It's ok! And thanks, it helped!

It could help but I never worked with WMI, so I will need a example of its use. I've just downloaded the WDK and I will try to read the temperature by making a driver. This could be fun! :D

I'm trying to use __readmsr() intrinsic function to get the temperature, but it keeps giving this error: "Unhandled exception at 0x000000013fd81009 in test.exe: 0xC0000096: Privileged instruction." It seems that rdmsr instruction must be executed in privileged mode. EDIT: Is there any way of switching from user-mode to kernel-mode instead of making a driver?

I'm trying to make a program that reads the temperature from the cpu and then sends it to my arduino duemilanove, where I have a 4 digit 7-segment display. I've been searching for a while but found nothing about reading the temperature from cpu's DTS (Digital Thermal Sensors). I don't want to use CoreTemp or any other related tool. EDIT: By the way, I have a asus n61jq laptop with intel core i7 720QM

I'm using a Sony Ericsson w910i (not a smartphone). The purpose is to create a java applet for my phone, that enables it to comunicate with my laptop, through bluetooth. I searched online about this type of connection, but found nothing.

By the way, which formats do you use?

That is exactly what I wanted to know. Thanks.

And if we have

struct point
{
float x;
float y;
float z;
};

struct face
{
point a;
point b;
point c;
};

face f = {0}; // <- This will initialize to zero the struct, and its elements?

Hi I'm trying to convert a python script from blender to C++. The script is used to import 3D data from a file. Things have been going right until I got to this part of the script:

# Generate verts and faces lists, without duplicates
verts = []
coords = {}
index = 0

for f in faces:
if f: # Line might be blank
for i, v in enumerate(f):
try:
f[i]= coords[v]
except:
f[i]= coords[v] = index
index += 1
verts.append(v)

Since I don't know python, I need help to interpretate this part of the code.

struct foo
{
int i;
};

foo f = {0}; // <- What does this mean?

The RAW Triangle Format is parsed by reading lines, not individual values. That was what I didn't know.

I think that I've found the solution for my problem here.

Blender is outputting a strange kind of list of triangles. For instance, a circle, it seems that Blender is outputting a triangle fan.

By the way I'm using Blender 2.49a for exporting the geometry files Here

HRESULT load_RAW(const char *fname, IDirect3DVertexBuffer9 **buffer, int *count)
{
HRESULT hr = E_FAIL;
FILE *f = fopen(fname, "r");
if(f)
{
(*count) = 0;
float tmp[3] = {0};
while(fscanf(f, "%g %g %g", &tmp[0], &tmp[1], &tmp[2]) == 3)(*count)++;

	rewind(f);
	HUD\_VERTEX vert\[(\*count)\];
	memset(vert, 0, sizeof(vert));
	for(int i = 0; i < (\*count); i++)
	{
		fscanf(f, "%g %g %g", &(vert\[i\].x), &(vert\[i\].y), &(vert\[i\].z));
		if(ferror(f))
		{
			fclose(f);
			return hr;
		}
	}
	fclose(f);

	int byteLen = sizeof(vert);
	hr = g\_device->CreateVertexBuffer(byteLen, D3DUSAGE\_WRITEONLY, HUD\_VERTEX\_fvf, D3DPOOL\_MANAGED, buffer, NULL);
	if(FAILED(hr))return hr;

	void \*ptr = NULL;
	hr = (\*buffer)->Lock(0, 0, &ptr, 0);
	if(FAILED(hr))return hr;

	memcpy(ptr, vert, byteLen);
	hr = (\*buffer)->Unlock();
	if(FAILED(hr))return hr;
}
fclose(f);
return hr;

}

And here

HRESULT Device_Render(IDirect3DVertexBuffer9 *buffer, int count)
{
HRESULT hr = D3D_OK;
hr = g_device->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_COLORVALUE(1.0, 1.0, 1.0, 1.0), 0.0, 0);
if(FAILED(hr))return hr;

hr = g\_device->BeginScene();
if(FAILED(hr))return hr;

g\_device->SetFVF(HUD\_VERTEX\_fvf);

g\_device->SetStreamSource(0, buffer, 0, sizeof(HUD\_VERTEX));
g\_device->DrawPrimitive(D3DPT\_TRIANGLESTRIP, 0, count);

g\_device->EndScene();
g\_device->Present(NULL, NULL, NULL, NULL);

}

Yes. I used that tutorial from "drunkenhyena.com" to understand more about the direct 3d The code I'm working is huge. Here is the whole code. main.cpp

Are you asking how to find executable code inside a program and copy it to another file, in order to run it? If so, you have to learn the structure of the program.

Hi I'm creating a 3D app which the main purpose for it is to be a game engine renderer. The file format that I will use for geometry is the RAW Triangle, since it is very simple to understand. I've created a function able to read the entire 3d file and parse it to a IDirect3DVertexBuffer9. Things are going fine here, but the problem is when it becomes rendered. I'm not getting the full object rendered, it seems that file is corrupted.

Hi I've been facing problems with this new type of connection, and I want some examples on how to establish a serial connection between my phone (SE w910i) and my laptop, through bluetooth. I'm not an expertise on this topic, even on this programming language. It was better if I could make java applets in C#

Hello everyone! I'm new on mobile development, so be gentle with me. I need some information about how to create a serial communication, like the way arduino is connected to computer, a serial protocol. I want to create an applet to communicate with a C# application, for data exchange.

Here is the point: Getting a number from the slider control and make it integer (a.k.a. removing fractional part) so that I can send it through the serial port When speaking about integers, it doesn't mean to be a 'int' variable, but in other words, a natural number
