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 do I subtract one property array from another to find the missing entries

    I have two property Arrays LogdataReg and DisplayReg.

    DisplayReg may or may not have the same records as LogDataReg.

    How do I subtract DisplayReg from LogDataReg to get the Missing Entries that are in LogDataReg but not in DisplayReg?

    I am only interested in the first field "REG" of each record for use in the comparison. In the sample setup the Missing Entries are "MISSING1" and "MISSING2".

    I have been trawling through Table of Contents in the Alpha Five Documentation, but cannot find anything that might do it.

    Re: How do I subtract one property array from another to find the missing entries

    Hi Graham,

    Here is one solution.
    I hope you don't mind but I did make a few changes for my sanity.
    This code will put the missing regs into the missingList.
    I changed missing1 and missing2 just to make things easier on my over-worked brain.

    Gregg
    Code:
    'setup test data
    
    dim shared DisplayReg[0] as p
    dim shared LogdataReg[0] as p
    dim shared LogData as c
    dim shared DisplayData as c 
    dim missingList as c
    dim checkList as c
    DisplayData = <<%a%

      Re: How do I subtract one property array from another to find the missing entries

      Thanks Gregg,

      nearly there.

      My Fault, I should have said that although I am only interested in the first field "REG" of each record for use in the comparison, I require the whole record to be in the Missing Entries array, not just the REG field.

        Re: How do I subtract one property array from another to find the missing entries

        Stumbled upon my own solution:

        Code:
        dim shared MyDisplayReg as U
        dim shared MyLogdataReg as U
        dim shared MissingReg[0] as c
        MyDisplayReg.initialize("1|2|3|4|5|6","1","1|2|3|4|5|6",DisplayData)
        MyLogDataReg.initialize("1|2|3|4|5|6","1","1|2|3|4|5|6",LogData)
        	KeyVal = myLogDataReg.first()
        	for n = 1 to MyLogdataReg.size()
        			Data = MyLogdataReg.get(KeyVal)
        			if .not. MyDisplayReg.exist(word(data,1,"|")) then
        				MissingReg[] = Data
        			end if	
        			KeyVal = MyLogdataReg.next(KeyVal)
        	next
        showvar(MissingReg.dump())

          Re: How do I subtract one property array from another to find the missing entries

          ok...just a minor change.
          Try this code.
          [code]
          DisplayReg.initialize_properties("reg|as|code|Country|H|When|where",DisplayData)
          LogDataReg.initialize_properties("reg|as|code|Country|H|When|where",LogData)
          '''LogdataReg.sort("A","reg")
          '''DisplayReg.sort("A","reg")
          '''for n = 1 to LogdataReg.size()
          ''' checkList = checkList+ LogdataReg[n].reg+"|"+convert_type(n,"C")+crlf()
          '''next n

          for each logreg in LogData
          ''' if DisplayReg.findI(logreg.value,"reg")=0 then
          if DisplayReg.findI(left(logreg.value,at("|",logreg.value)-1),"reg")=0 then
          missingList = missingList+logreg.value+crlf()
          end if
          next
          debug(1)
          ' The code below will add the missing items to the DisplayReg array.
          '''DisplayReg.initialize_properties("reg|as|code|Country|H|When|where",missingList,.t.)

          ' Uncomment the code below here to verify the missing data as been added to DisplayReg array.
          '''missingList = ""
          '''for each logreg in LogData
          ''' if DisplayReg.findI(left(logreg.value,at("|",logreg.value)-1),"reg")=0 then
          ''' missingList = missingList+logreg.value+crlf()
          ''' end if
          '''next
          end

            Re: How do I subtract one property array from another to find the missing entries

            Graham,

            Sometimes my best efforts are afterthoughts.
            This (in my opinion) is cleaner and easier to follow.
            I presumed you were going to add the missing logdataregs to the displayRegs, so I included the code to do that.

            Code:
            'setup test data
            
            dim shared DisplayReg[0] as p
            dim shared LogdataReg[0] as p
            dim shared LogData as c
            dim shared DisplayData as c 
            dim missingList as c
            dim checkList as c
            dim testList as c
            DisplayData = <<%a%
