I know this has probably been done a million times. But I like to share, okay? I'm learning vc++ and winforms programming. So, hopefully someone would find the code and tool useful. I found most of my answers by searching the irrlicht forum. You can find some excellent info on this forum.
Anyway, here's what it can currently do (usual stuff):
+ fullscreen option on/off
+ stencil buffer option on/off
+ vsync option on/off
+ display driver
+ screen resolution height
+ screen resolution weight
+ screen resolution bits
+ read in values from xml file
+ minimal error checking
I'm currently working on getting it to write to xml. Also, I'm going to add in more error checking code after I've completed the code to allow it to write to xml. I'm also planning a x64 and a .NET 3.0 version (vista only). But let's not get ahead of ourself, eh?
Here're some screen captures of the program (i'm running vista that's why the window looks so funky; also ignore the background -- man, that would be nice to have a grass node looking like that, eh? *lug nudges bitplane*
):
Here's the xml file that the program uses:
Code: Select all
<!-- Pre Setting Configuration File -->
<Config>
<!-- Misc Options -->
<Fullscreen value = "False" />
<Stencilbuffer value = "False" />
<Vsync value = "False" />
<!-- Display Options -->
<DisplayDriver type = "Null Device" />
<ScreenResHeight value = "640" />
<ScreenResWidth value = "480" />
<ScreenResBits value = "8" />
</Config>
I used the "/clr" switch instead of the "/clr:safe" or "/clr:pure" switch in order to take advantage of the non-.NET version of irrlicht. I can't seem to find the operation to get the mode list in the .NET version of irrlicht.
This is pretty much the main guts of the code since everything right now is done when the form first loads:
Code: Select all
private: System::Void Form1_Load(System::Object^ sender, System::EventArgs^ e)

// instantiate a dummy irrlicht device
IrrlichtDevice * device = createDevice(
video::EDT_NULL,
core::dimension2d<s32>(0,0),
false,
false);
// query the device to obtain the available video mode
IVideoModeList * availableVideoModeList = device->getVideoModeList();
// define array to hold a formatted listing of the availabe modes
wchar_t formated_listing[64] = L" ";
// go through all available video mode for graphic adapter
for(int i = 0; i < availableVideoModeList->getVideoModeCount(); ++i)
{
// format available modes into desired listing
swprintf(
formated_listing,
64,
L"%i x %i pixels @ %i-bit colors",
availableVideoModeList->getVideoModeResolution(i).Width,
availableVideoModeList->getVideoModeResolution(i).Height,
availableVideoModeList->getVideoModeDepth(i));
// convert wchar_t to string object
System::String^ mode_listing = gcnew System::String(formated_listing);
// add formatted mode to combo list box
cmbScreenResolution->Items->Add(mode_listing);
}
// load in values from xml file if one already exists
io::IXMLReader * xml_file = device->getFileSystem()->createXMLReader("pre_settings.xml");

Download from here (uses rar; 557 KB):

The buttons aren't working yet (close app using the "x" in the upper right of the program window), so you can try changing the xml file and see it load the values. It requires the .net 2.0 runtime. You can download it from here:

Bye for now.
