How to compile C# Application for both 32 bit and 64 bit system?

I have faced this problem when one of my client try to run SMS Suit software in Windows 7 64 bit.Previously it is working perfectly in vista and windows xp 32 bit .After searching online I have found lots of solutions on it now I want to share these with you...

Solution :1

You can edit your visual studio c# project file (.csproj) and put this snippet:
1.<PlatformTarget> x86 </PlatformTarget>

inside

2.<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">


Solution :2(Command-line form)
Using CorFlags to set the 32BIT flag on the executable. E.g:
corflags.exe myapp.exe /32BIT+

This will modify your exe, so you might wanna keep a backup just in case. You can also revert the flag using /32BIT- instead of /32BIT+.


Solution :3(Simplest way)
1.Right click your Project, and select Properties.
2.In properties, select the Build tab. Under Platform target, select x86.
3.Hit Ctrl+Shift+S to save all files, right click the Solut…

MS Sql server: How to do multiple rows insert ?

int[] val2 = new int[no_of_values];
val1[0] = val1;
val2[0] = val2;
val1[1] = val11;
val2[1] = val22;
// Do the inserts using Parameterized queries.
Connection.Open();
SqlCeCommand command = Connection.CreateCommand();
command.CommandText = "Insert INTO [Table] (col1, col2) Values (...val1, ...val2)";
for (int i = 0; i < no_of_values; i++)
{
command.Parameters.Clear(); //it needs to clear parameter after each row inserted.
command.Parameters.Add("...val1", val1[ i ]);
command.Parameters.Add("...val2", val2[ i ]);
command.ExecuteNonQuery();
}
Connection.Close();

Deprecated HTML elements /Bad Tag

There are several HTML elements and attributes that have now been declared deprecated by the World Wide Web Consortium (the organization that sets HTML standards).

'Deprecated' means that the elements no longer serve a purpose and have been replaced by other methods, mostly involving cascading stylesheets (CSS). Although it is recommended that web browsers continue to support them, eventually they will become obsolete.

Windows 7 : C# Error:'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine

Problem

Today I have faced this error when try to use MS Access database from SMS software. After goggling I have found the solution in ...
MSDN forum


Solution

The behavior you described is expected. If your application runs in 64-bit mode, all of the components it uses must also be 64-bit. There is no 64-bit Jet OLE DB Provider, so you get the message described. You would receive a similar error when trying to connect to a database using OLE DB or ODBC if there is no 64-bit version of the specified OLE DB provider or ODBC driver.
This problem only occurs in applications that run in 64-bit mode. Compiling the application so it runs only in 32-bit mode is the best current solution.
