| Q.: Can I adjust the connection timeout value and the connection and data buffer sizes? |
A.: Yes all of these are done through a registry entry so that the end user of your application may adjust these too if necessary.
The parameters used to control the behavior of the Distinct FTP-32 library are stored under the following registry path.
HKEY_LOCAL_MACHINE\SOFTWARE\Distinct\DLLS\FTP32
Timeout REG_DWORD number of seconds
Specifies the default timeout in seconds used for the FTP connection. This is the timeout value used for various network operations. The default value is 20 seconds. If you are using a serial connection you may want to increase this to 40.
BufferSize REG_DWORD number of bytes
Specifies the default buffer size in bytes used for data transfer. The default value is 32768 bytes and the permitted range is from 1024 to 32768 bytes.
CtrlBuffer REG_DWORD number of bytes
Specifies the default buffer size in bytes used for the control connection. The default value is 1024 bytes and the permitted range is 128 to 4096 bytes.

| Q.: Can I write an FTP client that only allows users to download files without allowing them to upload files. |
A.: Yes, you can write a client that only allows GET - However, the restriction is valid only when this FTP client is used. That is, if the user used a differnet FTP application and tries to PUT a file - it would work unless you restrict it from the server end.
