[Help] ErrorLog C#

[snigelmannen]

Hey another thing which i need help with.

My current tool gets this when it fails to read the process and read from the process.




so instead of the window, how can i print the messages to a text box?

[ReidE96]

try-catch (C#)

[snigelmannen]

Read about try and catch though didnt find that page, thanks

[ReidE96]

Glad to help out

Well wall o crap inc

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Magic;

namespace SnigelStatus
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            
            BlackMagic WoW = new BlackMagic();
            WoW.OpenProcessAndThread(SProcess.GetProcessFromProcessName("WoW.exe"));
            string PlayerName = WoW.ReadASCIIString(0x00C923F8, 12);
            uint PlayerBase = WoW.ReadUInt(WoW.ReadUInt(WoW.ReadUInt(0x00CF7C00) + 0x34) + 0x24);           
            uint CurHealth = WoW.ReadUInt(WoW.ReadUInt(PlayerBase + 0x8) + (0x17 * 4));
            uint MaxHealth = WoW.ReadUInt(WoW.ReadUInt(PlayerBase + 0x8) + (0x1F * 4));
            int HPPer = (int)(((double)CurHealth / (double)MaxHealth) * 100);
            progressBar1.Value = HPPer;
                   
        }
    }
}

How would you guys make that code execute only if there was a process, and if there wasnt it would write to my error log?

[ReidE96]

try
{
    WoW.OpenProcessAndThread(SProcess.GetProcessFromProcessName("WoW.exe"));
    string PlayerName = WoW.ReadASCIIString(0x00C923F8, 12);
    uint PlayerBase = WoW.ReadUInt(WoW.ReadUInt(WoW.ReadUInt(0x00CF7C00) + 0x34) + 0x24);           
    uint CurHealth = WoW.ReadUInt(WoW.ReadUInt(PlayerBase + 0x8) + (0x17 * 4));
    uint MaxHealth = WoW.ReadUInt(WoW.ReadUInt(PlayerBase + 0x8) + (0x1F * 4));
}

catch (Exception e)
{
    Console.WriteLine("{0} Exception caught.", e);
}

[snigelmannen]

Thanks for the help will try it.

[snigelmannen]

Hmm another question, ehm console writeline can that be change to the errorlog i have? like Error.Writeline?

[ReidE96]

Yep, you can do whatever you like with the error. That's just one option. The variable e is the exception.

[snigelmannen]

Well i am getting an error when writing to that box but that's because its a richtextbox or w/e its called, cant use writeline with it, its something else that i gotta use.

been looking it up but it still doesn't give any good answers.

and thanks for the help with try - catch it doesn't crash anymore and just stays open when it doesn't find the process, though i had to move the whole code within the try catch. else it would fail, as stated not a coder i don't know how this all works.

[ReidE96]

richTextBox.AppendText() is the method you're after.

Try-Catch works by trying to execute the code in the Try block, then catching any error that happened whilst doing so.

[snigelmannen]

Well its working quite as i wanted now, just gotta learn how to truncate it some.




Now i tried to add a error sound, it went well as it plays the sound sadly it spams it got a better solution then the below?

            catch (Exception SProcess)
            {
                
                ErrorText.Text = "Error" + SProcess;
                SoundPlayer simpleSound = new            SoundPlayer("http://snigelmannen.dnsdojo.org/SnigelStatus/moo3.wav");
                simpleSound.Play(Stop);
            }

[ReidE96]

What do you mean by "spams"? I'd use a soundplayer myself if I wanted to play a sound, it shouldn't repeat unless you tell it to.

[snigelmannen]

Well if you can be bothered ill just put the link to the version with the error sound.
