Hi all,
I want to check whether a system is connected with a LAN or not? How can i do it using .Net either VB or C#.
Second thing is after detecting the network connection i want to find the IP address OR Machine name of the Local Area Network Server. And using that LAN server IP/Name i want to listout all the machines that are connected at this moment. How can i do this?
What way i can achieve the above needs? What are the namespaces should i require to achieve these things done?
Expecting ur reply. Please anyone help me?
regards

Try the below code. You get the computer's list in a DataTable.
public DataTable GetComputers
{
DataTable dtComputers = new DataTable("Computers");
DataColumn dc;
DataRow dr;
dc = new DataColumn("ComputerName");
dc.DataType = System.Type.GetType("System.String");
dc.MaxLength = 50;
dtComputers.Columns.Add(dc);
dc = new DataColumn("IPAddress");
dc.DataType = System.Type.GetType("System.String");
dc.MaxLength = 50;
dtComputers.Columns.Add(dc);
Process p = new Process();
p.StartInfo.FileName = @"net.exe";
p.StartInfo.Arguments = "VIEW";
p.StartInfo.CreateNoWindow = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false;
p.Start();
p.WaitForExit();
while (!p.StandardOutput.EndOfStream)
{
string readLine = p.StandardOutput.ReadLine();
string computerName = "";
if (readLine.IndexOf("\\") == 0)
{
dr = dtComputers.NewRow();
computerName = readLine.Substring(2, readLine.IndexOf(" ")).Trim();
Console.Write("\n" + computerName);
dr["ComputerName"] = computerName;
dr["IPAddress"] = Dns.GetHostEntry(computerName).AddressList[0];
dtComputers.Rows.Add(dr);
}
}
if (!p.HasExited) p.Kill();
return dtComputers;
}

Hello all. I'm an intermediate programmer, but relatively new to the web end of things and was wondering about the best way to go about scheduling an occasional task to run on the server... say every day or a certain number of hours/minutes.

Windows service is good one for this.

Can you be more specific? How does one go about writing/installing a Windows service on a web server? I am hosted with 1&1, and do not have direct access to IIS.

Hi,
I have developed an ASP.Net Website,
and now I have published it,
in first page there is no code to run, only a login page but when I want to open my website in web a Runtime Error, but yet no code is runned.
it's the first time I upload an asp.net web site.
should I do any changes in my web.config for upload?
my web.config:
<?xml version="1.0"?>
<configuration>
<appSettings/>
<connectionStrings>
<add name=".." connectionString="Data Source=.;Initial Catalog=..;User ID=..;PWD=.." providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.
-->
<compilation debug="false">
</compilation>
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authentication mode="Windows"/>
<!--
The <customErrors> section enables configuration
of what to do if/when an unhandled error occurs
during the execution of a request. Specifically,
it enables developers to configure html error pages
to be displayed in place of a error stack trace.
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
</system.web>
</configuration>
Best wishes

Hi, i have a rookie question. how do i link asp.net and silverlight so that i can set properties or values on asp.net page and be able to access those values with a silverlight client?
i started a asp.net web application project. then i added a silverlight project. in asp.net, i selected "add silverlight link". at this point, i think i should be able to somehow move any data back and forth between asp and silverlight, and this is where i'm stuck. any suggestions what i can try ?
thanks !!

If you're talking about having a Silverlight object and other server controls on the same ASP.NET page, and have them share data back and forth, I think this proof of concept[^] will point you in the right direction.
If you're talking about having a silverlight component that should communicate with an ASP.NET web service, take a look at this QuickStart tutorial[^].

You can use "Add Silverlight Link" in VS 2008 if you have Silverlight Tool for VS 2008 installed.

No. You won't be able to get the properties of ASP.NET page from Silverlight project. The main reason why we should use "Add Silverlight link" is that ~
1. To prevent the cross-domain error. For example, you won't be able to access the database from Silverlight directly. So, you have to create the webservice for that. then you have to invoke that service to get the data from database. If you are using two different projects for web service and silverlight project, you will get the cross-thread.. So, what we used to do is that we put the webservice in ASP.NET project and add the silverlight link to ASP.NET project.
Let me know if you need more help on Silverlight 1.1 with ASP.NET. I'm willing to help you..

Hi
Try the Below code
you have to add one DLL or COM Obeject I dont remember exactly Named Microsoft Excel 11.0 Object
//INCLUDE
using Excel; //For Excel LOCATION DLL Microsoft Excel 11.0 Object Library
using System.Reflection; //For Missing
using System.Runtime.InteropServices; //For Marshall
//CODE:::::
Excel.Application oXL;
_Workbook oWB;
_Worksheet oSheet;
object oMissing = Missing.Value;
Range oRng;
oXL = new Excel.Application();
oWB = oXL.Workbooks.Open("EXCEL LOCATION", oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing);
int TotalSheetsinExcel = 0;
TotalSheetsinExcel = oWB.Sheets.Count - 1;
oSheet = (_Worksheet)oWB.Sheets[1];
Picture pic = (Picture)oSheet.Pictures(1);
//pic object will have PICTURE
//Close Objects
oWB.Save();
oWB.Close(null, null, null);
oXL.Workbooks.Close();
oXL.Quit();
Marshal.ReleaseComObject(oXL);
Marshal.ReleaseComObject(oSheet);
Marshal.ReleaseComObject(oWB);
GC.Collect();

private void crystalReportViewer1_Load(object sender, EventArgs e)
{
//string strcon = "Provider=SQLOLEDB;Server=./SQLEXPRESS;DataSource=rescue15; User Instance=false; Integrated Security=true;";

Hi mavii,
I too worked on Crystal Reports where I didnot do the Procedure as given by you. I used Stored Procedures which is very simple and easy to use. If you require this I will help regarding this.
|
|
|
|
|
i have not worked with stored procedure, please guide me, can u tell me the whole procedure to design crystal reports in windows application (not the web-based application)
|
|

Hi,
I worked in Web application but I think both are the same. The procedure which I did in Web Applications is:
1) First in the ASPX Page gave the required Text boxes which will give input to Stored Porcs. Upon submitting the Page I will redirect to new ASPX Page which will Display only Crystal Reports. This is because if we keep any other fields like Textboxes there will be a problem which I don't know exactly.
2) In the Second Page I will just have Crystal Reports Viewer(CRViewerPortfolioReports) and Crystal Reports Source(CRSourcePortfolioReports .
On Page Load the below code has to be written
int Portfolio_ID = int.Parse(Request.QueryString.Get("Portfolio_ID"));
//Portfolio_ID Input Parameter for Stored Procedure.
string ReportName = "CRPortfolioReports.rpt";
string ReportPath;
ReportPath = Server.MapPath("../CrystalReportFiles/") + ReportName;
//ReportPath Location of the CRYSTAL REPORT
CRSourcePortfolioReports.ReportDocument.Load(ReportPath);
CRSourcePortfolioReports.ReportDocument.SetDatabaseLogon(USERNAME, PASSWORD);
CRSourcePortfolioReports.ReportDocument.SetParameterValue("@IMRsPerPortfolio_PortfolioID", Portfolio_ID);
//@IMRsPerPortfolio_PortfolioID STORED PROCEDURE INPUT PARAMETER
//IF you want to add another Input Parameter DATE...
//CRSourcePortfolioReports.ReportDocument.SetParameterValue("@IMRsPerPortfolio_DATE", //DATE);
CRViewerPortfolioReports.ReportSource = CRSourcePortfolioReports;
CRViewerPortfolioReports.DataBind();
3) Building the CRYSTAL REPORT .rtp FILE
Add New Crystal Report File and create a new Database connection and add the Stored Procedure developed. You will automatically get the Input Parameters and Output Parameters which you could automatically map to X or Y Cordinates. Like if @IMRsPerPortfolio_PortfolioID id INPUT Parameter it will be coming in Parameters Field of Field Explorer Tab.
