I know about SWFUpload, how can i configure it with ashx on server side.
any tutorial how i can use FLASH objects to transfer files from client to server. i been looking for such tutorial for a while that uses flash object on client side and sends file info using bytes array to the server. also i want to reduce the size of the file on the client side before sending to safe bandwidth.
I have tried doing a post back and creating a RaisePostBack event handler method (both in the .aspx page and the .ascx user control) but no luck.
I created a method which instantiates an Attachment using a string and calls the corresponding Delete() method for the Attachment object.
ASP.NET server controls has a few categories, for example, normal ones e.g. TextBox, Button which can be done in HTML/JS; Validation controls: can be done in JS; Login controls: I have seen them implemented in JS. Data bound controls: not sure, but maybe JS can work directly with databases, implementing controls like photo slider. So in the time span of next 5-10 years, will server-side web programming model fall out of mainstream and be replaced by JS/Ajax that interacts directly with databases?
I have a async file upload control and I am doing client side validation for Image."OnClientuploadstarted" I am doing the client side validation.My validation is working fine but my problem is that the file upload control text box goes green (i.e file is loaded on the server) even if the validation fails which is I dont want.What I want is when the client side validation fails the file does not gets loaded on the server and the Async file upload textbox does not goes green.I have goggled but have not found a suitable solution.
I couldn't upload anythink to a server using FileUpload control (access denied exception). I changed permissions for required folder and gave aspnet user full access. It did not work (I got access denied exception). Than I changed permissions again and gave full access to all users on the machine - now upload works. As far as I understand, it makes my site vulnerable and I should give full access to only one user. Could anyone tell me which user IIS 7.5 uses?
i made a file uploader to folder named (Books) and i saved the name and the bath of the uploaded file to my DataBase but when i wanna download the uploaded file from the server ? how i make it ? by hyperlink ?
I am working on some project where I am needed to allow users to upload files, but only in pdf and .doc format. Now I know how to let users upload files, but I do not know how to check whether an uploading files is pdf and .doc or not. How could I know that? And how could I know the size of each file, for the file should be no greater than 3 MB?
Also, I have alloted a separate folder for the files that are uploaded by users. I have one page that displays the links to download the files in that folder. I needed to know how could I keep the track of the folder, for the files get uploaded every time? Or in other words, how could my 'downloads page' know about the files in that folder and create links for each file in that folder for the download? Also, if I create a link of a file for downloading purposes, will the file be downloaded when one clicks the link?
I have some code that allows users to upload file attachments into a varbinary(max) column in SQL Server from their web browser. It has been working perfectly fine for almost two years, but all of a sudden it stopped working. And it stopped working on only the production database server -- it still works fine on the development server.
I can only conclude that the code is fine and there is something up with the instance of SQL Server itself. But I have no idea how to isolate the problem.
I insert a record into the ATTACHMENT table, only inserting non-binary data like the title and the content type, and then chunk-upload the uploaded file using the following code:
code with windows application and it works in a good way and files uploaded to server successfully using text box control and open file dialog,but when I tried it with upload control on Asp.net application it doesn't work and gives error : Could not find file .......this is my code in windows application under button click FileInfo toUpload = new FileInfo(this.txtFile.Text); FtpWebRequest request = (FtpWebRequest)WebRequest.Create(this.txtAddress.Text + "/" + toUpload.Name ); request.Method = WebRequestMethods.Ftp.UploadFile;
I have made an application for some customer that I'm going to transfer to a webhotel.I want to make sure that the application is not copied and used elsewhere without my knowledge. So I have thought of stripping the aspx files from their code behind, that is not the aspx.cs file itself. But from all code inside the cs file, not the one that is automatically generated like page_load etc, but everything else. And when done, then just upload the compiled DLL file(s). Does this work? Are there something to be mindful of if I carry out with this plan.
I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
Now, this works fine on my home computer. Is there anything I'll need to do with IIS or ASP.NET (possibly in web.config) for this to work properly on a production machine? Settings or permissions that may need changing?...
It will be on Window 2003 with IIS6 and ASP.NET 3.5 SP1.
I'm using the asyncfileupload control, and have it woking to an extent. I'm able to upload the image to the relevant directory and save it's path to the database.The problem I'm having is that I am unable to upload a 2nd file once the first has completed without refreshing the page.
