I am trying to get keyboard and mouse hooks. I am able to install hooks in my system and also get the hooks. But i am trying to get hooks from a particular application, so is there any way to get it or it is possible that when i am installing the hooks then i am able to install for a particular application only.
I am using the following url as a sample application.
http://www.codeproject.com/KB/system/globalsystemhook.aspx
Please help me..

If you are trying to install global hook,you have to know that .NET Framework doesn't support that  .You need a native DLL(based of MFC library for example),because .NET assembly doesn't support DLL exports(which are used for LoadLibary native function),required by the global hooks.Read bottom lines of this article.

ya i knw .NET Framework doesn't support this. I am using same dll and using this i am able to install hooks and also able to get the events on pressing of keys.
But i want to install the hooks for a particular application, so is there any method that give me this functionality or is there any way to get the application name on which we have pressing keys, so that i can do something on events if hooks comes from a particular application.

you can do this only by using native dlls.....
If you already installed the hooks successfully then the task is much simply accomplished by just getting the active application by getting the active window.
Get the handle of the ActiveWindow. you can refer this page.link[^]
Determine the application from the handle and map the current mouse and keyboard events to this application.
Have a Happy Coding.....

Hi,
In this code for example:
double Start =1;
double Jump =0.2;
double End = 2;
List<double> m_List = new List<double>();
for(double Num = Start ; num<=End;Num+=Jump)
m_List.Add(num);
i want to get the numbers 1 , 1.2 , 1.4 , 1.6 , 1.8 , 2
But im getting 1 , 1.2 ,1.4 ,1.5999999 ,1.79999999 ,1.99999999
How can i fix it?
(The numbers can be in 2e-04,300,6e-8 for example)

have a look at decimal[^] that might be better for you

you can use math() function to convert e.g 1.5999999 to 1.6 using math.ceil or math.floor

Hi,
How to pass parameters to a Access database using oledb provider and enterprise library. We used below code to update category table which has two colums ID and CategoryName. The code runs successfully without any errors but the table row remains unchanged. What could be the problem
Database db = DatabaseFactory.CreateDatabase("MyDemoConnection");
DbCommand dbCommand = db.GetSqlStringCommand("Update Category SET CategoryName = @CategoryName WHERE ID = @ID");
db.AddInParameter(dbCommand, "@ID", DbType.Int32,(int) 1);
db.AddInParameter(dbCommand, "@CategoryName", DbType.String, "Just a Change");
int i = db.ExecuteNonQuery(dbCommand);
<connectionStrings>
<add name="MyDemoConnection"
connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\db1.mdb;User Id=admin;Password=;"
providerName="System.Data.OleDb"/>
</connectionStrings>
It would be great if any one can redirect me to the exact way

Generally speaking, it is best to first save the excel file as a delimited text file, or xml file, in Excel itself.
If that is not an option, you could try to convert it in your application first, and only then try to import it into your database.
You can try to import directly from the Excel file, but the code will be sensitive to version changes of Excel (it will work for Excel 2003 but not for Excel 2007 for example)
Another option is ODBC.
My advice is free, and you may get what you paid for.

Well, if a network connection exists, you can use it. You can't just hijack another app to find it tho

Well, if its course work talk to your tutor, if its a task at work talk to your manager, and if its a job you bid for and won tell your client you are told lies and you have no idea what you are doing.

It's funny, your profile says your are from the USA.
Why I don't have a clue of what you are trying to achieve after reading your question?
Surely you master the English well enough to ask a meaningful question?

If you'd like the source code to do VOIP, I recommend going over to the job site and hiring someone to write it.

I have a repeater that I am dynamically generating controls for based on some DB data using a class inheriting ITemplate. I am currently generating a checkbox and a textbox for each row in the DB which is working fine. The problem is that I want the textbox to be invisible until the user clicks the checkbox corresponding to the adjacent textbox. I have wired up the click changed event, but I cannot access the textbox only the checkbox. Should I use a Delegate or some other method of enabling and disabling the visibility of the textbox.
