Hi, I am using Windows media player in my project, if I call media player from my main form its playing, I have written code that when I click Wmp it goes to main form but when I do this it is showing "Attempted to read or write protected memory. This is often an indication that other memory is Corrupt". Can anyone provide solution for this, Thanks in advance .



Mainform code:

Frmads frm=new frmads(this);
Frm.show();
This.hide();

Ads Form code:

If(e.newstate = =2)
{
Frmmain.Activate();
Frmmain.show();
This.close();
}
