Load settings to a visual studio GUI app, to be read while loading gui

Question

0.00/5 (No votes)

See more:

I have a visual studio C# GUI application, where I want to initalize some settings, before loading the gui.
At the moment I have a gui with a button, where I "load" the settings. But it does not work, since some of the settings should be done before the gui loads:

public static void initializeSettings(bool bShow) {
    //First, the log: 
    log__ = Logger.Current;

    //And settings, read from  config file (placed in bin folder):
    settings__ =  MySettings.Current; 
    
    //Set globalmember preprocessing parameters:
    runNumber_ = settings__.getInt("run.Number", 3); 
 
    iDelayMillisecs = settings__.getInt("DelayMilliSecs", 10);
    myString = settings__.getString("myString", "defaultString");
    myBool = settings__.getBool("myBool", true);
    
    //Set folder:
    strLogFolder_ = settings__.getS("FolderInput", "C:/logfiles");
 }

So I guess there must be a place to place code to load before the Main window opens?

What I have tried:

<pre>Settings are defined in a App.config file like this example:


<configuration>
  <startup>
    <supportedruntime version="v4.0" sku=".NETFramework,Version=v4.8">
  
  <appsettings>
	  <add key="Language" value="CSharp">
	  <add key="Copyright" value="Copyright © blabla">
	  <add key="SmtpClientName" value="blablabla">
	  <add key="PortNo" value="25">
	  <add key="userName" value="blabla">
	  <add key="password" value="blabla">
	  <add key="LastNumOfcharsFromLogfileToErrorMail" value="1500">  
	  etc....
  
At the current point the program is working fine, but with no gui.
Anyone for a quick help? I'm sure it's possible, but I cant find any "initialization" or something like in visual basic

Yes, there is. Really settings are outside of presentation, so I'd create a settings class and keep them in there.

internal static class Program
{
    [STAThread]
    static void Main()
    {
        ApplicationConfiguration.Initialize();
        Application.Run(new Form1());
    }
}

I'd do it before the Application.Run(). If in the Form, how about the Form_Load event rather than a button? This gets called after the form is created but before it is displayed.

BTW - you've got some strange variable naming convention going on there..
