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.

    Re: Display an image based on the on the contents of a database field.

    Not sure why you're typing that when you can copy and paste and edit or drag-drop from the xbasic explorer.

    parentform:bitmapobjectname.bitmap.filename = alltrim(parentform:Tables:tablename.fieldname)

    becomes

    parentform:MFGLOGO.bitmap.filename = alltrim(parentform:Tables:hallwebpagemfg.IMAGEPATH)


    I'll put together a sample and attach it.

    Re: Display an image based on the on the contents of a database field.

    Stan, thank you for trying to help me .. this is what I have found .. remember V11 ...

    I am in the Code Editor on the form called TestForm and doing this in Xbasic.

    When I start I type in "Te" and get the drop down options and see "Testform." which I select however it is "." not ":".

    I change it to a ":" and now get the bitmapobjectname "mfglogo".

    The string now shows .. "TestForm:mfglogo." and there is a drop down .. but there is not option "bitmap"

    If I can give you some details, perhaps that can help ...

    Form Name is "TestForm"
    Bit Map Object Name is "MFGLOGO"
    Field name is "hallwebpagemfg->MFGLOGO"
    the field object name that contains the full path to the bitmap file is called "IMAGEPATH"
    The Field name is "hallwebpagemfg->IMAGEPATH"

    When I try to entry your suggestion it is not accepted

    We use a bitmap field on the form and in the on_fetch event, we point the bitmap field to the image file name from the table.
    As Tom indicated, you use the onfetch event of the form. As the user moves through the records, the code processes the image name in the new record and changes the bitmap on the form to match.

    Tom, I just did more investigation as to your solution .. and we are running A5V11 .. and there is no such property (on_fetch) available.

    Re: Display an image based on the on the contents of a database field.

    parentform:bitmapobjectname.bitmap.filename = alltrim(parentform:Tables:tablename.fieldname)

    bitmapobjectname is the name of the bitmap object on the form
    tablename is the name of the table containing the field that holds the path and filename of the bitmap to be dsiplayed
    fieldname is that field

    We use a bitmap field on the form and in the on_fetch event, we point the bitmap field to the image file name from the table. the field is defaulted to a "no Image available" jpg when the form is developed.

    The solution depends on what you mean by

    to display on a form

    Do you want to be viewing a form and open the desired image in the native application for displaying that image type? - Use a button with the code sys_open(alltrim(yourfieldname.value))

    Do you want the image to be "embedded" in the form? - Add an image file reference field to the database.

    started a topic Display an image based on the on the contents of a database field.

    Display an image based on the on the contents of a database field.

    I need to display on a form, an image based on what is in a field within the A5 database ..

    example .. if the field "A" has c:\image.jpg" in it .. then on this form for this record, I need to display the image "image.jpg" . I can see how you can display the image if it is already store as a bitimage withing the A5 record ..

    Can anyone help .. A5 indicates that it can be done .. now I need to know how to do it ...

    tanx.. for your help
