Sorry for the ignorence, but suppose I called GetProcessTimes() and converted the FILETIME arg' to SYSTEMTIME (using FileTimeToSystemTime(),
how do I compute (and which parameter is the significant) the CPU usage of a process per second?
truthfully yours, Me.

SYSTEMTIME is not a good choice to calculate relative times.
To compute CPU usage per second, just call GetProcessTimes every second and compute the difference of the paramaters lpKernelTime (time spent inside system routines) and lpUserTime (time spent inside user code). To subtract two FILETIMEs, copy them to ULARGE_INTEGERs and subtract these (more info about FILETIME arithmetic on the online documentation about FILETIME).

There are two simple ways:
1. Enumerating processes. You can use the following classes to enumarate processes on both NT/2000 and Win9x. http://www.codeproject.com/threads/enumprocess.asp
2. You can use FindWindow API to find Visual C++ window. You can also give the class name as a parameter to be sure that the window found is Visual C++ Window.
Hope this helps.
Kind regards

I am working on an MFC MDI application. I'd like to have the document title (in the app's title bar) display an asterisk at the end when the document has been changed. When the document is saved, the asterisk disappears. MS Visual Studio's text editor has this capability.
Any suggestions on how to add this capability?

With AfxGetMainWnd you can get The main window Handle then you can use GetWindowText for read the Title and add a Asterisk when the docuement is changed using SetWindowText for write the new title. But Warning you can fill the Title with several asterisks, you need a control like a variable for this...

CDocument provides some methods to maintain the "changed and unsaved" state, namely IsModified and SetModifiedFlag. I guess the best solution is to override SetModifiedFlag (assuming your app is using this method consistently) and change there the document's title accordingly using SetTitle.

Uh, i've tried a few dozen times to write a function that sees if a certain item of a list is also in another list but it just wouldn't work. And there's also a second difficulty, but i'll explain by giving the information needed:
First of all, its not really a list, but its several strings i can get after eachother. I have to parse a line of text wich uses '#' as a seperator like this:
cookoo#woowoo#blabla#weewee
this is the string(mystring) and i parse it with AfxExtractSubString(...) like this:
int index=0;
while(AfxExtractSubString(Item, LPCTSTR(mystring), index++, '#')
{
if(Item!="")
// Item is a good string so...
}
}
This is the same way for the two lists/strings only that the second string/list contains less or as much substrings as the first string/list and the strings the second string/list contains are always in the first one. BUT! it is possible that certain string(s) in the second one have '[' in front of it and ']' behind like this:
weewee#[woowoo]#gaga#blabla
i need to see this and make a difference between strings that have [] and strings that dont.
So the main goal is to see if any items from the first string/list are in the second one and if they have [] or not.
Can anyone help me with this as my brain seems to lack stamina for this.

Try something like this:
int index=0;
int index2;
CString mystring;
CString csSecondString;
while(AfxExtractSubString(Item, LPCTSTR(mystring), index++, '#')
{
if(Item!="")
{
int n = csSecondString.Find(Item);
if (n > -1)
{
if (n>0)
{
if (csSecondString[n-1] == "[" &&
csSecondString[n+Item.GetLength()] == "]")
{
}
}
}
}
}
Hope this helps,
Bill

I was browsing the internet when i came across a free utility that enables you to make your pc accessible using a static name, such as www.123-321.com, and wondered if anyone knew how to make that.

Using any user-selectable domain name? Now that would be impressive...

maybe they have a pre-registered list of say around 500 domains

Besides, 500 domain names would go quick...!

Anyone out there that has used Outlook can understand this: When you add an address to the "To..." edit control (when writing a new email message), once the address is "recognized", it becomes underlined, but also becomes an object. Meaning, it is only selectable as a whole item, you are no longer able to select part of the recognized address.
I have been unable to accurately duplicate this functionality. After staring at Spy++ for a while, I believe that the address text is eventually taken from the control (WM_GETTEXT), the OLE interface and Event Mask are accessed (EM_GETOLEINTERFACE, EM_GETEVENTMASK, EM_SETEVENTMASK), the Text Mode is accessed (EM_SETTEXTMODE, EM_GETTEXTMODE), the address is resolved/recognized, removed from the control (EM_SETSEL and WM_SETTEXT), and I believe address gets converted to some kind of visible COM object, because I never see a message that directly replaces the address text. But I am at a loss as to how to get started writing such an object.
Any thoughts (based in reality)? Or does anyone know how that REALLY works, that can tell me that I am WAY off base, and can tell/show me how it is done?
Peace!

I believe the thing you see in the address edit control is just a piece of text. The event handling is what keeps you from editing or selecting part of it.
I do not, however, have any special inside knowledge of how this is implemented.
Hope this helps,
Bill

I never thought of it that way... But I will see about trying that approach. Thanks for the idea.
The EM_GETOLEINTERFACE message is what confuses me. AFAICT, it is only sent at the point of "conversion", and it (IRichEditOle) contains a method called "ConvertObject", which sounded just about right... 
Peace!

I wrote a program with CFormViews containing several controls (CButtons, CEdit...)
On certain events I enable or disable them using:
GetDlgItem(IDC_WHATEVER)->EnableWindow(TRUE);
or
GetDlgItem(IDC_WHATEVER)->EnableWindow(FALSE);
it works perfectly fine in Win 98 but wouldn't work in Win 2000,
Controls just refuse to become gray and deactivated
I've got ServicePack 5 installed and I've tried it on several Computers but with no success.
What could be wrong??
Thanks in advance, Semlo

Are you sure the error is there? Maybe some other obscure problem is causing this. try debugging and trace through the valid code areas. If still unsuccessful, try posting some code snippets

Thanks Nish, it was indeed a stupid programming mistake which Win98 doesn't care about but win 2000 does..

Hi,
I created an InProcServer(ToolBand.dll) on my Windows NT Wkts which works fine for NT Server4.0, Win98, 2K, and Me. This doesn't get installed on the setup of Win95 running IE5. I get error message "This function is only valid in Win32 mode". There were some "Ex" Registry API used in DllRegiserServer(). I've replaced it with normal API's i mean without "Ex", but the problem remains same. I get same error message with RegSetValue(..) API. Is there any compatibility issue?
It seems that Windows 95 is not pure win32. Hey Any comments? Why its so ironical behaviour? Should I need to build this application on VC++ running on Windows 95? I there any registry key or service to get some Win32 services on Win95.
I'm fed-up with this behaviour. Help me with any comments.

Yep. Win95/98/ME do not support the complete Win32 API. Much of the Unicode-versions of functions are flat-out missing, others are partially implemented (and will return the error you mention), and a few are implemented fully for COM use.
It sounds like you are using an NT-or-greater-only function in your code. Take another look at the bottom of the MSDN help pages for information on what platforms support what functions.
You can also put
<br />
#define _WIN32_WINDOWS = 0x0410<br />
#define WINVER = 0x0400<br />
- Before all other includes in your StdAfx.h file to help check what functions you are using. (Look up those identifiers in MSDN for more information.)
Peace!

Hi,
It is a surprise knowledge that Win95 is not pure Win32 OS. Thanks for this information. Hey anyway I defined those system-variables but it didn't helped me out. I've verified all the API's and its documented for Win95 and later so as far documentation is concern there is no issue of lacking support. But Do you believe in M$ Documents  ? Personally I never, I've many bad experiences with false commitment and wrong information in documentation from M$. The main surprise for me is error in Registry API call, RegCreate..., which i've used in many of my softwares and was not creating any problem in those. But it stucked up in this development and with previously used API's but those were normal application and this is COM.... Grrrrrr....
Let me notify if you have another suggession on this.
Regards,
--Sumit

Please specify exactly how you are calling the failing function, what parameters you are passing in to it, and the total length of any string parameters.

As "Collaboration/Testing" is a section that doesn't receive much attention, I'm taking the liberty to insert here a little ad for a post of mine I've just sent there (click here to go). It requests a little help from you all about a weird behavior in Windows 2000 that seems to me to be a bug and is driving me nuts.

with the below code all i see is a scrambled image. i used the same code in watcom c++ and it seemed to work ok. I am now using msvc++.
i am not sure if i am doing something wrong or if i have to change the functions to microsoft standards.
HDC ScanImageDC, hdc, Oldhdc;
HBITMAP ImageBitmap, OldImageBitmap;
HRGN hrgn;
hdc = GetDC(NULL);
Oldhdc = hdc;
hrgn = CreateRectRgn(0, 0, 800, 600);
SelectObject(hdc, hrgn);
FillRgn(hdc, hrgn, (HBRUSH) CreateSolidBrush(RGB(255, 255, 255)));
DeleteObject(hrgn);
ImageBitmap = CreateBitmap(imgwth,imghth, 1, 1, Image);
ScanImageDC = CreateCompatibleDC(hdc);
SetBkMode(ScanImageDC, OPAQUE);
OldImageBitmap = SelectBitmap(ScanImageDC, ImageBitmap);
int xxx= SetStretchBltMode(hdc,STRETCH_HALFTONE);
StretchBlt(hdc, 0, 0, 800, 600, ScanImageDC, 0, 0,imgwth,imghth, SRCCOPY);
SelectBitmap(ScanImageDC, OldImageBitmap);
DeleteDC(ScanImageDC);
DeleteObject(ImageBitmap);
