unfortunately there is no similar code for octal or binary, things people around here seem to want often.
|
|

|

Yeah, that's probably why I've stuck with Convert - only one thing to remember!
There's been few times binary literals would have been useful too...

hi,
I developed windows application. In that I used web service. with use of web service I am fetching data from database and stored it into the cache.
cache contains datatable which contained data that comes from the database through web service. Now I want to update the datatable which is stored into the cache. I dont want to update the original database values.

Hi,
I used the delegate, Microsoft.Office.Interop.Excel.DocEvents_ChangeEventHandler, to track the changes in excel workbook.
Excel.DocEvents_ChangeEventHandler EventDel_CellsChange;
EventDel_CellsChange = new Excel.DocEvents_ChangeEventHandler(CellsChange);
xlSheet1.Change += EventDel_CellsChange;
It executes whenever the cell content gets changed.
But its not handling the automatic changes like function changes. Its handling only manual changes.
For example,
A1=10
A2=20
A3=SUM(A1,A2)=30
If A1 value changes to 15, then A3 changes to 35. I'm able to handle the change in A1(15), but couldn't able to retrieve the A3 cell changes. Please guide me to handle the automatic function changes.
Thanks in advance..

Hi everybody,
I have an tool that reads an file. That file has for example the follow content:
²{öï#°ÿùpO¬[ÿùpO¬ÿùpO¬¿ÿùpO¬ñÿùpO#ÿùpONÿ
I would like to search for repeated character combinations like the bold characters. The character combination ùpO repeated 6 times.
I would like to return some top 5 with the most repeated character combinations. Something like this:
ùpO : 6 times
xyz : 5 times
ab4 : 3 times
ab : 2 times
66 : 2 times
This is the code that reads the file:
string path = @openFileDialog1.FileName;
try
{
using (FileStream fs = File.OpenRead(path))
{
byte[] b = new byte[1024];
UTF7Encoding temp = new UTF7Encoding(true);
while (fs.Read(b, 0, b.Length) > 0)
{
textBox1.Text += temp.GetString(b);
}
}
}
Thanks!

if you want to clculate how many each char repeat you can use this:
string[] s;
s=File.ReadAllLine(@"file name.txt");
int[] c=new int[255];
for(int y=0y
|
|
|
|
|
I dont whant to count each character. I would like to discover some repeated character combinations.
|
|
|
|

string s="xlstxtjpgxls";
string[] f = {"xls","txt","jpg" };
int[] x=new int[f.Length];
for (int y = 0; y < f.Length; y++)
{
for (int i = 0; i < s.Length; i++)
{
for (int j = 0; j < f[y].Length; j++)
{
if (f[y][j] != s[i + j])
{
break;
}
if (j == f[y].Length - 1)
{
x[y]++;
}
}
}
}
for (int g = 0; g < f.Length; g++)
{
Console.WriteLine(f[g]+":"+x[g]);
}
Console.ReadLine();

Well, I'm sure there's a better algorithm for this, but here's one off the top of my head:
Note that this is NOT an efficient algorithm, and will NOT earn you any prizes if this is a school assignment (And if that's the case, keep in mind your teacher may be reading this).
1. Keep a string:int dictionary of substring:count
2. Loop through each character:
a. Looping from 2 to your maximum substring size (Say, 5)
i. Grab the substring of that length from the current position
ii. Add/increment it in the dictionary
3. Look through the dictionary keys:
a. See if the key is a substring of any other keys, with an equal count... If so, just delete this key.
Grab 'em, sort 'em, and display 'em...
If you want a better algorithm, you could try posting this in the Algorithms forum... I would guess there are at least a dozen formalized and documented algorithms to handle this, with all sorts of fancy names, that the folks there could point you to.

Hi,
I am developing a scripting tool in which I want to compile and execute the code in MEMORY, not as an executable file. But in there I need to redirect the console output to a Richtextbox and input to a simple textbox.
Example:
The script code is like this
public class Script
{
public static void Main()
{
Console.WriteLine("Hello World");
Console.ReadKey();
}
}
When I compile and execute in memory I want to print "Hello World" in a richtextbox and input the key from a textbox to terminate the application.
How can I accomplish it? I know how to redirect input/output if it is an executable file, but I don't know how to do the same for in-memory execution. Can anyone please help me?
|

What is the benefit you are seeking by compiling and executing in memory? Does it outweigh the risks of potential security vulnerabilities this exposes?
If this needed, why compile an entire application, just use the particular method that is necessary for your functionality.

That is not the point. OK instead of in-memory execution I invoke the entry point function from the compiled assembly. But there also how would I redirect the console input output to a textbox or richtextbox?

You don't. Execute the method from the assembly, get the output, then assign it to the textbox in your application.

Sorry, I didn't get that.
If the script has a line like:
Console.WriteLine("Hello World");
then how would I get the output and assign to the textbox? That entry-point function is not returning any string. If I am wrong please correct me with some example.
And also what about
Console.ReadKey() or Console.ReadLine(...) ?
Thanks and regards,
|

That's the point you can't do this. And why would you want to? If you have a textbox in your application and you need to pass the value from the textbox to an external application, then why do you need to try reassigning the input stream? Sounds more like you need to refactor the external application.

Hello.
We got a newbie question on XML tags for documentation (only partly referring to C#):
The text needs to use the data type of a function (or a function parameter). The documentation text goes the same for all programming languages though you have different data type namings in C#, VB.NET, C++ ... As an example, in C# and C++ you have float data type but VB names it Single.
A code example (VB here):
''' <summary>The function <cref name="myFunction"/> has the data type Single/float.</summary>
Public Function myFunction As Single()
Return myFunction(Me.Count)
EndFunction
Can we refer to the data type naming as we do to the function name? Could be a tag like <creftype name="myFunction"/>
We use VS2008 (and Sandcastle for html help).
Thanks for hints

float is an alias for System.Single. So you can write,
public float MyFunction()
{
}
