I posted about this in the Newsgroup several months ago, but have not come across a solution yet so thought I should re-post somewhere else...
For a few of my analysis programmes I prompt the user for a name to save their results to a .xls/.csv file using uiputfile. Quite frequently the uiputfile dialogue fails to display and instantly returns 0. If I don't handle this it means the programme exits and the data is lost.
I did a test where I put the uiputfile command in a while loop (while fileName == 0) with a counter being displayed. I found that sometimes it loops around up to 5 times before the dialogue appears.
Can anyone help with this?? The two options of keeping the while loop (user can never cancel the save) or dumping the data to a fall-back file somewhere, are not that attractive.
I am using Matlab 2012b on Windows7. My original Newsgroup post (with at least one other victim of this) is http://www.mathworks.co.uk/matlabcentral/newsreader/view_thread/329926#908130
Thanks!
