How to do a interactive camera 3D view in C# - C# Discussion Boards

Thats right. But theres only one problem. If the user has scroll down the Grid and i clear the DataTable and refill-it then scroll will go to the first item in the list. Is there a way of avoinding that?
Thanks for your reply.

My file contains records which look like this:

EMPLOYEE001,M,20081105

First column is employee ID, second is gender and third is date.

I want to read this from a comma separated variable text file and think a regular expression is the way to do it. I do not want to create a dataset from the file.

Help much appreciated Smile | :)

To do what? You haven't asked a question, and a regular expression will not read records from a file.

Sorry for not being more clear. I will use a regular expression to validate my record I read from the .csv file.

Like this:

Regex regex = new Regex(expression);
string[] parts = regex.Split(record);

Sorry again Sniff | :^)

And you are basing that on? If you don't know how to use regular expressions, why do you think that's the way to do it?

Please see my answer above Smile | :)

Sorry, but I thought I wouldn't need to explain that I could get the record from the .csv text file.

This:

<br />
",(?=([^\"]*\"[^\"]*\")*(?![^\"]*\"))"

I have done a code on 3D office. I would like to do it in interactive way which by pressing the arrow button, the object can be viewed from different perspective. However, my result come out with static image and my objects all disappear. The object exists if i doesn't include the Checkmovement function inside. I wonder what mistake i have done. Could anyone please kindly help me review my code and give comment. Thanks.

Why would anyone want to wade through over 400 lines of unformatted code to work out what you have done wrong? Try running in debug mode and see where things go wrong.

Bob

Agreed.

Reading the unformatted code is not easy, especially since you don't limit it down to what's important.

I would assume you've just got some bad math going on in the camera position calculations.

I would look at your values you're calculating for the following line of code and verify you're not moving the camera into a position/angle that is away from your 'office'.

Scene.SetCamera(sngPositionX, sngPositionY, sngPositionZ, sngLookAtX, sngLookAtY, sngLookAtZ);

Your initial values are:

sngPositionX = 0;
sngPositionY = 20;
sngPositionZ = 0;
sngLookAtX = 0;
sngLookAtY = 20;
sngLookAtZ = 50;

So, see if you're pointing your camera in the wrong direction.

Thanks to Andrew for kindly answer my question. Sorry to Ashfield if i have ask a stupid question but i have debugged it and it appeared no error. So, i just want to get what is wrong behind my logic. Anyway, thank you!

There are no stupid questions.

Regardless, by spending a little more time up front phrasing your question and making it easy to get a grasp of your problem, you'll find people are more willing to spend the time to answer you. It's just some helpful advice.

Hello everyone,

I have face problem is "Unable to load DLL 'some.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) ", when trying to load the dll file into a windows application. I developed a windows application in VS2005 and want to import a dll file from another program into my project and use it.for that i have just add that dll to the solution explorer. But when I try to call one of the function in the dll file, I got the error message "Unable to load dll 'some.dll". I put the "some.dll" file in the debug folder.Can anyone help me out with this? thanks and really appreciated!

I know that not all .dll can be loaded by VC#;

What debug folder? Try putting it in the same folder as
the .exe file using the dll is in.

how to change it?

I haven't got Visual Studio infront of me to confirm this, however this article:

http://www.java2s.com/Code/Java/SWT-JFace-Eclipse/DemonstratestheColorDialogclass.htm[^]

states that you can impliment it this way:

ColorDialog myDlg = new ColorDialog();
myDlg.setText = "my title text goes here...";

I don't think you can. The color dialog is actually the native ChooseColor which doesn't have anything to change it.

Normally I'd suggest using FindWindow and SetWindowText, but seeing as it's a dialog that's not an option.

It'd be easier to make your own, maybe a PropertyGrid with just one property of type Color.
