AFAIK, the config file only stores strings. You could easily convert the color to a numeric value and store its string representation (name or RGB values) and do the reverse on the way out.

Passing command line arguments to the main method

How to convert a Color object to and from a string, for storing somewhere, has already been answered in your previous post regarding saving this value to the registry.

Please check there first. Once you understand this, the question of how to write it/read it to some form of configuration file is easy, and should be explained in the article linked above.

This just baffles me!

I know it is something simple and right under my nose but cant figure it out

static void Main(string[] args)

{
MessageBox.Show(args[0]);
}

How do i pass in arguments prior to running this program.

1) Create a link, and add them to the textbox that points to your program

C:\Programs\MyFile.exe -parameter1 -parameter2

2) Open the command prompt and do the same:

> MyFile.exe -parameter1 ...

3) In Visual Studio:

Menu: "Project -> [Program] properties..."

Then on the left: "Debug" and in the middle: "Command line arguments"

There are plenty of other possibilities, but these are the most common ones.

Alternatively, create a shortcut to your application and edit the shortcut by Right-clicking and selecting properties.

On the 'Shortcut' tab, just add the arguments you want in the target box so:

Target: "C:\program files\my app\my app.exe"

would become:

Target: "C:\program files\my app\my app.exe" myArgument1 myArgument2

This way you can setup different shortcuts that each pass different arguments.

Hope this helps.

TraceSwitch doesn't get settings from App.config

Optimus Chaos12-Feb-06 4:31

Hi folks,

I have a problem concerning a TraceSwitch I'm using in one of my recent projects:

I have a library assembly which is being referenced from a Windows service. Within this library I have several classes, dealing with file searching and parsing. the classes are designed for general use, so I don't write errors from the library in the Event Log. To enable tracing in the library I created a static class with two static members, the switch and the TraceListener (will write to a text file). For the library I created an App.config file withe the following XML code:

<br />
<system.diagnostics><br />
    <switches><br />
        <add name="ParsingLibTraceSwitch" value="3" /><br />
    </switches><br />
</system.diagnostics><br />

The code for the Tracing class is like this:

<br />
namespace ParsingLib<br />
{<br />
    public static class Tracing<br />
    {<br />
        private static TraceSwitch tracer = new TraceSwitch ( "ParsingLibTraceSwitch",<br />
            "Enables tracing for the ParsingLib assembly" );<br />
<br />
        private static TextWriterTraceListener traceListener = <br />
            new TextWriterTraceListener ( "ParsingLib_Trace.txt" );<br />
<br />
        public static TraceSwitch Switch<br />
        {<br />
            get { return tracer; }<br />
        }<br />
<br />
        public static TraceListener Listener<br />
        {<br />
            get { return traceListener; }<br />
        }<br />
    }<br />
}<br />

However, if I run and debug the service, the TraceLevel of the Switch is always TraceLevel.Off.

Does anyone of you have an idea what's wrong with the code? I'm using VS 2005.

Thank you in advance.

How To Load App Setting From Registry ?

Re: How To Load App Setting From Registry ?

12-Feb-06 1:55

hi i want to save app setting in registry (for example dataGrid1.AlternatingBackColor)
and this is way that i used for save value to registry :

RegistryKey regkey = Registry.CurrentUser.CreateSubKey(@"SST\Full_SaveSetting\Setting");
regkey.SetValue("Datagrid_AlternatingBackColor",dataGrid1.AlternatingBackColor);

and when i load dataGrid1.AlternatingBackColor from registry as following :

RegistryKey regkey = Registry.CurrentUser.CreateSubKey(@"SST\Full_SaveSetting\Setting");
dataGrid1.AlternatingBackColor=(System.Drawing.Color)regkey.GetValue("Datagrid_AlternatingBackColor");

An unhandled exception of type 'System.InvalidCastException' occurred in it :
Additional information: Specified cast is not valid.

how to cast regkey value to color to solve my problem ????????

I haven't tested your code but have you tried reading/writting the ARGB value to/from the registy?

It would be something like:

 dataGrid1.AlternatingBackColor.ToArgb(); //when writting to registry<br />
<br />
dataGrid1.AlternatingBackColor = System.Drawing.Color.FromArgb( argbValueGoesHere ); //when reading from registry<br />

hi and thanks ::
but what is the argbValueGoesHere ?
and System.Drawing.Color.FromArgb() get an integer value and when i pass

regkey.GetValue("Datagrid_AlternatingBackColor")

to it don't accept it and when i cast it to int as following :

(int)regkey.GetValue("Datagrid_AlternatingBackColor")
it say me :

Specified cast is not valid.
how to do that ????

OK, the pointer should have been enough, but this is a sample from your code example:

To write color to the registry:

RegistryKey regkey = Registry.CurrentUser.CreateSubKey(@"SST\Full_SaveSetting\Setting");<br />
			regkey.SetValue("Datagrid_AlternatingBackColor", dataGrid1.AlternatingBackColor.ToArgb() );

To read color from the registry:

RegistryKey regkey = Registry.CurrentUser.CreateSubKey(@"SST\Full_SaveSetting\Setting");<br />
			dataGrid1.AlternatingBackColor = System.Drawing.Color.FromArgb( (int)regkey.GetValue("Datagrid_AlternatingBackColor") );

Personally, I think that using the registry to store this kind of information is a bad idea, just think, if the user wants to load the app on another machine, these preferences would have to be re-configured on the new machine. There are other ways EG using the app.config file etc.

what's the difference between using the pagesettings property in the PrintDocument.PrintPage event vs the PrintDocument.QueryPageSettings

i know QueryPageSettings is thrown first, but like if you want to change the margins of your new printed page, u can use both events, or not?

Hello ,
Thanks a loot for the response. but what if i dont want to make parent form MDI container. Is not it possible to call method in parent form without MDI container declaration ?

Thanks

Josh Smith12-Feb-06 12:17

Make sure that when the parent form creates the child form, it sets the child form's Owner property to 'this' (this parent form instance).

// MainForm creates child form and sets the Owner.
ChildForm childForm = new ChildForm();
childForm.Owner = this;
childForm.Show();

Then in the child form you simply cast the Owner property to a MainForm and call your method.

// ChildForm casts Owner to MainForm and calls method.
MainForm parent = this.Owner as MainForm;
parent.SomeMethod();

The problem with your initial code sample is that it creates a new instance of MainForm, which is not the same instance as the actual parent form.
