HI All
I want to know that how to use WMI Classes using VC++,I want to extract some system information from there, but I do not know how to use that,
Better if please do provide some sample code.
Thanks & Regards.

I downloaded the mentioned project and tried to run the project but could not succeed.
Although I included all needed .lib files and header files yet I am getting two errors
1)error C2065: 'CoInitializeSecurity' : undeclared identifier
2)error C2065: 'EOAC_NONE' : undeclared identifier
However the function CoInitializeSecurity( ) is declared in "objbase.h" and I have included this file too.
So Please tell me how to remove this problem.
Please reply .
Thanks & Regards.

Hi all,
I have dll(mfc) which displays dialog with list control with some file [with path] ( .doc,.msg, ... )
When user double clicks my code opens file in maximize mode useing ShellExecuteEx. It returns me HANDLE hProcess. All works fine.
But some file like msg file are not opening in MAXIMIZE state. After looking deep into that i conclude that it is handled by MS Outlook.( means if last msg file is opend in normal window (not maximized) then my code will not open msg file maximized!!.)
So what i want is HWND from hProcess. so that i can send message to that window for maximize!!!
I have searched a lot and also applied a code. but i think my dll handles this so i m not getting required results.
//////////////////////////////////// hProcess is returned by ShellExecuteEx
WaitForInputIdle(hProcess,1000);
FILETIME lpCreationTime, lpCreationTime2;
FILETIME d1,d2,d3;
DWORD dwProcessId;
HANDLE hProc;
GetProcessTimes( hProcess, &lpCreationTime, &d1, &d2, &d3 );
HWND hTemp = ::FindWindow(NULL,NULL);
while ( hTemp != NULL )
{
if ( ::GetParent(hTemp) == NULL )
{
::GetWindowThreadProcessId(hTemp,&dwProcessId);
hProc = OpenProcess(PROCESS_QUERY_INFORMATION, 0, dwProcessId);
GetProcessTimes( hProc, &lpCreationTime2, &d1, &d2, &d3 );
CloseHandle(hProc);
if ( lpCreationTime.dwHighDateTime == lpCreationTime2.dwHighDateTime &&
lpCreationTime.dwLowDateTime == lpCreationTime2.dwLowDateTime )
{
//("Sending Message"); // Never came here
::PostMessage(hTemp,WM_SYSCOMMAND,SC_MAXIMIZE,0);
break;
}
}
hTemp = ::GetWindow(hTemp, GW_HWNDNEXT) ;
//"looping");
}
// i have also tried with EnumWindows and its proc.
Can anyone help me in getting solved my problem.
Thank in advance.
Regards
Jetli

if you have several projects in a solution that all compile to individual EXE's what do you do with version numbers?... keep them all in line with each other or have each EXE with its own independent version number?
|
|
|
|
|
I'd say that's up to the conscience of the individual church-goer. But it makes sense to me to have all different ones - why would the version number change on one part of the project, just because you updated another.

Two version numbers are within each module : File Version and Product Version.
We tend to let the File Version float depending upon the particular module.
The product versions typically are all the same for all modules of a particular product release.
This way, you can look at a DLL, for eexample, and know which version of the DLL you have and also which version of the product it was intended to work with.

thats a very good idea, thanks! I have always just automatically given them both the same version numbers, without actually thinking about why there are two different fields.

Can any body tell me how can i get client area dimensions(width & height) in millimeters?
|
|
|
|
|
mm relative to what ? The screen you're running on ? To do that, you need to know the screen resolution ( easy ) AND the screen size ( not so easy ).

Two quick queries:
1. I have programmed a little network performance monitor. It monitors a set of remote hosts over a network. It gets the CPU statistics and all gets collected at one of the remote hosts (say primary remote host, holding procValues[n][4], 4 CPU floating numbers per n remote hosts).
Now, I want to transfer this data set (double procValues[n][4]) over a TCP or UDP network connection to a local host for graphing and storing in a database tool.
I've read Beej's Networking Guide http://www.ecst.csuchico.edu/~beej/guide/net/ and going to follow his code.
However I don't know how am going to send a double[n][4] over the network efficiently without hogging the network. Is the most efficient way just converting double[n][4] into a string?
Am using a sleep(1) function to set the frequency of 1 second to read the cpu statistics.
If a sending function takes more than the frequency of "cpu statistic collecting" then am going to get lots of missed out data... no wait it wouldn't be perfectly synchronized to the exact second, it will be lagged behind. Maybe thread the network transfer so that the frequency of "cpu collecting" remains precisely every second?
What are your views?
2. How does one create/use threads in C, AND C++? Do threads differ in usage in C and C++?

Sleep(1) = 1 ms wait time. Quite difficult/impossible to reach in a Win9i/2000/XP environment without any other kernel-patch.

From my point of view it's the way, you have to pass a parameter telling the type of data you are sending or preassumed that all the data are from a certain type.
kevingpo wrote:

You'll have to separate in different threads the data treatment from the data transfer and try different thread priorities to accomplish it.
kevingpo wrote:

Depends on the implementation of C/C++ you use, but:
In C++: HANDLE CreateThread(LPSECURITY_ATTRIBUTES secAttr,
SIZE_T stackSize,
LPTHREAD_START_ROUTINE threadFunc,
LPVOID param,
DWORD flags,
LPDWORD threadID);
In C using libpthread:
int pthread_create(pthread\_t *tid, const pthread\_attr\_t *tattr,
void*(*start_routine)(void *), void *arg);

This is called homework. The idea of homework is to solidify the things the teacher was showing you in class, no doubt while you were browsing the web for pr0n. It's also a chance for you to show that you know how to do your own research.
We don't do homework here. Try to write this code yourself ( it's really pretty easy, hint: look up 'nested loops' in your C++ book ), and if you get stuck, post CODE, rather than the homework question, and SPECIFIC questions about where you are stuck. Then I'll be the first to try and help you.

int n,i,j;
int a[i][j];
int b[i][j];
int c[i][j];

 And what's the question ?????

c[i][j]=c[i][j]+(a[i][j]*b[i][j])
All these arrays are uninitialised, they have nothing in them. And unless the c[i][j] array is initialised to be all 0, this line will add the product to garbage that is there already. Given that i and j will both have their value only once, I think you need to change it to:
c[i][j]=(a[i][j]*b[i][j])
and also, if you have < in your code, there's a check box below the text window that you need to check so they don't get regarded as HTML. That's why your code is not all visible.

Have you seen the sheer number of posts Christian makes? Much less posts in EVERY board? I think he has a direct line to the SQL servers. I have often wondered if Christian isn’t bob in disguise.

I've seen him answer to MANY posts, but sometimes the mass of other posters here are a little bit faster.

No, especially if he posts while I am asleep
But what I was trying to say was not 'I will be the one who answers you', rather, 'although I've been rude this time, I will be very happy to help you if you ask a specific question and try to do your own work first.'
