offset to stay inside the printable region of the page, MarginBounds is often lined up at offsets that don't match the user-specified margins along the edge of the page For example, on my Hewlett-Packard LaserJet 2100, the left edge of the PageBounds rectangle is actually inch in from the left edge of the page, and the top edge is 1/8 inch down from the top This affects MarginBounds, lining up the 1-inch margin I expect at 1 inches from the left edge of the page This poses a problem because neither PageBounds nor VisibleClipBounds nor any other information provided by WinForms actually tells you how much the PageBounds is offset from the edge of the paper To get the physical offsets, you must turn to interoperability with Win32 and the GetDeviceCaps function Using that, you can get the printer's physical X and Y offset from the top left and adjust the margins appropriately However, the X and Y offset is in printer coordinates, which may not be the same units as MarginBounds, so you must convert those units as well The following helper methods do all that work: [SystemRuntimeInteropServicesDllImport("gdi32dll")] static extern int GetDeviceCaps(IntPtr hdc, DeviceCapsIndex index); enum DeviceCapsIndex { PhysicalOffsetX = 112, PhysicalOffsetY = 113, } // Adjust MarginBounds rectangle when printing based // on the physical characteristics of the printer static Rectangle GetRealMarginBounds(PrintPageEventArgs e, bool preview) { if( preview ) return eMarginBounds; int cx = 0; int cy = 0; IntPtr hdc = eGraphicsGetHdc(); try { // Both of these come back as device units and are not // scaled to 1/100th of an inch cx = GetDeviceCaps(hdc, DeviceCapsIndexPhysicalOffsetX); cy = GetDeviceCaps(hdc, DeviceCapsIndexPhysicalOffsetY); } finally { eGraphicsReleaseHdc(hdc); } // Create the real margin bounds by scaling the offset // by the printer resolution and then rescaling it // back to 1/100th of an inch Rectangle marginBounds = eMarginBounds; int dpiX = (int)eGraphicsDpiX; int dpiY = (int)eGraphicsDpiY; marginBoundsOffset(-cx * 100 / dpiX , -cy * 100 / dpiY); return marginBounds; } The GetRealMarginBounds method takes preview mode into account and, when you use a real printer, adjusts MarginBounds using the physical offsets, always returning a rectangle in the same units With this in place, you can safely print inside the margins based on the edges of the paper, as you'd expect: void printDocument1_PrintPage(object sender, PrintPageEventArgs e) {.

FIGURE 14-13 In reality, you remotely control most of the server core areas of functionality As with all the remote GUI tools, if you receive an Access Denied error, solve it by performing a net use to the machine before remotely connecting The command establishes an authenticated session:

C:\Users\john>net use * \\savtstcore01virtsavilltechnet\c$ /user:virt\administrator * Type the password for \\savtstcore01virtsavilltechnet\c$: ***** Drive Z: is now connected to \\savtstcore01virtsavilltechnet\c$ The command completed successfully

A better way is to use cmdkey, which allows credentials to be set for various target systems:

This example shows running GET, PUT, POST, and DELETE requests The options hash takes all the same options that the Request constructor takes The request is run immediately and the resulting response object is returned

C:\Users\john>cmdkey /add:savtstcore01virtsavilltechnet /user:virt\administrator /pass:******** CMDKEY: Credential added successfully

gDrawString(, GetRealMarginBounds(e, thispreview)); } As an alternative to using these helper functions, the NET 11 Framework provides a property on PrintDocument called OriginAtMargins This property defaults to false, but setting it to true sets the offset of the PageBounds rectangle to be at the margin offset from the physical edge of the page, letting you print at the appropriate margins using the PageBounds rectangle However, this property doesn't have any effect in preview mode, doesn't adjust the PageBounds size, and keeps the MarginBounds as offset from the now further offset PageBounds For these reasons, I don't find it particularly useful when compared with the GetRealPageBounds and GetRealMarginBounds helper methods [ Team LiB ]

For the Windows Server 2008 release, Server Core is designed to run inthe-box functions, that is, the supported server roles and features and not additional applications

None of the major products are supported on Server Core; for example, Exchange, SharePoint, SQL, and so on For additional applications, there is some planning for the future when managed code support is added to Server Core However, there are limits to what can be added to Server Core; otherwise, it becomes a normal Windows installation Agents should be installable and supportable under Server Core, for example, backup agents, Microsoft Operations Manager (MOM), Systems Management Server (SMS) agents, and so on, which are managed via a remote administrative console function You can install antivirus agents on Server Core installations and manage them remotely For example, ForeFront runs on Server Core Virtual machine additions can be installed and they run ne; in fact, they are recommended The general rule of thumb is that agents have no shell or GUI dependencies and do not require managed code; if all these are true, the agent runs under Server Core To install additional software, execute the setup executables or manually install the MSI les using this command:

To check the installed applications, use the wmic command and the production function as shown in the following:
