I've been working on my first windows program for a little while and have 2 more things I'd like to do. The program is a simple calculator that could help me with my work. I realize it's a little aggressive for me as I still have lots to learn but would like to finish it. I can live with it, but didn't think the 2 changes I wanted would be too hard until I started searching online. Here is the code for 2 buttons:
Code:private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
int start_cyl = Int32::Parse(textBox1->Text, NumberStyles::HexNumber);
if (start_cyl < 0 || start_cyl > 1048575)
{
MessageBox::Show("Starting Cylinder must between 0 and FFFFF");
}
else
{
int start_head = System::Int32::Parse(textBox2->Text, NumberStyles::HexNumber);
if (start_head < 0 || start_head > 14)
{
MessageBox::Show("The start head must be between 0 and E");
}
else
{
int start_blk = Int32::Parse(textBox3->Text, NumberStyles::HexNumber);
if (start_blk < 0 || start_blk > 127)
{
MessageBox::Show("The start block count must be between 0 and 7F");
}
else
{
int end_cyl = Int32::Parse(textBox4->Text, NumberStyles::HexNumber);
if (end_cyl < 0 || end_cyl > 1048575)
{
MessageBox::Show("End Cylinder must between 0 and FFFFF");
}
else
{
int end_head = System::Int32::Parse(textBox5->Text, NumberStyles::HexNumber);
if (end_head < 0 || end_head > 14)
{
MessageBox::Show("The end head must be between 0 and E");
}
else
{
int end_blk = System::Int32::Parse(textBox6->Text, NumberStyles::HexNumber);
if (end_blk < 0 || end_blk > 127)
{
MessageBox::Show("The end block count must be between 0 and 7F");
}
else
{
int ans = ((start_cyl * 0x80 * 0xf) + (start_head * 0x80)) + start_blk;
int ans1 = ((end_cyl * 0x80 * 0xf) + (end_head * 0x80)) + end_blk;
textBox7->Text = ans.ToString();
textBox8->Text = ans1.ToString();
}
}
}
}
}
}
}
private: System::Void button2_Click(System::Object^ sender, System::EventArgs^ e) {
textBox1->Clear();
textBox2->Clear();
textBox3->Clear();
textBox4->Clear();
textBox5->Clear();
textBox6->Clear();
textBox7->Clear();
textBox8->Clear();
}
};
}
1. I'd like the enter button to default to button one (calculate).
2. I'd like every one of my text boxes to default to 0 if no input.
This is not homework, can anyone help me out?
