Re: Assemblies with C# Eric Gunnerson (msft)21-May-02 10:38 Eric Gunnerson (msft) 21-May-02 10:38  It's not quite clear what you're asking. Assemblies are the unit of deployment/packaging in C#. If you write something like: csc /target:library /out:lib.dll a.cs b.cs c.cs d.cs q.cs all the files will get compiled and packaged into lib.dll. To use the assembly from the command line, you use /r to reference. To use it from VS, you add it as a reference to the project. If that doesn't help, please ask again. Re: Assemblies with C# Rickard Andersson2021-May-02 20:45 Rickard Andersson20 21-May-02 20:45  With other word you could say: An assembly is an EXE or DLL, something that you can execute.... right?

Often, but not always. An assembly can be made up of multiple files that are all thought of as part of the 'assembly'. So, for instance: A single-file assembly: MyAssembly.dll A multi-file assembly: MyAssembly.dll MyPic.gif OtherPic.gif CompiledModule.netmodule The single-file assembly is just that - a completely self contained assembly. The multi-file assembly is an assembly that is made up of multiple files. The MyAssembly.dll contains an Assembly Manifest, which references the external files MyPic.gif,OtherPic.gif, and CompiledModule.netmodule as being part of this assembly. VS.NET won't really let you explicitly build multi-file assemblies, but they can be easily built from the command-line compiler. Anyway, the point of the matter is that an 'Assembly' is a logical, versioned unit of code and data deployment. Assemblies aren't always contained in one file. -- Russell Morris "WOW!

Help for a beginner Giladi19-May-02 23:33 Giladi 19-May-02 23:33  Hello I'm a newcommer here, and I would like to state that this is a great helpfull site. Thanks for all the contributers!! I am trying to open a form from within an existing running form (both under the same namespace), E.g. an "About" popup. I tried "Application.Run(new AboutWindow());" Compilation ends successfully but when i press the designated button, the application crashes. Ideas will be most welcome, thanks all Gilad Re: Help for a beginner Nish Nishant19-May-02 23:41 Nish Nishant 19-May-02 23:41  Use Form.ShowDialog to show the About form.

Thanks a lot!! Gilad Form Inheritance SimmoTech19-May-02 22:07 SimmoTech 19-May-02 22:07  After spending a long time on a current VB project with 30 similar but different forms, I was looking at using c# and inherited forms to see how much easier it could be. I have a base form with a tab control on it complete with two tabs that will be common to all inherited forms. e.g "General" and "Other Info" What I want to do is add additional tabs between these inherited tabs on the inherited forms. This works ok in Visual Studio (ie. I can move my new tab to between the existing tabs) but when the project is executed, the new tab is put back at the end of the list again. Is this a bug in VS or more, likely, a design limitation? What is the best way to achieve this. I want to keep the GUI mode modification of the tab layout but it seems to be wasteful to have VS create the collection in InitializeComponents() only for me to immediately do the same thing again.

Moving PictureBox Around Nick Parker19-May-02 13:52 Nick Parker 19-May-02 13:52  I have a picture in a picturebox and I would like to move it around within the bounds of the form. I like the idea of it changing directions when it hits the outer edge of the form. What is the best way to do this? I have this, but it really isn't doing a whole lot. Thanks in advance. void MovePic() { for(int i = 0; i < this.Width; i++) { this.picbox.Top += 1; this.picbox.Left += 1; } } Nick Parker Actually, real programmers don't need the enter key- they just type in 00001101." Re: Moving PictureBox Around SHaroz20-May-02 7:58 SHaroz 20-May-02 7:58  You might want to creat VMove and HMove variables. So it would look like this: void MovePic() { for(int i = 0; i < this.Width; i++) { this.picbox.Top += VMove; this.picbox.Left += HMove; } } Then when it hits an edge, just negate one of the variables. help! how can I rewrite struct with union in C#? Li-kai Liu (Angus)18-May-02 18:20 Li-kai Liu (Angus) 18-May-02 18:20  Hi, In C or C++,some structures are defined with union. How can we rewrite these structure in C# so that we can use them as parameters and pass them into API functions? And, What's the correspondent type in C# to PVOID type in C? Thanks in advance!

How can we rewrite these structure in C# so that we can use them as parameters and pass them into API functions? e.g. union U { int x; int y; } can be written in C# as [StructLayout(LayoutKind.Explicit)] class U { [FieldOffset(0)] int x; [FieldOffset(0)] int y; } ykliu wrote: And, What's the correspondent type in C# to PVOID type in C? There are two equivalents of PVOID in C# 1. void* this is when you are using C# pointers. Something which you should never do. 2. IntPtr this is used to encapsultae unmanaged pointers. Use this in conjunction with Marshal.StructureToPtr, Marshal.AllocCoTaskMem etc. functions. Look up all the functions in Marshal class it would be very helpful.

I will keep reading some document before asking another question. Angus Liu about Rama's screensaver? zhoujun18-May-02 17:15 zhoujun 18-May-02 17:15  i downloaded Rama's screensaver. i want to ask a few questions: 1,when i test or run the screensaver,what did it do except display moving pictures?in James' screensaver when i press the "h" key,it will display help information! 2,Rama said "RBWRP.dll - This is a Managed C++ application that links with Ravi Bhavnani's WebResourceProvider libary to obtain Code Project Top 10 posters." you obtain topposters through "webresourceprovider.lib" or "cp's webservices"? and in RBWRP.dll,how to link with "webresourceprovider.lib"?(maybe stupid question,but i am a beginner,so forgive me ) thanks in advance!

So it's James screensaver now ? Are you reading this James ? Seriously, our screensaver is a bit non-standard in that it has a number of keys. Most screensavers do not AFAIK. Rama AFAIK does not use the webservice as he had written his own ultra cool web service for harvesting information. That's why he has the top 10 posters, although the web service does not offer that.
