Can you create a WindowsService[^]

Somethings seem HARD to do, until we know how to do them.

Thanks for your reply.

But can you please tell me under which registry key this service is stored.
Suppose my exe name is ABC.exe and i want to create service for this exe to run in background.

As you send me link on that page they have given key
HKEY-LOCAL_MACHINE\SYSTEM\SERVICES
but can you please tell me under this key where i have to put my exe or where I have to create my new key to run my service in background for ABC.exe

Thanks again!!!!

   It is not really enough to take a normal EXE and throw it into the Services entry in the Registry. A Windows Service is a special type of executable and needs to be written as such. A Windows Service supports control functionality, and the SCM, which manages Services, handles things like authentication and dependencies.

   You should create a new Windows Service project. You should be able to use much of the boilerplate/wizard code as-is and just add your functionality to it.

   Peace!

Hi all,

What am I doing wrong?

// Header File
class TCP32CLIENT
{
public:

	TCP32CLIENT_API void MsgBoxThreadProc(void *var);
};

//CPP File
void TCP32CLIENT::MsgBoxThreadProc(void *var)
{
 ...
}

bool TCP32CLIENT::setApplicationParameters()
{
		int val = 1;
		HANDLE handle;
		handle = (HANDLE) _beginthread( &TCP32CLIENT::MsgBoxThreadProc,0,&val);
		WaitForSingleObject(handle,7000);
...
}

Error: Error 6 error C2664: '_beginthread' : cannot convert parameter 1 from 'void (__thiscall TCP32CLIENT::* )(void *)' to 'void (__cdecl *)(void *)' c:\documents and settings\baileyr\my documents\tcpip project\tcp32client\tcp32client.cpp 166

Even if I do this:

...
handle = (HANDLE) _beginthread( MsgBoxThreadProc,0,&val);
...

I receive the following error:
Error 6 error C3867: 'TCP32CLIENT::MsgBoxThreadProc': function call missing argument list; use '&TCP32CLIENT::MsgBoxThreadProc' to create a pointer to member c:\documents and settings\baileyr\my documents\tcpip project\tcp32client\tcp32client.cpp 166

Many Thanx

It is because global functions and member functions of a class don't have the same prototype. For the member functions, there is an implicit parameter that is passed which is the 'this' parameter (identifies to which instance of the class it belongs to).

So, that's why your compiler complains. A solution is to use a static function: in that case, the member function doesn't belong to a specific instance of the class but is shared across all instances. In that case, the 'this' parameter is not passed but that also means that you can only access static members of your class in your static function.

Not Responding Message

Hi,

we have developed one application in which we can download new updated exe from the ftp.

We got success in that process but while downloading new file taskmanager window shows the message Not Responding instead of running.

Can anyone tell me what's wrong going on in my application?

Cedric Moonen5-Mar-07 22:39

If the code is in the main thread, then your application won't be able to respond to GUI events (thus the 'Not Responding' message and the window will stay blank). You need to start your download in a separate thread for that.

I understand fully. Cedric has explained why and offered a solution. Did you implement it?

Check out SendMessageTimeout(hWnd, WM_NULL, ..., SMTO_ABORTIFHUNG, ...) for more.

   The "Not Responding" message appears if your application does not pump messages for a certain amount of time (I believe it is 5 seconds), and then a user tries to interact with it by activating it, clicking on it, etc.

   The background thread suggestion(s) are the way to go, I just wanted you to understand exactly why that message appears.

   Peace!

Hi James,

Thanks for giving me reply but as per you told that I have to pump message continuously to keep running my application So, How can i pump message in background to do this?

I have used Spawnl() function in my application to replace my older exe to new one.

I hope you will understand the problem which I have faced.

Thanks again!!!!

You do not pump messages in the background, you download the updated EXE in the background. You do this by creating a background thread and having it do the FTP transaction, and your primary thread continues to pump messages and operate normally.

Peace!

I have a window where 3D diagrams are drawn.When the window is maximized the
diagram appears correctly.But when it is minimized or if we change the size of the window the diagram is getting clipped.

Sometimes when the diagram which is clipped originally is displayed without clipping when we change the size.

I need code for resizing the diagram(clipped and unclipped) according to the window size.

plz help... Sigh | :sigh:

Thanks
