Hi, All.
=======
I have an API console application.
Does anyone know if I can and how to change/set the icon ?

If you need to support many Windows flavours then give this a try;
TCHAR szTitle [ 1024 ];
::GetConsoleTitle ( szTitle, 1024 );
HWND hWnd = ::FindWindow ( NULL, szTitle );
if ( NULL != hWnd ) {
HICON hIcon = ::LoadIcon ( ::GetModuleHandle ( NULL ),
MAKEINTRESOURCE ( IDI_MY_ICON ) );
if ( NULL != hIcon ) {
::SendMessage ( hWnd, WM_SETICON, FALSE,
reinterpret_cast<LPARAM>( hIcon ) );
}
}
Ofcourse you'll want to play nice and free the icon resource when your done, but you get the idea.
If your using Win2K you should take a look at GetConsoleWindow function and use it to replace the FindWindow code listed above (because depending on the console's title the above code might no always work as expected).

Almost forgot...
Because I'm using a console application I prefer not using resources,
I think I would like to load it from a file.
I'm not checking the MSDN, 'cause... I'm lazy I guess.;)
If you can help me, ... Thanks.

::LoadImage is what you want.
HANDLE LoadImage(
HINSTANCE hinst,
| LPCTSTR lpszName,
UINT uType, = IMAGE_ICON
int cxDesired, = 0
int cyDesired, = 0
UINT fuLoad ); = LR_LOADFROMFILE | LR_DEFAULTSIZE

From MSDN:
Note Because the Win32 message LB_ITEMFROMPOINT works only with Windows 95, ItemFromPoint, which wraps the Win32 message also works only with Windows 95.
I am using Win98 and it works fine, does this function work with NT/2000/XP and if not, what is the alternative?

Works fine under Windows 2000. The possibility that a message would be removed ( thus breaking software for newer OS's ) seems odd to me. I reckon you're probably pretty safe to use it.

I am trying to find the current directory of my application on a HPC2000 operating system using Visual C++ 3.0 Embedded. The function GetCurrentDirectory does not seem to exist for the embedded environment. Anybody solve this problem, or have any hints to get me started.

Not sure if this is what you're after, but it will get you the dir that your exe is in. Ive tested this on a PocketPC device. I dont have any HPC's available atm.
TCHAR szModule[512];
DWORD dwResult = ::GetModuleFileName(AfxGetApp()->m_hInstance, szModule, 512);
if(dwResult == 0) return;
CString strInstallDir = szModule;
int pos = strInstallDir.ReverseFind('\\');
strInstallDir = strInstallDir.Left(pos+1);
|
|
|
|
|
Ooops... the last part was from a non-unicode project.
int pos = strInstallDir.ReverseFind(L'\\');
will fix it.

As we know, when we click left button of mouse on the menu item of menu bar, it will mapping it with it's handling function. But how could i how could do the same thing with click right button of mouse??

Why would you want to confuse your users in this way ?

I don't think it's possible since WM_COMMAND is fired only for regular left-button clicks. Christian is right though, why do something so weird?

How can I launch a new child frame from a inherited CView class??
|
|
|
|
|
Do you mean a new instance of a CView derived class in an MDI app, or do you mean a new child window that is the child of a CView derived class ?

The idea is this:
Now that I've got the communication between my CMouse and CHtlm2View classes, I want that based in some information that my CMouse class give to my View class, launch a new chils windows with another html page displayed on it. I dont' know if this can be done from the View? Or shoul I launch it from the CMainframe class?? Anyway I don't how to do it....

Your document template ( which is in CMainframe ) has the method CreateNewFrame, which takes a pointer to the document associated with the view and returns a CFrameWnd*. Then you need to call InitialFrameUpdate on the template also, passing in the frame pointer and doc pointer. The best place for this is your document, because you can use theApp global variable to access the template, and 'this' for the document.

Can't use theApp variable. Doesn't recognize it!!
|

try putting an extern statement in, if it's an MFC app wizard generated app, then it is there. You can get the app as easily with AfxGetApp() if you need it.

Hi,
I know how to use the PSI.DLL (was it?) for checking a process' memory usage etc. But how can I get information about each process' CPU usage? I want to include a CPU usage bar in my software to display how much CPU that software is using.
Hints anyone?
|

WMI provides that information. I don't remember the specific profider. something like WIN32_Process. There are some examples of exactly what you are trying to do. I saw them while looking for some other WMI code. Just do some searches on google, code guru etc. You'll find them.
Hope this helps,
Bill

I managed to find PDH.DLL which uses either WMI or Registry data. I can get CPU usage from here, MSDN also contains docs on this DLL. Only problem now is I can't understand how to get process CPU usage, which functions, do I use Counters etc, how do I set them up?
An example would be perfect.

I don't know which method your asking about...
With WMI, get all instances of Win_32_Processor provider and query the LoadPercentage. This will return an average over 1 second.
Here is the class I ended up using in my project utilizing the PDH.dll. I create an instance of the class for each cpu on the system, query each and take an average, when I want to know the answer.
Class definition:
#ifndef __CPUUSAGE_CLASS__
#define __CPUUSAGE_CLASS__
#include<pdh.h>
class CCPUUsage {
public:
CCPUUsage();
~CCPUUsage();
#pragma message("CCPUUsage")
BOOL Init(LONG nMinTicksBetweenSamples = 1000, int iProcessor = 0);
int GetUsage(PBOOL pfNewSample = NULL);
private:
HQUERY m_hQuery;
HCOUNTER m_hCounter;
int m_nMinTicksBetweenSamples;
DWORD m_msLastTick;
int m_nLastSampledCPUUsage;
};
#endif // __CPUUSAGE_CLASS__
Class implementation:
CCPUUsage::CCPUUsage()
{
}
CCPUUsage::~CCPUUsage()
{
PdhCloseQuery(m_hQuery);
}
BOOL CCPUUsage::Init(LONG nMinTicksBetweenSamples, int iProcessor)
{
m_nMinTicksBetweenSamples = nMinTicksBetweenSamples;
m_msLastTick = 0;
// m_msLastTick = GetTickCount();
PDH_STATUS pdhs = PdhOpenQuery(NULL, 0, &m_hQuery);
CString csPath;
csPath.Format("\\Processor(%d)\\%% processor time", iProcessor);
pdhs = PdhAddCounter(m_hQuery,
TEXT(csPath), 0, &m_hCounter);
CString strDiag;
strDiag.Format("CCPUUsage::Init, pdhs = %x, Processor = %d",pdhs,iProcessor);
TRACEX(strDiag);
m_nLastSampledCPUUsage = 0;
return (pdhs == 0);
}
int CCPUUsage::GetUsage(PBOOL pfNewSample ) {
BOOL fNewSample;
if (pfNewSample == NULL)
pfNewSample = &fNewSample;
*pfNewSample = FALSE;
DWORD msCurrentTick = GetTickCount();
DWORD msLastTick = m_msLastTick;
if (msCurrentTick < msLastTick) {
// Wrap around, always sample
*pfNewSample = TRUE;
} else {
if ((msLastTick + m_nMinTicksBetweenSamples) < msCurrentTick) {
// It's been long since the last sample, get a new sample
*pfNewSample = TRUE;
}
}
CString szdiag;
if (*pfNewSample) {
if ((DWORD) InterlockedExchange((PLONG) &m_msLastTick, msCurrentTick) == msLastTick) {
PdhCollectQueryData(m_hQuery);
PDH_FMT_COUNTERVALUE pdhfcv;
PDH_STATUS stat = PdhGetFormattedCounterValue(m_hCounter, PDH_FMT_LONG, NULL, &pdhfcv);
szdiag.Format("GetStatus::PdhGetFormattedCounterValue returned %x, CStatus = %x",
stat,pdhfcv.CStatus);
TRACEX(szdiag);
if (pdhfcv.CStatus != 0) return -1; // This indicate erro (CPU doesn't exist for example)
m_nLastSampledCPUUsage = pdhfcv.longValue;
} else {
*pfNewSample = FALSE;
}
}
return(m_nLastSampledCPUUsage);
}
I create an object then call its Init method. For some reason, I don't understand, the PdhOpenQuery call returns success even if the CPU doesn't exist!! So I make an additional call to GetUsage, which returns -1 if there the requested processor doesn't exist.
Usage:
CArray<CCPUUsage*, CCPUUsage *> cpus;
int nCPUCount = 0;
while (TRUE)
cpus[nCPUCount] = new CCPUUSAge();
cpus[nCPUCount].Init(50,nCPUCount);
if (cpus[nCPUCount].GetUsage == -1) break;
nCPUCount++
}
Hope this helps
Bill
