Problem to increment key value
now i want to increment key value at run-time, i am trying but nothing solved this problem yet.
e.g. when i run program the key-value is 1, and i want that when i run this program again the key-value should be 2...
plz help me for this problem
Simple solution -- each time the program starts it updates the key value with a new value. Call RegQueryValue() to get the current value, increment the counter, then RegSetKeyValue() to update it.
Call these functions in the order listed. You will have to do error checking to insure they succeed.
RegOpenKeyEx()
RegQueryValue()
RegSetKeyValue()
RegCloseKey()
Thanx for reply,
But i solve this problem myself before your reply...
And i also solve my problem through RgOpenKeyEx() as u said....
But Thanx for reply because your posts are useful for me & others...
