Hi amirsamanipoor,
>> i want my form be disapeared when user want to capture my screen with screen capture program
I am not sure how do you achieve that your form be disappeared when user want to capture my screen. If you want the form disappear in the screen, I think you could try the code below:
private void Form1_Load(object sender, EventArgs e)
this.TransparencyKey = this.BackColor;
>> totally how can i prevent user capture my screen or winform with screen capture program?
What do you mean by this? Do you mean you want to prevent the user to capture your screen from the winform? Based on your description, you capture your screen with “debut video capture” which is a third party product. I am afraid you could not. If this issue
is a second issue, I will recommend you post a new thread for this issue.
The reason why I suggested is:
#1 There would be more community members to discuss the question.
#2 For people who have the similar question, it would be easier for them to find the answer from a specific thread.
Thanks for your understanding.
Best Regards,
Edward
