fileRead client

[JAVAAA]

Hello, I am asking about how to read a file in the server and get the data from it into client? I tried a lot of times but nothing happens at all.

Server : 

function getUpdates()
	local updates
	local file = "UpdatesLog.txt"
	local size = fileGetSize(file)  
	local openFile = fileOpen(file) 	
	if openFile then
		while not fileIsEOF(openFile) do
			updates = fileRead(openFile, size)
		end
		fileClose(openFile)
	end
	triggerClientEvent(client, "getUpdates", client, updates)
end

Client : 

	local key = "F1"
    updatesPanel = guiCreateWindow(195, 64, 986, 579, "Updates Changelog", false)
    guiWindowSetSizable(updatesPanel, false)

    updatesMemo = guiCreateMemo(10, 26, 966, 539, "", false, updatesPanel)    

	guiSetVisible(updatesPanel, false)
	
	guiSetInputMode("no_binds_when_editing")
		
function showAndCloseWindow(updates)
	if not guiGetVisible(updatesPanel) then
		guiSetVisible(updatesPanel, true)
		showCursor(true)
		guiSetText(updatesMemo, updates)
	else
		guiSetVisible(updatesPanel, false)
		showCursor(false)
		end
end
bindKey(key, "down", showAndCloseWindow)
addEvent("getUpdates", true)
addEventHandler("getUpdates", root, showAndCloseWindow)

fileRead is a Shared function... why don't you use it on client?

[Addlibs]

function getUpdates()
	local file = "UpdatesLog.txt"
	local openFile = fileOpen(file)
	if not openFile then outputChatBox("Error loading file") return false end
	local size = fileGetSize(openFile)
	local updates = fileRead(openFile, size)
	fileClose(openFile)
	triggerClientEvent(client, "getUpdates", client, updates)
end

Perhaps the file he wants to read is stored on the server?

Swapped lines 4 and 5

Yeah exactly.

I've made a quick correction (checking whether the file is open before reading its size) by swapping line 4 and 5 on the original reply, so just check the code again.

Now, the memo box's showing "F1" only while there is no text called "F1" in my .txt file.

function getUpdates()
	local file = "UpdatesLog.txt"
	local openFile = fileOpen(file)
	local size = fileGetSize(openFile)
	if not openFile then outputChatBox("Error loading file") return false end
	local updates = fileRead(openFile, size+500)
	fileClose(openFile)
	triggerClientEvent(client, "getUpdates", client, updates)
end

It works fine for me when I create logs file for exemple.

Perhaps you set as text the 'key' variable instead of 'updates'

Didn't work yet, here's my code now:

Server:

function sayUpdates()
	local localTime = getRealTime(_,true)
	local day = localTime.monthday
	local month = localTime.month + 1
	local year = localTime.year + 1900 
	outputChatBox("#F2D200["..year..":"..month..":"..day.."]NEW UPDATES! CHECK F1 TO SEE LATEST UPDATES!", getRootElement(), 255, 255, 255, true)
end
addEventHandler("onResourceStart", getResourceRootElement ( getThisResource() ), sayUpdates)

function getUpdates()
	local file = "UpdatesLog.txt"
	local openFile = fileOpen(file)
	local size = fileGetSize(openFile)
	if not openFile then outputChatBox("Error loading file") return false end
	local updates = fileRead(openFile, size+500)
	fileClose(openFile)
	triggerClientEvent(client, "getUpdates", client, updates)
end

Client :

GUIEditor = {
    label = {}
}
	--local key = "F1"
    updatesPanel = guiCreateWindow(195, 64, 986, 579, "Updates Changelog", false)
    guiWindowSetSizable(updatesPanel, false)

    updatesMemo = guiCreateMemo(10, 26, 966, 539, "", false, updatesPanel)    

	guiSetVisible(updatesPanel, false)
	
	guiSetInputMode("no_binds_when_editing")
		
function showAndCloseWindow(command, state)
	if not guiGetVisible(updatesPanel) then
		guiSetVisible(updatesPanel, true)
		showCursor(true)
		getUpdates()
	else
		guiSetVisible(updatesPanel, false)
		showCursor(false)
		end
end
bindKey("F1", "down", showAndCloseWindow)



function getUpdates(updates)
	guiSetText(updatesMemo, updates)
end
addEvent("getUpdates", true)
addEventHandler("getUpdates", root, getUpdates)

Gives me an error saying "Bad argument guiSetText, argument 2 expected string got nil"

You never call getUpdates()

Worked, thanks. I wonder how it didn't work with me while your code is completely similar to my previous code ^^
