Try the one listed in webservicex.com. It didn't work 100%, but worked reasonably for a free service (atleast here in India).

Please don't cross-post in multiple forums. It's considered very rude.
And posting VB code in a non-VB forum open you up for.... well.... let's just say, it's not pleasent.

Hi,
I'm trying to call the Matlab engine API from C# in an ASP.net web application. To start with, I built a simple C# console app (see below), based on www.codeproject.com/samples/matlabeng.asp and it works fine.
But when I try the same thing in an ASP.net web application (I try and initialise the engine in the Application_Start method in the global assembly), I can't seem to open a connection to the Matlab engine. The engine handle after the engOpen() call is still null.
I'd welcome any suggestions for things to try.
----------------------
using System;
using System.Runtime.InteropServices;
namespace ConsoleApplication1
{
//P/Invoke wrapper for a couple of functions from matlab's libeng.dll
class Matlab
{
[DllImport("libeng.dll")]
public static extern IntPtr engOpen(string s);
[DllImport("libeng.dll")]
public static extern IntPtr engClose(IntPtr e);
//try out some other win32 dll
[DllImport("user32.dll", CharSet=CharSet.Auto)]
public static extern int MessageBox(int hWnd, String text, String caption, uint type);
}
//test class to exercise the matlab engine wrapper
class Class1
{
[STAThread]
static void Main(string[] args)
{
IntPtr engine;
engine = Matlab.engOpen(null);
//Matlab.MessageBox(0, "Hello World", "Platform Invoke Sample", 0);
Matlab.engClose(engine);
}
}
}

Hello!
I myself am new and haven't done WinForms yet, but are you having problems with MessageBox.Show ?
|
|
|
|

i seem to be having problems and can't find anywhere which explains this situation well. basically i have a datalist where currently the user can change the first name of the "member" so when they click on edit the textbox comes up to handle that. now i'm stuck on the update portion. heres what i have, i think i'm way off... help!
<br />
public void Update_User(object sender, DataListCommandEventArgs e)<br />
{<br />
<br />
string txtCustFirstNameEdit = ((TextBox)e.Item.FindControl("txtUserFirstNameEdit")).Text;<br />
string UserKey = userList.DataKeys[e.Item.ItemIndex].ToString();<br />
<br />
message.Text = UserKey;<br />
<br />
<br />
OleDbConnection userListConnection = new OleDbConnection(@"Provider....);<br />
<br />
StringBuilder custUpdateBuild = new StringBuilder();<br />
custUpdateBuild.Append("UPDATE custInfo SET custFirstName = ('");<br />
custUpdateBuild.Append(txtCustFirstNameEdit);<br />
custUpdateBuild.Append("') WHERE ID= ('");<br />
custUpdateBuild.Append(UserKey);<br />
custUpdateBuild.Append("')");<br />
string oleUpdateString = custUpdateBuild.ToString();<br />
OleDbCommand userUpdateCommand = new OleDbCommand();<br />
userUpdateCommand.CommandText = oleUpdateString;<br />
userUpdateCommand.Connection = userListConnection;<br />
userListConnection.Open();<br />
userUpdateCommand.ExecuteNonQuery();<br />
userListConnection.Close();<br />
<br />
userList.EditItemIndex = -1;<br />
userList.DataBind();<br />
}<br />
also should i be using the dataset at all? any help would be appreciated.

hi,
can we use two diffrent namespaces one after another within a single C# programs, for example something like following code..
<br />
Using system1;
Using system2;
<br />
namespace custom_namespace<br />
{<br />
class myclass<br />
{<br />
}<br />
<br />
}<br />
<br />
<br />
Is it possible?????????
thanks to you all

You mean like this:
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Threading;
namespace Number_Puzzle_Cs
public class frmMain : System.Windows.Forms.Form
{...
Of course it is! Have you looked at the top of your Form code after creating a new Windows Form project? By default, it uses 6 namespaces:
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace WindowsApplication5

Yuk! But it's free, so I guess it's worth it!

Not very pretty but as was pointed out, it works. If you can't afford VS.NET or don't want to buy it may I humbly suggest Sharp Develop[^]. It's a free .NET development enviroment. I haven't used version 1 or whatever they are up to now but I did use it back in the .6 or .5 days and it was pretty good.
Just a suggestion and it is free (both the suggestion and the app).

You might try Mono, or the C# plugin for Eclipse, these are free and pretty powerful.

Hi Dear, You can use a lot of namespaces if you want, but you must note that if there are two classes with the same name in two namespaces, You must write full address of your classs in your source code:
For example:
Suppose that you have two class with the name of Class1 in two namespaces (namespace1, namespace2) so if you want to use these class in your source code, You must write:
Public Class2
{
public void SomeFunction()
{
namespace1.Class1 object1 = ...;
namespace2.Class1 object2 = ...;
}
}
I hope these notes be enough for you.

Does anyone know how i would retrieve stored images from my access
database(I've stored them as OLE objects) and then bind the retrieved image
to an Image Control?
Also, How would i retrieve an image from a specific row using the
SelectedIndexChanged event?...I'm thinking that i need to use some sort of
array.
Thanks in advance,
Alex

It's generally better to store the path to an image file in the database because it's faster to access and causes less of a burden on the database. This is especially important for Access databases that are file-based and where space isn't reclaimed as efficiently as server-based RDBMS's.
If you must store the image in the database, then you declare a binary field type in the database. To retrieve it, you would code something similar to the following:
public Image GetImage(long id)
{
using (OleDbConnection conn = new OleDbConnection(connectionString))
{
using (OleDbCommand cmd = conn.CreateCommand())
{
cmd.CommandText = "SELECT image FROM Images WHERE ID = ?";
cmd.Parameters.Add("ID", OleDbType.Integer).Value = id;
using (OleDbDataReader reader = cmd.ExecuteReader())
{
long length = reader.GetBytes(0, 0, null, 0, 0);
byte[] buffer = new byte[length];
length = reader.GetBytes(0, 0, buffer, 0, length);
if (buffer.Length == length)
{
using (MemoryStream ms = new MemoryStream(buffer))
{
Image img = Image.FromStream(ms);
return img;
}
}
}
}
}
}
return null;
}To insert one it's also quite simple:
public void AddImage(Image img, ImageFormat format)
{
using (MemoryStream ms = new MemoryStream())
{
img.Save(ms, format);
using (OleDbConnection conn = new OleDbConnection(connectionString))
{
using (OleDbCommand cmd = conn.CreateCommand())
{
cmd.CommandText = "INSERT INTO Images VALUES(?)";
cmd.Parameters.Add("image", OleDbType.Binary).Value = ms.GetBuffer();
cmd.ExecuteNonQuery();
}
}
}
}

I would like to generate a random number between 1 and 20. My code does not seem to start at 1 as I expect. I suspect that the code I wrote might either start with a zero or might hit 21, since I get an error message. Would appreciate corrections to my code with different approaches.
Random rnd = new Random();
int randomNumber = (int)((rnd.NextDouble * 20) + 1);
Thanks

The Random instance should be seeded as well, to get a truly random sequence ( or as close as you could hope, obviously :P )
yes, if you get a number from 0 to 20 and add one, you will get a range of 1-21. Try maybe something like this:
System.Random rnd = new System.Random(DateTime.Now.Ticks);
int randonNumber = (int)rnd.Next(1, 20);

Thanks, Christian. I knew that I was doing SOMETHING wrong. While I knew that seeding was involved somewhere, and that it was possible to do it with the system clock, I wasn't certain how to proceed. I had also used a double and casted it to an integer. Probably not the best approach, I'll admit. Once again, I appreciate the insight.

Glad to help

Well actually, the call to the default constructor uses the system time as the seed, so your code to initialize with DateTime.Now.Ticks is really not necessary.

Two small annotations:
1. You don't have to cast the result of the Random.Next method cause it already returns an integer.
2. The maxValue has to be 21 cause the returned integer will be less than maxValue.

2. The maxValue has to be 21 cause the returned integer is less than maxValue.
3. It doesn't hurt to explicitly initialize the Random object with a seed, although it isn't mandatory as stated by the other poster. Also you should think about using a fixed seed to always generate the same, reproducible random number sequence.
Random rnd = new Random(DateTime.Now.Ticks);
Random rnd = new Random(1);
int randomNumber = rnd.Next(1, 21);

Hi, given an Active Directory account as well as a Exchange MailBox can
anyone show me how I link the two together in C# code?
I want to be able to (Given a persons Active Directory Username) retrieve
their details from Exchange.
I know that I must use the msExchMailboxGuid in Active Directory and link it
to the MailboxGUID in Exchange.
When I view the msExchMailBoxGuid property I receive a GUID like
{B8220D80-4788-44D6-83C3-2C421BA7D0BC}
When I call the MailBoxGUID I receive a System.Byte[]. I think that if I
cast the array to a string I might get a match between the two but I am not
sure how to do the ByteArray cast.
Thanks in advance for any ideas
Mark
