Update for HTTP and LAN

[pramod]

Hello Friends,

when i m trying to create an script which is used to update from both the HTTP and LAN server. But when use the wizard it work only for one either HTTP or LAN. Please show me the steps to create script for both HTTP and LAN.

Thanks,

[jassing]

you mean you get some files from the LAN and some files from HTTP?

You're going to have to do some scripting -- but it's easy once you get the hang of it..

Since I don't know what is at your line 56 -- I can't even begin to help you there; but you're trying to use nil as a table; which doesn't work.
as for your other error; it sounds like you are trying to access a url on a server that doesn't exist...

Thanks for reply....

I'd like to set the location of my TrueUpdate servers by reading from the registry.
I've looked on the TU2 help, but wasn't able to find it.

I'd like to set the location of my TrueUpdate servers by reading from the registry.

You can't insert new information in TrueUpdate's server list table in runtime. All servers have to be informed before you build the updater, if you want to use TrueUpdate.GetServerFile().

You may, however, download the server files by yourself if they are to be retrieved from a location not on the TU server list, and like jassing said - some scripting is required. Here is my suggestion:

1. For example, you could retrieve the IP address from where to download the server files from an *.INI file with INIFile.GetValue(), or from the registry with Registry.GetValue() if it was inserted there.
2. After you have the current address from where to check for an update, build the new URL and use HTTP.Download() to retrieve the three files (*.ts1, *.ts2 and *.ts3) from the remote server (or from the LAN) and store them locally in the same (temporary) folder.
3. Then, after you have managed to fetch the files, use TrueUpdate.LoadServerFile() to load the *.ts1 file with the correct encryption key.
4. Finally, if the file was loaded without error, use TrueUpdate.RunScript() to perform the steps necessary to update the installation.

You should be able to find examples for each step in the help file.

I want to set the TrueUpdate Server path from the registry in client script (download server script). i'll try to get the servername but it throw error "The requested URL was not found on the server". Can you show me example.

Didn't you post this the other day? Can you pull up the url on another computer? What url is the client trying to get? did you load the files to the server as specified in the docs?

Hello Jassing,

yes i have load the file on the server.

and the client script for OnStart is this

function GetServerFileCallback(BytesDownloaded, FileSize, TransferRate, SecondsLeft, EstimatedTimeRemaining, ServerStatusMessage, tableClientUpdateInfo)

-- Did the user click Cancel?
if(screen_globals.Cancelled) then
-- Tell the GetServerFile action to abort
return false;
end


local Downloading = TrueUpdate.GetLocalizedString("MSG_UPDATE_INFORMAT ION");

-- Set appropriate messages if we're updating the TrueUpdate Client
if(tableClientUpdateInfo) then
-- What part of the Client are we updating?
if(tableClientUpdateInfo.UpdateType == 0) then
Downloading = TrueUpdate.GetLocalizedString("MSG_UPDATE_EXECUTAB LE");
else
Downloading = TrueUpdate.GetLocalizedString("MSG_UPDATE_DATA");
end
end

-- Reset the progress bar if we've started downloading something different
if((screen_globals.Downloading == nil) or (Downloading ~= screen_globals.Downloading)) then

DlgProgressBar.SetPos(CTRL_PROGRESS_BAR_01, 0);

screen_globals.Downloading = Downloading;
end

-- Update the status text to show what we're downloading
DlgStaticText.SetProperties(CTRL_STATICTEXT_LABEL_ 01, {Text=TrueUpdate.GetLocalizedString("MSG_DOWNLOADI NG")..": "..Downloading.." "..TrueUpdate.GetLocalizedString("MSG_FROM").. " "..TrueUpdate.GetLocalizedString("MSG_SERVER_NUMBE R").." "..screen_globals.CurrentServerIndex});

-- Calculate the percentage that has been downloaded so far
local PercentComplete = 0;
if(FileSize > 0) then
PercentComplete = (BytesDownloaded/FileSize) * 100;
end

-- Update the progress bar
DlgProgressBar.SetPos(CTRL_PROGRESS_BAR_01, PercentComplete);

-- Update the status text
if(ServerStatusMessage == "") then
-- We're downloading...

-- Shorten the TransferRate to 2 decimal places
local TransferRateFormatted = string.format("%.2f", TransferRate);

if(FileSize > 0) then

local StatusText = TrueUpdate.GetLocalizedString("MSG_ESTIMATED_TIME_ LEFT")..": "..EstimatedTimeRemaining.." - "..TrueUpdate.GetLocalizedString("MSG_TRANSFER_RAT E")..": "..TransferRateFormatted.." "..TrueUpdate.GetLocalizedString("MSG_KB_PER_SEC") ;
DlgStaticText.SetProperties(CTRL_STATICTEXT_LABEL_ 02, {Text=StatusText});
else

local SecondsElapsed = os.time() - screen_globals.TimeStarted;

local TimeElapsed = g_GetFormattedTime(SecondsElapsed);

local StatusText = TrueUpdate.GetLocalizedString("MSG_ELAPSED_TIME"). .": "..TimeElapsed.." - "..TrueUpdate.GetLocalizedString("MSG_TRANSFER_RAT E")..": "..TransferRateFormatted.." "..TrueUpdate.GetLocalizedString("MSG_KB_PER_SEC") ;
DlgStaticText.SetProperties(CTRL_STATICTEXT_LABEL_ 02, {Text=StatusText});
end

else
-- We're waiting for the server...

-- Show the current status message
DlgStaticText.SetProperties(CTRL_STATICTEXT_LABEL_ 02, {Text=ServerStatusMessage});
end

-- Tell the GetServerFile action to continue
return true;
end

------------------------------
-- Download the server files
------------------------------

-- Get the list of TrueUpdate Server locations
local tableTrueUpdateServers = TrueUpdate.GetUpdateServerList();

if(tableTrueUpdateServers) then

screen_globals.TimeStarted = os.time();

for index, ServerName in tableTrueUpdateServers do

screen_globals.CurrentServerIndex = index;

screen_globals.GotServerFiles = TrueUpdate.GetServerFile(ServerName, true, GetServerFileCallback);

-- Break out of this loop if we succeeded
if(screen_globals.GotServerFiles) then
break;
end
end
end
