Thank you, Mike!
I didn't realise that. I'm still new with Visual C++ and MFC (about 2 weeks) and it takes some time to get used to them.
I took another aproach to the problem, but I'm sure that what you told me would work. I'm gonna give it a try!

Hello
I need your help in DLL side loading processes. I made a DLL (MFC shared DLL) with dynamic link option. I made the settings correctly as I suppose. I am sending the code alongwith this as an attachment. But when I call the symbol "initialize" (in the DLL) in an application it is showing "undefined symbol" error. Could you please help me find out a solution for this? I am also sending the code where the symbol from the DLL should be called.
Regards,
Sreekanth Muralidharan.

use FTP? The WinInet library (wininet.lib) has a comprehensive set of functions to do just that (see MSDN). You will have to run a FTP server on your server box though - you can either use IIS or a dedicated application such as Bulletproof FTP.

Well,
You would have to learn WEBDAV, assuming that this html extension is installed on your server and useable by the web server.
Otherwise, you'll have to do it using FTP or get a listener on the webserver.
If its not your own server (i.e.: like a free web server on the net) then you might need to be imaginative. For example, if they have a web interface to update pages, then you make a web page browser/form filler/etc .. so that it does the work for you. But its a time consuming process.

Hi,
Im pretty new at the whole c++ thing and have attempted to modify an app that requires the controlling of services. The start, stop, pause, continue etc work fine but the thing is that the person who first wrote the app has enabled multiple services to be able to be controlled from the one string of arguments. Eg. start service name service name service name which will call on the start method to start the 3 specified services. I guess my question is how do i limit this to only allowing 1 service to be passed. The code is below for clarification. The first method is the parse command line method followed by the int main();
boolean ParseCommandLine(int argc, TCHAR* argv[], DWORD &dwAction, DWORD &dwTimeout, Services &services)
{
if (lstrcmpi( argv[1], TEXT("/?") ) == 0)
{
printf("\nSCM controls Windows services, formerly know as NT services.\n");
printf("\nSCM start/stop/pause/resume/keepalive/status 'Service Name' [/k] [Timeout in");
printf("\nseconds]\n");
printf("\n start Starts the desired service if service is in a stopped state.");
printf("\n stop Stops the desired service.");
printf("\n pause Pauses the desired service if the service is running.");
printf("\n resume Resumes the service to a running state from a paused state.");
printf("\n keepalive Keeps the service running regardless of the state it is in.");
printf("\n status Returns the current state of the service as an error level.");
printf("\n ServiceName The name of the service to be controlled. This name has to be");
printf(" the services' name and not the display name.");
printf("\n/k (optional) Passing the /k command performs a kill function on the");
printf("\n service if the desired state or function called is not ");
printf("\n reached within a specified time, determined by the timeout");
printf(" specified.");
printf("\nTimeout in seconds Time in which to perform the specified action. The timeout");
printf("\n<optional> range is specified between 1 - 3600 seconds. Any timeout");
printf("\n outside of this range will result in the command not being");
printf(" executed.\n\n");
}
else if (argc < 3)
{ printf("\nNot enough arguments.\nArgument sequence is:\n\nSCM start/stop/pause/resume/status 'service name' [/k] [timeout in seconds].\n\n");
return false;
}
else if (lstrcmpi( argv[1], TEXT("start") ) == 0 )
dwAction = SERVICE_START;
else if ( argc > 1 && lstrcmpi( argv[1], TEXT("stop") ) == 0 )
dwAction = SERVICE_CONTROL_STOP;
else if ( argc > 1 && lstrcmpi( argv[1], TEXT("pause") ) == 0 )
dwAction = SERVICE_CONTROL_PAUSE;
else if ( argc > 1 && lstrcmpi( argv[1], TEXT("resume") ) == 0 )
dwAction = SERVICE_CONTROL_CONTINUE;
else if ( argc > 1 && lstrcmpi( argv[1], TEXT("keepalive") ) == 0 )

dwAction = 80;
}

{
dwAction = 99;
QuerySvc(hSCM, argv[2]);
}

{

{

return false;
}
// Check that argument is only digits
for (int c = 0; c < _tcslen(argv[i+1]); c++)
{
if (!iswdigit(*argv[i+1]))
{
printf("\nTimeout specified is not a number\n");
printf("\nArgument sequence is:\nSCM start/stop/pause/resume/keepalive/status 'service name' [/k] [timeout in seconds].\n");

PrintError(GetLastError());
}

}
}
}
return 0;
}
Any help would be greatly appreciated. Thanks

For a very quick fix try commenting out this line of code:
for (int i = 2; i < argc; i++)
{
string sz = argv[i];
if (sz.length() <= 0) continue;
if (sz[0] == _T('/')) break;
//comment out the line below
//services.push_back(sz);
}
you should still optimize some part though.
hope this helps for the meantime.

It does help but unfortunately commenting out that line will cause none of the command line functions to execute - it just terminates. So not good for the app if it cant actually control anything.

Its due when wrote:
...how do i limit this to only allowing 1 service to be passed.
Look at the argc variable passed to ParseCommandLine().

What is it in particular that im looking at. The variable itslef has to exist as a count for the number of arguments passed to the command line, right?

The argc parameter. I'm assuming it's the same argc that was passed to the main() function.

Hello,
I want to share the data between Dll to DLL. That is I am having two Dll and one Application program. I know how to share data between a Dll and Application program as given below.
#pragma data_seg(".myseg")
int share=0;
#pragma data_seg()
by defining in the "DEF" like
SECTIONS
.myseg Read Write Shared
but by this method I am not able to share a Data between DLL to DLL
Please suggest me the solution.

avoid using MFC in COM srevers as it has thread affinity. wot does this means exactly . !!!
Thanks in advance.
|
|
|
|
|
|
can you tell me wot thread affinity means, in a single sentence also fine.
|
|
|
|
|
most of the MFC objects internally uses local thread storage extensively.
so they are bound to their owner thread, and not supposed to be shared with other threads.
this is why MFC has thread affinity.
It's not a bug, it's an undocumented feature.

|
|
|
|
To have thread affinity means to be "bound to the thread". Therefore the object can only be used safely from that thread.
In the case of MFC, some objects are bound to threads through MFCs use of Thread Local Storage. Attempting to use the object in a thread other than the thread it is bound to will result in errors since the thread local storage data is not present.
Hope that helps?

Kindly tell me how do i register its .exe file as windows service.
What command will be used and what steps ll be needed.
reply soon,
Thanks

CreateService is used to create a service object as well as add the service to the SCM database.
SC_HANDLE CreateService(
SC_HANDLE hSCManager,
LPCTSTR lpServiceName,
LPCTSTR lpDisplayName,
DWORD dwDesiredAccess,
DWORD dwServiceType,
DWORD dwStartType,
DWORD dwErrorControl,
LPCTSTR lpBinaryPathName,
LPCTSTR lpLoadOrderGroup,
LPDWORD lpdwTagId,
LPCTSTR lpDependencies,
LPCTSTR lpServiceStartName,
LPCTSTR lpPassword
);
