Use a queue to generate web addresses with a component dataGridView (Visual C++)

Code class in a separate file:

template <class mainType> class MY

{

private:

System::Int64 start,end,max;

mainType *mT;

public:

MY(System::Int64 value)

{

mT=new mainType[max+1];

start=0;

end=0;

max=value;

}

System::Boolean is_Empty()

{

if(start==end)

return true;

else

return false;

}

System::Int64 order(mainType &value)

{

if(start==end)

return -1;

value=mT[start++];

if(start>max)

start=0;

return 1;

}

System::Void insert(mainType value)

{

mT[end++]=value;

if(end>max)

end=0;

}

};

Main program:

#pragma endregion

private: System::Void Form1_Load(System::Object^  sender, System::EventArgs^  e) {

}

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {

char **tables,*WWW;

tables=new char*[10];

System::Int64 i;

System::Int64 temp_Bool;

for(i=0;i<10;i++)

tables[i]=new char[20];

tables[0]="www.hpe.com";

tables[1]="www.ibm.com";

tables[2]="www.google.com";

tables[3]="www.cnn.com";

tables[4]="www.yahoo.com";

tables[5]="www.nasa.org";

tables[6]="www.microsoft.com";

tables[7]="www.linux.com";

tables[8]="www.embarcadero.com";

tables[9]="www.java.com";

array<System::String^>^ string_Tables=gcnew array<System::String^>(10);

 

MY<char*> FIFO_values(11);

dataGridView1->ColumnCount=1;

dataGridView1->RowCount=10;

 

for(i=0;i<10;i++)

{

FIFO_values.insert(tables[i]);

System::String^ temp=gcnew System::String(tables[i]);

dataGridView1->Rows[i]->Cells[0]->Value=temp;

 

}

for(i=0;i<11;i++)

{

temp_Bool=FIFO_values.order(WWW);

if(temp_Bool==true)

{

System::String^ temp=gcnew System::String(WWW);

listBox1->Items->Add("You can use - "+temp);

}

}

for(i=0;i<10;i++)

delete [] tables[i];

delete [] *tables;

}

private: System::Void dataGridView1_CellContentClick(System::Object^  sender, System::Windows::Forms::DataGridViewCellEventArgs^  e) {

System::String^ myWWW;

myWWW="http:/";

myWWW=safe_cast<DataGridView^>(sender)->CurrentCell->Value->ToString();

System::Diagnostics::Process::Start(myWWW);

}

};

}

I tried to use the structure - array<System::String^>^ tables=gcnew array<System::String^>(10),but for costructor class (new[max+1]) type String^ and array showed errors. So i used - char*.
