I have this and I want to use something similar to the way Java uses .class files to be able to call events and use them in my main code.
The problem is that I cannot get the .class file to use my Dims
Form1.vb:
Namespace LFS_External_Client
Public Class Form1
Inherits Form
[Code]....
Code was shortened but has all of the relevant and necessary parts.
I always used to define variables like Dim xxxx As yyyyy. In the tutorials I'm looking at though they do Private Const xxxxx As yyyyy. I wonder just what is the difference here? What is the significance of this change? What am I actually doing with 'Dim' and what is this Private Const doing different?

Imports Microsoft.VisualBasic

Public Class ClientProfile
#Region "Variables"
[CODE]...
It is in the file ClientProfile I have placed in both App_Code and also App_Code/Models
In my code behind I have the following

The last word, "ClientProfile" has the scary squiggly red line below it. It is not recognizing my class.Even the Intellisense is not picking up te class. Do I have to register the class file in any way?
Example:
Two files - TestClass.vb, myForm.vb
TestClass.vb looks as follows:
Imports System.Threading
Public Class TestClass
Private myClassThread As New Thread(AddressOf StartMyClassThread)
[code]....
The result:Application runs, no errors or exceptions.Displayed is the listbox and the Start button.I press the start button and a msgbox says "Not Invoked" as expected and upon clicking OK to that msgbox "Start Button Pressed" is added to the Output listbox control.Immediately following that the msgbox pops up again and says "Not Invoked". I was expecting "Invoked" as a separate thread is trying to use the Output listbox control.Of course this results in the Output.Items.Add being attempted which results in no visible result as the thread is not allowed to directly update the UI control.
so I used to mess around with C#, just a little. And someone had helped me make a class for Visual C# that was supposed to do the math parts for "internal structure" - which the program used for a part of its calculations and screen... Basically there were 2 options. Endo-Steel and Standard. The user would use a updownbox to determine weight of the machine and then internal structure was a % of that total. If it was standard then it was 10% of the overall weight, if it was Endo-Steel then it was 50% of standard (so 5% of total weight) rounded to next 0.5 (so .25 was .5, 1.25 was 1.5, 1.75 was 2.0, etc). I have the code for the C# class file for it, but want to make it in VB.

I'm having a problem with a class issue in VB 2005. The error message reads "The class Tellerform can be designed, but is not the first class in the file. Visual Studio requires that you use the first class in the file. Move the class code so that it is the first class in the file and try reloading the designer again."

I create a project using query sql ( Select, Update,Delete,Insert ) in many various way. example by Select with condition ..etc someone work in programing field. tell me that you are not profession in using vb.net , because you have to use OOP instead all of these Sql query. because if you want to make any update on your program after start to work on the Pc you will open your project on design and change the code. but in OOP you will make update on class and then put it as DLL file in the file of program.

OK I am as green as they come and just want to write a simple app that when it starts loads data into a few fields from the previous use.
I am thinking of using an XML file written to disk to hold this info, (I am open to any suggestions how to do this as simple as possible)
so I am going through the "Wrox VB2010 for beginners" and entering the code to create a class and apparently the compiler doesnt like something about saving stream as a string: It says "Value of type 'System.IO.FileStream' cannot be converted to 'String"

Does this mean that the type is not set up correctly?If you're not living on the edge, you're taking up too much room

View 1 RepliesGot a solution with 3 projects, a Web Service, a WinForms (MyUI), and a Class Library (Foo).
MyUI calls methods in the DLL that access the web service. The DLL has project config settings that store the URL of the web service. I compile the solution and it compiles all 3 projects. In the DLL's bin dir it puts the foo.dll and foo.dll.config files. However, in the WinForms bin dir it puts the MyUI.exe, MyUI.exe.config, and foo.dll; it doesn't include the foo.dll.config. When I run the MyUI.exe from its bin dir, it appears to work, and is obviously getting the config settings from somewhere because it doesn't crash and successfully contacts the web service. However, if I copy the foo.dll.config file into the MyUI's bin dir, and change config settings and re-run, it appears to ignore my changes completely.
In the Class Library I setup the config settings through the project properties dialog under the Settings tab. I access them from code using My.Settings.
How do I modify the config settings post-compile?

When I prototype I tend to keep all my classes in one file (bad practice I know, but yeah it a prototype). Then comes the point the where the files is too hard to navigate. So I breakout the classes into separate files inside the project, the folder structure reflecting the namespaces.To achieve the is;- 1. Add new Folder 2. Add new Class 3. Name class 4. Cut and paste corresponding section into new class file.For me, Steps 2 through 4 are prime fodder for a new Menu entries.
