screen scraping - C#: Need to render a form/control on an "imaginary" desktop -


OK, what I'm trying to do here. First of all, I will explain the end result, as a result I am trying to get it, there are other ideas about doing this.

I am creating a screen capture utility which only takes the screen shot of a window ... my window (which I have total programmatic control). However, this window can be very large compared to the computer on which the utility will run. The height, in particular, can reach up to several thousand pixels on a computer with 1024x768 resolution.

So I am trying to capture the entire window, though it is bigger than the screen. I am trying to achieve the end result of this.

A hypothetical solution is to render the form / control on any type of graphics or screen object, and instead of turning off the object's screen, instead of taking the screen shot of the physical desktop.

Basically I need to draw control over an imaginary screen which is present only in code and memory and I do not even know what to look for, so also consider whether Google (true search engine) It would be helpful to put

Any thoughts? thank you in advanced!

EDIT: I am using WinForms.

What technology you did not use to use your C # application, I'm assuming WPF

If your implementation uses WPF, then you should only assign it to a drawing image with correct dimensions - or even an image in memory Use WPF printing capability to print window contents. That you may be able to optimize (if you are using WPF).

With a WinForms application, this is a bit complicated because WinForm controls do not always go well under higher resolution, and alignment problems. This refers to a UserControl printing, but you should be able to optimize the implementation for your purposes.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
