Mr.KarstenK,
iam already go through that topic that what u are specified to me and i know abt serial communication.but what iam asking is communication b/w system and Modem.
i have to prepare that code in VC++
like when we press the button "connect".it will conncet 2 modem after 2 rings.
thanQ,
kp.

|

And where are you stuck exactly ? Do you know the protocol you need to use to communicate with the modem (probably AT commands) ?
|
|
|
|

Mr.Moonen,
thanks for reply,
i know all the Hayes AT Commandswhich are the communication protocols through hyperterminal 2 modem.
but iam enable to instantiate a connection to modem in MFC.
how can i start,by inserting an activex control..shall it work
regards,
kp

I would start by thoroughly reading modem-related articles such as this and this.

Hi All,
How do i convert LPARAM to CComBstr?
Sunil
|
|
|
|
|
Use itoa() to convert long/int to char* and append this to CcomBSTR as in the given sample code:
LPARAM temp = 90;
CComBSTR t;
char* buf= new char[5];
buf = itoa(temp,buf,10);
t.Append(buf);
Cheers!!

When I try to shutdown remote pc Using the followind code it gives me the error of Access denied. Can anyone tell why this is happening.
HANDLE tokenHandle = INVALID_HANDLE_VALUE;
TOKEN_PRIVILEGES newTokenPrivileges;
TOKEN_PRIVILEGES oldTokenPrivileges;
DWORD oldTokenPrivilegeSize = 0;
LUID newLuid;
DWORD dError;
WCHAR CompName[] = L"node129xp.radixweb.local";
OpenProcessToken(GetCurrentProcess(), (TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY), &tokenHandle);
LookupPrivilegeValue(CompName, SE_REMOTE_SHUTDOWN_NAME, &newLuid);
newTokenPrivileges.PrivilegeCount = 1;
memcpy(&newTokenPrivileges.Privileges[0].Luid, &newLuid, sizeof(LUID));
newTokenPrivileges.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(tokenHandle, FALSE, &newTokenPrivileges, sizeof(TOKEN_PRIVILEGES), &oldTokenPrivileges, &oldTokenPrivilegeSize);
if(!InitiateSystemShutdown(CompName, L"System is shutting down in 30 seconds", 30, TRUE, TRUE))
dError = GetLastError();
|
|
|
|

Does it fail on all machines or just node129xp.radixweb.local?
What did LookupPrivilegeValue() and AdjustTokenPrivileges() return? If either of those fail, it obviously does no good to call LookupPrivilegeValue().

I am checking return value after each and every WinAPI call and it doesn't fail after LookupPrivilegeValue and AdjustTokenPrivileges but fails on InitiateSystemShutdown when I use
DWORD dError = GetLastError();
Its Shows dError = 5. i.e. Access Denied.
If I give My Computer Name instead of anyone else's from my network it is working. But If I give any other Machines's name it gives above Error.

What happens if you use shutdown -m \\node129xp.radixweb.local -t 30 from a command prompt?
I tried your code on the two machines on my desk and it works as expected. The key difference may be that I belong to the Administrators group.

I am using win2000 Service Pack 4. And When tried the command you have told me it shows the following error 
'SHUTDOWN' is not recognized as an internal or external command,
operable program or batch file.
I am not able to figureout what is the problem.Do have any Idea ?

Sorry, it must be a Windows XP thing.

If I did, don't you reckon I would have offered it by now? Other than your own, can you shut down any PC on your network?

Hi,
I tried the same code to shutdown other computers in the LAN.But it is showing the same Error Access is denied.

I think I have the administrative rights for the computer I am working. but not sure. If you can tell me how to check will be helpful to answer correctly.

Which the other (remote) computer couldn't care less about.

Then What do you think what should be the problem.I have tried to google the thing but getting the same line of code,that is not working in my case.

Hello,
I have a dialog without resources which works fine.In a class derived from CDialog I have a variable of type DLGTemplate.This variable has default x,y,cx,cy values set in the constructor.
But I want to increase the height and width of the dialog box in accordance with the number of windows controls added to the dialog box.I am adding windows controls in the OnCreate() function of Dialog class like this.
CRect Rect(10,10,100,100);
CComboBox* Combo = new CComboBox;
Combo->Create(WS_VISIBLE | WS_CHILD |CBS_SORT, Rect, this, ID);
How do I find the relation between the above Rect's coordinates and the coordinates of the dialog box?
I tried MapDialogRect but I don't understand what exactly is done there?
Please help.
Thanks
Prithaa

The co-ordinates specified in the control's Create() call are specified in the parent's (your dialogue's) CLIENT co-ordinates.
'Client' co-ords have their (0, 0) at the top-left of the space *within* any border and title bar the dialogue has. If it has no border and no title bar, then this is the same as the top-left of the full dialogue.
If you want to know how far the control is from the top-left of yoour dialogue and you have a title bar and / or border, then you need to get the dialogues 'window' rect, and the control's 'window' rect, and then you can calculate the offset.
Note, though, that if you ask a control for its client rect, it gives you co-ordinates relative to *its*own* client area, not its parent.
If you ask a control or window for its 'window' rect, it gicves you co-ords relative to *the*screen's* top-left.
So, to get the offset from a dialogue's client arrea to a control's top-left, do this:
CRect rctControl ;
MyControl.GetWindowRect(&rctControl);
// It's relative to top-left of screen.
MyDlg.ScreenToClient(&rctControl);
// Now, relative to top-left of dlg's client area.
To get it relative to the full dlg's top-left (ignoring title bar and border):
CRect rctControl ;
MyControl.GetWindowRect(&rctControl);
// It's relative to top-left of screen.
CRect rctDlg ;
MyDlg.GetWindowRect(&rctDlg);
rctControl.OffsetRect(rctDlg.left - rctControl.left,
rctDlg.top - rctControl.top);
// Now, relative to top-left of dlg's full area.
|

If you know your client area size, and you want to calculate the window
size that will give you that client area size, you can use:
CWnd::CalcWindowRect() (MFC)
or
AdjustWindowRect()/AdjustWindowRectEx() (Win32)

Hi All,
I am writing an application which checks LPT signal for doing something. My code looks like:
void LPTThread()
{
while (1)
{
if (ReadLPT(pinX) = signal level Y) {do something;}
}
//pin is one of pin of LPT port
//signal level of each pin is 0 or 1 at a time
}
This loop cause the CPU usage always 100%, is there any way to prevent it? Can we catch this change by any event handler, it mean when a change occurs at LPT or, this event handler will be called?
Thank you for your help.
