It's part of the C run-time library source. This is not installed by default with Visual C++ 6. If installed, it is in \Program Files\Microsoft Visual Studio\VC98\CRT\SRC. If not installed, just re-run the installer and install the C run-time source as an additional component. For Visual C++ 7.x, it's in \Program Files\Microsoft Visual Studio .NET\Vc7\crt\src or \Program Files\Microsoft Visual Studio .NET 2003\Vc7\crt\src, depending which version you have installed. I can't remember if it's installed as part of the default setup or if you have to drill into the install options to select it. Brad

You have a few options available. As the structure exists in the application class (CMyApp), you can create a member function that returns the address of this structure. Now, if this method is called from inside CMyDoc, the document has the address of the structure, and can operate on it freely, providing that both objects reside on the same thread. If they do not, things get more complicated. Alternatively, taking an advanced step from the section above, you can create a structure into CMyDoc as well, then get a pointer from CMyApp and use memcpy to copy the structure data from CMyApp to CMyDoc. Now, CMyDoc contains a copy of the structure. The previous posted created an example piece to show you how to access the application object at run-time. Use this method to call the function that returns the structure address. -Antti Keskinen ---------------------------------------------- The definition of impossible is strictly dependant on what we think is possible.
