is there an easy way to add mp3 playback, like a looping mp3 that plays throughout the life of the application

Yes, there is.
You can use DirectShow.

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?

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.

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();

Hi,
I had posted this earlier here, but got no response.
I am trying my luck again (by changing the Subject Line...;))
I have a User Control (created using Man C++)
When I try to place this Control on a form, the Form Designer throws an Exception( 0x80131019).
And I am not allowed to place the control on the form.
This happens when the CopyLocal Property of the Reference is True.
But if I change the CopyLocal property to False,
the Designer wholeheartedly accepts the Conrtrol.
The Form Designer doesnt behave this way with controls made using C# or VB.Net.
Can someone please tell me what difference does CopyLocal property
make to the Form Designer ?
Why does this happen only with Controls created in Managed Cpp?
My control does nothing extraordinary, but just some Drawings in the OnPaint().
Please, somebody Help me.....
Thanks,
Firoz

Your assembly needs to be registered in the GAC. To do this it first needs a "strong name", sort of like a GUID.
Use SN.exe to generate a strong-name key file. In your AssemblyInfo.cpp file, specify the key file as a parameter to the AssemblyKeyFileAttribute() attribute. Rebuild your assembly.
Now use Gacutil.exe to register the assembly in the GAC. This step can be done in a custom-build-step if desired.

Hey coders....
Okay I am just trying to create an instance from HWND and it won't let me.
ie.
<br />
using namespace System;<br />
#using <mscorlib.dll> <br />
<br />
public _gc class COO<br />
{<br />
HWND m_hwnd;<br />
public:<br />
COO(HWND hwnd)<br />
:m_hwnd(hwnd)<br />
{}<br />
};
When I hover over HWND it gives me (typedef HWND__ *HND) so I assume it is recognizing it but for some reason I can't use it....
If anyone could tell me why and how to get around this it would be much appreciated. Thanks...
