c# split multi-line postal address

I have a multi-line postal address (string PostalAddressString) like this:

Address1:12 Garden Street
Address2:
Suburb:Abc
PostCode:123
State:BC
Country:ABCDE

In order to separate details and access them individually i need to do this:


NameValueCollection lines = new NameValueCollection();
string[] TempArray = PostalAddressString.Split(Environment.NewLine.ToCharArray());
if (TempArray.Count() > 5 || TempArray[0].ToLower() != "n/a")
{
foreach (string line in TempArray)
{
string[] parts = line.Split(':');
if (line.Length > 0)
lines.Add(parts[0].Trim(), parts[1].Trim());
}

string PostalAddressLine1String = lines.Get("Address Line 1");
string PostalAddressLine2String = lines.Get("Address Line 2");
string PostalSuburbString = lines.Get("Suburb");
string PostalPostCodeString = lines.Get("PostCode");
string PostalStateString = lines.Get("State");
string PostalCountryString = lines.Get("Country");
}

Telerik RadGrid how to bind detailtable from code behinde

Stimulsoft relax Master Detail table relationships

When I setup master detail table relationship in my report i noticed that the master records which do not have any related detail records will not be shown.

The trick is to set "Print if Detail Empty" property of the master data band to "true"

Asp.Net retrieve Web.config AppSettings in c# code behind

have a reference:

using System.Web.Configuration;

then use this code to retrieve the value:

WebConfigurationManager.AppSettings["propertyName"]

Telerik RadGrid databinding throws error when open template edit form in insert mode with boolean controls e.g. checkbox

solution is to have a corresponding GridBoundColumn, and set DefaultInsertValue="false" in the column definition

Telerik RadGrid shows second page after opening the insert form

my radgrid uses Tempalte in EditFormSettings. It current contains 2 pages of data.
When I click on Add New Record the command button on top of the grid, the edit form opens correctly in insert mode. However when I look closely at the data, it actually shows the second page, and the page number on the bottom of the grid shows "2".


The solution is to set

tsql rename table and column

--rename a table:
EXEC sp_rename 'OldTableName', 'NewTableName'
--rename a column:
EXEC sp_rename
@objname = 'TableName.OldColumnName',
@newname = 'NewColumnName',
@objtype = 'COLUMN'

c# assign values to object property by property name

Class1 obj= new Class1();
string propertyName = "name1";
string objValue = "";
Type type = obj.GetType();
PropertyInfo prop = type.GetProperty(propertyName );
prop.SetValue(obj, objValue , null);

c# aspnet download file from server side

string text1 = this.Server.MapPath("~/" + [FileFolder]);

if (System.IO.File.Exists(text2))
{
FileStream stream1 = new FileStream(text2, FileMode.Open, FileAccess.Read);
byte[] buffer1 = new byte[((int)stream1.Length) + 1];
stream1.Read(buffer1, 0, (int)stream1.Length);
stream1.Close();

//Writes the file out the Response object
Response.Clear();
Response.Buffer = true;
Response.AddHeader("Content-Disposition", "attachment;filename=\"[File Name with extension]\";");
Response.WriteFile(text2, true);
Response.ContentType = "application/x-zip-compressed";

How to query and display excel data by using ASP.NET, ADO.NET, and Visual C# .NET

found this article very helpful
http://support.microsoft.com/kb/306572/

I modified it a bit to work for me (I am using RadUpload to get the file):

// Create connection string variable. Modify the "Data Source"
// parameter as appropriate for your environment.
String sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + ruImporter.UploadedFiles[0].FileName+";" +
"Extended Properties=Excel 8.0;";

// Create connection object by using the preceding connection string.
OleDbConnection objConn = new OleDbConnection(sConnectionString);

// Open connection with the database.
objConn.Open();

// The code to follow uses a SQL SELECT command to display the data from the worksheet.

// Create new OleDbCommand to return data from worksheet.
OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM [Sheet1$]", objConn);


// Create new OleDbDataAdapter that is used to build a DataSet
// based on the preceding SQL SELECT statement.
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();

// Pass the Select command to the adapter.
objAdapter1.SelectCommand = objCmdSelect;

// Create new DataSet to hold information from the worksheet.
DataSet objDataset1 = new DataSet();

// Fill the DataSet with the information from the worksheet.
objAdapter1.Fill(objDataset1);



// Clean up objects.
objConn.Close();

tsql split full name into firstname and lastname

this script only works with combination of firstname+' '+lastname.

--firstname
SUBSTRING(fullname, 1, CHARINDEX(' ', fullname) - 1) as firstname

--lastname
SUBSTRING(fullname, CHARINDEX(' ', fullname) + 1, LEN(fullname)) as lastname

tsql split up a comma seperated string into a table with duplicate records removed

thanks to many similar sources on the web, I came up with my script, it splits up a comma seperated string into a table with duplicate records removed



IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Spliter]') AND type in (N'FN', N'IF', N'TF', N'FS', N'FT'))
DROP FUNCTION [dbo].Spliter
GO
CREATE FUNCTION Spliter(@String varchar(max), @Delimiter char(1))
returns @temptable TABLE (items varchar(max))
as
begin
declare @idx int
declare @slice varchar(8000)
select @idx = 1
if len(@String)<1 or @String is null return
while @idx!= 0
begin
set @idx = charindex(@Delimiter,@String)
if @idx!=0
set @slice = left(@String,@idx - 1)
else
set @slice = @String
if(len(@slice)>0 and (select count(items) from @temptable where items = @slice)=0)
insert into @temptable(Items) values(@slice)
set @String = right(@String,len(@String) - @idx)
if len(@String) = 0 break
end
return
end
GO


SELECT i.items FROM dbo.Spliter(@tempstring,',') AS i where items not in (select comparesource from comparesourcetable)

Stimulsoft Web Designer restrictions

found these properties quite handy when you want to give end user limited access when designing the report in web browser, especially when you want to hide the connection string credentials.

StiWebDesignerOptions.Dictionary.AllowModifyDictionary = true;
StiWebDesignerOptions.Dictionary.AllowModifyConnections = false;
StiWebDesignerOptions.Dictionary.ShowConnectionType = false;
StiWebDesignerOptions.Dictionary.AllowModifyDataSources = false;
StiWebDesignerOptions.Dictionary.AllowModifyVariables = true;


just put them before swdCustomReport.Design(report); in your code
