It's only for structs, not for classes.
The only way of getting a rough estimate of the size of a managed object is by serializing it. The serialized size is actually bigger than the size in memory, but it can help you to spot who's taking memory.

 Hi,
I have to write a program to capture a usb barcode scanner,...
as you all know, when you scan a barcode, it acts like a keyboard & just sends the barcode text to the active window. all i have to do is just to write a program which runs in the background & captures those scanned barcodes to a text file and it would not sent it to the active window,.. it's like windows message intercepting for your own purpose.
i really apprecite if you can give me any sample code, or any clue.
Thanks in advance

You say it's acting like a keyboard, are you implying that it's using a generic Micorosoft Human Interface Driver?
/\ |_ E X E GG
|
|
|
|
|
yes i think so,
i didn't install any driver, by theway i have windows xp pro sp2.
it should be same as the usb keyboards.
|
|

|

Well then you can use some already documented APIs to interface with your device. I will post more details the open of business Monday.

Search the web (or codeproject) for keyboard hook, and you'll find what you look for. But probably it'll be hard to find something in C#, it's something that easier done in C++.

i had already programmed to capture frames at some specific intervals from the default webcam installed on the pc and i succeeded to transfer it but i need to know how to encode it before transmission and then on the other side to decode it not to halt the network and make the transmission able to be transmitted efficiently with network leaks or memory leaks take place.

Is there any built in function to reverse a string in c# if yes what is that?
|
|
|
|
|
What DR. GUI .NET (link[^])says about StrReverse equivalent: "None—use StringBuilder and loop to reverse by swapping characters in place."
Dunno about .NET 2.0 however.
Never forget: "Stay kul and happy" (I.A.)

No, there isn't.
You can convert the string to a character array, reverse the array, and then create a string from the array.

how are you dudes ?
How can i connect to online user using dial up connection on the internet by knowing his ip address ?
i mean if i have the ip address of one user on the internet but he uses dial up connection or DSL how can i connect to his pc using c#?
even if he is out of my ISP ( Internet Service Provider) on dial connection and if he is connected using DSL he is behind his router and his network configuration
i used this code
<br />
IpHostEntry myhost = Dns.Resolve(his ip address as string);<br />
IpAddress ip = myhost.addresslist[0];<br />
string[] aliases = myhost.aliases;<br />
ipendpoint remoteendpoint = new ipendpoint(ip,(Int32)10000);<br />
tcpclient myclient = new tcpclient();<br />
myclient.connect(remoteendpoint);<br />
is this code can connect to the users using dsl or dial up connection remotely ?
cause may be this code will not work cause when the user connect using dial up connection he takes virtual ip address from his ISP ( Internet Service Provider ) and if he is connected using DSL he is behind his router and network configuration.
The question is i didn't test this code with someone online on the internet but i want to know is this code can do the real work by connecting to the user at the specified ip address or no ?
please Help me with this
Please Reply to me please.
Thanks alot

You can connect to his machine IF AND ONLY IF his router and/or firewall is setup to let you connect to his machine. If not, he'll have to modify his router configuration.
The type of connection he's using doesn't make any difference what-so-ever. So long as he's connected to the Internet and using a valid IP and his router is configured to let you in, you can connect to his machine.

How can I detect mouse clicks outside of the application and then read the coordinates? I'm trying to create an application which pops up menu when clicked right edge of screen with the right mouse button.

To Detecte Mouse or Keyboard event outside your Application you need to use Hooking ther are many articles
at Codeproject about hooking one of them
Global System Hooks in .NET
[^]and look at HOW TO: Set a Windows Hook in Visual C# .NET[^]
if you want to get mouse position you can use
Cursor.Position

Hello.
While running a C# code I'm running a C method from a pre-compiled dll (LZO decompressor)
On some calls to this method I recive a memory exceptions assumed to be related with the garbge collector. Even using fixed memory pointers in an "unsafe" code section didn't solve the problem (very strange).
while(...){
try{
unsafe{
.
.
.
fixed(byte* Psrc = src, Pdst = dst, Pwrkmem = this._workMemory){
lzo1x_decompress(Psrc, SourceSize, Pdst, &outlen, Pwrkmem);
}
.
.
.
}
}
catch{
.
.
.
}
}
Calling the GC with GC.Collect() before the calling C function gave *less* memory excepetions but didn't solve the problem.
I decided to try to shut down memory managment while executing the C function.
Anybody know how to pause & resume the garbage collector ?
Anybody know how to solve this problem ?
The Exception beening thrown is "Object reference not set to an instance of an object." I assume this is bacause the garbage collector has moved one of the variables.

Doubtful, if it had a reference and the garbage collector moved it then the reference will refer to the new location.

Since you don't show the defintion of the src, dst and _workMemory I cannot tell what they are. However, normally the fixed statement is used like this:
fixed(byte* pSomeObject = &someObject) which also uses the & (address of) operator.
So, what exactly is no longer referenced that was once referenced?

src, dst & this._workMemory are all byte[] type arrays.
I have no clue what is no longer referanced as I inly have the dll, no source.

The GC *never* set anything but a WeakReference to null. The problem you describe is caused by trying to access a member of a variable that is null. Put an Debug.Assert(var != null) before the line that's throwing the exception and you'll understand what I mean.

hi
im doing parameterized query whereby the user has to enter id and password. im using access database to store my data and using visual studio .net 2003 to build my app. if the id n password match, data is retrieved. i need help to ensure that password typed is of the exact case as stored in database. that means, if password in database is hELLo23 the user cannot access if he types hello23. how do i do that?
second problem is how can i make it such that user types in password and the password appears like this ********?
finally, how do i let password in database appear in encrypted text so that it is impossible to see the password in text format? i read about hash... do i use that? can i have more details?
thanks! =)

Use StrComp Function this function can be configired to make Binary Comparison
For example
<br />
Select * From Customers Where StrComp('ContactName','anyNamE',0)=0<br />
The Third Parameter =0 which tell the function use binary Coparison (Case Sensitive) and we compare the return value
From function with zero which mean the two string are equal
To learn more about the function parameters and return value look at StrComp Function[^]

TextBox have Propert Called PasswordChar Set it to The Character you want instead of plain text in your case set
It to *

hi
i got error when i tried StrComp Function --> Select * From Customers Where StrComp('ContactName','anyNamE',0)=0. it says something about YourPassword is not in Parameter collection. indeed it's not there. this line is what i wrote in OKbutton click event: oleDbDataAdapter2.SelectCommand.Parameters["YourPassword"].Value = textBox2.Text;
well, i tried to remove that line, but what i typed in password textbox did not successfully sense correct password (eg. hELLo23) and retrieve data from Access and display. It's supposed to sense hELLo23 from hello23 or HELLO23 or any other inputs that are different from that (hELLO23) in my database.
i also tried to do this --> Select * From Customers Where StrComp('ContactName','anyNamE',2)=2 as msdn says write '2' for Microsoft Access only. Performs a comparison based on information in your database. but it seems no difference as writing '0'.
loading of data is fine if i do this --> oleDbDataAdapter2.SelectCommand.Parameters["ID_Number_"].Value = textBox1.Text;
oleDbDataAdapter2.SelectCommand.Parameters["YourPassword"].Value = textBox2.Text;
dataSet41.Clear();
oleDbDataAdapter2.Fill(dataSet41);
if(this.BindingContext[dataSet41, "Table1"].Count == 0)
{
MessageBox.Show("Error Occured");
textBox1.Focus();
}
the only problem is that it's not case-sensitive in password textbox and it shows data even though password case is not the same as db.
i just want to ensure that for password any wrong case will not let user have access to get the data.
thanks a lot!
