Flex: Popup a Window with Javascript

Posted At : May 20, 2008 3:45 PM | Posted By : David
Related Categories: Flex

I had the need to popup a browser window from my Flex application and wanted it to popup without toolbars, etc. I found some online examples that did it in different ways. Below is the solution I went with.

FlexPopup.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

   <mx:Script>
      <![CDATA[

         public function goToURLPopup(url:String,winName:String,w:int,h:int,toolbar:int,location:int,directories:int,status:int,menubar:int,scrollbars:int,resizable:int):void
         {
            var fullURL:String = "javascript:var myWin; if(!myWin || myWin.closed){myWin = window.open('" + url + "','" + winName + "','" + "width=" + w + ",height=" + h + ",toolbar=" + toolbar + ",location=" + location + ",directories=" + directories + ",status=" + status + ",menubar=" + menubar + ",scrollbars=" + scrollbars + ",resizable=" + resizable + ",top='+((screen.height/2)-(" + h/2 + "))+',left='+((screen.width/2)-(" + w/2 + "))+'" + "')}else{myWin.focus();};void(0);";
            var u:URLRequest = new URLRequest(fullURL);
            navigateToURL(u,"_self");
         }

      ]]>
   </mx:Script>

   <mx:Panel width="100%" height="100%" title="Flex Popup Example" paddingLeft="10" paddingTop="10">
      <mx:Button label="Google" click="goToURLPopup('http://www.google.com/', 'popup', 640, 480, 0, 0, 0, 0, 0, 1, 1)"/>
   </mx:Panel>

</mx:Application>

And here is my example:

Flex: Adding Your Own Context Menu Items

Posted At : May 1, 2008 8:35 AM | Posted By : David
Related Categories: Flex

Well I've been working with Flex alot more so I will hopefully be posting more things on Flex. Something I have been working on lately is adding Context Menu items to my applications. You can add as many as you'd like but I would limit them to only the essential ones. I searched online and found various examples. Here is how I did it:

FlexContextMenu.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()">

   <mx:Script>
      <![CDATA[
         [Bindable] public var cm:ContextMenu;

         private function init():void
         {
            // Create custom context menu items             var cm1:ContextMenuItem = new ContextMenuItem("Copyright © 2008 DCFusion.com");

            cm1.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT,cm1_link);

            cm = new ContextMenu();
            cm.hideBuiltInItems();
            cm.customItems = [cm1];

            application.contextMenu = cm;
         }

         private function cm1_link(evt:ContextMenuEvent):void
         {
            goToURL("http://www.dcfusion.com/blog/");
         }

         public function goToURL(urlStr:String):void
         {
            var webPageURL:URLRequest = new URLRequest(urlStr);
            navigateToURL(webPageURL, '_blank');
         }
      ]]>
   </mx:Script>

   <mx:Panel width="100%" height="100%" title="Flex Context Menu Example">
      <mx:Label text="Welcome to my Flex app!"/>
   </mx:Panel>

</mx:Application>

I added a link to my new context menu item using an event listener, but that is not necessary.

And the final product (right-click on the Flex app to see the context menu):

ColdFusion 8: Creating CAPTCHA images

Posted At : November 12, 2007 11:06 PM | Posted By : David
Related Categories: ColdFusion

I recently had a project where my customer was getting alot of spam thru a contact form. So I thought I could use some CAPTCHA on the web form to stop some spam. I knew CF8 had the functionality to create CAPTCHA images, but I didn't know how to actually implement it. So after a bit of googling, I found Ben Nadel's post on creating and validating CAPTCHA images on forms.

I will briefly go over his code and show you my final result...

ColdFusion 8: Rounded Corners & Reflection

Posted At : August 28, 2007 9:49 AM | Posted By : David
Related Categories: ColdFusion

As you may have known, Foundeo has created an Image Effects CFC that can generate image gradients, reflection, drop shadows, and some more cool effects by taking advantage of the new image features in ColdFusion 8.

Some people have been trying to replicate some of the functions this package has, especially the gradients, reflection and rounded corners functions. John Hartmann did an excellent job in replicating the reflect() and gradientMask() functions.

Jeff Coughlin also started building a CFImage Effects Plugin for FarCry based off of John Hartmann's functions. His Plugin has code to replicate the rounded corners.

Now, lets get into the code...

Search Thru a Multi-Dimensional Array

Posted At : August 24, 2007 2:38 PM | Posted By : David
Related Categories: ColdFusion

I ran into a situation today where I needed to search thru a multi-dimensional array to update quantities and total prices for backordered products coming from a query. Unfortunately ColdFusion doesn't have an ArrayFind() function like it does for structs. I did a search on CFLib and found a UDF that did the trick.

The ArrayFindByDimension() UDF allows you to pass it an array, the value to find, dimension to search and returns the numeric array position if found, 0 if not found.

Here is some of my sample code:

<cffunction name="ArrayFindByDimension" access="public" returntype="numeric" output="false">
   <cfargument name="arrayToSearch" type="array" required="Yes">
   <cfargument name="valueToFind" type="string" required="Yes">
   <cfargument name="dimensionToSearch" type="numeric" required="Yes">
   <cfscript>
      var ii = 1;

      //loop through the array, looking for the value       for(; ii LTE arrayLen(arguments.arrayToSearch); ii = ii + 1){
         //if this is the value, return the index          if(NOT compareNoCase(arguments.arrayToSearch[ii][arguments.dimensionToSearch], arguments.valueToFind))
            return ii;
      }
      //if we've gotten this far, it means the value was not found, so return 0       return 0;
   </cfscript>
</cffunction>


<cfset i = 1>

<cfset products = ArrayNew(2)>

<cfloop query="backordered">
   
   <cfset arrPos = arrayFindByDimension(products, "#backordered.product_code#", 2)>
   <cfif arrPos EQ 0>
      <cfset products[i][1] = backordered.product_id>
      <cfset products[i][2] = backordered.product_code>
      <cfset products[i][3] = backordered.order_details_quanity>
      <cfset products[i][4] = backordered.order_details_price * backordered.order_details_quanity>
      <cfset i = i + 1>
   <cfelse>
      <cfset products[arrPos][3] = products[arrPos][3] + backordered.order_details_quanity>
      <cfset products[arrPos][4] = products[arrPos][4] + (backordered.order_details_price * backordered.order_details_quanity)>
   </cfif>
</cfloop>


<cfdump var="#products#">
