Redefining A Record Or String?

Dec 3, 2011

I have an external random file that can contain multiple record layouts. for example

record
.recordid string 1
.layout1

[Code].....

I know there's a very simple way to redefine positions 2thru11, as shown above, but i can't find it in several books I've looked at. Its some sort of a keyword like 'refer' or something like that.

Aug 5, 2009

I am using visual absic 2008 express edition. I am trying to produce two (FromNode, ToNode) random numbers and store in an array (ArrayTo(NoConnections)). The array should not have same values at the same time and the aary should not have the same number or the other way around. For example, The array should not have numbers like 22, 55, 66Šetc If the array has 13 and 45 then 31 and 54 is not allowed in the array and vise versa.

Can't Get This Array To Work?

Nov 19, 2009

The values for the 10 variables belonging to the modified array should be equal to the ages of 10 of your classmates. You must begin by gathering ages from 10 of your classmates and recording them for use in your program. Instead of calculating and displaying the total of the array values, find and display the average age of your 10 classmates.

Getting A Variable Array To Work?

Dec 30, 2011

ok, I got a lot of conceptual code for major chunks of the game's engine...like an inventory array of variables... he says that we will be using a lot of variable arrays, and I am trying to get a variable array dimmed in an inventory module, but when I try to declare what each index of the array should be, it says "declaration expected" and simply trying to reference the array from within another form, it does not register as existing...

the code is as follows, for he has not a clue how to program in vb.net

dim character_inventory(19) as array

and when trying to tell vb.net to set an individual index to nothing, it throws a "declaration expected" error...

character_inventory(0) = nothing is when it throws that error...

Multidimensional Array And The Variables To Get The Program To Work ?

May 5, 2011

I get what I'm supposed to do, and this is my 9th project in this class so I'm not new to the coding and how it works, but for some reason I'm having a hard time wrapping my mind around the multidimensional array and the variables to get the program to work. Here is the first part of the instructions I was given for the project:

Write a program that will determine the cost of a Yacht rental based upon yacht type, the size of the yacht and the number of hours the yacht is rented. There are three categories of yachts: Ranger, Catalina, and Excalibur; and three yachts sizes: 20 feet, 30 feet, and 40 feet. The rental cost is the yacht price multiplied by the number of hours rented. Create an array to hold the rental prices.

RangerCatalinaExcalibur
20 feet 95.00105.00125.00
30 feet110.00130.00150.00(prices per hour,
40 feet120.00145.00180.00 multi-dimensional array)

Use a data structure that contains the following fields: yacht type, yacht size, price per hour and cost of the rental. Limit the number of transactions to 20. Each time the Calculate Price button is pressed, look up the rental price from the price array and display it on the form along with the rental cost. Add the appropriate information to the data structure to create a transaction history.

Here's my code, the top with the variables:

vb.net

Public Class YachtRentalMainForm

'Variables

[CODE]...................

And here's my calculate button code where I'm having the most trouble:

vb.net

Private Sub CalculateButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CalculateButton.Click

[CODE]......................

I'm not getting errors anymore thankfully, but when I run the program... I choose my yacht type and size and input hours, it doesn't matter how many hours I put in - the price doesn't change. I know I'm missing something, maybe I've just been staring at it too long and need a fresh set of eyes to give it a look over and tell me what I'm missing? It also isn't calculating properly. 40 foot excalibur is supposed to charge $180 per hour and instead it's charging $125 flat rate.

Getting SQL & VB Code To Work Together?

Sep 20, 2010

I need to pass the values that I generate from SQL queries back to my VB code-behind window so I can apply a bunch of program functions to them. The queries work like a charm, and look something like:

SELECT Max(Number) FROM .dbo[00Masterlist] WHERE (County) = @County

and then in the next screen of the "Configure Data Source" tool I set up the WHERE and all is well.However, this information is only the beginning of my obligation to the project.It will display just fine in any data view I choose, but that's not what I want it for.I want to code with it from there. I've tried setting up the SQL as a string variable in the VB, but it reads the string as a literal set of characters instead of as SQL.I've tried stealing it from the form it prints to in a querystring, but that got really really messy.

Can't Get Loop To Work - ASP.NET | Dream.In.Code

Feb 21, 2010

I created this ASP.NET Web application and I can't get the amoritization table(MonthlyPaymentBox) to loop correctly. I think the problem is somehow in my code I am setting the TotalLoan = 0, but I just can't locate where that is happening. I assume this because instead of of starting the current balance at the users input, it starts at 0.

.net - Code To Install Files To The GAC Doesn't Seem To Work

Mar 22, 2011

Basically we ran into where, for whatever reason, we had to put some 3rd party dll in the GAC for it to work correctly. (The assemblies loaded, but had weird behavior and trouble finding types in the loaded assemblies. The app itself is a add in to another 3rd party program, so it must be something about how its being loaded.) So I tried to write some quick code to handle this without having to manually do this on each machine it was needed on. This is basically what the code boils down to:

Dim X As New System.EnterpriseServices.Internal.Publish
X.GacInstall(name)

Where name is the filename of the dll. This runs without error. It even add the assembly to the GAC. However, the application still experiences the same issue until you manually add the assembly in .Net Configuration window.
