how to pass the value from comboBox component to asp.net in flash

Hi! Need help here... Just wondering how can I create multiple drop down lists that will email the chosen values to certain people/s.

Ex:

Web browser:

[dropdown 1 value][dropdown 2 val][dropdown 3 val][dropdown 4 val] Send

then the email will look like this:

Sample Text

dropdown 1 value
dropdown 2 value
dropdown 3 value
dropdown 4 value

Sample Text

Pls help me... Thanks!

You can't, at least, not in any useful way as mailing from the browser is not really appropriate. It is possible with a mailto, but the results will be extremely ugly and a big dialog window will appear every time:

First:
Second:

A much better method would be to have an email script located on the server which is called whenever the 'send' is pressed.

Hi,

Is there a way to make cross domain webservice call from client code(javascript or xmlhttp)? Webservice is in intranet and not open to the outside world therefore i can't make a server proxy Frown | :(

Thanks,
Amit

Thanks,
Amit

The short answer is no. At least not to my knowledge.

When you make an XMLHTTPRequest call it is from a javascript. XMLHTTPRequest is limited to calls to the same domain for security reasons.

You could use the old iframe trick. You can load an iframe with anything the client has access to, have the iframe hidden, and access its contents via javascript. What we use to do before XMLHTTPRequest was ubiquitous but more work involved.

I have a console application with the following code:

Dim cmdScript As String = "c:\ourdlls\winzip\wzzip c:\temp\a.zip c:\temp\test.txt"  
Shell(cmdScript, AppWinStyle.Hide)

That works fine.

I also have a web application with the same above code. The problem is that although the wzzip command is invoked, it simply does not zip the file. Seems to be some permission problem. Out of desperation, even after giving the winzip and temp folders full control to everyone, it still doesn't work. I then tried by moving the test.txt file to the web application folder, even giving everyone (including the local ASPNET) full control to it as well, but alas, no go.

It appears that wzzip is using some system routine that it doesn't have authority to, but even if I run Filemon, I can't see any authority problems popping up.

I have rewritten the above code so that it uses a separate process and examined the StandardOutput:

Dim ShellProcess As New System.Diagnostics.Process
ShellProcess.StartInfo.FileName = "c:\ourdlls\winzip\WZZIP.EXE" 'test.bat
ShellProcess.StartInfo.Arguments = "c:\temp\a.zip c:\temp\test.txt"
ShellProcess.StartInfo.CreateNoWindow = True
ShellProcess.StartInfo.UseShellExecute = False
ShellProcess.StartInfo.RedirectStandardOutput = True

ShellProcess.Start()
Dim myStreamReader As StreamReader = ShellProcess.StandardOutput

Dim s As String
Do While myStreamReader.Peek <> -1
        s &= myStreamReader.ReadLine
Loop
ShellProcess.Close()

If the above code is run as a console application, wzzip writes a line to standard output indicating that the command was invoked and then another line indicating that it zipped the file. When executed from the web application, the standard output shows that wzzip is being invoked, but it doesn't display the line that it zipped the file, or any error either.

Does anyone know how to get wzzip to work from a web application?

What does it do ? Doesn't .NET 2.0 have zip support ?

You definately cannot interact with the file system above your web application root in .NET.

Christian, I don't know if .Net 2.0 has zip support. I haven't seen anything regarding that.

As for interacting with the file system outside of the web application, well, I do it all the time! I have web applications that access shared folders all over the place, including other servers.

Just use SharpZipLib[^]...

Yes, but can you blame them for doing so if that's the only legal way they can hire programmers they want at the rate they can afford?

SharpZip worked. Thanks Shog.

Thank you, PrakashBhaskar. I am looking into that now. I have been working with Winzip tech support trying to get their product to work from a web application in .Net to no avail. I have a problem believing it can't be done. They say that their program is registered on a user-to-user basis. The fact that we have a different user than ASPNET in the machine.config file may be related to that fact, but since they don't work with .net, they are clueless. So, maybe that software you suggest is the best way to go.

Hi I am building an application.in which I send a mail to a user..when user click on that link he is redirected to a html page..
Now what I want is when that particular html page loads it redirected the user to an another aspx page automatically based on the information present in querystring (link which user press).

Plz answer & help this novice programmer..

hiiiiii

So what is the exact problem you are facing?

I want the javascript code or methods which can be used to redirect to another page based on value of querystring..when the page loads.

hiiiiii

you can use this code

window.showModalDialog("abc.aspx?qs1=" + qs1_value + "&qs2=" + qs2_value);

.... //or

window.open("abc.aspx?qs1=" + qs1_value + "&qs2=" + qs2_value);

....//or

window.location.href = "abc.aspx?qs1=" + qs1_value + "&qs2=" + qs2_value;

and.. how can I access particular value from my querystring????
link is like "http://www.abc.com?pageno=8&id=2"
& "http://www.abc.com?pageno=7&id=2"

I have to access pageno. from this querystring & have to redirect to two different pages based on page no.s?????

hiiiiii

suppose your link is

"http://www.abc.com?pageno=8&id=2"& "http://www.abc.com?pageno=7&id=2"

then code behind page you can use ...

string page_no = Request.QueryString["pageno"];

sorry my mistake...
this is a html page..

hiiiiii

sorry my mistake...
this is a html page..not an aspx page...

hiiiiii

then you need to use javascript code for that...

this.page_no = "<%=Request["pageno"]%>";

..

How exactly will that work for a static HTML page? Why don't you google it
