Also be a little more specific: what's the purpose of that comparison? Find out that the person is really John Doe, find out who the person is (oh that's really something totally different, do you understand that?), identify object types by their (fixed) shape at different angles, etc...

Converting touch screen mouse events into normal mouse events

I recently picked up a windows tablet and I'm frustrated that certain games react very poorly to touchscreen input. For example, a single tap registers as moving the cursor to that position rather than clicking, a double tap is a single click, and holding a tap is a right click rather than a click and hold.

I'm curious how viable it would be to write a background utility that could trap touch screen events and then generate more traditional mouse events while enabled. C# is my preference, but if its necessary to do this in c++ or something I can adapt.

So I suppose what I'm asking is:

a) is this possible?

b) if so could someone point me in the right direction?

Thanks!

I would say that such a thing is not possible on a system-wide basis, because the tap events are "baked" into the OS, and to change them would require rewiring some very fundamental code.

It would be like trying to alter the mouse events on desktop Windows.

The difficult we do right away...
...the impossible takes slightly longer.

I am not sure how to do that or even if it is possible, but have you tried to see if you can change the Touch Actions[^] to achieve what you want?

Hi
How to control Windows Media Player.?
Example:
In one form, some buttons (play, stop, next, previous and volume control Trakbar) have.
Windows Media Player is playing ...
When we press a button, the Windows Media Player stops or when we press the play button, Windows Media Player continues to play music or when we press the next or previous buttons to change songs. Smile | :)

I am developing a application with a WebBrowser control that login to site, but it give security alert:

Revocation information for the security certificate for this site is not available. Do you want to proceed?

I want to that its automatically confirm this alert using code.

I find many question on this issue but they are not useful in my case.

You shouldn't attempt to confirm this automatically. This is a security notification for the user and you should not attempt to circumvent it because you will be hiding potential issues from the client.

Don't try to find code to hide the issue with the certificate. Instead, fix the issue with the certificate.

If the certificate really is valid, then there's a problem on the computers which are displaying the message. Fix that problem instead. There are some suggestions in this Microsoft Knowledgebase article[^] which might help.

There is no good reason to hide this error from your users.

Hi All,

I'm new to TDD. I need to return a DTO containing the the details of the Customers referenced by CustomerID in C# as given below.

The Output DTO should contain the following properties:

int CustomerID
String CustomerName
String[] Addresses

Given below are the data repository classes with properties:

Customer class
{
public int CustomerID {get; set;}
public string CustomerName {get; set;}
public int[] AddressId {get; set;}
}

Address class
{
public int AddressId {get; set;}
public string Street {get; set;}
public string City {get; set;}
}

Note: Should be a TDD approach

Please help me with sample code

Thanks in advance,
Ram

Use the RESTORE command and connect to the database server with an user that has access to do restores. (e.g. server admin)

You can just use the normal SqlConnection and SqlCommands to do that

Important Note: The path to the backup you provide are relative to the SqlServer. If it is not the same server as your application you need to copy the files to the server (or a network share?) first where the database server can restore the backup from.
