The purpose of this article is to share with you about how to realize the screen transfer function under WM. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Under WM, users can often turn the screen, but this can also be achieved through code, here is a tested code.

Int ChangeDisplaySettings () {DEVMODE DevMode; int RotationAngles = 0; int CurrentAngle = 0; int NewAngle = 0; / / Check for rotation support by getting the rotation angles supported. Memset (& DevMode, 0, sizeof (DevMode)); DevMode.dmSize = sizeof (DevMode); DevMode.dmFields = DM_DISPLAYQUERYORIENTATION; if (DISP_CHANGE_SUCCESSFUL = = ChangeDisplaySettingsEx (NULL, & DevMode, NULL, CDS_TEST, NULL)) {RotationAngles = DevMode.dmDisplayOrientation;} else {RotationAngles =-1;} / / Get the current rotation angle. Memset (& DevMode, 0, sizeof (DevMode)); DevMode.dmSize = sizeof (DevMode); DevMode.dmFields = DM_DISPLAYORIENTATION; if (DISP_CHANGE_SUCCESSFUL = = ChangeDisplaySettingsEx (NULL, & DevMode, NULL, CDS_TEST, NULL)) {CurrentAngle = DevMode.dmDisplayOrientation;} else {CurrentAngle =-1;} / Rotate to the "next" angle. If ((CurrentAngle > = 0) & & (RotationAngles > = 0)) {NewAngle = CurrentAngle; do {NewAngle
