I am new to vb and I am having so much trouble with this. What I need to do is this: I have a form application for winter sports equipment rental.I have a listbox filled with the equipment for the user to choose from then I have a combobox for the user to select the duration they would like to rent it. The book that I am using has no examples I can refrence and i have had no luck online either. I am posting what I have so far. However, i think I am going in the wrong direction. I have been working on this for so long that I think I have over thought it and made a mess of it. I am thinking that I need to add a new class for rentalRates then use enum of durationType and equipmentType but I am unsure how to move that way. That is using a enum, a 2d array and a parallel array? [code]

I'm interested in having a generic 'Try Catch' clause, with some case statements or if/than statements within the Catch part so that I can handle different error types differently. some way to get ex.Errorcode or ex.ErrorType that differentiates the different errors to a unique value.
How can this be done?
Try
'some code taht will throw an error'
Catch ex AS Exception
If ex.ErrorCode = 20 then
' Do something'

So what i am stuck is when the user selects a product from the drop down menu...the user can enter price . But i need to display a error message when the user enters text instead of numbers for prices. I tried try parse method but it displayed the error message but did not transfer the entered price to the array.

I have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.

I am trying to create a "stock Price Program" for an assignment that will allow you to type in a stock symbol such as "goog" in the client side and the server side will respond with a price for that stock symbol, this price can either be hard coded in or read from a text file. I have done a lot of research and have a good understanding of how sockets work.
My issue is that I do not understand how to get the server to reply based on what the client sends it. I have a working program that allows you to send text to the server and it should reply with the same text and date but i think the client is just re-typing the text instead of receiving it from the server and I can't figure out how to get the client to receive back from the server

To create a program that asks for input then uses an else statement to create a handling fee balance.
Input: sales record - first name, last name, purchase amount, balance before purchase
Output: report - full name, old balance, purchase amount, handling fee, new balance
Definitions: handling fee is 5% of the old balance if the old balance is less than $1000.00 else it is 2% new balance = old balance + purchase + handling fee
Processing:
Ask for and receive sales information
Calculate new balance
Print output report
End the program when a purchase amount of 9999.99 is entered
I wanted to create a login system that would have 3 tabs 1 for regular login, 1 for admin login and 1 for account creation. So far so good. It saves the accounts by saving them in a .urs file in the map called /Users/. However when this map does not exist it will show a error. I would want to know what code or so to put into the form_load which will make my program create the map /Users/ if it does not exist. As im not familiar with all the codes and stuff. The only thing i can come up with is
Mkdir "/Users/"
but then ofcourse it would create the folder users everytime i start the program. not i was still "Hello Worlding" a few days ago, so i really am unfamiliar with any sort of high-skilled programming which i probably dont understand.
I have a project setup, where depending on a certain variable one of two controls will be used. Either the default webbrowser or the gecko control. Now I can load either one fine dynamically but I can't work out how to use either one depending on a variable result.To load the one I know I want is easy enough..
Code:
Private WithEvents wb As Skybound.Gecko.GeckoWebBrowser
wb = New Skybound.Gecko.GeckoWebBrowser()
Me.Controls.Add(wb)
[code]....
I want my webbrowser to be called wb as I already have all the event handlers written.

I created a sql query to check if the mobile number is registered or not. If its registered, it will send the new pin code to the customer and if its not, the customer will get a message that "This number is not registered or you are not authorized to this"... something like that... Sending of new code is already working. I just dont know how to make it as conditional statement like PHP. After you query on PHP, you can just set a variable and make a conditional statement..Here is my script in vb.net:

how to create a conditional statement if the value of rows is zero or not.I want my output to something like...

View 23 RepliesIn my first application I need to create a multi-level "IF" statement and I am a little lost on how to proceed. The idea is to do figure out an estimate on costs based on the quantity of products being sold. I can do this in Excel, but the VB code escapes me.
So I'll show you in psuedo code what I want to do.
IF comboBoxA = 1 and comboBoxB = 1 then
value X
IF comboBoxA = 2 and comboBoxB = 1 then
value X
If comboBoxA > 3 and comboBoxB > 1 then
(comboxBoxA * costA) + (comboBoxB * costB) = Value X
I have another IF statement that will work off the calculations here. Haven't figured this one out yet, but I haven't gotten there yet in my form.
If Value X > Y Amount then
Offer product Z as a better idea

In my programming task I've gone down a dark alley and wished I hadn't, but there is no turning back now.
I'm building up a SQL statement where the table name, column name and id value are retrieved from query string parameters i.e. ("SELECT [{0}] FROM [{1}] WHERE [Id] = {2};", c, t, id)
But it isn't as bad as it looks, I'm protected: Only authenticated users (i.e. signed in users) can execute the Page_Load I'm checking that both the table and the column exists beforehand (using GetSchema etc.)I'm checking that the Id is an integer beforehand All my tables have Id columns The database connection is reasonably secure

View 2 RepliesI am trying to create a LINQ query statement that retrieve intersecting data from 3 datatables (dt, dt1, dt2). My first attempt to do so with the following LINQ query statement was successful: [code] However in my design, I would need the LINQ query statement to be dynamically generated, because I want a user to be able to retrieve intersecting data entries from VARIABLE number of datatables. In this case, the first option is not as good as the "INTERSECT" query operator, with which I can just easily connect each SQL query statement with a "INTERSECT" operator. The problem is that my second attempt using the "intersect" operator fails, and after many trials and errors I still can't get it to work. [code]
View 5 RepliesI have an SQL statement which i need to code in vb:
CODE:
Notice the fields prodno1 and prodno2 in the table structure.. this is part of a number of sql statements i need to run and put inside a loop. my problem is i want to automatically use this same code such that on the next loop, this sql statement is going to be:
CODE:
Note that in this "2nd loop"
- the table name is now r3 from r2 in the first SQL statement
- there are now prodno1, prodno2 and prodno3 instead of just prodno1 and prodno2
- in the WHERE clause, the p.prodNo becomes p.prodNo2
And so on and so forth.. so for the 3rd loop
- there's going to be r4
- there's going to be prodno4
- in the WHERE clause i will use p.prodNo3

If AdultsizeRadioButton1.Checked = True Then
adulttotaldecimal = quantityinteger * adultpricedecimal * hoursinteger
ElseIf ChildsizeRadioButton2.Checked = True Then
childtotaldecimal = quantityinteger * childpricedecimal * hoursinteger
[Code] .....
Ok, everything has worked when I display the information.... up until the accumprofitdecimal variable. When i display that value its NOT what it should be. For instance i'm putting in a quanity of 1 and an hour of 1 for an adult then for a child, the extended price comes out properly as $2.15 now the code accumprofitdecimal += extendedpricedecimal SHOULD add the extended price (2.15) to the accumulative total. but when i display the accum profit total it shows a number that makes zero sense... is accumprofitdecimal += extendedpricedecimal not correct code?
