Re: How can I draw a hexagon with children in VB.NET code?

21-Jul-12 21:46

Is it possible to draw a hexagon with children and paint it with Lineargradientbrush? If it is possible, can somebody help me with the sample?
Example is the type used in Microsoft office 2007 color dialog box.

Trying a Google search first would have got you these links[^].

One of these days I'm going to think of a really clever signature.

Ok I am waiting. I believe that there must be a clever way of doing that.

I googled it as you directed and I got good one but it is written in C++ and I am not familiar with C++. This is the link (www.codeproject.com/Articles/24970/XColorDialog-MFC-color-picker-control-that-disp). Can you help in converting it to VB.NET or C#? Or can you build the DLL in the same language?

Tht grey mass between your ears is not there to keep them apart. How about using it to figure it out yourself? I know it's unfair, but that's the usual way you accomplish something on this planet.

At least artificial intelligence already is superior to natural stupidity

I am aware of that but remember that 2 good heads are better than one. Well, you advice is very ok. You learn better when you do thing yourself but other persons' idea can pave you way. Your contributions on how to do it is also impotant.

I don't know what you Googled but if you had bothered to follow the link I provided you would have found lots of samples for drawing shapes in VB.NET.

Hi, I'm trying to render the contents of a window, with desktop composition disabled, on an off-screen buffer. I have no control over the window and the only thing I have is the window handle and the DC. I thought about allocating an off-screen DC and doing something like:

/* The window handle is stored in the
   hWnd variable and the offscreen DC,
   is in hDC */
PostMessage(hWnd, WM_ERASEBKGND,
            (WPARAM)hMemDC, 0);
PostMessage(hWnd, WM_PAINT, 0, 0);

But it doesn't seem to work. Please note that I don't want the application to render on the primary display DC. In other words I want to redirect it's graphical output, and blit the result in my window.

GDI OpenGL composition

Hi,

I'm trying to mix Device Contexts and OpenGL but not the usual way. I don't want to draw with GDI on top of an OpenGL scene. What I wanna do, is apply an HDC bitmap as a texture on an OpenGL polygon. I know that this is generally a bad idea, but if you know anything about how is that possible, you would be very helpful. I'm coding on C/C++ on Win32. A DirectX 8/9 solution would also be appreciated.

Found the solution

Finally found the solution myself. If anyone else is interested in that, the process is simple. You create a bitmap from the DC (there are many websites that describe this), and then you apply that BITMAP object as a texture, the way you'd apply any other bitmap texture.

No information or explanation, just a code dump. How do you expect anyone to help you without explaining exactly where the problem occurs, and what that problem is.

Binding 100,000 items to a list box can be just silly regardless of what pattern you are following. Jeremy Likness

If you really want help, you will reduce this to the relevant snippet of code where your problem is and then ask a clear coherent question and description of your problem. No one is going to go through this mess to try and figure out what it is that you want to do.

Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.
Sometimes it takes a lot of work to be lazy
