Yes, theoretically the correct answer exists, but in the Javascript it doesn't.

hi...
Does anybody know if there`s a limit to the form post method?
I`m trying to pass some values (form input hidden/text and select fields) through ASPX pages, but my Request.Form collection isn`t complete on the receiving page - it only has the firsts elements in my form. The page that passes the values is only a html page with the .aspx extension - it doesn`t contain anything ASPX related.
I`m using .NET 2.0 with VS2005 and IE6 and FF 2.0.
Also, i have read some hints on the internet without any help (changing the reg. [B]MaxClientRequestBuffer [/B]value or putting the ENCTYPE="multipart/form-data" into the sending form tag)
thanks in advance...

You set up the website in iis? I would guess that some of the properties in IIS for the site are wrong. You are trying to access the site through a url correct? If you try to just double click on the default.aspx file it won't automatically open in a browser.

correct on all counts

So if you go into IIS and go to the web site you set up. In that directory in iis if you right click on your default.aspx file what happens? Another question is are you missing some files. Like is the bin directory with all the dll's in the site?

I am trying to implement an ActiveX control given to me by a hardware developer for their equipment. I am new to Java/XML and really can't figure out the correct function/syntax to get this working. This is a snip of the VB code that gets the readings from the ActiveX control called "Temp":
<br />
rval = Temp.GetReadings(sngTemperature, lngTemperatureError, sngTemperature2, lngTemperature2Error, sngDewpoint, lngDewpointError)<br />
if rval = 0 Then<br />
data = sngTemperature<br />
I need the "data" value. If I change the code to "data = sngTemperature2" then I get a different value from the control. I'm not having much luck with this so any help or advice would be appreciated!
Thanks much!!

Thanks for the reply.
I know this is a difficult problem, and there is probably no 100% secure solution. But, it is very bad practise to rely on confusion to secure something like this. Seems like thats the only way though.

Well, it is not necessaryly a bad practice. For instance if you are familar with serialization. It is pretty easy to serialize an object (class) and pass that in as a parameter. If you happen to have lots of parameters to pass that would be a good idea. If you know your web method depends on an object being passed back and forth it makes your custom web service pretty custom. Could someone figure out the class you are passing back and forth, maybe, but it might be more work then it is worth. Sometimes that is what you have to do. Make it more work then someone is willing to go through. If you didn't want to pass a serialized class as the parameter you can easily pass a dataset. So you could have one table with one row and the row would have the columns that would match to the parameters for that webmethod call. A little less work, but a little easier for you if you are not as familar with serialization.
Hope that helps.

I have a update panel on my page.
There is a asp:button in my panel.
On the click of that button, I want to register a StartupScript for the page. So as when the page renders again, that script gets executed.
But I am not able to execute the startupscript on partial page rendering.
the same works fine if the button is out of update panel.
I think this is because, during partial page rendering Load of body is not being called. and so, the script is not getting executed.
Please suggest the way to register such startupscript for the AJAX enabled page.
Thank you,

Hi All,
I have developed an FTP client. When I try to download some of the files I get the error "dst_dataconn ended unexpectedly" with error code 550. Does any one know why this error pops.

That is the access denied error code. You may have a problem...

Thank you.
I was able to solve that problem. My socket was time based(timeout) and not databased. I had to make some correction in the code so that it recevies the data till the last byte.

Hi.
I have a webservice - and I want to make sure that only MY application is using it.
Is this possible, in a secure way?
Thanks,
Cormac

It helps if your webservice isn't exposed at all. That means get rid of all disco file on your web server.
In your web.config you can add this code:
<webServices>
<protocols>
<remove name="HttpPost" />
<remove name="HttpGet" />
</protocols>
</webServices>
That causes your webservice to only allow soap protocols. This means if you access your asmx file you would see links you can click.
Finally, you could have your application pass some sort of key into each request. Of course, if you don't use ssl the data could always be read. I think if you webservice isn't exposed through disco files and it rejects http protocol you probably have 90%. To go the whole way you would have to have ssl and some sort of key.
Hope that helps.

That's a good idea, I never thought of removing the WSDL!
I am already using a username/password type of authentication, which I made myself, and it will be operating over SSL also.
But, I am worried that there is a possiblity of my users creating their OWN application, and utilising the web service (with their own credentials), which would not implement the logic based in my client application, and therefore wreak havoc.
"To go the whole way you would have to have ssl and some sort of key."
Even then, hard coding a key into a .NET app is really dodgy - too easy to decompile.
Maybe I'm being too cautious?
Regards,
Cormac Redmond

When I am talking about a key I am talking about using a private key for signing. If you are already planning on using a username and password along with ssl I think all you need to do is remove the ability of non users to see your webservice.
Ben

Yes, but there is still the risk of a registered user creating their own application.

If you are really that concerned about this, you could pass a custom xml structure. That way if the correct xml structure is not passed in the webmethod won't work. This adds a level of complexity that you may not want to deal with.

What would that do that a tech-savy user couldn't?
|
|
|
|
|
Well, if normally you just have web methods where you pass in things like username, password, orderitem, quantity etc. That is pretty ovious. If you have one parameter called param1 which has to be xml that contains all the parameters for that method. That would be a bit harder to figure out from anything you could get from disco file or anything else.

I'm confused. Doesn't SOAP just wrap itself in HTTP? If POST and GET are blocked, how is SOAP not? What is the difference in the headers?
P.s., I just tried it, and it blocked my SOAP requests (which I expected). Can you explain what you meant?
Thanks,
Cormac

YOu can try this instead:
To leave WSDL file generation on for Web services within a Web application, but not provide any human readable information regarding the Web services, you can add an <wsdlHelpGenerator> element to the Web.config file for the Web application and set the href attribute to a blank HTML page you have created. The following code example is an excerpt of a Web.config file that sets the service help page to a MyBlank.htm file in the docs folder beneath the folder containing the Web.config file.
<webServices>
<wsdlHelpGenerator href="docs/MyBlank.htm"/>
</webServices>
