Check If A Quotient Is A Whole Number Integer?

Oct 31, 2010

I've just begun using VB2008 Express. As practice, I'm trying to create a simple program that allows users to practice their basic arithmetic skills. I've just run into one hiccup.

I have a procedure that generates random numbers for the program to spit out as text that the user will then do arithmetic on. I'm trying to create a loop that checks, in the case that a radio button selecting division practice, that the potential quotient [code]...

Filter A Dataset Using A Number Different Inputs, Selected By A Number Of Check Boxes?

Mar 3, 2010

I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

ATM System - Check Card Number Matches Up To The Users PIN Number

Mar 13, 2009

I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.

Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.

Safest Way To Check For Integer?

Feb 24, 2009

This is probally more of an elegance question than functionality. I am looking for the absolutely safest way to check for an integer from a string and an object,

Using most of the built in functions for this in .net seem to generate a first chance exception, displayed in the Immediate window, and over time they just build up. what are the implications of these exceptions as they don't seem to affect the operation of the system.

Here are my two attempts, both feel clunky and I know there has to be a better way than using VB.IsDBNull and Integer.TryParse... Or am I just being anal.[code]....

Check Password As Integer Function?

Oct 30, 2011

I am doing a project.."Some Password". the criteria is that the password should have 1 numeric and 1 non numeric and atleast 6 characters. The code I worked on..(below)

Function CheckPass as Integer
Dim
blnContainNumber As
Boolean
Dim
blnCotainNonNumeric As
Boolean
[Code] .....

When I compile this code...it gives me a Messagebox error that I wrote.."Password Invalid" even though I type the password that meets the criteria. I think the problem is that I don't have..."if atleast one numeric then" and "if atleast one non numeric then"...

[2008] Check Integer For Null Value Instead Of 0

Jan 19, 2009

Basically, when you set an Integer to "Nothing" it seems to equal the same value as if you were to set it to 0. So, in a function that returns an Integer how can I return something that will show that the function failed? In most cases I would use -1 or something but in this case I need to allow for negative values too.

Here's some more detailed information: I'm using the GetValue method of the Microsoft.Win32.RegistryKey class to read a numeric value from the registry. The GetValue method has an optional argument that you can pass in that specifies what should be returned if the value did not exist, normally I would use Nothing but in this case because I am storing the returned value in an Integer then it is just the same as if the GetValue method returned 0 (which is a valid value in this case).

Example:

vb.net
Dim Reg As Microsoft.Win32.RegistryKey = My.Computer.Registry.LocalMachine
Dim SubKey As Microsoft.Win32.RegistryKey = Reg.OpenSubKey("SYSTEMCurrentControlSetControlTimeZoneInformation", False)

[Code].....

Compute Whether An Integer Number Is Prime Or Not ?

Feb 28, 2008

What i'm trying to do is compute whether an integer number is prime or not. The program performs this analysis for all odd numbers from 3 up to an input integer limit, for example 100. If the integer in the range 3 to limit is prime, a message stating so is printed. Otherwise, a message is printed that lists at least one other integer divisor. The output for each analyzed number consumes one line of text.

A sample output is shown below:

Limit is 100:
Number 3: is prime
Number 5: is prime
Number 7: is prime

[CODE]...

I understand I need to use loops, boolean functions, vbmath(), strings and multi-line out via concatenation. So I can put this is words how I think it should be done but not so great putting the code together

Test all integers up to the SQRT of the number (100)

limit = math.sqrt(100) + 1

Followed by 1 For statement
For c = 0 to 100 step 2?
And an If statement
If ......
result = false
