Re: quest - ASP.NET Discussion Boards

The stuff I have done with MSMQ it seems to make the most sense to use multiple queues for back and forth communcation. So you know which queue is incoming to the service and with queue is incoming to the client. I have some code for that where the service starts up based off an item coming into the queue.

Hi Kubben,

I had a problem with MSMQ. want to take input from the client side and perform operation on the server side and give the result back to the client.(C#)

eg.To add 2 numbers
I a writing a service for this in the server using operationcontract and then the client makes a request for this service if suppose the server is down the client request is stored in a queue when the server is on it then process the message and viceversa.....(both ways)

Please give a solution Kubben for this...

Thanks and regards

My use of the MSMQ is for inter- windows service communication and web service to window service communication. Still, the biggest issues will probably have to do with can your client app access your server that the MSMQ exists on. So you need to answer some questions like. Will all the client apps be on your network? If they are then the solution is a lot easier. If they are not, then it is harder.

If you are using a sql server database or any database for that matter, you can do a similar queueing process with some sql tables. I guess you may want to think about how much work you want to do and what the benifit is of using MSMQ. I am pretty sure you are not just trying to add two numbers together.

Hi Kubben

Yes all my client applications are on the network.
i have to take input from the client process eg enter two numbers a and b and perform the callculation on the serverside and return back the result to the client .
if suppose the server is down then the client stores the message in a queue which is then retrived by the server and vice versa.

please provide me a sample code for this solution

Thanks

Well, first with the MSMQ stuff I have done the MSMQ is on the server, so if the server is down so would the MSMQ. Now if you are taking about a process that is running on the server is down that is different. You don't want to put the MSMQ on the client since you could have different PCs. I believe there is a way to hook up multiple MSMQ together, but I have not done that.
First you need to set up the MSMQ on your server. If MSMQ is not installed you will need to add it. It is not installed by default. If you go into Add/remove programs then click on add/remove windows components
Select Application Server and then click details. Check the MSMQ check box click ok and then next and go through the wizard till it finishs.
Now that MSMQ is installed you need to create your private queue. I suggest using a namespace of the project. Something like companyname.project.module.inbound What ever server process that will be reading this queue, that user that runs that process needs to have full rights to the queue. So if you are writing a windows service, the user in the login for that windows service needs rights. Right click on the private queue and select security. Add the user and give the user full rights.
Now that your MSMQ is set up you just need to access it.
Let me know when you have the queue set up and then I will give you the code to read and write messages to the queue.

hi am trying to do display the items from database to label.when i click the NEXT button ineed to display the second record to the label .
how its posssible

Get the items in a datatable. Maintain a counter variable to count the previous and next clicks. According to the counter variable display values from datatable. Keep datatable in one session or cache.

printf("Navaneeth!!")

Suppose you have the required records in a datatable dt, you only need to iterate the row index keeping the column index constant.
The rows index value needs to be stored into a hidden field after each iteration. Below is the C# code for the default.aspx for displaying the records.

<br />
using System;<br />
using System.Data;<br />
using System.Web;<br />
using System.Web.UI;<br />
using System.Web.UI.WebControls;<br />
<br />
public partial class _Default : System.Web.UI.Page <br />
{<br />
    Cls_DBtier Cls_DBtierobj = new Cls_DBtier();<br />
    int i = 0;<br />
    DataTable dt;<br />
    protected void Page_Load(object sender, EventArgs e)<br />
    {<br />
        <br />
        Cls_DBtierobj.mvar_DBConnectionstring = Application["Connection_String"].ToString();<br />
        Cls_DBtierobj.OpenConnection();<br />
        dt = Cls_DBtierobj.getNames();<br />
        i = dt.Rows.Count;<br />
        Cls_DBtierobj.CloseConnection();<br />
        LblNames.Text = dt.Rows[0][0].ToString();<br />
        <br />
    }<br />
    protected void BtnNxt_Click(object sender, EventArgs e)<br />
    {<br />
        int index = Convert.ToInt32(HidIndex.Value);<br />
        if (index < i-1)<br />
        {<br />
            index = index + 1;<br />
            HidIndex.Value = index.ToString();<br />
            LblNames.Text = dt.Rows[index][0].ToString();<br />
        }<br />
    }<br />
}<br />

HidIndex is the hidden field, LblNames is the label for displaying the records. And BtnNxt is the button display the next record.

Cls_DBtier is class file. Below is the code for it.

<br />
using System;<br />
using System.Data;<br />
using System.Data.SqlClient;<br />
using System.Web;<br />
using System.Web.UI;<br />
using System.Web.UI.WebControls;<br />
using System.Web.UI.WebControls.WebParts;<br />
<br />
public class Cls_DBtier<br />
{<br />
    public string mvar_DBConnectionstring;<br />
    SqlConnection conn;<br />
    public void OpenConnection()<br />
    {<br />
        conn = new SqlConnection(mvar_DBConnectionstring);<br />
    }<br />
    public void CloseConnection()<br />
    {<br />
        conn.Close();<br />
    }<br />
    public SqlCommand ReturnSqlCommand(string sqlStmt)<br />
    {<br />
        SqlCommand Cmd;<br />
        try<br />
        {<br />
            Cmd = new SqlCommand();<br />
            Cmd.Connection = conn;<br />
            Cmd.CommandType = CommandType.Text;<br />
            Cmd.CommandText = sqlStmt;<br />
            return Cmd;<br />
        }<br />
        finally<br />
        {<br />
            Cmd = null;<br />
        }<br />
    }<br />
    public DataTable getNames()<br />
    {<br />
        string stt = "SELECT ename FROM employee";<br />
        SqlDataAdapter SAdaptor;<br />
        SqlCommand Cmd;<br />
        DataSet ds=new DataSet();<br />
        DataTable dt;<br />
        try<br />
        {<br />
            Cmd=ReturnSqlCommand(stt);<br />
            SAdaptor = new SqlDataAdapter(Cmd);<br />
            SAdaptor.Fill(ds);<br />
            dt = ds.Tables[0];<br />
            return dt;<br />
        }<br />
        finally<br />
        {<br />
            stt = null;<br />
            SAdaptor = null;<br />
            Cmd = null;<br />
            ds = null;<br />
            dt = null;<br />
        }<br />
    }<br />
}<br />

Hi,
Myself Smruti pursuing mca
n facing problem while doing my project the data access from table to dropdown list
can anyone solve my problem by sending me the code

smruti

Smruti,

Did you populate the required data from the database to a datasource i.e. dataset, datareader, datatable etc...

assuming you used a dataset with the data then you have to give the following code for filling the dropdownlist

dropdownlistid.datasource = datasetname;
dropdownlistid.datatextfiled = datasetname.tables[0].Columns["ColumnName"]
dropdownlistid.datavaluefield = datasetname.tables[0].Columns["ColumnName"]

Doing so the drop down list would be populated with text and respective values.

Gautham

use this in code behind
I am taking All the districts in a DataSet and binding to a drop down list

DataSet result = null;<br />
<br />
						//Kommune<br />
<br />
						result = userBll.GetKommunes();<br />
<br />
						cbKommune.Items.Clear();<br />
						cbKommune.DataSource = result;<br />
						cbKommune.DataTextField = "KOMMUNE_NAVN";<br />
						cbKommune.DataValueField = "KOMMUNE_NR";<br />
						cbKommune.DataBind();<br />
						cbKommune.Items.Insert(0,new ListItem(captions.GetString("PleaseSelectKommune"),"0"));

Hi,

I'm using a gridview control. It has a checkbox template field with an OnCheckedChanged event. How do I access row number in gridview
inside OnCheckedChanged event of my checkbox?

Thanks!!!

-- modified at 6:55 Wednesday 16th May, 2007

Gerri

Hi
Are you calling a Javascript method from code behind for the event OnCheckedChangedEvent? So you might have attached the event in run time.. Right ???

Pass ClientID of the field Checkbox as a parameter to the calling method. Then using that parameter you can easily locate a row of GridView

Hope this helps.

Harini

thank you. =)

Once you install the application via set make sure that you have a web share created for that folder. Once that is done you can use the share name to launch the application

You can very well do an XCopy create a web share and launch the application from that sharename.
