MASM in VisualStudio 2010

First step:

Create an empty project in Visual C++:

![0_13161448202etA.gif][]

Second, right-click project in solutionexplorer, Build customizations, tick "masm",

![0_1316144863PFJG.gif][]

![0_13161448928WQR.gif][]

Then tap the right of mouse, select Add

![0_1316144930s0E0.gif][]

Now, select C++ File(.cpp), enter the sourcefile name with .asm as extend file name.

![0_13161449586eU9.gif][]  
Tap right of mouse, choose Properties:

![0_13161449844vFf.gif][]

Expand the entry under ConfigurationProperties. Then expand the entry named Microsoft Macro Assembler.

![0_1316145015aU4M.gif][]

Notice that the Include Paths option hasbeen set to the x:\\file directory\\include directory.

In this example, include directory isc:\\Irvine.

Next, select the **Listing File** entry, also in theMicrosoft Macro Assembler group. Notice that the Assembled Code Listing Fileentry (shown below) has been assigned a macro name (starting with $) thatidentifies the name of the source input file, with a file extension of .lst.So, if your program were named main.asm, the listing file would be namedmain.lst:

Find the Linker entry under **ConfigurationProperties**. Select the**Input** entry, and notice that two filenameshave been added to the**Additional Dependencies** entry. The **user32.lib**file is a standard MS-Windows file. The**irvine32.lib** file is the linklibrary file supplied with this book. There must be at least one spaceseparating the file names:

![0_1316145130ppAJ.gif][]

Next, select **Linker** underConfiguration Properties, and then select**General**. The **AdditionalLibrary Directories** option equals**c:\\Irvine**, so the linker can findthe Irvine32.lib library file(you also can copy irvine32.lib to .../VC/LIB direcotry, so this would needn't to be done):

![0_1316145174HC0c.gif][]

Select **Linker** under the **ConfigurationProperties** and select**Debugging**. Notice that the **Generate DebugInfo** option is set to**Yes:**

**![0_1316145209j0Mz.gif][]**

Select **System** under the **Linker**entry. Notice that the SubSystem option has been set to**Console**:

![0_13161452674oCn.gif][]

We use the Console settingbecause it is easy for assembly language programs to write output to a textconsole (Command) window. This is the window you see when running cmd.exe fromthe Start > Run menu in Windows.

Click the OK button to close theProject Property Pages window.
