How to call a SOAP web service in .NET 4.0 C# without using the WSDL or proxy classes

If you want to call a .NET 4.0 C# web service, without using the WSDL or “Add Service Reference” in Microsoft Visual Studio 2010. You can use the following functions:

/// <summary>
/// Execute a Soap WebService call
/// </summary>
public override void Execute()
{
    HttpWebRequest request = CreateWebRequest();
    XmlDocument soapEnvelopeXml = new XmlDocument();
    soapEnvelopeXml.LoadXml(@"<?xml version=""1.0"" encoding=""utf-8""?>
<soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"">
<soap:Body>
    <HelloWorld3 xmlns=""http://tempuri.org/"">
        <parameter1>test</parameter1>
        <parameter2>23</parameter2>
        <parameter3>test</parameter3>
    </HelloWorld3>
</soap:Body>
</soap:Envelope>");

    using (Stream stream = request.GetRequestStream())
    {
        soapEnvelopeXml.Save(stream);
    }

    using (WebResponse response = request.GetResponse())
    {
        using (StreamReader rd = new StreamReader(response.GetResponseStream()))
        {
            string soapResult = rd.ReadToEnd();
            Console.WriteLine(soapResult);
        }
    }
}
/// <summary>
/// Create a soap webrequest to [Url]
/// </summary>
/// <returns></returns>
public HttpWebRequest CreateWebRequest()
{
    HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(@"http://dev.nl/Rvl.Demo.TestWcfServiceApplication/SoapWebService.asmx");
    webRequest.Headers.Add(@"SOAP:Action");
    webRequest.ContentType = "text/xml;charset=\"utf-8\"";
    webRequest.Accept = "text/xml";
    webRequest.Method = "POST";
    return webRequest;
}

Result
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><HelloWorld3Response xmlns="http://tempuri.org/"><HelloWorld3Result>test</HelloWorld3Result></HelloWorld3Response></soap:Body></soap:Envelope>

You can use complex types in you’re request. I use fiddler to get the contents of the soap envelope.

Checking Excel file is open or not in (In Shared mode also)

 Below is the code ,where i am checking a specified file is opened or not and if opened i am closing or else deleting.

There is no built in functionality in .Net to check ISFILEOPEN.
So we are forcebily trying to read the ,so if its not opened it will through a exception & there we can write the code for if file is not opened.
Using f As New IO.FileStream("C:\1.xlsx", FileMode.Open, FileAccess.ReadWrite, FileShare.None)

If the  file is in shared mode we have to check as below
Using f As New IO.FileStream("C:\1.xlsx", FileMode.Truncate, FileAccess.ReadWrite, FileShare.None)

Filemode.truncate will check it in shared mode.


  Dim thisFileInUse As Boolean = False
            If System.IO.File.Exists("C:\1.xlsx") Then
                Try
                    Using f As New IO.FileStream("C:\1.xlsx", FileMode.Open, FileAccess.ReadWrite, FileShare.None)
                        ' thisFileInUse = False
                    End Using
                    IO.File.Delete("C:\1.xlsx")
                Catch

                    thisFileInUse = True
                    nFiles = excel.Workbooks.Count
                    For iVar = 1 To nFiles
                        If UCase(excel.Workbooks(iVar).Path & "\" & excel.Workbooks(iVar).Name) = UCase("C:\1.xlsx") Then
                            excel.Workbooks(iVar).Close()

                        End If
                    Next
                End Try
            End If

SQL Bulk Update from Excel

Below is the sample code in C# for bulk upload of data from excel to Sql Server table.

Steps:

1-Write connection string for Sql Database

2-Coonection string for Excel sheet

3-Query to get required Data from excel sheet

4-If we need specific data from excel sheet then we can mention as FROM [Sheet1$A3:o12],So that it will read from A3 upto o12

5-Fille that data into one dataset

6-If need to do any filteration on the excel data we can do on that dataset using dataview rowfilter

7-Using column mapping ,fill the excel data into sql database table

8-Column mapping is required to specify the excel column name to Sql table column name

9-Destination table name should be specified .

Access problem while Copying & moving content of a file from one folder to another folder

Hi All,


This below code is to read the content of a file & moving that file from one folder to another folder
in vb.net.







Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.ClickDim di As New IO.DirectoryInfo("D:\Test")Dim diar1 As IO.FileInfo() = di.GetFiles()Dim dra As IO.FileInfoDim fs As System.IO.FileStreamDim sr As StreamReaderDim line As String = ""

LineCount += 1
End Whilefs.Close()

Access problem while Copying & moving content of a file from one folder to another folder is solved  if we use filestream to create a file .

End Sub

Sql Server 2008 Database Diagrams

SQL Server Database Diagram is visual model of a database. We can use only Tables in SQL Server database diagrams. Any changes made outside Database Diagram designer will reflect automatically in the diagram and vice versa.

We can create them using built-in SQL Server Database Diagram designer tool in SQL Server Management Studio. There is no Undo and Redo option, so we need to be careful when deleting columns or removing relationships

Database Diagrams are stored in dbo.sysdiagrams system table in the database we are creating diagram. This table will be created automatically, when we create the first database diagram in the database.

we can copy the diagram by copy the data of dbo.sysdiagrams table from source database to destination database, but the tables in the diagram should exist in the destination database or else while viewing or modifying the diagram, we will get the below error and corresponding tables will be removed from the diagram
“Table(s) were removed from the diagram because privileges were removed to these table(s) or the table(s) were dropped.

Query to copy database diagrams
INSERT INTO [DESTINATIONDB].[dbo].[sysdiagrams]
([name]
,[principal_id]
,[version]
,[definition])
SELECT [name]
,[principal_id]
,[version]
,[definition]
FROM [SOURCEDB].[dbo].[sysdiagrams]

For copying to remote servers, we can use Linked Servers and use Four part name or use SSIS to transfer data

We can use “Edit -> Copy Diagram to Clipboard” or “Database Diagram – Copy Diagram to Clipboard” menu option to copy the diagram and then paste it in the document required. If the diagram is bigger, we can paste it to Paint Brush or any image editor and then select specific portions and copy one by one in document.
We can also the print the database diagram as PDF, if we have PDF Print drivers such as BioPDF or CutePDF installed.

Feasible way to convert SQL Server to Oracle Store procedure

Using Oracle SQL Developer, We can convert any 3^rd party SQL procedures into Oracle (PL/SQL)

Sample Example (Convert SQL Server procedure into Oracle) as shown below

Step 1; we have the option in Oracle SQL Developer using Migration menu.

From Migration menu, select Translation Scratch Editor

Refer screen shot below:

Step 2; Get SQL Server stored procedure

Copy the stored procedure from SQL SERVER into Scratch Editor window (3rd party SQL window)

Step 3; Translate SQL Server procedure into oracle

Select translate option as shown below

We can convert any other 3^rd party sql procedure (like Access SQL to Oracle, Sybase Sql to Oracle and SQL Server T-Sql into Oracle (PL/SQL)).

Step4: Output

The procedure automatically translates from SQL procedure into Oracle (PL/SQL) procedure.

Comparison Between Candidate Key & Surrogate Key

A very good artical On candidatekey & Surrogate Key in Sql Databse.

Candidate  key is an attribute or a combination of attributes that uniquely identifies each row in the table .


Surrogate Key is  an artificially generated unique identifier, which has no relation to the table data .
 A key with no business meaning .
