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.

  • Display a photo from a file in a report

    I'm using Microsoft SQL Server so Image File Reference fields aren't an option to me. In my forms I've written an Xbasic routine that takes the unique property identifier from the current record and appends the directory path and uses the FileFind.Getfile command to locate all matching images for that property that are located in a separate subdirectory. The photos display perfectly on my form and I can even scroll through them. I placed a bitmap control on my report and copied the same code to my Details->OnRecord event limiting it to the first picture for the record (I only want one picture to display per record) but I can't reference the Bitmap Control from Xbasic to assign the new file name. When I run the debugger it shows that Parentform::Map_No.value (or any other control I attempt to reference on the report) is invalid. I've looked through the forums and I've not seen any solutions to using external .jpg files with desktop reports and SQL Server as the data source. Any assistance would be greatly appreciated!

    Here's the code from my Report->Sections->Detail->OnRecord event.

    ' Clear the file array before using it on each record
    filearray.clear()


    ' Get the map number from the Map_No textbox on the current record
    currentmap = parentform:Map_no.value


    'Set the file path
    path = "\\developer\c$\Inetpub\ftproot\bcpva\Photos"


    'Now look in the photos directory to see if any photos match the current Map_No
    files = filefind.get(path+chr(92)+alltrim(currentmap)+"*.jpg",4096,"PN")


    'Fill the filearray with a list of all matching photos
    filearray.initialize_properties("name",files)


    'Check to see if there are any matching photos and if so display the first one
    if filearray.first_empty()>1 then
    ' check for multiple photos and only show the first one for now
    parentform:Control_Bitmap1.Bitmap.Filename = filearray[1].name
    parentform:control_Bitmap1.object.visible = .t.
    else
    ' Don't display the bimap control if no photo is available
    parentform:control_Bitmap1.object.visible = .f.
    end if

    Thanks...

    Re: Display a photo from a file in a report

    I've fixed the issue. The problem was using the Parentform: modifier in front of my object references. Apparently on reports you don't need this to identify the top level as the Detail->OnRecord event is already pointing to the report top level. Anyway, the above code works flawlessly now once I removed all references to ParentForm.

    Thanks!

      Re: Display a photo from a file in a report

      Just in case some else needs to use code that displays a photo from a file on a report that is tied to a specific field value on the report, here's the working code using the Topparent qualifier to make it relative to the specific report:

      'Check to see if there are any matching photos and if so display the first one
      if filearray.first_empty()>1 then
      ' check for multiple photos and only show the first one for now
      topparent:Control_Bitmap1.Bitmap.Filename = filearray[1].name
      topparent:Control_Bitmap1.object.visible = .t.
      else
      ' Don't display the bimap control if no photo is available
      topparent:Control_Bitmap1.object.visible = .f.
      end if
