HttpWebResponse Not Receiving Anything
Jun 5, 2010I am having trouble with receiving bytes using HttpWebResponse.I can receive them just fine with WebClient, which I believe is just a wrapper for HttpWebResponse.Anyway, I put together some example code to re-create the situation. [code] If you just paste it into a empty Form1 and hit F5, it will create all controls automatically.I would use WebClient, but I want to get one byte at a time so I can have a detailed progress indicator, and I couldn't find any way to do that with WebClient.WebClient SendDataAsync has some serious problems where it only fires its progress update events like 3 times.Also, you will see if you press the button, it takes like 20 seconds of doing absolutely nothing, and then all of a sudden it downloads all the data in like a split second.If you press the button again and again, it only takes a split second.But the first time you push it, it takes for ever.Does anyone know why and how to fix that? [code] for the sake of all that is good and holy, don't use ACCESS, EXCEL, or a TEXT FILE as a database.If you want your program to use a "local database", without any of the hassle of setting up a MS SQL or MySQL server, just click this link: >>> SQLite <<<

HttpWebRequest.GetResponse And HttpWebResponse Freezes?
Sep 20, 2011I'm currently working on making a database driven app without using SQL and instead using a simplistic web directory to store information.Unfortunately after just beginning I hit a rock wall on creating a login screen. As it works right now, every user has a directory and within that directory is file called "access" which has a password. While I'm aware that's it not secure, that's later to come, but right now I'd just like it to work. But the program uses WebRequest to see whether or not there is a directory under the given username, if there is then the username is considered valid and it moves on to check the password- where I start to have trouble. The password verification uses WebRequest and WebResponse as well, using StreamReader to read the access file. At the moment, the password checker only works once in a single program instance. Otherwise trying to check another login will cause the program to hang or freeze when declaring the WebResponse variable (resp).
This is the password verification code (with URL's removed):
Dim Username As String = My.Settings.usrUsername'The function is in a BackgroundWorker so I use My.Settings to communicate with the UI.
Dim Password As String
Dim usrPassword As String = My.Settings.usrPassword

Httpwebresponse - Use WebRequest To Check If URI Is Valid?
May 27, 2010Looking for the best way to determine if a URI exists in VB.NET without downloading the actual content. System.IO.FileExists/My.Computer.FileSystem.FileExists can be used locally to determine if a file exists, is there an equivalent for the Web?
Currently I am using a HttpWebRequest to check URI existance using the ResponseStream. This populates the stream if the target does exist and throws an exception if it doesn't. The function is being expanded to also check for PDF files (typically 5MB +), images, etc and it will be a waste of time/bandwidth to actually populate the content into a stream.
In the case of "Success" (the target does exist) I do not wish to download the file or page, simply to end up with a Boolean which indicates the whether something exists at the end of this URI.
Httpwebresponse = Request.getresponse Freezes?
Dec 13, 2010I tried using suggestions from other posts for this and still no resolution. When sending a POST request, at times it will just begin to freeze and stall. I set up my code as follows and now basically if I cannot figure out why it is freezing, then itneeds to timeout, handle the exception and restart the function.
For i As Integer = 0 To searchItems.Count - 1
If uri.Scheme = uri.UriSchemeHttps Then
Dim request As HttpWebRequest = HttpWebRequest.Create(url)

What I come to know through googling, is one way to add <base href="target webpage url"> tag in <head> section of resultant strings received through httpwebresponse and the display the modified result. For this purpose someone suggested me using Html Agility Pack.

How To Break Up String Of Key Value Pairs
Jul 23, 2009I have a variable that reads in a POST from paypal. This is the instant payment notification stream and all the keys and values are stored into a string variable .
mc_gross=0.05&protection_eligibility=Ineligible&payer_id=UEWAFF732VL&tax=0.00&payment_date=22%3A36%3A55+Jul+21%2C+2009+PDT&payment_status=Completed&charset=windows-1252&first_name=Scot
This is part of the string. How do I break this up into a set of variables. I tried using request.form but this did not do anything. I'm trying to get the variables and then pass them to a function that will write everything to a database.
Dim amount = Request.Form("mc_gross")
Dim currency = Request.Form("currency")
Dim pmtdate = Request.Form("payment_date")
Dim status = Request.Form("payment_status")
I only need certain variables from this variable which is strNewvalue. How to I get the values stored in this variable?

Use SortedDictionary To Store 65,000 Keyvalue Pairs?
May 17, 2012I'm thinking to use the SortedDictionary to store 65,000 set of keypairs and from time to time during my program execution, I need to retrieve the value from the this dictionary. May i know will there any concern especially in term of speed of execution if i use this method as above? Is there max. capacity that a dictionary can hold?
Previously, i was thinking to use a simple 2D array to do this, but it mights slow things down because in order to retrieve the value, i might need to loop through the whole array till i found the value that i want.

View 3 RepliesVS 2010 Creating A Game Of Pairs As A Project
Apr 26, 2012I'm having a little trouble creating a game of pairs as a project.Basically I've got to the point where I can start a game, layout a bunch of cards in a grid, 6x6, and then have a way of matching the pairs together. First of all I used a For loop to assign the cards into a two dimensional array. They are pictureboxes however so when a user clicks on 2 cards, checking them to see if they match has become confusing. I've tried to stuff like this for example but it's not working: [code] This doesn't work because it can't compare the picture boxes stored to the array slot. Is there any clever person with a way around this? Or that can think of a way to compare them. The pictureboxes kinda need to stay like there though :/

View 1 RepliesAutogenerate/compile Code On-the-fly At Runtime Based Upon Values (like Key/value Pairs) Parsed Out Of A Configuration File?
Jan 2, 2011I have a set of classes that mimics enums (see my other questions for specific details/examples). For 90% of my project, I can compile everything in at design time. But the remaining 10% is going to need to be editable w/o re-compiling the project in VS 2010. This remaining 10% will be based on a templated version of my Enums class, but will generate code at runtime, based upon data values sourced in from external configuration files.what my Enums class looks like. The templated fields, per that question, will be the MaxEnums Int32, Names String() array, and Values array, plus each shared implementation of the Enums sub-class (which themselves, represent the Enums that I use elsewhere in my code).I'd like to parse values from a simple text file (INI-style) of key/value pairs:
[Section1]
Enum1=enum_one
Enum2=enum_two
Enum3=enum_three
So that the following code would be generated (and compiled) at runtime (comments/supporting code stripped to reduce question size):
Friend Shared ReadOnly MaxEnums As Int32 = 3
Private Shared ReadOnly _Names As String() = New String() _
{"enum_one", "enum_two", "enum_three"}
[code]....
I'm certain this would need to be generated in MSIL code, and I know from reading that the two components to look at are CodeDom and Reflection.Emit, but I was wondering if anyone had working examples (or pointers to working examples) versus really long articles. I'm a hands-on learner, so I have to have example code to play with.
