File download from 3 servers not working.

Posted By:      Posted Date: September 22, 2010    Points: 0   Category :ASP.Net
 

Hi guys,

We have a problem where in the user can download files from an email. A link that will redirect to a page where the code to download the file resides. Before the download the user needs to be logged in to the system for security. The problem is that sometimes for whatever reason when the user clicks the link the download dialog box does not appear and just a blank white page. It happens only on our staging environment where we have 3 servers.. We can't reproduce this in our dev and test env. where we only have one server.

We need help.. thanks.

Below is the actual code.

  Private Sub DownloadFile()
        Dim path As String = ConfigurationManager.AppSettings("JobApplicationDocuments")
        path &= applicationClientId & "\" & jobId & "\" & jobApplicationId & "\" & fileName

        If (System.IO.File.Exists(path)) Then
            Dim fs As System.IO.FileStream = System.IO.File.OpenRead(path)
            Dim file As System.IO.FileInfo = New System.IO.FileInfo(path)
            If file.Exists Then
                Response.Clear()
                Response.AddHeader("Content-Disposition", "attachment; filename=" & orginalFileName.Replace(" ", "_"))

New off line application working with sdf file. Need advice

  

Hey Folks


I am working on a project currently where I need to get data out of a 3rd party vendor's software that uses a .sdf file I looked this up and its a SQL CE file. I was hoping to just link to with with access but thats apparently not going to happen. I need to link to the database extract data from it to a csv file for later use. I also and most important I need to get the data from it and create a report that can be printed while on a customers site that my or may not have web access so I need for this program to be on and off line. I had my webapplication that I have been working on open and was able to bring up the sdf file under the server exploere however I can't seem to get anything out of it when I try to do grid views or detail views errors out.

File Download Problem

  

Hi everyone,

I am using a download handler to handle the downloading of files from my website.  I am using a slightly modified code from the Microsoft article http://support.microsoft.com/kb/812406

Everything is working fine and downloading, even with large files, but it does not show the file size for any of the files to download. Even if theyre really small.

Here is my code for the handler

public class DownloadHandler : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            string path = "";
            try
            {
                path = context.Server.UrlDecode(context.Request.QueryString["src"]).DecryptString();
            }
            catch(Exception ex)
            {
                context.Response.Write(ex.Message);
            }
            System.IO.Stream iStream = null;

            byte[] buffer = new Byte[10000];

            int length;

            long dataToRead;

            string filename = System.IO.Path.GetFileName(path);

            try
            {
                iStream = new System.IO.FileStream(context.Server.MapPath("~/" + path), System.IO.FileMode.Open,
                            System.IO.FileAccess.Read, System.IO.FileShare.Read);

The file reached the maximum download limit. Check that the full text of the document can be meaning

  

Hi,

I'm facing an issue with the indexing.

I have 1 WFE+Index server+DB server.

Index server is not installed with MS FIlter pack 1.0

When crawling, the there will be document with warning in crawl log:
The file reached the maximum download limit. Check that the full text of the document can be meaningfully crawled.

Documents that with warning are such as doc, ppt, xls, docs, ppts and many others.
However, I view into the successful crawled document, there are doucments with ext doc and ppt.

For large file index, there are MaxGrowthFactor + MaxDownLoadSize required to be added into the index server.


As my understanding is, MS Filter Pack should installed into index server(already did, correct me if i'm wrong).

I looked into the Office SharePoint Seach(CA>Services in farm), if the server is appointed to "Use this server as indexing server", then MS Filter Pack is suppose to be installed into that particular server as well.

At the bottom, there also has another option is "Use all web front end for crawling".

The question here is, IF the option "Use all web front end for crawling" is selected.
Does the WED FRONT END Server required to installed the Ms Filte

How to initiate a file download from withing UpdatePanel?

  
Hi all, I'm building dynamically a series of ImageButton controls, and I want to assign them a hyperlink for downloading files. So say you got a dropdownlist of 3 items 1,2 and 3, if you select 1 it creates one imagebutton and pointrs to fileA, if you select 2 it creates two imagebuttons and the first one points to fileA and the second one to fileB and so on... Everything is wrapped in an UpdatePanel to avoid postbacks. I have a problem binding the download link in the ImageButton.navigateurl, and then downloading it. I don't know how to do it...   protected void Button1_Click(object sender, EventArgs e)    {        Panel myPanel = (Panel)UpdatePanel1.FindControl("Panel1");             string[] Uploaders = new string[CheckBoxList1.Items.Count -1];        for(int i = 0; i < CheckBoxList1.Items.Count; i++)        {            if(CheckBoxList1.Items[i].Selected)                  Uploaders[i] = CheckBoxList1.Items[i].Text;         }              my

Drag drop functinality not working on Explore View control for file containing special characters in

  
We have created a control which uses explorer view control for file drag and drop. This functinality works fine for a file having filename without special characters but it gives an error if we drag and drop a file having special characters in the file name. The reason for this is Sharepoint uses WebDAV protocol for file transfer to the Sharepoint document library and WebDAV protocol has limitation that it does'nt accept file with special characters. Please let me know the way how I can accomplish drag and drop of file with special characters in file name, onto Explorer View control with WebDAV.

Client download .csv file from server using Response.TransmitFile

  
I am using the code below to enable clients to download a .csv file from my server.The problem I am having is that when the file is saved to the client computer the file name is prefixed and suffixed with an underscore which leads to a file type of .csv_ which is obviously not a recognised file type.How can I strip the underscores from the file name at the transmit stage?        Dim FileName As String = LstBox1.SelectedItem.ToString        Dim FilePath As String = "~/temp" & FileName        Response.Clear()        Response.ContentType = "text/csv"        Response.AddHeader("Content-Disposition", "attachment; filename=\" & FileName & "\")        Response.TransmitFile(FilePath)        Response.End()

Task scheduler and System.IO.File.WriteAllText() not working properly

  
I have a simple console application that has this in mainline:  Console.WriteLine(System.String.Format("the current directory is: {0}", System.IO.Directory.GetCurrentDirectory())); System.IO. File.WriteAllText(@"test.txt", "new contents");   Console.ReadLine(); I compile this in VS 2010 and copy the EXE to a directory named "c:\test".  When I run this code in two different OS's via "Task Scheduler" and "Scheduled Task" I get different results.   In Windows Server 2003 R2 "Scheduled Task" this code will create a file as I would expect, c:\test\test.txt with the proper contents written to it.  When I run this same code on Windows 2008 R2 (64 bit version) "Task Scheduler" it writes the expected contents to an unexpected location, c:\C:\Windows\SysWOW64\test.txt. In both environments if I run the exe's from a command line, it writes to c:\test\test.txt as I would expect. As I understand it, if you don't fully qualify the file name in the first parameter of the WriteAllText method it will write the contents to the file in the directory of the executable however this seems to break down when running in the Windows 2008 Task Scheduler.  I know I can fully qualify the file name or put the expected path in a
