How to change screen orientation of each screen individually from C++ or C#? Having dual screen display configuration in mirror mode. Intel Graphics card is installed on the machine. I tried EnumDisplaySettings function and DeviceMode structure. However, it only works in extended mode. If I try to change orientation by this function in mirror mode both screens are set to the same orientation. Maybe there is a way to change this settings through Intel driver SDK or any other native windows 7 functionality? UPDATE 1: Here is the code I tried with CCD API. It still rotates both displays =( <pre><code>UINT32 PathArraySize = 0; UINT32 ModeArraySize = 0; DISPLAYCONFIG_PATH_INFO* PathArray; DISPLAYCONFIG_MODE_INFO* ModeArray; DISPLAYCONFIG_TOPOLOGY_ID CurrentTopology; SetDisplayConfig(0,NULL,0,NULL,SDC_TOPOLOGY_CLONE|SDC_APPLY); //set to clone mode GetDisplayConfigBufferSizes(QDC_ALL_PATHS, &PathArraySize, &ModeArraySize); PathArray = (DISPLAYCONFIG_PATH_INFO*)malloc(PathArraySize * sizeof(DISPLAYCONFIG_PATH_INFO)); memset(PathArray, 0, PathArraySize * sizeof(DISPLAYCONFIG_PATH_INFO)); ModeArray = (DISPLAYCONFIG_MODE_INFO*)malloc(ModeArraySize * sizeof(DISPLAYCONFIG_MODE_INFO)); memset(ModeArray, 0, ModeArraySize * sizeof(DISPLAYCONFIG_MODE_INFO)); LONG ret = QueryDisplayConfig(QDC_DATABASE_CURRENT,&PathArraySize, PathArray, &ModeArraySize, ModeArray, &CurrentTopology); PathArray++; PathArray->targetInfo.rotation = DISPLAYCONFIG_ROTATION_ROTATE180; //set Second display rotated 180 PathArray--; SetDisplayConfig(PathArraySize,PathArray,ModeArraySize,ModeArray, SDC_APPLY | SDC_SAVE_TO_DATABASE | SDC_ALLOW_CHANGES | SDC_USE_SUPPLIED_DISPLAY_CONFIG); //apply rotation free(PathArray); free(ModeArray); </code></pre>

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.
