Hi,
Have a look at the Process class and its Start() method.
Specifying a file acts just like double clicking the file in Windows Explorer.
For more control, use the StartInfo property.

I am using C#, OpenGL and want to draw the Text on screen ... I went to OpenGL site and see the GLFont and other methods. Problem I face in these are:
They give Code in C++ that uses pointers and references that are not supported in C# and it call them as unmanaged code, i write unsafe modifier in front of it but other problem arises. So, these codes are not helpful unless they are in C# language.
if anyone know the method how to draw text in openGL or how to use C++ code in C# language then tell me .... I will be very pleased for your help ....

Hey,
be careful not to mix up things here.
First, OpenGL is a native C Library, so 'talking to' OpenGL, at some point, requires you to communicate with it - good news is, you don't have to that yourself (but you can if you want to).
Check out the following libraries which may help:
o Tao Framework[^]
o EaseWrapperSDK[^]
NOTE: Tao is for C#, EaseWrapper is for C++. If you haven't worked with managed C++ / Interop, look at Tao first. Tao has more to offer than just wrapping OpenGL, by the way (also wraps SDL, OpenAL, etc.)
Second comes text rendering. There are a number of ways to it:
o Manually. This involves a texture which contains letters and numbers. Then, you render little rectangles with orthographic projection on the screen. For a GUI, you want to do this after the scene is rendered. This is not as hard as it may sound.
o Using a library such as glFont. As far as I know, glFont is a program or a library. Its not an OpenGL-Command. However, I don't know any C# gl font-render libraries, so again you might have to mess with a managed C++ wrapper.
o Using a high-level library such as CeGUI which has a lot more to offer than text rendering. It is included in the EaseWrapperSDK, but it's also C++.
There might be a GUI library in Tao, I'm not sure.
I suggest you go for Tao and have a look at thoseNeHe Lessons[^] which concern font rendering. He presents a number of options. NeHe's tutorials are available as C#, but you will have to (in other words, you should) convert them to Tao if you use it.
Hope that helps,
Chris

Thanks 4 the Reply ... NeHe Lessons's Link was not Opened in my browser i think link is broken ....
I want to ask one more thing that i am using this code ... where height is the Font height and startPoint_x and startPoint_y is the point where text is to be display
CsGL.OpenGL.GDITextureFont myGDITextureFont;
Font newFont;
newFont = new System.Drawing.Font("Microsoft Sans Serif", (float)height);
myGDITextureFont = new GDITextureFont(newFont, 'a', 'z');
GL.glTranslatef((float)startPoint_x, (float)startPoint_y, 0);
myGDITextureFont.DrawString(text);
and in this way text displayed but when i click on it it turns into solid bar .... Can you tell me, What is the problem with this code ....

Hi,
the link to NeHe works out for me. If it doesn't work, you might want to google it or visit gamedev.net, which links to NeHe.
As for the code you supplied, I don't see any trouble.
However, the problem might be caused by your update/resize methods. The question is: Under which circumstances do you redraw the screen? You have to do that whenever Windows tells you to do so, because it might have invalidated the screen. This can happen when resizing, minimizing, when another application draws in front of yours or even if a different control receives focus. The latter happens upon click, so make sure you redraw the scene for the events named above.

I have been looking at the NeHe lesson and they seem to be in C++, sorry if im being blind.
Also what is the best way to rotate text, i.e. having it writing at the angle or vertical.
Thanks

Hey guys,
I'm developing a jukebox kind of app with video support. Currently I support up to three 'rooms' which can play audio individually. The audio is handled by DirectX (9c) and then ported to sound device which handles the rest for you. Now in order to support multiple 'rooms' I need to insert more sound devices in the machine.
I want to use only one 5.1 sound device, and send the audio of multiple rooms, to different output ports on the sound device. Can anyone give me a hint?

i have a datatable , i mean a temporary table , which has nothing to do with the sql server 2000 database.
now my question is , how can i filter the records from that temporary table , to filter the records.

use Select() and write you filter, that will return DataRow[]
Code:
DataRow[] Dr = DT.Select("EmpId = 'E999'");
all rows, whose EmpId is equals to E999 will store in Dr
hope this will help

is there any need of type casting ?

Select returns an array of DataRow. So type casting is not needed.
|
|
|
|

GridView inner = (GridView)e.Row.FindControl("inner");<br />
DataRowView dro = (DataRowView)e.Row.DataItem;<br />
if (Session["dt1"] != null)<br />
{<br />
if (inner != null)<br />
{<br />
DataTable dt = (DataTable)Session["dt1"];<br />
DataRowView drowv = (DataRowView)e.Row.DataItem;<br />
DataRow[] dr = (DataRow[])dt.Select("No=" + dro.Row.ItemArray.GetValue(0).ToString());<br />
inner.DataSource = dr;<br />
inner.DataBind();<br />
}<br />
}
Am i doing right to bind the data ?

stll there is an error
DataBinding: 'System.Data.DataRow' does not contain a property with the name 'Itemno'.
this column name exist in the table.
Following is the code
<br />
GridView inner = (GridView)e.Row.FindControl("inner");<br />
DataRowView dro = (DataRowView)e.Row.DataItem;<br />
if (Session["dt1"] != null)<br />
{<br />
if (inner != null)<br />
{<br />
DataTable dt = (DataTable)Session["dt1"];<br />
DataRowView drowv = (DataRowView)e.Row.DataItem;<br />
DataRow[] dr = dt.Select("No=" + dro.Row.ItemArray.GetValue(0).ToString());<br />
inner.DataSource = dr;<br />
inner.DataBind();<br />
}<br />
}

You don't use a property called 'Itemno' in this code. Did you try using a debugger ? Do you know which line has the error ? I doubt it's one of these...

casting may require for columns, but for rows you wont need it

IDataObject iData = System.Windows.Forms.Clipboard.GetDataObject();
Clipboard.SetDataObject(panel1.Controls);

You can use the DrawToBitmap method on your panel, and then copy your bitmap into the clipboard. Copying a control into the clipboard, copies the control. Not a picture of it.

use CellEndEdit or CellValueChanged event, and increase the column index
private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
int Cindex = e.ColumnIndex + 1;
dataGridView1[Cindex, e.RowIndex].Selected = true;
}
hope this will help
