I am having a question on parsing XML files. In my local folder c: estrdl, I have a bunch of xml files.... what I want to achieve is to extract the contents between <commandtext>. The extracted information is basically a SQL query.... Next step is to extract the FROM Clause from the query and save that piece of information into a file with the same of xml file and suffix is "FROM", for ex, if the xml file is called abc.xml, the extracted piece will be called abc_FROM.txt....

I am looking for a way to save and load the values of all my controls present in my form.My form has around 100 controls spread over 7 tabs. The controls include (Multiline) TextBoxes (Strings), NumericUpDowns (Integers, Decimals) and Checkboxes (Booleans). If the user clicks the save button a "Save File" dialog should appear allowing the user to specify the directory and the filename of the save file.All the values of the controls should then be written to that file.If the user clicks the load button an "Open File" should appear where the user can pick a previously saved save file. All the controls should then adopt the values found in the save file.I have implemented Application Settings in my form, and now when I click save, it saves the control values through My.Settings.Save(). If I click load it loads them.However, my project requires that multiple save files can be made to reflect multiple configurations. As I understand Application Settings only allow for a single .config file in the Application Data folder.So how can I code a save/load routine to save/load different configurations?
View 1 RepliesI 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 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]

View 1 RepliesI have to generate an XML file from several database tables. I could use the WriteXml method of the DataSet to do it, but the database tables are really huge and I can't add all those tables in the DataSet at the same time or it may cause a problem because of the big amount of memory used. Then I decided to use the DataTable's WriteXml method and save table after table, but the the generated file only stores the information of the last DataTable.WriteXml's call. How can I preserve the previous XML data when adding all that information?

View 6 RepliesI have a textbox on a form that is set to allow dragdrop operations from txt files.Basically you drag a .txt file onto the txtbox, the content of the text file is displayed in the textbox.All is working fine, however after the textfile is displayed in the textbox, the text box text is for some reason is highlighted.I don't want the text to be highlighted (or selected) after it's being displayed on the textbox.Second issue, after I close the file that I dragged, for some reason even if I didn't make any changes to the file, it is acting as if the file has changed.In another words, if I open a text file using my MenuItem Open item, and if I do not change the file, If I close the file it's fine it closes.However, if I close a file that I draged into the text box and then close the file without changing anything in it, the stringcompare function is telling me that the file has changed... I can't understand why.

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?
