VB.Net (2008) doesn't seem to allow inserting formating characters (eg.) in String.Format:
'BAD MessageBox.Show(String.Format("{0}{tab}{1}", "Foo", "Bar"))
'BAD MessageBox.Show(String.Format("{0} {1}", "Foo", "Bar"))
MessageBox.Show(String.Format("{0}" & vbTab & "{1}", "Foo", "Bar"))
Is there an easier way to build a formated string that must contain formating characters?
I need to format a string in a fixed number of characters.
For example, if someone type TWO
It has too save in the variable
000TWO
if type THREE
0THREE
Always 6 characters and fill the rest with zeros on the left.
For years I never had trouble with this String. Format function until today when I got a value longer than 0 characters and the function returned all the characters in the string instead of just ten. Now sometimes I get less than ten characters so I can't use the substring with out getting an error. I can try the left function but I was hoping there was a solution with the Format function.
View 6 RepliesHow can I insert a hyphen after each 3 characters in a textbox? For example, if in the text box there are: ABCDEFGHIJKLMNOP. how can I insert a hyphen between each 3 letters automatically? The result would then be ABC-DEF-GHI-JKL-MNO-P. I have come to a way but it's not a practical one, i.e I used Insert(,"-") but then lines are filled with conditions slowing down the application. [Code]

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?

View 3 RepliesI need to create a console program that allows you to enter a string, of which is then outputted in reverse.
Sample:
Input: Diewas
Output: saweiD
Apparently I need to find out about strings and will also need to use a loop.
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

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 have written a program that uses an array of the english alphabet and Morse code. I also built a form with a input box for the alphabetic information and an output box with the Morse Code. What i am trying to do is basically type a word like "Hi" in the input box and produce the Morse Code equivalent in the Morse Code output box. [Code] This works but only one letter at a time. Do i need to Parse the string of characters one at a time, and then run it through a loop like i have created?
