    <p>Actualy this is the code i was interested in:</p> <pre><code>#include "windows.h" #include "mq.h" #include "tchar.h" HRESULT CreateMSMQQueue( LPWSTR wszPathName, PSECURITY_DESCRIPTOR pSecurityDescriptor, LPWSTR wszOutFormatName, DWORD *pdwOutFormatNameLength ) { // Define the maximum number of queue properties. const int NUMBEROFPROPERTIES = 2; // Define a queue property structure and the structures needed to initialize it. MQQUEUEPROPS QueueProps; MQPROPVARIANT aQueuePropVar[NUMBEROFPROPERTIES]; QUEUEPROPID aQueuePropId[NUMBEROFPROPERTIES]; HRESULT aQueueStatus[NUMBEROFPROPERTIES]; HRESULT hr = MQ_OK; // Validate the input parameters. if (wszPathName == NULL || wszOutFormatName == NULL || pdwOutFormatNameLength == NULL) { return MQ_ERROR_INVALID_PARAMETER; } DWORD cPropId = 0; aQueuePropId[cPropId] = PROPID_Q_PATHNAME; aQueuePropVar[cPropId].vt = VT_LPWSTR; aQueuePropVar[cPropId].pwszVal = wszPathName; cPropId++; WCHAR wszLabel[MQ_MAX_Q_LABEL_LEN] = L"Test Queue"; aQueuePropId[cPropId] = PROPID_Q_LABEL; aQueuePropVar[cPropId].vt = VT_LPWSTR; aQueuePropVar[cPropId].pwszVal = wszLabel; cPropId++; QueueProps.cProp = cPropId; // Number of properties QueueProps.aPropID = aQueuePropId; // IDs of the queue properties QueueProps.aPropVar = aQueuePropVar; // Values of the queue properties QueueProps.aStatus = aQueueStatus; // Pointer to the return status WCHAR wszFormatNameBuffer[256]; DWORD dwFormatNameBufferLength = sizeof(wszFormatNameBuffer)/sizeof(wszFormatNameBuffer[0]); hr = MQCreateQueue(pSecurityDescriptor, // Security descriptor &amp;QueueProps, // Address of queue property structure wszFormatNameBuffer, // Pointer to format name buffer &amp;dwFormatNameBufferLength); // Pointer to receive the queue's format name length if (hr == MQ_OK || hr == MQ_INFORMATION_PROPERTY) { if (*pdwOutFormatNameLength &gt;= dwFormatNameBufferLength) { wcsncpy_s(wszOutFormatName, *pdwOutFormatNameLength - 1, wszFormatNameBuffer, _TRUNCATE); wszOutFormatName[*pdwOutFormatNameLength - 1] = L'\0'; *pdwOutFormatNameLength = dwFormatNameBufferLength; } else { wprintf(L"The queue was created, but its format name cannot be returned.\n"); } } return hr; } </code></pre> <p>This presumably creates a queue... but there are some parts missing for this to work, that's why i need a simple example that works.</p>

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.

SQuiL has stopped working due to an internal error.

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