ASP.NET: Httpwebrequest Date Header Workaround?
Jul 16, 2009
I'm trying to integrate with an API that requires the "Date" header in a web request. As you may well know, .NET has removed the ability to append or even display a default Date header in your request, so I was wondering about a workaround.Here's the catch: you can't use TCPClients because I don't have "permissions" on my server for such a thing as sockets. Is there some way to "cheat" the system to fake a date header or to trick it into posting a Date header? Or should I just give up on this API?

I have a report based on a query which requires the user to input the date range. I would like this date range to be a label in the report header. Which shows both the date and time an entry was made. For the previous reports I would run Yearly reports Display the Day ,month and year entered in a parameter query. At present I am trying to run a report for the period "Jan 1 2010 to Dec 31 2010" and would like a formula that would display "Jan 1 2010 to Dec 31 2010" in the report header.
SELECT GetAutonumber([CountryName]) AS [No], ProjectDetails.ProjectName,
FundingInstitution.FundingInstitution, EOIDetails.ClientAddress,
EOIDetails.DateOfSubmission, EOIDetails.ConsortiumName,

I am coding a VB.NET application which heavily deals with a collection type. See the code below:
[Code]....
I have to type the above line for so many times. If I changed the collection type, then I have to make the change for all the instances. So if there is a way to use "a typedef equivalent", then I can get rid of all these problems. I tried with imports, but it is only for namespaces and it can't be used for classes.
Note: I am using VB 2008, windows XP. The application type is windows forms(VB). EDIT: I made some tries based on code_gray's below answer. This is the first try.

I have a legacy COM-component with an interface declaring a property like this (IDL notation):
[Code]...
This interface is implemented in a calling application written in VB6 like this:
[Code]...
Everyting works fine until I try to do the same in VB.Net. VB.Net refuses to compile code where a parameter of a property is passed ByRef. MSDN says VB.Net doesn't allow such parameters. Is there any way I could implement such a property in VB.Net?

I'm using the following code to populate a DataGridView with a worksheet. This is working fine, however, I'm unsure how I can get the Text from the page header. (not to be confused with the column header). Later in my code when I am exporting into an existing workbook with a new worksheet, I'm wanting to use the header text as the tab name. The header text being "September 2009" so that when I import/manipulate/export october, the new tab will be "October 2009" etc. [Code]

I know that there is no DESIGN, DESIGN_MODE, DESIGN_TIME, etc preprocessor directive value. However, I need something that can do the trick. I can't use a normal If statement, because in my case I need to change the inherited class so that the control renders properly at design time. If not, I'll receive an exception due to the fact that the inherited class is an abstract class.Here's what I'm looking to accomplish:
Partial Class MyCustomControl
#If DesignMode Then
Inherits UserControl
#Else
Inherits WidgetControl
#End If

I'm downloading a bunch of files from a URI but when they get big, I get an utOfMemoryException. I thought at first it was MemoryStream error but I'm pretty sure now that the error is rooted in the declaration of an array of Bytes that's too large. (Half a gig is fine, 1.7 gig is not.)

what's a Class, and Object, a Method, a property and thins like that, but I have this doubt:Let's supppose I have a class "Laundry" this class has (just for this example) 3 propierties:
1.- laundryID
2.- Name
3.- Washers
Id and Name are "primitive" types or simple types (integer and string), but Washers, represent a list of object of type "Washer", that has 3 properties:
1.- washerID
2.- laundryID
3.- capacity
4.- brand
All of them (for this example) simple/primitives types (integer,string,string).So this my dilemma, it is correct to have a constructor like this (VB .net)
public sub new(ByVal laundryID as integer)
'' Here I'll query for the data of the Laundry on DB
'' After that I will query for every washer that belongs to this laundry
[code]....
And inside of that constructor query for all the washers that belongs to the laundry with id=laundryID parameter, and create objects of type "Washer" and add them to the list of Laundry ?I'm not sure If I explain myself, any comment I'll be really grateful, in less words, what's the correct approach (or good practices) to work with class/objects that has properties which are complex (other class/objects).I usually work with ADO.net probably ADO/LINQ/Entity solve this thins in an transparent way, but if they do it I don't really know it.
Note: I'm familiar with VB.net, C#, PHP, so if you prefer explain/help me using examples with its syntax, it's ok

It's kinda overkill (i7, 8GB, SDD, W7 x64) for what I actually need but it is supposed to last for a few years.For maintenance issues I had to install Visual Studio 2005 and it turns out that "Edit and Continue" wasn't working . I found a thread here HTML Code:[URL] in which I read that E&C is not supported in 64-bit OS.

I'm trying to make a label transparent. When I set the BackColor to transparent, all it does it take the color of the form it's sitting on, i.e. It's not truly transparent. I've googled it and found this in another thread (from a MSFT MVP)".NET controls do not support true transparency. You can set their BackColor to Transparent (in some but not all cases) and the parent control will show through, but only the parent control. If there is some other control behind that is not the parent it will not show through. That's because the control is not truly transparent. It basically copies its parent in the area behind it and uses that as its background, but that doesn't include sibling controls that may be behind it as well." To me, this is completely unacceptable. Why even include the transparency option when all it does is set the control's backcolor to the form color? I'm trying to add a label over a progress bar to give my user some feedback (because the Visual Studio progress bar doesn't support text, which is also a horrible design shortfall by the way), and have yet to find a way around this.

I am facing a strange problem with listbox. I need to scrab whois information. I used the following code to get source code of the whois query. It works fine if I use a textbox. But I need to use this for multiple url and therefore need to use lixtbox to loop through url list. Unfortunately when I use listbox1.selecteditem or listbox1.text it does not work. But this same code works with webbrowser.
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("http://www.networksolutions.com/whois/results.jsp?domain=" & listbox1.selecteditem)
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705)"

I'm building this class to download files in parts/sections/segments. In .NET 4.0, I can use this code to specify the range to download from
long startPos = int.MaxValue+1;
HttpWebRequest.AddRange(startPos);
and it works because there is a long overload for the AddRange method. When I looked up the .NET 3.5 version, I realised the AddRange() method allows using int only. The possible workaround would be using the AddRange(string, int) or AddRange(string, int, int) methods. Since the class will have to work in .NET 3.5, I'll have to go with the string specification but unfortunately I can't seem to find any sample code that shows how to specify ranges using this procedure in .NET 3.5. Can anyone show be how to do this?As the first code sample I wrote shows, I would like to specify a range of type long instead of int. Using type int allows requesting for byte ranges only up to 2GB but long allows requesting for byte ranges beyong 2GB.
The question therefore is: How do I specify byte ranges of 2GB or higher on HttpWebRequest in .NET 3.5?

dim objrequest as httpwebrequest
dim objresponse as httpwebresponse
Try
[Code]...
My problem is: for some url that function takes a long time. So, i just want to cancel the response after a given time. I tried with a timer control but that is not working. What to do? How to modify this code so this function will return result within a given time whether httpwebresponse completed or not?

how to write a httpwebrequest, however i'm unsure of how to write it with a if...statement. I have a file that I need to download, however it ususally doesn't get posted until sometime Tuesday afternoon, so what I need to do is have the program continually check say once about every 5 minutes until the file has been posted and then download it.I'm presumming using an if...statement is the best way to accomplish this, basically if true(file exists) then proceed, else wait 5 minutes and rerun process.

use a If then Statement with Httpwebrequest? Let me explain my senario. I have a file that needs to be downloaded from a web site once it is posted. Currently one of our staff manually goes out to the web site multiple times to check to see if the file has been posted, they then download the file, extract it's contents and use some of the info for reports that must be sent out the same day.
