I'm working for a graphical company and I'm making a webapplication at the moment. In this application, users can upload images. Before I let them upload an image, I want to check the resolution of it (dpi = min. 300dpi). How can I do this?
View 7 RepliesOn windows server 2008 can I have a web service or something I can query from a C# application as to the display properties (resolution (height & width)). The C# application does not run on the server so I cannot just detect it from the application itself.ddition to help explain why:I will have a user named "display" and that will be logged on displaying a website (on the server) and I want to be able to check the display from the desktop application so the user knows what resolution to design a template for. The resolution will change from different displays so it can't be a set value

I'm having an image in my page displayed to clients form a folder under same apllication folder,I also have a form in the same page that accepts an image file to be uploaded. The image that is uploaded via this form should take the place of the image that's displayed in the page with the name newly givven at runtime. The new image should be uploaded in the same directory with the new name provided, which means it overwrites the previous image.

This user control i put several pages. When i goto that perticular page i want change background image of menu item which related to that page.
I have to insert default image into databse..when no image is selected from fileupload control.. Here is code...not working for default image...
if (FileUpload1.HasFile){string FileName = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
FileUpload1.SaveAs(Server.MapPath("~/UPLOADEDFILES/" + FileName));
feedBack.Attachments.Add(new Attachment(FileUpload1.PostedFile.InputStream, FileName));
} else {
string filename="~/images/"+ "sun.gif";filename.pPropertyImage = filename;FileUpload1.SaveAs(MapPath(filename));}
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.
View 1 RepliesI'm using a slightly modified version of Valum's upload [github link], I've modified it to upload to a database but haven't modified the javascript that it is using to get the file into the Request as an InputStream. The following line of code is failing in IE 8 but is confirmed to work in Chrome. using (Image imgInput = Image.FromStream(Request.InputStream)) The error received is "Parameter not valid". It appears to be having an issue with the Input Stream being used but it exists/has data (not sure how to validate if the data is good or not).
