Uhm, that's really unclear. What do you mean by 'Internet Explorer Web Page'? IE, like all browsers, can display any of zillions of web pages. Do you mean you want to be able to parse the HTML that comprises a given page, or what?

i want to pick data from text boxes and labels on a web page. the web page can be of any web site. For exampla, there is log in page of a site, it has a text box to key in the username, i want to pick that value thru code.

Ah. Well, I think you're going to find this harder than you might expect. Those buttons, text boxes, combo boxes, and other such things are generally part of 'web forms'. The user can fill them in, and then when they are done, they let their browser know (typically by clicking a 'submit' button, or something similar) that they wish to send the data to the server (usually, though it can also be processed by client-side scripts) for processing.

The trick is, the destination is coded as part of the web page. When the user submits the form, the browser submits it to the appropriate party, generally the server where the page is located. It can send the data as part of the URL, or as part of the request header (or whatever it's called; HTTP isn't my forte). The remote end accesses this information in different ways, depending on a) the server in question, and b) the method used to process requests. For example, ASP might access these values by reading properties, whereas for CGI, you might read them by getting environment variables. You won't be able to do it client-side without using client-side scripting (like Javascript), and even then, you'd need to rewrite the HTML to do this.

Thanks for the prompt reply but i was not looking for what you have told. Let me explain what i want to do via an example. Lets say there is a web form that has been filled by a user. the submit button has not been clicked yet and the data can be visibly seen at the moment. Using a VB code, i want to pick up that data in the respective fields with their labels text. If this is possible, plz reply back with the answer asap.

Thanks.

You might want to read up on 'shatter attacks' in Windows. These exploit the Win32 message system, whereby you can send messages to various windows (including edit boxes, buttons, etc), even if those windows are owned by a process other than yours. By exploiting this, you can compromise Windows. How does this help you? Well, this page explains how to get the handles for these other windows, and you can then use Windows messages and/or functions to query them as to their window text.

Not all of us check the forums every single hour. I know it's hard to believe, but most of us do have lives.

As lectricpharoah said, you'll need to use the Win32 messaging subsystem. To do this in Visual Basic, you'll need to use functions that are not available by default. To use them, you'll need to tell VB how to access these functions. Finding out the code is pretty difficult work, so the nice people at ActiveVB made ApiViewer, which should help muchly.

This may be what you said.. but couldln't you enumerate all the windows that are currently open and then check each window's class to see if it matches with the internet explorer class then if it mathes run another enumeration of all the child windows (I'm pretty sure text boxes count as child windows... though I'm not positive) then get the value of all the text boxes? You may need to do a little bit more filtering but I think you could pretyt much do what your asking with that...
