1.1 Understanding the Control Structure


Control structures in programming languages ​​is the command of the form (structure) that is used to set specific (control) the course of the program.



Visual Basic 6 recognizes two types of control structures, namely:

1. Decision control structures - used to decide a program code, which will be done based on a condition.

2. Repetition control structures - used to perform the repetition code. Will be discussed in the next chapter.



There are two forms of decision control structures, namely:


1. IF ... THEN structure.


2. SELECT ... CASE structure.


Forms of writing (syntax) IF ... THEN structure, are as follows:


1. IF THEN
If is True then the will be done.
END IF

2. IF THEN

Create Upload File On Server

To be able to follow this tutorial, you can be sure the web server to handle file uploads. My advice, use XAMMP.
To verify, open the following URL: localhost / xammp then click the phpinfo () that exist on the left. There will be seen that the value file_upload is ON.
Now we must first learn to create a form that is used to upload files. On creating a form that is ready to upload, you must add the attribute enctype = "multipart / form-data". To make the file size restrictions, use a hidden variable that is named MAX_FILE_SIZE and express it in bytes.

<html>
<head>
<title>From Upload</title>
<body>
Please upload your file
<br/>
Makximum size is 1 Mb<br/>
<form enctype="multipart/form-data" action="upload.php" method="post">
<input type="hidden" name="max_file_size" value="1048576">

Pilih file yang akan di upload:
<input name="userfile" type="file"> <br/>
<input type="submit" value="send file">
</form>
</body>
</html>

In listing 2, Perhtikan that the folder used to store uploadharus be writable by the server. If you use another operating system like Linux. adjust the writing style storage folder with the following, / upload or / home / user / upload.
The following listing and coding of two to manage file uploads:

<html>
<head>
<title>Upload file</title>
</head>
<body>
<?php $lanjut = 0;
switch($_FILES['userfile']
['error'] {
case 0;
echo "Upload Success"
$lanjut = 1;
break;
case1:
echo "file exceeds the specified limits"
break;
case 2:
echo "file exceeds the specified limits"
break;
case 3:
echo "only some files, which successfully uploaded"
break;
case 4:
echo "no file was uploaded"
break;
case 5:
echo "there is a problem on the server"
break;
}
if ($lanjut = 1) {
?>

<br/> <br/>
Following information from the file successfully uploads
<br/><br/>
Name File : <?php echo $_FILES['userfile'] ['name']?> <br/>
Type file : <?php echo $_FILES['userfile'] ['type']?> <br/>
Size file : <?php echo $_FILES['userfile'] ['size']?> bytes.

<?php
$upload_filename = 'E:\\ UPLOAD\\" . $_FILES['userfile' ['name'];
copy($_FILES['userfile']['tmp_name'],$upload_filename);
}
?>
</body>
</html>

Good luck.
