I'm not familiar with MathLab but if you're using a mathlab API in a WinForm application you can choose not to show the Form(s) in the taskbar by changing the property ShowInTaskbar to false.

matlab is software he has installed..

ShowInTaskbar doesn't work here.. i think the only way is to minimize your windows to the tray menu..
search in google for a minimize applications to tray menu app or code yourself a program that does it..

Hi all, Sorry for the misunderstanding.
I have Matlab which is a program I installed.
The program have an option to open sub windows from the main window (lets say I know the names of all sub windows).

I want to build an exe file that when I run it , it will hide all the sub windows from the taskbar.

Hope I was more clear now and I soory again for not explaining myself before.

Hi pal,
Thanks. I saw the code.

This code hide the whole window so you can't see it on screen. What I want is to hide the window only from the task bar but still to see it on the screen itself.

Thanks.

It's kind of difficult to tell what's wrong just by reading the info you provided.. And your odds of getting help is probably better in the ASP forum.

detect javascript code for google ad sense

Hi

using c#.net i want to detect whether there is any javascript code present on the webpage for google adsense.

please tell me about the javascript code for the google adsense

Thanks

If you want to have a look at what the javascript looks like, you've got two options

1) Find a site that uses google adsense and view it's source (search for google_ad_client in the source)
2) Sign up for a adsense account, and request the javascript snippet yourself

As I say in (1) searching for "google_ad_client" within a script tag should probably be enough

Hi benjymous

Thanks for your reply

well i am also thinking about your 1st option
so are you sure if a website is running google ad sense then it should contain the keywords like "google_ad_client" ?????

Thanks
Anil Veeraghattapu.

benjymous30-Sep-09 1:04

Well, their javascript block has been formatted like that for a good few years, so if they changed it, it'd probably break all the sites using adsense, so it's a fairly safe assumption that it won't change, but it's never guaranteed!

How to define an inline array of a contstant size in a C# structure

Hi,

How to define an inline array size inside the stucture.Sample code i'm attaching the code block.
I'm using MarshalAs unmanaged it's working fine.

[System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential)]
public struct tPacket {    
/// WORD->unsigned short    
public ushort word1;    
/// WORD->unsigned short    
public ushort word2;    
/// BYTE->unsigned char    
public byte byte1;   
 /// BYTE->unsigned char   
 public byte byte2;    
/// BYTE[8]    [
System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.ByValArray, SizeConst=8, ArraySubType=System.Runtime.InteropServices.UnmanagedType.I1)]   
 public byte[] array123;}

And i used a struct which has a create method that fills out the array but it thow an error

[System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential)]
public struct tPacket {    
public ushort word1;    
public ushort word2;    
public byte byte1;    
public byte byte2;    
public byte[] array123;   
public static tPacket Create() {       
  return new tPacket() { array123 = new byte[8] };    }}

please help me.

Mahesh

Hi,

some comments/questions:

1.
if you get an exception, you should provide all the information about it.

2.
with a using System.Runtime.InteropServices; statement at the top, you don't need to fully qualify all the Marshal attributes.

3.
why do you define your struct twice? and differently?

4.
most often a struct gets a constructor, taking some parameters, and initializing all members. So you don't really need a Create() method.

5.
your code, and several variations on it, work for me. as in:

[StructLayoutAttribute(LayoutKind.Sequential)]
public struct tPacket {    
	/// WORD->unsigned short    
	public ushort word1;    
	/// WORD->unsigned short    
	public ushort word2;    
	/// BYTE->unsigned char    
	public byte byte1;   
	 /// BYTE->unsigned char   
	 public byte byte2;    
	/// BYTE[8]
	[MarshalAsAttribute(UnmanagedType.ByValArray, SizeConst=8, ArraySubType=UnmanagedType.I1)]   
	public byte[] array123;

	public static tPacket Create() {       
		return new tPacket() { array123 = new byte[8] };
	}
}
...
	tPacket p=tPacket.Create();
	for (byte i=0; i<8; i++) p.array123[i]=i;

6.
For readability code needs indentation. And PRE tags tend to preserve such formatting.

Smile | :)

Hi,

Thank you for our reply.

Actually i don't use the MarshalAs attribute to declare the array size in the structure.
And i want to read the 48 byte of data from the file.
and allocate the 48 byte of data into my structure.
the structure member break off will be

UInt16
UInt16
Byte[3] ==>3 Byte data-->This is my array to hold the 3 byte of data
Byte[3] ==>3 Byte date-->This is my array to hold the 3 byte of data
UInt16
UInt16
1 Byte
UInt32[8]==>32 Byte data-->this is my array to hold the 32 byte of data
1 Byte

But at once shot i want to copy my structure.
for the i used Marshl

But now i'm not to use the marshal
i have to use the BitConverter Class

using that how to copy my struture.

With Regards
Mahesh

Hi,

1.
without Marshal attributes any array embedded in a class or struct will be a reference, not the actual data (so it takes 4 or 8 bytes for Win32/Win64); so you need ByValArray and SizeConst.

2.
Your Int32 array is badly aligned; when a data item isn't naturally aligned, there will be a performance hit. If you can freely choose the struct layout I recommend:
- either to move the largest types first (longs, ints, shorts, bytes)
- or to explicitly add padding bytes so each element aligns on its natural boundary (i.e. each int is at an offset that is a multiple of 4).

Hi,

Is it possible copy by using BitConverter class

With Regards

Re: How to define an inline array of a contstant size in a C# structure

Luc Pattyn30-Sep-09 3:49

No.
BitConverter converts predefined value types (boolean, char, int, double, ...) to/from bytes or another predefined value type, as should be clear from the documentation. It does not handle user-defined structs nor arrays.
