// Reads the entire contents of a text file into a string variable.
// The 2nd arg specifies the character encoding used for

Send MHTML Email

TCP/IP Socket Connect to Remote Host:Port

2009-05-31T07:50:00.000-07:00

#include

void ChilkatSample(void)
{
HCkSocket socket;

BOOL ssl;
long maxWaitMillisec;
const char * receivedMsg;

socket = CkSocket_Create();

success = CkSocket_UnlockComponent(socket,"Anything for 30-day trial");
if (success != TRUE) {
printf("Failed to unlock component\n");
return;
}

// Connect to port 5555 of localhost.
// The string "localhost" is for testing on a single computer.
// It would typically be replaced with an IP hostname, such
// as "www.chilkatsoft.com".

ssl = FALSE;

maxWaitMillisec = 20000;
success = CkSocket_Connect(socket,"localhost",5555,ssl,maxWaitMillisec);
if (success != TRUE) {
printf("%s\n",CkSocket_lastErrorText(socket));
return;
}

// Set maximum timeouts for reading an writing (in millisec)
CkSocket_putMaxReadIdleMs(socket,10000);
CkSocket_putMaxSendIdleMs(socket,10000);

// The server (in this example) is going to send a "Hello World!"
// message. Read it:

receivedMsg = CkSocket_receiveString(socket);
if (receivedMsg == 0 ) {
printf("%s\n",CkSocket_lastErrorText(socket));
return;
}

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
CkSocket_Close(socket,20000);

printf("%s\n",receivedMsg);

CkSocket_Dispose(socket);

}

To accomplish this in pseudocode we write the following:

2009-05-31T07:47:00.000-07:00

procedure bubbleSort( A : list of sortable items ) defined as:
n := length( A )
do
swapped := false
n := n - 1
for each i in 0 to n - 1 inclusive do:
if A[ i ] > A[ i + 1 ] then
swap( A[ i ], A[ i + 1 ] )
swapped := true
end if
end for
while swapped
end procedure

Build Google IG like Ajax

2009-05-31T07:11:00.000-07:00

public UserPageSetup NewUserVisit( )

{

var properties = new Dictionary();

properties.Add("UserName", this._UserName);

var userSetup = new UserPageSetup();

properties.Add("UserPageSetup", userSetup);

WorkflowHelper.ExecuteWorkflow( typeof( NewUserSetupWorkflow ),

properties );

return userSetup;

}

var db = new DashboardData(ConnectionString);

var newPage = new Page();

newPage.UserId = UserId;

newPage.Title = Title;

newPage.CreatedDate = DateTime.Now;

newPage.LastUpdate = DateTime.Now;

db.Pages.Add(newPage);

db.SubmitChanges();

NewPageId = newPage.ID;

var page = db.Pages.Single( p => p.ID == PageId );

page.Title = PageName;

db.SubmitChanges();

Here only one row is selected.

You can also select a single value:

Collapse

var UserGuid = (from u in db.AspnetUsers

where u.LoweredUserName == UserName &&

u.ApplicationId == DatabaseHelper.ApplicationGuid

select u.UserId).Single();

And here's the Projection I was talking about:

Collapse

var users = from u in db.AspnetUsers

select { UserId = u.UserId, UserName = u.LoweredUserName };

foreach( var user in users )

{

Debug.WriteLine( user.UserName );

}

If you want to do some paging like select 20 rows from 100th rows:

Collapse

var users = (from u in db.AspnetUsers

select { UserId = u.UserId, UserName = u.LoweredUserName }).Skip(100).Take(20);

foreach( var user in users )

{

Debug.WriteLine( user.UserName );

}

If you are looking for transaction, see how simple it is:

Collapse

using( TransactionScope ts = new TransactionScope() )

{

List pages = db.Pages.Where( p => p.UserId == oldGuid ).ToList();

foreach( Page page in pages )

page.UserId = newGuid;

// Change setting ownership

UserSetting setting = db.UserSettings.Single( u => u.UserId == oldGuid );

db.UserSettings.Remove(setting);

setting.UserId = newGuid;

db.UserSettings.Add(setting);

db.SubmitChanges();

ts.Complete();

}

public UserPageSetup LoadUserSetup( )

{

var properties = new Dictionary();

properties.Add("UserName", this._UserName);

var userSetup = new UserPageSetup();

properties.Add("UserPageSetup", userSetup);

WorkflowHelper.ExecuteWorkflow( typeof( UserVisitWorkflow ),

properties );

return userSetup;

}
