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.

    don't allow to edit the data in the past

    Hi all,

    Please recommend me what command is the best to protect the data from user to edit it?
    I have table and user will key in it everday. Usually user can press Page up and PageDown to view and edit the data from form.
    How and what command I have to use to protect user to edit the previous data they key in yesterday or the day before yesterday. I don't want them edit the data in the past. They can create and edit only with in current day

    I know the modal and modeless but I don't know how to force form to modal if it's not today. (if it's not today and form will be setup to modal)
    I don't know other command that meet this requirement.

    Thanks
    Peter

    In the OnActivate event:

    Code:
    [COLOR=Blue]t =table.current()
    [/COLOR]
    [COLOR=Blue]If t.date < date()
    [/COLOR]
    [COLOR=Blue]This.allow_change(.F.) 
    [/COLOR]
    [COLOR=Blue]else 
    [/COLOR]
    [COLOR=Blue]This.allow_change(.T.) [/COLOR]
    [COLOR=Blue]end if[/COLOR]
    You might also need it in the OnFetch event if you allow fetching.

            Any variable that references a table like

            t =table.current()

            is a pointer (dot) variable.

            Dim t as P

            is proper but not necessary. The assignment statement implicitly defines it.

            Using the pointer variable you can reference the fields in the table like

            t.fieldname using an actual fieldname
            There can be only one.

              Hi Stan,

              Thank you for your more details for the pointer variable.
              I have never used it before and I have to learn it more how to use it
              I think it's time to use it many places in my application

              Thank you for advise

                Hi Peter,

                Thank you for your sample I can do it now.
                Is it possible if I use more condition to allow user edit the data
                I use the save botton and add more command after save record to set the status of some field to t/f (to protect user change clock in PC)

                I have more a field for status in the table

                id date expense status
                001 3/3/2010 500 T
                002 4/3/2010 620 F

                when user key in the data within form and click Save botton then I have a command (next command to save record) to set the Status field to T

                so when user click save botton. He will cannot edit the data evenif he try to change clock of PC.

                The problem is I don't know what command I can use and add more in the Save botton to force the Status to T

                Thank you for your commandation.

                  Maybe in the CanSave event you put something like:

                  FieldObjectName.value = .T.

                  The CanSave fires before the Save event. It might work in the save event too, but I forget. Yow will need to put the field on your form, but you can hide it. Usually, Alpha automatically gives the field object the same name as the field itself.
