I started with not knowing anything and I have built 2 programs over the last month and a half and have learned valuable information from the help of this board. I have 1 last hurdle before I am done and I am hoping to get another tip for this. First of all let me start by explaining what I have done.
[Code]...
Simply put, I have a text file full of reg values. I want to search the text file for X number of reg values. I want to then, have those values and their dword values (whole line + next 3 to 4 lines in the file) listed in either another text file or an Excel spreadsheet. Regardless of the format, I would like to have the values sectioned off for each of the values searched (probably tables of some sort).[code]...
View 1 RepliesOn a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.

View 7 RepliesI've been tasked with writing an app that reads in various text files(.csv, .txt) in different formats with different delimiters.I then need to compare certain data in these files and report the differences.There are a couple of columns that are common between the files, but they aren't in the same place, and there is inconsistent and unnecessary header info.There is extra data(columns) in these files that I don't need.Should I parse these files into a datatable? Should I create an object for each file type to format the data and get rid of the unnecessary info?I'm not sure about the best way to tackle this problem.
View 1 RepliesI have been tasked with creating an app that will read in various text files(.csv, .txt) and compare some of the data contained within.
I thought I would read in the files and convert them to datatables. Once I had them in a datatable I figured I could remove the unnecessary rows/columns and then sort and compare the pertinent info for differences. The difficulty is that the various files are formatted differently so I will need to get each type formatted correctly. Is this the best approach?
I have read in a .csv, parsed it into a datatable, but I'm having trouble with the logic/coding to get rid of the rows and columns that I don't need. Also, I'm not sure how to handle a row that has a cell with a comma seperated list of values that will need to be split into individual rows.
i want a code for compare between 2 text files A.txt and B.txt all record in file B.txt includes in file A.txt but with different value.the digits with color red are accounts and the digits with color blue are values.i want to compare between A.txt and B.txt based on accounts,when find the accounts from B.txt in A.txt copy the full record for these accounts from A.txt and print it in new file C.txt

File A.txt:

I want to create my special full-text index using text files, without database.I saved records ids for every word in index, in text file..Now if I want to search for tow words together; I have to get ids that is shared between these words by comparing text files of these words ids; and saving the result in other text file.[code]But now the problem if the first word has 100,000 ids and also the second word same it; the loop will take too long time! It will loop 100,000 * 100,000 times!How can I find another way to compare these files quickly; or another idea for my full-text index with text files?
View 4 RepliesI am new to VB.Net, but I can tell you so far I love programming. That said, I'm building a tool basically to parse and display simple plain text log files. I'm hitting one stumbling block that really has me frustrated.
Other tools are able to load huge log files (500MB even) in a number of seconds. My tool, basically hangs loading a file that is maybe 5MB.
I'm using the MyString = StreamReader.ReadToEnd to read the contents into a string, and then RichTextBox1.Text = MyString to display the contents. That said, I really want to display the contents in a datagrid, but there has to be a better way of doing this?
How can I get my application to load larger files and display them faster? What am I doing wrong?
I'm trying to create a little program that compares the text from two richtextboxes and displays the differences in text between the two. I.E. one text box contains "i like cheese" and the other contains "i like blue cheese" I want it to display the word blue in a 3 richtextbox. I'm just not sure what the best way to go about it is
View 5 RepliesWell, I have a MenuStrip1 with submenu "Open File1" and "Open File2".
An OpenFileDialog1, two RichTextboxes and a button called "Check".
When I open txt files into RichTextboxes, by clicking the check button i want it to compare the two contents and focus the differents with a color (let's say yellow).
I have created a simple project and at the end it only says with a MessageBox if files are the same or different.

I am writing my own script for a simple calculator that determines if a number is prime, and its prime factors.[code]The loopcount = compare - 2 means I want the loop to be 2 less than the square root of the answer so that when do a descending calculation (loopcount = loopcount - 1) it doesn't see if 1 or 0 is a factor of the answer. for the calculations after that, I want, every time n1 = n2 (a whole number factor of the answer), I want to report those results to a text file (n2 and n3) in this format "(n2, n3)" then go to the next line. and continue to execute the loop until the loopcount is zero. Currently, when I run the code, the application closes when I click the prime button (button that runs this code) and I don't know why. This is my first semester in school, and have never coded before, so I am a definite laymen with code, but I really really want to learn it (hence why for fun im just creating algorithms for different things).

View 5 RepliesI currently have an excel spreadsheet that has a macro that displays information from my sql server. Everything works fine with it. Im trying to embed that into my vb project though. Anyone know what the best route to go would be to do this. Should I try to convert the vba macro and display the results to a dataset?Or should I try to recreate the connection through VB to display the results? or is that sort of the same thing? Or should I try something different? [Code]
View 1 RepliesI am building a vb.net application with VS2010. The aim of the application is to change sln. files from VS2005/2008 versions into VS2010.I am using a Form with 2 text boxes and 2 buttons. When I click the 1st button it reveals the sln file in the text box. Then i have a 'convert' button that I want to use to 'convert' the file that appears in the first text box. I have come quite far with the source code but am just a bit puzzled as to how i can retrieve the VS2005 sln files and to get the 'convert' button to display the text in the 2nd text box.[code]

I've been trying to compare two text files line by line but I was only able to compare the file lengths. I'm creating a dance mat game and I have a text file of the steps that should be taken to get a perfect score and a text file of the actual steps taken by the user. Each text file contains a time stamp and a binary value indicating which arrow was stepped on. I'm using streamreader and streamwriter to write and read the text files.

I'm willing to compare a textfile (whatever) which contains a few lines of text. After the comparison it should download and replace the "changed" folder/file. E.g.
(Local txtFile)
maps: 1.0.0

db2. 1.0.0
(Server txtFile)
maps: 1.0.1
db1: 1.0.0
db2. 1.0.0
my knowledge of VB.net is limited and i'm really trying hard to figure this problem out...
what i did was create a list box and populate it with a directory ("C:Documents and Settingsuserfolder1")...
once the listbox displays the files from the directory, i want to select a certain file and that file will be opened up in a rich text box.What i found to display the directory in a listbox is:
Dim directory As New IO.DirectoryInfo("C:Documents and SettingsjtanDesktopRECV")
Dim diar1 As IO.FileInfo() = directory.GetFiles()
Dim dra As IO.FileInfo
Dim files As String
