There can be many reason, one of them can be you have not updated your web reference after making the change. if you can show me a bit of code I can try thinking more Smile | :)

The code above looks fine to me. did you try updating your webservice. If your webservice is in a different solution try following:

1. In your main project right click on the webservice and click on update web reference.
2. In your Internet browser type in the webreference and see what come up.

Cheers.

Reason to return binary file in XMLHTTP

Once i had the same problem that you do now
I believe that you can not have parameterized contructors in a class if you want to use them from client side
As i told you, when i tried to do that long time ago, it was .NET 2005 and i wasnt even able to add the web reference from the client (VB.NET 2005), cause i was getting the error that no parameterized contructor could be used

If the class that has the parameterized contructor wont be accesed from client side, then, there is no problem

I have this weird problem.

Scenario: When I call a page (using XMLHTTP) and write the page info to a file and use that file as an attachment to send along with an email.

Problem Child: The problem is that I always get the html file in binary form therefore I need to convert it to string before writing.

Question: Why does it XMLHTTP return in binary form? (I use xmlHttp.responseText and NOT xmlHttp.responseBody)

Funniest part: I get the other file content in the normal form and it looks fine. (I use the same function to build the files)

My biggest problem is that the application is in Classical ASP otherwise if it was in .Net, I could have used htmltext = StrConv(conn.responseBody, vbUnicode) to just convert the binary to unicode).

Note: Having xmlHttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded" doesnt help either.

Im glad if somebody can shed some light on this problem.... Why does XMLHTTP returns in binary form???????

Thanks

Hi,

I tried to install KnowledgebasePublisher 2.0 on Windows Server 2003 - Standard Edition. IIS 6.0 running on this server and there are some other web pages running perfectly. I installed PHP 5.2.3 and My SQL 5.0.4 which are the requirements for KnowledgebasePublisher. Those are seems to running perfectly.

But when I load the home page of the KnowledgebasePublisher, it is empty. No errors.

How can I fix this? I'm not very good with web development technologies. So step by step help would be really helpful to me.

Thanx.

You can use Web service by cread Webservice (If you dont have any webservise in your locahost)

Then in your project you must add WebReferen, choise Brown to your Webservice to this project; You can cornect to difirent server and use server's Webservise for using;

<br />
//Using Webservice as using Class; <br />
(WebService web = new WebService();<br />
        Label1.Text=web.HelloWorld()//----> this is a function you get from WebService;)

Please test again and reply if can't

Really easy
Make a Web service with a method that accepts a dataset and any other parameter that you need like client id...
The dataset should contain the whole datatabase or any info you need (i hope you are not trying to send to many records)
Once you have the dataset in the server side, you can just save those changes in the database in the server as you would with any other dataset
Im asumming you know how to make a webservice and i hope you do Smile | :)

Handling multiple sessions in an application

In my application I have a admin control panel where I can see the list of all the companies registerd with our system. We need to provide the option to login to any company from admin panel of the application. But at the same time I need to maintain a new session for each company i login to. For example If I login to company1 and i set the value of a session variable =1 and then i login to company2 and i set the value of a session variable = 2 then both of these values should be available in their respective sessions.

Please help me out!

Thanks in advance.

Sessions are kept automatically for each client connected, you only need to set a variable like session("VarName")=1
If someone else connects a new session willl be started

How to set the value of a hidden control??

Brendan Vogt18-Jun-07 23:51

18-Jun-07 23:51

Hi,

I need to set the value of my hidden control. Up to this point I had just played around, have not created the full value of the hidden control. I just want to add the current local date, but that I will do. I just need to know how to set the value parameter from a value returned from a function.

My hidden control:

<input
id="hdnLocalDate"
type="hidden"
value="javascript:GetDateTime();"
runat="server" />

My javascript function:

<script type="text/javascript">

function GetDateTime()
{
var date = new Date();

// Year
var year = date.getFullYear();
// Month
var month = date.getMonth();

}
</script>

Please can someone help me?

Regards
ma se

I want to set the value of the hidden control. When I do the following:

Response.Write("hdnLocalDate = " + hdnLocalDate.Value);

I get the value to be something like GetDateTime().

regards

badgrs19-Jun-07 0:08

19-Jun-07 0:08

simply add a return statement to your function, that should work no?

<script type="text/javascript">

   function GetDateTime()
   {
      var date = new Date();

      return date.toString("DD/MM/YYYY"); // you can use different date formats here
   }
</script>

Brendan Vogt19-Jun-07 1:01

19-Jun-07 1:01

When I do a Response.Write on the hidden controls value like:

Response.Write("hdnLocalDate = " + hdnLocalDate.Value);

..then it displays:

hdnLocalDate = javascript:GetDateTime();

What now?? If I do a view code, must it display the value property's value as the date returned?

badgrs19-Jun-07 1:43

19-Jun-07 1:43

Hmm, good point, of course the value field will never run the javascript, just take it as a string literal....how silly of me Sniff | :^)

You'd have to run some function when the page loads to populate the hidden field.

<br />
window.onload = function() {<br />
  hdnLocalDate.value = new Date().toString("DD/MM/YYYY");<br />
}<br />

Of course with runat="server" on the hidden form field its ID could easily change if its inside an INamingContainer.

Brendan Vogt19-Jun-07 2:21

Does onload exist?? I typed in window. and then there was no onload option. I am using VS 2005.

It's still not working:

<script type="text/javascript">



</script>

<input
id="hdnLocalDate"
type="hidden"
runat="server" />

Javascript intellisense in practically non-existent in visual studio, personally I use Aptana for all my JS/CSS development.

My fault again that it doesn't work, using ID.attribute won't work you need a reference to the DOM element via getElementById. Try this:

<script type="text/javascript"><br />
<br />
   <!-- // Hide from old browsers<br />
   window.onload = function()<br />
   {<br />
      document.getElementById('<%= hdnLocalDate.ClientID %>').value = new Date().toString("DD/MM/YYYY");<br />
   }<br />
   //--><br />
<br />
</script>
