I have a server making a head request to a database dump I've created. The remote server does this to make sure that it's not using excessive bandwidth when not necessary.However, due to some other circumstances outside my control this causes the script to be hit twice: once for the head request, and then another time to download the data.

The remote server does this to make sure that it's not using excessive bandwidth when not necessary.However, due to some other circumstances outside my control this causes the script to be hit twice: once for the head request, and then another time to download the data.
What I'd like is to have the script I've written detect the head request, send back a couple of headers (e.g. last modified is right now, filesize different than before), and exit. Is there a way to do this?
while using HTTP web Requests, when i try and read the stream i always get an error saying 403 Forbidden but if i try to do it in the VB.Net web browser it works fine. Here is my code:
Imports System.Net
Imports System.Text
Imports System.IO
[Code]....
In VB.Net, how do I make a program to tap into the HTTP requests made by external web browsers? I don't want to edit or stop the headers, only 'read' them, i.e., access its contents. I'm speaking of something like Fiddler2, but I only want the 'reading' part. I also want to read the user-agent.

I heard i can use http request to vist websites ?
Im just using

I'm looking for some advice on how to optimise the following process:App reads csv file.For each line in the file an XML message is created Each XML message is posted to a URL via a HTTPWebRequest This process was designed to handle low volumes of messages (up to about 200 at a time), un suprisingly thinks have changed and it is now expected to handle up to about 3000 at a time.
The code used to post the message is here: Public Function PostXml(ByVal XML As String) As HttpStatusCode
[Code]...
I am currently restricted to sending multiple messages due to restrictions elsewhere in the system. There is a noticable delay in responding to the request at the other end (the receiver) but this is outside my control. I am trying to ensure that the process of sending is as efficient as possible (external factors notwithstanding).

can anyone show me samples or guide me to do a pop-up calendar after I click a button. The pop-up calendar is for the user to select their date of birth, so I would like it to customize the calendar also. And for my website I have master page, so I can't add javascript at the <head> section right?
View 6 RepliesI have a page that includes javascript which I only want to run under certain conditions. To do this I have placed the scripts into an asp: placeholder.This actually seems to work but when I run a debug on the page I get the following warning.Element 'placeholder' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.If I move the placeholders into the body of the page the warning goes, but that means I'm left with scripts in the body which I also want to avoid. Does anyone have any hints on the best practice for this scenario? [code]

View 1 RepliesI'm trying to use head.js in my master page, and unfortunately. I can't seem to get the syntax down as I need to use ResolveUrl. Here's what I have:
head.js("<%= ResolveUrl("~/js/jquery-1.4.2.min.js") %>","<%=
ResolveUrl("~/js/jquery.jstree.min.js") %>");
Any suggestions? This doesn't work. By "doesn't work", I mean that the head.js call doesn't recognize the quotations I'm using. It isn't loading the files basically because I have some sort of incorrect syntax that the VS 2010 isn't telling me.

View 12 RepliesObjects whose Properties are observed for changes must implement the System.ComponentModel.INotifyPropertyChanged event to alert their WPF-element observers that a change has occurred.
If I have a Visual Basic Module whose Properties I wish to have observed by a WPF element, how should I go about routing the Properties of that Module through to the WPF, considering that Modules cannot, themselves, implement Interfaces?

View 2 RepliesThe idea with System.IntPtr is to represent an integer whose width in bits correspond to the size of a pointer in the hardware and operating system that the CLR is running in, it's platform specific in other words. It supports 32-bit and 64-bit architectures only.This is a legacy from old-style C API's where pointers and ints were frequently treated as interchangeable. The Win32 API has many such parameters, where the width varies with the underlying architecture thus the mess with porting of code from 32-bit to 64-bit (we already did this once when going from 16-bit to 32-bit, funny how we never learn...).In practice, as is mentioned in other responses, it can be used to hold unmanaged resource handles and pointers etc that stem from the underlying Win32 functions. It can also be used to hold integers of the natural size for current platform. You can also use IntPtr.Size to dtermine the size of a pointer on the current platform.SO when you explain this to a child ;) this would be used to let program's flow at the same speed at diffrent kinds of operating systems?

View 3 RepliesI'm using VB.net to have a GUI on top of a commandline program.
[code]...
Which works and prints out all output from the commandline program. However at some point the commandline program ask for user interaction, eg: Type a number (1/2/3/4):But the commandline program stops after this. I suspect this is because it doesn't receive a valid option.Is there a way to capture when the commandline program wants user interaction and hold the reading of the stream to be able to enable the user to input something?

I have a class, BaseSample, that uses another class, MainData, as one of its fields:
Protected _sampleData As MainData
Public Property SampleData() As MainData
Get
[code]....
MainData in turn has a collection of a class, ProcessData, as a field and ProcessData has a collection of a class, Measurement, as a field. I.e.:
MainData
|- IEnumerable (Of ProcessData)
|- IEnumerable (Of Measurement)
These classes are entities in a LINQ to SQL file. In the Measurement class, I raise the PropertyChanged event when the CrucibleOxidizedMass property changes:
Private Sub OnCrucibleOxidizedMassChanged()
RaiseEvent PropertyChanged(Me, New ComponentModel.PropertyChangedEventArgs("CrucibleOxidizedMass"))
End Sub
In the BaseSample class, I want to respond to the CrucibleOxidizedMass PropertyChanged event in any of the descendent Measurment instances. How would I do this?
