2009

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.

Forms :: "Counter" On Form Quits Counting When Form Loses Focus?

Mar 15, 2009

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.

Compare A Textfield With The Value Of A Datareader?

Aug 1, 2011

This may perhaps be a stupid question but I just can't get it to work.

I have an if clause where I compare a textfield with the value of a datareader.

It looks a little like this if me.txtfield1.text <> reader("field1") OR me.txtfield2.text <> reader("field2") ETC... I do this for a lot of field.

But now I want to check if field2.text is string.empty and if it is I want to skip the comparison for that field.

How To Synchronize Combobox With Textfield

Sep 27, 2009

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.

Dim da = New OracleDataAdapter(strSQL, cn)
da.Fill(dSet, "DEPARTMENT" )
