This member of RFIO Object is supported on iOS, Windows Mobile, Windows CE, Palm, and DOS.
The PushScreen method saves the current displayed screen directly to an RF device’s non-volatile memory for later restoration.
VB
bStatus = object.PushScreen (pszScreen)
VC++
HRESULT hr = object->PushScreen(LPCTSTR pszScreen, BOOL *bStatus);
Return Value
|
bStatus |
The status of the function returned as Boolean True or False values. Use the RFGetLastError method to return the error value. |
Parameters
|
pszScreen |
The file name in which the currently displayed screen will be saved. |
Remarks
Use the PullScreen Method to restore a previously saved screen file if you wish to remove the screen file from the RF device’s memory. Use the RestoreScreen Method to restore a screen without removing it from the RF device’s memory. When used in conjunction, PushScreen and PullScreen or RestoreScreen allow you to temporarily interrupt a displayed screen within your application, then restore the screen to its original state.This allows for faster display when re-using screens.
It is recommended that you clear the output queue immediately before using the PushScreen method.
Example
See the PullScreen Method.
