VS 2005 Remoting With Server's Event Handling On Client Side?
Oct 26, 2009
Anyone has a quick and dirty sample coding to making this work? Currently, I have server, client with Interface object as intermediate object between the 2. If I declare events in the Interface, then Dim object on client side with "WithEvents", I'll get error when I reach this line:
vb
serverObj = CType(Activator.GetObject(GetType(InterfaceObj), szURI), GetType(InterfaceObj)
Having headaches looking for solutions.

Ultimately, what I want to accomplish is an AJAX-based messaging system. I already have a database table for messages, and an ASPX to add new messages (and declare old messages no longer relevant).
The current messaging system simply polls the server every 15 seconds, and re-pulls the current message set.
What I am looking to do is: On $(document).ready(), register an ajax callback function that listens for a server-side event (e.g., MessagesUpdated) On table insert/update, fire MessagesUpdated server-side.
This way, whenever the table is updated (or new records added), any clients listening know that new data is available and can re-poll the server then.
Ideally, I'd also like to make the new data available as an event argument (to minimize re-polling the db).
I can find references to something like this in other languages, but I cannot find any actual code examples to get me started.
Assuming this is possible to do via .Net, can anyone help get me started on this?
I'm using the 2.0 Framework. Also while I added a VB.Net tag, I can read C# reasonably well, so please feel free to post in either language.

I am struckup with a problem from last two days. I am creating a web application using VB.NET, Ajax & RAD Controls. When user clicks on a button I want to open a RAD Window and show the list of ledgers available to the user, so that he can select one from the list. And to open that window I have to call a java script function from client side, which is already achieved using the below code.

I am building an internal web page which retrieves binary data from a SQL database, converts the binary to an image file, then opens the file on the clients PC.In debug mode, this works fine, because the program downloads the file successfully into a temporary directory, converts it to the image then uses System.Diagnostics.Process.Start() to launch the image file in the associated image viewing program.However, as soon as I upload it to the server, two undesired things happen:
a. The file gets saved on the servers temporary directory, instead of the client temporary directory (I kind of expected this to happen, so this wasnt much of a suprise)
b. System.Diagnostics.Process.Start() does not launch the file successfully. Nothing actually happens when it gets to this part of code, however I suspect that it is trying to launch the process on the server end, instead of the client end.
how I can get System.Diagnostics.Process.Start() to launch on the client end OR how I could get the image to just appear in the clients web browser instead?

Can I send an object from client-side javascript to server-side code via ASP.NET ?

I know this defeats the purpose of client side vs. server side (refer to title of this thread). What I would love to do is build my own custom progress indicator on the client showing how far a server side code has progressed. I figure if I could only get a JavaScript to fire and render a value of some control at pre-defined intervals while the server is working I could make it happen - but alas I'm beginning to believe that this is impossible. Below is some code that performs three 2 sec loops. At the end of each I want to change the visible value of a control on the browser. [Code]

Using the following script:
$("#some_button").click(function() {
var changed = [];
[CODE]...
I need to send back the id, the old value from _1 and the new value from _0 back to the server. What is the best way to format this data so I can easily extract the data from the server side so I can easily email someone for example to let them know which textboxes have changed, what the old values were, and what the new values are
At the serverside level, I am using .NET-3.5 (VB). I know how to send the data bacl. and how to email the data, I just wanted to know how to best format the data at clientside before sending it back. I could have upto 50 sets of id, old, and new values to send back. Sorry for not making that clear earlier.
Example:
How can I modify the script above to generate this?

{
"id": "name_0",
"new": "text",

I'm trying to, from a client-side piece, call off to a server-side piece. I need to do this synchronously. On my server-side code, though, I'm calling off to another piece of code, which I want to have a maximum of, say, 10 seconds to return a value. If I don't have a response within 10 seconds, I want to force my own server piece to set my result equal to 0, and return to the client.
Here's what I have on my server-side code so far:
Public Function GetWebResult(ByVal inputParameter As Object) As WebReturnObject Implements IWebInterface.GetWebResult
Dim result As New WebReturnObject
Dim webItem As WebItem = Nothing
[CODE]...
I realize this code is not functional. The problem is that I'm unsure how I would go about getting back into GetWebResult to set the appropriate return values before it is sent back to the client.

I add an option to a select with jQuery. When I save with an asp button, I don't see the changes on the server side in the click event.
And the HTML is all correct after I add the option.
Is it a coding problem or I don't understand something?
$(selectCourant)
.append($("<option></option>")
.attr("value",$(dropdown).val())
.text($(dropdown + " option:selected").text()));

I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.

installed in a another system. For some quite time, the client system is sync with my system. I have updated its database, i also updated the clients executable files. I have never tough any references in the system.My question is, an error occurs occasionally which is "Object reference not set to an instance of an object". This error does not occur in my development environment but is displayed on the client's PC

I want both the client and server to write and read resp. at a constant rate (which can be configured on the GUI of the client) to the buffer.I am able to send from the client at 150 bytes per packet Now, I should be able to read also at 150 bytes per packet on the server too Since, both are connected through a socket, can we retrieve the socket params (set on the client size, like 150 here) from the server end, using the tcpServer object.Or is it must to send an initial setup packet which tells about these client params and so accordingly the server can continue?

I've got a bunch if labels that are changed as a user inputs data into a form of mine. The Labels are changes with js on the client side. I then after all the submission are in put use a vb script to pull the string values from these labels. The problem is the vb net part is not reading the new values of these labels. Anyway I can get it to read the new values? I have over 40 labels.

I'm setting up a basic TCP client/server system and I'm wondering how the back-and-forth communication should ideally work. In my specific situation, the client will have to submit login credentials, and make specific requests from the server (the server interacts with a remote database).Here is what I would THINK to do.. and I'm just looking from input from other devs.
SERVER: Wait for new connections
CLIENT: Connects to server
CLIENT: Once connected, send login credentials with an instruction code.
[code]....
And another scenario.. let's say the client wants to request a log of what's happened on the server recently (the text of a console application window).
CLIENT: Send request message to server for recent log
i.e. $REQ$,105
SERVER: If instruction = $REQ$ and request id = 105, get window text and send to client
i.e. $DATA$,105,<data here>
CLIENT: If instruction = $DATA$ and data id = 105, parse data and display to user
The data being requested could be plain text, or a .net datatable translated into XML, etc. It could be a variety of things.

The problem im having is that I have a table that when a user click on a button it adds a row to the table via javascript, which works fine. The problem is that if a user need to update other data the user click another button which refreshes the page and all rows the user created in the table are deleted. My question is what can I do to make the rows not to be deleted once the page is refreshed? I know some might think, just not refresh the page, but there is to much data that has to be displayed and a new query has to be generated to grab the data.

I have web page with four grid views. Each grid is hidden under a div tag. Whenever user clicks on div the data grid corresponding to the div is shown. I have binded data to the grid views at the page load only, since the data size is huge I cannot load the data binding at the page as the time taking to page load is huge. I was thinking a way that grid view gets data loaded only when user clicks on the corresponding div tag

I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false.
Example:
Page code -
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %>
[Code].....
I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the <div>, making it visible at initial page render, the control works as expected.
So, is this a bug within the AsynchUploadControl, or am I not grasping a fundamental concept (which happens regularly)?

Decimal type columns have Precision and Scale where the length of the integral part of the decimal would be Precision - Scale, if the Precision is 4 and the Scale is 2 then the integral part can only contain 2 digits (4-2). As such I will probably need a control that I could set how much it should accept on its integral part. In that regard I am not sure which control is best for such cases, I could try to make a usercontrol that will handle that but is there any other control out there that I could utilize for this purpose, intrinsic to .Net or a custom control out there? I could also just validate the data keyed-in but the above solution seem to be more user-friendly. Curiously, when databinding such Decimal type columns, how is it handled when the specified integral part exceeds the allowable size (Precision minus Scale)?

how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])

Try
SyncLock myclient.GetStream
