Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Help getting information from a page.

    I have seen the GetElementById activex dialog, but these fields don't have identifiers. Is there a way that I could use Album:, Artist: and Song: to collect these values and insert them into a table from an embedded web browser on a form?

    The html source:
    HTML Code:
    <table align="center" width="80%" border="2" bgcolor="#FFFFFF"
    		bordercolor="#000080" cellspacing="0" cellpadding="0">
    		
    			<tr>
    				<td width="30%" height="0" align="RIGHT" bordercolor="#FFFFFF"><strong><font
    					face="Arial" size="-1" color="663300"><A
    					href="album/sublist_misc.htm#album" target="_blank">Album:</font></strong></td>
    				<td align="left" bordercolor="#FFFFFF">&nbsp; <font face="arial"
    					size=" -1"> One Of These Nights</font></td>
    			</tr>
    			<tr>
    				<td width="30%" align="RIGHT" bordercolor="#FFFFFF"><strong><font
    					face="Arial" size="-1" color="663300"><A
    					href="artist/sub_listmisc.htm#artist" target="_blank">Artist:</A></font></strong></td>
    				<td align="left" bordercolor="#FFFFFF">&nbsp; <font face="arial"
    					size=" -1"> Eagles</font></td>
    			</tr>
    			<tr>
    				<td width="30%" align="RIGHT" bordercolor="#FFFFFF"><strong><font
    					face="Arial" size="-1" color="663300"><A
    					href="song/sub_listmisc.htm#song" target="_blank">Song:</A></font></strong></td>
    				<td align="left" bordercolor="#FFFFFF">&nbsp; <font face="arial"
    					size=" -1"> After The Thrill Is Gone</font></td>
    			</tr>
    </table>
    Any help would be greatly appriciated.

    Use http_get_page2(), extract_string(), and stringscanner functions to get what you want.

    It takes a little playing around the get the right combination, but is very doable.

      Re: Help getting information from a page.

      Are there any articles or examples that might help me accomplish this. Between the three functions and the help files I am not sure where to start. Sorry for being such a noob.

          The activex routine is useful when the web page has div and id's in it.

          What Aaron is looking for requires a more 'brute force' method.

          Aaron

          I've given all that I've written about this (not much)... The 3 functions to use to get it done.

          This is really a create exercise to learn xbasic and programming with xbasic.

          Start with:

          Code:
          dim mywp as C
          mywp = http_get_page2(<url of the web page>)
          
          a5_show_variable(mywp)
          From there you have the entire page's HTML in the string variable mywp and you can break it apart from there...

            Re: Help getting information from a page.

            Code:
            size=" -1"> One Of These Nights</font></td>
            size=" -1"> Eagles</font></td>
            size=" -1"> After The Thrill Is Gone</font></td>
            Since these lines remain the same, on each line would it be possible to use the size=" -1"> and the </font></td> as a sort of delimiter to pull the information out of the displayed variable if the lines that these values appear on always remain the same?

              Check out the function.........

              Code:
              Sub_String as C = EXTRACT_STRING( Search_in_String as C, Start_Find as C, End_Find as C [, Occurrences as N [, Include_Tags as L [, Case_Sensitive as L [, Regex_Safe as L ]]]] )
              There can be only one.

                Al,
                your right, but his original question referenced a web browser on a form.
                Thats what I responded to. I use the technique you cite often in searching blogs for information.

                  I read it as Aaron had seen the example of the activex dialog, but that it referenced the div and ids and the web page that he wanted to read didn't have them.

                  Perhaps I missed read the original post. But that's what I see after reading it again.

                  Hope Aaron got his job done and working properly..
