Devmode Structure Printer Driver
ExtDeviceMode function • 1/18/2018 • 2 minutes to read In this article The ExtDeviceMode function is provided only for compatibility with 16-bit applications. Aerofly Fs Keygen For Mac here. Soul Togetherness 2001 Rar there. Printer drivers without this requirement should instead use the DocumentProperties function, which is described in the Microsoft Windows SDK documentation. The ExtDeviceMode function retrieves or modifies printer initialization information for a given graphics driver, or displays a driver-supplied printer-configuration property sheet for the specified printer.
Syntax LONG ExtDeviceMode( _In_opt_ HWND hWnd, _In_opt_ HANDLE hInst, _Inout_ LPDEVMODEA pDevModeOutput, _In_opt_ LPSTR pDeviceName, _In_opt_ LPSTR pPort, _In_opt_ LPDEVMODEA pDevModeInput, _In_opt_ LPSTR pProfile, DWORD fMode ); Parameters hWnd Handle to the parent window for the printer-configuration property sheet. HInst Not used. Handle to the module instance of the device driver.
PDevModeOutput Pointer to the DEVMODE structure that receives the printer configuration data supplied in the buffer pointed to by the pDevModeInput parameter. PDeviceName Pointer to a NULL-terminated string that contains the name of the device for which the printer configuration property sheet is displayed. PPort Pointer to a NULL-terminated string that contains the name of the port to which the device is connected, such as LPT1. PDevModeInput Pointer to the DEVMODE structure that the operating system uses to initialize the property sheet fields. This parameter is used only if the DM_IN_BUFFER flag is set in the fMode parameter. If DM_IN_BUFFER is not set, the operating system uses the printer's default DEVMODE structure.
PProfile Not used. Pointer to a NULL-terminated string that contains the name of the initialization file in which initialization information is recorded and read from. FMode Specifies the operations that the function performs. If this parameter is zero, the ExtDeviceMode function returns the number of bytes required by the printer driver's DEVMODE structure. Otherwise, this parameter can be set to one or more of the following flag values. Flag Meaning DM_COPY Write the driver's current settings to the DEVMODE structure pointed to by the pDevModeOutput parameter. The calling application must allocate a buffer large enough to contain the information.
DEVMODE Structure. Free Afl Premiership 2005 Ps2 Manual Programs. The DEVMODE structure has the following form. A printer driver supports only those members that are appropriate for the printer technology.
If this flag is not set, pDevModeOutput can be NULL. DM_IN_BUFFER Merge the printer driver's current print settings with the settings in the DEVMODE structure pointed to by the pDevModeInput parameter. This occurs before prompting, copying, or updating.
The function updates the structure only for those members specified by the DEVMODE structure's dmFields member. In cases of conflict during the merge, the settings in the DEVMODE structure pointed to by pDevModeInput override the printer driver's current print settings. DM_UPDATE Display a property sheet to allow the user to modify printer properties, and then write the driver's current 'per user' settings to the user's hive in the registry. Return Value If the wMode parameter is zero, the function returns the size, in bytes, of the DEVMODE structure required to contain the printer-driver initialization data. Note that this value can be larger than the size of a DEVMODE structure if the printer driver appends private data to the structure.
