I'm using the 2D graphics engine of Visual Basic. The graphics are fine for my purposes, however they erase when they move out of sight.I was looking at the System.Drawing.Graphics properties, and came across a save funtion, however that did not prevent the erasing.How do I prevent this from happening?

How can i make variables stay true even after i close my program so on next run there still true?Heres the Code i am using to set the variable (if it helps) :

Dim Activated As Boolean
If Activated = True Then

BTW this is to check if the product has been activated or not.
Am writing a graphics program which will develop components and save them to files for later retrieval.Cant Figure out how to save the color component of the graphics to the file.The File seems to accept only string items and I have not been able to figure out how to convert the color string back to a color object.

As some of you may know, school is coming to close for summer recess, and final projects are coming up. My Computer Science teacher has asigned us an animation project. Basicly, all we have to do is make a game where we make a picturebox move using the arrow keys and it flips to face the direction its going in. This is a little easy for me, and i really want to go above and beyond and make my final project my best. So instead of little 2-D picture boxes moving choppily across the screen, can i push visual basic's limits and make a 3-D representation of a character in my game and use that with the arrow keys?
View 7 Replieswhat I mean, every full-featured program has one. Tools > Options brings it up in Firefox. First off, I've looked for tutorials on making these and can't find them anywhere, does anybody have any links? Second, I'm making mine with a TreeView and panels. The problem is designing this thing with all of these overlapping panels! It's crazy. So, how do you easily make an options menu like Firefox where clicking on different tabs brings up different data options?

View 11 Repliesmaking a screen recorder. make it take a screenshot 15-30 times a second, and for each shot there will be a text file that will say the location of the cursor when the shot was taken and what the cursor was, like loading or whatever. Then when the user presses save, it will take all the shots, import the cursor in each one and then create an AVI using each of the frames that were initially shot. Another better way would be to take a screenshot with the cursor in it, if thats possible.

Here is a picture of my program running: How do I stop everything being deleted when things pass it...? how can i add a save feature to this program?
I'm a VB beginner.I've been playing with Graphics.DrawString by watermarking a picture with a text string. The picture below to the left comes from PictureBox with a text string drawn with Graphics.DrawString. The font style used is Arial 48 points, regular, I think. The picture in PictureBox shows just as I configure. Great... The resolution of the original Terri Hatcher picture is 300 dpi (300 x 300). Exporting this picture with Graphics.DrawString, I get the picture below to the right. The text string appears a lot bigger than previously shown in PictureBox. It turns out that the text size varies, depending on the resolution of the original picture. That's kind of odd. I develop several graphics applications in a different environment and have never seen this sort of graphics.drawstring thing. Anyway,
my sample application seems to draw a text string at an image resolution of

View 4 RepliesWe have a GIS application that has some performance issues. It creates and sends an image to a web browser. We start with a Bing Maps imager, add complex polygons (complete with transparent fill), save the finished image as a PNG, and send it to the browser.
The idea has come up that we could possibly install a graphics card and use DirectX or OpenGL to improve performance. I believe this would be the case even though we ultimately generate an image instead of sending the data the the screen. I believe our processes could still make use of the API and the hardware acceleration it provides. Our process is not unlike what CGI film makers do to render individuals frames of a film, though we simply render a single image and send it, as opposed to the hundreds of thousands of images needed for a single CGI film.
So my question is: would a powerful graphics card and use of DirectDraw or OpenGL provide us a worthwhile performance boost? It can take us 20-30 seconds to render a more complex map. Which is a long time to wait on a web page...

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.

My question is simple (the answer may not be...), What I am looking for is a way to save a file as an encrypted file (so know one can open it except in visual basic or a way to save it with a unique ending that only visual basic will recognize. I will also need to know of a way to open or load the file to.
This is going to be used in a game I am working on (and yes...I know visual basic isn't really meant for games, but it is coming together pretty well). I was originally going to have it save as a text file, but then everyone could open, read it and even change there stats. That is what this file will contain, the stats for their character, and when they load it, it will place the values into the correct spot.
I am a partial beginner or intermediate coder, I can understand code, I just don't know all there is, like saving and loading, and this is probably a little harder.
