View 11 RepliesAm writing a windows app using vb.net 2005. The app captures a string variable from the user. As each file within a directory is read, I want to match the stored string within each file. If I find a match to the string, I want a list box to be populated with the name of the file. I have added Imports System.Text.RegularExpressions and tried using the match collection.
For example: My direcotry has 5 text files. I want to match a string "PARENT" in the text of all these 5 files. The list box should output the name of each file where the string was found.

I have been searching all morning for a sample showing a simple "find" example for an ASP.NET Webform, where a "find" button is used to find a string in a Textbox, and then Highlight it, like Word does.

Is there a way to Select the Length and Start of the string in ASP.NET. The Winforms code is very similar to the VB6 code, so maybe I'm just missing something simple.
I'm amazed at this situation. In QBasic, you could just easily GET and PUT whatever you wanted at the exact position in the file that you wanted. Now in Visual Basic 2008 I'm just completely stumped.
I can't use FilePut or FilePutObject because of a twisted issue. It adds a couple of bytes to describe the length of the data being written: what's the point of BINARY read/write if it won't allow you to write EXACTLY what you want and nothing less or more? There's a way to turn off this issue, and that's by setting the parameter StringisFixedLength to TRUE, but that's where the twisted part comes in. You can't do that. As far as I can tell you have to redefine the function using SUB, for example:
[Code]...
My.Computer.FileSystem.WriteAllBytes. To my amazed surprise, this function doesn't even bother to include the possibility that I might want to put the data in a specific position within the file! I can't believe this. You can either specify to APPEND at the end or not, in the latter case apparently resulting in a write to the beginning of the file. No option at all to specify where in the file you want to put the data. I can't believe this.
How do you write to a SPECIFIC position in a binary file in VB 2008, and do it without the program deciding to add a few "informative" bytes to your data before it's written (totally undermining the whole point of binary files)?

View 20 RepliesI am creating a class that searches a binary file for a specific customer number. I am using a binary search that keeps on slicing the file in half until I find the customer number while is sorted. Once it finds it I am positioning it at the first instance of that Customer number as there can be multiple records with the same Cus Number.
Now here is my question. I now need to loop through this Customers records and do some data base searches. Since I want to make my class as generic as possible what should I pass back to the calling class? An Array with all their records. If I do this I have to loop twice, once in the class and once when it passes the array bac to the original calling class?

I need to add some information to a PDF (Trim Box proporties, actually replace Media Box proporties with Media Box and Trim Box proporties), and I dont have the support in my PDF-motor. So I found out that I can use Notepad++ to open the PDF as a text file and simply add the Trim Box properties as a string and save it. Now I want to do it automatically with vb.net. When I use Stream Reader/Writer the PDF gets destroyed and loses information (Stream Reader dont read all the NUL, SOH, STX etc. I guess). I tried to read the PDF using ReadAllBytes/WriteAllBytes and then it works good, but then I don't know how to replace "Media Box ..." with "Media Box.Trim Box.". I try to use IndexOf but I can only search for single Byte not the whole string. I'm not good in binary and thats perhaps the problem :-). Does anyone have a better way doing it or how do I search for my string "Media Box" in binary?

Binary Search in ListBox
View 4 RepliesI am trying to write a program which performs a binary search. The user will input the name of a state in a textbox.I have a listbox which is populated with the 50 states in ABC order.The middle of the list must be determined and then determine which half of the list the state may be located. If the middle item is less than the state name the state should be in the second half of the list. If it's greater than the state name is should be in the first half of the list. The calculation for looking at the middle itemi the list is:
middle = CInt(first + last)/2)
There is a variable 'flag' which is initially set to false and then will be set to true if the state name is found. The variable first is initially set to 0 and last needs to be set to one less than the number of items in the list.Below is a very rough program fragment.
Code:
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
Dim i As Integer
Dim flag As Boolean = False
Dim first As Double = 0
