View 2 RepliesI have a routine to display an image on an aspx page. The url for the image uses imagerender.aspx . This is simply an empty page with code behind:
myClass mysub = new Myclass(); // create class
Stream strm = mysub.DisplayImage(UserID); // call method to load bytes from db
byte[] buffer = new byte[2048];
int byteSeq = strm.Read(buffer, 0, 2048);
while (byteSeq > 0)
{
Context.Response.OutputStream.Write(buffer, 0, byteSeq);
byteSeq = strm.Read(buffer, 0, 2048);
}
Ok, this work fine when testing on my local machine, but when I move it to the live server, it comes up with an empty image box!
It looks like there must be a problem with security, maybe with ISS.
Does anyone know what changes I can make to fix this problem or what setting to change in IIS 7?

I have an UpdateProgress control to activate on a postback of a button control. The button_click event is performing a Response.Redirect to show CSV Report. The report comes up and the UpdateProgress bar is spinning on the page with the button. However, once the user closes the report and control is returned to the page, the UpdateProgress image is still there spinning.
How can I use the UpdateProgress bar to finish and go away?

how to call the same page for fetching data using jquery
In the below mentioned ajax function, I would like the url to be the same page.
When the ajax call succeeds i want the image to be displayed in an img tag.
I have started learning ASP.net and SQL on and off the past month. I'm trying to make it so that when I select a user from a drop down box (SELECT [UserName], [UserId] FROM [vw_aspnet_Users]) that a label will then display the role next to the selected user. Just in case there is a better way to do it I want it so that the drop down selects the user, the label is just there to provide additional verification that it is the correct user and their current status (admin, moderator, user).
I then want to provide edit and delete buttons (but thats another story!)
I did think something like (SELECT aspnet_Roles.RoleName FROM aspnet_Roles WHERE aspnet_UsersInRoles.RoleId = aspnet_Roles.RoleId) would work but it produces an error.
I want to show processing .gif image while submitting data or fetching data?

I have a code which creates an image in application server and that image has been referred in mail html. After sending mail, image will be deleted in application server. When i open the mail , image is not getting display in the mail.
The reason i guess is , my code is deleting the image before it copied to mail server. I have checked by deleting the image manually.
First i opened the mail(this time image get copied to mail server) and then deleted the image in pplication server. When i open the mail 2nd time, image get display(because image is in mail server i guess)
Again i ran the code, this time before opening mail first time, i deleted the image in application server and opened the mail. Image is not displaying(because image not getting copied to mail server).
here is the way i store my image...
[code]....
how i can retrieve the image from the database and display it in my form?
I use .NET C# , I dynamically create folder to store the image I upload, ex:
strFolder = Server.MapPath("./folder/folder_"+folid+"/")
So I could create different folders according to the page unique id. I have also created a thumbnail image from the image I have upload (cropped ones).
The problem I am trying to figure out is to display these images as a slide show from these dynamically created folder (display thumbnail in the page and clicking the thumbnail need to see the full size image just like slideshow).
I was trying to see examples in jQuery but its just client side. So is there any way to load these images and display as a slide show from the directory. Should I deal with DirectoryInfo in C#? Expecting a simple one.
I've got a ASP.NET site that's located on a local server (MY_SERVER). And one of the things it does is pull up tiff files which are located on another server (ANOTHER_SERVER). The location of each of these files is stored in SQL. I pull up each of these images and am supposed to display them. The problem is:
the files are not named with a tiff extension (does it matter?) they aren't displaying at all.
I am using an Image control to display these images, and I'm not sure if it matters that the extension is not set (does the image control know the difference between an jpg and a tiff without the extension?)
I am guessing the images aren't displaying because they are not on the same server MY_SERVER that the images are located (ANOTHER_SERVER).
edit: actually displaying the tiff files were amazingly simple:
protected void Page_Load(object sender, EventArgs e)
Response.ContentType = "image/png";
new Bitmap(Request.QueryString["ImagePath"]).Save(Response.OutputStream, ImageFormat.Gif);
}
but because the images are located on ANOTHER_SERVER I still can't access them. I may just do a hack where I copy them to a local directory on MY_SERVER but there's gotta be a simple way to fix this. Anyone?
I want to display an image on a page with Image control on it.
I know this is very simple but tweak in my case is that image is available as a stream variable (which I am getting as a response from one of the server) instead of physical file.
Eventually I want to create a control for this with some other feature on it.
My question is how to assign "stream" variable to Image control?
I'm new to asp.net and I am picking it up pretty good. What is pissing me off to no end is why an image control will not display in design view when it works just fine on the local asp development server. I am using VS 2005. The image is part of a master page. The only thing that shows is the red x along with some really small green triangle in the top left. Btw what is that geen triangle all about?

I have one Store Procedure that generating report ..
For storing the data there , i used many temp. tables. There is many Select Query , little less insert and delete query.
Now if there is huge data around 1 lac in temp table my select query taking to much time and also may be insert and delete query
I added Primary key to all auto Increment Field in temp table. Also defined Clustered index on that primary key as unique Clustered index to improve the performance .
But there is not so much improvement in case of huge temp table.
Right now the whole Store Procedure is taking time to complete around 1.5 days or around 30 hours ..
So i want to increase the performance as much that it completes on nearly 3-4 hours.
