Re: How to update only selected lines Seraph_summer22-Oct-07 2:09 Seraph_summer 22-Oct-07 2:09  Hi, Christian, thanks a lot. I am not sure my problem can be solved by double buffering technique. I found that my problem is from the refresh itself. I mean: when I edit one line, for example, I try to drag this line by mouse moving, during mouse moving, the panel is refreshed again and again, and therefore all the lines are redrawn again and again. then all the lines show flash effects. even I use double buffering, after these lines are drawn in the memory, they are loaded on the screen, anyway, they should be refreshed again again. therefore, i think double buffereing can not solve my problem. maybe I should use different method to draw my lines. I would like to know your opinion. thanks again. Re: How to update only selected lines Seraph_summer22-Oct-07 2:06 Seraph_summer 22-Oct-07 2:06  Hi, Christian, thanks a lot.

I feel that its costly operation and it will kill my application. Would like to apply Lazy Loading approach to read data and place it over. Can you some one provide me an example that shows how it is being achived here C#? Re: Lazy Loading Christian Graus22-Oct-07 0:57 Christian Graus 22-Oct-07 0:57  Lazy initialisation is not going to help, you need to write code that maps your 2 gig file and searchs it without loading it at *all*, unless you're sure you're going to have the memory free to hold it.

If i do like this 1. Read chunk of data like 10 Meg per chunk 2. Place only on chunk on GUI and memory map 3. When ever we goes back and forth we can bring it from physical memory ? Will this alogirithm work out ? Any example like this? Re: Lazy Loading Christian Graus22-Oct-07 1:13 Christian Graus 22-Oct-07 1:13  You can't show 2 gig of data in your UI, no matter how you look at it. Yes, if you read it a bit at a time, that's probably a viable approach. My point is that lazy loading means to load an object as you need it. I suspect you meant more what I was suggesting, that you load it a bit at a time, right ?

Idea behid is reading bit of data and kept it as object and load into GUI. When we scrolls back and forth data model need to be get updataed. Or By using any Caching approach (Microsoft Patternts Library for Caching) can i have whole 2 gig of data into memory and load from it with out reading from physical file? Im working under 32-bit memory env hence it may support max. 2Gig size of data. Any hopes ?

List<myClass> Otherwise, you would do myClass[] coll = new myClass[10] ( for example, to create an array of 10 items ).
