[code] I'm trying to post data on these two TextBoxes using HttpWebRequest method , Blow is the post data string [code] So when i send this request to the website , It only post the password but not the name , There's something causing conflict with the word name either 'name="name"' this line or something else.
View 26 RepliesI have a program that will register you for a certain website using textboxes and stuff but I have an invisible web browser and it just enters the text into the right spots and clicks the button.I was told that I can get rid of the web browser and do the whole thing faster and easier using "HttpWebRequest and HttpWebResponse".
View 2 RepliesI'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

This is the short instruction:
1) Make a single HTTP-POST request to the following URL in XML format.
[URL]={password}&user={username}
2) The xml form field that is posted should be named "createorder".
I don't get the last part with naming the xml form field. What the xml form field means (stands for) in this context?

How would i post this data to a form using httpwebrequest?
At the moment im pulling the xml down and writing it to a file. Im then reading this file with an xmltextreader and displaying the data.
The problem i have is that i dont seem to be able to figure out how to do something similar to "getelementbyid("name")"
I am having to list all the elements for the reader in order, and cant seem to skip to a particular one, this is quite a large xml chunk, and if possible id like to skip bits out i dont need, or need yet.[code]...
I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).
View 7 RepliesI have a problem when trying to send a POST request. The sending method looks like this:
Public Sub SendXML(ByVal file As String)
Dim reader As New StreamReader(file)
Dim data As String = reader.ReadToEnd()
[Code]....
Now looking at this I suspected that it was due to the fact that the server does not accept POST messages. But some other reading suggests that the the URI [URL] has been generated with a proxy and should be /Request so the line should read POST /Request HTTP/1.1
So what would be the common reason for this? And if it is a proxy problem, how is it sorted?
As asked below, I have created a new question for the more specific request. Changing absolute URI to relative in HTTP POST header

I am using VB 2005 professional and SQL Server 2005 express edition.
For the last two weeks I have been trying to have a datagridview control on a form that will have datasource from a dataset with two tables that are related. I want child the column to be a ComboBoxColumn where userts can select options and update the other data(from the other table).
I have two tables in an sql server 2005 database named computers:-
computers
locations
Table computers looks like thisID is the primary key column)
ID Location
Computer139
Computer240
[Code].....
With the location column being a ComboBoxColumn so that when a user enters a new ID say Computer5,they have a choice of a dropdownmenu for the Location column. In the database table computers the item should be saved as well as the index value(to correspond to the LocationID).
I need some clarification. I'm planning to make a Scheduler program where it will fetch data from a MS Access Database, and I also want it to upload the data to a web server (MySQL Database) in JSON Format.
In the first process which is the fetching, I'll use System.Data.Ole.db namespace. This namespace mostly worked in MS Access. In the 2nd process which is the uploading, I am planning to use FTP protocol and should be JSON Format.
I was just confused with the second step, is FTP protocol applicable for this process?
I will make an Android apps to view all the data that will be saved on the web server.
