Hi Steven,
Thank you,
As per client requirement I supposed to convert custom actions from C# to
C++.
The below is C# customaction which I used previously,
[CustomAction]
public static ActionResult SetPROP(Session session)
{
try
{
DriveInfo di = new DriveInfo("D");
if (di.DriveType.ToString().Equals("Fixed") && (di.IsReady))
{
session["PROP1"] = "D:\\";
session["PROP2"] = "D:";
}
else
{
session["PROP1"] = "C:\\";
session["PROP2"] = "C:";
}
}
catch (Exception ex)
{
}
return ActionResult.Success;
}
My Properies
<Property Id="PROP1" Value="D:\" />
<Property Id="PROP2" Value="D:" />
Customaction
<CustomAction Id="SetPROP" BinaryKey="CustomActions.dll" DllEntry="SetPROP"
Execute="immediate" Return="ignore" />
In ExecuteSeq
<Custom Action="SetPROP" After="ValidateProductID"/>
I would like to know how to check disk drives in C++
