InfoPath Dev

I think the second pic is not the correct one what I intended to show, this pic would be more relevant  

 Lemme explain it this way. Normally when we open a browser enabled infopath form, saved in the document library it opens like this. But what I want is to show it as a part of portal like, something like the below shown screen when clicked on the link of the form saved in the document library.  

When we open the form in the first way as you mentioned, the form opens in the browser and the form occupies the whole browser space. But what I want is that form should fit in the portal that is with all the top tabs, left menus and all that. Something like, the master page should remain the same and the form should be the content page. Am i ...

 Yes, Normally when we open the form it opens in complete browser. But I want it to be opened in the portal.

 I have a document library that saves infopath forms. When a user clicks the link of the form in the document library, the form should be open in the portal. Is this possible ? Can anyone tell me how to do this or suggest me any article for this?

 Hi Clayton, Thanks for the reply. I will try this and let you know the result.

I have an infopath form submitted to a document library and a worklfow is associated to it. Can the whole form be set to read only once the form is submitted and saved in the document library, So that the user can not make any changes to the form he submitted to the document library once the approver approves the form.

 Hi, Is there any way that we can check-in and check-out a form through code so that we need not check-in or check-out the form from the library each time we open it.

Thanks for the reply Patrick.Can you tell me how or can you show me some articles that explains how we can deploy aspx pages into sharepoint portal, how to save then in library and how to assign a workflow to it?

Hi,  Can an asp.net web application replace Infopath form in MOSS? Say if we do not have enterprise license and we want some forms to be filled by users and assign a workflow to it. How can this be done if infopath form services is not available?
