I do it all the time. Just use the EngMATLib. Actually it's on this site!
1..2..3 ways of integrating MATLAB with the .NET[^]
I can pass a string like this to make a 3x3 matrix in matlab...
using (EngMATAccess mat = new EngMATAccess())
{
mat.Evaluate("A = [ 1 2 3; 3 5 6]"));
}

Hi,
I found how convert my image in 128 colors (2^7)
This is my code :
ImageCodecInfo myImageCodecInfo;
Encoder myEncoder;
EncoderParameter myEncoderParameter;
EncoderParameters myEncoderParameters;
//chnage the filename to obtain a tif file
Console.WriteLine(rasterFileName);
int index = rasterFileName.IndexOf(".");
string rasterFileNameTif = rasterFileName.Substring(0,index);
rasterFileNameTif = rasterFileNameTif.Insert(index, ".tif");
Console.WriteLine(rasterFileNameTif);
try
{
// Get an ImageCodecInfo object that represents the TIFF codec.
myImageCodecInfo = GetEncoderInfo("image/tiff");
// Create an Encoder object based on the GUID
// for the ColorDepth parameter category.
myEncoder = Encoder.ColorDepth;
// Create an EncoderParameters object.
// An EncoderParameters object has an array of EncoderParameter
// objects. In this case, there is only one
// EncoderParameter object in the array.
myEncoderParameters = new EncoderParameters(1);
// Save the image with a color depth of 7 bits per pixel (128 colors).
myEncoderParameter = new EncoderParameter(myEncoder, 24L);
myEncoderParameters.Param[0] = myEncoderParameter;
Console.WriteLine(myEncoder);
picChart.Image.Save(rasterFileNameTif,myImageCodecInfo,myEncoderParameters);
It works with all formats input
But when I have a tif file input (I want also tif output but in 128 colors), I have an exception :
System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+.
at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams)
at displayRaster.displayRaster.ChangeRasterFormat() in c:\documents and settings\franck\mes documents\visual studio projects\displayraster\displayraster.cs:line 178
Do u know why?
Thx for replies.
Have a nice day

Hi,
I have a windows service in C# (.NET framework 1.1) running on Windows XP
PRO SP2. This service essentiallt starts a printjob watcher. Please see the code
snippet below.
queryInterval = ((SchedulerData)obj).Interval/1000;
//queryInterval=1;
this.printEventWatcher = new System.Management.ManagementEventWatcher();
this.printEventWatcher.Query = new System.Management.EventQuery("SELECT *
FROM __InstanceCreationEvent WITHIN "+queryInterval+" WHERE TargetInstance
ISA \"Win32_PrintJob\"");
string hostName = Dns.GetHostName();
this.printEventWatcher.Scope = new
System.Management.ManagementScope("\\\\"+hostName+"\\root\\CIMV2");
printEventWatcher.EventArrived+=new EventArrivedEventHandler(this.Arrived);
printEventWatcher.Start();
This service fires the EventArrived event when running as my login account.
i.e When the service is run as MaxBici and I login as MaxBici and print
documents, I see the events being fired.
But, when the service is run as NT AUTHORITY\SYSTEM (Local System account),
and I login as MaxBici and print documents the EventArrived event is not
fired.
The query interval was set to 1 second in both the above cases.
Could anyone help me with this?
What does the scope in the event watcher signify?
Isn't the data in the WMI tables visible to all users in a PC?
Thanks in advance.
Max

Is it possible to open a printer directly connected to the "Lpt:" port on a Windows XP system? I have a form that must be set up exactly on an old dot-matrix printer, and then printed after filling in some values. I would like to open the printer and send ASCII characters to the device.
Is this possible???
Thanks

Hi.
---------
System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.Arguments = @"C:\file.txt";
p.StartInfo.FileName = "print ";
p.StartInfo.CreateNoWindow = true;
p.Start();
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();

Thanks Serdar,
This looks like the file is printed through the spooler. Is this the best I'll be able to do with Windows XP? Write to a file and print via the spooler.
Thanks again for your help,

That's great, i can get the pc to log the user off no problems but im still having problems rebooting it. I know why, i dont know how to set the privileges for the current process.
The calling process must have the SE_SHUTDOWN_NAME privilege
I'm reading through the MSDN docs trying to figure it out but the only one i've found so far is written using C++ code, and the classes are not the same in C#. If you could help me set the privileges that would be great!
Cheers
Kev

I'd suggest you taking a look at www.pinvoke.net and convert the appropriate API calls by yourself.
This should help you a bit.
I've not done this in C# myself yet.

Got it sorted now, thanks.
Found an article that had already converted the API calls to C# and used them.
Cheers
