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.

  • Xdialog Imageviewer won't display on open

    I have an xdialog with an {Imageviewer} control. Once the xdialog is open, clicking on a file name in the image list shows the image. I've tried various ways to get the first file in the list to show on startup, but without success. The first file in the text file list opens just fine on startup.

    Here's the code
    dim lv as p = local_variables()
    dim imgpath as c = A5.Get_Exe_Path() + chr(92)
    dim computer_name as c = api_getmachinename()
    Dim format as p 
    Format.odd_selected_color="Dark Blue"
    Format.even_selected_color="Dark Blue"
    dim imgs as C
    dim txtfiles as C
    dim varC_result as C
    dim dlg_title as c = "MANUAL DL INFORMATION ACQUISITION"
    dim iv as p
    iv.width = 0
    iv.height = 0
    iv.loadEvent = "Load"
    dim mode as c
    ImgList = filefind.get(imgpath + "*.jpg",file_find_normal+file_find_not_directory,"N")
    auto_list_imgs = ImgList
    'Apply 'owner draw' formatting information to the list
    auto_list_imgs = a5_owner_draw_list_fmt(auto_list_imgs,Format)
    temp_count = w_count(auto_list_imgs,crlf())
    DELETE a_imgs
    DIM a_imgs[temp_count] as c
    dim image_name as c = ""
    'if imglist <> "" then
    '	image_name = imgpath + word(imglist,1,crlf())
    'end if
    TxtList = filefind.get(imgpath + "*.txt",file_find_normal+file_find_not_directory,"N")
    auto_list_txtfiles = txtlist
    auto_list_txtfiles = a5_owner_draw_list_fmt(auto_list_txtfiles,Format)
    temp_count = w_count(auto_list_txtfiles,crlf())
    DELETE a_txtfiles
    DIM a_txtfiles[temp_count] as c
    if alltrim(txtlist) <> "" then
    	dim file_name as c = word(txtlist,1,crlf())
    	file_name = imgpath + file_name
    	dim fileinfo as c = file.to_string(file_name)
    end if
    dim explaintext as c = GetExplainText()
    heading_string = "The image file name prefix (under \"Available Images\") must match the driver's license number EXACTLY for the \"Auto Acquire\" to work properly. The text file prefix (see below) must also match exactly.\

    End Function
    Any suggestions?

    Re: Xdialog Imageviewer won't display on open

    Problem solved. These old eyes of mine aren't getting any better. I had inadvertently removed the {startup=init} directive from the dlg_code section so that any code I was sticking in the init event wasn't working. Duh!

      Well at least you showed us your code - that is always good to see!
