Validate Input Parameters In VB?
Apr 4, 2010Should I validate input parameters on all functions I create? Input isn't passed from a user, but from other routines as part of an automatic process.
I use error handling. I'm not sure what more validating input could do for me. If the input isn't valid, that's pretty much the same thing as an error, isn't it?

[Code]....
I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

Array Is Empty - How To Validate
May 30, 2012I'm working on a program to delete files from a certain folder after they have aged a certain amount of time and either match via regex or extension. I'm running into an issue where files() could be:
files(0) = Nothing
files(1) = Nothing
files(2) = Nothing
etc....
Right now the way it is written, I could place
Else
log(1) = data(1)
log(3) = "Array field empty"
InsertLog(log)
And the program would log as many files as file(i) = Nothing holds. This would create redundant database records and is not wanted. Is there a way to figure out if ALL files(i) = Nothing and then place code in there to insert into the database?
'If log(3) is successful that means no files were old enough or deleted successfully
If log(3) = "Success" And IsArray(files) Then
For Each file In files
If Not file.IsNullOrEmpty(file) Then
'If files is actually something insert into the log
log(1) = file

Forms - What's The Best Way To Validate Items
Mar 28, 2009i created a validation procedure on a textbox_validating event. the procedure goes something like [Code] but somehow it doesn't stop the system from continuing. what happens is on my Save Button where i have. [Code] i'm assuming that when i click the save button, the Textbox1_Validating event is also fired since it also brings up the MessageBox. but then after pressing OK on the MessageBox, it continues to try and Update the DataTable where I get an error from the database saying that the Column does not allow null values.
also when i click Save Button, i noticed that the Textbox1_Validating Event is only fired when the cursor is on that item. basing from this, it seems that the not all Validating Events are fired when an Adapter.Update is executed. what's the best way to validate items? should it be on the Save Button and not on the Validating event of each items?

How To Validate HTML Color
Apr 23, 2012I am extracting color codes from css files using regex and would like to convert them into colours. A few examples of colour codes:
#000;
#669933;
#fff
This is my Regex pattern:
VB.NET
Dim HTMLColor As String = Regex.Match(Input, "#[wd]+?(?=[;
])").Value
To convert the colour I am using:
VB.NET
System.Drawing.ColorTranslator.FromHtml(HTMLColor)
This will throw an exception if the HTMLColor is not a valid "html colour". Because some css colors are not escaped with a ";" I have relaxed my regex a little meaning that it can yield #div as a result for example. I just wondered if there is a way to verify the HTML Colour code before the conversion, without having to use a Try..
