    <p>I'm making a program that allows users to customize hotkeys and make them perform specific functions.</p> <p>The first function that I have made moves the cursor to a specific set of coordinates within the game window. It does this by finding the client area then adding the set coordinates and then moving the cursor there. However, it appears that each time SetCursorPos is called, it moves twice: first to the correct spot, the to (0,0). I'm not sure what's causing this, and I've spent hours googling and debugging to no avail. Everything works correctly except that it moves twice. I'm using Windows 8 and compiling with Code::Blocks.</p> <p>The script outputs what coordinates it should be moving too before the mouse moves and after. They should be the same. It also outputs "key down" when the hotkey is pressed down and "key up" when it is released.</p> <p>Pressing F1 will cause the mouse to move.</p> <pre><code>#include &lt;iostream&gt; #include &lt;windows.h&gt; using namespace std; class macro{ public: int x, y, w, h; HWND hWnd; HWND get_hWnd(){ hWnd = FindWindow(NULL,"Untitled - Notepad"); return hWnd; } void get_Pos(){ RECT pos; GetClientRect(hWnd,(LPRECT)&amp;pos); ClientToScreen(hWnd,(LPPOINT)&amp;pos.left); ClientToScreen(hWnd,(LPPOINT)&amp;pos.right); w = pos.right; h = pos.bottom; x = pos.left; y = pos.top; } void activate(){ ShowWindow(hWnd, SW_SHOWMAXIMIZED); } void initialize(){ get_hWnd(); get_Pos(); } void mousemove(int rx, int ry){ get_Pos(); cout &lt;&lt; "Pre-move: " &lt;&lt; rx+x &lt;&lt; "," &lt;&lt; ry+y &lt;&lt; endl; SetCursorPos(rx + x,ry + y); cout &lt;&lt; "Post-move: " &lt;&lt; rx+x &lt;&lt; "," &lt;&lt; ry+y &lt;&lt; endl; } }macro; int main(){ macro.initialize(); bool loop = true; bool action_complete = true; int prev = 0; int curr = 0; bool key_state; // True if down, false if up. while(loop){ if(GetAsyncKeyState(0x70)){ curr = 1; } else{ curr = 0; } if (prev != curr){ if(curr){ key_state = true; macro.mousemove(100,100); cout &lt;&lt; "key down" &lt;&lt; endl; Sleep(100); } else{ key_state = false; cout &lt;&lt; "key up" &lt;&lt; endl; Sleep(100); } prev = curr; } } } </code></pre>

    1. COYour code looks like it will move the mouse cursor only once. You probably have some system wide settings on the mouse like "Automatically move pointer to the default button in a dialog" set and this could be causing the other move.

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.
