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.

Progressive Find

  • Progressive Find

    I am using the AlphaSport progressive find and I think it has a bug. When I enter a record into the Customer table with lastname as "ZZZZZZZ", the progressive find does not display
    the record in the listview. It looks like a record is not displayed if the last entry into the table will sort to the bottom. However if I sort the list in descending order the record appears.

    Is there a fix for this? Any Idea on how to fix it.
    I really would like to use this code as it does most
    functions I need very nicely.

    Re: Progressive Find

    I have found the customer form in the AlphaSport database to function poorly. The multistate button A-Z does not work well. If you press any letter except "L", and then press "L", There is only one listing... Litton. You can't get this customer into focus. And then more button presses do not work correctly. Also, the filtering for the table with the multistate button and the progressive lookup have a conflict, because if you use the multistate to filter the table, and then try to goto a customer with the progressive lookup, it won't. The progressive lookup button needs a "show all" command to brake the filter placed on the table by the multistate button. And the progressive find fails to be able to acquire the last record in the table.

    It's not really a goo demonstration of the complete programming needed.

      Re: Progressive Find

      Here is a progressive lookup UDF for the Customer table for the Alphasport sample database. It requires a new field be generated in the customer table named alphaname with a calculated field rule of: ALLTRIM(LASTNAME)+", "+ALLTRIM(FIRSTNAME) and then right click on table in control panel and select Utilities > Recalculate Calc Field (Field Rules)

      Code:
      FUNCTION customer_progressive AS C ( )
      
      ' this is a progressive search for a Customer 
      
      ' clear filters
      	dim t as P
      	t=table.current()
      	t.query_detach_all()
      
      
      'Create an XDialog dialog box to prompt for parameters.
      SEARCHAGAIN:
      	DIM SHARED vCustomer as C = ""
      	DIM SHARED vLLCustomer as C
      	DIM SHARED vresult as C
      	DIM vLLCustomer_rl_def_orig as C 
      	vLLCustomer_rl_def_orig = "kl=Customer,{keylist_build(\"H=.05,1:12[Customer_Id],2:25[Alphaname]\",''+recno(),left(''+Customer_Id,12),left(''+Alphaname,25))}{left(alphaname,len([varC->vCustomer])) = [varC->vCustomer]}"
      	DIM vLLCustomer_rl_def as C 
      	vLLCustomer_rl_def = replace_parameters(vLLCustomer_rl_def_orig,local_variables())
      	vresult = ui_dlg_box("Customer Search",<<%dlg%
      	{background=#185,175,135}
      	{region}
      	{lf};

      'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

      'Go to a specified record number in Form 'Fs_visit' at parent level.
      	DIM var_recno_target as N
      	var_recno_target = val(vLLCustomer)
      	DIM object_name as C
      	object_name = ":"+"Customer_Information"
      	DIM varP_Object as p
      	'Get a pointer to the specified object
      	varP_Object = obj(object_name)
      	'Check if the specified object exists
      	if .not. is_object(varP_Object) then 
      		ui_msg_box("Error","The object '"+object_name+"' does not exist.",ui_stop_symbol)
      	else
      		varP_Object.recno_goto(var_recno_target) 
      		end
      	end if

      	display_error:
      	msg = "An error occured in the choice of Customer "
      	ui_msg_box("Error", msg,48)
      	GOTO SEARCHAGAIN
      
      END FUNCTION
