ExpandEnvironmentStrings
The ExpandEnvironmentStrings function expands environment-variable strings and replaces them with their
defined values.
DWORD ExpandEnvironmentStrings(
LPCTSTR lpSrc,
| // pointer to string with environment variables
| LPTSTR lpDst,
| // pointer to string with expanded environment variables
| DWORD nSize
| // maximum characters in expanded string
| );
|
|
Parameters
lpSrc
Points to a null-terminated string that might contain references to
environment-variable strings of the form:
%variableName%
For each such reference, the %variableName% portion is replaced with the current value of that environment variable.
The replacement rules are the same as those used by the command interpreter.
Case is ignored when looking up the environment-variable name. If the name is
not found, the %variableName% portion is left undisturbed.
lpDst
Points to a buffer to receive a copy of the source buffer, after all
environment-variable name substitutions have been performed.
nSize
Specifies the maximum number of characters that can be stored in the buffer
pointed to by the lpDst parameter, including the terminating null character.
Return Values
If the function succeeds, the return value is the number of characters stored
in the destination buffer. If the number of characters is greater than the size
of the destination buffer, the return value is the size of the buffer required
to hold the expanded strings.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
