I just switched over from 6.0 to .NET and now i cannot access a few of my dialogs. These dialogs come up and say 'The ActiveX control "Microsoft FlexGrid Control, version 6.0" could not be instantiated because it requires a design-time license.'.
Does this mean i can't use this control without paying MS more money?!?! and if so where would i go to find out how much a license costs? i just dont get it.. it let me use it in 6.0, how is .NET more functional when it takes away my available controls!?
any insight would be much appreciated!

ThatActiveX does not exist in .NET,I think if you install VC6 at the same machine then you can use it again.

Ah, I did format before instaling .Net, thanks for the help!
by the way.. is there a different grid that they expect us to use for C++ in .NET? I saw under 'Customize toolbox' in the '.NET Framework Components' something called 'DataGrid', i see it is checked off but it isn't in my toolbox.. is this what i should be using?

I think we can't use that DataGrid in VisualC++(at least I don't know how),there are some powerfull DataGrid here in CP,I use them in my applications,If you don't know their address,I can send them for you.

I'd like to instantiate a pointer to a template class but I'm not sure if its possible.
I'd like to do something like this:
Cx<cz>* x;
x = new Cx<cz>; // or x = new Cx<cz>();
x->whatever=...;

Use 'display this message as-is (no HTML)' option - your code is screwed without that.

Thanks Tomasz,
Here is the code that I would like to do (Cx is the template class, z is some other class):
Cx<z>* x;
x = new Cx<z>();
x->whatever = ...;
|
|
|
|
|
|
This is the error i get:
error LNK2001: unresolved external symbol "public: __thiscall Cx<class z="">::Cx<class z="">(void)"
|
|
|
|
|
Sorry, here it is "as-is"
error LNK2001: unresolved external symbol "public: __thiscall x1<class z>::x1<class z>(void)"
|

This is a problem with your #include files, or a missing library. It can see the header for x1, but cannot find anything to link it to.

It seems that you have the methods of your template class defined in .cpp file. You should move them to the header.

You were right. I had the methods in a cpp file.

I tend to try things first to see if they work and ask why if they do not
std::string * pString = new std::string;
std::vector<int> * pInt = new std::vector<int>
The above compiles fine for me.

Can anyone tell me what (obvious to everyone else) piece I'm missing? The following code doesn't work when run as a service. It runs fine when run through the IDE. All it does is set a timer. The SetTimer returns a valid number, but the TimerProc callback is never hit.
Any ideas?

AFAIK services do not have message loops - and message loop is required when you want to use SetTimer, even with a callback function.
Use Sleep() or waitable timer instead of SetTimer.

Thanks for the response.
The ATL service code includes 3 methods
PreMessageLoop();
RunMessageLoop();
PostMessageLoop();
Which lead me to think (incorrectly?) that this should work. It worked with the ATL code with version 6.0, although a lot of the code that had been explicitely generated before is now contained in CAtlServiceModuleT.

First, a service is a normal Windows 32 program, and as such it has at least a system message queue (even if it doesn't use it). Each thread may also have a thread specific message queue, but the creation is deferred until it's really needed (e.g., a User or GDI function is called). The old SetTimer function makes use of window messages (it was normally used for background processing purposes back in the 16-bit days), even if you specify a callback. Because of this reason, one must get and dispatch messages when it's used.
Basically, all you need to do is to implement a Get-or-Peek/DispatchMessage-loop somewhere in your ServiceMain (or a function called from it). This is what makes the wheel go round. MFC and other framework libraries have a message loop buried way down in their private code, so you don't see it often these days, but it's still integral to Windows.
However, if the only WM-based function you're going to be using is SetTimer, there is a better solution: Waitable Timers. A waitable timer is a kernel object that can be waited on using the WaitForXObject(s) set of functions (cf. CreateWaitableTimer API), and it can be set to an absolute or relative due time. This way you can combine it with waiting on other events such as a Quit event, which is a good service design.

Thank you for responding to my query. I always appreciate it when people take the time to help.
The Run() method in AtlServiceModule calls this method
void RunMessageLoop() throw()
{
MSG msg;
while (GetMessage(&msg, 0, 0, 0) > 0)
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
and I have checked and made sure this is being hit.
As to only using a timer, my service is instantiating a COM object that uses WinSock messages (that weren't processed either). I have since written my own WinSock module that uses overlapped IO, but I am rather stubborn and would like to know WHY this code doesn't work. Timers worked fine in a service generated under VC6.
Again, I'd like to thank the people that have responded to my query. I posted the same question in a newsgroup and no one responded.
