Fastest bitmap display MCING19-Aug-03 23:25 MCING 19-Aug-03 23:25  I'm currently working on a videosurveillance software. I have to display, as fast as possible, sequences of bitmaps, with streching possibility. I'm using VisualC++ 6.0, and I'm looking for someone who tried different ways to display such images : - drawdibdraw family functions - strechdibits functions - opengl texture mapping - directx - ... others ? My goal is to find the FASTEST way to do it, whatever method. Thanks Mickey MMX optimization sharlila19-Aug-03 23:14 sharlila 19-Aug-03 23:14  Anyone knows how to work with 24bit pictures? For negative it's not a problem, I just subtract every RGB value from 0xFF and it will be fine. But let's say we want to do a gray calculation like so: (3*red + 4*green + 2*blue)/9 for each RGB pixel. Since I have to use 8bytes in calculations, I get in 2pixels and 2 extra bytes which will just be there. mm0: RR GG BB RR GG BB RR GG and the next sequance will be: mm0: BB RR GG BB RR GG BB RR You see my problem? How can I still use MMX to do this in 24bit pics? thanks Saving a dropped file into a specified folder YolandaSteyn19-Aug-03 22:53 YolandaSteyn 19-Aug-03 22:53  Hi I am using a drag and drop to install a license file. How can I take the dropped file and save it to the install directory of the software? I used an environmental variable to get the directory path where the file needs to be saved eg: char *ptr; ptr = getenv("LM_LICENSE_FILE"); I can do it using dialogs, but I need an alternative way, please help urgently!!! How to convert TCHAR[] to CString? Exceter19-Aug-03 22:30 Exceter 19-Aug-03 22:30  Hi, how to do it properly? I tried following: TCHAR tch[20]; CString str; ..... str = tch; but Have an error, do not what kind of, know that because of the assignment. Thanx. Re: How to convert TCHAR[] to CString?

I've found the following ways: 1) In System.ini, the [mci] key 2) In registry the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\MediaResources\mci key 3) I'm not sure, but can one use the wDeviceID like an index? Which is the correct way? Or even another way to do it?

I have two ATL objects, A and B. object A can be create from a method of object B. the user of this COM, should not directly create A in its code, but get one from object B. I don't know how to stop the user from creating A directly. Any idea? Re: problem of ATL Steve S19-Aug-03 22:05 Steve S 19-Aug-03 22:05  1. Don't supply a coclass for A in the IDL 2. Remove A from your object map in the main CPP file for the project However, you will need to make sure that the interfaces that object A provides are declared in the library block of your IDL file, or it won't 'publish' the interfaces in the TLB/DLL.

Thanks Neil Re: How do I hide an application from taskbar Brian Delahunty20-Aug-03 1:52 Brian Delahunty 20-Aug-03 1:52  When the window is being created (probably be calling Create) include the WS_EX_TOOLWINDOW style and it will always hide the taskbar 'bar'.

Neil Re: How do I hide an application from taskbar Ryan Binns20-Aug-03 5:29 Ryan Binns 20-Aug-03 5:29  WS_EX_TOOLWINDOW is an extended window style. You need to include it in the dwExStyle field, not the style field.
