I very like JScrip.NET with Class-based Objects function. It looks like clearly. Now JScrip.NET 's syntax has became close to with other OPP languages as C#, VB.NET. I want to translate some old JavaScrip functions to JScrip.NET.
But I don't now that what does JScrip.NET require about client web browsers. If these requirements are too high, may be I will have to consider again.
Please help me.
Thank you

JScript.NET is NOT a replacement for JScript. JScript.NET - for one - is a compiled, type-safe language. Also, JScript is an automation language, which uses dispatch interfaces to attach to late-bound functions and classes.
If you like having classes, you can create these even in JScript by declaring a function, use the this property, and define methods. You don't to use the .NET BCL like you do in JScript.NET, but I gave you just a couple reasons why this isn't feasible or possible above.
For more information about how to create JScript classes with properties and methods, see http://caucuscare.com/~roth/JAVASCRIPT/ch07_05.htm[^] (randomly pulled from google after checking its validity).

I guess this is a simple problem for which I do not have an answer. The following is taken from "global.asa" for an ASP application. It simply calls a method that parses an XML file (LoadSiteConfig). This method is included in loadsiteconfig.vb. However, it appears that the method LoadSiteConfig is not called on application start. I'm suspecting there's some syntax error the way I included the source "loadsiteconfig.vb" using the "src" attribute:
<script language="vbscript" runat="server" src="loadsiteconfig.vb">
sub Application_OnStart
LoadSiteConfig()
end sub
sub Application_OnEnd
end sub
</script>
Here's what "loadsiteconfig.vb" looks like:
Function LoadSiteConfig()
... parses an XML file using Server.CreateObject("microsoft.XMLDOM") ...
End Function
Am I doing the right thing? The way I included the ".vb" file in "global.asa"?? I'm having some trouble to trace where it went wrong that the function is not called it appears. Thanks!

Doesn't a Function have to return a value in VBScript? I don't use them often enough to be sure, but I seem to recall that functions have to be used on the right side of an assignment operator, while Subs can be called as freestanding entities. Try changing the Function to a Sub in loadsiteconfig.vb and see if that helps.

does anyone know how to use the Javascript fireEvent method? - I'm having some problems implementing it with an object in IE 6.
- here's an example of what does work.
<script>document.onkeydown = doalert<br />
function doCalc(){<br />
var evtObj = document.createEventObject();<br />
<br />
evtObj.ctrlKey = true;<br />
evtObj.keyCode = 70;<br />
<br />
document.fireEvent("onkeydown",evtObj);<br />
}<br />
function doalert(){<br />
document.forms.temp.field1.innerHTML = document.forms.temp.field1.innerHTML +String.fromCharCode(window.event.keyCode)<br />
}<br />
</script><br />
</component><br />
<form name="temp"><br />
<textarea name="field1">hello</textarea><br />
</form>
I am using microsofts dhtml editor in IE 6 and I'm trying to emulate the "tab" key in tables - so that it moves to the next cell... - one way of doing this is by replacing the "tab" key click with the "ctrl" + "down arrow" keys, now for some reason I cannot get IE to apply these keystrokes to the object and for that matter I cannot get it to recognize that the "ctrlKey" value is set to true (for a case where I would like to press "ctrl" + "f"...)
if someone can please help me out that would be greatly appreciated.
Thank you,

Does anyone know if it's possible to do *anything* other than a standard form post with a file input field? I'd ideally like to base64 encode the file data into an xml file and send the xml file off to the server, rather than using the standard multipart/form-data method.

 For the pro's I am sure this is simple:
I need to be able to filter my main table based on the contents using 1 of 4 fields in the table. It would be something like this, you have a dropdown box listing the type of filter you want, Owner/Phase/Type/Class; by selecting one of these you would then populate another dropdown box with all of those objects. Then by selecting your object from the second box and hitting a submit button you are then returned a filtered table of the corresponding objects.
I have been looking at the <a href="http://www.codeproject.com/jscript/dynaframe.asp">dynaframe</a> example posted here on the site, but can not get it to function in my architecture.

consider a FORM with a Browse for file feature, and some other FORM elements in it. Now, lets assume that some FORM processing can't be done in Javascript and needs to post the information to the server for validation. Now, if the validation failed, I would like to present the user with an option to resubmit a correction. This is where I am stuck.
The free ASPSimpleUpload component doesn't let me use FOR EACH element IN... which was intended to write out all the form data (regardless of what form elements I have) to a HIDDEN INPUT field. What I wanted to achieve by this is let the user correct only the non-valid fields, and the rest remain hidden. Then, upon re-submit, the form gets processed again.
1. What happens to the uploaded file? does it get uploaded again?
2. How can I go around the FOR EACH statment and let the user enter a correction? Is there a way to do a BACK button without loosing information?
Notes:
-I can't install DLLs or components on the server.
-The server only supports ASPSimpleUpload
-splitting the form from the file upload is hazardous, since someone can
start the form, enter a record in the database, and not upload files...
Appreciate the help or any input on this matter.
I have read all the articles regarding this issue on codeproject.
Thanks in advance!
Does ASP stand for Awful Server Punishment ?

Thats why real programmers use PHP
jk.
What happens to the uploaded file? does it get uploaded again?
AFAIK yes it would, if it was successfully uploaded in the first place, unless ASPSimpleUpload checks for duplicates and auto-renames files to avoid conflict.
How can I go around the FOR EACH statment and let the user enter a correction? Is there a way to do a BACK button without loosing information?
Have you considered using cookies? My experience is very limited in ASP becuz I switched to PHP very early, so I'm not sure why you can't FOR EACH elements while using ASPSimpleupload. How are you suppose to validate INPUT fields period? Anyways, you could store the info in cookies and just use JScript to restore values in INPUT fields when someone clicks back.
p.s-You might want to try and flag down Paul, he seems to be the resident ASP guru on CP
Cheers and remember, you could easily solve this problem with PHP

Well you can't FOR EACH elements because the object doesn't support this property. You validate input by using the upload_component.Form methods. But I need to write about 30 lines of code to extract all data instead of using a simple FOR EACH loop...
PHP is not an option since most of the code has been already written in ASP. converting the whole logic to PHP is a time hassle.
Appreciate any ideas!
Thanks.

Hi all,
I'm kind of a newby in webservices so I think this will be a simple question for you all.
I want to create an object on de webservice side (server) and return it to the application (client). The object on the client side must have the methods of the original object.
The code on the client side:
[webmethod]
public car createCar (string licenceplate)
{
car car = new car(licencePlate);
return car;
}
method in object class file (car.cs)
public string getLicencePlate
{
return this.licencePlate;
}
on the client side i want to ask the object its licenceplate. So: car.getLicencePlate();
But i can't see the methods. I only get the public attributes (and i don't want those)
Does anyone have a clear sample of returning Custom Type objects with WebServices or maybe give me a lesson in Serializable.
Ow.. I forgot... the client side is reacting asyn.
I hope someone can help me.
Kind regards,
Joost Voskuil

First, the method attributed with WebMethodAttribute must be on the server-side. You use the WSDL (contract) for the WebService to create a proxy object (i.e., an object that the client uses to proxy calls to the WebService).
As far as serialization goes, there is an example in your .NET Framework SDK. See <SDK>v1.0\Samples\Technologies\Serialization. You should also take a look at the System.Xml.Serialization. Many of the classes and methods in that namespace have example source code. It's just another way to control serialization that's designed more for XML. Just attributed classes and properties with various XML serialization attributes and have a public default constructor (a public constructor with no parameters).
Ultimately, serialization will get you farther (like with remoting), but I thought I'd mention XML serialization as an alternative when using WebServices (also handy to persist application settings and documents that you want other applications to be able to read easily).
Whichever way, just create an class that is attributed with SerializableAttribute (and optionally implements ISerializable, or that uses the attributes in System.Xml.Serialization. Pass that type as a parameter (or as a return value) in your WebService method and that's really all you need to do.

Thanx Heath,
What you mention helped me allot. Still figuring out the stuff, though. I have the system working now, but I’m certainly that it is al real quick and dirty solution. Do you have a clear example how you work?
Thanx in advanced

I don't, no, but there's plenty of examples here on CP and that you can find via google. Really, though, it's not difficult - just create an object that is serializable (or uses the attributes in the System.Xml.Serialization namespace and use that as your param or return type.

I am developing a web application that will be viewed with Microsoft Internet Explorer 6 on a machine with touch screen. The touch screen is the only input/output device. There is no mouse or keyboard available for the end user. (Imagine an electronic information kiosk.)
Here's my current problem:
I am populating a table that contains square, "button-like" cells with information from a database. The buttons are styled using a CSS Style Sheet.
I need the entire square cell to be hyperlink sensitive to accomodate for the inaccuracies of a touch screen. Centered vertically and horizontally in the button should be a link text. Currently, my solution allows for everything but centering the text vertically.
I am using the following class to style a block hyperlink of size 75px by 75px:
A.selectCategoryButton {
display: block;
width: 75px;
height: 75px;
vertical-align: middle;
text-align: center;
text-decoration: none;
font-family: Verdana;
font-size: 12px;
color: white;
border: 1px solid black;
background-color: #0074E8;
}
An example of one cell in my table looks something like this:
<table>
<tr>
<td>
<a href="somelink" class="selectCategoryButton">
Link Text
</a>
</td>
</tr>
</table>
The result rendered in a browser is a 75px by 75px cell that is entirely "click-able" with all the properties defined in my class, BUT the text appears at the top of the button like this:
___________
| Link Text |
| |
| |
| |
|_________|
I think this has to do with the fact that the CSS vertical-align property can only be used with in-line objects and not block objects.
Any workarounds or other solutions? Feedback is greatly appreciated... This is a somewhat time sensitive project.

I haven't tried it, so this is no more than a swag, but is it possible to place the text within <P> tags and define the box characteristics (margins, padding, etc) for the P element to constrain the text to the center of the cell containing it?

Use padding to achieve what you want.

It's been awhile since I pressed the panic button. But I'm have trouble connecting to my SQL server from my classical ASP application. Here's the error:
Microsoft OLE DB Provider for SQL Server error '80004005'
Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection.
/SomeDevFolder/login.asp, line 69
If you print the connection string to screen:
"Connection string: Provider=sqloledb; Data Source='XXX.XXX.XXX.XXX'; Initial Catalog='MyDatabase'; User ID='sa'; Password='secret'"
1. I want to emphasize that the ASP script works fine with one SQL server and not with another.
2. The SQL server I'm having trouble to connect to is the default instance.
3. Yes, I have checked and double checked: The SQL server is in "Mixed Mode" (authentication) - I have no idea what it has to do with trusted connection or not. I have supplied both username/password. What more do they want from me?
4. I used Query Analyzer to connect to the SQL server I'm having trouble with - using same connection string (user name and password) - it worked fine.
I doubt if it's has to do with my ASP code since connection to another server works, but, here's the code anyway:
oConn.ConnectionString = "Provider=sqloledb; Data Source='" & Application.Contents("sDbSource") & "'; Initial Catalog='" & Application.Contents("sDbInitialCatalog") & "'; User ID='" & Application.Contents("sDbUser") & "'; Password='" & Application.Contents("sDbPassword") & "'"
oConn.Open
Help!

Have you verified that your error isn't related to a permission problem at the IIS level (rather than the SQLServer level)?
It sounds like your request isn't making it to the database.
