Asp.net - Parse A Date From A Textbox And Store It In A Date Variable?

Jan 3, 2012

I am trying to parse a date from a textbox and store it in a date variable

Dim enddt_2 As Date = Date.ParseExact(txtenddt.Text, "dd/MM/yyyy", System.Globalization.DateTimeFormatInfo.InvariantInfo) 'txtenddt.Text
expenddt_1 = enddt_2.AddDays(-1)
enddt = enddt_2.ToString("dd/MM/yyyy")

enddt is a Date variable and when i convert enddt_2 to a string i get the error as

Conversion from string "17/01/2012" to type 'Date' is not valid.

Let me clarify, if a value in textbox is 17/01/2012 than after parsing the value is changed to 01/17/2012 (my systems Region and Language are dd/MM/yyyy) in enddt_2 and when i try to convert to dd/MM/yyyy format and store into a date variable i get the above error. This error comes only for the dates after 12. i.e a date variable accepts a date in MM/dd/yyyy format.The dates before 12 work fine, i.e for all dates from 1 to 12 there is no error.How can i make enddt store the date in dd/MM/yyyy format.

Why Date Shows Up As Date Before Date Trying To Parse?

Sep 9, 2010

I have a date time as a string, eg. "2010-08-02", I'm trying to convert it to UTC with the following code snippet..DateTime.ParseExact("2010-08-02Z", "yyyy-MM-ddZ", CultureInfo.InvariantCulture)When I print to the console, I get the following: 8/1/2010 5:00:00 PM.Is there a reason why the date shows up as the date before the date I'm trying to parse? I could just add a day to this to advance to the original day.

C# - Parse An Expression And Retrieve A Parse Tree?

Jun 8, 2012

I just want to parse simple expressions like IIF(FVAL(PFC) = TRUE, (IIF((ORGVAL(BAS, "2012/12/31") + ORGVAL(DA)) < 6500, (FVAL(BAS) + FVAL(DA)) * 12%, 780)), 0)`After parsing this I should be able to know what functions contains what parameters.

[Code]...

I'm stuck with .Net Framework 2.0, so no Linq or lambda expression goodies for me. Also I want to include the code in my custom library and not just reference it. Can anyone point me to some good library or code.

I just need to parse and not evaluate the expression and find what tokens are in use. After finding the tokens I need to change the expression string before parsing, like if the function ORGVAL is used then the parameter passed has has to be prefixed by an underscore. Like ORGVAL(BAS) will transform to ORGVAL(_BAS). Some functions can have tow parameters like ORGVAL(BAS, "2012/12/31") and this will transform to ORGVAL(_BAS, "2012/12/31")

NOTE: IF THERE ARE OTHER WAYS OF DOING IT PLEASE LET ME KNOW. I WOULD LOVE TO AVOID A PARSER AND LEXER.

Best Way To Parse An XML File

Sep 17, 2011

I have an app that the user selects information and it writes to an XML file. The user can increase and decrease the information in the XML file so it is dynamic. The other app reads the xml file and uses it to complete tasks. Since the XML is dynamic my code needs to account for that. Right now I have only allowed the XML to have up to four values in a certain node, I would like to allow more but I will need to increase the Select Case function.[code]

Parse XML That Don't Have A File For?

Oct 28, 2009

How can I parse XML that I don't have a file for?

I get the (dynamic) XML from an HTTP request, but all the XML classes I looked don't seem to be able to accept a string variable rather than a file.

I tried using XPath like this, but it just hangs.

Code:
Dim document as XPathDocument = new XPathDocument("http://www.myurl.com")

How Best To Parse A Text Log File

Jun 22, 2010

I occasionally have to search a very large text file as a troubleshooting step. The file is continuous text (with spaces between much of the text) but almost everything is date/time stamped. The text is actually messages between two machines so I'd like to insert a line break after every message so that I can follow the protocol exchange. Thre are also a few key words that I'd like to again, separate with a line break.

ListView - How To Parse File

Nov 8, 2010

I'm working on a project and am kind of new to parsing files as well as listviews. I am trying to parse a file. Here is an example of what I need to parse.
a:b:c:d:e:f:g
a:b:c:d:e:f:g
a:b:c:d:e:f:g
Each entity needs to be stored in it's respective column in the listview. So therefore I need to read the file in line by line.

My File Doesn't Parse

Nov 2, 2009

So, I'm writing an application to extract data from an excel sheet and output it nicely in a text boss, sounds simple to me at least. But for some reason ( and it was working fine earlier, don't recall changing anything.) The file is not being parsed before being stored into the array. And since it's not parsed, it's not seeing it in the array as I don't have it set up to look for a substring.[code]...

Parse A Text (log) File?

Jun 2, 2009

I am using VB.NET 2005 (if that matters).I need to parse a text (log) file in which to process lines like:

Program Up at: Tue Jun 24 11:32:53.656 2008 - TerrificProgram.exe
<some lines here which I ignore>
0.00:24:16 - Emergency Stop!
<more lines to ignore>
Program Down at: Thu May 29 22:22:56.000 2008

where the 0.0:24:16 is the offset in TimeSpan format (d.hh:mm:ss) relative to the 'Program Up at" datetime.The 'Program Up at: <date/time>' line I successfully detect (in another function which works) and as a result a set a Boolean flag that I am in a valid <Up> - <Down> sequence and I also set a Start-up DateTime var to which to add the offsets later.

The task is to convert the TimeSpan at the beginning of the 'Emergency stop' line to a regular DateTime expression and to write the converted line to another log-file.Simple, isn't it?The function I use for the above purpose is:

Private Function IsTimeSpan(ByRef InputLine As String, ByVal ProgStart As Boolean, ByVal DTofProgStart As DateTime, ByRef NewDateTime As DateTime)
Dim iLine As String = InputLine
Dim Index As Integer = iLine.IndexOf(" ")

[code]....

What I am doing is I pass each line ('InputLine' parameter) from the original log-file to the function together with the 'in <up>-<down>' flag ('ProgStart' parameter'), the start ot program DateTime (in the 'DTofProgStart') and I want the NewDate to hold the real datetime of Emergency event occurence (not its offset).

What happens is that I successfully detect the lines of interest but the NewDateTime is not updated (though 'ts' is in the correct format and the assignment 'NewDateTime = DTofProgStart' correctly assigns the passed value).Another curious thing is that the line

InputLine.Replace(testStr, NewDateTime.ToString("MMM dd HH':'mm':'ss yyyy"))

does not change the original TimeSpan beginning of 'InputLine' with the regular DateTime (though not updated) in 'NewDateTime'.Why?

Parse A CSV File That Has Column Headers?

Mar 22, 2011

What I'm trying to do is parse a CSV file that has column headers, and map those headers - ideally to a class.The tricky part is that I need to be able to support various mappings because it will be interacting with different systems that give the headers different names. Additionally, being able to combine fields would be extremely helpful.

Fortunately, the CSV will always be correctly formatted with all fields encapsulated in double quotes.

Parse A Text File By Line?

Jan 20, 2011

I'm running into a problem whenever I try to parse a text file by each line. I know I could use stream reader to read line by line but it is a lot easier to simply use split() and I would also like to know the reason why split() doesn't work.

For example, I created a file "test.txt" and filled it with the following text.

text1
text2
text3

then put the following code in the load event of the form (a button click would work the same).
