<div class="content wysiwyg-content">
I want to call a windows function - 
 
BOOL AddPrinterDriver( 
&nbsp; LPTSTR pName, &nbsp; &nbsp; &nbsp; &nbsp;// server name 
&nbsp; DWORD Level, &nbsp; &nbsp; &nbsp; &nbsp; // driver information level 
&nbsp; LPBYTE pDriverInfo &nbsp; // driver information buffer 
); 
 
from my program. 
It requires 3rd argument as type LPBYTE which is a pointer to structure 
containing printer driver information.The structure is: 
 
typedef struct _DRIVER_INFO_3 { 
&nbsp; DWORD &nbsp;cVersion; 
&nbsp; LPTSTR pName; 
&nbsp; LPTSTR pEnvironment; 
&nbsp; LPTSTR pDriverPath; 
&nbsp; LPTSTR pDataFile; 
&nbsp; LPTSTR pConfigFile; 
&nbsp; LPTSTR pHelpFile; 
&nbsp; LPTSTR pDependentFiles; 
&nbsp; LPTSTR pMonitorName; 
&nbsp; LPTSTR pDefaultDataType; 
} DRIVER_INFO_3, *PDRIVER_INFO_3; 
 
How do i declare a pointer to this structure so that i can populate 
structure members and then how to pass this pointer to AddPrinterDriver function?

How to declare LPBYTE type Pointer to a structure

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
