    <p>I'm working on a pre-existing codebase and I'm looking to have the user type any 1-2 digits followed by the enter key at any time during the code being run and pass that number to a function. Currently, user input is handled like so:</p> <pre><code>LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { int wmId, wmEvent; switch (message) { case WM_KEYDOWN: Engine::GetInstance()-&gt;GetInput()-&gt;GetKeyboard()-&gt;SetKeyPressed(static_cast&lt;int&gt;(wParam)); break; //snip </code></pre> <p>Now, I'm not sure of a few things,</p> <ul> <li><p>a) Why would the keypressed be passed as an integer rather than a character? </p></li> <li><p>b) What would be the result of "F1" being sent in this case aaand</p></li> <li><p>c) How can I use this to read in a 1-2 digit number and pass that only when enter is pressed?</p></li> </ul>

    1. COIs there a reason you need to do this using WM_KEYDOWN? For cooked keyboard input, WM_CHAR would be a better choice--it'll handle numeric keypads and other input weirdness.

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.
