SharpGL: how to add a solid object to a scene - C# Discussion Boards

Hello Jassim,

It is because Indexing start from 0 not from 1.

Look,
Your gridContacts.RowCount will return 10, if you have 10 rows and your for loop will be executed 11 times. In grid, there are only 10 records, so last record will be blank line.

So,

start index from i = 1 or use i < gridContacts.RowCount

But by looking at your code, you should use i < gridContacts.RowCount. Otherwise you have to change some of your code too.

Thanks... Have Fun Poke tongue | ;-P

There are two ways of using this. To make the correction on your code, it should be,

C#

for (int i = 0; i < gridContacts.RowCount; i++)
{
}
// You dont need the <= as the index starts from 0

Alternative way is to try with For each, which i prefer the best suit for Datagrid,

C#

foreach (DataGridRow drv in gridContacts.Items) // or try(gridContacts.Rows) either /or one
{
}

Correction in For Loop-

for (int i = 0; i < gridContacts.RowCount; i++)

beside the error you get you're making the mistake of mixing DAL code with GUI code, which is generally not done, and most certainly not in production code.

I can recommend you two articles Smile | :)

A smidgen on research [^] will get you plenty of information. This search changing some of your words may be useful.

Ahh you want the BEST way, that will depend on your requirements, most just put in a short expiry date.

Please don't cross-post.

You'll never get very far if all you do is follow instructions.

I am using SharpGL to add a solid object to a scene by clicking a button.

C#

private void InitElements(Scene scene)
{
    var objectRoot = new SharpGL.SceneGraph.Primitives.Folder() { Name = "Root" };
    scene.SceneContainer.AddChild(objectRoot);
    // This implements free rotation(with translation and rotation).
    var camera = GetCamera();
    float cmX = camera.Position.X; float cmY = camera.Position.Y; float cmZ = camera.Position.Z;
    float tgX = camera.Target.X; float tgY = camera.Target.Y; float tgZ = camera.Target.Z;
    float upX = camera.UpVector.X; float upY = camera.UpVector.Y; float upZ = camera.UpVector.Z;
    objectArcBallEffect = new ArcBallEffect(cmX, cmY, cmZ, tgX, tgY, tgZ, upX, upY, upZ);
    objectRoot.AddEffect(objectArcBallEffect);
    var axisRoot = new SharpGL.SceneGraph.Primitives.Folder() { Name = "axis root" };
    scene.SceneContainer.AddChild(axisRoot);
    axisArcBallEffect = new ArcBallEffect(cmX, cmY, cmZ, tgX, tgY, tgZ, upX, upY, upZ);
    axisRoot.AddEffect(axisArcBallEffect);
    InitLight(objectRoot);
    InitAxis(objectRoot);
    InitAxis(axisRoot);
    InitFrameElement(6, 24, 7, objectRoot);
}

After I initiate the solid elements in scene, I would like to add a solid object to that scene by clicking a button. I successfully add it in scene. But I cannot drag and rotate it with the initial elements in the scene. It means I didn't successfully add it to the same scene. Thanks in advance.

C#

private void btnAddEllement_Click(object sender, EventArgs e)
        {
            var objectRoot = new SharpGL.SceneGraph.Primitives.Folder() { Name = "Root" };
            var scene = this.sceneControl1.Scene;
            addCylinder(objectRoot, 50, 30, 100, 5);
            scene.SceneContainer.AddChild(objectRoot);
        }

There's far too many silly questions appearing on this forum, like 'Please write my project for me'. This place used to be the best forum around, and the first place I would turn to, but trying to wade through all these inane questions is just too much.
Has anyone got any ideas as to where I can go with a more erudite audience?

Mars.

The quality of questions has plummeted on every site out there. We don't have a monopoly on idiots here.

Try dipping your nose into Q&A for a taste of low quality questions. You might want to take your comment to the bugs @ sugs forum.

Also such a comment coming from someone who has almost no involvement with the site, 28 post in 3 years, is a little ironic.

Some people have work to do, and can't afford much time to hang about reading silly questions. What time I do have I prefer to use wisely.

With an attitude like that, you won't be missed.

Just give up. There's no place that consistently has questions worth anyone's time. The only way to find such questions is, unfortunately, to read through piles of excrement.

And this one doesn't really help. The Lounge is the place for this sort of discussion.

That's like walking into a bar and asking where one could go for a good drink Smile | :)

The outcome is predictable.

which security better for my project

The one that makes it secure. Please read http://www.codeproject.com/Messages/1278604/How-to-get-an-answer-to-your-question.aspx[^].

We really can't answer that: we have no idea of what your project is, what environment it will run in, or what kinds of data you are handling. "Security" in this context could mean anything from strong encryption, to hashing, to "doing proper backups".

Since the term "security" will vary depending on all of those, we just don't have anywhere near enough information to begin answering.
