My English is not good.
But I mean something like that:
int count(POINTER head)<br />
{<br />
return head!=NULL ? count(head->next)+1 : 0 ;<br />
}
But not to return the value. I WANT TO DISPLAY THE VALUE.(and this is difficult)
|

Where do you want to display it? In a window? on a command line?
|
|
|
|
|
|
Console.WriteLine(myList.Count(myList.FirstNode))
seriously, you couldnt work this out? Swap to a different course while you still can.

It is a Data Structure work J4amieC. Anyway thank you.

Hi folks,
I have project writing rich text document on metafile using GDI
Now I'm trying to make it using GDI+
Problem: I can't draw it precisely!!
Test sample: create metafile 10x10 inces, draw strips 10, 9, 8 inches long:
<br />
RectangleF frame = new RectangleF(0f, 0f, 10f, 10f);<br />
Metafile mf;<br />
Graphics g1;<br />
<br />
using(Graphics gr = CreateGraphics())<br />
{<br />
IntPtr dc = gr.GetHdc();<br />
mf = new Metafile(@"c:\inch.emf", dc, frame, MetafileFrameUnit.Inch, EmfType.EmfOnly);<br />
gr.ReleaseHdc(dc);<br />
}<br />
g1 = Graphics.FromImage(mf);<br />
g1.PageUnit = GraphicsUnit.Inch;<br />
g1.DrawLine(Pens.Green, 0F, 1F, 10F, 1F);<br />
<br />
g1.DrawLine(Pens.Green, 0F, 3F, 9F, 3F);<br />
g1.DrawLine(Pens.Green, 0F, 5F, 8F, 5F);<br />
g1.DrawLine(Pens.GreenYellow, 1f, 0f, 1f, 10f);<br />
g1.DrawLine(Pens.GreenYellow, 3f, 0f, 3f, 9f);<br />
g1.DrawLine(Pens.GreenYellow, 5f, 0f, 5f, 8f); <br />
<br />
g1.Dispose();<br />
mf.Dispose();<br />
Strips are shorter than needed!!
Using other units (Milimeter, Pixel, Point, Document) produces different results - all invalid
Question: how to create precise EMF - with definite size

Hello, I am presented with the following problem and have tried desperately (over 12 hours) to solve it:
I have a string say "011010101" and I want to parse this string based on a table of values:
i = 0
m = 011
k = 10
e = 101
I want to construct an algorithm that will go through the string above and parse it assigning each value to their corresponding table value. Looking at it, I know that the string would become "011" , "0" , "10" , "101" which for this example would be "mike" in that order. Since "i" is the first thing I check, my code tries to form "0", "11010101", and nothing else will get extracted. I don't need code, but maybe some concepts I could build off of? Any help would be greatly appreciated.
I love to program!

A few thoughts:
if i=0 and m=011 how do you determine, when parsing, that a value of 0 is 'i' or the start of 'm'? The answer is that you need to have a defined way of making each value unique. A pointer for you would be to base your 0's and 1's from morse code, where this uniqueness is enforced - also morse (in case you dont know) is made up of dots and dashes - very fitting with your 1's and 0's
Ok, onto parsing the string - take a look at StringTokenizer's - there are at least two articles here on CP about the principle - and it is basically what you want - in (unwritten) code;
StringTokenizer st = new StringTokenizer("011010101");<br />
string convertedString = "";<br />
while(st.HasMoreTokens)<br />
{<br />
char nextChar = st.NextToken();<br />
convertedString += nextChar;<br />
}

This problem is potentially non-trivial.
There are two things your forgot to specify. The first is whether there can be more than one correct parsing for each string. For example, your string parsed to "mike", but (with the right additional codes) it could also have parsed to pratically any other alphanumeric output. This is key in determining when and how the algorithm should terminate. The second problem is one of scope. How long is the input string and how big is the table of values? The way the algorithm will work is to search through the space of ALL POSSIBLE parsings and output those that complete. Clearly, the bigger your input string and lookup table get, the more the chances of seeing a 'combinatorial explosion'.
If you answer these questions, I will help you write the algorithm. Please let me know if you are comfortable with embedded recursion, or your pefer iterative processes. The former is much more elegant, but with big inputs could create memory problems.

I prefer embedded recursion. There can be more than one correct parsing for each string, and for this example, the table is limited to the alphabet (lower-case and upper-case) and also '\n', ' ', and '\t'.

Hi Everyone,
If anyone could help me out i'd really appreciate it because this problem is really holding back the project. I'm getting the dreaded
Source File: c:\windows\microsoft.net\framework\v1.1.4322\Config\machine.config Line: 198 problem
which i'm pretty sure one or two of you might be familiar with seeing as there are threads on it all over the internet. The reason i'm posting this is because i've tried every solution on the threads i've seen and none work. Restarting the computer, adding a blank space to my web config file, turning off indexing service (it wasn't on in the first place), replacing the .DLL's with ones from their main build, clearing out the VS Cache and rebuilding. None of which worked, still the same error when i try to run my web project which leaves me at a virtual standstill as everything else i need to develop is dependent on this.
If anyone has a solution which is either a working variation of one of the above or a different way you found to get your web project back up and running i'd very much appreciate if you'd share it as i can't afford the time being wasted trying to find out whats wrong right now.
Cheers

Can anyone tell me please if its possible to bind a datagrid to an array of
objects (defined by me) so that when i update the contents of the array, the
data grid updates its display.
Any tips would be greatly appreciated.

Hi
Please could someone help me to convert the following to Visual Basic.. or alternatively post a table driven version
It is a CRC16 algorithm using the polynomial (x16 + x15 + x2 + 1) used for very short strings.
I think (not sure) a test string of "123456789" should generate a hex checksum of: BD3B
Tks
Richard
static unsigned BitsSet (unsigned char ch)
{
unsigned n;
n = 0;
while (ch)
{
n += (ch & 1);
ch >>= 1;
}
return(n);
}
unsigned CRCof (const char *message, unsigned len)
{
unsigned i;
unsigned crc;
unsigned char k;
crc = 0;
for (i=0; i<len; i++)
{
k = (unsigned char)(message[i]) ^ crc;
crc = (crc / 256) ^ (k*128) ^(k*64);
if ((BitsSet(k) & 1) != 0)
crc ^= 0xC001;
}
return(crc);
}

Hi all,
I'm using ftp with the command "NLST *.*\r\n". After I send this command I get a reply:
"226 Transfer complete". I just want to get the file list, the weird thing is that
Sometimes the command works and sometimes doesnt.
The commands: USER, PASS, CWD and PASV work FINE before "NLST" command.
Any idea why?
thanx

I want to bind a ComboBox with a DataSet by supplying a datasource and
also want to specify ComboBox.valueMember and ComboBox.DisplayMember in a
windows form in C#. What i m trying is below the piece of code but i m
not getting the required result;
ComboBox1.DataSource = DataSet1;
ComboBox1.DisplayMember = "StudentName";
ComboBox1.ValueMember = "StudentID";
How to Bind ComboBox1 with DataSet1 ? Please correct the above code
snippt.

Try this snippet. I think you simply didn't bind to the Table, rather than the data set.
DataSet ds = new DataSet();
DataTable t = new DataTable("Students");
t.Columns.Add("StudentID", typeof(int));
t.Columns.Add("StudentName", typeof(string));
ds.Tables.Add(t);
for(int i = 0; i < 5; i++)
{
DataRow r = t.NewRow();
r["StudentID"] = i;
r["StudentName"] = "Test Student " + i.ToString();
t.Rows.Add(r);
}
comboBox1.DataSource = ds.Tables[0];
comboBox1.ValueMember = "StudentID";
comboBox1.DisplayMember = "StudentName";Access the selected value:
private void comboBox1_SelectedIndexChanged(object sender, System.EventArgs e)
{
MessageBox.Show(comboBox1.SelectedValue.ToString());
}
|
|
|
|
|
you need to add more qualification.
ie.
ComboBox1.DataSource = DataSet1.Table
or
ComboBox1.DataSource = DataSet1;
ComboBox1.DisplayMember = "Table.StudentName";
ComboBox1.ValueMember = "Table.StudentID";
Cheers

G'day folks,
I am stuck on a form design problem which I just cant seem to find any solution. I have an application (Parent Form) which requires another window (child form) to be open in a modeless mode (using Show()) and whose TopMost property is set to true. My problem becomes that if I switch applications in the taskbar, say from my application to Outlook (running in maximized mode), the child form still stays on top of Outlook. This is because the child form is set to TOPMOST being true.
One solution I had was to use the Deactivate and Activated event handlers for the parent form. In the Deactivate event handler I setup so that the child form would become invisible and in Activate Handler the child form would become visible. I didnt realise that once the parent form become active it will then make the child form visible thereby the child form become the active form thus firing the Deactivate handler for the parent form. Therefore getting stuck in an infinite loop of child form appearing and disappearing.
There has to be a solution since when the find window is open in notepad and another application is active the find window from notepad doesnt dominate.
Can anyone point out what mistake I am making, I realise this has to be a very elementary mistake.
I would really appreciate any feedback.
thanks
Vee

Don't use the TopMost property which is 'absolute', but the Owner property which describes a 'local order' in your application's forms set.
