[Maxgui] Prevent Screencapturing?
BlitzMax Forums/MaxGUI Module/[Maxgui] Prevent Screencapturing?
| ||
| Hi! Is there a way to prevent a user to press "print" on the keyboard, so he can copy and paste the screenshot out so easily. I'm just looking for a way to protect my media a bit... :o) Thanks, Grisu |

| poll to see if the print key is pressed and then clear the system clipboard if it is |
| ||
| Erm, impossible! Plain and simply :) Even if you disable the print screen functionality there's always programs such as fraps will allow you to capture pics and movies of your game. |
| ||
| Yep, impossible. If your media is that valuable, just don't include it. |
| ||
| You can disable PrintScreen key, however some capturer like HyperSnap can use alternative keys and capture DX/DVD surface, almost impossible to prevent it. |
| ||
| Not to mention the option to capture the screen in regular intervals, like for example in Paint Shop Pro. I am afraid once you have your media displayed on the screen there's no way to protect it. Barney |

| Not to also mention closing off common window functions/keyboard-shortcuts really, really, ticks off a specific group of users like I. |
| ||
| Thanks for the help everyone. I just have noticed that we gui guys have our own forum. So my response is that late... :( |

| My DVD drive won't let me capture the screen. |

| Leadwerks: Your DVD drive renders the video using overlays. I don't know how you use them in a program, but basically the program draws a pink color and then the video card shows the video at the right location without actually putting the video into the screen buffer. So it's like one buffer overlaid over another with a green screen to tell where the second buffer should appear. And this second buffer will show through wherever any program displays that pink color. |
| ||
| Disabling hardware acceleration let's you grab dvd/video frames. As sswift points out it's drawn entirely in hardware on top of the rest of the graphics, it never enters the 'real' screen buffer, if hardware acceleration is enabled. |
| ||
| Fraps can also rip frames from DVD, I have done this frequently. Unfortunately anything that boots on a PC is NOT safe. |
| ||
| Actualy, there is a way of making the media safe even from a screen capture. You just never release the game. If it's installed on your disk (on a machine not connected to the web) only than the greedy public can't get it, no matter what they do. Right? Whoever steals the media by screencapture will most likely never release anything, anyway... Barney |
