Image Uploader 4.0 for ActiveX - What features and improvements would you like to see in it?

For us the key things are ease of use and reliability. We love the feature set and in fact some features we wouldn't use like the quality bars and a few are nice-to-have like the rotation feature.

But where the rubber really meets the road for us are, (1) will users find it intuitive to use; (2) will it work on their machines without them sending us support email; and (3) will the upload speed satisfy them.

The current Java version has a couple of showstopper bugs for us that onethumb posted in another thread. If 2.0 (Java) and 4.0 (ActiveX) are reliable, we'll be happy campers.

I agree with you, please test the Release Candidate in the end of week and give us us your feedbacks.

Could you be more detailed about showstopper bugs?

Please try now. It has disappeared several hours ago only and now I have fixed it.

Uninstall version 3 from my client

Rename version 4 iuembed.js to ImageUploaderEmbed4.js

Rename version 4 ImageUploader.jar to ImageUploader4.jar

Set my internal <script> block to point to ImageUploaderEmbed4.js

Replace _isWinIE with __browser.isWinIE

The java version seems to work fine and doesn't even give me a trial version warning (it must be working with my license key). The ActiveX version will not respond to any scripting. It seems to instantiate properly with all of my .addParam() calls, but any block that calls getImageUploader() does not get the object back. Even after the following block:

if (__browser.isWinIE)
	oUploadCtl = new ImageUploaderWriter("UploadCtl", document.body.clientWidth - 30, document.body.clientHeight - 180);
else
	oUploadCtl = new ImageUploaderWriter("UploadCtl", window.innerWidth - 30, window.innerHeight - 180);

oUploadCtl.activeXControlCodeBase = "/ImageUploader4.cab";
oUploadCtl.activeXControlVersion = "4,0,9,0";
oUploadCtl.javaAppletCodeBase = "/";
oUploadCtl.javaAppletCached = true;
oUploadCtl.javaAppletVersion = "2.0.0.0";

If I call alert(oUploadCtl.version()) I get a response in Firefox, but an error in IE because the method is not supported.

Could you send us the link or post the entire source code of your page. In fact ImageUploaderWriter doesn't have version() method property. ActiveX version has Version property, but not method, so it should be called without parentheses.

I also get the error with any of the .get functions or .set methods as well. The initial configuration seems to take, but I can't script anything on the control. I'll dig up the code when I get in tomorrow.

Image Uploader for ActiveX doesn't have set/get methods actually. Instead of them it has true properties. So actually you can use:

getImageUploader("UploadCtl").FolderPaneHeight = getImageUploader("UploadCtl").height / 2.2;

instead of:

getImageUploader("UploadCtl").setFolderPaneHeight(getImageUploader("UploadCtl").height / 2.2);

However in Java there is no support of properties, so we have to use set/get methods. In order to unify the API of ActiveX and Java versions we expand in runtime the ActiveX object with set/get methods. In iuembed.js you can find the following code for it:

//Create set/get expando methods for ActiveX
function _createExpandoMethods(id){
	var o=document.getElementById(id);
	var props=new Array();
	for (propName in o){
		var c=propName.charAt(0);
		if (c==c.toUpperCase()){
			props.push(propName);
		}
	}
	for (i=0;i<props.length;i++){
		//Check whether property is indexed
		if (typeof(o[props[i]])=="unknown"){
			eval("o.set"+props[i]+"=function(i,v){this."+props[i]+"(i)=v;};");
			eval("o.get"+props[i]+"=function(i){return this."+props[i]+"(i);};");
		}
		else{				
			eval("o.set"+props[i]+"=function(v){this."+props[i]+"=v};");
			eval("o.get"+props[i]+"=function(){return this."+props[i]+"};");
		}
	}	
}

This function is called on fullPageLoad event, and only after it you can access to Image Uploader via set/get methods. We have implemented it such way as only after fullPageLoad event you can be sure that ActiveX control, Java applet, and all elements on page are loaded. For example, when you use Java version, the window.onload event fires before the applet loading, and getImageUploader("") function call at that time will return the reference to the uninitialized instance.

In you code the AID_OnChange event handler is called before fullPageLoad event fire, so get/set methods are unavailable in it.

To fix it I have added uploadCtl variable, which refers to intialized Image Uploader instance (not to ImageUploaderWriter one as oUploadCtl).

Then I have added fullPageLoad event handler:

function UploadCtl_fullPageLoad(){	
		uploadCtl=getImageUploader("UploadCtl");
		//alert(uploadCtl);
	}

//........................
											
oUploadCtl.fullPageLoadListenerName = "UploadCtl_fullPageLoad";
oUploadCtl.writeHtml();

And add checking whether contorl is initialized in AID_OnChange function:

	function AID_OnChange(cbo) {
		if (uploadCtl){
			//getImageUploader("UploadCtl").RedirectUrl = "http://test.localhost.com/ViewAlbum.asp?AID=" + cbo.options[cbo.selectedIndex].value;
			getImageUploader("UploadCtl").setRedirectUrl("http://test.localhost.com/ViewAlbum.asp?AID=" + cbo.options[cbo.selectedIndex].value);
			sRedirectURL = "http://test.localhost.com/ViewAlbum.asp?AID=" + cbo.options[cbo.selectedIndex].value;
		}
	}

The same changes was done in Body_OnResize function.

See the attachement for entire code and please let me know whther you have any questions or problems.

File Attachment(s):

UploadComponent.zip (5kb) downloaded 210 time(s).

if (_isWinIE)
   oUploadCtl = new ImageUploaderWriter("UploadCtl", document.body.clientWidth - 30, document.body.clientHeight - 180);
else
   oUploadCtl = new ImageUploaderWriter("UploadCtl", window.innerWidth - 30, window.innerHeight - 180);

I need to clear that ImageUploaderWriter is not Image Uploader object/applet. It is just Image Uploader HTML writer, and further you need to get control/applet instance using getImageUploader function. So you can call addParam method of ImageUploaderWriter only, but can not call its set/get methods. That's why I have used oUploadCtl variable for ImageUploaderWriter instance, and uploadCtl for Image Uploader one.

What error do you received with my sample?
