I'm pulling from a text box for recording scores like 2, 47080, 88 and for better aesthetic look on viewing results i wanted to format results like so:
00002
47080
00088
Only way i could format was to convert to number and use: Score.ToString("0000#") not worried about validation, this is just something for my rug rats.Is there a better way, as in not having to convert to number first?
I've got a string that looks like this:
00:02:49.5350000
h m s
h=hour
m=minute
s=seconds
I would like to format that string so it looks like this:
2:49
m s
Is there any way i can do this easily?

I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?

Error I keep getting is "Input string was not in a correct format." It is getting this error because of this:

So I need a format string to pass to String.Format that would "move" the decimal point.I can't perform any math operations before doing the String.Format, so it has to work right off the bat.Basically I'm emulating a formatting string from a proprietary server. In it if I say:
"MR2"
for the value:
12345
The result is:
123.45
I'm close with this, but it's not spot on:
String.Format("{0:#0.##}", 12345)
an extra, but not necessary... there is also MR2Z, which moves the decimal 2 left, but if the value is 0 "" is returned.
however, i'm copying this directly from the book in its example format and still getting an error.
FormatException was unhandled
Input String was not in correct format

I need to take a string formatted like '010711' (DDMMYY) and put it into format '01-Jul-11'. Ive thought about doing something like string.toArray and then having some conditionals that format from there but am looking for an easier way.
View 5 RepliesI want to format the Timespan to have format like this 49 hr 34 mn 20 sec
I used the String format below :
String.Format("{0:00}:{1:00}:{2:00}", theTimeSpan.TotalHours, theTimeSpan.Minutes, theTimeSpan.Seconds)
It formats the Timespan to this format 49:34:20. How can I add hr mn sec to the String.Format above? or there's another easy way?

View 4 RepliesI have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?

I want to develop an application using VB.Net to detect the arrival of USB Key once it's plugged into the USB port. I used a method by getting the list of all drives in the computer and then I check whether the type of the drive is "Removable Disk" and "Is ready" or not!. By using this method, I can figure out which drive is Removable drive. BUT I get confused with the FLOPPY Drive because it's also a type of Removable drive.

I am working on a application that stores videos, images and files. I would like to give the user the possibility to encrypt them. I am tying to use AES to encrypt them but the problem is that the decryption takes to long.I was hoping that the loading time from the hard disk of the encrypted file was far longer than the process of decryption of an image for example but i was wrong
So if i try to 1) load the image 2)decrypt it and 3)load it in a image control it takes 15 times more time that loading the original file not encrypted

Im have a form and an image. Imagine the form's backcolor to be black and the image to be a landscape. When you resize the form the image is also resized and streched towars all directions. The point is that as you resize the form the image delays to be resized so the background which is black is showed.
