i am trying to get the text but only i am getting this [ ], y dont know why dont exist a comunication between the read from and the block got text, its like dont comunicate correctly and i cant get the csv text. someone help?
when i put the call read from inside a button and use the select list item list with a number index works but i need to use the listview1.selection index
read a file inside the gottext event? infinite loop?
i am trying to get the text after picking the listview but i cant get the text. someone helpme
i am not getting infinite loop.i am getting no comunication between the read from file and got text from csv to text in the list.
the system that i am trying is to access to the csv files using listview after picking the correct listview selection index but dont work. and i dont know why. maybe because the comunication between the block read from file and got text file are broken
then you need to read the file in listview. afterpicking, not in file.gettext .
and show indexselection on a label to see if it's the correct file name/path.
i make that but the indexselection show me that the label is empty. but if i make the read from in the button. when i make that works but i need to use in the block select item list, the index use a number, not the block index selection that i need to use this block. so i am confuse why dont work the read from filename inside block after picking. i am thinking that to work the read from filename not working inside after picking because the comunication between got text block to get the text from csv dont store the information in my list csv and inside the block after picking dont call the text inside my list csv because i am trying many forms and always are empty [ ].
someone can help me why are not communication between my listview and the mfile extension trying to get text using index selection?. someone can help me?.
Are your blocks now any different to the one's you showed in your first post? If so, show your latest blocks.
this is my blocks and my aia
but using the read from block in this form inside button and replace index selection for a block number. i can access to the csv content .
so i think that the read from block cant get correct comunnication between got text csv and after picking list view block in the first aia and first image
i am showing my blocks and my aia and no body can guide me why arent a comunication between mfile read and got text file with after picking block from listview?
What about posting only the relevant blocks to make is as easy for others to help?
Your post is confusing...
