Hello,

May be this project[^] will help you. This is the OpenGL wrapper for C#.

This OpenGL framework for .NET is very good: http://www.taoframework.com/[^]

To get started put a TaoPanel(I think that's the name of the control) on your form and inside it's OnPaint event handler do all your OpenGL stuff.

You keep posting this, and you keep saying 'I want a drawing program', not 'I want to write a drawing program'. Which is it, do you want help writing one ( ask more specific questions ), or do you just want one ( this is a board for asking questions with your code, not looking for complete code )

OpenGL is a 3D framework. It's not really useful for a program like this one, in fact, apart from a bizarre way of achieving layers, I don't see how OpenGL would help you much at all.

You're not going to find it here. This is the right place to ask if you're writing a program and have specific questions to help you do it. If you need to find a program, you probably have to pay someone to write it for you, if you can't find it with google.

What do you think OpenGL is ? It's a 3D engine, anda fairly tired one compared to DirectX ( in my opinion ). It has NOTHING to offer the author of a 2D drawing program. It does not manipulate raster images, it manipulates objects in 3D space. It's not an appropriate tool for a drawing program, unless you mean a program that creates 3D shapes.

No, you apparently hope someone will write a program for you. You need to pay someone to do that, especially something of the size you're asking for. Or you can look around in sourceforge or something for a free project that does what you want. Assuming you've tried google, one can assume what you want does not exist, and this site is not a place to look for people to write programs for you, for free.

I hv dropdownlist on a c# page connected to a database(MS Access).
I want to get values onto my datagrid when I select a value from the dropdownlist.The Item I select from the dropdown will determine what I get loaded onto the datagrid.

Please help with some code.Mine is*********

connect.ConnectionString = strng;

OleDbCommand command = new OleDbCommand("Select * from Extensions Where FilterByKey = '" + DropDownList1.SelectedItem + "'", connect);
connect.Open();
command.Connection = connect;
datareader = command.ExecuteReader();
if (datareader.Read())
{
// This will filter database data by the FilterByKey and then populate the datagrid
GridView1.Items.Add(datareader2[0].ToString());****not working
LabelMessage.Text = "All values displayed";
connect.Close();
datareader.Close();

What version you are using?

If it is 2005 then in the gridview's accessdatasource you can specify the table and in the "where" option you can bind the filter field with the control and select the dropdownlist,

Otherwise if you want to do it in coding write the below coding in the dropdownlist_selectedindexchanged event and don't forget to enable the option "enable Auto post back"

OleDbDataAdapter oda = new OleDbDataAdapter("Select * from Extensions Where FilterByKey = '" + DropDownList1.SelectedItem.ToString() + "'", connect);
connect.Open();
Dataset ds =new Dataset();
oda.fill(ds,"MyTable1");
GridView1.DataSource=ds.Tables[0];
Gridview1.DataBind();

And it says 'Are you using or missing a using directive

DataSet is found in System.Data namespace so you import that namespace.

Thanks for ur reply.
If you can provide me the exact syntax, then it'll be much helpful for me...

Is it necessary that file should be shared in this case ???
If yes, then programmatically how to make that file shared ???

Thanks

Devesh Mishra

Christian Graus3-Jun-07 22:43

3-Jun-07 22:43

Wow. You want to know if a file needs to be shared before you can read it, and you want to know how to write code to force a file on another machine to be shared ?

Is someone paying you to write this code ?
