Sending ByteArray Image To Server Side And Save It To Local System?
Aug 19, 2009
I want to send a image to server side using HTTPService,I am using ASP.NET for server side coding. I don't know how to write server side code to receive the image sent as a byteArray, and I am also not sure if my client side code is correct or not。is there any IT PRO..[code]I could not get the image in my disk,I think the flex side should have not problem, but the VB code side should be something wrong.

I'm having issues with the way I've been reading my image datatype blobs from my SQL database (code below). This code works fine when I access this page directly. The PDF will open and works just fine. However, when I try to use this page to download a file and save it to the file-system programmatically, it fails (500 server error) and I've verified that it's the same URL either way.So, my question is what is the best way to download a file from a database image datatype and save it to disk?PDF.aspx

<%@ Import Namespace="System.Collections.Generic" %>
<script runat="server">

I'm trying to load an image that is in the root dir of my project:
Dim b As Bitmap = New Bitmap("img.bmp")
but it doesn't seem to find the file.
I've tried various combinations like ~img.gif, /img.gif, img.gif, ~/img.gif etc, but none seems to work. How to access the "current directory on server" in ASP.NET?

I am transmitting data over an IP socket and receiving the data via a second program I have written. The server was in VB6 and am now creating a new one in vb.net to run as a service. The major issue I am having is related to the encoding features.
Issue 1 to be able to correctly encode a bytearray so that when it is received by a VB6 program via winsock that the data will be in the proper ANSI format for the pc to read it correctly. So far this works on some files and not on others depending on the content of the file.
Issue 2 to be able to correctly encode a bytearray, send it to a vb.net host program and correctly [decode?] write it to disk.
To make things a little more complicated I must also be able to do this where the client resides on a Windows Mobile, Windows CE, or Windows PC. I have been running some tests and have gotten mixed results.

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.

I have developed an ASP.Net 2.0 application and I am facing problem in sending email from my Web Server. Following is the VB code I have used to send email from my web application. Thing is when I try to send email from my local system (laptop) the email goes out fine and reaches the recipient address instantly but when I try to send email from my web server it fails.My hosting provider gave me a relay-host address for sending out email. The email goes out fine but the relay host has an annoying amount of delay in email delivery which is a problem during the sign up process.
Here is the code I am using:I have imported system.net.mail in my code and used async="true" on the aspx page.
Private Sub SendMail(ByVal actcd As String)
Dim mailMessage As New System.Net.Mail.MailMessage
mailMessage.From = New MailAddress(support@ihomejobs.com)
[code]....
I have tried the above settings and they work fine from outlook and the application when tried on my laptop but these settings fail on web server.I want to send email from my web server without using a relay-host.

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 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 a SQL Server database with a table that has a column that stores an image. I have another database and I would like to store the image from the SQL Server database into it. It's type is MS Access 2000 format .mdb.
The problem is I get back the content of the column and I put them in an array of bytes as follows:
Dim arrByte() As Byte = CType(dtAll.Rows(0)("DailyProgram_Image"), Byte())
It sends me back the data of the image as byte type. When I try to save this into the access DB it give me an error because of type mismatch.

My boss wants me to create local databases on the light-side of things. I was researching on what solutions are available, we discussed the possibility of using text or xml files... but we dropped the idea since we want to use SELECT, UPDATE, DELETE command sets (or the like)I proposed the idea of using Access files (mdb) but he told me that he doesn't want the user to have Access installed on their computers.What are the choices avaible, am I forced to install Access on machines that would be using my VB .NET app to access mdb files?

I am currently trying to create a DLL for use with a RESTful api. The only issue I have is that so that this DLL can be used in a service or a program without a GUI, so I can't use "Imports System.Drawing.Imaging" as this requires a form. I have looked around for examples to handle this without using this library but have had no luck.

I have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.
This works fine when I give the location of the image (the full path ) on my computer - but then of course it will not work if I use the solution on a different computer .
So I have made a folder named "Pics" inside my application and added two images into it.
How do I get to this local folder in the following code?
Picturebox1.image = system.drawing.image.fromfile (??? )
instead of the usual,
Picturebox1.image = system.drawing.image.fromfile ("C:UsersMyName My PicturesMyPicture.jpg" )
