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"...

I am trying to write some code to check the AD password age during a user login and notify them of the 15 remaining days. I am using the ASP.Net code that I found on the Microsoft MSDN site and I managed to add a function that checks the if the account is set to change password at next login. The login and the change password at next login works great but I am having some problems with the check for the password age.

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]....

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)

I am trying to understand why the two code samples behave differently. I always believed the If() function to mimic the If language feature. Or am I looking at a behavior of Nullable(Of Integer) that is causing this?
Sample #1:
If Not String.IsNullOrWhiteSpace(PC.SelectedValue) Then
Dim pcFilter1 As Integer? = CInt(PC.SelectedValue)
Else

I need top create a function that gets the next integer in the sequence of 1 to 60. Each time the function is called, I need it to increment from what the last value was and return the next number as the result. It also cannot return the same integer in 2 consecutive calls. When the count gets to 60, the sequence needs to reset back to 1. I would like to function to have no parameters.
I have created a function that does this using the cache to store the last value that was returned, but I am worried that with concurrent calls to the function that it might not work as I expect and 2 calls could get the same integer.
Is cache blocking the correct method to use in this instance or is there something other method I am not thinking about?
Also, stuck using .Net 3.5 and this is a web application.
I just wrote this function based on using SyncLock. Any obvious problems with it that I don't see? I am using the Cache to save the last value that was returned.
Private Shared Function GetNextNumber() As Integer
Dim o As Integer
Dim r As Integer

I don't think I fully understand passing values from a sub to a module. Here is what I'm trying to do (problem is at the '****):

I think I've seen something like this before - where the actual function returns a value. Is this possible? Or would I have to pass an integer variable from the sub to the function, and then return it back to the sub?

coding a shipping application where it adds .75 for every 100.00 dollars it would look something like this
0.00 to 100.00 = .75
100.01 to 200.00 = 1.50
200.01 to 300.00 = 2.25
300.01 to 400.00 = 3.00
and so on where the equaled value goes up .75 everytime i think i could use integer division and/or modulus

I've created a new datasource dtsLogin containing an ID, username and password. my problem is how can you check if the username & password typed in the textbox are the same as the one on the Access database? I thought maybe using a rowfilter but I'm not that good in ADO.net.
