Anyone know if it's possible to import images into a project file for Visual C++ Express 2008? I think it should be, but the help menu only described the process for Visual Studio, and I can't find the answer on the internet. It's not that big of a deal, but it seems there should be a way so you don't have to do it manually.

By import i assume you mean make it as part of the exe itself and the answer is yes if you make it part of the resource for the exe. Look up something called ResEdit. and when you call the loadimage function it should have a filed where you can difine it as a resource and instead of useing its name you use a marco called MAKEINTORESOURCE and that will acomplish what you want.

Check up on the LoadBitmap function on msdn to figure out what fileds will need what info and get a copy of ResEdit as it is a free resource editor.

VC++ Express does not come with a built in reource editor but can still compile adn use the files so you should not have much of a problem after that.

One thing to note is it is not a good overal idea to make large images part of the exe small ones like icons and things of that sort are ok.

Inmages in the exe are stored in a bitmap form and thus take up quite abit of space so avoid makeing larger then needed Exe's.

Thanks muchly.

On a completely unrelated topic, does anyone have any tips on rotating a directional light? It's a recommended exercise for a tutorial I'm taking, but I can't think of where to start from.

Well that all depends on what your useing is it a 3d eviroment is it Opengl or DiectX you need to clarify these things so pepole can answer you better :)

if its OpenGL google NeHe and it will give a list of a nicely sized cache of OpenGL tutorials if it is not then try to googl NeXe it is for direct 3d stuff

Regards Jouei.

Remmber to rate pepole on how they help you its there for that reason.

// this is the function that sets up the lights and materials

ZeroMemory(&light, sizeof(light)); // clear out the struct for use
light.Type = D3DLIGHT_DIRECTIONAL; // make the light type 'directional light'
light.Diffuse.r = 0.5f; // .5 red
light.Diffuse.g = 0.5f; // .5 green
light.Diffuse.b = 0.5f; // .5 blue
light.Diffuse.a = 1.0f; // full alpha (we'll get to that soon)

D3DVECTOR vecDirection = {-1.0f, -0.3f, -1.0f}; // the direction of the light
light.Direction = vecDirection; // set the direction

d3ddev->SetLight(0, &light); // send the light struct properties to light #0
d3ddev->LightEnable(0, TRUE); // turn on light #0

ZeroMemory(&material, sizeof(D3DMATERIAL9)); // clear out the struct for use
material.Diffuse.r = material.Ambient.r = 1.0f; // set the material to full red
material.Diffuse.g = material.Ambient.g = 1.0f; // set the material to full green
material.Diffuse.b = material.Ambient.b = 1.0f; // set the material to full blue
material.Diffuse.a = material.Ambient.a = 1.0f; // set the material to full alpha

d3ddev->SetMaterial(&material); // set the globably-used material to &material


I'm thinking I'll have to make a constantly increasing variable to represent radians around a circle, and then use sin/cos to make x and y values that I'll plug into the light's Direction. Sounds like the most efficient way to do it.

Okay, so when I tried to implement my little plan, I realized that the light struct had gone out of scope, so I don't really have any way to "update" it.

Is there any function I can call to change the properties of the light during runtime?

Well i am not sure as i do not deal with direct3d myself. One thing you could do is check msdn.com its a microsft devlopment network archive of sorts.

or the other option is save the structure globaly so its allways there not by far the best solution but should work if it is a must.

Sorry i could not be of more help. I suggest geting this post moved to the DirectX forum if an admin is checking it it will probaly get a few more responses.

Or close this one Post and label it as sovled and start a nwe one in the directX forum. The latter of the two is better.

Regards Jouei.
