GetFields returns only fields (member variables) in that type. Type.GetMethods[^] returns functions defined in that Type.

Thanks Senthil,

Looks like GetMembers return both methods and fields, and GetMethods/GetFields returns just method/field? So, GetMembers is more powerful. Smile | :)

Call GetMembers then.

Every single type defined derives from Type as a RuntimeType.

For any user defined class, does the class implicitly derives from Type?

The field abc is defined as static, but in your GetFields() call you ask it to return only instance fields.

Thanks Vega02,

I think the root cause is, I do not know GetFields will not return methods before. Smile | :)

You can use the ServiceInstaller class. It's part of the BCL.

Well there are certain ways to add a service to your windows registered services.
1) You can use the InstallUtil tool that comes with the .Net Framework;Go to the Visual Studio Command prompt and there type InstallUtil Path-to-Assembly-to-be-installed-as-service
This is a manual procedure.

2) Create a new setup project using the Visual Studio Setup Wizard and then under the "File System Editor" add the output (the assembly that you want to install as service", after this go to "Custom Actions Editor", you will see four folders there, 1- Install, 2- Commit, 3- Rollback and 4- Uninstall, right click on Install and click on "Add Custom Action" from the resulting menu, under the result dialog, locate the application folder and locate the assembly of the service that you just added in Application Folder, double click on this assembly.
Now when you run the setup project, the service will be added to your windows services if everything goes well.

For both the procedures, you would need to go to windows services console and start the service manually.

on the buton of form1 call this and form is opening succesfully but when i closed the form2 then its back to form 1 , becouse form 1 is already opend then my question is that which event is fire when i got back to form1 , i checked Activated event is not working may b cumming from other project , may what is differnce b/w show and showdailogue() , when i call like f.showdailogue() ; then its just open and closed automatically .

Further Detail :
i have a image on form1 i move this image to form2 and edit that image and then save and when i return back to form1 then its should automatically update but its not updated , when i found the event then on that event in form1 i just reload the image to given path .

You should have to code on FormClosing event of form2 to notify your form1 that form2 is closed and than... on recieving notification u can reload your image.

project1.form1 g = new project1.form1();
g.picturebox.Image = null;
g.picturebox.Image = Image.FromFile(@"C:\Temp\Temp2.jpg");
g.picturebox.Refresh();

but after this coded still no differnce in form1 picture box , but when i came to form1 then i made here update button when i pressed it then its update on update button i coded
g.picturebox.Image = Image.FromFile(@"C:\Temp\Temp2.jpg");
g.picturebox.Refresh();

Yes, there is, but you can't see it. You have created a new instance of form1, in which you are changing the picture box.

If you want to change the picture box in the existing instance of form1, you need a reference to it in form2. Add a private variable of the type form1 to form2, and a parameter in the constructor of form2 of the type form1. Send a reference to form1 (Me) when you create the form2 instance, and in the constructor you store that in the private variable.

Despite everything, the person most likely to be fooling you next is yourself.

The reason it's not updating bcz u r making a new instance.. on formclosing event but u need the already open instance.

you need to see your code again... u r creating a new instance of form1 instead of working with the instance in which u r expecting to see the change.
