Delete file Asyncronously that is uploaded by AsyncUploader

Posted By:      Posted Date: September 25, 2010    Points: 0   Category :ASP.Net


Suppose after Uploading file,i want to delete a particular file ,for that i have added a link, that calls a Web Service method to delete file stored in DataBase. That link is added throug JavaScript in OnClientUploadComplete JavaScript function. And this Delete link calls another JavaScript function that in turn calls Web Service method. But that delete link should contain some specified arguments against which file has to be deleted. I am confused how to pass that argument to dynamically created Link.

Please help

Programmatically delete a .webpart file from wpcatalogs folder from an IIS website


We are using a third party wsp in our solution which directly adds the web parts into the web application store rather than the web part gallery(References to them are present in IIS site's wpcatalog directory). We want to remove these web part files so that the users will not be able to add these web parts to pages directly. Or any other modification so that users will not be able to add these directly. Is there a way we can do this programmatically?

Cannot read stream from uploaded file

I have a file upload which uploads a file and gets read into a byte array.int FileLength = File1.PostedFile.ContentLength; if (File1.PostedFile != null && File1.HasFile) { Stream fStream = File1.PostedFile.InputStream; byte[] contents = new byte[fStream.Length]; fStream.Read(contents, 0, (int)fStream.Length); fStream.Close(); fStream.Dispose(); The problem is, the fStream.Read seems to have a problem reading the stream. When I debug it, and the value of "contents" appears to be empty. The file gets uploaded as a corrupted file.

How to delete an image file assigned to a PictureBox xontrol ?

In a Windows form application, some image files are assigned to PictureBox controls. I am trying to delete those image files. The first approach [1] with "Image.FromFile" gives an error message of "Another process is using this image file", although "Image.Dispose()" is executed. The second approach [2] using "Image.FromStream" results (X) images for PictureBoxes and Buttons, if "fs.Close()" is inclided. Without "fs.Close()", it gives the same error message of "Another process is using...". How can I display images properly and delete those images files ? Thanks [1] pictureBoxSelected.Image = Image.FromFile(@actualImage); . . . pictureBoxSelected.Image.Dispose(); pictureBoxSelected.Image = Image.FromFile(@tempImage);                                                if (System.IO.File.Exists(actualImage) == true) {     System.IO.File.Delete(actualImage); } [2] FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read); pictureBox.Image = System.Drawing.Image.FromStream(fs); fs.Close();

Log file WSS_AdminService.log - can i delete it?

Hi, I've noticed that the size of a file WSS_AdminService.log every user profile setting eg. in C:\Documents and Settings\Default User\Local Settings\Temp is about 2GB currently. I understand that this file is updated by wssadmin.exe (the Windows SharePoint Services Administration service). questions: 1. we have many users who are no longer using the account to login to the server, can i delete teh file then? 2. is there a way that i can allow only a single file WSS_AdminService.log in a specific user account to be access by wssadmin.exe? in this case we can save more HDD space. because, if we have more than 50 users account, then 50 * 2GB and it's already 100GB. instead of 100GB, can we just make it 2GB and this file is share by all the sharepoint users? thanks. Sam. Does anyone have any insight into how I might alter what is logged or how often, or even just to persuade it to 'housekeep' better, as the file continues to grow (reaching 750MB on the first server I noticed this on)? As far as I can see it is not related to the Diagnostic logging settings in Central Administration > Operations. Renaming the file to append a date on a regular basis is my current solution - a new copy is then created by WSS Admin on its next log cycle.

uploading a file with wcf works fine with local drive, but only 4096 kb uploaded when I use unc stor

Hello I'm writing a wcf service for uploading files to a server. It works fine when I try to upload the file to the servers local c:/ drive, but if I use a UNC path only 4096 kb is stored. It actually looks like part of the file is lost while storing it with writeStream.Write(buffer, 0, bytesRead);, because I wrote the bytesread to an sql table and the number of elements are always the same no matter how many times I upload the file, but the stored file is always different sizes, ranging from 1996 kb to 4092 kb.   I'm using IIS 7.5 on a windows 7 enterprise machine. My IIS is using a administrator account for the application pool, so it should not be a problem with permissions.   My wcf method uses Stream to upload the file in chunks    public void UploadFile(RemoteFileInfo request)         { //some methods to set the filepath                                   int chunkSize = 4096;                                 byte[] buffer = new byte[chunkSize];                                 Stream writeStream = new FileStream(filePath, FileMode.CreateNew, FileAccess.Write);  &
