In what way do you need them linked?
You could try creating temporary tables to store fields from both databases.

I need to link the tables in order to run an update query on one database.
I am writing a tool that allows a user to set up mappings (fields in database1 map to fields in database2 based on certain conditions). The tool then creates an update query that joins tables from both databases and updates certain fields in database1. Since the tool may be run on different databases, I do not know in advance which tables will have to be linked.
Thanks.

Hi,
Does anyone know a good tutorial on keyboard accels, or does anyone want to give sime kind of lesson about it (like a checklist or something).
My problem is like this:
I have an app wich shows pictures, this works.
But every time a user presses the right-arrow button, the app needs to show a new picture (this is done by calling showNextPicture()).
I've already build showNextPicture(), but I can't build the link between the key and the function.
PS I'm using a dialog based app, with MFC support
Thanks for reading this!

Look at PreTranslateMessage() and TranslateMessage() in your docs. It will point you to where you can determine what key was pressed and from there what handler to call.

OK, I've read it,
But Is still don't understand what exactly I've got to do with those messages etc. can you explain that to me?

Add a menu option like ID_SHOW_NEXT, make this call your function, then map the arrow key to your menu option in the accelerator resource.

Hi there,
I've downloaded a tutorial from thecodeproject about tcp servers, and it contains the following code:
int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])<br />
{<br />
int nRetCode = 0; <br />
<br />
cout << "Press ESCAPE to terminate program\r\n";<br />
AfxBeginThread(ServerThread,0);<br />
while(_getch()!=27);<br />
<br />
return nRetCode;<br />
}
and this
<br />
UINT ServerThread(LPVOID pParam)<br />
{<br />
return 0;<br />
}<br />
I've copied the code into a neat console app with mfc functionality, but this isn't compiling.
How is this possible?

Do I hvae to define ServerThread before it's call (I'm not used to that)?
I'll try it, and if it works thank you a lot!!!

No, but you do have to declare it.

Firstly, I am sorry if this is in the wrong area but I am looking for a way to create an ActiveX control that I can include in my ASP page for using MS's TemplatePrinter functionality. Here is the site at MSDN
I need to call IOleCommandTarget:Exec, but I'm confused on how to set this up. Does anyone have experience with this?
Thanks,
Nate

It's from the help compiler. Are you making a help file? If not, you can just remove the dependency from your application.

I believe you handle that in the Project Dependencies dialog box.

Not sure, as that is the only place I've ever needed to look. Is this VS6 or VS.NET?

Hello,
I am trying to write a simple little oo windowing library for opengl (mainly a wrapper for the c based windowing code); of course i had the standard wndproc callback as a class member problem, but i found a way around that, what i did was simple enough, i made WndProc static, but that meant i couldn't get at class members and then I noticed that the last paramater of CreateWindowEx was passed as the LPARAM of your wndproc callback on WM_CREATE. So, i passed 'this':
CreateWindowEx(blah...., this);
then in WM_CREATE:
SetWindowLong(hWnd, DWL_USER, lParam);
then whenever i have a WM_* callback i acces my class through
((MyClass*)GetWindowLong(hWnd, DWL_USER))->junkMyClassPointsTo...
but CreateWindowEx is always failing, none of the paramaters are bad, the only thing i can think of is 'this' and i don't know if WndProc-WM_CREATE is called then and if it is what is giving me the problem.
if anyone could help me with this, it would be most appreciated.
thank you,
-Matt

sorry, just to add on, i have also used GWL_USERDATA instead of DWL_USER if that makes a difference, thanks

Thanks for the help, i applied all the stuff that was in that article, and it still didn't work, i also started to use WNDCLASSEX instead of WNDCLASS, but all that has done is stopped me from being able to register my class.
i type:
RegisterClassEx(&myWndClassEx);
and it throws an error, i printed the error with GetLastError, and the code is dec 87 or 0x57 and i don't know what that is or where to find the definition, this is becomming a major dilemna, any more help would be greatly appreciated

I've been working really hard on this now and i have finally figured out that my real problem is in CreateWindowEx
it is giving a return error of 6, which i found out is 'invalid handle' i think that is pointing at my hinstance, to instantiate my hinstance i call GetModuleHandle(NULL) and that is in a cpp file that is compiled into a static library, if this helps, that's great, i really need a fix for this problem, Thank you very much in advance if you can tell me what to do.

WinMain should give you an hInstance you can use.

i don't know what is happening now, i have used hInstance AS delivered by winmain, but my createwindowex is stilling failing and when i call getlasterror, i get a code of 0 which apparently means success, this is extraordinarily frustrating, thank you for your help so far, but this is just rediculousl annyoing, thank yuou for any further help
