VS 2008 Stream.Read Error

Aug 31, 2010

We have a process that calles a url to pull an image (in this case a .tif image) and it calls this function which works most of the time but recently is getting errors. If I step through the While loop of a 92k file it gets to the end and then errors on the following line:

nBytesRead = stStream.Read(baBytes, 0, MAX_BUF)

I have added a Try/End Try statement which appears to work but is there a better option?
The error I get is:

System.IO.IOException: Unable to read data from the transport connection: The connection was closed.

Code:
Private Function ReadAsByteArray(ByVal stStream As Stream) As Byte()
Dim msBuffer As New MemoryStream()
Dim swWriter As New StreamWriter(msBuffer)
Dim nTotalBytesRead As Integer
Dim nBytesRead As Integer
Dim baBytes(MAX_BUF) As Byte
nTotalBytesRead = 0
nBytesRead = MAX_BUF
While True
'ORIGINALLY THE TRY IS NOT THERE
Try
nBytesRead = stStream.Read(baBytes, 0, MAX_BUF)......

C# - How To Safely Read From A Stream

Nov 11, 2010

byte[] bytes = new byte[uploader.UploadedFiles[0].InputStream.Length];
uploader.UploadedFiles[0].InputStream.Read(bytes, 0, bytes.Length);
var storedFile = new document();
string strFullPath = uploader.UploadedFiles[0].FileName;
string strFileName = Path.GetFileName(strFullPath);
storedFile.document_id = Guid.NewGuid();
storedFile.content_type = uploader.UploadedFiles[0].ContentType;
storedFile.original_name = strFileName;
storedFile.file_data = bytes;
storedFile.date_created = DateTime.Now;
db.documents.InsertOnSubmit(storedFile);
db.SubmitChanges();

If:

Reading from a stream in a single call to Read is very dangerous. You're assuming all the data will be made available immediately, which isn't always the case. You should always loop round, reading until there's no more data.

How should I change the above code to make it 'less dangerous'?

Outputstream - Can Get Read Access To The HTTP Output Stream In Web Application

Feb 22, 2010

I would like to read all content that's been written to the output stream. I'm attempting to do this using an HTTP module, and it seems like the obvious timing would be when handling the PreSendRequestContent event.

However, if the output stream seems to be set to write-only, as I can't read using a StreamReader. Is there a way I read and re-write the content without writing my own IIS module?

Stream.read Method Accepts Length As Integer Type ?

Aug 30, 2010

i am trying to read file from a stream.

and i am using stream.read method to read the bytes. So the code goes like below

FileByteStream.Read(buffer, 0, outputMessage.FileByteStream.Length)

Now the above gives me error because the last parameter "outputMessage.FileByteStream.Length" returns a long type value but the method expects an integer type.

VS 2008 - Read Value From Config File

Sep 13, 2011

I have code that reads a value from a config file (not web.config) given a key. It looks like this:

Code:
Public Shared Function GetCustomConfig(ByVal ValuetoGet As String, ByVal ConfigFileValue As String) As String
Dim Returnvalue As String = String.Empty
LoadConfig(ConfigFileValue)
For Each KeyValue As String In AppSettings.Keys
If KeyValue = ValuetoGet Then
Returnvalue = AppSettings.Item(KeyValue).ToString
End If
Next

Return Returnvalue
End Function

So if my config file which is named my.config has this entry: <add key="TempArea" value="c:Temp"/>I would call GetCustomerConfig("TempArea", "my.config") and the function would return "c:Temp". Most of the time this is what happens. But sometimes I get an exception: Collection was modified after the enumerator was instantiated.

Is there a better way to get the value given the key? This is code written long ago by my predecessor, and I am not sure I want to use it anymore. If I do use it, I will have to do something so that it is more reliable.

VS 2008 - How To Read IFrame Hidden Input Value

Feb 9, 2012

I'm using jQuery to build an IFRAME and pass some hidden input values to a Download.aspx page - jQuery code looks like this

Code:
$('<form action="'+ url +'" method="'+ (method||'post') + '" target="iframeX">'+inputs+'</form>')
.appendTo('body').submit().remove();

The inputs variable looks like this

<input type="hidden" name="filename" value="mit-license.txt" />

And the top of the Download.aspx code behind looks like this

Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim ctx As HttpContext = HttpContext.Current
Dim response As HttpResponse = ctx.Response
Dim sFile As String = "mit-license.txt" ' Request.QueryString("filename").ToString

[Code] ....

I could not find the INPUT value - where does it pass in? I checked the "sender" and the ctx objects and could not find it... I hardwired the mit-license.txt filename to prove that the download works...

VS 2008 - Popup Window Can't Read A Text Box

Mar 5, 2012

I have a popup window (.aspx page). It will called from a parent .aspx page. All I want to do is read the name of the parent aspx page. I can do that also without issue. Based on the name of the parent window, in the page_load event of the popup window, I want to execute some code.

But the only catch is I am not able to read the parent window name until the page_load event complets the execution.

1. calling popup window from parent window.

Code:
function OpenWindow_HistoricalRuns() {
var windowIncsimHistRuns = window.open('MVal.aspx', 'Market', 'width=350,height=425,scrollbars=0');
windowIncsimHistRuns.moveTo(500, 300);
}

In the body of the popup window the following function tries to read the parent window name:

Code:
function SetDisplay() {
document.getElementById('<%=TextBoxSourcePageName.ClientID%>').value = window.parent.name;
}

In the page_load event of the popup window, I want to see what is value of TextBoxSourcePageName control. I hoped I will get 'MarketVal'. But I never get anything.

Code:
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
try
{
if (TextBoxSourcePageName.Text == "MarketVal")
}
}
}

C# - Wouldn't Read The Config File / Getting Error

Jan 3, 2010

Question: I have an annoying problem with nhibernate.The problem is I cannot get any example I find on the web to work... I've now tried for two days...

The first problem was it wouldn't read the config file, so I had to move it into app.config / web.config.

The second problem is that whatever I do, I always get an error:
No persister for: NHibernate.Examples.QuickStart.User

I've searched google and I did change the mapping to embeded ressource, and I did add the mapping to the config file, but nothing helps...

The example is from this page:
https://www.hibernate.org/362.html

I've uploaded my Visual Studio 2005 project to
