particular registry key inputted by user, I am using
VB6.0 and API Call. That the information show on the

To get the information which appears in RegEdit's right pane (value names
and data) use RegEnumValue(). You can wrap RegEnumValue() in a loop after
using RegQueryInfoKey() to determine the number of values, the maximum value
name length, and the maximum value data length.

Hi
Copy and paste this the following line into your IE address bar:
http://www.google.com/search?as_q=RegQueryInfoKey&as_sitesearch=microsoft.com
(it's a Google search for RegQueryInfoKey at the microsoft.com domain)

I have no VB example. Basically, in "C", with no error control:
/* start */
HKEY hKey;
DWORD dwNumValues, dwMaxValueNameLen, dwMaxValueLen,
index, dwInitValueNameLen, dwInitValueLen;
LPSTR pszValueName;
LPBYTE pData;
/* open the registry key */
RegOpenKeyEx(HKEY_CURRENT_USER, "Environment", 0,
KEY_QUERY_VALUE, &hKey);
/* get info about what's in the key */
RegQueryInfoKey (hKey, NULL, NULL, NULL, NULL, NULL,
NULL, &dwNumValues, &dwMaxValueNameLen, &dwMaxValueLen, NULL, NULL);
/* allocate buffers that are big enough */
pszValueName = (LPSTR) malloc(1 + dwMaxValueNameLen);
pData = (LPBYTE) malloc(1 + dwMaxValueLen);
/* get the info in the registry key */
for (index = 0; index < dwNumValues; index++) {
dwInitValueNameLen = 1 + dwMaxValueNameLen;
dwInitValueLen = 1 + dwMaxValueLen;
RegEnumValue(hKey, index, pszValueName,
&dwInitValueNameLen, NULL, NULL, pData, &dwInitValueLen);
printf("%s=%s\n", pszValueName, pData);
}
/* clean up */
free(pszValueName);
free(pData);
RegCloseKey(hKey);
/* end */
Here, since the key "HKEY_CURRENT_USER\Environment" contains two values, the
example above produces the following output:
DESKTOP=e:\Users\vefatica\Desktop\
HOME=d:\home

Hi
Copy and paste the following lines into your IE address bar (it's Google
*newsgroup* searches for RegQueryInfoKey and 20RegEnumValue in different VB
groups):
