SetupDiInstallClassA function

The SetupDiInstallClass function installs the ClassInstall32 section of the specified INF file.

Syntax

WINSETUPAPI BOOL SetupDiInstallClassA(
  HWND     hwndParent,
  PCSTR    InfFileName,
  DWORD    Flags,
  HSPFILEQ FileQueue
);

Parameters

hwndParent

The handle to the parent window for any user interface that is used to install this class. This parameter is optional and can be NULL.

InfFileName

A pointer to a NULL-terminated string that contains the name of the INF file that contains an INF ClassInstall32 section.

Flags

These flags control the installation process. Can be a combination of the following:

DI_NOVCP

Set this flag if FileQueue is supplied. DI_NOVCP instructs the SetupInstallFromInfSection function (described in Microsoft Windows SDK documentation) not to create a queue of its own and to use the caller-supplied queue instead. If this flag is set, files are not copied just queued.

DI_NOBROWSE

Set this flag to disable browsing if a copy operation cannot find a specified file. If the caller supplies a file queue, this flag is ignored.

DI_FORCECOPY

Set this flag to always copy files, even if they are already present on the user's computer. If the caller supplies a file queue, this flag is ignored.

DI_QUIETINSTALL

Set this flag to suppress the user interface unless absolutely necessary. For example, do not display the progress dialog. If the caller supplies a file queue, this flag is ignored.

FileQueue

If the DI_NOVCP flag is set, this parameter supplies a handle to a file queue where file operations should be queued but not committed.

Return Value

The function returns TRUE if it is successful. Otherwise, it returns FALSE and the logged error can be retrieved with a call to GetLastError.

Remarks

The caller of this function must be a member of the Administrators group.

This function is called by a class installer when it installs a device of a new device class.

To install an interface class or a device class, use SetupDiInstallClassEx.
