  • VB.net: Custom ' TODO: List on an Interface

    - by Shiftbit
    How do I add my own todo and comments list to appear on Interfaces? I want it to pop up like IDisposable does: Public Class Foo : Implements IDisposable Private disposedValue As Boolean = False ' To detect redundant calls ' IDisposable Protected Overridable Sub Dispose(ByVal disposing As Boolean) If Not Me.disposedValue Then If disposing Then ' TODO: free other state (managed objects). End If ' TODO: free your own state (unmanaged objects). ' TODO: set large fields to null. End If Me.disposedValue = True End Sub #Region " IDisposable Support " ' This code added by Visual Basic to correctly implement the disposable pattern. Public Sub Dispose() Implements IDisposable.Dispose ' Do not change this code. Put cleanup code in Dispose(ByVal disposing As Boolean) above. Dispose(True) GC.SuppressFinalize(Me) End Sub #End Region End Class Whenever I enter my own comments and todo list they are never autogenerated like IDisposable Interface does. I would like my own Interfaces to preserve the comments so that I can share my Interfaces with in source documentation.

  • Undetermined type conversion in VB.NET 2008

    - by user337501
    I figured this would be a quick google, but extensive searching hasnt yielded any results. Everything about type conversion seems to dance around this concept. I want to get the type of variable "a", and make a new variable named "b" of that type. Otherwise I could have "a" as a type already declared and "b" simply as an Object, then try to cast "b" to the type of "a". Dim a As Integer Dim b As Whatever a Is OR TryCast(b, Whatever a Is) I would also like to make the conversion using a variable representation of the type, but cant find info on how to do that either. Sorta like: Dim a As Integer Dim b As Object Dim t As Type t = a.GetType() TryCast(b, t) Realizing I'm completely misusing TryCast here, I'm mostly trying to get my goal across. I figured it would be an easy quick thing to do but I cant really find any specific info on it. Any ideas?

  • urlrewriter.net page not executed

    - by peter
    Hello, I'm having some problems with the module urlrewriter.net for ASP.NET. I have a multilingual site with a URL like this; ~/home.aspx To support languages I use this rewrite rule; <rewrite url="~/de-DE/(.*)" to="~/$1"></rewrite> Then in my code I get the de-DE part and set the right culture for the current thread. All of this works well. After I login on the website I get a message "Hello, user x" to show i'm logged in. When navigating to another page, it doesn't display this message anymore and it seems like the page comes from the cache or something with the old (not logged in) data. Also, when I attach the debugger, nothing is executed for this request. If I visit the page like ~/home.aspx instead of ~/de-DE/home.aspx, does problem does not occur. What could be the problem here? Thanks

  • VB.NET - Find a Substring in an ArrayList, StringCollection or List(Of String)

    - by CJM
    I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'. I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc.... I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way. Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either. Any suggestions? Or should I just iterated through the list of groups?

  • error in mysql syntax in vb.net

    - by user225269
    I get this error, while I'm testing the code below: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '[student](ID, LASTNAME, FIRSTNAME, SCHOOL) VALUES ('333', 'aaa', 'aaa', 'aaa')' at line 1 I just recycled the code that I used in manipulating ms sql database.

  • What is the equivalent to Master Views from ASP.NET in PHP?

    - by KingNestor
    I'm used to working in ASP.NET / ASP.NET MVC and now for class I have to make a PHP website. What is the equivalent to Master Views from ASP.NET in the PHP world? Ideally I would like to be able to define a page layout with something like: Master.php <html> <head> <title>My WebSite</title> <?php headcontent?> </head> <body> <?php bodycontent?> </body> </html> and then have my other PHP pages inherit from Master, so I can insert into those predefined places. Is this possible in PHP? Right now I have the top half of my page defined as "Header.html" and the bottom half is "footer.html" and I include_once both of them on each page I create. However, this isn't ideal for when I want to be able to insert into multiple places on my master page such as being able to insert content into the head. Can someone skilled in PHP point me in the right direction?

  • VB.Net List.Find. Pass values to predicate

    - by Beta033
    Having a bit of trouble using the List.Find with a custom predicate i have a function that does this private function test () Dim test As Integer = keys.Find(AddressOf FindByOldKeyAndName).NewKey here's the function for the predicate Private Shared Function FindByOldKeyAndName(ByVal k As KeyObj) As Boolean If k.OldKey = currentKey.OldKey And k.KeyName = currentKey.KeyName Then Return True Else Return False End If End Function by doing it this way means i have to have a shared "currentKey" object in the class, and i know there has to be a way to pass in the values i'm interested in of CurrentKey (namely, keyname, and oldkey) ideally i'd like to call it by something like keys.Find(AddressOf FindByOldKeyAndName(Name,OldVal)) however when i do this i get compiler errors. How do i call this method and pass in the values?

    Anyone experience any issues with IIS7, integrated mode forms authentication while using IE8? I have a website with a login form, once logged in, any postback causes the user to be logged out.

I can not replicate the problem in any other browser and I cannot replicate on my development machine running / debugging vs2010.
