Direct X error

sciwizeh — Fri, 11 Dec 2009 21:27:57 GMT

Hello I have a sample program from a book, it's not working properly, when the function

d3d10createdeviceandswapchain

is called the error checking causes the program to fail, after adding a few lines of code I found that the error code isn't one of the constants that the function is supposed to return, the code is -2147467263

I couldn't find anything on the code, does anyone have a suggestion?

Edit: when I pass the method the D3D10_DRIVER_TYPE_REFERENCE it doesn't throw that error, but the entire program as well as Visual Studio stop responding and both require task manager shut down

Running BlueJ source in Eclipst doesn't work properly.

Hello all,
I have the bluej source code in eclipse, and it compiles fine, but when I try to run it BlueJ starts fine, and then pops up an error window that says that bluej couldn't create a VM.

My installed BlueJ has never given me this error before, so it isn't the computer. But, when I try to run the source through the command line BlueJ freezes at the splash screen, I think I'm missing something about that.

here's a picture of the error message http://matrixpeckham.googlepages.com...pseproblem.jpg

could this be eclipse preventing the VM from being created? How can I fix it?

Edit: I forgot to mention that I tried turning off my firewall, and it didn't do anything to help.

Making an extendable program?

Hello all,
As you may know by now, from my previous posts recently, I am working on a Paint application. My question, then, surprisingly does not involve Graphics or Swing.

So my question is this: I would like to be able to have a directory such as "APP_HOME\tools" or something similar, and I would like to have in it some .class files, that the program doesn't necessarily know anything about, perhaps except a known implemented interface, that will be loaded on start of application.

Can anyone give me a suggestion? Perhaps an overview of how a program like NetBeans or BlueJ handles plugins? Any information would be welcome.

Graphics.drawImage() non-transparent image transparently

Hello all,
I have a new problem with my Paint app, I have a TYPE_INT_RGB buffered image, and I'm drawing a "preview" of it, but I want to be able to see through the "preview." Is there a way to make it appear transparent without modifying the actual image?

JList doesn't pass events to sub component

sciwizeh — Tue, 17 Nov 2009 15:59:25 GMT

Hello All, it's been a while since I've had a question for you all.
I'm trying to write a paint app, I've done so before, but this time I decided to add Layers, and I wanted a JList of the layers, I wrote a cell renderer, that not only renders the names of the layer, but a small scale image of the layer, but I also have two checkboxes on the component that gets returned, and the checkboxes don't change when clicked, is there a simple way to make the list pass events down to other components?
