I'm having trouble creating a global array that i can use in other functions.
I have this code right under "Public Class myClass":
Dim LoadedPlugins As Array
Then in a function I have this:
Dim PluginList As String() = Directory.GetFiles(appDir, "*.dll")
For Each Plugin As String In PluginList
Dim Asm As Assembly
[Code]....
Now obviously that doesn't work, how can I add the tmpPlugin to an array or list so I can use it in other functions?
The main thing I need to be able to do is loop through all the loaded plugins and execute the CustomFunction in a separate function than the one that loads the plugins listed above.
Does link text mean I have to return a concrete implementation? Even though I am using svcutil with the /r that includes my entites(where IMyInterface is defined). I get no errors but it changes all List(of IMyInterface) to list(of Object) and I cannot deserialize it on the client
Error: list(of object) cannot be converted to list(of IMyInterface).
I'm trying to create a small program where someone would select one of five items from a list box (Hot, Medium, Mild, Sweet, Zesty). When they select this, they then enter in a qtyTextBox the quantity they want, ie.e, 1, 2, 3, 5,... Then they the Calculate Button, which then the total would go into the preDiscountLabel box, where it would calculate the amount they want * the sale price. Here is the Price Listing:
I have an array of 26 strings from A to Z. Then, I am creating a random list of 7 alphabets from this array. Now I want the user to pick first 2 alphabets manually and then on a click it will display the rest 5 randomly generated after subtracting first 2 picked ones from the whole 26 alphabets array. how this can be achieved in lists.
Recently I have learned visual basic 2008 express edition and developed programs for data crunching and analysis. The VB 2008 express edition has microsoft visual studio 2008 v. 9.0.30729.1 SP and .NET Framework version 3.5 SP1. Now I want to create x-Y (date-Y value) graphs using the crunched data stored in an array list simulating a data base access. I download and installed the "Microsoft Chart Control for .NET Framework " and try to learn to use it within the VB 2008 express edition using the tutorial. It seems that the chart control did not get installed?
1. Do I need at VB 2008 professional to allow using the chart control? 2. Why after installing chart control, there is no change on the items under the NET components within the Toolbox>ChooseItem>. 3. How do I get to use the chart control under VB 2008 express edition. 4. Any code available to generate versatile graphics without using the chart control? Because the chart control has tons of classes already it seems the best is to just use the existing and downloadable chart control?
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?
I'm trying to make a trading card computer game with my own trading cards and I was wondering if I can load the sprites of all the cards into an array that looks like this: Dim Card(342) as CSprite (CSprite class helps display the sprite on screen) and not have any problems displaying each one on the screen.

I have a Comma Separated value file in .txt format... simply put, its a bunch of data delimited by commas and text qualifier is separated with ""For example:
"So and so","1234","Blah Blah", "Foo","Bar","","","","" "foofoo","barbar","etc.."
Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into VB.net and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..
i have issue returning a list in a web method. here is the code
<WebMethod()> _ Public Function getTags(para_parents As String) As List(Of getTypeDetailsByParentName_Result)() Dim context As New PPEntities
[code]....
the error is
Value of type 'System.Collections.Generic.List(Of SaftyonRoad.getTypeDetailsByParentName_Result)' cannot be converted to '1-dimensional array of System.Collections.Generic.List(Of SaftyonRoad.getTypeDetailsByParentName_Result)'
I am trying to get a count of all the times a byte sequences occurs in another byte sequences. It cannot however re-use a bytes if it already counted them. For example given the string let's assume the byte sequence was k.k it would then find only 3 occurrences rather than 5 because they would be broke down like: [k.k].[k.k].[k.k]. and not like [k.[k].[k].[k].[k].k] where they over lap and essentially just shift 2 to the right.
Ideally the idea is to get an idea how a compression dictionary or run time encoding might look. so the goal would be to get down to just 2 parts, as (k.k.k.) is the biggest and best symbol you can have.
I have two rich text boxes, and two buttons on my screen. The first button grabs HTML from a URL and then converts the HTML to XML which resides in rich text box 1.
The second button is to grab the XML from the rich text box1 and then parse it to grab all the input elements by their ID.
My issue is that my parser isn't doing anything. My guess is that I'm not quite getting the XML from the first rich text box.
What would be the best way to grab the XML from a rich text box load it into memory and then parse the XML to grab all the ID tags?

I developing a roster application (asp.net with VB + sql server) to let user input shift duty record, proposed screen as follows:for the database design, each staff will have one record per day.[code]I want to create a multi dimensional array to bind the gridview.Is that correct that I create a arraylist (for 7 days) and then a subarray for each day? How can I create a 7 dimensional array & sub array under this 7-D array in asp.net + VB ?
I have a class called Car. Car has a bunch of properties i.e. Car.Color. CarService has a method called GetCars(). Within GetCar, I have a loop that appends a List of, you guessed it.. Cars.[code].....
I get: Value of type '1-dimensional array of Namespace.Car' cannot be converted to 'System.Collections.Generic.List(Of Namespace.Car)'. What would be the best way to convert this 1-dimensional array' back into a List of Cars?
I want to create a big list box that has lots of default values in many lines so they can then be edited later.Right now I have in my initializer:
Dim counter As Integer = 0 For counter = 0 To counter = totalNumber listBoxThingy.Items(counter) = ("DEFAULT DETAILS TO BE COMPLETED") Next
with my list box called listBoxThingy and totalNumber a previously defined constant of how many items I want in my list box.yet when I try to run the code I always just end up with the first list value containing the text.Even if I put a counter=counter+1 it still only gives me the one completed value of my list box?
I would like to know how I can get the list of possible choices to Intellisense for my class object, like it does with MsgBox.For example, when creating a message box you type MsgBox "Test Message Text", vbYesNo, "Test Message Title".In typing that, when you type the comma just before the vbYesNo, it gives you the possible selections for button types in a drop down list: i.e., vbYesNo, vbOKOnly, etc.I have a class called clsKeyState. what it does is turn on/off/toggle key states, such as CAPS LOCK, SCROLL LOCK, NUM LOCK, etc... I have set my property for it as Get/Let "State". When I call it to set a key to on/off I will be doing it like this: KeyState.State WhichKey, On/Off/Toggle.I would like the WhichKey part to automatically display all the possible selections that I define, such as CapsLock, NumLock, Scroll Lock; and I want the On/Off/Toggle to display those specific items also (On, Off, Toggle). I will be using the ability to create these displayable options for many more things in my project than just this one simple class.
So I have a program that is supposed to support a small business. I have the work completed and the professor said it was correct but I wanted to go do a little extra. Basically, on the Order screen, you begin to type the name of a customer/supplier/employee into a text box and a list of names that fit the criteria pops up in a list box (lbMatchingAccounts). When you select it, you can hit enter new order and be transported to the Order Details screen to enter the new order.
I want to create a sorted list, where I enter a name in two separate text boxes(Jones, Brown) and their values in two other textboxes(200,500), then in a fifth text box I enter one of the names and it gives me a messagebox with its corresponding value. Here is my code below.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim saleslist As New SortedList(Of String, Decimal)
How can I create an array of a class that I have declared? I have this class named partswith properties of frame, engine and date, and i want to know how could I store them in an array .
I need to be able to refer to a set of controls on a Windows form using an array, but I'm having a few difficulties.
The Windows form (WForm.vb) contains two textboxes (TextBox1 and TextBox2).
In Module1.vb I have created an array reference to the textboxes thus:
Public wf As New WForm Public ReadOnly TB() As Control = {wf.TextBox1, wf.TextBox2}
Then, in WForm.vb I have tried to refer to the textboxes via the array:
eg.
TB(0).Text = "Change text to this"
I know that the array is referring to the textboxes, because when I hover the cursor over the line 'TB(0).Text = "Change text to this" ' in debug mode, I get the following:
(0)|{Text = "Change text to this"} (1)|{Text = ""}
but for some reason, the text in TextBox1 on the form isn't actually being changed! (There is obviously no problem with change the textbox's text at this point in the code, because I've tried substituting the array reference 'TB(0)' with a direct reference to the textbox 'TextBox1', and the problem disappears.
I need to create an Array of Labels. I am using A With Code block to set the properties of the Labels as well as the Data Binding. I want to set the LabelIndex inside this block as well. How do I go aboute this?
i want to declare an array with a name that is the value of a variable. I need to do this because i want to create arrays from a text file that i'm reading.Basically, if someone could make this work then i should be able to change it to fit my use.
Dim var1 As String = howdy
Dim var1() as Integer
In this case i'd like to be declaring an array with the name 'howdy' that stores integers. In reality i'm looping a bunch of read names and would like to create an array for each name i read- but i'm quite capable of sorting the rest.
I want to create a generic list - but I want to specify the type at runtime - is there a way I can do this? using reflection perhaps?Something like this...
Public Shared Sub create(ByVal t As Type) Dim myList As New Generic.List(Of t) End Sub
