I need to create a code that searches an array of movie titles. When the user enters a specific string, the first movie title that contains that string is displayed.

View 2 RepliesI'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:
Widgets.xml
I would like to execute a single RegEx Replacement that would result in the string being:
ACE_Widgets.xml.
Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:
^ACE_{1}[dD]+
Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml
The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.
The following posting is close to what Im looking for, but with the inclusion of the *ix directory path prefix, and the use of preg_replace() in PHP, I'm having a bit of a struggle getting it to work with what I need to do:

How will I select a substring with 2 criteria? I have a Richtextbox where I select a number after a : with this code; For Each line As String In Richtextbox1.Lines Dim equalsPos As Integer = line.IndexOf(":") + 1 txtFound.AppendText(line.Substring(equalsPos, line.Length - equalsPos)) Next This is working ok, but the whole line.length is appended for number2. The line ex. Some text:my number some text-my number2. I want my number appended to txtFound, and my number2 appended to txtFound2. With my code only number2 can be appended correct.
View 4 RepliesIm making a class that represents a file. Im making a sub that reads data from one byte array into many properties. Now i need something that returns a byte array but only the first 4.

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

sealed = cleara(sealed)[code].....
Here is how this work so far
Add my location to open ,Create H,G,F for items in open list
Find lowest F
Find adjacent nodes
Loop through nodes
If node is not walkable then ignore
If in sealed ignore (this is where im stuck at)
If not in sealed and is walkable then if in open compare G scores else add to open
I have a listview with two columns of data in it. I want to capture all the items in the listview into an array. The array will have two dimensions, one for column 1 and the other dimension for column 2. I am a little lost on how to iterate over the listview items. I figure it would be a for each statement. Its also the actual call that passes the found item and sub item to the array I am struggling with.
View 2 RepliesI have an array with 280 items in it. I only want 140 of those, so I want to pick them at random. So I need to generate a random number between 0 and the source array's getupperbound property. I think. Is there a more suitable way to pluck an item from an array. I wonder if there's a way to ensure that you don't choose the same item more than once. I suppose I could randomly sort the source array and choose the first 140 items, that would ensure I don't get a repeat item. But could be inefficient if the source array is much larger than the destination array, because I'd be shuffling more values than I need to shuffle. I suppose it's a sampling problem.

How would I add the item list to this? Where do I put it? Like underneath it or in the items class? That code is in the Level class.
I am trying to build a context menu for a little "random quote" generator project. Most of the context menu for the NotifyIcon I can create at design time, but I need to create a submenu of file names that the user can choose (check) to be included in the quote population.
I originally did this in VB6 and it worked, now I get a Null reference error. The problem occurs in the Sub BuildChooseFilesMenuItems. Code follows. (Basically, I need to read in the filenames, make them menuitems and keep track of their "checked" state. It is dynamic because the user could add new quote files to the directoryy where they are stored.
