Find Specific Characters (items) In String Array (or List) And Then Merge Them?
Mar 8, 2012
I'm having a problem recently, a logical issue so hard to determine various examples.I need the text that is inserted in textbox, which has been altered or modified or twisted to have a proper format through line accordance and constant white spaces etc. And some cases I stuck at defining the If statement within the loop. Here's an example of a text I'm trying to reformat.[code]I'm using Microsoft Visual Studio 2010 Ultimate version with Microsoft SQL Server Management Studio. This code is being fired on mouse click event of a button control. This is a snippet of my code there are more filtering after but here is what should be changed.

I have an HTML string and in that string are certain variables that I need to replace with database values. The variable names are dynamic but all begin with the characters "@@" (just two ampersands, no quotes). Is there a way to get all the words in a string that start with "@@"? I'm assuming you would use regular expressions, but not sure how to begin.

I'm having issues with finding something in list, and removing the item, ignoring the case of characters in string.
The code goes:
Dim listItems As New List(Of String)
Dim pattern As String = "AbC"
Dim array() As String
array = {"ABC", "abc"}
listItems.AddRange(array)
Here I'd like to remove all items from listItems, that are abc, no matter what case single characters of item are, including mixed case items. So in this example, every items should be removed
listItems.Remove(listItems.Find(Function(r) r = pattern))
If I change pattern to match the case of item, then item #2 gets removed:
pattern = "abc"
listItems.Remove(listItems.Find(Function(r) r = pattern))
How can I find item in listItems, ignoring the case characters in pattern?

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?

Is there a way of merging (importing or whatver is the correct terminology is) the data from an Array in to a DataTable woithout looping. I already know how to loop through the array to populate the DataTable with new DataRow but I'm looking for something much faster if it exists. I've got a 1 dimensional String array i.e. 'String()' that I need to populate a DataTable with new DataRows.

I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

I need to return everything between the 2 dashes:
"xxx-12345-xxx"
Here's my conditions:
Sometimes the middle part may contain more than 5 characters, so it could look like this: "xxx-12345AB-xxx" Sometimes there's no second dash, so a string could look like this: "xxx-12345"

I am working with a list of points. It is declared as a global in my form.[code]the only issue is that instead of New Point(100,100) i need to be able to navigate to the previous 4 records in the list. pull out the 4 x vals the 4 y vals and boom there you go. In the old days id make a simple loop and get r done but im not sure the syntax to step through the list that way.

How can I find variables in a string of text and display them.
For instance usually I could use the * or ? characters (in ol' batch files) to mark variable character positions.
For example, I am looking for a string "Happy" & ???? & "Birthday" in a file looking for 4 characters between happy and birthday. Is there a simple way to find these characters utilizing a variable or is there a different way to do it? Would I have to declare?? as 4 specific character spaces that need to be displayed?

Following is the format of the data stored in my arraylist.
A-Amsterdam
B- Brussels
C-Canada
so and so forth. I wan to search my array list by passing just the first few characters till '-' So if i have something like AA-Test then i want to pass just 'AA' to check if it exists or not.
I know that i can use contains or binarysearch but it does not serve my purpose as they both compare objects.

I have one dimensional array that is being returned by an NVP function, the problem is that I want to count the number of ID's returned by the array to set the limit. For instance the array comes in this format ID0, ID1, ID3.... IDn, Name0, Name1, ...., Namen, Surname0, surname1, ...., surnamen etc... I want to know the n+1 number of ID's so that I can set it as the upper limit of my array to be able to loop through without setting an arbitrary number.

I am writing a program using editable list boxes that will then be compared to a string later. I have no problem editing the listbox, but I am having trouble figuring out how to compare the list of things to the string. I envision using either a "for/next" loop or a "do/while" loop.
Mostly, what I need is the way to read the list box one entry at a time, in order.

I've gotten a listbox control to populate with a list of installed fonts, but I need to be able to click a button and remove the selected item from the listbox. How do I do this? Every time I try, an exception is thrown.
Here is the code:
Public Class Form1
Dim fonts as New Drawing.Text.InstalledFontCollection
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I need to determine the ranking of the List items specified by one specific property of the items.
I have the following Class:
Public Class LevelA
Property items as New List(Of LevelB)
Public Class LevelB
Property factor as Double
ReadOnly Property rank as Integer
End Class
End Class
For example, let's say I have three items in the List. I have set the factor property for the first item as 5.50, the second item as 6.60 and the third item as 3.30.Now I should be able to get the rank property of each item (the highest value should be ranked as 1). Here the first item in the list should have the rank as 2, the second item as 1 and the third item as 3.
What kind of procedure is needed for the "ReadOnly Property rank as Integer" for returning such values? It should somehow be able to access the list in the parent class probably?

How do I Extract all Characters in Unicode, UFT8,iso-8859-1 to 9 etc to a list or array In VB?I have a SQL Database of which contains values from 51 languages. I need to detect which ISO-8859-? Was used to encode the string value. For example Turkish Characters i.e. "Ö Ş ş ğ ü Ç" Once I have the correct ISO, I need to convert the Chars with-in the string to Unicode using only if the string value contains values that are not UFT7, and convert the string to HEX?The reason I need to detect the ISO etc is because we are sending SMS, of which jump from 160 characters to 70 if a special characters are used, i.e. "Ö Ş ş ğ ü Ç" Is there a simple way to extract the ISO-8859 Character Set to a Array etc, or is there a simple way to check if the character exists with a ISO-8859 data set?

I'm developing a program to tweak the settings of the Thief: Deadly Shadows video game.The tweaker program is designed to load and configuration profiles so the ttlg/T3Ed Guild community can share tweaks with each other and then apply those setting to the game's ini files. A little more info here: [ame=http:ur]UNDER DEVELOPMENT - Thief 3 Gold Tweaker -l.... TTLG Forums[/ame] & here are a list of tweaks the tweaker program will apply to the game: [ame=http:[url].....
Anyway, I managed to load and save the config profiles but I'm stuck on applying those settings to the game's .ini files. The main problem is finding the right string. Thief: Deadly Shadows .ini file has settings for xbox & PC. I only want to change the PC settings in DEFAULT.INI:
[XboxStartup]
ShowIntroMovies=True
ForceCopyFromHardDrive=False
ShortIntroMovies=d:content 3VideoTextureseidos-logo.bik; . . . etc.
GameStartFiles=d:MediaFont12.xpr, . . . etc.[code]....
I want to change "ShowIntroMovies=False" under the "[PCStartup]" section when the user clicks "Apply Changes" on the main form.One way I could go about this is to look for "[PCStartup]" hold the line number it's on, then look for the "ShowIntroMovies" string under that line number. There are several instances in the game's .ini files where the same setting exists but they exists under different sections. So how would I find a specific occurrence of a string?

I have a situation where a user can enter just about anything they want into a text box.Whatever they enter in the box, I need to split the string into an array of strings where each item is one word. For example, if the user enters All State Insurance, I split that into a string array:
sParams(0) = "All"
sParams(1) = "State"
sParams(2) = "Insurance"

I am trying to program a noise reduction algorithm that works with a set of datapoints in a VB.NET DataTable after being helped with my other question. Basically, I want to take two integers, a coordinate value (yCoord for example) and a threshold smoothing value (NoiseThresh), and take the average of the values in the range of (yCoord - NoiseThresh, yCoord + NoiseThresh) and store that number into an array. I'd repeat that process for each column (in this example) and end up with a one-dimensional array of average values. My questions are:
1) Did anything I just say make any sense ;), and
2) Can anyone help me with the code? I've got very little experience working with databases.

I'm still learning VB.net and there is a bit of code I have added which is an array and I want to add a list of items to the array. If that makes sense. I have 6 classes two have arrays.
Here is the code from one of the classes
Public Function getItems() As Array
Return _LevelItems
End Function
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.
