Hi I am using this method to take screenshots from games in my application:

int screenWidth = Screen.GetBounds(new Point(0, 0)).Width;
int screenHeight = Screen.GetBounds(new Point(0, 0)).Height;
Bitmap bmpScreenShot = new Bitmap(screenWidth, screenHeight);
Graphics gfx = Graphics.FromImage((Image)bmpScreenShot);
gfx.CopyFromScreen(0, 0, 0, 0, new Size(screenWidth, screenHeight));
bmpScreenShot.Save("test.jpg", ImageFormat.Jpeg);

but in some games I can't get a proper screenshot. Sometimes some models are missing or only a black screen is captured.

Is there another method to capture screenshots from games? (Yes, they use DirectX)

Thanks.

Yes, you can ask DirectX for a copy of the backbuffer. I forgot how though but that would give you something to google for..

I wonder if there's a way to 'simulate' ALT+PrintScreen and then programatically get data from the clipboard and save it to a file? If there is... That oughta do it... I think

Dear Sir/madom

I have three tables

1. Categorys (ID, Name)
2. Definitions (ID, Name, CategoryID)
3. Versions( ID, Name, DefinitionID)

I have generated three objects using EDM
1 Cagegorys
Navigation (Definition)
2. Definitions
Navigation (Category, Version)
3. Versions
Navigation (Definition)

I want to get latest versions against each category

My Code is as follow It return all version against the categoryId but I want to get only latest version of each definition against a category.

DataEntities data = new DataEntities();

Category cat = (from c in data.Categorys where c.ID == CategoryID select c).First();

IList<definition> defintions = (from d in data.Definitions.Include("Versions") where d.Category.ID == cat.ID select d).ToList();

IList<dynamicforms.data.version> versions;

if (defintions.Count>0)

{

versions = defintions.SelectMany(d=>d.Versions).ToList();

Grid.DataSource = versions;

Grid.DataBind();

}

If I need sub query How I have construct and use subquery in this code

Your early reply will be highly appriciated please.

How to copy the selected tree node along with its children and paste the same

I have been searching the net for 2 months now looking for info on how to do this. Can anyone point me in the right direction?
I have a vb.net program that used SendKeys to send ctrl+C and CTRL+V that was able to do this but I can't get that to go in VS2008 C#.

You're kidding right, 2 months wow!

There are a number of options
Context menu gives you right click on the node and deal with the menu option including ctrl C/V
Trap the keydown method on the node for the ctrl C, grab the node and set a flag that a node is copied, trap the next key down for the ctrl V and add the copied (cloned) node to the current selected node.

Yea really...I think if you look you will see some eariler posts going back a couple of months.

I have tried that...all I seem to get is the highlighted node I get none of the child nodes.
Originally this was a VB.net app done with VS2003 they used SendKeys CTRL+C and CTRL+V and it works fine.
Now I am trying to upgrade to C# using VS2008 and the above no longer works (don't get the child nodes)

Any other Ideas??

I guess you are copying the selected node and assuming the child nodes are in there - sounds like you need to get the whole structure of child nodes manually during the copy process.

I also presume you are copying the selected node to the clipboard and then pasting from the clipboard and accepting those limitations. This is useful only if you are moving off the app/form/control where you are copying from (and thereby losing the original structure). If it is inside your app why not grab a placeholder on the copy event and when the paste is done go and get the entire structure from the original node.

The way it worked in the old app was they were copying the selected node and pasting using the clipboard. This copies the selected node and all of its child nodes. (they were using the sendKeys CTRL+C and CTRL+V).

The few examples I have found on the net were just the simple copy and paste of the selectedNode.

I have also tried cloning but have not gotten that to work either.

If you have an example or a link to a good example I would be most greatful.

It seems like it should be a simple task but I guess if it was there would be some meaningful examples.

Why is that a problem? Surely you are storing your connection string in the config file. Or have you hard coded it in to the application itself?

You can have several connection strings in the same config file. You can design your application in such a way that it prompts the user to select which environment it wants to connect to and then fetch the appropriate connection string from the config file.

Assume you booked a Air Ticket for California. Now you have changed your mind and decided to go to Paris. What do you think, the same ticket will work? Sorry, just kidding. If you are changing the database, the connectionstring also needs to be changed either in config file or in every places where it is used.

I think what you are looking for is "localhost".

If you set the server name in the connection string to "localhost" it will connect to the SQL server running on the local PC.

You need to explain your question in more detail and explain what you are trying to do, your question is not clear at all.

My pleasure.

The reason that you didn't get any other good answers is because you question was very unclear and difficult to understand.

I'm not talking about the quality of your English (that's fine), but about how well you describe your problem. Next time you post a question, take the time to properly describe the situation you are in, the problem you are having, and what you are trying to achieve.

That will always be the case.
The only solution, that I can think of, there may be others but they escape me for now.

1. Try connecting using your stored connectionstring, catch exceptions and when the exception shows database absent
2a. Create a clone of the MS Server Connection Dialog and let the user 'find' the right server. OR
2b. Iterate over all available servers and do 1. above uon each one ntil you find the database, then modify the current connectionstring to match.

You might find it useful to read up on the ConnectionStringBuilder class for a fairly easy way to modify connection strings.
You might also want to download the SQLServer 2008/2005 Samples from Microsoft Download site for an example of cloning the dialog. If you do so an example will be found at YourDrive:\YourBaseDirectory\Samples\Engine\Programmability\SMO\ServerConnect\CS\ServerConnect.
In the Samples directory tree you will also find examples of how to find all available servers, so you can iterate over them, if you decide to do it that way.

Of course whichever way you do it, you will be faced with the problem of how and where to store the modified connection string. Smile | :)

Good Luck! Smile | :)
