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.

    how to open a browse with no records from a form

    I am trying to add records to a browse that do not have matching records yet from a form.
    When I press the button to open the browse, I get the error "no records in query". If there are records matching, it will open and I can add more records to the browse.
    How can I open the browse with that error? In other words, when there are no records yet.

    I think we could add or delete a line in the following code to force it.
    Is it possible?

    Code:
    dim flag_error as l
    flag_error = .f.
    if is_object(topparent.this) then 
     p = topparent.this
     
     if eval_valid("P:Id.value") then 
      DELETE Parameter1 
      'Set the Parameter variable to the object's .value property
      Parameter1 = eval("P:Id.value")
     else
      flag_error = .t.
     end if 
    else
     flag_error = .t.
    end if 
    if flag_error then 
     ui_msg_box("Error","Id does not exist. This script cannot be run in this context.",UI_STOP_SYMBOL)
     end 
    end if 
    
    filter = "idmatch = [varC->parameter1]"
    query.filter = replace_parameters(filter,local_variables())
    query.order = ""
    
    'Open the layout_type showing just the records that satisfy the filter
    DIM Shared varP_Rembrowse as P
    DIM layout_name as c 
    layout_name = "Rembrowse"
    
    dim tempP as p
    'Get pointer to existing window. In case layout_name is qualified with a dictionary name, extract up to first @. In case formname has spaces, normalize it
    tempP=obj(":"+object_name_normalize(word(layout_name,1,"@")))
    'Test if pointer is valid
    if is_object(tempP) then 
     'Test if pointer refers to a form or browse
     if tempP.class() = "form" .or. tempP.class() = "browse" then 
        dim flagIsBaseFilter as l 
      flagIsBaseQuery = .t.
      
      if flagIsBaseFilter then 
       'Apply the query to the form or browse as the Base query. (this means that 
       'the user cannot turn the query off, only add to the query)
       tempP.BaseQueryRun(query.filter,query.order)
      else
       tempP.QueryRun(query.filter,query.order)  
       
      end if 
      
      'then activate the already open window
      tempP.activate()
     else
      'Window is not already open, so open it
      varP_Rembrowse = :Browse.viewqueried(layout_name,query.filter, query.order )
     end if
    else 
     varP_Rembrowse = :Browse.viewqueried(layout_name,query.filter, query.order )
    end if

    A browse displays records from a table in a spreadsheet type view. If you want to display an "empty" browse you need an empty record.
    There can be only one.

      Mike, you should preserve the formatting in your scripts when posting things like this to the message board, please.

      Check this thread for the steps necessary to do this. Thanks.

        Hi,Tom, I did revise the first post. Hope that is what is needed.
        I did not know about the # formating. Sorry.

          Hope you will agree the formatting enhances legibility. Right?

          You may want to rethink your design.

          The easy solution to the immediate problem is simple, but leads to other issues. Here's what I mean.

          Your script could determine if there are any matching records before running the query. i.e. use the A5_GET_RECORDS_IN_QUERY() function first. If there are no matching record your script simply opens the browse and begins a new record. If there are some matching records your script does what it does now, and runs the query.

          The problem with this is that if you open the browse without a base level query or filter the user could enter records that don't have the necessary link field values in them.

            Re: how to open a browse with no records from a form

            So in other words I must create a blank record in the table of the browse, related to the main table, wether I need it or not?
            Or if I trap the error and send a code to create a blank record, right there. Could that be possible.
            See attached sample.
            In the form names if I click expand notes for susan I see that she has records.
            if I see peter, next record, I get the error.
            How can I bypass the error "no record in query" in case there are no records yet and proceed to enter a new one for peter?
            How could this be fixed, which is not a bug.

                  Mike,

                  I have attached your sample with revised code & field rule. I added the new form, Names_view. I hop it will help you.
                  I changed the 2nd Id field name and rule from "t_remarks" table.

                    Re: how to open a browse with no records from a form

                    Very slick, I will try to implement it.
                    I was working in something similar by using the browse in a form, instead of the browse by itself.
                    I was able to do it.
                    What I did was to open the form-browse twice and use the A5_GET_RECORDS_IN_QUERY(with matching idname inside criteria) to count and trap if there were records or not.
                    but in the case of a new record, it will show everyone else records; I got to not report any errors.
                    Thanks for the sample. very good.
                    What I will add to the form in case of the new record is a title like "Sorry no entry remarks yet, please enter the first remark". That will look good.

                      Re: how to open a browse with no records from a form

                      Another solution is to create a blank record without a note, just fill id_name every time a new name is created.
