The class is a ClassName.vb file. Originally is located on app_code folder. After I covert to web application project, it located on old_app_code folder.

|
|
|
|
Just guessing here - but should you move it to app_code in the new project then?
|
|
|
|
|
Just find it out I need to put the project name before the class name:
Dim cls As New ProjectName.ClassName
Thanks for the help.

hi everybody. I am storing an image in database. but when i retrieve it from it, i can't find a way to display it in image control of my form. I am using buffer for uploading and downloading images. i am supposed to store that image on hard drive and then apply the path of that image into image control.
please tell me if is there any other alternative.

This is a good one to Google. There has been a lot written about displaying images in a database on an ASP.NET form - typically the solution will either involve having a dedicated .aspx page that returns the image as a binary stream, or having a custom ASP.NET handler (.ashx) that will retrieve and stream out images. The consuming page would then have something like
<img src='myImagePage.aspx?imageId=42' /> to define the image.
Creating a dedicated .aspx page for this is probably easier - here's an example:

Creating an HTTP handler requires a little more understading, but could pay off for you if you're interested in learning about it. Here is a link that describes HTTP handlers and a second that specifically deals with image display:

Hi,
Is there any way to add items to a datalist manually?
Thanks!
munklefish

Hi munkle. Wouldn't you have to add an item to the DataList's underlying DataSource and rebind?
I'm thinking that maybe you'd use an ArrayList for the datasource, then .Add() items to the arraylist and rebind as necessary?

I really wouldnt know, youre the expert :->! But i guess what your saying would make sense. I was hoping their was a simple answer but obviously not (at least for my purpose).
Thanks!

You have to parse the code for it to become more than plain text. Look at the Page.ParseControl method.

Hi.
I have created and image in the Page_Load event:
Bitmap bm = new Bitmap(300, 300);
Graphics g = Graphics.FromImage(bm);
g.FillRectangle(brush, 50,50,100,100);
g.DrawLine(Pens.WhiteSmoke, 10, 10,180,10);
g.DrawLine(Pens.White,10,10,10,180);
After the line drawing code I added:
bm.Save(Response.OutputStream, ImageFormat.Jpeg);
bm.Save("C:\\mypic.gif", ImageFormat.Jpeg);
bm.Dispose();
g.Dispose();
I would like to be able to save that image to my hard drive but I haven´t been able to do that, can anyone help me? This compiles just fine but when I want to view it in the browser and an error occurs. What am I doing wrong? Can someone please show me the error of my ways?
Thanks,
F

So what is the error you are getting? Are you certain the account running the ASP.NET worker process has permission to write to the C:\ directory?
|
|
|
|

Hi.
I am just running this on my own PC and I pretty much copied the code from a book to learn and modify later. Everything seems to be OK but when I right-click and choose view in browser I get:
A generic error occurred in GDI+ and this line gets the red color:
bm.Save("C:\\Mypic.gif", ImageFormat.Jpeg);
This just doesn´t make sense
F

Perhaps you need to look at the InnerException of the exception you are getting? The outer exception may say "generic error", but often the InnerException will have more details.
I'm still betting that your ASP.NET worker process does not have permission to write to your C:\ directory. Any comment on that?

Hi.
I am not really following you If you are right, how do we fix the problem?
F

Hi.
It just so happens that I have 2 hard drives, c and e. I changed the code to:
bm.Save("e:\\mypic.gif",ImageFormat.Jpeg);
and it made all the difference in the world , the image appears on drive e. You were absolutely right!! Very impressive. On the other hand I don´t understand why this small change makes such a big difference? Do you have any suggestions on how I can make the pic save to c?
