Web Forms :: (Image) File Upload Control

Jul 1, 2012

I use these code to uploading image

<asp:UpdatePanel ID="Upbdt" runat="server">
<ContentTemplate>
<asp:ModalPopupExtender DropShadow="true" ID="ModalPopupExtender"
PopupControlID="PnPopup" runat="server" TargetControlID="BtnPopup"
>
</asp:ModalPopupExtender>

[Code] ....

behind code

protected void BtnUpload_Click(object sender, EventArgs e) {
string path = Server.MapPath(".") + "../Upload";
string[] validext = { ".jpg", ".gif", ".png", ".rar" };
string ext =
System.IO.Path.GetExtension(AsyncFileUpload1.PostedFile.FileName);
if (Array.IndexOf(validext, ext.ToLower()) < 0)

[Code] ....

Here in UpdatePanel i have 2 lable :1-lable20    and   2-lblMessage   

These lable show error message when Extension and size of image are out of limit.

Problem is when i.e  I upload  .rar file and click on BtnUpload button it exit from popup window and i cant't see error message i should click on upload button again  untill again show popup window after that i can see error message

I want it doesn't exit from popup window until user enter correct format of image if they don't enter correct format they can see error on popup window.

Accessing Image File Of Client's Machine (without Using File Upload Control)

Apr 14, 2010

I 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?

Web Forms :: Can Upload A File On A Network Share Folder Using File Upload Control

Aug 6, 2010

I want to upload files to the web servers from the client machines.

Can i upload a file on a network share folder using file upload control?

I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?

Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?

VS 2008 File Upload Control - Pass Image Straight To .aspx Page?

Nov 5, 2010

I have read about the file upload control in asp.net and tried it and works great. But I want to know if I can use it for another purpose. I have a video capture control that can be used for webcam apps or anything else. It has a method called HTTPUpload where it will upload an image file to the server using the HTTP upload protocol. My question is can i use the .net FileUpload control for this? And if so, how can I pass the image file straight to the .aspx page without having to submit a button? Would the file be as a query string variable?

Arguments:
WebServer = web server address
WebPage = name of upload web page
Fields = list of 'fieldname' and 'fieldvalue' values delimited with '|'
Files = list of 'fieldname' and 'file path' values delimited with '|'
Returns TRUE if successful, or FALSE otherwise.
Example
vcx.HTTPUpload "[URL] , "upload.asp",
"field1|value1|field2|value2" ,
"file1|c:foldermypic.jpg|file2|c:foldermyvideo.avi"

Valum File Upload - Works In Chrome But Not IE - Image Img = Image.FromStream(Request.InputStream)

Dec 6, 2010

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).
