VS 2008 Sending Data To A Webpage Via POST, Data Not Getting There
Jun 16, 2010
I've code this code below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim hwrRequest As HttpWebRequest = HttpWebRequest.Create("http://www.example.com/web-service.php")
[Code]....
The MsgBox() at the end shows the response, which as I've added to my script, echos the result from the $user and $pass variables which are supposed to retrieve those details being written to the stream above, but they show up empty.
I'm retrieving those values by doing: $user = $_POST["user"]; $pass = $_POST["pass"];
I wanna send POST data to the current web page viewed in my webbrowser. It's for logging into a page so the fields are "Username" and "Password". And then I might have to make it press the "Log in" button?
EDIT: It was easier than I thought when you don't need to do it silent in the background.
I need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.
For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data
I have the following code which I mashed up from several sources:[code]This works great until I add another POST parameters to query, like "client=mgdf&version=100".No errors are thrown, the program doesn't crash, nothing. It simply stops working. How can I POST multiple values to my server?
Now, i have a form which would usually post the text which should be writen, so, can this be done directly, without that form, using httpwebrequest in VB?
I am trying to post data to a multipart form. The problem right now is that I cannot determine the boundary of the data. The only way to find it is to actually POST some data (as far as I know). The boundary also changes each POST for a single static page.Is there a way to find the post data boundary?
I can grab info from a website uing httpwebrequest but i don't know how to post to a form :/Ive always used a webbrowser for this but its a tad slow.Here is what i use with a webbrowser:
Dim DBSplit() As String = Split(TextBox5.Text, "/") WebBrowser1.Document.GetElementById("email").SetAttribute("value", TextBox1.Text) WebBrowser1.Document.GetElementById("Pwd").SetAttribute("value", TextBox6.Text)
[code]....
How would i post this data to a form using httpwebrequest?
[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.
I've managed to narrow down my issue to a simple annoyance. I had a Webbrowser control mostly coded to navigate around an Oracle CRM On Demand site to generate metric reports, but then realized when I tried to build in the auto-download part, that the Webbrowser object wasn't going to give me the behind-the-scenes control I wanted. Searching online, it seems the Webclient control might be a better route. However I'm stuck trying to get by the login page so I can use the Download-File method to get my generated xls report. [Code] But every reply from the server has "Sign In Error: Both a user sign in ID and a password must be given." which tells me the form/post data isn't getting where it needs to go (It thinks the form is blank at [Code].
The above username and password are bogus of course, but once I can get a different reply then 'the fields are blank' I can worry about correct logon information. I'm just not sure what I'm not doing correctly or if I need to include something else. Since it's a publicly accessible site and I'm stuck getting something in the form to be 'seen', it should be easy for others to try and test.
I have a program that I collect data using a com port. I display that using special visual controls - no problem here.
What I would like to do is to send this same information out over the network via ethernet to another PC located in another room.
I presume I would have to have another copy of the program on the second pc as the information is simply duplicated but I am not sure how to get the data out of one to the other
I am having trouble sending data to a comport..... I am a noob at this and have been doing my head in... I have done a fair bit to a few programs that I have on the go, but am stuck at sending some data to the comport...
I have in form1 put the serial port contol and added SerialPort1.Open() to that. I have then added 3 buttons that I was to use to send data to the port... Since this is for a radio scanner the buttons turn the backlight on / dim and off.....
LTN is used to turn the light on and works fine in hyperterminal.. I have got the port settings right in vs2008 but the code is wrong.
I have:
code:
Then I get warning of Name 'LTN' is not declared...
I wanted to create an event that when I hit a button, it will check if the webbrowser has reached THISPAGE.html.
If webbrower1.Url.toString = "thispage.html" then 'this line may have been webbrowser.Url.toString("thispage.html") cant remember I tried both ways neither worked. do something End If But I get a null exception error.
My other question is , is it possible to pull data or text from a website like through the webbrowser control thing and place it inside a textbox or label or something like that?
I am trying to pull wind direction, temperature and speed, data from this webpage, I have had not much success with it at all, I think that I have the correct method but get stuck on the HTML coding. the webpage is: [URL] I sort of know how to get to the HTML code, but get lost on how to define the ellements that are required. I have a screen capture of where I get up to.
Imagine a project with couple of forms and a module. Now as per my knowledge if i want to send some data from one form to another then :
- If I declare variable friend/public in a module then it can be accessed in the entire project (thus also between forms). - If I just have to send data from one form to another, then I can call the other form's sub/function and pass value. - If the pass value by reference then I can get new value only if its changed in that function.
Now what the issue is, I need to pass a variable to a form and in that form when user types contents in a textbox or makes other selection and presses OK button then it should return some values back to the calling form. Now how can I achieve this (without declaring global variables which will be accessible everywhere) ?
I have a very basic knowledge of coding, just enough to understand some PicBASIC Pro and program a microchip to send the values of some variables to a PC via the com port. I've used a terminal utility like Hyperterm to confirm the right variables are being sent, so I thought it would be cool to have a custom application on the PC to display these variables, and possible set them via the application by writing the new one back to the PIC. So I downloaded VB express 2008 - and whilst it was "simple" to draw a box and add a few text boxes I'm lost at how to actually do anything practical with it
[Code]...
Could someone advise me in laymens terms exactly what I need to do inorder to populate the text boxes with the data from the PIC micro. Whilst I understand the basics about BASIC, I have no idea on things like classes etc
auto filling data into webpages. I need to write a server side application mostly a console host app that makes some queries to the SQL Server database and gets a list of lets say students and their grades.There is a third party website that gets updated at the moment some peoples working and filling that data manually.
I need to write a program that will basically open that webpage, login if required, navigate to certain page, click on certain tab, fill the data and hit the submit button. I don't think this part is that hard but the trouble comes with a client side dialog box. At the moment there is a client side dialogbox that shows up when you hit the submit button confirming the action and I need to press OK on that automatically.
I am allowed to write a windows application if not a console application and also use the web browser control to load the webpage rather than opening and interacting with the browser. If this makes it easier than so be it.
I have a form that loads a UserControl which has a tabpage. Each tab has textboxes that I need to update when I create the tab page. I actually had this working but lost a major version of the code and can not remember how I did it. I want to send data to usercontrol this way from the form Do While
count <= intGrpSize With TabCtrlClient() .TabPages.Add(New TabPageEx) UC.SetSessionDate(tbSessionDate.Text) uc.SetCouncelor(CInt(cbProviderID.Text))
I'm not sure what I have done wrong, I am trying to get my program to send data (UsernamesPasswords) from client to server, then the server says if it's right or wrong.
The error is on this line: Dim networkStream As NetworkStream = TcpClient.GetStream()
Heres the Client: Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click If TextBox1.Text = "" Then MsgBox("You must enter UN/PW!") [Code] .....
I wanted to ask you something which is bugging me for a while. I work an IT dept at a local bank and I got instructions to make an application which should retrieve some financial info from a financial banking stats page.
The webpage can be accessed through [URL].. and the info can be seen in the web browser but I cannot extract them because the info is not available in the source code of the page.It seems it's generating the info dynamically using a jsquery.js file.
I was wondering if it's possible to make an app which uses some cache or something (I guess the the page is saved temporary somewhere on the disk for the current session) to retrieve that data in vb.net?
My program so far reads a certain webpage's source code and places it in a textbox. This much has already been accomplished.
Now I need to pick certain strings out of the rather large amount of text data and have the lines stored in variables, but the trick of it is, the exact string is unknown. The exact function should be, that the code finds certain tags from the source code, say <td> and </td> and takes the string data in between those tags, what ever it may be.
I am creating that will use Post Data instead of a web browser. I am new to post and this is my first time using it. I decided to go with something easy, and just make a program to auto login to Facebook. When I try it out it doesn't log me in. There are no errors or anything, just doesn't work. My code is below if anyone wouldn't mind checking it out to see what is wrong.
I have a Customer JSON object created which has value as below:[code]I need to get this data in the Handlers/CustomerHandler.ashx to do some DB operations.[code]
I'm currently working on web application using VB in ASP.NET.Right now I have 1 page with panels that we are using to show/hide depending on the flow. When the user first comes in, he/she is presented with a gridview containing a list of clients. Then the user, clicks a link from a row and is presented a form where he/she can update the clients' info.Originally, I had a HYPERLINKFIELD that put the clientId in the url, then I'd grab the url and do the code appropriately
There is a system that needs to POST data to my site and all they asked for is for me to provide them with a URL. So I gave them my URL [URL]
Now I do not know exactly how they POST it but now on my Test.aspx page I need to write code that will save that data to a database.
But how would this work and what must I do on my Test.aspx page?
I wrote some code in my Page Load Event that sends me an email on Page Load to see if they actually hit the page and it does not seem like they are even?
Is there a way to intercept POST data like HTTPAnalyzer?Can I make a call to send the data, see how it's formatted but actually block the connection if I know where it's coming from? My goal here is to replicate the sending of an email through an SMTP server.
How to post data in HTTPS authorization in .NET?How to get headers(cookies), get html code and set headers(cookies) in HTTPS?
