• How to Detect an Event Coming from the Firefox History Dropdown Box

  - by banterCZ

  How to detect an event coming from the Firefox history dropdown box? I need to distinguish between the enter key simply pressed on input field or on item from his native history dropdown box. The reason is that I would like to call custom submit button (not first one, which is default) on the enter key pressed on any input field.

• Problem with running a flash Program from pendrive

  - by rajivpradeep

  Hi, I have a USB drive with two partitions in it. one hidden and the other normal. i have an application which swaps the memory and runs the flash application in hidden zone. The problem is that the application works fine on windows7 and when run on WINXp, it swaps the partitions but doesn't run the flash applications but just keeps running in the background. I can see it in task manager. But, when i copy the application to desktop and run , it runs with no glitch I was facing the same problem on WIN7 too , but it was running as required when i ran it using "Run in Xp mode" and then i applied a SHIM and is running since then as required. the application is built using VC++ 2008 , What might be the problem.

• Better alternative to autonumber primary keys

  - by Comrad_Durandal

  I am looking for a better primary key than the autonumber data type, namely for the reason that it's limited to a long integer, when I really just need the field to reflect a number or text string that will never ever repeat, no matter HOW many records are added or deleted from the table. The problem is I am not sure how to implement something like turning the current date and time into a hexadecimal string and using that as a unique field I can use as a primary key. Am I just being too paranoid about running out of space?

• How is animation accomplished in these apps?

  Most of the Android users use the GO SMS app, and the iPhone users use their normal messaging app (Android rocks). Now, whenever a user types a message and presses the send button, the message's edit text field sets a glossy green background, also the green colored background comes floating at the back of the edit text field.

• VPS showing low disk space despite there is nothing major on it

  - by SheoNarayyan

  Hello experts, On my VPS server I was trying to see the used disk space and when I open My Computer it shows 17.9 GB free out of 39.8 GB it means that 21.9 GB space is used. However, when I select all files and folders from C: and try to see the total size, it just count approximately 11 GB. The difference is around 10 GB. Where is this 10 GB going if I have not stored anything else here? I asked above question from my VPS provider and he responded below Check hidden files/system files/etc. This is default windows OS and its utilization and not specific to setup. If you want specifics of usage, you can go ahead and get in touch with Microsoft support team and they'll provide you with exact specification of the same. I am sure that Windows OS must not be taking up 10 GB space for hidden files and folders. My VPS has Windows Server 2008 R2 installed. Can anyone help me in this on who is right?
