Hi,
I am trying to use a C# Windows Forms application as a DDE Client.
At present I'm using the follwing code to initiate a session with the DDE Server...
ushort app = GlobalAddAtom(Marshal.StringToHGlobalAnsi(appname));
ushort topic = GlobalAddAtom(Marshal.StringToHGlobalAnsi(topicname));
this.packedParam = PackDDElParam(WM_DDE_INITIATE, (System.IntPtr)app, (System.IntPtr)topic);
SendMessage(dtaProcess, WM_DDE_INITIATE, Process.GetCurrentProcess().MainWindowHandle, this.packedParam);
This should return a WM_DDE_ACK message to the main thread as follows...
protected override void WndProc(ref Message m)
{
\\WM_DDE_ACK = 996
if (m.Msg == 996)
{
MessageBox.Show("");
}
else
{
base.WndProc (ref m);
}
}
I do not receive the WM_DDE_ACK message. Also, the PackDDElParam method (user32.dll) returns a negative value. Is this correct?

You'll have to go to the article that you downloaded it from, scroll to the bottom of the page and you'll find a discussion board just like this one. Post a question asking for additional information there. Articles are, for the most part, supported by the people that wrote them.

when i use procedure
CommandType is procedure
and then run ExecuteNonQuery()
the return value of ExecuteNonQuery() is always -1
so the return value of ExecuteNonQuery is useless when use procedure?
|
|
|
|
|
It executes the query and just return the no of rows affected.
|
|
|
|
|
|
Hai
For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.
For more information See
SqlCommand.ExecuteNonQuery Method[^]
|
|
|
|
|
|
the procedure execute correctly and the data in DB changed.
but the return value is -1
why?
return value just useful when execute sql query?

I have a parent class, Base with 2 child classes, Child1, and Child2.
Base has a public int iNo. I init Child1 from another class. So Child1 inits Base.
Now, in Child1, I set Base.iNo = 10. Then i create the second child class, Child2 from Child1. Now, in Child2, when I call Base.iNo, i don't get 10.
I know the problem is that the child classes works with 2 seperate instances of the Base class, but how can i resolve this.
i want both child classes to inherit from the same Base instance. How do i do this.?
Thank you

You inherit a class, not an object. Child1 and Child2 only inherits the definition of Base, Child1 objects and Child2 objects still are separeate objects. It's the same way as if you have two separate Base objects, they each have there own set of members, although they come from the same class.
If you want to share a member across objects, you have to declare it as static.

Thank you very much, I never thought of static variables...

I have a C# Windows Forms application, where the executable really has to be small. It has about 5 or 6 forms, and the executable size is about 230 KB. By toggling the show all files in the Solution Explorer in Visual Studio, I can change the Build Action from Embedded Resource to None for the .resx files generated by the designer. With this, I shrank the EXE size to 100 KB.
My forms are not Localizable, and I haven't included any graphic files directly. The ImageLists I use are loaded from a bitmap strip with code, and not in the designer.
My code as it is doesn't break without the .resx files, but I wonder if there are other situations where they are used that I'm not aware of.
So, does anyone know?

Download, install and read the docs for the DirectX SDK. It has sample code.

Instead of the quite bulky DirectInput you can simply P/invoke the joy* functions. I've done this to support a footswitch that's behaving like a joystick and it works well.
THis MSDN article[^] might help you.
