Jairo A. Murillo I #1 / 8	unload forms or frames Hi everybody I did a develop in my PDA under embedded VB, I have a problem with my forms and frames. During the program execution this open several forms, when I have 4 or 5 forms opened the system close due "memoy is not enough" any idea abou it?, do you know how can I close each form or frame once I go to another one in the program ? Thanks in advance. -- Jairo Alonso Murillo I.

Will Olso #4 / 8	unload forms or frames Hello Jairo, I have developed several applications with EvB and I suggest that you only use one form per application and use Frames to "simulate" form actions such as hide or unload. By using Frames you economize on memory because forms are so memory intensive and you load all the frames up at the app.start so... take the performance hit at first and simply make the frame.visible = true or false depending on your app and its flow. Just some ideas ! Will With Quote: >-----Original Message----- >Hi everybody >I did a develop in my PDA under embedded VB, >I have a problem with my forms and frames.

Christoph Eisenman #6 / 8	unload forms or frames Hello, I tried this, but it did not work in my case. No memory got freed , no load event fired the next time I tried to load the form, so I guess that the evb WinProc is just hiding the form in case it receives WM_CLOSE. Or, I am doing something wrong?! Please could somebody from Microsoft comment on this thing!!!

Anthony Marchin #8 / 8	unload forms or frames Dhandapani, I had asked this a while back, and decided to test if for myself. On my platform, the close command you send to the form acts no differently than hide. The formload event never fires again. I have also used the GlobalMemoryStatus API call to check memory usage. At least on my setup, memory goes up but it does not go back. Your method would recover no memory. The fact that it doesn't work for me at the very least shows that your solution is not universal.
