First off, consider if your software is worth somebody spending the time to decompile your code just to be able to use your application and then publishing a license generator in the web. (Take into account that the average user will not have the skill to do this)
If the answer is yes, then I wouldnt waste too much time...it'll get cracked anyways...just do a search in google for 'Keygen' and any software developer will cry himself to death. :p and I'm sure most of those apps have spend hours and money way beyond what ur will to try and stop that from happening.

Hi,
I need print a data from an big array in severals columns.
I can not find in C# a way to to "write " an array similar to
Fortran statement like:
WRITE (*;100) (a(i) , i =1,20)
100 FORMAT (1X, 'a= '; 20F10.2)
Thanks
Ted

I need write some values from an array in columns like below
for (int np=1; np < NP1 ;np++)
{
writer1.WriteLine ("{0,8},{1,8},{2,8},{3,8},{4,8},{5,8},{6,8},{7,8},
PARAM[1],PARAM[2],PARAM[3],PARAM[4],etc...
}
The problem is that the number of columns is calculated by the code
/it can varied/ . Second only a part of array should will be printed.
Regards
Ted

Can't you just nest another loop? Like:
int cols=3;
int testCount=PARAMS.length;
for (int rowIndex=0;rowIndex < Math.Ceiling (Convert.ToDouble (testCount) / Convert.ToDouble (cols));rowIndex++)
{
for (int colIndex=0;colIndex < cols;colIndex++)
{
if (rowIndex * cols +colIndex < testCount)
{
writer1.Write(PARAMS[rowIndex * cols +colIndex].ToString () + " ");
}
}
writer1.WriteLine();
}
That should write it one row at a time:
0 1 2
3 4 5
6 etc.
Hope this helps
Bill

My problem is now much more trivial:
how I can get my output as a row?, instead for column from example as below:
int []PARAM = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17};
int zmax =11;
for (int z = 0; z < zmax+1 ; z++)
writer1.WriteLine(PARAM[z].ToString()+ " ");
=== output
1
2
3
4
5
6
7
8
9
10
11
12

Oh! That is easier. 
I do not know what writer1 is, since none of your previous posts contain a declaration...but in many cases there is a .Write() method as well as a .WriteLine. Is so you can do:
for (int i=0;i < PARAMS.Length; i++)
writer1.Write(PARAMS[i].ToString() + " ");
writer1.WriteLine()
If you have no Write, just build the string up before you print it.
System.Text.StringBuilder sb = new System.Text.StringBuilder();
for (int i=0;i < PARAMS.Length; i++){
SB.Append(PARAMS[i].ToString() );
SB.Append(" ");
}
writer1.WriteLine(SB.ToString())

I've got a small utility that occasionaly locks up in itself if a client does not respond, so I have added a time out clause by creating a side thread for it to run on, and killing the thread when the timeout condition is reached OR the thread completes.
However, creating an entirely new thread to run this on just seems daft, so i'd like to do it on a ThreadPool. Is there any way to kill a thread pulled from a thread pool after a certain amount of time?
Cheers
Cata

I solved a similar problem another way. I created a class to hold each thread's info. i.e. ThreadID,StartDateTime,InUse,Finished etc...
Then when a new thread is required I add an instance of this class to an array which is monitored from a single worker thread. In the worker thread I interate through the array of threads and kill the ones that have the Finished flag set or that have exceeded my timout based on StartDateTime, and InUse flags. That way you can handle the termination of each thread based on what type of operation it is.
Don't know if this is applicable to your solution or not, but it worked great for me.
|

|

My solution is very similar, but i use the ThreadState of the thread I create. THe thread is only active for at most 1200ms and on the median about 15ms, before it is terminated. Therefore, creating and disposing new threads is a waste.
I was looking for a way to use the thread pool as it would be a more appropriate solution.

Hello, please can anyone help. I need the article and source code for the C# Sorted ListView by Carlos H. Perez, as it is not at the following link anymore. I use a listview which continuously updates two of the subitems, which is causing bad flickering. I need to know how to update subitems on a listview, without redrawing the whole row.

If anyone has the sourcecode please can they send it me.

hi
i want to check what key on keyboard is presed.
how kan i get the key pressed char code?
thanks
|
|

Create an event handler for the KeyDown, KeyPress or KeyDown event and evaluate the specific EventArgs object, that will be passed to the event handler.
www.troschuetz.de
|
|
|
|
|
If you are using a control (i.e. TextBox) you can use the KeyDown Event as follows:
private void ValueEdit_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
try
{
if(e.KeyCode == Keys.Enter)
CloseEditBox(true);
else if(e.KeyCode==Keys.Escape)
CloseEditBox(false);
}
catch(Exception Err)
{
throw new Exception("KeyDown: "+Err.Message);
}
}
if you want to trap the keyboard events for an entire application, you can override the WndProc method and look for the WM_KEYDOWN message

I am creating an instance of class at runtime from assembly through reflection.I then Serialize the class(including the delegates) and send it to remote machine from where I deserialize the received bytes.I can get an Exception i.e. its not deserialized in short!
However when I perform this whole mechanism without including Delegates... it works and the result is exactly what i want.
Can somebody help me on this ?
Thanks in Advance!

hey guys, i need to check a stirng if it contain the "ESC" character i searched for the representation of this char which was '\e' but when i write this char in the C# code it doesn't recognize it, does anyone knows how to do it?
|
|
|
|
|
What do you mean "when i write this char in the C# code"? How do you "write" it? The .NET Framework General Reference states that \e is the escape sequence for the ESC character, but it really matters what your "string" contains, how it's encoded, and how you're searching for the string. How are you searching the string? How is it encoded?

i ment simply writing a string whith this character as the following:
string strTest = "This is a Test\e string" ;
the '\e' character should represent an ESC but the compiler doesn't recognize this escape character, any way i found another way which is represnting the ESC as the follwoing:
string strTest = "This is a Test\u001B string" ;
the '\u001B' match the ESC char.
actully u can write the following:
char chTest = '\u001B' ;
which is totally legal.

Hello,
I am using the generic TreeView Control from .Net 2002.
I want to have the root nodes of the control to have a bold font and I thought this could be easily done by setting the NodeFont attribute of the node.
However, when I do this the font is indeed bold but it seems that the control does not resize the text box the node text is drawn in and the text gets clipped (I assume becase the new bold font is wider than the previously assigned text which isn't bold by default).
Does anybody know what I can do to fix this.
Sample of code below:
TreeView treeView = new TreeView();
...
TreeNode tn = new TreeNode("Test");
tn.NodeFont = new Font(treeView.Font, FontStyle.Bold);
...
Thank you in advance,
Eric

|
|
|
|
Simply add this line to ur code
TreeView treeView=new TreeView();
..
TreeNode tn = new TreeNode("Test");
System.Drawing.Font newFont=new System.Drawing.Font(treeView.Font, FontStyle);
tn.NodeFont = newFont;
treeView.Font = newFont;
...
//I hope u wud have understand the reason :P
Take Care
