Why Does Only Part Of Colors In Arraylist Display

Jun 10, 2011

I have a puzzleing situation where only 120 of 151 colors defined in ColorList(i) display.

In the following code, btnsetup_click assigns 151 colors to a matrix of rectangles in a picture box. When 1 of these rectangles is clicked, it assigns the color to btnPen or btnBrush, depending on a left or right mouse click. Hovering over the rectangle displays the name of the color in label 'ColorOver'.

This all works fine except only the colors 0 to 119 from the array are actually displayed in the picture box. Yet, if I hover or click over the missing colors, the color name is displayed and the button is assigned the color that should be displayed.

Dim ts As Integer = 25 'sides of toolbox squares
Dim tc As Integer = 24 'Tool columns
Private Sub btnSetup_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSetup.Click

ArrayList Search For PART Of String?

Jun 10, 2010

I have an ArrayList, and i wish to search it for a specific part of a string. Like the InStr() function.I can only find the WHOLE string. The ArrayList has strings like "This=Is A String", so if i do a check with ArrayList.Contains. It will only search for the whole string, and not something IN the string. Perhaps i need something like Starts With .

Code:
dim wordArr as New ArrayList
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If wordArr.Contains(TextBox1.Text) Then

Forms :: Resolved Search And Display ArrayList Stored In A Hashtable?

Mar 25, 2009

I am new to VB.net and I am trying to work out an exercise from a book I am reading on VB. Basically I am storing some book information in a hashtable using a class called Book to store the book information. I am trying to work out my Search and Display All procedures. My Search will work for the first value in my arraylist but not for any other values. I even added the ISBN to my book class to try and use this as a search point. The ISBN is used to pull the item from the hashtable as well.

In the main code I am having problems with the ButtonSearch and ButtonAll.

Copy The List Of Principal User To Arraylist To Use Arraylist.indexof?

Dec 1, 2011

What I am doing is iterating through all the groups that belong to the top group (Generic reports). Then I take advantage of the GroupPrincipal.GetMembers(True) which will recurse through a given group name. I test to see if the user exits under that group and if true I put the group name in an arraylist.

I use the for each principal in GroupPrincipal.GetMembers to loop through each returned user to see if they exist.

Is there a way to put all the returned users Principal.Name from a given group in GroupPrincipal.GetMembers into an ArrayList? This would allow me to to use Arraylist1.IndexOf to search for user. Which would be much faster then iterating through a returned list using the for each construct.

Sub RetAllMbrs(strUser As String)
Dim oPC As PrincipalContext = GetPrincipalContext() '<- this is function somewhere else in the code

VS 2008 - Reading ArrayList In My.Settings And Add Another ArrayList To It

Sep 21, 2010

What I need to do is read an ArrayList in My.Settings and add another ArrayList to it. The first think I'm trying to do is load My.Settings.Records into myArrayList. I'm not quite sure on the proper way to do this. I've tried things such as Dim myArrayList As ArrayList = My.Settings.Records, I'm not sure if I need New and I'm not sure if I need .Clone or .CopyTo.

Then I have another ArrayList myArrayList2. To get this into myArrayList I've done: [Code] Then to save it back to My.Settings I've done. My.Settings.Records = myArrayList. The problem is I keep on getting Object reference not set to an instance of an object error on the AddRange line. My.Settings.Records is definitely an ArrayList and it will sometimes = Nothing. The objects will only ever be strings.

Multi Form / Part Application Need To Make Part Protable For Transfer

Feb 22, 2011

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts

1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers

2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly

3. the config files

anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.

Create An Array Of An Array (or Arraylist Of An Arraylist) To Hold Strings?

Mar 20, 2012

I want to create an array of an array (or arraylist of an arraylist) to hold strings.I want to fill an array1 with string values Then add this array to array2. - but only taking up 1 row in array2 e.g something like array2(index)=array1 Then clear array1 then loop through this again with different data, and add it to the array2.so will end up with something like

array2(0)... contains a collection of array1 data
array2(1)... contains a collection of different array1 data
.. and so on

i think i need to make new instances of array1 each loop, but not sure.I dont mind if it uses arrays, or arraylists, or lists, or structure of arrayslists?

The exception I get is very vague and comes from the API. All i get is, "ARException Occured".
