Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
Here's my call:

function HelloWorld()

Call A Dynamic Compiled Func(of ) Function Via Expression.Call?
Mar 22, 2012I want to create an ExpressionTree where a Func(of Vector, Vector, Vector, Vector, Double, Double, Vektor) should be called. So I use
Expression.Call(Forces(0).Function.Method, {Vec1, Vec2, Vec3, Vec4, Double1, Double2})(Vec1-4, Double1-2 are declared as ParameterExpression and Forces(0).Function as Func(of Vector, Vector, Vector, Vector, Double, Double, Vector).

Call A Function From Inside Another And Suspend It Until The Called Function Is Finished
Jan 25, 2010How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

Threaded Function Call Slower Than Calling Function Directly?
Sep 14, 2010I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?
VS 2008 Call KeyUp Event From MouseUp Event For A Textbox?
Aug 16, 2010In VB6 we had a code inside textBox_MouseUp to call textBox_KeyUp(-1, 0) and the signature of KeyUp was
Private Sub textBox_KeyUp(ByRef KeyCode As Short, ByRef Shift As Short) Handles textBox.KeyUp
Now when I migrate to .NET I changed the KeyUp event to Private Sub textBox_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles textBox.KeyUp
How can I do this call textBox_KeyUp(-1,0) now from textBox_MouseUp event?

Sep 6, 2010I am attempting to inherit an ASP.NET RegularExpressionValidator and add some functionality to it. I inherited the control and added my custom properties. However, I would also like the client-side functionality to call a different JavaScript function.
In order to do that, I will need to supress what is happening in the AddAttributesToRender method because the name of the function is hard-coded there. Here is what comes up in Reflector for the AddAttributesToRender function in RegularExpressionValidator:

Note: I tried to add the expando property before the parent class does to see if the code would check for its existence and skip it, but that just causes an exception.

View 2 RepliesCall A DLL Function?
Nov 28, 2010I have created a new Class Library in visual basic and called it 'TestDLL'. I have a TestDLL.vb file where I put in this code
Class TestDLL
Function ReturnHello() As String
Return "Hello"
End Function
End Class
Then I clicked on the build tab and built the solution. I then copied the DLL 'TestDLL.dll' to C:TestDLL.dll
I am trying to use that DLL in a console application. I have tried this code but I get an error: System.EntryPointNotFoundException was unhandled Message=Unable to find an entry point named 'ReturnHello' in DLL 'C:TestDLL.dll'.
Declare Function ReturnHello Lib "C:TestDLL.dll" () As String I have added TestDLL.dll to the references for the console application and got that to work, however my goal is to load and unload different .dll files without restarting the application. I have a lot more code besides this, but I'm just trying to find out what commands I could use for just calling functions from DLL files.
There was something I was reading about assemblies, but all I get that to do is list the classes in my dll file. I will already know all the names and locations of the .dll files, and also the class and functions that they contain, because I will be building all of them. how I can get a simple function return in my console application.
