I have the following code, and I want it to act as a stopwatch.
Dim spn As New TimeSpan(0, 0, 0)
Private Sub elapsedtime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles elapsedtime.Tick
spn = spn.Add(New TimeSpan(0, 0, 1))
Label6.Text = String.Format("{1}:{2}", spn.Hours, spn.Minutes, spn.Seconds)
End Sub
However, when the "stopwatch" ticks, the time is shown like this - 0:3, 2:9, etc. How can I change it so that when the seconds are in the single digits, it shows the time like a normal clock (4:05, 2:09, etc.)?
I am using VS 2005 pro and VB.NET. How do you format the DataGridView.DefaultCellStyle.format property for zip codes and phone numbers. I have a zip code and phone number column(s) that I want to be formatted. I have tried a lot of different things:
Zip code: "99999-0000" or "Phone Number: "(999)000-0000" or "(000)000-0000" and the like So far nothing has worked. I can get my date columns formatted correctly, but not these. Can any one give me some examples that work?

I have a requirement that regardless of the start and dates that I need to loop through that timespan and calculate figures at the month level. I cannot seem to figure it out, and maybe it is not possible, but I would like to do something like:
FOREACH Month As TimeSpan in ContractRange.Months Do Calculations (Month.Start, Month.End) NEXT
Is this possible or do I need to calculate the number of months, and just iterate through the amount of months and calculate the start/end of that month based on my index?
I am throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.
Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11
Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM
For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation
BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.
I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.
I have created a class from an xml schema (that I do not own and cannot change) using xsd.exe. Using this class, I am deserializing to bring the data in to an object collection to consume. There are times when I want to take objects in memory and pass them to the class created by xsd.exe using a constructor I built to generate a serialiable object collection.
I cannot figure out how to format some objects correctly Example: In the xml file, there are certain simple types that are floats that come in with 6 digits of precision. When I write them out, they have 7 digits of precision. Anorther example is integers with leading zeros in the xml file. They come in as 4 digits regardless of leading zeros, but I can't find a suitable way using serialization to output them (other than to change the property to a string datatype.[code]...

I have a project with about 20 forms and each form have an average of 10 buttons. Today my boss woke up with the idea of changing the appearance of the buttons adding a background image to them. Is there any way to apply this change to any button in the project without making the change one by one? Creating a custom control is not the solution because is even more complicated at this point.
