On top of what Kumar said, ScrollToCaret() only works if the RichTextBox has the focus. You might want to insert a call to .Focus() before you call ScrollToCaret().

Hi,
I am trying to grab a video clip from a movie in C# using DirectShow. I am using DirectShowNet project which I got from codeproject.com.It is working well when i am using devices like web cam etc .
I am getting problem in playing a movie which is stored on hard disk and capturing video clip from it.
An Exception is raised when SetupGraph() function is invoked from
RenderStream() function "Invalid Parameter".
I had used FilterCategory.LegacyAmFilterCategory as first argument to
DsDev.GetDevicesOfCat() function.And from the list of devices displayed by DeviceSelector class I am selecting 'File Source(async)'

hi all,
I need to give user name and password to windows 2000 Professional Logon Dialog using C# Application..
after that I need to access the computer without giving user name and password..
How can I do that?
|
|

|

I believe there's a dll that controls that on W2000, which you can replace with your own. As far as doing it to ANY W2000 install, I don't see how you could, the system would not be very secure if it allowed you to run code on a machine that has not been logged into. You may even have trouble because you're looking at C#, and the .NET framework may have trouble starting before anyone is logged in.
How do you want to access this computer ? Control it ? I really think you're talking about a C++ program here. You'd just end up importing so much API stuff, you're better off starting there.

I am fit with C++..
Can u tell me how to do that using C++?
I want to send values to User name and Password in "Log on to Windows" Dialog using C# or C++.
I am doing this because I can avoid entering username, password again and again..Then I can log on to machine automatically
OR Is there a another way to fullfill this?(using Windows Properties)
However my computer in a Domain..NOT in a WorkGroup.
If I am in a WorkGroup,I can easily Disable Appearing "Log on Dialog Box".

Can't be done.
What you should be looking into is setting up Auto Logon. See here[^]. No code required...

I am using the following code to create a graphics object (image) which i then write text to and display on the screen. When I try to resize the object's width i get an error saying that it is read only? What does this mean and how can I resize it?
m_objDrawingSurface = new Bitmap(this.ClientRectangle.Width,
this.ClientRectangle.Height, System.Drawing.Imaging.PixelFormat.Format24bppRgb);
To resize it I am trying to use:
m_objDrawingSurface.Width = this.ClientRectangle.Width;
Im trying to resize the image to match the window size when it changes.
Could someone please help to correctly change the size??

The property is indeed read only - a Bitmap does not allow you to change that sort of thing. You need to create a new Bitmap, use Graphics.FromImage to get a graphics object, and then draw your bitmap into the graphics object at the dimensions you want to convert it to. Bitmap.Clone also has a method that takes a size, but the size needs to be smaller, and it makes a copy of part of the image, it does not resize.

Hey,
I want to write a peice of code which can be useful to shut down my computer from C# programmer. I want to call executable responsible for shutting down computer is it possible?
|
|
|
|

There are API calls that do this, which you can import into C# and call. The .NET framework has nothing to do this for you. I googled for more info ( my code to do this is at home ), and this is the first link I found:

You can use the following which is actually a shell command:
System.Diagnostic.Process.Start("shutdown","/s")
For a different tactic, take a look here[^].

Yes, it's possible! I had the same problem a month ago
Go to http://www.mentalis.org/soft/class.qpx?id=7 download WindowsControler. To shutdown your computer you need to add WindowsController.cs to your project, add line "using Org.Mentalis.Utilities;" ....... and
WindowsController.ExitWindows(RestartOptions.ShutDown, true);

can any body tell me "in very simple words" that what are the indexers. i am a just a beginner to c#. so please use very easy language.
i am athar
|
|

|

Well, I guess one could say that Indexers are just a way of allowing your Class to be used and accessed just like an array. No wonder why they are also called "virtual arrays". For a rather self-explanatory tutorial take a look here[^].
Hope this helps you get the overall picture.

Polis

You can imagine indexers to be like overloading [] operator in C++. They essentially allow you to treate your object like an array.

Hi,
I'd like to create user controls like I'm used to in windows forms
is it possible or should I use something else?
I'd like to re-use my basic IU with menu buttons and load misc. lists or status usercontrols into a placeholder..
thanks,
H

So what you are actually saying is that you need a good tutorial what will help you with your first user control? If this is the case, take a look here[^].
Hope this helps.

Polis

Well, yes.. it does.. a little..
Is it possible to make a user control, visually, like the ones in Windows Forms ?
For my PocketPC app..

|

|

Ooops, I am sorry. I didn't notice it was for a pocket pc application. Take a look at the following links then. They are specific to the .NET Compact Framework:

i want to know how to go to a different 'room'.
Eg. In an rpg, you walk through a door of a building and you go to a different 'room' (the inside of the building)
or in a game like sonic, you move to the next 'room' (the next level).
Any ideas on how to do this.
(i do not need any help on collision checking or anything, just how to redraw the entire room to the new one)
Thanks i advance, i know i'll get some help here 
|

The way that these things generally work is that you have an array of structures that represent your 'rooms', and each room 'knows' what other room in the array a door points to. Then you just change the room you're pointing at in the array, and call a generic function that draws it, and so to the code to interact with it uses this structure to know what's there.
That's assuming you go to the edge of the screen and walk into another room. If you are always scrolling, then you need one big map.
The idea really is to write generic code that knows how to interact with *everything*, code that knows how to draw *any* room, then use a data structure to change what room you're interacting with. This is also why it's so easy to provide a map editor with most games. It just edits that structure.

You can simply make a class or method that called Room() ,
This method or class ,whatever,will draw the default room that will be used in all the room ,and then just make a method named Room1(),Room2(),Room3(),etc... , and these method will contain the additionla data for it's room ,
Maybe Room1() will contain one person ,but two contains two animals ,so the default room will help you in this.
