Output Blank Text File

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :ASP.Net
Hello all,I have come across an interesting edge case when using Response.Write. I couldn't find another forum to post this in, so I'm putting it here, even though its not really "getting started" in my mind.The scenario goes like this:I have a ASPX page that stores data in a string using a comma delimited text format, which is then written to the response stream using Response.Write. Whenever there is data, this works fine. But, when there is no data, the string generated is empty and a basic HTML page structure magically appears in the output even though it isn't even in the .ASPX file. What I'd like to do is simply return a blank text file (not even a space).I've tried using Response.Clear to ensure that there is no content in the response stream. I've tried setting the content type and even specifying a filename in the response header. I am, of course, also using Response.End after the call to Response.Write, but all to no avail. The response is always a basic HTML structure.To eliminate other possibilities, I've set up a test. Just a default .ASPX Web form with the following PageLoad method: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Response.ContentType = "text/plain" Response.Clear() Response.Write("") Response.End() End Sub

How to output data from master detail tables into text file but on different lines.



I have a requirement to output data from two tables, a master table and a detail table, to a text file such that the output looks like the following:

master record 1

detail record  1 1

detail record   1 2

master record 2

detail record  2 1

master record 3

detail record 3 1

detail record 3 2

detail record 3 3



Is this possible in one query?  I am sufficiently familiar with the bcp utility to do the output from any of the tables separately but have some difficulty with doing it for the two tables and have the result structured as outlined above.

Removing blank line from a text file


Hi i have a comma deliminated text file which i am using to generate a multidimensional array using the following code:

Dim DefinitiveDatabase As String(,)
    Dim strfilename As String = (Server.MapPath("~\Definitive database.txt"))
    Dim num_rows As Long
    Dim num_cols As Long
    Dim x As Integer
    Dim y As Integer
    Dim value As Integer
    Dim ConditionName As String
    Dim strlines() As String
    Dim strline() As String
    Dim tmpstream As StreamReader = File.OpenText(strfilename)

strlines = tmpstream.ReadToEnd().Split(Environment.NewLine)
        num_rows = UBound(strlines)
        strline = strlines(0).Split(",")
        num_cols = UBound(strline)
        ReDim DefinitiveDatabase(num_rows, num_cols)
        For x = 0 To num_rows
            strline = strlines(x).Split(",")
            For y = 0 To num_col

Writing to a text file



I have the following  subroutine in an asp.net application class. The subroutine writes data to a text file upon application login.   My question is that if this function was called at the same time by two different  users would it cause any kind of error. Is there a need for a try catch?

 Public Shared Sub writeToLogFile(ByVal UserName  As String)
        Dim strLogMessage As String = String.Empty
        Dim strLogFile As String = System.Web.HttpContext.Current.Server.MapPath("~/Log.txt") Dim swLog As StreamWriter
        strLogMessage = DateTime.Now.ToShortDateString().ToString()  " ==> " & UserName

        If Not File.Exists(strLogFile) Then
            swLog = New StreamWriter(strLogFile)
            swLog = File.AppendText(strLogFile)
        End If


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



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

SQL Agent Jobstep output file contains automatically generated header

Hi,   I've created a stored procedure that creates a script to create a number of objects within the database (based on what existing objects are in the database).  From Management Studio, this works fine, and the output is exactly as I want it.   I'm now trying to create a job that will execute this stored procedure, and deposit the results into a file somewhere on the server.  When the job runs, the script is created in the correct place and is essentially ok.   However, there are a couple of questions I'd like to ask.   Why does SQL Server Agent put a header at the top of the output file?  I was hoping to be able to use that output file 'as is' and execute it automatically to recreate my objects when required.  (Obviously, I can manually remove the header, but this is an inconvenience in this situation).  How do I stop it?   Also, when executed from SSMS, the output is correctly line-spaced.  But, the output from the scheduled job adds an extra line between each line of text, which is, again, inconvenient.  Why does it do this, and how can I prevent this (again, without manually editting the output)?   Any thoughts and help greatly appreciated.   Cheers Simon

Deleting Last Line of Text in a text file

Hi, I needed some help on the best way to delete the last line of  text in a text file. I have a subroutine that looks like this, but it is missing some code. Could anyone advise me on this? Dim strLogFile As String = System.Web.HttpContext.Current.Server.MapPath("~/Log.txt")         Dim fs As New FileStream(strLogFile, FileMode.Open, FileAccess.ReadWrite, FileShare.None)         Dim swLog As New StreamReader(fs)         Dim array As String()         Dim value As String = swLog.ReadToEnd ''Array that holds the lines of the text file.         array = value.Split(vbCrLf)        ''code for deleting last line: . . .  fs.Close()

Data loading from text file

Consistently running out of page file memory with full text indexer

Using MS SQL Server 2008 SP1 x64 Standard Edtion on Windows 2008 R2 Enterprise, I'm about to full-text index for the first time 1 table and 2 views. The table contains about 250'000 entries with a data space of 180 MB. As soon as I activate the full text indexing, the fdhost.exe task starts to consume slowly but surely all the available page file space (this can be easily watched using the Resource Monitor and the Commit Charge graph on the memory tab). Once all the virtual memory has been consumed, the server becomes unusable since it can't open any new windows any more, and RDP stops working. The machine specs are as follows: 12 GB of RAM 80 GB free on hard disk out of 136 GB 8 CPUs Custom size paging file with sizes between 24 GB - 60 GB (originally, this was system managed size, but then the server ran out of memory sooner) Max SQL server memory set to 6 GB (first 10 GB, then 8 GB) I've set the max fulltext crawl range to 8. During the indexing, the 8 CPUs are bit busy for a while, but not excessively. What is astonishing is that there is almost no use of physical memory during the indexing (I can see an increase from 2 GB to 3 GB which still leaves plenty of RAM available). Does anybody have an idea how I can convince fdhost.exe to consume physical memory and leave the paging memory alone? Or what else can I try?

Read a text file on another server from a web page

How do I read/write a text file on another server from a web page. I get the error "Access to the path '//Server2/mydatafiles/test.txt' is denied". I do not get the error if I am running the browser on the server where the files exist. I think I need to set permissions on the destination server in some way.   Can you help? Thanks  

FileStreamResult how to rename the output file?????

i have an action to return a pdf file in my controller,if the return file is for downloading, the following code can be used to modify filename successfully.HttpContext.Response.AddHeader("content-disposition", "attachment; filename=form.pdf");HOWEVER, i found that when the pdf file was returned to browser( rather than a pop up window to download), the filename always remain same as the action name! (when u right click file and try to save it on ur hard disk), i was wondering if there is a automatic way to rename the file rather than "right click" and "save as" manually.so  can anyone tell me how to rename the outputfile when it is shown in the browser?

How to put text from an external text file into a text box on a report.

Hi all, We're moving from our legacy reporting app to SQL Server Reporting Services 2008 and I'm converting our reports slowly but surely.  In our organization, one of our departments sends out letters that have standard marketing messages and disclaimers that they put into .rtf files.  Currently, our reporting application has an RTF box control that can do that fairly easily.  I've not found a similar control in SSRS 2008.  My thought, then, was to use a piece of embedded code in the report to grab the necessary text from the file and reference it in the Value of a Placeholder (using a Code.<FunctionName>.ToString() statement) - using HTML tags for the necessary formatting for those files. I don't care if I have to convert the existing RTF files to HTML files to do this, that's not an issue.  The code I'd come up with is this:  Public Function GetTextFile(ByVal strFileName as String) As String Dim oFile as System.IO.File Dim oRead as System.IO.StreamReader oRead = oFile.OpenText(strFileName) GetTextFile = oRead.ReadToEnd() End Function And the Expression I was using to get the text from the file is:  =Code.GetTextFile("HTMLTest.txt").ToString() Where "HTMLTest.txt" is the file name that I'm using.  The text itself is just a line of text with some HTML tags included for formatting - bold, color,

Saving a generated text file

 I have an application that collects data and puts it in a text file.  When the data collection is complete the UI offers the user the opportunity to save or open the text file with a dialog box using this code: Response.Clear(); Response.ClearHeaders(); Response.AppendHeader("Content-Disposition", "attachment; filename=" + outputFilename + ";"); Response.Cache.SetCacheability(HttpCacheability.Private); Response.ContentType = "text/plain"; Response.WriteFile(outputFilePath + outputFilename); Response.End(); Response.Flush(); The problem is this.  The starting interface allows the user to select a large number of data gathering points.  If all are selected the program will run for about 90 minutes.  Sometimes it will present the dialog box, sometimes not.  Sometimes it will present the dialog box, but regardless of whether the user selects save or open, the dialog box simply disappears, and the data text file is neither displayed nor saved to the client system. When fewer data gather points are selected, and the program runs for 15 minutes or less, there is no problem.  The resulting data can be saved or displayed. The actual data text file is initially stored in the temporary path directory on the web server.  On at least one occasion, where the dialog box disappeared, I was able to
