Many events in the structure of the event
Hello
My GUI application have increased over time and the structure of the main event now contains upward 150 events triggered GUI, mainly buttons both autonomous and in custom controls.
The performance of the application are no problem but I experience occasional freezes the application that freezes everything just the GUI and what I suspect most code running in the background. It is cleared by clicking anywhere on the front panel of the application and the same problem occurs in the development environment and in a bed .exe. To clarify, the application not falling down or stop, it all simply pauses or freezes and then resumes execution when the mouse click occurs. This happens randomly and at least a few minutes between.
I'm currently trying to track down the problem but thought id ask here if someone has experience of first of all structures of the event which handles a large number of events, or perhaps seen the same freeze happen in their application?

There is no watchdog, which could keep the change control, it is all managed by WinAPI, the application is just get it registered to receive messages.
The mouse click event or change of key value chain from interruption managed by the driver running at the kernell windows level.
Basically, the computer, if there is no user activity, consumes much resources from the PC to the active window with no event regarding the active window with many events.

Is it possible to prevent or remedy to have too many files in the DCIM folder?
Is it possible to prevent or remedy to have too many files in the DCIM folder? In a group of friends, when you view folders DCIM iPhone in Windows 8, three of us have many, many files (such as 101APPLE, 327APPLE, 328APPLE). Phones concerned: 5 c, 6: 6. Some have only one photo per file, some files have just a few pictures. In addition, two friends have files dated 1969. I think everyone has the most current ioS. What is the cause and is at - it a way to overcome it?
No, it isn't. The DCIM and its content was never for public use to shoot photos and videos.
Here's the right way to go about it.

I have a complaint on my Mac Book Pro. I bought my computer in January 2016 and it has two problems: the first is the display of the retina that has many traces of the keyboard and as many times it freezes. I have looked for help on the local Apple Store and support too, but it did not help. I would like you help me solve this problem.
Thank you.
Kelly
Your machine is still under warranty, so you should take it to your local Apple store for repairs. Function late in January, you bought it, you still have phone without support. If you can't find any help on the Apple Store, then I don't know what you expect to find here. We have no way to check for problems you have described or any additional hardware, etc.

How many pictures of the computer chip camera
How many pictures of the computer chip camera
So I can insert chip camera in my electronic photo frame.
If you read the manual of the device, it should give you more options, like "thumb drives". Also, the manual should specify the size in pixels, or MB size and explain how to transfer the photos.
In a generic sense, simply file copy photos to the card. Here is a guide.

Hello
I tried many combinations of the different pc in order to transfer files from one pc to the other and only max speed I have is from 4 to 10 Mbps.
I use the switch/cat6 cables only the router is capable of 100 Mbps.
Also, I connect the pc directly with cable and still the same speed.
Win7 will get more than that and how?
I read the other posts on this topic, but all patches are not applicable to me.
I used various cables and switches and PCs in order to eliminate the possibility of a defective unit.
Can you please help?
Thank you
Andreas
