If you have access to that process either log it's start args or write a routine that exports them to the process you use to kill the first one.

For a general process i don't think you can do that Frown | :(

Which sql server? The type of the app does not really matter...But there are lots of ways you can connect to a sql database and lots of types of sql servers out there...you have to be more speciffic

hi all,
how to add external dependencies for a project?
I need to add a header file for the project as a external dependency. How to I add it?

Go in the project settings, C++ tab, general category and there, you have "Additional Include Directory". Put the path to the folder which contains the header file there.
Then, you can simply add the header to your project.

Another solution (much simpler) is simply to copy the header file into the folder which contains the sources of your program and add it to your project.

Hi,
Is it possible to use tests on the template typename(during compile, not in runtime)?
Something like:

template<typename T> class MyClass{<br />
...<br />
T m_Var;<br />
...<br />
void fun(){<br />
#if T==double<br />
....<br />
#else<br />
..<br />
#endif<br />
}<br />
}

Cheers,
Russell

no, because T is assigned at runtime, while #if is evaluated before the compilation

BTW, there's a mechanism called templates specializations, which allow you to design the templated class for a particuliar template parameter...

I'm not sure, are you? templates are expanded during compilation.

Elseway have you got a good link to learn something on "templates specializations".

Thanks.

hum, ok, maybe not at runtime, but at compile time at least.

unfortunately, preprocessing directives are executed BEFORE the compilation... so, no chance to do it like this

yes, I know that I can't use preprocessing directives, It was only an sintax example: I'm asking exacly on the template sintax that it can be used.

Templates ane not .NET generics.
Compiler generates all specializations for used parameters.

template<typename T> class CLS;<br />
<br />
CLS<double> aaa;<br />
CLS<vector<int> > bbb;

At compile time, this will create double and vector<int> specializations for template.

_beginthread(void( __cdecl *start_address )( void * ),unsigned stack_size, void *arglist
);

void * arglist ==> can this point to a list of arguments.

Since the thread function can have only one parameter of void * how can i achieve the
requirement is to pass set of initialisation to the thread function.

Any body help me ?

better u create a structure will all the set of variables u want to pass to thread. Now pass the pointer of this structure to the thread.

In the thread function, u can again convert the void* pointer to a pointer of your structure and use all the member inside it.

Cast any class or structure to void and recast it back from thread!
