I've been playing with the FileUpload control for an upcoming project where the user is allowed to upload up to five files at once, but each file can only be 5MB in size. Simple enough all I would need to do is add in the httpRuntime element to the web.config and up the file size and timeout.
[Code]....
what I'm really getting at is there a better way to trap if the file size is too large before processing while using the FileUpload control. I would like to be able to keep the user on the same page but update a label control.
If I want to increase the upload size which part of should I edit in the code below:
<system.web>
<httpRuntime executionTimeout="240" maxRequestLength="20480" />
<compilation debug="true" targetFramework="4.0"/> </system.web>

The FileUpload control doesn't have an OnClick() event so when i hit Upload i don't know what happens with the uploaded file in the back.
what i'm trying to do is choose a file with the FileUpload control, preview it in the Image control and then save it in an SQL Server 2008 database in an "image" field.

View 1 Repliesi am working on an ecommerce application, user will be uploading several images of a product, instead of stripping the size (i.e the KB or MB size) after uploading it on the server, i want to strip the size of image before uploading it to the server ( bringing the size from any thing over 30KB down to 30KB) i.e on the client machine itself and then upload it to the server. i understand that this requires a download on the client machine which makes me ask the following questions :
a. can i use a java control in dotnet since java control can be used on all OSes
b. is there any dotnet control that might be userfriendly to all OSes
How can I display photogarphs in an image control so that they are all the same size for an online catalogue without distorting the actual image.
I have taken the photos with a digital camera, loaded them in to Photoshop, cropped the image and finally resized the images to an acceptable size (while constraning proportions to avoid image distorsion).
The problem is that the images all have different height dimensions as while resizing i was able to choose the width that I wanted but as I had to constrain proportions to avoid distorsion, it caused the heights of the images to differ.
On my web form I have an image control that is set to the same width as the images but as the heights of the images differ from one and other, it is impossible for me to set a fixed height that will prevent some of the images being distorted when displayed in the image control.
