Well, if the control is broken, if the events that should fire, do not, then your only other option as far as I can see, is to use a timer to check when one is changed, and then change the other, or use the keyboard events to detect when a keypress occurs on the control, and then from there, check if the selection has changed.

Your code sucks. I just wrote a sample project and it works just fine. Press a key to change selection and the beforeselect and afterselect events fire, with a keyup event in the middle.
If you want help here, it helps to post your code, so we can tell you where it is broken, although in this case, it's very simple. Hook up the event, and it will fire.

Thanks a lot for replying me.
My two trees worked with the following code.
private void sourcetree_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Up)
{
if(destinationtree.SelectedNode.PrevVisibleNode != null)
destinationtree.SelectedNode = destinationtree.SelectedNode.PrevVisibleNode;
}
else
{
if(destinationtree.SelectedNode.NextVisibleNode != null)
destinationtree.SelectedNode = destinationtree.SelectedNode.NextVisibleNode;
}
}

Please help.
Thanks

We have a WPF forum. What is the MVVM pattern ? I think we've become too obsessed with idiotic patterns that are used to try to be trendy. If a pattern does not suit your app, don't use it.

Hello...
I'm new to WCF. I'm working on a architecture where I need to convert my Business object class to Data Transfer Object class for accessing web service. At the same time I need to do the opposite. but I don't know how to this conversion?
Any help would be appreciated, specially with code sample.
Thanking in Advance
Johnny

I'd be astounded if half the point of WCF was not that it offers this type of serialisation for you. Even web services, which WCF will wrap, I believe, will do that for you.

Thanks for your quick response.
Actually i have to transfer the business object from my Desktop app to a remote WCF service .That's why
i think i have to convert my business object to DTO and vice versa.
How can i do this?
|
|
|
|
|
I don't know for sure, I just know that if you need to do any sort of conversion, then WCF only makes it harder to use a webservice, because I've written plenty of webservice clients and webservices, without ever having to do this.
Also, please don't cross post.

Hello Johnny,
converting a BO to a DTO is a manual task which has to be done by yourself and not by WCF. But there is a sweet library called AutoMapper (http://automapper.codeplex.com/[^]) I can highly recommend. Its a convention-based object-object mapper which can handle the BO-to-DTO mapping and vice versa for you. Take a look and enjoy
Greetings,
Tobias

hi, trying to add a .wav file to my project's resources, and play it through axWindowsMediaPlayer1.
Problem is i dont quite know how to tell the axWindowsMediaPlayer1 where the file is.
I have tried the following:
WindowsFormsApplication1.Properties.Resources.tune (tune being the wav file)
except now the player has a problem because of no file extension, and if i add an extension, it plays nothing.
WindowsFormsApplication1.Properties.Resources.tune.wav (plays nothing, you can see why)
any help would be appreciated, thanks.

I don't think this will work, I've only ever been able to get WMP to play files in the file system. Unless you can set up a web server and make it think it's coming from an online source.

In the Solution Explorer you can open the directory named Resources,click tune.wav.
Change its first advanced properties,so it would copy the wav file to the the directory where your program is.
axWindowsMediaPlayer1.URL = Application.StartupPath + "\\Resources\\tune.wav";
You can have a try.
My English is just so so,wish it can help you.

thaks for the replies, but is there anyway i can somehow pack the wav file into the program? i would rather it not be separate. thanks.

In C++ I can pass parameters by value/reference(using &).
If I create an instance of a class using the new keyword in C++, and pass the pointer pointing to it by reference (reference to pointer, e.g. MyClass &* ptr), is it the same as passing a ref type by ref in C#?
As in both cases, the callee can change the object’s state, as well as point/refer to other objects.
What do you think?
|
|
|
|

I think the only way to be sure is to write some test code. I suspect you are wrong, in that you can't dereference a reference in C#, I think that ref basically is worthless if it's already a ref type, it adds nothing.

Here you go:
{
string s="a";
log("s="+s);
doubleString1(s);
log("s="+s);
doubleString2(ref s);
log("s="+s);
}
private void doubleString1(string s) { s+=s; }
private void doubleString2(ref string s) { s+=s; }
outputs:
s=a
s=a
s=aa

I am working on a screen capture project that uses a global mouse hook. It works great.
currently when the user holds the right mouse button down for a time the cursor changes to a hand.
see below
[DllImport("user32.dll")]
static extern IntPtr LoadCursor(IntPtr hInstance, int lpCursorName);
private int IDC_HAND = 32649; /// IDC_HAND = 32649;///IDC_UPARROW=32516///IDC_CROSS=32515
private const uint OCR_NORMAL = 32512;
on event
private void setcursor()
{
IntPtr hcursor = LoadCursor(IntPtr.Zero, IDC_HAND);/// IDC_HAND/// IDC_UPARROW//IDC_CROSS
bool ret_val = SetSystemCursor(hcursor, OCR_NORMAL);
}
What I need is a LARGE CROSS
so I made these changes
DllImport("user32.dll")]
static extern IntPtr LoadCursor(IntPtr hInstance, int lpCursorName);
private int IDC_CROSS=32515; /// IDC_HAND = 32649;///IDC_UPARROW=32516///IDC_CROSS=32515
private const uint OCR_NORMAL = 32512;
private void Form1_Load(object sender, EventArgs e)
{
RegistryKey loadcursor = Registry.CurrentUser.OpenSubKey("Control Panel\\Cursors", true);
loadcursor.SetValue("Crosshair","%SYSTEMROOT%\\Cursors\\lcross.cur");
loadcursor.Close();
}
on event
private void setcursor()
{
IntPtr hcursor = LoadCursor(IntPtr.Zero, IDC_CROSS);/// IDC_HAND/// IDC_UPARROW//IDC_CROSS
bool ret_val = SetSystemCursor(hcursor, OCR_NORMAL);
}
am changing the poiter of the crosshair cursor the crude way !
dont now how to make it apply the rgistry changes. so that you dont
have re boot to make changes apply.
I would do it in the private void setcursor(),
but there is no system "large crosshair cursor".
only lcross.cur in windows/cursors.
AM I MESSED UP OR WHAT?
Thanks,
Regards.
P.S.
here is a link to the published project
it works great. Just want to put a little polish on it.
