I did not really want to create as what i am showing in the second picture. What i actually wanted is to draw a curved (maybe a porsche, ferarri , or a lamboghini). Can i know how to draw curves along the edges ?
View 7 Repliesi have two bezier curves placed at a distance apart in space.curve 1 has control points A0, A1,A2, A3. A0 and A3 lie on curve and are its end points Curve 2 has control points C0,C1, C2, C3 . C0 and C3 lie on curve.and are its end points
i want to join the two curves A and C with an intermediate bezier curve B. the intermediate Curve B has control points A3 and C0 which lie on the curve and are its end points. the intermediate control points B1 and B2 are unknown to me. also the joining should be smooth enough. please help as to how to proceed. have read alot about beziers but dont know how to do this.
I have a cubic bezier curve where the first and last points are given (namely P0(0,0) and P3(1,1)).The other two points are defined like this: cubic-bezier(0.25, 0.1, 0.25, 1.0) (X1, Y1, X2, Y2, also those values must not be smaller or larger than 0 or 1, respectively)Now what would I have to do to get the Y coordinate for a given X, assuming there's only one? (I know that under certain circumstances there can be multiple values, but let's just put them aside. I'm not doing rocket science over here, I just want to be able to get Y multiple times per second to do transitions)I managed to dig up this: y coordinate for a given x cubic bezier, but I don't understand what xTarget stands for., also this is no homework whatsoever, I'm just a bit pissed at the fact that there's no comprehensible stuff about cubic bezier curves on the internet.

View 7 RepliesI'm working on a program that will generate and graph random parabolas with integer vertices. I've got a 360n x360 pictureBox set up and used a for-next loop to draw in a grid consisting of 15 x 15 squares. when I plot the generated parabola I get some unwanted lines/curves. I think this is due to the fact that the (0, 0) point of the picturebox is in the upper left corner and the (0, 0) of my grid is in the center of the picturebox. Is there a way to "move" or "set" the pen position to the first point I wish to plot for my parabola without leaving a mark or trail? Or is there something else I can do? I've tried drawing an invisible line before my g.DrawCurve(plotPen point) but when the DrawCurve is executed I still get an extra line.

I have followed a tutorial from Zedgraph's wiki but I still seem to be having issues. When I run the code below, only the 3 curves on the Y Axis plot. I know the datasource is correct from which the 4 curves on the second Y axis are being created, because I have checked the table after creation. For some reason, however, the curves do not show up and the Y2 Axis does not change its scale to reflect any new curves. Does anyone see what I'm missing here?

is it possible to make the edges on a form rounded rather than a sharp edge?
View 2 RepliesI'm trying to make a program that runs programs using image analysis. It will Recognize images on screen so that they can be clicked. Well when i was working on it i had an ideal. I could get the edges of the screen/window i'm using. Make a calculation to grid off areas of parts of the screen. Making the program not have to process the entire screen every time. So that it only has to call to process a grided off zone.
How every i dont know how to get the edges of the screen/window. Could some one link info on how to do it or give some code snippits. Thx for an info that you give.
I'm trying to do for a website. I've got a header banner that is 900px wide, and I want to display 4 random images across the banner. (I've got about 20 photos at this point, and I want the header to select from them.) I can get the code for the random selection, but what I'm looking for is a way to blend about 10 pixels near the overlap. If I have each picture exactly 225px wide, I get a "hard" line between the images. I'd like to make the images a little bit wider and soften the edge by overlapping and blending the images together. I have figured out how to get the image back to the web browser, but I don't even know where to start on trying to figure out the blending. Graphics really aren't my thing.
View 2 Replieshow I could make a custom form, by setting the FormBorderStyle to None, and making it transpatent without setting the TransparencyKey to a color...
Because when you set the TransparencyKey property to, let's say 121; 121; 121, and it got a button which got the same color on the ForeColor, and then it disapears...
Here's an example of how it looks like when the form is transparent:

I tried to skin my application and failed. I can get it to work if I don�t have semi transparent pixels on the outside of my form. But I want to use a skin I found on Deviant art that was made for Miranda. It is really nice but and it has a shadow around it. To get it to work in vb.net (I�m using 2005 btw) I have to fill around the main picture and take out the initializing (I think that is what it is called). But then the form�s edges are choppy. How does Miranda allow the shadows but I can�t in vb.net?
I first tried to do it the easy way. I set up some transparent panels with transparent pictureboxes in them and put my corners and middle fills as the backgrounds. I made the form with no border and set the transparent key to transparent. That didn�t work, so I made the form magenta and the transparent key magenta. The outside of the for where the shadow is was drawn on the magenta and the magenta bled through. So I edited the png�s to be magenta all around the form (eliminating the shadows) and it worked, but the corners were choppy.
Then tried some code I found on the net that tried to make a new control as a transparent panel. It was overriding the paint events and drawing to an off screen bitmap. I really didn't understand it and it just showed up as a blank screen. There has to be a way to do this.
My report is an image in a picturebox. I want it so if the user clicks on it it will zoom larger --- while the picturebox remains the same size. That's important. The examples I've found for picturebox zooming cause the picturebox to get bigger and smaller. I need it to be like an Access report. Click on the report and it gets bigger. Click again and it goes back to the full image. Of cours when you're zoomed in, the perimeter of the report is not visible. So I'd like to be able to drag the image as well so the unseen portions can be seen.

View 1 RepliesI have been working on a windows form over the last couple days and I have hit a brick wall when trying to move my controls.
I think I have basic understanding of anchoring and docking but I'm not getting the results I'm hoping for so I have attached some screen shots of what I'm trying to do.
It's not about re-sizing more about moving the controls to the outer edges when my form is maximized.

I have multiple forms within a form, typically up to 16, and I want these "inside" forms to snap all edges between eachother or the parent form edges, when a form is resized or moved, and edge comes within x pixels of any other edge.How should I approach this? What I can think of is to raise an event on the form that is moved/resized which calls a parent form handler method that loops through all the forms, check the edges and then keeps fixing (repositioning) the active form if any of its edges is close to any other form edge

View 6 RepliesI have a VB app which draws primitive shapes (lines, filled rectangles etc.) into a picturebox control (from its paint event). I've since found out that a picturebox is probably the worst control to use for this. I've also found out that it's better to draw directly onto the form but I don't really want to do this as a control gives clipping for 'free'.
What would be the best control for this? The panel control looks like a good candidate but the experiment I tried actually performed worse
