This function is called before installation begins. It is used for operations such as checking the version of an application during reinstallation or seeing whether a dependent application is present.

Install_Init is developer-written, using the specified prototype for compatibility.

codeINSTALL_INITInstall_Init(HWNDhwndParent,BOOLfFirstCall,BOOLfPreviouslyInstalled,LPCTSTRpszInstallDir);

Parameters

  • hwndParent
    [in] Handle to the parent window.
  • fFirstCall
    [in] When set TRUE, indicates this is the first time this function is being called.
  • fPreviouslyInstalled
    [in] When set TRUE, indicates the current application is already installed.
  • pszInstallDir
    [in] Pointer to null-terminated string with the name of the user-selected installation directory.

Return Values

Value Description
codeINSTALL_INIT_CONTINUE Continue installation.
codeINSTALL_INIT_CANCEL Cancel installation.

Remarks

Install_Init can be called multiple times with different strings for pszInstallDir; for example, when the current directory does not have enough room. ISVs should do "first time" processing when fFirstCall is TRUE and be aware that subsequent calls to Install_Init may result in different string values for pszInstallDir.

The Install_Init function is part of the application's setup and uninstall program, Setup.dll.

Requirements

OS Versions: Windows CE 2.0 and later.
Header: Ce_setup.h.
