string (Product_Type: "Hardware", "xxx", "xxx") the Product_Type is constant and has several instances within the file but the "Hardware" changes. I need to show all the values inside the quotes of the "Hardware" string to a listbox.

The format I need is a group of numbers in a text file and it looks like this and it will always look like this:xxxx x xxxxxxxx xxxxxxxxx x xxxxxxxxxxx xxxx x
The problem is that it can be anywhere in a text file so I cannot search by a particular line.
How can I search for this type of string format in a text file?

So I am trying to create a Win App to make copying files using Robocopy easier and eventually other tasks. Basically what I have so far is a Button that calls the Sub Robcopy_EXE. There is a tab on the form with 100 check boxes, one for each terminal, that will be designated by the user and a check box to determine if you want a detailed report or not from Robocopy. I also have a text box for the user to input the first 3 octets of the site IP Address. The check boxes and Input field are used to create string "Terminal_input" which is what runs Robocopy in CMD. Robocopy logs its progress to a text file that I have labeled "Status.txt". That is as far as I have gotten.

I was hoping someone could assist with the following coding; I am trying to search a very large csv file (approx 200,000 lines) for a user defined string eg "0100020789" and I essentially want to print all the lines that contain this to a text box on screen. Please not that the csv file does not have standardised column headings, each line is different. There would be approx 5 lines that contain the input string.
I am concerned with the v large csv i am using which will prob slow everything down, but then I thought if simple text pad application can search for a string in complete files with similar sizes like that and return a result in less than 1second, then it must be do-able.
I want to search for a string entered in a column of a datagridview in a text file.If this string exists in the file then allow the user to enter it otherwise dont allow the user to enter the string.Also,since I am reading data from the database into the datagridview, I have not added columns to the datagridview using edit columns option. How do I do this in vb.net.I tried doing something like this:
CODE:
I would like to read an HTML file, search each line to see if it starts with </head>. Then add the centering code after it. That line at destination file should read:
</head><table border="0" cellpadding="0" cellspacing="2" width="760"align="center"><tr><td>
After this I don't care to search for anything. Just read from source and write to destination. I know there are programs out there to find/replace text in series of files but I am not allowed to use external programs.

View 3 RepliesI have written a program that uses an array of the english alphabet and Morse code. I also built a form with a input box for the alphabetic information and an output box with the Morse Code. What i am trying to do is basically type a word like "Hi" in the input box and produce the Morse Code equivalent in the Morse Code output box. [Code] This works but only one letter at a time. Do i need to Parse the string of characters one at a time, and then run it through a loop like i have created?
View 6 RepliesI'm using the following code to try and search a listview (I got it from msdn):
Dim atem As New ListViewItem = ListView1.FindItemWithText(TextBox2.Text, True, 0, True)
If atem IsNot Nothing Then
ListView1.TopItem = atem
End If
Then I got the " Object reference not set to an instance of an object" error highlighting the following line: ListView1.TopItem = atem So then I tried this:
Dim atem As New ListViewItem atem = ListView1.FindItemWithText(TextBox2.Text, True, 0, True)
If atem IsNot Nothing Then ListView1.TopItem = atem End If it still isn't working.
I have a non standard text file, ie its not delimted etc, its pretty much free flowing. What I want to do is to search for a specifc string eg. "xyz123" and then replace it with what a user types into a text box, lets call the text box and its contents "txtreplace".
I am trying to replicate a find and replace function essentially, but will need to tailor it later on down the line, but this will be a starting point.

View 2 RepliesIs it possible using Reflection or some other method to obtain a reference to a specific class instance from the name of that class instance? For example the framework for the applications I develop heavily uses public class instances such as:
Public bMyreference as MyReference = new MyReference
Then throughout the application bMyReference is used by custom controls and code. One of the properties of the custom controls is the "FieldName" which references a Property in these class instances (bMyReference.MyField) as a string. What I would like to be able to do is analyze this string "bMyReference.MyField" and then refer back to the actual Instance/Property.
In VB6 I would use an EVAL or something simular to convert the string to an actual object but this obviously doesn't work in VB.net. What I'm picturing is something like this:
Dim FieldName as String = MyControl.FieldName ' sets FielName to bMyReference.MyField
Dim FieldObject() as String = FieldName.Split(".") ' Split into the Object / Property
Dim myInstance as Object = ......... ' Obtain a reference to the Instance and set as myInstance
Dim myProperty = myInstance.GetType().GetProperty(FieldObject(1))
Not sure exactly what I need to do to make this work, so my description may be lacking at first.Essentially I am writing a program launcher that recreates itself each time on load. It pulls the data regarding the tabs and buttons from an SQLite database and builds itself dynamically at run time. I get my problem when I pass the tab name through to the function that creates the buttons. I need the name to pull the right set of buttons from the database and I then tried to use the name to place the buttons on the right tab when I create them, but the debugger calls it a null reference because it doesn't point correctly to the tabpage that I'm trying to make it point to (at least that is what I'm guessing). Any ideas on how to make this work right?

View 3 RepliesI am trying to perform an action if the index of a string contains a certain value, but it's just not working quite right and I could use a hint if anyone has done this before.The application pulls in a .txt file and manipulates it to create 3 other different type of files. It is currently set to pull the information from line 3, but the output program that supplies the file will probably change to line 2 or 3. I need to either search the whole string or the index of line 2 and 3 and then do the following manipulations. It will not return the value of line 2. This is what I have tried, but is not working. The code commented out at the bottom is what is currently there.
