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.

    .AddSheetFromResultSet generates an exception

    Code:
    dim result as p
    result=http_get("https:......................")
    dim Doc as Office::Excel2003Document
    Doc.Load("C:\Users\..............\xyz.xls")
    doc.AddSheetFromResultSet(result,"sheet1",.t.)
    Doc.Save("C:\Users\..............\xyz.xls")
    delete Doc

    Why?

    Probably already has a sheet1.
    There can be only one.

        Re: .AddSheetFromResultSet generates an exception

        May be a problem with whatever is being returned by result=http_get("https:......................").

        doc.AddSheetFromResultSet(result,"sheet1",.t.) 'result is supposed to be a SQL resultset derived something like

        Code:
        dim conn as SQL::Connection
        dim rs as SQL::ResultSet
        dim connString as C
        dim select_exp as C
        connString = "{A5API='Access', FileName='c:\program files\a5v8\mdbfiles\alphasports.mdb'}"
        select_exp = "select * from customer where bill_state_region = 'ny'"
        if .not. conn.open(connString)
            ui_msg_box("Error", conn.CallResult.text)
            end
        end if
        if .not. conn.execute(select_exp)
            ui_msg_box("Error", conn.CallResult.text)
            conn.close()
            end
        end if
        rs = conn.ResultSet
        conn.close()
        No error when I used such a resultset and specified sheet7 for a test.
        There can be only one.

          The URL has a spreadsheet published online which is returned as a blob.
          The interesting thing is if I take that blob and paste it to an Excel spreadsheet, Excel parses the blob into a spreadsheet flawlessly.
          The trouble is trying to parse that blob in alpha.

            dim result as p
            result=http_get("https:......................")
            since you are using http_get, it is returning a pointer, but actually the result.body is the data.
            may be you could try,
            Code:
            dim Doc as Office::Excel2003Document
            Doc.Load("C:\Users\..............\xyz.xls")
            doc.AddSheetFromResultSet(result.body,"sheet1",.t.)
            Doc.Save("C:\Users\..............\xyz.xls")
            delete Doc

              Re: .AddSheetFromResultSet generates an exception

              You are correct, it's a pointer with http_get() and a blob with http_get_page2().
              I have been working with all of them,
              Anyway, this is part of a project and I figured an easier more straight forward way to get it in alpha and abandoned this approach altogether. Thanks

                Re: .AddSheetFromResultSet generates an exception

                This is part of a mini project to get data from spreadsheet from a web page directly into an alpha table.
                It would have been nice if I would have been able to take the blob (either from response.body or directly from http_get_page2()) and parse it directly in alpha. But that did not work. Not sure why. Could be a version issue.

                So, I resorted to using Excel as an intermediary.
                I tried multiple different ways in Excel with success. Now I am just trying to find the most efficient way. So if anyone has some ideas, please let me know. Or, if I manage somehow to parse the blob directly into the table, that would be best.

                But using Excel comes with a lot of nuances, as the documentation on the subject is sparse and repeatedly states that "Excel does not like this, or Excel does not like that..".
                I should perhaps, time permitting, start a new thread on the subject, having noticed multiple quirks when using pointers to Excel.

                Some of the difficulties I am running into with Excel might have to do with the alpha version I am using. V11 (can't remember the build). That might be part of it. With my time being so limited right now, I couldn't spend much time debugging it. But I will provide examples in a separate thread to see if it's a version issue or something else.
                Thanks

                  Re: .AddSheetFromResultSet generates an exception

                  i am not proficient in desktop side but here is something i tried seems so far so good,
                  i used http_download function to download the xls file to c:\temp directory and then used operation to import data into a dbf table with the names. all worked good.
                  can this be done in coded version, i do not know yet.
                  you probably can you know way better than i.
                  thanks for reading

                    That's one of the ways I already tried using Excel and it worked just fine.
