To achieve this you can handle the KeyDown event for your form or button and check for specific key presses. Here's an example of how you can integrate the DialogResult with the KeyDown event: Handle the KeyDown event : Attach an event handler to the KeyDown event of your form or button. Check for specific keys : In the event handler check if the pressed key matches the desired keys (e.g. NumPad1  NumPad2  NumPad3 ). Here's a sample code snippet to demonstrate this: // Assuming you have a button named 'submitButton' submitButton.KeyDown += new KeyEventHandler(submitButton_KeyDown); private void submitButton_KeyDown(object sender KeyEventArgs e) { if (e.KeyCode == Keys.NumPad1) { label2.Text = You have purchased the software congratulations; } else if (e.KeyCode == Keys.NumPad2) { label2.Text = Option 2 selected; } else if (e.KeyCode == Keys.NumPad3) { label2.Text = Option 3 selected; } } // Method to show the dialog and handle the result private void ShowDialogAndHandleResult() { DialogResult dr = MessageBox.Show(Do you want to purchase the software? Purchase Confirmation MessageBoxButtons.YesNo); if (dr == DialogResult.Yes) { label2.Text = You have purchased the software congratulations; } else if (dr == DialogResult.No) { label2.Text = Purchase cancelled; } } // Call this method when the submit button is clicked private void submitButton_Click(object sender EventArgs e) { ShowDialogAndHandleResult(); } In this example: The submitButton_KeyDown method handles the KeyDown event and updates the label based on the key pressed. The ShowDialogAndHandleResult method shows a dialog box and updates the label based on the dialog result. The submitButton_Click method calls the dialog method when the button is clicked. This way you can handle both the dialog result and key presses to update the label accordingly. Thanks

To hanlde Key even/Key Down event in a Windows Forms application and use them to interact with a message dialog box you can handle the KeyDown event of the form or the specific control you want to capture the key presses from. Here's a simple example to guide you: Show the Dialog Box : When the submit button is clicked show the dialog box. Handle KeyDown Event : Capture the key presses in the form. Here’s a sample code snippet to illustrate this: \/\/ Assuming you have a button to show the dialog private void btnSubmit_Click(object sender EventArgs e) { \/\/ Show your message dialog box DialogResult dr = MessageBox.Show(\Do you want to purchase the software?\ \Purchase Confirmation\ MessageBoxButtons.YesNo); \/\/ Handle the dialog result if (dr == DialogResult.Yes) { label2.Text = \You have purchased the software congratulations!\; } } \/\/ Handle the KeyDown event for the form private void YourForm_KeyDown(object sender KeyEventArgs e) { if (e.KeyCode == Keys.NumPad1) { label2.Text = \You have purchased the software congratulations!\; } else if (e.KeyCode == Keys.NumPad2) { label2.Text = \You have selected an alternative option.\; } \/\/ Add more conditions as needed for other keys } \/\/ Don't forget to set the KeyPreview property to true private void YourForm_Load(object sender EventArgs e) { this.KeyPreview = true; \/\/ This ensures that the form receives key events before they are sent to the control }
