Search Text File To See If String Is Present
Apr 10, 2012So 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.

Open A File Using Last String?
Apr 7, 2011On my program, the user inputs a "name", "lastname" and "ID number" and saves the file, so the file will save as follows:
namelastname idnumber.txt (with nane/last name together).
My search feature asks for the name and last name and id no for the file and it will use that input to open the file.
But now i want a search feature that just asks for the id number. So how i do it so it reads the last string after the space (so after namelastname) of a text file, in this case, the ID number the user has inputted?
I thought of it theoretically:
the user inputs an id number in search, it records the length of that input (say 5 characters) and just reads the last 5 characters of the file name in directory X (that being, in this case, the ID number).
Search A CSV File By An Input String And Return All Lines That It Is Found?
Dec 12, 2009I 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.

Read Text File / Search For String Then Add To Line And Write Back?
Nov 18, 2010I 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.

Correcting A String - Open A File To Read And Then Display It?
Sep 18, 2009Ive figured out how to open a file to read and then display it, and i can probably work out how to write a string to a file. The part i am stumped by is this. Say i open a text file with the following text I has a badger i then want to correct this to I have a badger.
Its just an example and not for a grammar corection program. What i want to do is detect what was said and alter it acordingly. I presume this would come under string manipulation but i cant find any details on this.

Aug 12, 2011Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything
