We have a Try/Catch block of code in our web application to trap a certain exception. What we want to do with this exception depends on the current time. If it is between 4:30PM and 3:00AM we will want to send an email, otherwise we will throw the exception.
Try

Catch ex as WebException

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 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.

Can I send an object from client-side javascript to server-side code via ASP.NET ?
View 5 RepliesI 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]

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?

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()));
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 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.
View 14 RepliesI am starting a butterfly program and having an issue and really just barely have it started and would like to get some helpfeedback on how to do this. The following is the instructions and I will make a second post on what code I have so far...The butterfly is going to be moving from side to side in a slightly upward assent when the animation starts. You need to build a set of controls that allow the user to control whether the butterfly ascends (up) or descends (down) and also allows the direction of the butterfly to change (left or right). The best way to implement this feature is through the use of keystrokes that when pressed act to control the direction of the butterfly. Whether you implement this feature through keystrokes or controls, make sure that the feature is communicated to the user.
Butterflies fly by opening and closing their wings. So it is expected that the butterfly will alternate between opened and closed as it wings its way across the form. If the butterfly is moving right, make certain the butterfly graphic displayed shows the butterfly as moving toward the right. If the butterfly is moving to the left, make certain the butterfly graphic displayed shows the butterfly as moving toward the left.
If the butterfly reaches the top of the form in its assent, it should wrap around to the bottom of the form. If the butterfly reaches the bottom of the form in its descent, it should wrap around to the top of the form. If the butterfly reaches the left edge of the form, it should begin flying toward the right side of the form. If the butterfly reaches the right edge of the form, it should begin flying toward the left side of the form. If the user changes the direction of the butterfly, insure that the correct graphics are used in relation to the direction of the butterfly and that the butterfly moves in the indicated direction. Please note that when the butterfly reaches the edge of the form, the butterfly must change direction regardless of any user input.
I have an ASP program that synchronizes 2 databases. I also have a VB.NET program compiled down to an EXE that fills the source database before the synch happens. In the back of my mind I know I should be able to link the VB & ASP .NET programs together since that's the power of .NET. Alternatively, if I could run the EXE from ASP it would be just as well for my project. I do have the source to both programs. The ASP script was written with a text editor - the VB was in VB 2008 Express.
assume I know nothing of linking assemblies and such because I don't - I just read that in an article. I'd prefer ASP but if necessary I could use the ASP.NET script to launch the EXE. The code is legacy ASP with VBScript so all our ASP.NET stuff is the VB flavor as well. C# makes my other programmer's head hurt so for his sake this will have to remain VB.
Is there a way I can relatively easily launch the EXE pre-sync program and have it run when the ASP synch script starts?

I was having problems inserting a string into the following tag : <tr id="rowBulkOptions" style='<%# sBulkOptionsRowStyle %>'> Don't ask why I'm using tables sBulkOptionsRowStyle is a Public string in the aspx.vb file. Seemingly the only way I can get this to render is to put Page.DataBind() in the Page_Load, Page_PreRender etc.. However this causes me problems because Page.DataBind() binds all controls on the page. I could use <%= BUT another part of the code inserts controls into the page and apparently you can't use <%= and insert controls.Is there a way I can just say 'look, put sBulkOptionsRowStyle into the page

I just tried to fill my dropdown in vb.net and I have the same result. The dropdown is full but when I do a postback I have no selected value Actually on the server side when I put a breakpoint on the dropdown, the item count is 0. I don't understand why... It's like the 8th dropdown list in this project and everything is the same but this one doesn't work.
I don't do any binding on the page load. it's all in the aspx file well it works ONLY when I add autopostback="true" SelectedIndexChanged="dd_ressource_composante_SelectedIndexChanged" for the dropdown.And theres no code in dd_ressource_composante_SelectedIndexChanged It's vb.net for the server side?
