this checks my file for any position with latdif < 30, I want this to be on a timer but I want it not to open the text file everytime is this possible?
In my program, I have a condition I need to constantly check for. When my program gives an error, I change a label to a different text, lets say "fail" for now. I'm trying to make a condition where the program constantly checks for the label change to "fail" from the start of the program. I am having trouble trying to get this to work.

if there is a way that you can close a form and reopen it. The reason is because I have created a tic tac toe game, but at the end I want them to be able to play again. The problem is that if I want them to start over I would have to set alot of stuff back to 0 and or change the buttons on the screen etc. Is there a simple way to just close the form and have it reopen?

The program has an MDI parent and its child forms. When opening one of the child form, the program seems to be working fine (it populates data from mysql and presents it to corresponding textbox, list and other controls). When you click Edit and save the data, the data is successfully saved and updated. But when you close the particular child form (without closing the MDI) and reopen it again, it cannot populate the controls (textboxes, etc.) with data.
create a function that parses the input "4+7-4/4*4=" from instr into an array named tokens(1000), as string, and returns the number of arrays, or perhaps a negative number if there is an error in the input.
Dim tokens(1000) As String

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.

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.
I have a script that parses the value from between two parenthesis -now i need to modify the script to exctract the name after the second underscore and before the third underscore...is there a way to do that?...This is a vb script task in side of a ssis package

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]

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.

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.
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]...

View 1 RepliesI 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?
I am trying to parse a date from a file name.The File's Name is like "FILE_NAME.20110831..No extension or antything.[code]
