What's deal with
treeView1.Nodes.Reverse
'System.Windows.Forms.TreeNodeCollection' does not contain a definition for 'Reverse'
What's the trick to reverse enum a treeview?
Thanks

I need to remove nodes that don't hit a search query, and leave the nodes and their parents.

I am new to c# so please bare with me...and not laugh to hard at my question.
I can't get onto the MSDN site and since my help menu isn't working correctly I figured I would post my question here.
I was trying to see if there was a way to specify the precision while using double.ToString()? I have a double that returns to me a double with 10 digits after the decimal. I would like to just have it return 3 digits after the decimal.
Do I have to manipulate it using the string.Format or is there a way to do it in the ToString()?
Thanks in advance.

Try double.ToString("F"), which is uses the same format specifiers as String.Format.
[edit]Sorry, I missed the "3 decimal places" bit. As was pointed out, you want to do ToString("F3") instead.[/edit]

Thanks....i figured it was something simple, I just didn't think to put it in parenthesis  <doh>

Use the formatting string "F3" to get three decimals.
The String.Format method uses the same formatting style as the ToString method. String.Format("{0:F3}", f) produces the same result as f.ToString("F3").

Hello all,
i am new to C# and there is something i can't get to work, so i a requesting your help !
simple code :
namespace ConsoleApplication1
{
class Father
{
public Father()
{
System.Console.WriteLine("Build Father");
}
public void Something()
{
System.Console.WriteLine("Father : Something");
SomethingElse();
}
public void SomethingElse()
{
System.Console.WriteLine("Father : SomethingElse");
}
}
class Son : Father
{
public Son()
{
System.Console.WriteLine("Build Son");
}
public new void SomethingElse()
{
System.Console.WriteLine("Son : SomethingElse");
}
}
class Program
{
static void Main(string[] args)
{
Son s = new Son();
s.Something();
}
}
}
this simple code displays "Father : SomethingElse" at the console.
How to get "Son : SomethingElse" at the console without rewriting Son.Something() ?
Many thanks for your help !

Just declare SomethingElse as a virtual function in Father and override it in the Son class.
class Father
{
public virtual void Something() {...}
}
class Son : Father
{
public override void Something() {...}
}
|
|
|
|
|
just declare the somethingelse in father as virtual and override it in the son class.

In your other thread call File.Copy(). It will copy any files whther images or not.

I'm attempting to use DirectShow.NET to play movies on different DVD drives, with the following call:
hr = dvdGraph.RenderDvdVideoVolume( "f:", AMDvdGraphFlags.None, out status );
I have two DVD drives, E: and F:
Regardless of the path that I give RenderDvdVideoVolume, it always plays the movie on the first drive (E) and the flag bDvdVolInvalid is set true.
Anyone have any ideas? I'm using DirectX 9.0c, etc.
The call is basically just an interface call to the SDK, DirectShow.NET isn't injecting any other code. When I looked at some C++ examples:
WCHAR achwFileName[MAX_PATH] ;
LPCWSTR lpszwFileName = NULL ;
if (lstrlen(m_achFileName) > 0)
{
#ifdef UNICODE
lstrcpy(achwFileName, m_achFileName) ;
#else
MultiByteToWideChar(CP_ACP, 0, m_achFileName, -1, achwFileName, MAX_PATH) ;
#endif // UNICODE
lpszwFileName = achwFileName ;
}
AM_DVD_RENDERSTATUS Status ;
DbgLog((LOG_TRACE, 5, TEXT("Calling RenderDvdVideoVolume(<%s>, 0x%lx, 0x%lx)"),
m_achFileName, m_dwRenderFlag, &Status)) ;
HRESULT hr = m_pDvdGB->RenderDvdVideoVolume(lpszwFileName,
m_dwRenderFlag, &Status) ;
it looks like the string needs to be Unicode format, which is what a C# String is. Still, I wonder what requirements the API method actually has that C# isn't meeting.

I'm sure you've tried:
hr = dvdGraph.RenderDvdVideoVolume(@"f:\\<code>video_ts</code>", AMDvdGraphFlags.None, out status );
See:
Writing a DVD Playback Application in DirectShow[^]
The first parameter is the name of a directory that contains the DVD files. On a DVD disc, these files reside in a directory named VIDEO_TS.
At least it is USUALLY VIDEO_TS. See:
IDvdControl2::SetDVDDirectory[^]

THANK YOU!!!
And thank's for the links. That's the first time I've seen documentation that clearly says what the volume path actually should be.

Well, let's see if we can have some more. Now that it plays from the correct DVD drive, have you any experience playing a DVD over a network from a network mapped or shared DVD drive? It sort of works, except that the audio and video appear to be streamed in big chunks, so it's really choppy.
I came across something about DVD's and block streaming being a problem.  And there's this software called AnyDVD that seems to address that. More to figure out!

No problem. I just installed this thing called "AnyDVD", and it solved the problem!
Thanks again though, because without your help here, I and my client would be totally stuck. I owe you one!

Hello,
here is a function's signatures for 2 PowerPoint effects event handlers:
SlideShowNextClick(SlideShowWindow Wn,Effect ef)
The effect onNextClick is ef.
SlideShowNextBuild(SlideShowWindow Wn)
What is a current executed effect??
At the moment I have next implementation:
1. By handle SlideShowNextClick store next effect name ("xyz").
2. By handle SlideShowNextBuild execute my bussiness logic (for effect "xyz").
The problem occurs if the current slide has more than 1 effect on page and "go back" button will be used. ==> I can't catch "goback"-event, thus I can't be sure that my stored "NextEffect" is a next effect realy.
Is it possible to get number/name of current executed effect directly in SlideShowNextBuild handler?
Many thanks for your help.

I have 35 labels on a picture, if i set these to transparent they just asume the color of the form.
Now after googling for a while i found out that i should use drawstring but then i cant move the objects anymore which is like the whole point of the application.
Move code: (with event trigger @ the end)
I have been trying to get this to work for about 16 hours im going out of my mind,
I'd would make me very happy if someone could assist me in creating a way to display the text ontop of a picture and still be able to move them.
Thanks allot!
ps exuse my crappy coding skill.
private void movepic(object sender, System.EventArgs e)
{
newcoord = 0;
math = 0;
decide = "";
input = input.ToLower();
startcoord = 0;
substract = false;
//c = center (320)
if (input.IndexOf("c") >= 0)
{
decide = "c";
}
//r = right (640)
if (input.IndexOf("r") >= 0)
{
decide = "r";
}
if (input.IndexOf("-") >= 0)
{
decide = "-";
}
if (input.IndexOf("c-") >= 0)
{
decide = "c-";
}
if (input.IndexOf("r-") >= 0)
{
decide = "r-";
}
switch(decide)
{
case "c":
startcoord = 320;
input = input.Remove(0,1);
break;
case "r":
startcoord = 640;
input = input.Remove(0,1);
break;
case "-":
substract = true;
input = input.Remove(0,1);
break;
case "c-":
startcoord = 320;
substract = true;
input = input.Remove(0,2);
break;
case "r-":
startcoord = 640;
substract = true;
input = input.Remove(0,2);
break;
default:
break;
}
if (input != "")
{
math = int.Parse(input);
}
if (input2 != "")
{
newcoord2 = int.Parse(input2);
}
if (substract == true)
{
newcoord = startcoord - math;
}
else
{
newcoord = startcoord + math;
}
labelselect.Location = new Point(newcoord,newcoord2);
labelselect.BringToFront();
}
private void element1(object sender, EventArgs e)
{
input = textBox1.Text;
input2 = textBox2.Text;
labelselect = label121;
movepic(sender, e);
