I need to :
Read data from a file. The file contains the location and file name of a file and the name to which I want to save as (about 27,000). Then I need to Open the File with PDF Pro 9 and save as pdf in a specific loaction with the new name. Where to find some samples of reading, parsing and concatenating data and running a program from within a script?

I'm concatenating data files, but the problem is that I'm seeing some extra bytes where the files are joined. The new file has extra bytes. I had thought this was maybe a problem with encoding.Here are the methods that I've tried to use to concatenate the files. The first example I'm getting extra 0xA0 0x00 bytes.
Dim inputfiles() As String = Directory.GetFiles(sourcedir, pattern)
Dim bufSize As Integer = 1024 * 64
Dim buf As Byte() = New Byte(bufSize) {}

I need to parse a web page for blocks that contain open trouble tickets. The web page display several unresolved tickets and each one is inside a html divison labeled "issue-status". I've written the following code which does find the blocks, but when I try to parse its children to get its element fields (date opened, person requesting, history...) it instead pulls every element from the web page, not just the children.Is there a way to just parse the sub-fields under a particular DIV?
Code:
Dim theElementCollection As HtmlElementCollection
Dim strResult As String = ""

I'm using visual basic 2008 express to do some simple stuff. For this project, Im reading in one large text file.The top of each page has a header section that is always the same, except sometimes a dept# changes, signifying a new set of data.The first line always has the text "RunDate", so when I read that, I know that I'm at the top of the first page.After reading the first line, I'd like to immediately go to the sixth line and grab that dept# and store it.dept = left(trim(myline,7)(Its always 7 characters long) so I know what dept I'm working on.I'll then loop through and write each line to a new text file, until I hit the top of a new page.At that point I need to look at line 6 again. if the dept # is the same, I'll keep writing to the same file.Reading and re-writing from the text files is easy, I just loop through line by line, but I need to be able to jump down to the 6th line, and I don't know how to do that without reading each line to that point"
View 2 RepliesI'm busy with an applicaton which reads space delimited log files ranging from 5mb to 1gb+ in size, then stores this information to a MySQL database for later use when printing reports based upon the information contained in the files. The methods I've tried / found work but are very slow.
or is there a better way to handle very large text files?

I have a design question about parsing data in Silverlight. I need to allow my users to validate their csv data (they paste ten rows into a textblock), but I am not sure if I should attempt to do it on the client side where I don't have access to the textfileparser class or send the data to a webservice for validation. If I send it to a webservice how do I ensure the data is secure?

I have created a nested loop and want to write the value of a variable into a record in the database table. Typically I have seen that textboxes, etc are connected to the database. How do I update the details for one record as part of the VB function?
Details are (excuse the pseudocode):
For loop (y axis)
For loop (x axis)
Within these storing values x,y,R,G,B,Y,U,V,mask as integer

I was wondering if anyone knew of a good tutorial for parsing data from a text file and then populating the data into multiple text boxes. I have a text file with information pertaining to my form. The text file consists of key identifiers for each piece of information needed and I was wondering how to programmatically fill in my form by parsing that data.

I am concatenating a variable onto a path(string), i'm using a message box to display this for testing purposes, I can see that the variable is starting on a new line, which in turn when i try to open the file it doesn't recognize that the file exist...
Dim Path As String = "C:UsersstefanDesktopUni WorkYear 4ProjectsProject SelectionProjectProjectinDebug"
Shapetext = clickedShapes.Item(nextShape).Text.ToString.Substring(0, clickedShapes.Item(nextShape).Text.IndexOf(" "))
MsgBox(Path + Shapetext + ".txt")
This code works if I take out
" " + p.MIDDLE_NAME
Thus the remaining code looks like:
p.FIRST_NAME + " " + p.LAST_NAME

I have a textbox "myTextbox" and a listbox "myList" which shows a list of strings e.g "AAA", "BBB", "CCCC".When the user clicks on an item from the listbox the text must be appended to the end of whatever is in myTextbox with a space preceeding it. e.g " AAA".The user must never be allowed to delete the added text.The user must be allowed to manually enter text in the textbox but it must always be in front of the added text. They must never be allowed to type over the added text or after the added text.I have been trying to get my head around this for a day now and cannot figure it out.
View 7 RepliesI'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?
I am using VB.NET and I am designing a generic network architecture in which data can be transmitted in various ways. I am wanting to strip down things as much as possible, and I do not want to transmit in plain text. My question today is regarding ideas and example code (if applicable) as far as parsing binary data that is sent over the wire in VB.NET.I want each packet to have a very generic architecture such as <packet type> <address> <payload> or whatnot. I understand that I can use certain bytes as delimiters for these packet fields. I don't necessarily want to serialize everything being that for security reasons, the same library has to be used to deserialize the data.
a) Put my protocol into binary data where each field is delimited using a certain byte
b) Parse that data from binary at the other end.
Once again, I don't want to use plaintext since this can cause a bunch of overhead in comparison.

is it possible to communicate with a bluetooth device? I have a fairly simple heart rate monitor which has a USB stick, which connects wirelessly to the monitor.

I am trying to parse incoming data from a serial port that appears to be XML format but a few problems arise when going from a simulated setup to the real deal. I first made a this program at home using a serial port emulator and com port connector program that reads from a text file and then sends it through the com port, I then read it from the com port it is connected to it. My program is able to parse the incoming XML perfectly fine, I'm using an XML Literals syntax.
The problem I run into is when I setup my program with the device and try and parse the data that is coming out of it. The data I receive sometimes has a few lines of garble before it starts seeing my expected XML. Of course these few lines of garbled text throws me an exception, but even when it appears I'm getting a good clean start of my XML data my program still throws exceptions such as "unexpected end of line 1 line number (different lines)" or "multiple root elements line 1".
Am I going about this the right way? using XML Literals to process my XML string properly or should I use something else that will allow for not well formed XML? or am I just missing something. My device outputs data every 500ms and I can poll my device for stored data. An example of what I am receiving sometimes and what I am expecting is below. "The first few lines of text sometimes appear and sometimes don't" [Code]

View 5 RepliesLet me preface this by saying I'm VERY limited in my programming knowledge/experience using any language. I mean I have extremely basic capabilities and don't quite understand this stuff inside and out like most of you do.Anyway, I'm trying to code a fantasy football draft program in VB 2010 that utilizes the MS Internet Transfer Control 6.0. It will retrieve the HTML from a website, say ESPN, and parse the data into player names, rankings, and other stats. Should all be simple strings/sub-strings. It will then populate a DataGridView control so that each row in the DGV has the player's name, ranking, projections for the season, etc. After this has been populated, the program will be designed to allow me to draft players and assign them to the various teams automatically. I am the commissioner and we do an off-line draft, so I will just make picks for everyone and submit them online later.
