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.

  • Why is this occuring?

    In my script, one option is to edit a file before processing it in another option, the trouble is , it will only work if I include the "ShowVar" statement for the variable ..

    the code in my script:

    Code:
    if left(a_dlg_button,18) = "vLogFileNameEvent_" then
        showFilename = .f.
        if a_dlg_button = "vLogFileNameEvent_popupdone" then
            vLogFileText = get_from_file(vLogFileName)
            showvar(vLogFileText)
            select
                case Len(rtrim(vLogFileText)) = 0
                    ui_msg_box("Error:","File "+file.filename_parse(vLogFileName,"n")+" is Empty",UI_ATTENTION_SYMBOL)
                    ShowEdit = .f.
                    a_dlg_button = ""
                case left(vLogFiletext,1) <> "#"
                    ui_msg_box("Error: ","File "+file.filename_parse(vLogFileName,"n")+" has no Header",UI_ATTENTION_SYMBOL)
                    ShowEdit = .f.
                    a_dlg_button = ""
                case else
                    ShowEdit = if(vOpt="Edit Logging",.t.,.f.)
                    a_dlg_button = ""
            end select
            a_dlg_button = ""
        end if
        a_dlg_button = ""
    end if
    If the showvar statement is excluded the script shows a blank variable, but when it is included the variable shows correctly. I've been stuck on this for weeks now and it is driving me nuts!

    when I created a test version with just this element, it works with or without the showvar statement. "Input Logging" option, just loads the file and does error checking.

    Code:
    dlg_title = "testing"
    showedit = .f.
    showfilename = .f.
    dim vLogFileText as c
    ui_dlg_box(dlg_title,<<%dlg%
    {region}
    (vOpt:Input Logging)(vOpt:Edit Logging)
    {watch=vOpt!vOptEvent}
    {endregion};
    {region22}    
    {condition=(ShowFileName=.t.)}
    {text=16vOpt}: [%p=ui_get_file("Input Log Filename","Log(*.Log)|Text (*.txt)",Filename_Decode("[Logpath]")+"*.log","X");I=$a5_smart_file%.81vLogFilename!vLogFileNameEvent_*]
    {endregion22};
    {region23}
    {condition=ShowEdit=.t.}
    Log: [%mw%.40,18vLogFileText]{sp=2}
    {endregion23}
    %dlg%,<<%code%
    if a_dlg_button = "vOptEvent" then
        showfilename = .t.
        a_dlg_button = ""
    end if
    if left(a_dlg_button,18) = "vLogFileNameEvent_" then
        showFilename = .f.
        if a_dlg_button = "vLogFileNameEvent_popupdone" then
            vLogFileText = get_from_file(vLogFileName)
    '        showvar(vLogFileText)
            select
                case Len(rtrim(vLogFileText)) = 0
                    ui_msg_box("Error:","File "+file.filename_parse(vLogFileName,"n")+" is Empty",UI_ATTENTION_SYMBOL)
                    ShowEdit = .f.
                    a_dlg_button = ""
                case left(vLogFiletext,1) <> "#"
                    ui_msg_box("Error: ","File "+file.filename_parse(vLogFileName,"n")+" has no Header",UI_ATTENTION_SYMBOL)
                    ShowEdit = .f.
                case else
                    ShowEdit =  if(vOpt="Edit Logging",.t.,.f.)
            end select
        end if
        a_dlg_button = ""
    end if
    %code%)
    Any suggestions welcomed.

    Re: Why is this occuring?

    Hi Graham

    Code:
            vLogFileText = get_from_file(vLogFileName)
           ' showvar(vLogFileText)
           'Try - refresh the value
            vLogFileText = eval(" vLogFileText ")  'or   vLogFileText = replacement_parmeter( vLogFileText,local_variable() )
    and are you sure about this "popupdone" event name is a part of the function from A5?
    if a_dlg_button = "vLogFileNameEvent_popupdone" then

      Re: Why is this occuring?

      the crazy thing is that the same code works fine in a previous incarnation of my script! using popupdone (found this was only way of getting file. discovered it whilst using trace.writeln(a_dlg_button) to what was happening.
      I have since copied and pasted the code from the old script (where it worked) into the new, but still get the same result !!

        Re: Why is this occuring?

        I tried your script with a text file that I added the '#' to and it worked fine with the showvar() commented out. I selected the Edit Logging option. The Input Logging option however didn't do anything when I selected the same file...

          Re: Why is this occuring?

          Thanks Robin, "Input Logging" just loads the file and checks the header record, for processing later.

          Code:
          dim shared vEditLogFileText as c
          dim shared vLogFileName as c = "I:\my databases\aviation\logging\*.log"
          ui_dlg_box("test",<<%dlg%
           [%p=ui_get_file("Open Filename","Log(*.Log)",vLogFileName,"X");I=$a5_smart_file%.81vLogFilename!vLogFileNameEvent_*];
          Log: [%mw%.40,18vEditLogFileText]{sp=2}
          %dlg%,<<%code%
          if left(a_dlg_button,18) = "vLogFileNameEvent_" then
          	if a_dlg_button = "vLogFileNameEvent_popupdone" then
          		ShowFileName = .f.
          		vEditLogFileText = get_from_file(vLogFileName)
          		select
          			case len(rtrim(vEditLogFileText)) = 0
          				ui_msg_box("Error","File is Empty",UI_ATTENTION_SYMBOL)
          			case left(vEditLogFileText,1) <> "#"
          				ui_msg_box("Error","File has no Header",UI_ATTENTION_SYMBOL)
          		end select
          		showEdit = .t.
          		a_dlg_button = ""
          	end if
          	a_dlg_button = ""
          end if
          
          %code%)
          I changed the Variable name so that is only used in this section.
          I copied the relevant code from my main script as above, which as you found out works fine without the VarShow statement
          going to have a long lie-down in a dark room :)

            Re: Why is this occuring?

            This gets weirder and weirder!!

            I have split the "Edit Logging" and "Input Logging" into separate code. so you can forget "Input Logging", works just fine.

            Code:
            if left(a_dlg_button,19) = "vEditFileNameEvent_" then
            	showEditFileName = .f.
            	if a_dlg_button = "vEditFileNameEvent_popupdone" then
            		vEditFileText = get_from_file(vEditFileName)
            		trace.writeln(vEditFileText)
            		ShowEdit = .t.
            	end if
            	a_dlg_button = ""
            end if
            the file is still displayed as empty, BUT, the trace write displays correct data ????????????????

              Not to be a smart aleck - but did you check the .log file in explorer? Maybe you can add _log to the name and give it a .txt extension instead...

                yes, tried it with .txt and same result. The same file used in the "Input Filename" displays the correct data when processed !!

                  Re: Why is this occuring?

                  Do you want to see the file displayed when vOpt=Input Logging and the case else statement is triggered?

                  Because this statement won't do that since it will always be false:

                  ShowEdit = if(vOpt="Edit Logging",.t.,.f.)

                    Re: Why is this occuring?

                    I have rewritten this event removing any outside references. The "Input Filename" now has its own event which seems to work, so will leave that alone.

                    all I have left is this

                    in the dialog

                    Code:
                    Edit:  [%p=ui_get_file("Edit Filename","Log(*.Log)",vEditLogFileName,"X");I=$a5_smart_file%.81vEditLogFilename!vEditLogFileNameEvent_*];
                    
                    Log: [%mw%.40,18vEditLogFileText]
                    in the code

                    Code:
                    if left(a_dlg_button,22) = "vEditLogFileNameEvent_" then
                    	if a_dlg_button = "vEditLogFileNameEvent_popupdone" then
                    		vEditLogFileText = get_from_file(vEditLogFileName)
                    		a5_show_variable(vEditLogFileText,"vEditLogFileText")
                    	end if
                    	a_dlg_button = ""
                    end if
                    presumably, I have to leave the a5_show_variable in place, to allow the script to run, as I cannot see any other way around it, given my limited experience with xdialog.

                      it could of course be caused somewhere else in the script, but the only references to the edit file are as above !!
                      This is crazy, as it has taken me eleven months to get to a nearly finished script. I have learnt and used all sorts of methods and functions to make the thing work, but not something as simple as this .

                        even more confusing, below is code from an early version (that works using same test file).

                          Graham,

                          You have applied
                          Code:
                          [%p=ui_get_file("Input Log Filename","Log(*.Log)|Text (*.txt)",Filename_Decode("[Logpath]")+"*.log","X");I=$a5_smart_file%.81vLogFilename!vLogFileNameEvent_*]
                          and I am not sure you can apply it(Filename_Decode( ) with UI_get_file() or not.

                          See my code and is it what you want?

                          Code:

                            Thanks John,
                            will have a look.

                            Ive been using the "popupdone" event for months and it works every time!!!

                            "Get_From_file" is an A5 function

                            GET_FROM_FILE()

                            Syntax

                            Data_String as C = GET_FROM_FILE( Filename as C )

                            Argument
                            Description

                            Filename
                            The fully qualified name of a file.


                            Description

                            GET_FROM_FILE() opens a file specified by filename and reads the contents of the file. Returns a character string with the contents of the file. This high level command is easier than using the low level FILE.OPEN()and <FILE>.READ()methods.

                            Supported By

                            Alpha Five Version 5 and Above

                            Example

                            This script sets the value in a variable to the contents of a text file.

                            dim text1 as C
                            Filename = "f:\a5\test2.txt"
                            Text1 = get_from_file(filename)
                            dim text1 as C
                            Filename = "f:\a5\test2.txt"
                            Text1 = get_from_file(filename)
