Example to show the usage of cfchart embedded inside cfdocument.

Description: Embed a cfchart inside a cfdocument. Note: In case of cfcharts, if you want to embed a cfchart inside a cfdocument, you can use the following formats for cfchart. 1. jpg 2. png Currently, format="flash" is NOT supported.

You should have the datasource cfdocexamples(this comes by default with the installation)

<!---The following example analyzes the salary data in the cfdocexamples
database and generates a bar chart showing average salary by department. The
body of the cfchartseries tag includes one cfchartdata tag to include data that
is not available from the query. --->

<cfdocument format="pdf">

<!--- Get the raw data from the database. --->
<cfquery name="GetSalaries" datasource="cfdocexamples">
SELECT Departmt.Dept_Name,
Employee.Dept_ID,
Employee.Salary
FROM Departmt, Employee
WHERE Departmt.Dept_ID = Employee.Dept_ID
</cfquery>

<!--- Use a query of queries to generate a new query with statistical data for each department.
AVG and SUM calculate statistics. GROUP BY generates results for each department. --->
<cfquery dbtype="query" name="DataTable">
SELECT
Dept_Name,
AVG(Salary) AS avgSal,
SUM(Salary) AS sumSal
FROM GetSalaries
GROUP BY Dept_Name
</cfquery>

<!--- Reformat the generated numbers to show only thousands. --->
<cfloop index = "i" from = "1" to = "#DataTable.RecordCount#">
      <cfset DataTable.sumSal[i] = Round(DataTable.sumSal[i]/1000)*1000>
<cfset DataTable.avgSal[i] = Round(DataTable.avgSal[i]/1000)*1000>
</cfloop>

<h1>Employee Salary Analysis</h1>
<!--- Bar graph, from Query of Queries --->
<cfchart format="jpg" xaxistitle="Department" yaxistitle="Salary Average">
<cfchartseries type="cone" query="DataTable" itemcolumn="Dept_Name" valuecolumn="avgSal">
    <cfchartdata item="Facilities" value="35000">
</cfchartseries>
   </cfchart>

</cfdocument>

cfdirectory single character wild card example.

Here is an example to show the usage of cfdirectory filtering using single character wild card(?).

Description: cfdirectory manages interactions with directories.

Syntax

<cfdirectory
directory = "directory name"
action = "list|create|delete|rename"
filter = "list filter"
listInfo = "name|all"
mode = "permission"
name = "query name"
newDirectory = "new directory name"
recurse = "yes|no"
sort = "sort specification"
type = "file|dir|all">

Note: You can specify this tag's attributes in an attributeCollection attribute whose value is a structure. Specify the structure name in the attributeCollection attribute and use the tag's attribute names as structure keys.

<!--- List all files in the current directory based on the following filters:
       Get files whose filenames have only FOUR characters followed by the 'cfm' extension type. ex:test.cfm, fun1.cfm etc
--->
<cfset filters = "????.cfm">

<cfdirectory
   action="list"
   directory="#ExpandPath( '.' )#"
   filter="#filters#"
   listinfo="name"
   name="dirlist"
/>

<!--- Output file list. --->
<cfdump var="#dirlist#" label="Files with four chars">
<br>

<!--- Multiple filters:
       Get files whose filenames have only FOUR characters followed by the 'cfm' extension type. ex:test.cfm, fun1.cfm etc
       And
       Get files whose filenames have only THREE characters followed by the 'cfm' extension type. ex:fun.cfm
       And
       Get ALL files with .cfc extension. ex:app.cfc
--->
<cfset filters = "????.cfm|???.cfm|*.cfc">
<cfdirectory
   action="list"
   directory="#ExpandPath( '.' )#"
   filter="#filters#"
   listinfo="name"
   name="dirlist"
/>

<!--- Output file list. --->
<cfdump var="#dirlist#" label="Multiple Filters">
<br>

cfftp example

Posted At : May 12, 2008 12:30 PM | Posted By : Admin
Related Categories: cfftp

Here is an Example to show the usage of cfftp.

cfftp lets users implement File Transfer Protocol operations. By default, cfftp caches an open connection to an FTP server. cfftp operations are usually of two types: 1. Establishing a connection 2. Performing file and directory operations

This example opens and verifies a connection, lists the files in a directory, and closes the connection.

<!--- Open a connection --->
<cfftp action = "open"
username = "user1"
connection = "myconn"
password = "mypwd"
server = "10.192.36.229"
stopOnError = "Yes">

<!--- Did the connection succeed... --->
<cfoutput>#cfftp.succeeded#</cfoutput>

<!--- List the files in a directory... --->
<cfftp action = "LISTDIR"
stopOnError = "Yes"
name = "ListFiles"
directory = "/"
connection = "myconn">

<cfoutput query = "ListFiles">
#name#<br>
</cfoutput>

<!--- Close a connection --->
<cfftp action = "close"
connection = "myconn"
stopOnError = "Yes">

<!--- Did the close succeed... --->
<cfoutput>#cfftp.succeeded#</cfoutput>

ArrayIsDefined Example

Posted At : May 6, 2008 11:45 PM | Posted By : Admin
Related Categories: Functions

Here is an example to show the usage of ArrayIsDefined function in CF8.

This function determines whether an array element is defined.

Returns YES, if the array element is defined (exists). Returns NO, if the array element is NOT defined.

Function syntax: ArrayIsDefined(array, elementIndex)

<!--- Create a new array --->
<cfset MyArray = ArrayNew(1)>

<!--- Populate the array --->
<cfset MyArray[1] = "First Element">
<cfset MyArray[3] = "Third Element">

<!--- Display the contents of the array --->
<p>
Your array contents are:
<cfdump var="#MyArray#">
</p>

<cfoutput>
<!--- Check if the elements are defined. --->
<p>Does element 1 exist?
#ArrayIsDefined(MyArray, 1)#
<p>Does element 2 exist?
#ArrayIsDefined(MyArray, 2)#
<p>Does element 3 exist?:
#ArrayIsDefined(MyArray, 3)#</p>
</cfoutput>

Note: This function currently throws an error if the array is NOT initialized. So if the array is not yet created, you should surround the ArrayIsDefined code in a block. Also, the ArrayIsDefined function throws an error if you test for an element beyond the length of the array. To prevent this error, you can surround the test in the ArrayLen function.
