These are some articles on IJW. The first one is an intro tutorial :-

Hi All,

I have some old Visual C++ code that I think would
work well as a "web service".

Is it difficult to convert my existing VC++ code
to .NET code?

Does that even make sense? Confused | :confused:

Please help!

if i want to use function of vc++

I guess there is no definite answer. I am assuming you would write the web service in Managed C++, so at least some of the code could port over with ease. You would basically just want to rewrite the application from scratch, referencing your existing app. for logical aspects. If your existing code is complex and convoluted then your web service very well could be too. Using Visual Studio.NET will definitely help you in the web service arena.

if i got the hwnd of any process through process class
how will i convert it into HWND type?

I presume you have a Handle which you want to convert to an HWND.

HWND h =(HWND)m_Handle.ToInt32(); //m_Handle is a Handle

IIS required for managed C++ web service.

9-Aug-02 14:19

You don't really need to wrap CSocket. Using IJW you can use your CSocket class straight from MC++ without need for any wrappers. You only need to wrap if you plan to integrate with C# or VB.NET

First off I'm absolutely new to the .NET environment all together.

I recently bought Visual Studio .NET academic. I wrote a small web service in managed C++ but it keeps telling me that I must have IIS installed to run the service. Is there any other way to test this without running IIS? It's not that big a deal I'm just playing around with .NET at home. Just curious.

nay

Can u write ASP.NET pages with MC++?

10-Aug-02 2:22

You can definitely consume a web service without IIS, as to providing a web service I beleive they provide xml/soap messages via http, that is why they are so popular, distributed over a common protocol like http. So you are probably going to need a http server, it doesn't necessarily have to be IIS, I don't think.

Can you use MC++ as your code-behind for ASP.NET page ?

The above would make one beleive MC++ could be used for ASP.NET, the statement may be true, but I guess MS is assuming you will write the plumbing coding for the ASP_RUNTIME to recognize and compile MC++, not sure why they make this statement Confused | :confused:

Thanks.

Web services can definitely be written using MC++, but MC++ does is not supported by ASP.NET.

Chris,
I agree with this statement, ASP.NET does not support a Managed C++ parser, but you can program ASP.NET pages with Managed C++, please see my article
http://www.codeproject.com/useritems/HelloWorldMC.asp[^]

Thanks for your comments. Laugh | :laugh:

I've asked Nick Hodapp, Microsoft's C++ Product Manager to write a note regarding issues involved with using Managed C++ in ASP.NET. It *seems* like it works but there are some "gotcha's" that mean it's not advisable.

Yes, there is.
You can use DirectShow.

Complex Numbers

I am having a few problems with the following code:

int main(){

double a, b, c, d;

cout << "Enter the first complex number:";
cin >> a >> b;
cout << "Enter the second complex number: ";
cin >> c >> d;

cout << "(" << a << "+" << b <<"i)" << " + (" << c << d << "i) = ";
cout << Sum(a,b,c,d)<< endl;

return 0;

}

double Sum(double& a, double& b, double& c, double& d){
double i;
double sum1, sum2;
sum1 = (a + c);
sum2 = i*(b + d);

return (sum1 + sum2);
}

When go to print the function to the screen will not display (7-i) but instead prints the value 7. How do I get around this problem? Confused | :confused:

Because u didn't identify i the output has some errs.Do not identify i by using double,identify it like characters.And finnaly add it to answer.
cout<<(a+c)+(b+d)<<".i"; like this .ok??
However if u want to make some other calculations on complex number theory , you have to identify the special properties of i.
