So does HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations exist in the registry after the function returns, and is it gone when Windows is restarted?

one more thing is that when I use
bMove = MoveFileEx(_T("C:\\PAGEFILE.SYS"), _T("C:\\MovedPAGEFILE.SYS"), MOVEFILE_DELAY_UNTIL_REBOOT);
int aaa = GetLastError();
then bMeove = 0
and aaa = 5.
Please solve my problem.
Thanks

Which indicates access is denied. Do you have administrator privileges?
Why don't you just configure Wndows to do clear the page file automatically at shutdown:
Click Start
Click Control Panel
Click Administrative Tools
Click Local Security Policy
Click the "+" next to Local Policies
Click Security Options
Doubleclick "Shutdown: Clear Virtual Memory Pagefile"
Select the "Enabled" radio button
Click OK

Access DENIED. (and here's why)
The pagefile is a protected resource in Windows because it represents the virtual memory pool in use while Windows is running. If you could move or corrupt this resource, Windows would simply lose its mind and crash and burn.
Also, access will be restricted to this resource because it is a major security issue. If you as a user (even admin) level programmer could access the pagefile that would open Windows to password and key recovery attacks by malicious software.
NT, NT Server, XP Pro will automatically wipe the pagefile on boot and on shutdown to protect the data contents from attack.

Now I want to get the printer status, I write the code like this:
EnumPrinters(PRINTER_ENUM_LOCAL,NULL,2,NULL,0,&pcbNeeded,&pcReturned);
pPrinterEnum =(struct _PRINTER_INFO_2A *) malloc(pcbNeeded);
EnumPrinters(PRINTER_ENUM_LOCAL,NULL,2,(LPBYTE) pPrinterEnum,pcbNeeded,&pcbNeeded,&pcReturned);
for(int i = 0; i

I do not believe that status is a member of _PRINTER_INFO_2A. Use Status instead.
bluelzdwy wrote: But sadly I found It Only return zerO!
Are you saying that pcReturned is 0, or the status is 0? If the latter, that would be the expected status for a ready-to-print printer.

First thanks for your reply,I think that Status is right as a member of _PRINTER_INFO_2A,thanks a lot.
The Status is 0,you say that would be the expected status for a ready-to-print printer.However I still have some doubt,if The printer is printing ,the status is 0 too!

That would indicate a problem, as I'd expect PRINTER_STATUS_PRINTING in that scenario.
What is the value of the pPrinterName member?

First thanks for your reply again.
The value of the pPrinterName is " HP LaserJet 1022 " And I can get the member Attributes correctly. So It puzzles me if the printer don't support the member Status?

To verify this a bit further, try turning the printer off or removing the paper and see if the status is still 0. Do you have another printer that you can test with?

how to use TRACE function in console win app, if we include afxwin.h for this function then comes a lot of unresolved

TRACE is a MFC macros.
Check radio button "An application that supports MFC" on step 1 of 1 while creating console application.
|
|
|
|
|
Can we do it after app was created? it is nasty to recreate existing one completely.
if there are also similar TRACE like in STD or win libs?

see your project settings
in the C/C++ section, there might be some "MFC support" to enable
|
|
|
|
|
use api
OutputDebugString. You need to include windows.h for this.
|
|
|
|

yes it works, and in proj settings there is additional MFC libs usage combo box

We have an application developed in Windows 2000. When we run the same application on Windows XP with exactly same environment, there is a drastic increase in CPU Usage. Say if it was 15% on Windows 2000, now its 50% on Windows XP.
Application has few components communicating through DCOM and few Win32 Dlls. Any hint how can i trace which portion of code is taking too much CPU on Windows XP. Any easy to get profiling tool? any other way?
Any help would be really appreciated.

I need some artical or feedback on text with moving cursor. probably this is an irritating repetitive post for many experienced gurus here.
Text string will be retreived from dialog edit box and seen moving with the cursor in the view. As I click the left button, text should stop moving and should placed at the point. I assume ROP functions wont help here. TextOut will show the array of texts in the view. Should I keep on updating the views
as the user moves the cursor in the OnMouseMove handler to avoid that. I also
read somewhere to capture the bitmap of the text and erase it.. something liek that. I need to hav serialise support in this application. I have achived rubberband effect with lines but text seems to be hard.
Kindly help me.

You can try this:
CDC::IntersectClipRect(CurrentTextRect);
And in your OnPaint()...try not drawing the background when mouse is moving. while mouse is moving, only the updated rect should be drawn.
I am not sure of this approach. You might have to investigate.
Hope this hint helps.

I have a problem with asserts. We are implementing graphics code (OpenGL) on MFC. We finished, zipped, and emailed our assignment a month ago when it was working fine. Now, we unzip our code because we need to modify it for a new project and it gives an assertion failure at the line:
ASSERT(::IsWindow(m_hWnd));
We read the article "Assert is your friend" but upon tracing the stack, it never lead back to our code.
Can anyone help?

This kind or error checking is usually found together with code that either sends/posts messages or receives them. Since you haven't provided any info about what function this line can be found in it's impossible to tell what the problem is.
Generally an assertion of this kind indicates an error, such as a message is about to be sent but the message loop is terminated, or about to be terminated, so the message may never be handled.
I'm just guessing but maybe you are posting a message from your code that is handled in another window that is closing.
Hope this helps

It's suppose to be hard, otherwise anybody could do it!
