My name is Christos Mavroyiorgos. At present, I’m a student at the University of Patras and I have to construct a tool and environment that someone could use in order to draw and construct charts as part of a process of designing a software system. Some examples are UML Class Diagrams, Data Flow Diagrams, and Entity Relationships Diagrams.

The technologies that I use in order to implement it are the following:

• HTML
• XHTML
• CSS
• PHP
• JavaScript
• XML
• DHTML
• DOM

It is not necessary to use all the above but most of them.

Main functionality should be that someone could Drag and Drop, Resize, etc the drawing elements.

In addition to the main functionality of drawing the charts at the client side, a model(?)and a construct should be developed (with PHP) so that the user of the tool could be able to save the graph and call it back at a later moment for editing (I think this would be server side interaction).

I would appreciate very much to know whether anyone could help me in order to carry out this project or give me hints , ideas and advise, in a step by step process, by having a close collaboration or even taking charge of the whole project and implement it on my behalf ?

In any case, I would like to hear ,as soon as possible on any conditions and terms you consider to be necessary for any kind of collaboration in order to meet the demands of a successful project.

Thanks in advance

Sincerely yours

Christos Mavroyiorgos

You say:
"...or even taking charge of the whole project and implement it on my behalf."
Christos, if you want your degree/ diploma or whatever, you really ought to earn it yourself. Asking for ideas and advice is one thing; getting someone else to do your work for you is another. If don't want to, or are not capable of, becoming a programmer, I would suggest you find some other way to earn a living.

Sorry, this isn't really my field, but I can't help wonder why you want to develop this as a web application - it sounds like it would be more suited to a desktop app, and as such could be relatively easily accomplished in Visual Studio, using VB or C# or whatever other language you like.
Use the right tool for the right job - makes all the difference!
Good luck

Wow - any sort of charting app will require some pretty complex JScript, and work on a limited subset of browsers. As such, if you're targetting IE6, why is it that you need to use PHP ? I think your teacher is an idiot. PHP is useless in the real world, that is to say, you won't be getting experience that will help you find a job.

No matter what, this is the wrong project to be implimenting as a web app.

Dynamically Positioning a layer

JKallen12-May-05 17:00

12-May-05 17:00

I am aC++ and php programmer/scriptor (sp?) but know little about javascript and the document object model. How do I dynamically find the the top and left values (IN PIXELS) of an object with respect to the top left of the browser window. I use tables to format pages so objects can have parents, grandparents, great-grandparents,..etc. The clientLeft and offsetLeft in conjunction with the offsetWidth dont give me the values I need to set the proper location. I need a way to find the position with respect to the top left corner of the client area of the IE Explorer browser window.

I have searched the msdn and am not finding the answer.
Thanks a million.

Dear CPian,

in the HTML world, all tags have a STYLE called "position". The "position" style can have a few different values. The 3 most used that you should be aware of are:

inline
absolute
relative

The default one is INLINE which allows the HTML elements to be rendered as they are found within the HTML code. In other words they follow the flow of the code in respect of their parent element.

The ABSOLUTE positioning will ignore the hierarchy for of the element(in the HTML code) to wich is applied and position the element to exact coordinates having as origin the most top and most left of the browser wndow. This is why you will notice that all asolutely positioned elements also have a LEFT and a TOP style, style attributes that take as values numbers in pixels, picas, ems and percentages and a few others that my mind is missing now. So an element coded as such:

<DIV style="position:absolute; top:100px; left:100px;">I AM ABSOLUTELY POSITIONED</DIV>

will have its origin(top left corner of the DIV) to the coordinate 100,100 discarding any parent elements. No matter where it is found within the code, its position wouldn't change.

The RELATIVE positioning is the same with the ABSOLUTE with one main difference. It uses as an origin its parent elemets top most and left most position instead of the browser top most and left most position.

Hope I helped. :P

You can try this: http://www.webdeveloper.com/forum/history/topic.php/63118-1.html[^], but keep in mind that an ActiveX object isn't necessarily going to work on all computers. Other options would be using a WShell object in VBscript (client side), but then again, it isn't going to work on all systems. If you don't need to read a lot of information, you may also want to read: http://www.sitepoint.com/article/control-internet-explorer[^].

Hi...

thanks for the information ...

actually i want to retrieve the version of ActiveX component registered on the client-side from client-side javascript code.
so i am instantiating component by calling
var obj = new ActiveXObject(name_of_component)
and then i invoke its method Get_Version() which returns me the version of component. In this Function, i can read .INI file to retrieve the version.

But the problem is that all methods of COM interface return HRESULT value, so to get version, i need to pass version parameter by address.
Now How do we pass function parameter by address in JavaScript ?

Can you help me doing that ? or any alternative way if you can think of.

Please let me know ASAP.

Thank You,
Abhi

how to draw a rectangle on an image in asp .net

Re: asp .net

Christian Graus11-May-05 19:33

Christian Graus

11-May-05 19:33

You can't do it on the client end, you need to do it on the server, and then you do it the same as you would in a WinForms app - if you're sending an image to the client, you first load it into a Graphics object and draw on it.

If you just mean put a rectangle on the form in the browser, that's a whole different ball game. Remember, your C# code exists for the sole purpose of generating HTML, all you can show on the client is what you can show in HTML, and by using JScript if you must.

Perhaps SVG would help here ?

using System.IO;

and in your event handler:

DirectoryInfo r = new DirectoryInfo("myRootPath");
r.CreateSubdirectory("MyFolder");

Of course, as you've asked in the web development area, you need to make sure that your web app has permission to create a folder at this location.

How to tell when a redirected GET has completed

andybloom11-May-05 15:28

andybloom

11-May-05 15:28

I am developing a automated web data extraction program. One of the pages (POST) gets redirected. If I disable automatic redirection and attempt a GET to the redirection page, the server does not come back with the data (timeout). If I allow the redirection to occur, when I attempt to read the data (redirection is GET) I often end up reading a partial page (the transaction has not completed).

How can I tell the transaction completed for:

pFile = pServer->OpenRequest("POST", ....
:
pFile->SendRequest(NULL,NULL,(LPSTR)(LPCSTR)post_string,post_string.GetLength());

pFile->QueryInfoStatusCode(dwRet);

if (dwRet == HTTP_STATUS_OK) { <--- the status is OK even though the redirected read is in action at the time!
pFile->Read(htm_read_buffer, BUFFER_SIZE);
}

Thanks in advance!

ServerXMLHTTP - invalid response

11-May-05 14:30

Getting "the server returned an invalid or unrecognized response" error on the code listed below. The url is an asp page on my company's qa server that takes an
xml request, processes it and returns an xml response. The code works fine
at work when run from my win 2000 machine on our LAN but one of our clients
is complaining about the above error, he's using a win xp machine. I can reproduce the error if I take the code home and run it from my xp machine but I'm not a web developer so I haven't got a clue how to make it work. I searched msdn and found a few items regarding the above error, most of it I didn't understand but some of it suggested different IE security settings which I tried to no avail.

Any advice would be appreciated ...

	var SXH_OPTION_IGNORE_SERVER_SSL_CERT_ERROR_FLAGS = 2;<br />
	var SXH_SERVER_CERT_IGNORE_ALL_SERVER_ERRORS = 13056;<br />
	<br />
	//declare some vars<br />
	var url = "someurl.asp";<br />
	var oXmlHttp = new ActiveXObject("Msxml2.ServerXMLHTTP.4.0");<br />
	var domReq = new ActiveXObject("Msxml2.DOMDocument.4.0");<br />
	<br />
	//load the request<br />
	domReq.async = false;<br />
	domReq.loadXML(document.getElementById("req").value);<br />
<br />
	//set-up for posting data<br />
	oXmlHttp.open("POST", url);<br />
	oXmlHttp.setOption(SXH_OPTION_IGNORE_SERVER_SSL_CERT_ERROR_FLAGS,SXH_SERVER_CERT_IGNORE_ALL_SERVER_ERRORS);<br />
	oXmlHttp.setTimeouts(30000, 30000, 30000, 90000);<br />
	<br />
	//send the request<br />
	oXmlHttp.send(domReq);  // Get error here<br />
<br />

I found a workaround...
I replaced Msxml2.ServerXMLHTTP.4.0 with Msxml2.XMLHTTP.4.0.
(and got rid of the calls to setOption() and setTimeouts because they
are not supported by Msxml2.XMLHTTP.4.0)

Thanks for all your help anyway,

Debugging IE Addon

Hi,

If I am writing a toolbar application for IE using VS.NET, how do I debug my application?

If I set the Project properties' Start Application value to C:\Program Files\Internet Explorer\iexplore.exe, it is a release version and hence I can't debug.

How can I launch IE from my project and still debug it?

-Thanks in advance

hi Christian,

Actually this question was asked to me in an interview.He said their are four components and he claims that any one who does web services should know it.He just reveiled one that is SOAP and I am intreatsed to know about the other three and and want to learn about all the four components.

Offhad, I guess if SOAP is one, he's talking about the different protocols involved. SOAP is XML over HTTP, basically. I reckon a google would give you more accurate technical terminology than I could offer.
