Similar posting a week or so ago regarding charting: Graph Controls[^] Also have a search through the articles on this site... there's lots and i am sure one or two should be suitable to your needs. Hope this helps Tom

Any suggestions Leave your mark wherever you go

The usual way to resolve this is to store the correct index / or a pointer to the data using SetItemData and GetItemData methods of CListCtrl. Have a look on MSDN for those two functions. There should be a good example. Michael CP Blog [^]

I hope there is nothing attched before you make those calls to Detach() or your program will have resource leaks. After drawing to the bitmap via Rectangle, select pOldBitmap into MemDC. If either function SetBitmap() or Save() needs to select it into a DC, then neither one can do it until MemDC releases ownership. A bitmap can only be selected into one DC at a time. INTP

What about the function BitBlt, with the SRCCOPY flag. That copys from one DC to another?

Thanks i will check it and will come up back Leave your mark wherever you go

You having a 1 X 1 pixel bitmap in your memdc tells me that the bitmap selected into it is the original default bitmap that all memdcs have. You have at some point selected your bitmap out of the memdc. If I were you, I would make the bitmap (CBitmap or HBITMAP) a member of your class. That way you only have to create it once. Select it into a memdc to draw on it, and select it out again when done. You can then pass that bitmap to your save function. Remember, it is the bitmap that stores your image, not the DC. The DC is just the means that you use to draw onto a bitmap.

Please follow the following link for better idea http://www.codeguru.com/forum/showthread.php?s=d09323bd39f2dd0a942e34fe1155af42&threadid=296795 My main aim is to draw the content to view such that when user wants he can save the same to image file. Thats it? What i tried that i drawn completely into the ClientDc and at the end (see first post) i am making the memory device context and then storing teh content to the image file. Well but it seems that MemDC is taking the complete Mainwindow instead of the required clientdc. Help me in this regard Thanks in advance sandeep Leave your mark wherever you go

Help topics are usually linked to different elements (dialogs, views) of your app. Here's what I do (which is slightly different from MS' process):* For every dialog (eg: CMyDialog), define a unique constant (eg: Help_MyDialog). Keep these constants in the file MyAppHelp.h. Include this file as a map in your HtmlHelp project. Ids in the file will map to your .chm's topic ids. Add a "Help" button to your dialog. It's handler should execute this: HWND hWndHelp = HtmlHelp (NULL, strHelpFile, HH_HELP_CONTEXT, Help_MyDialog); where strHelpFile is the full path to your app's .chm file. Add a handler for the WM_HELPINFO message. This message is sent whent the user clicks the F1 key. In its handler, just call your Help button handler. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com

BitBlt copies data from one device context's drawing surface to another device context's drawing surface. CClientDC's drawing surface is the portion of the screen contained in your window, and your MemDC's drawing surface is the bitmap you select into it. A drawing surface can be anything: a memory bitmap, the monitor, a printer, a plotter, etc. [ ](http://www.canucks.com)Sonork 100.11743 Chicken Little "You're obviously a superstar." - Christian Graus about me - 12 Feb '03 Within you lies the power for good - Use it!

Hello in short and sweet I am having a case like this: Design is having Number of rows and Points per row (This are editable) Well user set the values for Number of rows say 4 and points per row 10 then system will make 40 objects and will store them the CObArray mentioned above. Assigned with each object is an ObjectID say 0,1,2,....,39. So above is the case when user mention all of the data provided and system stores them to CObArray NOW if user changes the NUMBER OF ROWS or POINTS PER ROW or both. say 3 and 12 ,then system has to take it into consideration and has to restore the previous rowwise data back to the new one. That is main theme and based on this only is my above query. Sandeep Leave your mark wherever you go

1.0 Yes! Because MemDC contains your bitmap and therefore is draw on your bitmap. Before calling CreateCompatibleBitmap() make sure that the bitmap does not already exist or you will have problems. DO NOT for get to restore the origanal bitmap to the MemDC after drawing to it. 2.0 & 3.0 The only reason for making MemDC global is so you will not have to call CreateCompatibleDC() more than once. You will still need to clean it up after evey usage though. That is call SelectObject(pOldBitmap) after drawing to bitmap or using MemDC to blit the image to the client area. Lookup CDC::CreateCompatibleDC() in the MSDN library (there is sample code there) INTP
