Create a class library project in one or the other. Then in the client app. add a reference to it and an import or using statement.

Hi Kevin,
Thank you very much, i think you are right, i can do that. But what if there is a project with a form in VB.net. can i make this form or module as a part of my VC++. net file.
To be very clear, i have one module with a form in VB.net. i want this form to open when i click a button in VC++.net MDI dialog box. Is it possible? i guess not??
What about porting that form into my VC++. net MDI?
Kindly help me, i hope my problem is stated well. if not kindly ask me to be clear.
Thank you.
Kind Regards
Sandy

Hy Sandy,
I faced a similar problem, and find the solution.
In my case, I created a C++ .NET Class Library with Form class and ported to C+++ Builder as an MDI Child.
I absolutly sure, your problem can be solved too.
Some suggestion:
-Create Class library with Form class
-Write a public Interface with CreateForm() method
-Write a public class which expose the Interface; in the CreateForm() method create a Form and call the form Show() method;
-Create a Type Library and register it with regasm.exe
-Add the assembly to the GAC with gacutil.exe
In the Other DEV Environment:
-import type library
-create an instance of the public class
-Call the CreateForm() method and you'll see a form 
To resolve the MDI child problem
-pass the parent handle to the childe + Call SetParent() WinAPI fuction
-set the child window style to MDIShilde with the SetWindowLong() WinAPI fuction
This guideline is bullshit, I know...
You probably dont understand, what I mean... but I tryed.
I guess, there is a simpler solution to your problem, because you stay in the .NET Framework...
If I have some free time, I'll write a tutorial to explain everything...
Till then, don't give up...

Step by step:
In VC++:
1. File > New Project > VC++ > CLR > Class Library
2. Right Click on the project > Add > Class
Select Windows Form
3. Close Solution
In VB:
1. File > New Project > VB > Windows > Windows Application
2. Switch the Form IsMdiContainer property to true
3. Add a MenuStrip to the Form
4. Insert 2 menuitem:
-New VC++ Form
-Window
5. Select the MenuStrip
Set the MdiWindowListItem to WindowToolStripMenuItem
6. In the Solution Explorer right click on the project and Add Referece
Go to the Browse tab and find the VC++ dll
7. In 'New VC++ Form' menuitem click event:
Dim CppForm As Object
CppForm = New VCpp_Form.Form1
CppForm.MdiParent = Me
CppForm.Show()
Other notes:
-It works vice versa. (VB -> VC++)
-It is also possible to port the .NET window to other Dev. Environment,
but if you leave the .NET Framework it is more complicated than the specific example.
Such as I embedded the VC++ Form to the C++ Builder 6, but I'm absolutely sure it works with MFC, VB 6, etc.

Hi All
I have written an xml web service it works fine. My install program also works fine. The problem is that when I try and "edit" the web.config file I do not have the correct security settings on the web.config file. If I change them manually it the program works fine. Now the question. How do I go about setting security settings programmatically in .Net 2
Thanx

Goal:
Create a .NET Form in Visual Studio 2005 (C++) and use it in Borland C++ Builder 6 as MDI Child form.
I read several article in .NET Interop, and I managed to create the .NET form in Builder, but I have not any idea how to resolve the MDI childe problem.
Present source code avialable here:

I resolved the MDI child problem too.
The key is WinAPI

You cannot pass parameters to thread methods in .NET 1.1. There are several workarounds to solve these issues, the one we follow is
<br />
class MyClass<br />
{<br />
private int a;<br />
public int A<br />
{<br />
get{ return a;}<br />
set{a = value;}<br />
} <br />
void show()<br />
{<br />
}<br />
}<br />
<br />
MyClass myObj = new MyClass<br />
myObj.A = 90;<br />
Thread t = new Thread(new ThreadStart(myObj.show));<br />
t.Start();<br />
In .NET 2.0, we have a ParameterizedThreadStart delegate which will allow you to pass parameters to the methods while creating threads.
My small attempt...

Question - How can the profile provider be specified at runtime?
Explanation:
I have two systems, one for 'Test' and one for 'Live' and each has a Sql Server.
When 'Test' code is published to 'Live' I currently have to edit connection strings in web.config to ensure that the live system does not access the test database and vice versa.
This method is prone to error so for Membership and Roles, I have created providers for Test and Live and select the correct provider at runtime. (This is achieved by recognising the machine name of the Test server).
eg
MembershipProvider myMembershipProvider =
Membership.Providers["CustomAspNetSqlMembershipProvider"];
MembershipUser myMember = myMembershipProvider.GetUser(strUsername, true);
However, the same syntax does not seem to be available for Profile.
I need to select the profile provider at runtime, but the defaultProvider is always used.
Extract from Web.config
<profile enabled="true" defaultprovider="CustomAspNetSqlProfileProvider" automaticsaveenabled="true">
<providers>
<clear>
<add name="CustomAspNetSqlProfileProvider" connectionstringname="LiveSqlServer" applicationname="myApp"
="" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<add name="LocalAspNetSqlProfileProvider" connectionstringname="LocalSqlServer" applicationname="myApp"
="" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<properties>
<add name="Firstname">
<add name="Lastname">
<add name="Comments">
The following code creates a ProfileCommon using the default provider
ProfileCommon mProfile = new ProfileCommon();
mProfile.Initialize("myUsername", true);
I would like to use the LocalAspNetSqlProfileProvider on the 'Test' system, and use the CustomAspNetSqlProfileProvider on the 'Live' system.
The following line fails because the 'Live' SQLServer is unavailable from 'Test'
TextBox1.Text = mProfile.Firstname;
How can the profile provider be specified at runtime?

Oops - I didn't realise that xml tags would be stripped. Here's the web config again. 
Extract from Web.config
<profile enabled="true" defaultProvider="CustomAspNetSqlProfileProvider" automaticSaveEnabled="true">
<providers>
<clear />
<add name="CustomAspNetSqlProfileProvider" connectionStringName="LiveSqlServer" applicationName="myApp"
type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add name="LocalAspNetSqlProfileProvider" connectionStringName="LocalSqlServer" applicationName="myApp"
type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</providers>
<properties>
<add name="Firstname"/>
<add name="Lastname"/>
<add name="Comments"/>
</properties>
</profile>
