is there a way to store 32 bit value into upper half of a 64 bits memory variable, how should this work using indirect addressing or direct addressing like fr example if I have a variable define as <pre><code>var1 QWORD 0 </code></pre> and my eax value is <code>ffffffffh</code> how can i store eax value in to upper half of var1 ? also how can i store the lower half of the same variable into 32 bits register ? <pre><code>mov DWORD PTR [var1+3], ebx </code></pre> didn't work thank in advance

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.
