What does Heap Check mean ?

that means that you have a trunking system that has no sites assigned to it. If you do not have a 3rd party PC software, download PSREdit 500 from here ( 30 day free trial) Upload to the program then back to the radio and it will clear the heap error. http://www.psredit.com/psredit500/download.html

it must be saying heap memory, that is ram of your mobile, it only happens when you run a game or app using high heap memory, or try to clean phone memory!

Most digital cameras will work with only with specific memory cards. You can't just buy any old card and expect it will work in your camera. Approved cards for Nikon E5700 are listed on page 159 of the English version manual. (In the Technical notes.) Also, if you insert or remove the memory card with the power on it could render the card unusable and, of course, you must insert the card in the correct orientation.
I assume you have not taken a heap of images in high resolution and simply filled your new card.

Kab ye error msg display karta hai pura question saaf saaf likho
there are many types of java error which occurs in different conditions

Your post is confusing, are you saying that photos which were once properly exposed are now black, i.e. underexposed, or have they disappeared completely?? Neither is believable.It is to be the camera, unless the problem is that the camera can no longer read the card.I am afraid your information is not clear enough Take the card out and check what is on it in your computer or someone else's if you don't have one. Try a different card (preferrably a different make) in the camera, just take some random shots and see what happens. Please report back.

this mean that your cell phone has not that much ammount of memory to deal with that software

After doing further research online I found that all I had to do is remove the battery and put it back in. It works perfectly now.

Install a memory card and turn the camera on. Look in the Setup menu, and there should be a "Backup" or "Copy" entry which will let you copy pics to/from internal memory.

Move it a bit (some half circle)back and forth. The slot may be in wrong position related to the roll inside. It should click in when you get the slot in right angle.
