File Upload Path Problem

[jphaycock@googlemail.com]

Hi

I have a webform in a sub folder called admin. The form has a file
upload control on it. I'm trying to upload an image file to the root
images folder of the app like this:

filePath = "~/images/" + myUploadControl .FileName;
myUploadControl .SaveAs(filePat h);

I get an error about a rooted path:

There was a problem uploading the file: System.Web.Http Exception: The
SaveAs method is configured to require a rooted path and the path bla
bla bla is not rooted.

Can anyone tell me how to do this. I've wasted an entire morning on it
and have a tight deadline looming

Thanks

John

What happens if you try:

filePath = Server.MapPath( "~/images/" + myUploadControl .FileName);

Hi Mark Thank you for your help

That actually works Mark but I have a fresh problem now.

When the app first starts it displays an image in a literal. The url
for the image is stored in a database field in this format :

http://localhost/myapp/images/myimage.jpg

I then use code like this to get the literal to display the image:

string pageBanner = rs[1].ToString().Tri m();
litIMG.Text = "<img src='" + pageBanner + "' alt='Page Banner' />";

When I upload the new image with the file upload it is getting stored
in the database like this:

C:\Inetpub\wwwr oot\myapp\image s\myimage.jpg

When I try to load this image into the literal like described above
the image does not render. I looked in the source code and it's
getting built properly (<img src='C:\Inetpub \wwwroot\myapp\ images
\myimage.jpg'bu t it isn't rendering.

Is there a way to map this absolute path back into a web path before I
send it to the literal?

Sorry for the long winded reply :)

Not as far as I know:

Since you're already storing the absolute path in the database, why not
store the relative path too...?

Cheers Mark

I don't know why I didn't think of this sooner but I'm just saving the
filename to the database now and hard coding the path. I can do this
since the path will always be the same.

The main thing is that the fileUpload is working thanks to you.

All the best

John
