Anything can be an embedded resource. Add the XML document to your project, right-click and select Properties. In the PropertyGrid, change the Build Action to Embedded Resource.

Use Assembly.GetManifestResourceStream to pull it out. The root namespace of the project (in the project settings) plus any folders in which an emedded resource is located comprise it's "namespace" (as well as the default namespace for source files, though you can override this after the file is created).

When you're drawing your column, check the DataGrid.Right property. If it's less than your column's right side, then subtract the difference; if not, draw the whole column (cell, actually) as highlighted (or whatever you're doing).

Hi.
I have a side bar with a menu in an iframe, this sidebar is is very long (heigh). When I click on a button at the bottom of the menu, it reloads and gos up to the top. I want the srollbar to stay at the bottom when I click on this button.

Can I somehow use the (not) IsPostBack on the button? How can I do this?

Thanks!

For starters, this belongs in the ASP.NET forum. If you don't want the button to post back, however, then don't make it a server control. A simple button element with an onclick handler will do. If you need more information, ask in the appropriate forum.

You need some javascript function because each postback is a submit in your page. I was with this problem but with linkbutton and I solved it without js just by setting href="" and not href="#" like I did... but it was a linkbutton! Good luck!

just add a regular HTML button input type to the html, and don't rely on the designer to much...:

<br />
<input type="button" onclick="CallSomeJavaScriptFunctionHere()" /><br />

JS code (just googled for it...

<br />
function scrollToBottom() { <br />
         document.body.scrollTop = document.body.offsetHeight; <br />
      } <br />
<br />
      function checkIfScrollToBottomIsNeeded() { <br />
         scrollToBottomIsNeeded = ( document.body.scrollTop >= ( document.body.offsetHeight - ( window.innerHeight * 1.2 ) ) ); <br />
      } <br />
<br />
      function scrollToBottomIfNeeded() { <br />
         if( scrollToBottomIsNeeded ) <br />
            document.body.scrollTop = document.body.offsetHeight; <br />
      } <br />

foo myObject = new foo();

Type t = myObject.GetType();

// how do I create a new object of type t ??

Take a look at the Activator.CreateInstance method.

The way i tend to do it is to get the constructor (usually the parameterless one) and call invoke on it using reflection..

<br />
Type t = ....<br />
<br />
ConstructorInfo constructor = t.GetConstructor(System.Type.EmptyTypes);<br />
<br />
object newObject = constructor.Invoke(null);<br />

Well, I just googled for it and discovered I need not have gone so far. The top item in Google's search was right back here at Code Project.

Although this example is in in C++, I don't think it would take much to translate it to C#

Well, you could also try going to the References folder of your project and Add Reference to the COM library "Messenger API Type Library". You'll have to declare an object of type MessengerAPI.Messenger or something close to that. I don't exactly know what it would be because I don't use MSN or have Messenger installed.

? Access controls belonging to another application

Hello!
I wonder if there is a way to access the properties of the controls of another application's forms at runtime...
For example, i want my application to monitor wether a checkbox on another application's form has or has not been checked.
A non-.NET solution would also be useful.
If anyone has ideas, please reply!

You're likely looking at using Win32 API P/Invoked calls to FindWindow and GetWindowLong. How comfortable are you with the old APIs?

There is no easy way of doing this and no support it in the .NET BCL. Like Jeremy said, "How comfortable are you with the Win32 API?" You'll need to have an in depth knowledge of how windows and controls work and how to pass messages to these windows to get information back from them.

I have made some 'research' based on Jeremy's suggestions and, indeed, there is no easy way to do that since I'm not very familiar with the Win32 API. I guess i'll wait for future managed implementations..
Thanks anyway!

Not likely going to happen. What you want to do is difficult because most of the time you have to write custom code to even find the window your looking for, then not all windows are going to expose their properties the same way. Some you can get through send message back and forth, others you have to cast a point to the Win32 Class (not the .NET Framework class!) to get at the properties.
