Guys,
I was able to import my excell file to my datagrid using dataset. The only problem is that the DATES "01/22/2005" in one of the colums in excell when read from dataset becomes numeric, it was converted to number with a value of 36753. When I checked the Excell format for that paricular cell it has a DATE Category.
Any one of encounter the same scenario? Any Ideas?
Thank you in advance.

I need to convert the picture on the panel to bytes.
I did that but it works only for the backgroungimage of a panel.
in my program I use 3ds max to draw on the panel
I need to convert the picture on the panel to bytes
this is the function I use to get the bytes of the backgroungimage of the panel
private void fun()
{
pna1.BackgroundImage.Save("m"); //m is the name of the file
bm = new Bitmap("m");
//the size of the panel is 240*160
byte [,] matrix= new byte [240,160];
byte red=0, green=0, blue=0;
byte [] test=new byte [1];
for (int y=0; y < 160; y++)
{
for (int x =0; x < 240; x++)
{
Color u=bm.GetPixel (x ,y);
//I need only one byte represent each pixel
blue = (byte)(u.B/64*64);
green = (byte)(u.G/32*8);
red =(byte)(u.R/32);
matrix[x,y]=(byte)(red + green + blue);
}
}
}

Hello,
i want to make an application for a touchscreen. On the first form
you'll have to enter a number and then you'll have to hop to the
next form and close the first one. How can i do this in a good way ?
A sort of wizard is what i want, can anyone give me a hint how to
realize this ?
thanks
with kind regards
Joris

You'll need a controller class popping up the Forms one by one.
This class could hold a collection of Forms to show and each form could inherit from a common base class that's responsible for showing/handling the controls to switch to the next (and perhaps previous) Form.
In your controller class itself it's just a matter of several ShowDialogs.

{
if (e.KeyChar == (char)Keys.Enter) dataGrid1.Select(dataGrid1.CurrentCell.RowNumber);
}
..and i overrided onkeypress in mydatagrid with

base.OnKeyPress (e);
}
but not working...what is missing??

Is there any ways to read directly and rapidly from a stream to an unmanaged buffer ( IntPtr or byte* ) without having to do a convertion from the byte[] to the IntPtr through Marshal.Copy method ?
More clearly, I want to avoid this Marshal.Copy :
byte[] b = new byte[1024];<br />
int size = theStream.Read(b, 0, 1024);<br />
IntPtr bufferPtr = Marshal.AllocHGlobal(size);<br />
Marshal.Copy(b, 0, bufferPtr, size);
Apparently there is a UnmanagedMemoryStream class coming along with winFx doing the job, but I'm looking for something usable with the framework 1.1
Thanks a lot,
Julien.

Here is an example of how I load a memory font from resources:
PrivateFontCollection col = new PrivateFontCollection();<br />
Stream fontStream = GetType().Assembly.GetManifestResourceStream("somefont.ttf");<br />
<br />
byte[] fontdata = new byte[fontStream.Length];<br />
fontStream.Read(fontdata,0,(int)fontStream.Length);<br />
fontStream.Close();<br />
<br />
GCHandle gc = GCHandle.Alloc(fontdata, GCHandleType.Pinned);<br />
<br />
col.AddMemoryFont(gc.AddrOfPinnedObject(),fontdata.Length);<br />
gc.Free();

That's interesting. Do you know what is actually GCHandle.AddrOfPinnedObject doing behind ? Because I'm not sure C# arrays are contiguous like C/C++ arrays are. And I profit to ask you; have you compared both methods efficiency ( GCHandle / standard Marshal.Copy ) ?
Thanks for the hint anyway

Hello,
I have written C# dlls, but not executable wrappers. I would like to wrap an executable and make it a *service*. Can anyone recommend an article or approach?
Many thanks,

I want to free up the network while the user is logged in to the machine.
Basically I will be running azurues on a machine that my family uses. They have all different logins to the machine. Mum, Dad, Sister, etc.
When I have azureus running under my account they can't browse the web becuase I am chewing up all the network. User fast switching allows my account to continue downloading through azureus ... while someone else logs in to browse the web and check their emails etc
I don't want to give them access to my account to pause/stop azurues.
I can build a small app that can talk azurues by using azurus xml over HTTP plugin. This is not a problem. But I don't want to have to have them manually stop/start azurues with this app as they may forget to restart it.
I wanted to make the whole process automated. So I was going to write a NT service that will pause azurues when a user logs in and resume download when they log off.
But I am not sure where to start looking to get the logon and logoff event.
It would be good if I could get the user id that is logging on and off So that I can select which accounts will pause azureus and which will allow it to continue running (ie my logon account).

Hello everyone!
This is my first post here! 
OK, I made some kind of music player that plays the music in a different thread... When the user clicks the "Stop" button, the thread stops, but then I can't restart the thread when the user clicks "Play" because I get a ThreadAbortException! What can I do? Thank you very much!

It's not possible to reuse aborted threads. What you can do is simply stop and wait instead of aborting the thread. Something like
void ThreadFunc()
{
while(true)
{
if (isStopped)
{
startEvent.WaitOne();
}
}
}
Regards
Senthil

No, just name the thread when you make it, then stop it, then use this trick:
[code]Thread.FreeNamedDataSlot(string name);[/code]
And then you can restart it!
Thanks for your help though!

hello
I have a question about the static class that is auto generated when you create strongly typed resources. The question is how do i make the class and properties stay public in shared resource-only assemblies, when i need to update the resources, becasue the code is auto generated when you update the resource. So the class and properties change back to internal is there a work around ????
thanks in advance

It's rarely a good idea to modify tool-generated code. Why not just make a public class that exposes the verious resources as public?

Just make a static class that exposes all your properties publicly.
static class PublicResources
{
public string SomeStr
{
get { return Resources.SomeStr;
}
}

Thanks for that bit of code that does work for the main app assembly, but how do i get it work for resource only assemblies, which are updated outside the project. I cant access the class because it is internal below is a web pag that tells me the following:
Listing 1: A static class is generated for all strongly-typed resources.
This class and its properties must be made public in shared, resource-only assemblies, in order for them to be accessible to other components as shown in Figure 2.
http://www.theserverside.net/articles/showarticle.tss?id=LocalizationPractices
this does not make sense because if you up date your resources the class and its properties change back to internal with the auto generated code tool.
Hope you can help in some way

How do I read output from another shell program (e.g. netstat --or-- dd) so I can input it into my program?
The current code I have is:
/********************
* Get the list of devices from dd.exe
********************/
System.Diagnostics.Process process1;
process1 = new System.Diagnostics.Process();
process1.EnableRaisingEvents = false;
string strCmdLine;
strCmdLine = "/C dd.exe --list > list.txt";
System.Diagnostics.Process.Start("CMD.exe",strCmdLine);
process1.Close();
My goal is to read a list of devices that it's capable of and provide a list. This program is jsut going to be a wrapper to the shell program.
Any suggestions?

Look at the ProcessStartInfo class. It has a RedirectStandardOutput property, which lets you read from the StandardOutput streamreader of the process. Then you don't have to bother with cleaning up temporary files when you are done.
