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.

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.

One option is to write an __gc wrapper for the unmanaged code

Hi Nish,

I am new to programming and have never
heard of a __gc wrapper?

Could you tell how I can find out more about
__gc wrappers?

Thanks

Nish Nishant9-Aug-02 14:15

See this article :-

for an example of __gc wrappers.

You don't need to wrap CSocket. Here is how you can use CSocket in an MC++ application using IJW

AfxSocketInit();
CSocket s;
s.Create();
String* cmd = "GET /\r\n\r\n";
String* url = "www.google.com";
if(s.Connect((CString)url,80))
{
s.Send((CString)cmd,cmd->Length);
char buf[127];
while(int n = s.Receive(buf,128))
{
buf[n]=0;
System::Console::WriteLine(buf);
}
}
s.Close();
