If you don’t need synchronization , you can bypass it by passing the HEAP_NO_SERIALIZE flags to HeapAlloc, or HeapCreate, or both. VirtualProtect and IVirtualProtect VirtualProtect is a simplified version of VirtualProtectEx that works with only the current process. The VirtualProtect code is just the validation layer, with the real code in IVirtualProtect. The only validation performed in VirtualProtect is to determine whether the pfdwOldProtect pointer is either a valid DWORD pointer or 0. The IVirtualProtect code is just a wrapper around a call to VirtualProtectEx.

Pro Audio 9.0 was launched with support for Windows NT 4.0 as well as 95, 98, and 98SE, but apparently also runs well under XP. Pro Audio 8.0 is also claimed to be compatible with Windows 2000 on ntcompatible.com, so it’s possible that it might run under XP as well. Sonar 1.0 was optimised to run under Windows 98SE, ME, and 2000, despite few soundcards supporting the last at the time, but it will also run under XP, along with all newer versions. This mode allows older applications to think that they were running on a previous Windows version, which can solve a lot of problems. And let’s not forget applications that were using unreal mode – those always required “restart to dos “option.

Upgrading from Windows 3.x (Windows 95 Version A)

The most effective way is to change your display orientation in settings. We can choose if we want to change the orientation of the screen to horizontal, vertical or inverted modes, depending on the orientation of our monitor. Although it is most normal to always use the screens horizontally, operating systems, such as Windows, have functions that allow us to rotate the screen to position it in various ways. For example, we can rotate it 90 or 270 degrees to place it vertically, download here or rotate the screen 180 degrees to flip it.

  • Message queues are how window messages move through the system; they are described in Chapter 4.
  • Microsoft replaced its classic screenshot grabber by merging its features with Snip & Sketch.

Apart from a beautiful layout, the more important thing in an excellent PPT presentation is a clear logic and complete information to support the argument. Remember seeing that Windows.old folder knocking around your hard drive? That is your old installation of Windows, most likely Windows 10 if you’re having issues.

Can a Dell laptop’s screen be rotated?

The memory for the structure pointed to by this field is allocated from the KERNEL32 heap, so it’s always visible in the contexts of all processes. In contrast, the primary IMAGE_NT_HEADERS that’s located near the module’s base address may be below 2GB, so it’s accessible only to processes that have loaded that module. By making a copy of the IMAGE_NT_HEADERS that’s accessible in all contexts, KERNEL32 can easily locate the information for any loaded module without calling up into ring 0 to switch memory contexts. 63 unlike the Winl6 TOOLHELP. DLL, which is separate from KRNL386, the TOOLHELP32 functions are implemented in KERNEL32.DLL, which is where they belong. One problem with implementing these system information functions in Windows 95 is that Windows 95’s pre-emptive multitasking will screw things up unless special care is taken. For example, in the middle of walking through the thread list, the enumerating thread might get switched away from.
