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.

Strip path from file reference ?

    Re: Strip path from file reference ?

    Well I guess this made it, superb, I am really getting to like this software, thanks you all ;)

    'Prompt for a filename and store result in a variable called 'ImgName'.
    dim prmpt_title as c
    dim prmpt_filter as c
    dim prmpt_default as c
    dim prmpt_flag as c

    prmpt_title = "Select image file"
    prmpt_filter = "(*.jpg*)|(*.jpeg*)"
    prmpt_default = ""


    ImgName = ui_get_file( a5_eval_expression(prmpt_title,local_variables()),prmpt_filter,prmpt_default,"X")

    'Set 'Value' property of 'Customer_pict in Form 'Customers' .
    DIM window_name as C
    window_name = ":"+"Customers"
    DIM varP_Object as p
    'Get a pointer to the specified window
    varP_Object = obj(window_name)
    'Check if the specified window exists
    if .not. is_object(varP_Object) then
    ui_msg_box("Error","The window '"+window_name+"' does not exist.",ui_stop_symbol)
    ImgName = file.filename_parse(ImgName,"NE")
    varP_Object:Customer_pict.value = ImgName
    end if


      Re: Strip path from file reference ?


      Note that the script you have was probably written from an A5 genie and, as such, includes a lot of "just in case" stuff. For example, it appears to be checking to make sure the Customers form is open. However, if you start to code directly with xbasic and you are only running the script in the form, then all that other checking isn't important. As a result, it could be simplified to:

      ImgName = ui_get_file( "Select image file", "(*.jpg*)|(*.jpeg*)", "", "X")
      IF ImgName <> ""   'In case user cancels
          ImgName = file.filename_parse(ImgName,"NE")
          parentform:Customer_pict.value = ImgName
      END IF
      I point this out just in case you were getting "scared" by the complexity of the code. Much of the genie created code seems very complex and 'round-about'. Don't let that scare you - it doesn't have to be that way except that genies have to be designed to handle all kinds of unknown situations. The code can be much simpler once you know exactly how something will be used.

      Also note that my code even adds a "safety" in case the user cancels. The original code would only be three lines. Even most of the DIM commands become unnecessary. On the other hand, maybe you would want to leave out the IF and just save a blank value. However, as a matter of "good programming", I think I'd prefer to have a "delete the current image" button instead because (a) the user could then cancel the image selection without blanking out the value and (b) it would probably be much clearer to the user.

        Thank you for your input, I was not too scared ;) and I think the code is quite explicit, not to worry.

        And yes I too prefer the option of the 'delete image' this is what I normally do in my apps, much clearer as you point out.
