View 2 Replieshow to upload image on to server having specified path name. and for each time the image path need to change.
i have some idea in my mind...
i need to use asp:fileupload control as follows
<asp:fileupload id ="fileupload1" runat ="server"/>
in codebehid
how to mention file name in vb.net like fileupload1.saveas(serverpath addwith filename addwith .jpg) serverpath is fixed filename comefrom database ... like datafield-image and i need to check the image should be jpeg
In asp.net, we have uploaded a .jpeg file and saved this as bitmap image using following code
HttpPostedFile uploadFile;
System.IO.Stream stream = uploadFile.InputStream;
using (System.Drawing.Image imgSource = System.Drawing.Bitmap.FromStream(stream))
{
System.Drawing.Image.GetThumbnailImageAbort myCallback = new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);
using (System.Drawing.Image imgThumbnail = imgSource.GetThumbnailImage(imgSource.Width, imgSource.Height, myCallback, IntPtr.Zero))
{
imgThumbnail.Save(filePath, System.Drawing.Imaging.ImageFormat.Jpeg);
imgThumbnail.Dispose();
}
imgSource.Dispose();
}
stream.Close();
stream.Flush();
stream.Dispose();
After upload, if we perfrom delete operation it throws error. We are following code to do so;
if (File.Exists(filePath))
{
File.Delete(filePath);
}
The exception says:The process cannot access the file 'abc.jpg' because it is being used by another process.

I'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).

View 3 RepliesI want to access one image file residing in C: of the client's machine. I know with the help of file upload control (or say input type=file), this would be easy. Due to nature of my application (Its a KIOSK application), user is not expected to select file. I am just wondering how should I implement reading file without using file upload control. I want to store this file in Images folder of server. I am beginner to WCF. Should I look towards WCF?

View 2 RepliesI am using FileUpload control to facilitate Image file upload on my website. I want to restrict a user to upload only Image file. I am using
if (fupFirmLogo.PostedFile.ContentType == "image/Jpeg")
{
}
to check if the file is a image or not. I want to allow all image extensions like PNG, GiF, Jpeg, tif , BMP etc. How should I do it.
I have file upload UI element in which the user will upload images. Here I have to validate the height and width of the image in client side. Is it possible to find the size of the image having only the file path in JS?Note: If No, is there any other way to find the dimensions in Client side?
View 4 RepliesI have an 'Attach image button' in my web page, I don't want see the the file upload control cannot use any third party tools in my page. On the click of the 'Attach image button' it will directly shows the browser's directory window and select the file from that and can directly uploads to the server.
