Thanks for reply. Now How would i know about the number of accounts with administrative rights. I want to create another if there exist only one admin account.
BTW, thanks for previous reply. i hope for positive reply for this question also

Thanks a lot again. I tried to use NetUserEnum. But it gives me the information about every account created on a machine.
My requirement is to get only number of accounts and its information which are having administrator rights.
Thanks in advance. Please help me out.
Thanks

#1) There is nothing like GetNumberOfAccounts(). However, it should be easy to count the number of accounts yourself with the information NetUserEnum() provides.
#2) For finding if an account has administrative rights, you can use NetUserGetInfo(), which I suggested in my previous post itself.

A bunch of thanks. I got a clue from your answer and also found solution for getting number of admin account from NetGetUserInfo.
Thanks a lot again.

Hello to all,
I am having three questions in MFC,
1)In MDI (Multiple Document Interface) application whenever we minimize or maximize application's main outer window then which function gets called which indicates that window is maximized or minimized and where it is?
2)Is there any flag value or any other value, through which I can know the current state of my application's main window means I can know that whether my main window is in maximized state or in minimized state? and if there is such a value then how can we get that value and where?
3)Suppose my application is running and application's main outer window is in maximized state and now if I opened another non MFC application(e.g. Notepad or MS-Word) without minimizing my MFC application then on screen, that non MFC application will overcome my MFC application and now if I want to see my MFC application once again then I have to click on icon of my MFC application which is on taskbar,so as to display my MFC application once again on screen.Now my question is that, in such situation, programatically (through coding) can we check whether our MFC application is being displayed on screen or not? I mean is there any way through which we can know that whether our MFC application is being displayed on screen or not?
It is urgent so can anybody help me please?.It is really urgent
Thanks and Regards,
Anay

When ever your window is maximized or minimized, the window will get WM_SYSCOMMAND message. so handle the WM_SYSCOMMAND message of the MainFrame class to know when your window is being maximized or minimized.

From the wParam of WM_SYSCOMMAND, you can know that. check MSDN[^] for more details.
AnayKulkarni wrote: which we can know that whether our MFC application is being displayed on screen or not?
I guess your requirment is to know whether the current window is active window or not. In that case you can handle the WM_ACTIVATEAPP[^] message in your main frame class and track activation and inactivation of your application...

Yes,it worked.Thanks a lot for your valuable help.Thank you very much.

Your window will receive a WM_WINDOWPOSCHANGING message.

Hi All,
My exceptions are to write and read data simultaneously.As data is written it should be read by another process.For this I am using the PIPE implementation.
I wrote the following code snippet for this but it is not working
Please let know where i am wrong
Thanks
HANDLE rHandle, wHandle ;
DWORD dw ;
DWORD dw1 ;
void WriteData(LPVOID)
{
char wBuff[512];
strcpy(wBuff, "HELLO world this program for reading the pipe\n ") ;
for( ; ; )
{
Sleep(1);
if(WriteFile(wHandle, wBuff, strlen(wBuff), &dw, NULL))
{
printf("Total %d byts written\n", dw);
}
else
{
printf("Could not write the buffer Last error:%d\n ", GetLastError());
break;
}
}
}
void ReadData(LPVOID)
{
char wBuff[512];
int i =0 ;
strcpy(wBuff, "HELLO world this program for reading the pipe\n ") ;
for( ; ; )
{
Sleep(1);
if(ReadFile(rHandle, wBuff, strlen(wBuff), &dw1, NULL))
{
printf("Total %d byts read\n", dw1 );
}
else
{
printf("Could not read the buffer Last error:%d\n ", GetLastError());
break;
}
}
}
void main()
{
HANDLE aThread;
DWORD ThreadID;
int i;
if(CreatePipe( &rHandle, &wHandle, NULL, 0))
{
CreateThread( NULL, 0, (LPTHREAD_START_ROUTINE) WriteData, NULL, 0, &ThreadID);
CreateThread( NULL, 0, (LPTHREAD_START_ROUTINE) ReadData, NULL, 0, &ThreadID);
}
}

You're using the pipe in threads, not processes, may be that's the problem

Thanks for the input.
Can't i use the PIPE in the same process ?
|
|
|
|

You certainly can. But if it's in the same process, why use a pipe at all? You can use something much simpler, even a raw array, if you like, so long as you're careful about synchronization[^].

Thanks for the info,
Actually , I have used the array in my sample program there i have to synchronize it.
Now i want to check that how to use the pipe and will it signal to read Thread automatically as it is written.
Please provide any link or sample so i could implement it in the same process.
Thanks

There is an article about pipes in the Code Project here[^]. Check out the Intra-process Communication part of the article, that's what you need. Hope that helps.

Hi,
I have application that performs some administrative activities such as hooking mouse, keyboard and some application APIs. It is running properly in Admin user i.e. the user is having full Administrative priviledges with UAC enabled and some Admin Approval mode policies enabled. But this activities will not work if I run the same application in standard user profile with with UAC enabled and some Admin Approval mode policies enabled. However, standard user will not have full admin priviledges to perform these activities.
I would like to do the same activities in standard user profile. Please let me know is there any way to implement this in VC++.
Thanks
SNI

If your process requires elevated privileges, then it
needs to run elevated, right?
A standard user is going to need credentials to get past UAC AFAIK.
UAC wouldn't be effective if you could code your way around it.

Yes u r right and I'm running this application with admin credentials i.e. built in administrator account. even though it is not loading driver in standard user profile if UAC is enabled.

Do you just need the app to run elevated?
If so you can do that with a manifest entry.

yes we can do that using manifest file but problem with manifest file is that, if we configure that process should run with admin credentials then it will always prompt user to provide admin PASSWORD. Please correct me if i'm wrong.
Also I tried this with sample program where i'm providing requestLevel = 'requireAdministrator' but it is not working. If you know proper way to do it pls let me know. while compiling program it gives warning that requestPriviledge tag is bypasses or not consider.
