Hello!
I want to add description to my functions that users who uses them can know what's its work, Like .Net framework functions. For an example when we type MessageBox instruction we see some descriptions about that.
Please if you know about this Help Me.
Thank You.

How can I read a string from a database field byte by byte? the DataReader class has two methods that seem useful: ReadBytes and ReadChars. The problem is that the former method can't be applied to a field of type string and the latter one reads the string char by char, not byte by byte. It also seems that the default encoding used by ReadChars method is unicode.
Notice that I don't want to read the bytes from a filled dataset, because after filling the dataset by a DataAdapter, there is a change made to the string that've been read.
Please help!

I think that what is happening is that the bytes are being altered because they are being stored in different ways to how .NET wants a string. If you really need the bytes then you are going to have to store the bytes in the first place.

And when i write the string to a file, it doesnt get the newline bit right, you just get a bar.
So how do i get it to do a new line. (I would REALLY like to do this without having to do WriteLine every time i need a new line).

Shouldn't you use \r\n instead?

The correct way to do this is use Environment.NewLine as it will generate the correct newline sequence for the current platform.

I have create a panel and then place a listBox control. I want to read a text file and place it into the listbox:
***************************************************************
listBox1.Text=" ";
listBox1.Location = new System.Drawing.Point(16,16);
listBox1.Size = new Size (320,220);
listBox1.BackColor = Color.FromArgb(255, 255,255);
panel1.Controls.AddRange(new Control[]{llistBox1});
// Open the file
SR = File.OpenText(@myFile.Text);
// Loop trough each character in the file
while((FileChar = SR.Read()) != -1)
{
// Display the text in the TextBox
listBox.Text += Convert.ToChar(FileChar);
}
// Close the reader
SR.Close();
}
****************************************************************
the above does not displays the text however if I use a labe then it works but I can not sroll the text once is displayed in the labe control.
Is there a better way to display the TXT in a list or label contrl?

Well, i've just been doing this kind of stuff, if you want to add a line of the file to your list box then maybe you could:
StreamReader SR;<br />
<br />
FileStream FS = File.Open("location of file", FileMode.Open, FileAccess.Read);<br />
<br />
SR = new StreamReader(FS);<br />
<br />
listBox.Items.Add(SR.ReadLine());<br />
Then just keep doing that until you get to the end of the file, i'm too tired to think of the code right now, i'm only still up cus i'm watching children in need 
and dont forget to close and null your StreamReader

The code seems to work right
**************************************************
StreamReader SR;
FileStream FS = File.Open("myFile.txt", FileMode.Open, FileAccess.Read);
SR = new StreamReader(FS);
while((FileChar = SR.Read()) != -1)
{
viewS.Items.Add(SR.ReadLine());
}
SR.Close();
****************************************************
but the first character in every line is truncated.
any idea?

Then it DOES NOT work right. Do as the other person suggested. You can't will the CPU to do something.

Hi,
I am kind of new to C# and in my app I want to call a Win32 Dll(say TestController.dll)...
The Dll fn goes like:
<br />
TESTCONTROLLERDLL_API int fnGetDiagnosticsData(int iscrn,int* iWindowsMonNo ,int * itype,char * cSerialNumber,int * len)<br />
{<br />
int ireturn;<br />
.....<br />
return ireturn;<br />
}
In my C# calss to call this dll, I refferd to some articles in google that suggested me to do as:
public class ControllerTest<br />
{<br />
private int iScreenNumber=0;<br />
[MarshalAs(UnmanagedType.I4)]<br />
private int iWindowsMonNo = new int();<br />
[MarshalAs(UnmanagedType.I4)]<br />
private int itype = new int();<br />
[MarshalAs(UnmanagedType.I4)]<br />
private int iLen = new int();<br />
[MarshalAs(UnmanagedType.LPStr)]<br />
private StringBuilder szSerialNumber = new StringBuilder(100,100); <br />
[DllImport( "TestControllerDll.dll", CharSet = CharSet.Unicode )]<br />
public static extern int fnGetDiagnosticsData(int iscrn,[MarshalAs(UnmanagedType.I4)]int iWindowsMonNo ,[MarshalAs(UnmanagedType.I4)]int itype,[MarshalAs(UnmanagedType.LPStr)] StringBuilder cSerialNumber,[MarshalAs(UnmanagedType.I4)]int len);<br />
......<br />
<br />
fn call:<br />
int iControllerNumber = fnGetDiagnosticsData(iScreenNumber,iWindowsMonNo,itype,szSerialNumber,iLen);<br />
But I am getting Null Pointer exception during function call...Where am I going wrong?????

I'm not an expert in PInvoking things, but something that caught my eye was:
int* iWindowsMonNo -->> [MarshalAs(UnmanagedType.I4)]int iWindowsMonNo
You have a pointer to an int, but on the other side you pass an int value. I suspect that iWindowsMonNo is set to 0 because the API expects to fill it. use ref int
The same goes for the other pointer types.

Hello,
I have FormMain, which launches FormA and FormB. FormA launches a dialog box, and that dialog locks other windows. Meaning I can't access FormMain nor FormB. Is there a way of making it work in such a way that I can access FormMain and FormB, but not FormA?
Thank you.

If FormA is opening a modal dialog box it will block access to all the other dialogs in your app until it's closed. AFAIK there's no way to create a dialog that's modal to it's parent, but not it's grandparents or uncles.

From the .NET Windows Forms MSDN article "Displaying Modal and Modeless Windows Forms":
A modal form or dialog box must be closed or hidden before you can continue working with the rest of the application.
To do what you want, you need a hack that allows your dialog to show in a modeless state and, while it shows, prevent FormA from receiving focus; that is, when FormA gets focus, the dialog steals it. For example, put the following code in FormA:
private void FormA_Load(object sender, System.EventArgs e)
{
Dialog d = new Dialog();
this.Activated += new EventHandler( d.FormA_Activated );
d.Show();
}
and the following code in your dialog class which I've ostensibly named Dialog:
public void FormA_Activated( object sender, EventArgs e )
{
this.Focus();
}
This will let the dialog window steal the show from FormA while it is opened and allow you to play with the main form and FormB.

I'm looking for a faster way to determine AD inheritance. Example: User object "JDOE" is a member of security group "Test Group". "Test Group" is a member of "Test Group 2". The "JDOE" object does not show as being a member of "Test Group 2" exclusively, so a recursive search is the only way I've been able to figure it out. Problem with this is that it takes about 1 second per query -- if the user object belongs to a complex network of groups it takes a second for each group.
I a method that given the user object and group object, it will call itself for each group that its a member of recursively. In my case I belong to 14 groups, it had to query 23 group objects before it found "Test Group 2".
I may even be going about this the wrong way; perhaps AD is the wrong tool for the job. Any suggestions?
