C#: Display a pdf in WindowForm

Question

Hello!
I am reading the documentation and this forum for a few days, but my problem isn't really solved.
I want to display a pdf document in a WindowForm in C#.
CAcroPDDoc pdDoc = new AcroPDDocClass();
pdDoc.Open("C:\\test.pdf");
CAcroPDPage pdPage;
pdPage = (CAcroPDPage)pdDoc.AcquirePage(0);
AcroRect rect = new AcroRect();
rect.Left = 0;
rect.Top = 0;
rect.right = 1000;
rect.bottom = 1000;
pdPage.DrawEx(0, 0, rect, 0, 0, 100);
With this, I am able to display or render the first page of a document. It's just rendered, nothing more. I read, that I can implement a piece of the acrobat reader, so that I don't have to implement everything on my own.
I think this is something like this:
CAcroAVDoc avDoc = new AcroAVDocClass();
avDoc.Open("C:\\test.pdf", "Test");
But I don't know how to display this pdf in my application. What I want to do is to open a new window and display a pdf + some extra functions, that i want to code on my own. I thought about the BrowserComponent of VisualStudio, but there I am only having control of which page to display, but no chance to get the actual displayed page, right?
I want to get the actual page and set the page when the document is opening.
It would be very great if you could help me. I really don't know a good solution for this and my trials all didn't work.
Thank you very much for your reply,
Manuel

Thanks for your answers!
My problem is, what malkyt explains. I want to add the Reader to my Toolbox Items. But in my COM Components tab, there are only 2 Items, but no Adobe PDF Reader.
Now I copied the AxInterop.AcroPDFLib.dll and the Interop.AcroPDFLib.dll from an example in the SDK. I found some code to display a pdf (http://www.sciencecode.com/text.htm#30):
try
System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(PdfForm));
AxAcroPDFLib.AxAcroPDF axAcroPdf = new AxAcroPDFLib.AxAcroPDF();
((System.ComponentModel.ISupportInitialize)(axAcroPdf)).BeginInit();
axAcroPdf.Location = new Point(50, 50);
axAcroPdf.Size = new Size(500, 500);
axAcroPdf.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("axAcroPdf.OcxState")));
this.Controls.Add(axAcroPdf);
((System.ComponentModel.ISupportInitialize)(axAcroPdf)).EndInit();
axAcroPdf.LoadFile("C:\\test.pdf");
axAcroPdf.Show();
catch (Exception ex)
MessageBox.Show(ex.Message);
But if I do this, I get something like this:
"Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))"
What am I doing wrong? How can I get this COM-Component or can I just use these 2 libs from the examples?
Many many thanks!!!
EDIT: Okay, on my Laptop (WinXP) this works. Vista64Bit doesn't show these components. Now the pdf is displayed and I am very happy. But how am I able to hide or deactivate the "save"-button? I don't want, that the user can save this document.
