Im trying to make an on access file scanner, YES I know that C++ is better, but this is a concept of thought, trying to challenge myself to see if its possible in vb.
Anyways, I have a list of Hex definitions, my question is, how can I index this list so I can access the definitions faster. A definition looks like this:
The part after the equals sign is the HEX signature, while the first part is the name of the definition.
Basically what I am trying to do is index them somehow where I can scan faster, as I have over 60,000 definitions and I have to split each individual one in order to get the signature name. It takes about 45 seconds or so to scan a 500KB file. I need it to be WAY faster.
I have a networkstream (using C#/VB.NET). while on reading values coming like this:
&% 68 kg K A&% 23 kg K A&% 174 kg K A &% 68 kg &% 34 kg K A&% 2334 kg K A&% 68 kg K A &% 68 kg K A &% 2348 kg K A&% 78 kg K A&% 28 kg K A&% 68 kg
The numerical(weight) value will be continuously varying.
Every time i am reading the starting of the stream differs. But the pattern remains the same. How to split that into '&% 78 kg K A' which represents one set.
How to extract the weight value from this stream using Regex or any other methods?
I'm trying to find a pattern in a string, I guess is very easy but I'm terrible in regular expressions. I have a big text and I need to find all the next type of pattern: {a|b|c} That can be also something like this: {a|b|c|s|f|f|ft|r} or any number of items inside but at least 2 items so the pipe symbol is another key. Is this an easy regular expression? I'm using vb.net 2005.
i have a string array that i want to output to a text file. the array size is 10000. i fill the array starting from 0 with some strings. at the end, i only want to show the array from index 256 to the last array that is not empty (for eg. if the array is filled with data from 0 to 2000, i only want the text file to show the data from 256 to 2000 and ignore the remaining strings). Is there any function to do this?t i use is shown below
Dim myArray(10000) as string Dim strArray As New System.IO.StreamWriter("c:List.txt") strArray.WriteLine("{0,10}{1,30}", "Index", "Symbol")

I want my app to look for a byte pattern in a process and return the first memory address of that byte pattern. I know I should use ReadProcessMemory and a loop, but I don't really know how to create a function for that,
As a continuation of my other thread, "Finding A Pattern without a string Array (http:[url]....)", I would like to continue asking questions about enhancing a scanner with a few things:
1. Here is my code for finding signatures in a file:
'First the Signature Class: Interface Signature End Interface[code]......
I have a grid 10x10, at present is in the form of a multi-dimensional array:
my_Array(10, 10) as char
[Code]...
Additionally this shape can be in any orientation and more than 1 as in the above example.Does anyone know a quick way to do this? e.g regex?Or alternatively achieving the same result by using a different structure rather than a multi-dimentional array?
Is there a way to search for a string pattern in a string ?
i have 1000 of strings and example of one is - 'won 2 races in town, 1998, and then moved to'i wish to search for the ", ####," as all the strings are in the same format (note that the year is different every time hence why not using the instr)
I am struggling to extract a 'matched' string and wonder if I am missing something simple.Let's say my code finds a string 'abcdefgh -john. smith 1234567 a123-a-123-f the last search, abc, 123 ;'I am searching this string for the pattern '[a-z]###-[a-z]-###-*'I know this text appears in the string as 'a123-a-123-f'I would like to be able to return the matched string value 'a123-a-123-f' to a variable.If I place a wildcard * in front of the pattern, it will find the text, but obviously everything else in front of it, is there a way that somebody can think of to strip the variable without using the preceding wildcard?I am not worried about the wildcard on the end of the string as I can strip back to the last space.[code]
I made a form with text boxes in a 6x6 square pattern. It will do a streamreader from a text file a number that indicates the size of the array. Then fill in the boxes with the numbers of the array. Then it will calculate the rows and columns to see if they add up to a single answer. Then it will display to an output window if it is a magic square or not. Meaning if all rows and columns add up to a single number its magic. If they dont add up to the same number then its not magic. Then it will repeat this check and output from the information of the other arrays from the text file.
I know how to code for the streamreader and get it to add the rows and columns. Im not sure about what code I need so it can check the answer if its magic or not and repeat it till the end.
Here are the contents of my text file which it will read from.
Could someone please guide me on the correct format string to display a time in the following format? [code] Is there one format string I can use to accomplish this?
The known part is the [0] or [1] or whatever number in the brankets.the unknown part is the rest of the message.So if i have this string i want to cut it to smaller substrings that start with [ and end before the next [ .To make it more tough, sometimes, before the next [ there is another message that comes like: Jun 19 17:13:40 2012 timestamp And after that it continues with the next [
I've got an issue with a program I am writing. The specific issue is replacing characters in a parent string by finding, and matching, specific characters within it that are parsed from an external xml file. It's for a chat-like client.Here's the 2 classes I am using to pull the emote strings, titles, and id from external XML:
Imports System.Text.RegularExpressions Imports System.Xml.Serialization Public Class emote
I need to be able to serialize a class into a string, and I know of 2 patterns:
1) (normal) Serialization pattern
2) Proxy Serialization pattern
I've read [URL] (the only website in google that talks about the proxy-serialization pattern) and still cant find the advantage or benefit of using this pattern. Could someone explain what exactly is the proxy serialization pattern, or rather exactly what problem does the proxy-serialization pattern solves that the normal-serialization pattern doesn't solve?
I have some code that generates 15 random numbers between 1 and 100 and prints the 15 numbers in a listbox. I want to be able to find the max and min numbers in that list. How would I go about finding those values? I'm new to VB so a solution involving basic string/array manipulation would be preferred.
I have a somewhat unique problem that I have looked for an answer to and continually hit brick walls. The problem is this. I'm using vb.net to read a byte array from memory which total 32768 in length, which is converted to a string. The memory is the active console chunk in the game Call of Duty 4.
find the first empty value on an array?Say I have a directory and will occasionally be adding and removing items from an array to represent this. How would I go about making a loop until the entry is empty. I've tried various things like if null and that sort of thing but none of them seem to work- the problem is I guess that this array value is empty and the system can't deal with it without throwing an error message.Creating an array of a set size from the start isn't an option as I've no idea how big the directory will ultimately be.
Say I have an array of doubles sorted from smallest to largest. What is the FASTEST way to find the closest value in the array that is LARGER/SMALLER than the search value if an identical value is not found.
Code: dim myArray() as double = {1.245, 2.45, 3, 4.556, 5.4434} 'LARGER AND SMALLER SEARCH for 3 should obviously return 3 because its in the array. 'LARGER SEARCH for 2.46 should return 3 because it is the closest LARGER value 'SMALLER SEARCH for 2.46 should return 2.45 because it is the closest SMALLER value
I certainly can do this on my own, but I am looking for the fastest way.
I have a database which need to be assigned into array arr()(), e.g.
arr(0)(0) = aa arr(1)(0) = ab arr(2)(0) = aa arr(0)(1) = bb arr(1)(1) = ba arr(2)(1) = ba arr(0)(2) = cc arr(1)(2) = cc arr(2)(2) = cc
I need to find distinct / unique value in each arr(k)(0), arr(k)(1), arr(k)(2); where k=0..2. Then i need to insert the result into array cat as follows:
I've tried code below but it doesn't work. The assigning process into array arr()() from DB is OK. Problem only come up if I try to find the distinct value (If Not (cat(j).Contains(ds.Tables(0).Rows(i).Item(j))) ... End If).
For i = 0 To 2 list(i) = New Integer(3) {} For j = 0 To 2
[wink]You'll notice i dim'd n as integer = 0...[/wink] hehe I need a bit of advice on how to find the largest number stored as data in an array. For example vote(0) = 6, and vote(3) = 12, and lets assume all the other vote(n) are less. How do I pick out the big one?
I am trying to find a set of missing values between an array and cell values from a DataGridView. The array is a set of numbers from 1 to a user-entered maximum number. For example, if the user enters 10, then the array will have the values 1,2,3,4,5,6,7,8,9,10. The rows in the DataGridView might have values such as 2,4,6,8. I want to create a second array that would have the values 1,3,5,7,9,10. I believe I need to loop through the array values and compare them to the row values in the DataGridView. But I'm stuck on the method of either adding or removing values (or doing nothing) to the second array as the array value loops through the DataGridView. logic or some VB Code that will produce the results I'm looking for?
I have an array with wild character at the end. I use the value in this array in Select statement. Some times the array has same values. I want only distinct values in the array before the select statment. Code: for i=0 to count select * from tbl where item like ' " & itemname(i) & "' next I need distinct element in itemname array.
I am working on arrays and I am currently having trouble with searching and finding arrays. In this example, the user should be able to enter a Name, and it will output that person's stats.
Here is the text file (note, I should be able to go to this text file, add a few more names and the code should still work, which is why I am using loops,arrays,text files instead of if and else statements),
Kobe,29,6,4 Allen Iverson,28,7,4 Jason Kidd,12,10,9
So if the user enters Jason Kidd in the text box, this will display in another text box:
Jason Kidd averaged 12 points, 10 assist, and 9 rebounds.
[Code]...
All right now is the searching part. I really do know how to search for what the user entered and display the statement in a text box. I kind of have an idea of how to just get the name, but for it to get the name and then all the data for that name puzzles me even more.-I tried using .contain, indexof and few others.
I know to display the information in the text box will be something like:
