    <p>In result to my post <strong>Can I use int21h on windows xp to print things?</strong>, I have seen an article about using Windows API's and in this article was a reference to using the _WriteConsole@4 API to print a message to the console. The article is at <a href="http://cs.lmu.edu/~ray/notes/x86assembly/" rel="nofollow noreferrer">http://cs.lmu.edu/~ray/notes/x86assembly/</a>. </p> <p>Here is my code so far:</p> <pre><code>.386P .model flat extern _ExitProcess@4:near extern _GetStdHandle@4:near extern _WriteConsoleA@20:near public _go .data msg byte 'if you get this, it worked.', 10 handle dword ? written dword ? .code start: _go: push -11 call _GetStdHandle@4 mov handle, eax push 0 push offset written push 13 push offset msg push handle call _WriteConsoleA@20 push 0 call _ExitProcess@4 end start </code></pre> <p>I am using this syntax to compile the code: ML:</p> <pre><code>ml (the file is called test.asm) test.asm /c </code></pre> <p>Link:</p> <pre><code>link test.obj C:\masm32\lib\kernel32.lib /SUBSYSTEM:CONSOLE /entry:go </code></pre> <p>I have gotten it to compile and link, but when I run the .exe that is produced, it does absolutely nothing, not even an error return. The console is just black. Why is this?</p> <p>Any help would be greatly appreciated. And to the users of this forum, I apologize for bombarding stackoverflow.com every day, it is just that I have very few resources to learn with.</p> <p>Thanks in advance,</p> <p>Progrmr</p>

    1. COWorks for me on Visual Studio 2010 (10.00.40219.01), though you should adjust the `13` to be the real length of `msg`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
