How do I change a date such as "2/9/2011" to "20110902" [ie] to yyyymmdd ? At first I thought I could simply use the substring function but I don't know how to add the zeros for the month and day when necessary.

How do I convert it back to the date?
conversion of date
if i used -- Date.parse("28/01/2011")
it gives me error as "String was not recognized as a valid DateTime."
so then i modify above code as -- CDate("28/01/2011").it gives me error as "Cast from string "28/01/2011" to type 'Date' is not valid." I used convert.todatetime also date.parseexact but nothing is working..
For some reason vb keeps changing my dates format and removes the 0s at first this wasnt a problem but it really messes up my sorting in my gridview.

We are running .NET 2.0 ASMX web services on Windows 2003 server on IIS 6.0. We have migrated a legacy VB 6.0 application to .NET 2.0 application using VB.NET. CDATE function is used at many places and we did not replace that with .NET equivalent date functions. After migration, code was working fine for many years.Recently, we have started encountering issues on our production servers where the below code fails:
CDATE("11 Jul 2011 21:10:27")
Error: Conversion from string "11 Jul 2011 21:10:27" to type 'Date' is not valid."If we perform an iisreset, the same code starts working fine. Could this be due to some recent patch for Windows server/ .NET patch?

I have a calendar column which is generated on from load. Its value is assigned to todays date - for instance 04/04/2012

Is there a way I can change the value of my calendar column to reflect the chosen month?
For example, if I select January from my comboBox then have the date as 01/01/2012.[code]...
It is supposed to change the forecolor if the listview date in the first column is less than label 3's date.

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.

View 2 RepliesSo I have a Powerpoint presentation. It contains numerous images on it, referred to by image X. (So it's the same image but on multiple pages) These same images on different pages/slides have different width/height attributes associated to them. So even though they're the same image, they may not be the same size.
So there exists a scenario where an image exists on a lot of the slides. I want the ability to replace all of them at the same time (quickly) without having to go through each slide and separately replacing X, one at a time with the new image.
Is this possible? (yes/no)How would this be accomplished? (abstract - high level explanation is only required)
