Free Screen Capture for Windows 7

After upgrading my laptop from Win XP to Win 7, I was unable to use ZAPGRAB as there is a compatibility issue with Win 7. For working in Win 7 you need to download the LICENSED version of ZAPGRAB. I have found many free screen captures programs on internet that can fulfill my requirements as ZAPGRAB do but didn’t find any good one.

After a lot of searching I have found “Greenshot” which is better than others & can also use in WIN 7. It’s an open source program.

Here is an download link of Greenshot official site

Where i am ??

Since long time i have written something in my Blog. I was too much busy with my new Job Profile.. exactly.. SAP. I am happy with it at least I am doing something different & giving my services to Global Clients. Presently Working as SAP Basis Consultant.

Since i have joined from the day 1 to till date.. every day is a new day & new learning for me. As i am not a good listener(comments from my some friends) but i will try to catch the things..

SAP is divided in 3 things.. Operating System, Database & Application. I am trying to learn one by one. Now a days my total focus on learning Java Technologies & Java integration in SAP. How ABAP+JAVA works together. It’s very difficult to understand as sometime, it’s give me confusion as in SAP you can do same things in several ways. But still my study about JAVA going on..& i hope i will complete it soon. I will try to keep update my blog.

Till then good bye..

My Working

Hi to All,

I am just busy up with my as usual work but in between i got some to enjoy with friends & also integrate some new things in software. From Last 2-3 days i was trying to implement linux firewall for my own company but unfortunately due to reasons, i was unable to accomplish my work. This is worth while saying that Engineer Can work for others but when they mend to their own they are “Good For Nothing”.

Well many pplz who are using Windows different version.. they always go through the Accessories feature of Windows & found MS-Paint over there.. But most of the pplz never use MS-Paint for any creation, editing.
