After calling DevEnum(), you are able to retrieve the names of all printing devices installed on the system with this method. With each call you retrieve one entry.
method string VPE.GetDevEntry(
long Index
)
long Index
must be in the range between 0 and the value returned DevEnum() - 1
Returns:
The name of the device specified by "index". If index is out of range, an empty string ("") will be returned.
Remarks:
This method works only correctly, if you called DevEnum() before.
Example:
long i, count
string s
count = DevEnum() - 1 // initialize enumeration
for i = 0 to count
s = DevEntry(i)
MessageBox(s) // show each available device in a separate message box
next i
Note:
Do not call DevEnum() repeatedly, because each time VPE will query all printers from the system.
Wrong Example:
long i
string s
for i = 0 to DevEnum() - 1
s = DevEntry(i)
MessageBox(s) // show each available device in a separate message box
next i
