Replace Doesn't Replace / Formatting A Timespan For Display
Dec 8, 2008
I'm working on a timekeeping application in Visual Basic 2008 and am having trouble formatting a timespan for display. Here's how I want to the information:If a positive number my Label will be: lblTimespan.txt will show as "12 Hours And 15 Minutes" This works fine.If its a negative number I want to display it as "(12 Hours And 15 Minutes)'[ in red. The problem is that I can't get rid of the minus sign. [code] Thr Replace doesn't seem to want to replace the "-", can anyone suggest what to do?

The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
Public
Sub Main()
Dim R1, O1, P1, C1, strDateFrom, strDateTo, strRunDate
As
String

I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString")
Private _myObjectLongName As New ThisObjectLongName("SomeString")

I am trying to think of a regex replace to replace double quotes with nothing. Example:
hello("hi there") would become hello(hi there)
"hi" would become hi
"example "3" would become example "3
-edit Maybe an easier way to explain this is, replace all " that do not have a backslash before them.

I am trying to filter out all unwanted characters from a string. All I want in the string is letters A-Z, numbers 0-9 as well as comma (,) plus (+) and quotes (").I figured how to do the letters and numbers, but the 3 special characters are giving me a problem. I also tried with the Chr(34) equivelant for the " sign, but no luck, as and " or , messes up the way the code is read. Here�s what I have so far, but it only works for A-Z and 0-9:
STR = System.Text.RegularExpressions.Regex.Replace(STR, "[^A-Z, 0-9, Chr(43) ]", "")

How can I specify in my string that I want to replace occurrences of ALL characters and replace them with a specified character? Something like this:
'assuming currentWord is a string that contains any word
_myWord = CurrentWord.Replace("a-z,A-Z", "*")

I am using replace function to replace a character in the file
sw.WriteLine(Regex.Replace(strLine, "\", Chr(13)))
This code is working fine, but now I want to replace two times and I want to use the replace function twice. Something like this, but it is not working . Can anyone tell me how to use Replace function multiple times?
sw.WriteLine(Regex.Replace(strLine, "\", Chr(13)).Replace(strLine, Chr(13), ""))

I'm doing some math with the Timespans in .Net, and occasionally the sum results in a negative Timespan. When I display the result I am having trouble formatting it to include the negative indicator.
Dim ts as New Timespan(-10,0,0)
ts.ToString()
This will display "-10:00:00", which is good but I don't want to show the seconds so tried this.
ts.ToString("hh:mm")
This returns "10:00" and has dropped the "-" from the front which is the crux of the issue. My current solution is this:
If(ts < TimeSpan.Zero, "-", "") & ts.ToString("hh:mm")
but I was hoping to accomplish the same by using only the format string.

A TimeSpan by default shows hours, minutes & seconds when converted to a string. How do I show only hours & minutes? I tried ts.ToString("hh:mm") but that doesn't work.

These two TimeSpan are stored in the Database with 24hr format. No date, only TimeSpan.
Dim r As TimeSpan
Dim tsStart As TimeSpan
Dim tsEnd As TimeSpan
[Code]...
Is there any TimeSpan method to get this right?

The user enters a numerical value in textbox1 and click search. This searches for this value using PackageIO (any other options you guys think would be faster would be great) and will return how many instances of that value have been found. There is a second textbox and button that will only be enabled if 1 instance is found. If more than one instance is found, an error message pops up. I'm not too experienced with PackageIO. Here is what I have so far. The program crashes every single time. I'm positive there is something wrong with either part of it or the whole thing.[code]...

I currently have a sql command that inserts info into a table through one of my statements. One of the tables columns is defined as an integer. The integer value inside that columns cell's is one that I would like to retrieve, and then set it to a value my enumeration (a string value) and later display on my datagridview.
The problem I am having is that when I retrieve the column's value from the table(let's say 1) I can't set the value of the rows cell to my enumeration type, it tells me the table holds integer values only and so I can't change it to text. How can I accomplish retrieving my integer value, setting it to my enumeration type (a string value) and displaying it in my datagridview in the same cell that the integer was?
