    <p>I want to simulate keyboard presses in C++ using <b>SendInput</b>, while single buttons work, trying to send keys simultaneously (shortcuts) doesn't work.</p> <p>I tried everything, but nothing works, if I send <b>VK_LWIN</b> alone it shows up, but couldn't combine keys simultaneously.</p> <p><b>here's my code:</b></p> <pre><code>#include &lt;windows.h&gt; #include &lt;stdlib.h&gt; #include &lt;stdio.h&gt; void setInput(INPUT * inp,uint index, WORD keycode,BOOL kUp); void showRun(); int main(void) { showRun(); return 0; } void setInput(INPUT * inp,uint index, WORD keycode,BOOL kUp) { inp[index].type = INPUT_KEYBOARD; inp[index].ki.wVk = keycode; inp[index].ki.wScan = MapVirtualKey(keycode, 0); inp[index].ki.time = 0; inp[index].ki.dwExtraInfo = 0; if (kUp == 1) { inp[index].ki.dwFlags = KEYEVENTF_KEYUP | KEYEVENTF_EXTENDEDKEY; }else { inp[index].ki.dwFlags = 0 | KEYEVENTF_EXTENDEDKEY; } } //this doesn't do anything void showRun() { INPUT *inp = (INPUT*) malloc(sizeof(INPUT) * 4); memset(inp,0,sizeof(INPUT)); setInput(inp,0,VK_LWIN,0); setInput(inp,1,VK_RBUTTON,0); setInput(inp,2,VK_RBUTTON,1); setInput(inp,3,VK_LWIN,1); SendInput(4,inp,sizeof(INPUT)); free(inp); } </code></pre> <p><b>while this works fine:</b></p> <pre><code>void showStart() { INPUT *inp = (INPUT*) malloc(sizeof(INPUT) * 2); memset(inp,0,sizeof(INPUT)); setInput(inp,0,VK_LWIN,0); setInput(inp,1,VK_LWIN,1); SendInput(2,inp,sizeof(INPUT)); free(inp); } </code></pre> <p>Thanks in advance for any tip.</p>

    2. COSide note, since you're sending a fixed amount of keys, there's no need to dynamically allocate your inputs, just make your array local.

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).
