Install_Init (Windows CE 5.0)
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.
