You need to use something like this:
[DllImport("user32.dll")]
< Declaration of function in user32.dll to be used here preceded by static extern >
You have to declare each function you want to use in C# code in the above manner.Moreover you should write this code where you are declaring other variables of your class which is normally at the start of the class.
After that you can use those functions in your C# code. Keep in mind that all the types used while declaring function prototypes must be C# types and must not contains Win32 or other languages types.

Have you tried debugging the application to ensure the value you're sending to the database is the correct one?

Hi,
I am trying to write an windows application which needs to capture the text selected from other applications as well.
I would like to know how we can capture a text that gets selected when we double click on the mouse. When any text is selected in any of the applications (not only the application that i use to capture the Text value), i need to capture the text. For example when we select a text in the notepad, and double click the mouse on the application that i have created, then the text selected in the Notepad should be captured and displayed in my application. Is there a way to do this ...
Thanks in advance

There's a windows API called WindowFromPoint. If you p/invoke that, you can call GetWindowText ( another p/invoke ) to get the text of the window your mouse is under. How far that will get you, I don't know.
It's odd to me, I know of no commercial software that does this, but it gets asked for so often.

A textbox is a very nasty control. It draws itself outside it's paint message, so it's very hard to change how it looks.

Hi Sanjit.rajbanshi,
I have tested your code in Window Application (C#) after changing my AD name (sync.net). It's working fine. I have no problem with it. maybe. you are getting this error cuz you dont have the permission or you might put wrong AD name.
If your application is web application then you need to impersonate ur account.

I am using Client-server Architeture for my c#.net Window base Application.
For that I am using TCP Remoting.
How can I preserve Connection object?
means Only once Connection will establish while log in.and it will available
me through life time of application.

Singleton Pattern?
Been a while since I learned about it, but as I remember, it does the trick

Hello,
May be you can try to store that object using binary serialization and use it any time you want.
This is just one idea I want to share with you.

It's dangerous to assume that the connection will always be there throughout the life of your application. What happens if the machine at the other end is restarted? Your connection is no longer valid, and operations on it will fail.

Hi all
I am working in c#.net
in my project i need create report using dynamic sql (i.e. parameter is passed at run time )
e.g
select * from employee where m_month = "runtimepara1" and m_year= "runtimepara2"
can anyone help me
![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif) thanks for your time
|

Build your query like this:
string sql = "SELECT * FROM Employee WHERE m_month = @month AND m_year = @year";
SqlCommand cmd = new SqlCommand(sql, connection);
cmd.Parameters.Add("@month", theMonth);
cmd.Parameters.Add("@year", theYear);
Also, SELECT * is inefficient. You should specify the columns that you want to return.

But I think it's used in Crystal ReportGeneration
i USED Reportviewer control in C#.net(InBuild not Crystal report)
Is their are solution to pass parameter dynamically or same Solu is also used
plz reply me
Thank's
|
|
|
|

The example you were given, shows you how to pass parameters dynamically. Or, do you mean, pass which parameters to select, dynamically ? In that case, if you're building SQL, you just need to conditionally add the columns you want.

Hi all!
I want to change the height of a combobox in flat style, but I can't, Visual Studio 2005 resets the value back on a value depending on the used font size.
On a TextBox I can change the height (when property Multiline is false)
Has anybody an idea how I can afford this problem easily?
Thanks a lot
Jörg

Why you want a higher combobox?
You can create a new custom control... You have to put inside a Panel (with black borders), and inside the panel a combobox(properly aligned), and set no borders in the combo... Obviously, the background color of the panel and the combo has to be same. If you don't wanna to write a lot of properties, directly put only one property of type combobox(the combo) to access it from the form.
