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.

Variable is of different type

  • Variable is of different type

    I am getting errors in regard to data types and hopefully someone can see why. I have 2 tables (noted below) both with the field Transaction_no and both designating it as numeric.

    Error 1
    When I run the below code I get "Variable is of different type"" for the dim transaction_no as n line

    Code:
    <%a5
    '? "Transaction"+session.transaction + "<br>"
    '? "Session User Name"+session.User_Name+  "<br>"
    '? "Session User Id" +session.USer_Id + "<br>"
    'end
    
    dim tbl_dest as p
    dim tbl_from as p
    dim myindex as p
    dim transaction_no as n
    dim From_User_id as c
    
    Transaction_no=session.transaction
    From_User_Id=session.User_Id
    
    '?transaction_no
    '?From_User_id
    'end
    
    tbl_from = table.open("[PathAlias.ADB_Path]\swap_transactions.dbf",FILE_RW_SHARED)
    tbl_dest = table.open("[PathAlias.ADB_Path]\feedback.dbf",FILE_RW_SHARED)
    myindex1 = tbl_dest.index_primary_put("Transaction_no")
    
    tbl_dest.fetch_find(transaction_no)
    tbl_from.fetch_find(transaction_no)

    Error 2

    When I change that dim statement to 'c' I then get;

    Error:Script: /Feedback.a5w line:38
    tbl_dest.fetch_find("transaction_no")
    Conflicting expression data types


    Which makes sense to me. I truly don't understand why I get Error 1.

    Any insight?

    Re: Variable is of different type

    session vars are always charactor values. Use this:

    Transaction_no=convert_type(session.transaction,"n")

      Re: Variable is of different type

      Thanks for the clarification-

      I added that line right after;

      "Transaction_no=session.transaction"

      to convert it but got the above Error 2 again.

      Script Error
      Error:Script: /Feedback.a5w line:40
      tbl_dest.fetch_find(transaction_no)
      Conflicting expression data types


      Am I putting it in the right place?

        Ken,

        i think you want to use the conversion instead of the equality. So instead of putting it after the "Transaction_no=session.transaction" statement, use it instead of the statement.

            hi Ken

            i think that you have a simple naming problem here

            dim transaction_no as n


            tbl_from = table.open("[PathAlias.ADB_Path]\swap_transactions.dbf",FILE_RW_SHARED)
            tbl_dest = table.open("[PathAlias.ADB_Path]\swap_transactions.dbf",FILE_RW_SHARED)
            myindex1 = tbl_dest.index_primary_put("Transaction_no")


            i'll bet dollars to donuts that the actual field in the tables
            swap_transactions.dbf and feedback.dbf is also named transaction_no

            if thats the case then you have actually tried to use the same variable twice
            a big no-no
            you are trying to confuse Alpha5 and its not having any of that
            you should try to use a nameing convention that would avoid this

            i would do something like

            dim mytnumber as N
            mytnumber = session.transaction

            then use this variable for the find operation

            tbl_dest.fetch_find(mytnumber)
            tbl_from.fetch_find(mytnumber)


            also unless you have a typo
            you dimmed
            dim myindex as p
            but used
            myindex1 = tbl_dest.index_primary_put("Transaction_no")
            for the find operation

            you also might need to set the index pointer for the second table also
            dim myindex2 as P
            myindex2 = tbl_from.index_primary_put("Transaction_no")
            tbl_from.fetch_find(mytnumber)


            hth
            regards
