Hi,
there are no provisions for limiting a thread's CPU usage.
You could throttle it yourself by adding some Thread.Sleep() calls.
On a multi-core CPU with N cores each thread cannot take more than 1/N of the available cycles, so on a dual-core a thread's maximum would be 50% anyway.

Dont ask all those ridiculous question out here.... If you have problem in executing any code or program, then you can post it here for rectification, but please dont ask for steps or How to..... Got it?
However, go to Google or MSDN and search for 'creating InstallShield in VS.NET 2008'. Hope this helps,

SAPI 4 has a sample in Visual C++ 6.0, a demo program called multivce (tts to direct sound) that enable the speech output to be in 3d, so that the speech output can be sent to different speakers. Can this be done using C# ? If it can please tell me how.
Thanks

If you are using a Visual Studio Setup Project, open the File System Editor. Right-clicking on the root node, you can select Add Special Folder->User's Desktop. Then, right-clicking on the folder content, you can select Create New Shortcut to add a shortcut to your application execurable file.

Hi all.
How can we use AutoCompleteCustomSource for a TextBox ?
I've searched Google , but I couldn't find anything special !
Could you guide me ?
Thanks in advance.

This will return an autoComplete TextBox with the Greek leters as custom source.
private TextBox CreateAutoCompleteTextBox()
{
TextBox result = new TextBox();
AutoCompleteStringCollection autoCompleteStrings = new AutoCompleteStringCollection();
autoCompleteStrings.AddRange(new string[]{
"Alpha",
"Beta",
"Gamma",
"Delta",
"Epsilon",
"Zeta",
"Eta",
"Theta",
"Iota",
"Kappa",
"Lambda",
"Mu",
"Nu",
"Xi",
"Omicron",
"Pi",
"Rho",
"Sigma",
"Tau",
"Upsilon",
"Phi",
"Chi",
"Psi",
"Omega"
});
result.AutoCompleteCustomSource = autoCompleteStrings;
result.AutoCompleteSource = AutoCompleteSource.CustomSource;
result.AutoCompleteMode = AutoCompleteMode.Suggest;
return result;
}

Thanks you very much DaveyM69.
But I have a MultiLine Textbox and it doesn't work on it.
|
|
|
|

Yeah - the built in autocomplete doesn't work with multiline. You'll need to 'roll your own' control to do this I think.

I'm trying to get an output array from a function in an unmanaged DLL into my C# application. I've already done some googling on this topic and while I've found some articles, none of the suggestions seem to work.
The DLL has a function prototype of
int GetData(int ID, float* Results)
The int that is returned is the length of the array
Internally to send the results back it does
Results=new float[length];
In my C# application I use a delegate to get the function results:
[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
private delegate int delGetData(int TagID, ref IntPtr Results);
I then try and retrieve the results and copy to a managed array doing this:
IntPtr data=IntPtr.Zero;
int Len=GetData(ID, ref data);
if(Len==0)
float[] results=new float[Len];
Marshal.Copy(data, results, 0, Len);
I always get an exception on the Marshal.Copy because the source (data) is null.
I have some control over the unmanaged DLL, any suggestions on how to get these to interface?
Thanks

Hi,
If data gives a NullReferenceException, something must be wrong in the unmanaged code; here are some possibilities:
1. a silly mistake, say "return 0;"
2. your function pointer (accepting the delegate) not being defined as __stdcall
3. something going wrong with parameter alignment on stack (native long=32 bit, managed long=64 bit;
native char=8 bit, managed char=16 bit); this assumes your post was showing simplified code only.
4. IntPtr needs a 4 or 8 byte pointer, depending on Win32/Win64; your native code must match that.
As far as P/Invoke goes:
I prefer to allocate arrays, structures, objects on the managed side, and somehow pass their pointer to the unmanaged world; this has the advantage of being a managed object from the start, and not requiring any copying, and the disadvantage it is difficult to achieve when there are unknown values, such as the array size.
However, you are using a delegate to pass results, so you could instead use two delegates:
- one to inform the managed world about the array size, and ask for an array pointer;
- one to signal the managed world the array has been filled.
Passing a pointer can be done in two ways:
- with the "fixed" keyword; simple, unless the array must remain fixed afterwards, as in your case.
- with the GCHandle class; don't forget to eventually free the handle!
BTW: you were using the ref keyword, "out" would have been more appropriate.
