Utf 8 - Function That Will Tell Us Whether 2 Strings Are Equivalent Under UTF8 Unicode Collation?
May 23, 2012
This question is similar to How to emulate MySQLs utf8_general_ci collation in PHP string comparisons but I want the function for vb.net rather than PhP.Recently I make a lot of supposedly unique key.Some of the keys are equivalent under UTF8 unicode collation.For example, look at these 2 key:
byers-street-bistro_38.15-79.07
byers-street-bistro_38.15-79.07
If I paste that into front page, and look at the source code you'll see
byers-street-bistro__38.15_-79.07
byers-street-bistro__38.15_-79.07
Note: In stack overflow they still look different.I know it's not the same. I guess even in stack exchange it doesn't show. Say I have 1 million such records and I want to test whether 2 string WILL be declared the same by MySQL UTF8 collation. I want to know that before uploading. How do I do that.So vb.net think that those are different keys. When we created mysql query and upload that to database, the database complain it's the same key. Just one complain and the upload of 1 million databases will be stuck.We don't even know what the hell is ? Where can we look that up anyway?Anyway, I want a function that when given 2 strings will tell me whether they will count as the same or not.If possible we want a function that convert strings into their most "standard" form.For example, seems to encode nothing and the function would recoqnize all those nothing character and eliminate that.Is there such thing?So far this is what I do. I need something more comprehensive.

I have to turn strings into Unicode. I thought the best way to do this would be as followed
HTML
For...Next to get the string
For...Next to take each character out of the string
For...Next to display each character in Unicode
The only problem I have is with the separation on each character in the string. I know I have to use a For...Next loop to check each spot in the string. But how would I move on past the first character?

After checking an Xps file i noticed that the string within the Xps file <> is converted to <>So is there any built-in function in the .Net framework that could do this job for me?If it does not exist what characters becides <> should i escape in myOwn function?
I try to implement a search within an xps file, but searching for <> instead of <> returns nothing.
UPDATE: At least i found the list here of xml document escape characters

VB has a function InputBox() that will prompt the user to enter a single value, then click OK. Is there a parallel functionality in ASP.NET, that will get the browser to pop up some kind of input box to return a single value? If not, how do you recommend I achieve this effect?

In Access if a query were to compute the sum of different fields where there is a likelihood of one or more fields being NULL, you use something like NZ. Is there any equivalent Function for handling NULLs in VB .NET?
I'm use the code below to retrieve the SUM of the column "BudgetAmt" from my DB but get InvalidCast Exception was unhandled error because the BudgetAmt and/or AllocationPersonnel holds no data:
Dim strSbCode As String = cboSubSubOrg.SelectedValue.ToString
Dim budgetYr As Integer = CInt(cboBudgetYr.Text)
personBudget = CDec(transDetailsDT.Compute("SUM(BudgetAmt)", "FundSource = '02101' AND DataSource = 3" _

I'd like to know if something like this pseudo code:
myVar = "functionName"
call someObject.(myVar evaluation)
which would then be equivalent to:
call someObject.functionName
is possible in VB. I know this is done in some other languages using a GetProperty method.

As a non .net programmer I'm looking for the .net equivalent of the old vb function left(string, length). It was lazy in that it worked for any length string. As expected, left("foobar", 3) = "foo" while, most helpfully, left("f", 3) = "f".
In .net string.Substring(index, length) throws exceptions for everything out of range. In Java I always had the Apache-Commons lang.StringUtils handy. In Google I don't get very far searching for string functions.
Edit:@Noldorin - My first encounter, although it took me several seconds to do the same in c#:
[Code]...
Note the static class and method as well as the this keyword. Yes, they are as simple to invoke as "foobar".Left(3). See also c# extensions on msdn.

I have an Excel VBA function that takes a number of optional parameters, including an optional Range:
Function DazBeta(A As Range, Z As Range, _
B As Integer, _
Optional Freq As Integer = 1, _
Optional c As Double = 0, _
Optional r As Range, _
Optional Pct As Boolean = True, _
Optional Label As Integer = 1)
I am translating to VB.NET, and it's the optional Range that is giving me grief because VB.NET does allow optional Ranges. Or rather, optional parameters must provide a default value. What is the recommended way to change the VB.NET function signature so that the code is callable from an Excel cell as a UDF? (The VB.NET implements a UDF, the assembly is registered as a COM server, and the Excel spreadsheet is told of this server and type library, allowing the VB.NET code to be called from an Excel spreadsheet cell.) I have other compilation problems, so I have not been able to explore this. I am thinking that accepting an optional Object (default value Nothing) might work and then I could cast the Object to a Range. Alternatively, if there were a default value that could be specified with an optional Range, that would work, too.

Basically, I'm trying to do some string manipulation to edit directories. I found some code to try and edit the directories, but when I use it it doesn't recognise 'right' as being a function and only recognises it as a right property, thus producing an error.
I was wondering if there's something I haven't imported or if perhaps 'right' is an obsolete function that was used in VB6 but replaced with something. The code I have is as follows:

Update: I didn't make it clear but I meant this to be a question about where/how I would use a function to return a list of strings when I'm trying to just work with classes.I have a class called Account.
I have data access class called AccountDAO.I have various functions that return lists of objects like GetAllAccounts, GetAccountByID etc.I want to populate a drop down list with just the account names and nothing else. It's proving rather slow when using lists of objects and databinding them to the dropdownlist.
I feel like I should be using a simple "Select Account_Name From blah" type statement and returning a list of strings but I don't know how to work this into my class and data access class.
