VS 2010 - Saving And Retrieving Image
Nov 16, 2011
I have a very simple app here. It pulls a users picture from AD, saves it and then displays it as an asp:Image. The program runs perfectly in the IDE but fails after I publish it and try to browse to it. Here's the code and the error.
Default.aspx code.
Code:
<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"
CodeBehind="Default.aspx.vb" Inherits="WebApplication3._Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<asp:TextBox ID="TextBox1" runat="server" Width="247px"></asp:TextBox>
[Code]....

I have encountered the task of saving an image to a MsSQL Server Database. (Although I haven't even managed to do it yet).
But anyways I need to link this image from the MsSQL Database to Gridview. Can this be done ?

I'd like to know how to do it myself. Surely you can grab something from the html or something?

I am reviewing some web code and I am not exactly sure how ASP.net session state works. If a User object is saved to the session state during login, and User.FirstName and User.LastName is set. If other web pages retrieve the user object from the session and set the FirstName to something else is that persisted on other web pages? Or, do you need to re-add the user object back to the session once it has been modified?

I am facing a problem with retrieving an image and showing it on asp.net grid. I migrated MS Access database to sql server. Image are visible in Crystal report when fetched from the same database (migrated sql server database). But same images are not visible in ASP.Net grid view or simple asp.net image control. Following is my code
SqlConnection oConn =
new
SqlConnection(ConfigurationManager.ConnectionStrings["csr"].ToString());
oConn.Open();
SqlCommand oraCmd = oConn.CreateCommand();
oraCmd.CommandText = "select top 1 photo from [test] where photo is not null";
SqlDataReader dr =
null;
dr = oraCmd .ExecuteReader ();
if(dr.Read ())
if (dr["photo"] !=
null)
{
Response.ContentType = "image/gif";
Response.BinaryWrite((byte[])dr["photo"]);
}
This function is getting called from another page . "hlopen" is hyper link in the grid. hlopen.NavigateUrl = "GetPhoto.aspx?id=1";

We have a scenario where we would like to allow our users to upload images to the site. We are running on ASP.Net. A quick search did not result in anything good. It would be great if the control is free/open source but we do not mind paying a little bit.

I have an application called barcode available on a server on the web. The application is used to generate barcodes. The user is able to save her progress directly on her desktop, however though whenever the user try to load the saved progress. It is doesnt remotely connect to the server, instead, it defaults only the saved copy on her desktop. so for example
we have the following aspx created
barcoded.aspx. The barcoded.aspx is available on the server. the page has the following information
Name: PRT321-1 Code: 456789-1000
Label: 678900-001-001
Now, this information is saved as webpage.html. however though, when the user goes to the saved location and clicks on the saved copy, it automatically load the copy as a webpage and allow the user continue with the modification online but that is not the case. Does anyone know how to fix this problem.

What is the most correct way to save your connection string when using the n-tier approach ? Right now I have two windows app and one web app using my DLL library, what I'm currently doing is to create a static
method inside my dal "GLOBALDAL"
inside I'm making this check:
Code:
if (System.Web.HttpContext.Current != null) ...
if httpContext.Current is null
That's mean that one of my windows applications doing the request, if so I get the CN from a file otherwise it's mean its the website knocking on my door so I get the CN from:
Code: System.Web.HttpContext.Current.Application["ConnectionString"]
I am thinking of changing it all and just set properly in my DA layer that expose the CN as a string. But I fear of security issues. So what is the correct way?

I have used login control in web app project and I am trying to retrieve several messages after clicking login button according IsApproved property in aspnet database, aspnetdb_Membership table because no user can be able to login without activate his account by getting activation code from his e-mail.
so when IsApproved = false for any new user (without activate)error message after clicking login button it should be (Sorry your account dose not activate after registration) or so on but if any user insert wrong user name or password he should get (user name or password not correct) after activation IsApproved = true the user can login

I'm adding <ASP:TextBox>'s to a page in code.I'm going to set their ID and stuff like that.I'm wanting to retrieve the text of those textboxes on a button press.Now I know I can't simply do "Me.MyTBName1.Text". I guess I could loop through the controls and compare IDs. I'd rather be able to get the textbox's text directly somehow though.I could use Javascript to get the value, but I don't think I can use it server-side at that point.

I am retrieving a word 2010 document that has been uploaded to a sql 2005 database. When I subsequently download and open the document in a word window it states the file is corrupted and gives the user the option of repairing the file for display. This always works fine but the corrupted message is always presented for all DOCX files. The DOC files from an older Word version work fine without incident. the section of code, VB.NET, for streaming the document out to display in Word is:
Dim bytes() AsByte = CType(dt.Rows(0).Item(2), Byte
())
Response.Buffer = True
Response.Charset =
""Response.Cache.SetCacheability(
[Code] ....
Where the content type value, in this case, is "application/vnd.openxmlformats-officedocument.wordprocessingml.document" (rather than "application/vnd.ms-word").
The filename is simply the full name of the document and the data itself is loaded into the Bytes var. I got some time back... it just doesn't like the new and improved word 2010 files.

I would like to be able to read an image based on a url hosted elsewhere. To be clear, this is a legitimate service that is provided and they do allow caching of data, so I'm not trying to steal someone elses data.
So far I have the following code:
public static byte[] GetBytesFromUrl(string url)
{
byte[] bytes;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
WebResponse resp = req.GetResponse();
The area that I'm looking to improve on is the emboldened line. I think it would be better to read in say 1024k chunks until the file end. Can anyone help me out with the syntax for this?

I tried doing a search about saving a gridview as an image but have not found anything that works. I need to capture it or create one as an image to send to a mobile device for a dashboard. I know people tried capturing the grid like a screen shot but is there any other way? Sometimes the grid goes off screen. I assume i could create an image dynamically right? The tough part is setting the width of the columns and right/left justifying the data. Even if I could save an html table to an image also that would work.
