Importing Class From Bin File Asp.net Virtual Directory
Jul 4, 2011
the problem i met is that i have iis 7 running on my pc.in the root file, wwwroot, i have a website folder, namely [apex] which is a virtual directory. in the folder is a bin folder containing a compiled class with namespace.then in an aspx file, i tried to import the namespace and use the class inside the namespace.
[code]...
the namespace and classname has been checked well, no mistake. but at compiling stage, i got "type is not defined " message. ok,then, in iis 7 control panel, i convert the whole website folder from "virtual directory" to "application" type. the problem goes away!

A little while ago, I managed to get WebServices to return JSON as well as XML from the code-behind of an ASPX.
Today, I needed to migrate an existing ASMX WebService to return JSON instead of XML (which was accomplished with little fuss). My problem became evident in testing the new method.
In the code-behind for the ASMX, I created a new method to return JSON instead of XML. The method works, in that it returns the expected JSON however the new routine breaks every XML-returning method in the code-behind (they all throw "System.NotSupportedException: The type System.Collections.Hashtable is not supported because it implements IDictionary." which is unexpected because the return types are all defined as XmlDocument).
If I simply comment out the JSON-returning method, the XML-returning methods function normally. Uncommenting out the JSON-returning method breaks the XML-returning methods again.
While I cannot find any supporting documentation anywhere, this behavior leads me to believe that in ASP.Net 2.0, JSON-returning methods cannot co-exist in the same module as XML-returning methods.
This led me to try separating the methods in sub-classes like so:
<WebService(Namespace:="http://tempura.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ScriptService()> _

I'm trying to write an application that will allow a non-administrator user to create virtual directories in IIS6. I've tried numerous different ways of impersonating a administrative account but nothing seems to work to create the virtual directory.
Here's some of what I've tried:
dim sDirPath as string = "IIS://remotehost/W3svc/1/root"
Dim de As DirectoryEntry = New DirectoryEntry()
de.Path = sDirPath
de.AuthenticationType = AuthenticationTypes.Secure
de.Username = tbxUsername.Text
[Code] .....
what is the correct way to impersonate another user in winforms application that will allow me to create the virtual directory without the user that's running the application being an administrator on the web server? I know this can be done, IIS manager allows you to use "connect as" checkbox to do it.

Ok, I've been fighting this for days and so far haven't found very much helpful information on the web. Apparently this isn't a very popular thing to do since there isn't much out there. I'm hoping someone here can help me out. I don't know very much about dll's or implementing classes in vb, so please correct me if my thinking is wrong.If it's relavent I'm using Visual Studio 2010.I'm working on a much larger project, so I've created a greatly simplified version to test and and ask questions about.Here's the situation:I've created a class in c++ that I now need to create an interface for in vb. As I said before I've created a much simpler class and compiled it as a dll. There are two functions in the dll:
[code]...
The setTestVar function simply sets the value of a member variable, and getTestVar returns the value of that variable. I load the setTestVar function from the dll like this:
[code]...
Then when I click a button, I call:setTestVar(9) This results in an "AccessViolationException was unhandled" error. "Attempted to read or write protected memory...."After thinking about it, I guess this would make sense if the constructor in the dll was never called (and thus the variable into which I'm trying to store data doesn't exist).So the question becomes, how do I call the constructor in the dll from vb such that I have some sort of handle or reference to that object when the call returns from the dll? Without a handle, I won't be able to access any of the member variables. Is this thinking close to being correct? Or is the problem something entirely different?So again, how do I call the constructor in the dll (from vb) and somehow have access (from vb) to the object that it creates?

I've a requirement to have PreCompiled webpages and Non-PreCompiled webpages under same application. For example below is my structure:
/Bin
/Test1 (PreCompiled)
/Test2 (NonPreCompiled)
/Test3 (PreCompiled)
I would like these to have their separate "Bin" folders too if possible at all (I tried using "Probing" but I guess that's not allowed for web apps and defaults to "Bin" folder). If not that then definitely some ability for these to work together under one app/virtual directory because I'm not allowed to create another at any cost :(

We have a typelib where we define some constants. One of our sets of constants is created using the module keyword:
module MyConstants
{
const int Const1 = 1;
};
I use tlbimp.exe in a bat file to generate a primary interop assembly for internal use.If I create a VB .net project and add a reference and browse to the .tlb file and import it, the result I see in the browser window is a class named MyConstants. If I click the class, the right hand pane is empty - the class contains absolutely nothing.
If I add a reference to the primary interop assembly, I also see the class MyConstants int he browser window. When I click the class, the constants show up.This is in Visual Studio 2010 (RTM). Why does VB .NET add reference via brwose to the .tlb file differ in this case? Is this a bug in VB .NET or the tlbimp.exe tool?

Here is what I have in my file
Option Strict On
Imports MyNameSpace.MyEnum
Public Class AwesomeClass
[Code].....
But since MyEnum isn't defined in the subclass it won't work. I am not very familiar with what these types of things are called, but I think that I am import a type definition of sorts. Since I am Importing, and not defining, it is only available in the first file. Basically, I want to include MyEnum as part of the class but I don't how to do it. I don't want to copy/paste it over, and I don't really want to write Imports ... at the top of all of my subclasses.

I've been trying to find a Windows API function I can use to generate a virtual file handle in Windows.

I have a datagridview on my form with 7 columns and a variable number of rows.

Here's the code I'm using the save the file:
VB.NET

I've gotten this to work fine; however, I'm having trouble with two features I want to implement.The first feature is to be able to save what I play in a text file. I thought I could use this code but I'm getting an error. [code] The second feature is to play random keys using the random class. Is there any way I could store the pictureboxes in an array and then use the random class?

I have inherited a VB.net web app that I'm making some changes on. I'm perfectly capable with the programming side (VB and MSSQL) but I'm getting lost with the tools. I was given a zip file of the code and everything. I opened the sln file in Visual Studio 2005 and it worked fairly easily with little modification.
Running the app works perfectly. Problem is, I need to write some new SPs so need the database admin. SQL Server 2008 Express is installed but it doesn't see any database and I have no idea how to import it.I have a folder App_Data in the project with the file ASPNETDB.MDF. Opening this in VS gived the error: This server version is not supported. You must have Microsoft SQL Server 2005 Beta 2 or later.
