Re: How to insert a background image to a webbrowser control? King of Kingz23-Oct-07 19:06 King of Kingz 23-Oct-07 19:06  Thx 4 ur reply. i m building a html editor in vb.net. 2 do so i m using webbrowser control. all i want, when user uses this software, he can insert a background image to document. i have done this like Dim openDlg As New OpenFileDialog openDlg.Filter = "BMP Image|*.bmp|GIF Image|*.gif|JPG Image|*.jpg" If openDlg.ShowDialog() = DialogResult.OK Then Dim Tempstr = openDlg.FileName Dim fileName As String = "" For Each ch As Char In Tempstr If ch = "\" Then ch = "/" End If fileName += ch Next Tempstr = "<title>" + str + "" webbrowser1.DocumentText = webbrowser1.DocumentText.Replace("King compressed drive tnaveen22-Oct-07 1:27 tnaveen 22-Oct-07 1:27  how to find compressed drive or folder programitically naveen Re: compressed drive Guffa22-Oct-07 2:03 Guffa 22-Oct-07 2:03  Check if the Attributes flags of the DirectoryInfo class contains FileAttributes.Compressed to see if a directory is compressed. --- "Anything that is in the world when you're born is normal and ordinary and is just a natural part of the way the world works.

I want select one of them and edit. then I use panel.refresh() to update the lines. because all the lines are redrawn and there is strong flash, how to avoid this? thanks Re: How to update only selected lines Christian Graus22-Oct-07 1:32 Christian Graus 22-Oct-07 1:32  Your best bet is to turn on double buffering. http://www.codeproject.com/csharp/DoubleBuffering.asp[^] Christian Graus - Microsoft MVP - C++ "I am working on a project that will convert a FORTRAN code to corresponding C++ code.I am not aware of FORTRAN syntax" ( spotted in the C++/CLI forum ) 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 ?
