I am trying to figure out how to use the format.string() function This is what I have. I have 3 data string inputs of the format as folllows:
pcname bigservername (maybe 20 character max)
ip address ###.###.###.### (ex: 192.168.1.10)
macid ##-##-##-##-##-## hex values for # (ex: 00-23-AF-33-BC-CE)
[code].....
var queryString = string.Format("filename={0}&filestream={1}&append={2)", fileName, Convert.ToBase64String(b, 0, bytesRead).ToString(), 1);
above line of code giving error 'Input string was not in a correct format.'
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?
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.

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 am trying to display a number, stored in a dataset as a string, as a phone number. I have a label that Binds to a value but doesn't display the format that I passed as an arg:
<asp:Label ID="lbl005108002" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "phone number", "{0:(###) ###-####}") %>'></asp:Label>
As a test I tried to pass the formated string into the dataitem but that didn't work either. Is there something else I need to do in order to use this function?
m_Row("phone number") = String.Format("{0:(###) ###-####}", value)
The value displays in both cases as: 04152543926
I'm trying to create an address bar, much like Google chrome's, where you can enter a url and it will navigate to it or enter just text and it will search Google etc.
I've been at this for a while Googling away, but I can't find a reasonable solution. I know I could look for things like: 'http' etc, but these come in an almost unlimited number of variations. I could also created a webbrequest to test its existence, but I think this could cause an unwanted slow down in the programs operations.

I have a routine that exports data to HTML and works 99% of the time but now and again I get an error of Index (zero based) must be greater than or equal to zero and less than the size of the argument list on this specific line of the code
savef.WriteLine("<td style=" & Chr(34) & "text-align: left; vertical-align: middle; border: 1px solid; letter-spacing: 0pt; word-spacing: 0pt;" & Chr(34) & "><p>" & sRetMessage & "</span><br /></p></td>", True)
Now sRetMessage is declared and passed as a string and contains approx 5 lines of text with <br /> for each VBNewLine.
What I did notice is on one of the errors I have caught, the last 3 characters on every line are =20 sRetMessage is extracted from a text file and so the contents are out of my control.
why i'm getting this error? If it is the =20 within the string, why should this matter as it has been stored and passed as a string value
