Hi
I am having small problem in WMI related question.
The folowing function will accept username,password and process executable path as input parameter, and it will launch a new process in the host.and finally I will fetch Process ID and process name.
This code is working fine for the current user, that means passing username and password as null.
My requrement is I wand to run a process for a different user( with username and password)
Can any one guide me in this rehgard?
void LaunchProcess(string filename,string username,string password)
{
bool currentUser = false;
string processName = "";
uint processID = 0;
if( (username != null)&& (password != null))
currentUser = true; // LaunchProcess got username and Password.
ConnectionOptions objConnectionOptions = new ConnectionOptions();
if(currentUser ==true)
{
objConnectionOptions.Username = username;
objConnectionOptions.Password = password;
}
ManagementScope objManagementScope = new ManagementScope("root\\cimv2", objConnectionOptions);
objManagementScope.Connect();
ManagementClass processClass = new ManagementClass("Win32_Process");
processClass.Scope = objManagementScope;
//Get an input parameters object for this method
ManagementBaseObject inParams = processClass.GetMethodParameters("Create");
//Fill in input parameter values
inParams["CommandLine"] = filename;
// this will execute the command.
ManagementBaseObject outParams = processClass.InvokeMethod("Create",inParams, null);
// Wait for 1 Second to start the Process
System.Threading.Thread.Sleep(1000);
// Get the Unique Process ID after Process Creation
processID = (uint)outParams["processId"];
//Query based on the received processID and get the Process Name .
ObjectQuery objObjectQuery = new ObjectQuery("Select name from Win32_Process Where ProcessID = '" + processID + "'");
ManagementObjectSearcher objMagObjSearcher = new ManagementObjectSearcher( objManagementScope, objObjectQuery );
ManagementObjectCollection objMagObjCollection = objMagObjSearcher.Get();
foreach( ManagementObject objManagementObject in objMagObjCollection )
{
if(objManagementObject["name"] != null)
processName = objManagementObject["name"].ToString();
} // foreach
}
}

Does onyone know of a way (or if it's even possible) to capture keystrokes in a C# app, regardless of wether it has focus or not.
I'm making a dock app for myself using C# and want to add keystrokes support and being a dock, it'd be more useful if it didn't have to have focus
Any ideas appreciated

And do you have a specific question about your homework assignment, or did you just want us to write it for you?

Why not just host the Crystal Report Viewer control. It does everything you need, displays the report on screen and lets you print it or export it to a third-party application.
Other than that, you could host an IE browser control and use XSLT to transform your xml file into html.

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.
