VB 2008 - Parse Log File And Only Display New Entries
Jun 2, 2009
VB 2008
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Dim Reader As New StreamReader(Application.StartupPath + "/pbucon.log")
'TextBox1.Clear()
Dim Reader As New StreamReader("C:/Documents and Settings/Dorinda/Desktop/pbucon/pbucon.log")
Dim Line As String = Reader.ReadLine()
[Code] .....
I am trying to parse a log file and only display new entries containing the word "say". I have this set on a button click event, but I prefer a timer or something, but the textbox flashes everytime the timer ticks so I am using a button right now..

I am parsing many files after I click the button.I want to display the process name when I parse a file. So I am going to display it as
Label3.Text = "Parsing File " + FileName
The problem is the screen is freeze if too many files will be parsed. So designing an event to display the file name that is processed is a good idea. But I haven't any experence on it.
Private Sub ExtractButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExtractButton.Click
Dim saveFilein As String
Dim FileName As String

I made an application that writes to a text file in csv format, and on another tab, there is a listbox where the user can click the "View Report" button and it will display the information from the text file in a list box. Right now, I am really pleased with it because I was able to use "split" to get all of the separated values on there own individual lines.Now I am wondering, is there a way that I can display one entry at a time in the list box, and then maybe implement "previous entry" and "next entry" buttons so that the user doesn't have to scroll down through the entries to view them, they can just hit next entry and it will go to the next line in the csv text file and display the information from there? I have tried doing it a few different ways, here is what I have so far for the "View Current Report" button:
Private Sub btnViewCurrent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnViewCurrent.Click
lblReport.Text = "Current Report"

I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables
Dim strName As String
Dim strArtist As String
Dim strPrice As String

The following solution should allow the user to enter 'colors' to a combo box; however, if the color is already entered (in an upper, lower case or mixed case format), then the 'Duplicate Color' message should be displayed. I get the message, but my color is also being converted to an upper case format in the combo box.

I'm messing around with regular expressions and I can't seem to figure out how to parse this file.It's basically a lua file containing a table like:
TableName = {
["QuotedString"] = {
["QuotedString"] = {
[code]....
Some things with the file are standard, like the "TableName" (Never in quotes) starts the table. Variables always have [" "] around them and then equal something like ["Test"] = 0. However, the variable could have multiple variables within it. split up the file within each {} and then try to parse each ["QuotedString-Key"] = 0?

I have spent the last 20 plus hours trying to parse a incredibly small XML file with Xpath. I understand that it is a ready only, extremely fast way to pull values out of an xml file. Here is the string I am working with. I have a 3rd party function that returns results, based on these xml results i would like to retrieve certain vaules.

I am trying to parse a very large text file for certain strings. The text file is part of a level-making software for an old game I play. The text file basically contains all the information the level designer software needs, but the only important bit is the 'texture information'. Basically what I'm trying to create is a little program that parses the text files and shows the user a list of every texture in that text file. The problem is, the strings denoting textures are not really easy to find, and I can't think of any sensible and fast way to get them...

I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?

I have a gridview which returns a number of columns, sorted by date.If possible I would like to display each distinct date only once. So, for example, if there were 5 records for 18/06/2009 and 3 records for 19/06/2009, they would be displayed as follows;
'Date Name
'18/06/2009 John
'<no date here> Mary

I am new to Visual Basic and I am having some problems with a programming challenge. The user is told to enter their city, state, and zip into a textbox seperated a certain way (Ex. City, State. Zip). The program is supposed to display the City, State, and Zip in three seperate label boxes broken up. So far the code that I wrote for the button click event displays the count up to where a comma is found (City). Im not sure how I would display the word instead of just the count. Also, finding the state and zip after the City is found. I know I have to use the IndexOf method as well as the Substring method.
Here is what I have so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click
Dim strCity, strState, strZip As String
Dim strInput As String = txtInputData.Text
Dim intCount As Integer
'Obtain the count for city
intCount = strInput.Length
strCity = strInput.IndexOf(",")
lblCity.Text = strCity
End Sub

windows service app I am developing to audit events in the Windows Security Event Log. I am using the EventLog class to read entries from the "Security" event log. I have set the log to raise events when an entry is written so I can parse the data. Here is where my problem comes in. If I run the service on Windows 2003 I can get all the data I need from each entry, but when installed on Server 2008 the EventLogEntry ".message" property comes back with useless data like this, "The description for Event ID '4738' in Source 'Microsoft-Windows-Security-Auditing' cannot be found." Under Server 2003 the message property has good data. Using the Event Log Viewer in Server 2008 I can see that it is rendering the correct data, but I am having a heak of a time doing the same. The "replacementStrings" property has the corresponding data that I need, but it appears to involve some other steps to get the data localized to the event provider, but I do not know how to do that.
I also checked the registry HKLMSystemCurrentControlSetServicesEventlogSecuritySecurity on both the 2003 servers and 2008 servers. They are identical execpt the 2003 has an entry the 2008 server does not:
String Type: GuidMessageFile
Value: %systemroot%system32NtMarta.dll

But i've a problem, everytime i hit the button "Save Settings" in my form/application it will re-save the settings to ini file, causing duplicate entries :(
Does anyone knows how can i avoid it to happen?
And, how can i retrieve a setting from the ini file to a textbox or messagebox or something?
(before anyone start saying me to use .xml, i was reading and i prefer the .ini files to what i'm doing)

I've imported data from a text file using Streamreader and populated a listbox with this in 3 columns. I now need to
a) get a total value from the 'Hours Worked' column (sum) and
b) put in a calculation to populate an extra column for each entry (Gross Pay) where values are not imported but entered as a result of a calculation.
My current code is as follows:
Private Sub btnRefresh_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRefresh.Click

I have data entries in my database that have a common field. For example:
account_id type user_id
1 new 1
2 old 3
3 new 1
4 old 1
I am using a query like this(mysql): SELECT account_id, type, user_id FROM table WHERE user_id = 1
This is just all theoretical. The problem that I am having with this is it is only returning the first result in this case account_id 1. How can I get it to find all the results with the user_id 1 because in the way I am thinking that it is failing is that it is finding only the first result and then ending?

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 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]

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")
