Using DoPrompt in a button function

How about creating a separate function that is called by the DoPrompt button? This function collects the time values and either saves them to global variables or hands them off to another function.

I decided to write a separate function which deals with this non-ideal situation. Most of the time I'll just work out the entire dataset. I included the Prompt/DoPrompt to the button function so if the user just refuses to give anything it will go one way and if they enter something it will be read and handled to a separate function which works out the extracted data. Seems confusing but really simple for you programmers. :)

P.S. If someone is interested in what I did. Here is the function I use now.

 Function ButtonProc_21(ctrlName) : ButtonControl

    String ctrlName

    String format

    String left, right 

    Variable leftDP, rightDP // after reading input from user, left and right edge of the wave are saved in these variables

                             // these variables are later used to extract a part of the data (the interval we want to analyse)

    SetDataFolder root:

    KillDataFolder/Z root:SizeResolved

    SetDataFolder root:INCD

    Prompt left, "Enter left component" //Please enter a valid start point for the analysis, example: 01.01.2015 00:00:00 (dd.mm.yyyy hh:mm:ss)

    Prompt right, "Enter right component"  //Please enter a valid start point for the analysis, example: 01.01.2015 00:00:00 (dd.mm.yyyy hh:mm:ss)

    DoPrompt "Enter start and end times", left, right

    if (V_Flag)

        return -1

    endif

    Variable day, month, year, hour, minute, second

    format = "%d.%d.%d %d:%d:%d"

    sscanf left, format, day, month, year, hour, minute, second // read first entry (start time of the analysis)

    if(day<=0 || day>31 || month<=0 || month>12 || year<1999 || year>2100) // is the entry correct? test

        Print "Error in Date format. Please enter a valid date"

        return -1

    else

        leftDP = Date2Secs(year,month,day)

        leftDP += second + 60*minute + 60*60*hour

    endif

    sscanf right, format, day, month, year, hour, minute, second // read second entry (end time of the analysis)

    if(day<=0 || day>31 || month<=0 || month>12 || year<1999 || year>2100) // same for the second entry

        Print "Error in Date format. Please enter a valid date"

        return -1

    else

        rightDP = Date2Secs(year,month,day)

        rightDP += second + 60*minute + 60*60*hour

    endif

    if(leftDP >= rightDP) // this checks if you entered correct time interval. otherwise cancels the procedure.

        print "error - check your data"

        return -1

    endif

    if(!leftDP && !rightDP)

        buildSizeResolvedRatio()

        plotRatioData()

    else

        buildSelectedSizeResolvedRatio(leftDP,rightDP)

        plotRatioData()

    endif

End
