C# has no need of that funtionality.

If you want to be able to use classes, structs, etc. from other namespaces without having to refer to it fully each time use add the appropriate using directive at the top of the class file.

You may also have to add a reference to the appropriate assembly that contains the code. To do this, right-click on the project you wish to add the reference to and select "Add Reference...". The dialog contains various tabs that indicate where the assemby is.

Sorry, but what is the big deal about calling ClassName.Func1()?

It is better to package these functions up in to an appropriate set of classes. It provides better logical separation.

Hi All,

I need to display time in the following format:

7:40a (not AM/PM whole word just A/P in lowercase)

So how could I achieve this?

I think
string strDT = <datetime instance="">.value.toShortDateTimeString().Replace("AM","a").Replace("PM","p");
It can be a bad way but it's a simple way

Hi,
I have already used the Camtasia SW, but the file that create is very bulky, therefore I like to find some coding for .NET compatible SW.

I have found another SW called TerboDemo(7.5 trial version), which captures the screen as an array of screenshots, which also take big capacity. It saves in .tdp format.

Please help me to find a .NET cording.

Hi you.
You are saying about hierachical data, called master-detail data. You can completely do it.
First, you make a dataset contains two table: PURCHASE and PURCHASEDETAIL. And you also make an internal relation among two tables with a "PURCHASE.ID = PURCHASEDTAIL.pID" datarelation. See next.
Second, you assign Datagrid's Datasource into this dataset.
That's all. It is working like you want .
Hope my help.

Sending message to another process

I need to send WM_COPYATA to another process from a C# program. Is there a C# method (maybe a class) equivalent to the Win32 API SendMessage(HWND h, ...) ?

Thanks, Satips, but in fact it didn't help me. I'm converting a working MFC program to C# and the only thing I stuck on is sending WM_COPYDATA message to another process, and the article doesn't say which method or class I should use (maybe I should use interop ?). Thanks anyway.

You could simply use P/Invoke SendMessage using this[^] p/invoke declaration. To get the window handle of the other process, you can use Process.GetProcess to get the process object for the other process and then use the MainWindowHandle property to get the window handle.

You would also need to use the actual value of WM_COPYDATA (0x004A), as that enum doesn't exist in C#.

So, why did you change the signature of the Main method in the first place?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
