Don't worry about it. It isn't anything personal. It is just that many folks from India have a propensity to ask questions first rather than go and read the documentation first. Think of it as a culture clash. In the west the preferred (polite) route is to do some research first and if that fails to ask questions and be prepared to show that you've done the research.

West, shmest! In the real world you're expected to use your initiative and to ask sensible questions when you've done a reasonable amount of research for yourself.

Well, it seems to me that it is mostly folks from the east (and in particular India) that make the mistake of not attempting to do research.

Its not like that..
I came here only after I had googled the question..
But I came here to have an indepth analysis of my query..
Anyways, I dont think its good to comment on other folks and countries like that..
We all are here to help and get help..
Even if somebody dosent make research, he should be told to do so and not comment on any particular region or nation..
That shows how you respect(or dont) other people..

Got u Colin..
I took it personally until I saw your post..
But there should be polite ways to answer too..
People shouldnt be commenting on other countries and the attitudes of people, I guess that is regarded RUDE everywhere..
I admit I made research but not that much, will do in future..

Well, good luck then. Obviously you'll be wanting to read up on this via Google. We aren't going to write your software for you. BTW - choose a better title; we know it's C#.
|
|
|
|
|
1. Please use a descriptive subject line. Given this is the C# forum, every post could carry the subject of C#.
2. We don't do homework here. On the other hand, if you are stuck at a particular place, we'd be happy to help.
3. Please read the guidelines above.
Cheers,
Vikram.

It's not that nobody wants to help you, but you made a wrong post.
- Correct forum --> this was good
- Correct language --> Wrong, please create full sentences and mind spelling errors. You're american, people would think you can write in your own language.
- Give a good, (short), clear description in the subject.
- Tell us what you did yourself to find a solution to the problem
- it proves your not lazy and awaiting an answer while you're watching the television.
- it prevents people from going down a line you already searched.
- It doesn't matter if it's homework, real work or just for fun, just show you did some research yourself
- people will guide you and give a direction, they will not do the task for you.
- some people take the time to actually do research for you, take time to thank them for their effort.
hope this helps.

Guys,
Check out the following
private void btn_disable_Click(object sender, EventArgs e) {
IntPtr handle = FindWindow(null, "windowtitle");
Form.FromHandle(handle);
IntPtr chandle = GetDlgItem(handle, Convert.ToInt32(txtbox_controlid.Text));
Control.FromHandle(chandle);
string text = "";
GetWindowText(handle, text, 10);
MessageBox.Show(text);
}
[DllImport(@"user32.dll", EntryPoint="GetDlgItem")]
public static extern IntPtr GetDlgItem(IntPtr DialogHandle, int ControlId);
[DllImport(@"user32.dll", EntryPoint="FindWindow")]
public static extern IntPtr FindWindow(string ClassName, string DialogTitle);
[DllImport(@"user32.dll", EntryPoint="GetWindowText")]
public static extern int GetWindowText(IntPtr Hwnd, string text, int length);
both handle as chandle give back an IntPtr different from zero. Yet my MessageBox will stay empty.
If I try to create a Control (Control.FromHandle(chandle);) I get back a null value.
I did find an article that uses SendMessage to manipulate controls, but I was wondering if I couldn't plug in into the control via a reference or something. (like TextBox.FromHandle(found_handle)). [EDIT]Goal is to get hold of the properties and methods of the control like backColor, ForeColor, GetWindowtext, SetWindowText, Enable, Visible, ...[/EDIT]
Am I on the wrong path here or did I just miss a detail?
thanks !!

Control.FromHandle(HWND) should return a reference to a Control. For the string to function properly, pass in a StringBuilder.
private void Test() {
IntPtr handle = FindWindow(null, "Form1");
Control c = Control.FromHandle(handle);
StringBuilder text = new StringBuilder();
int x = GetWindowText(handle, text, 10);
MessageBox.Show(x.ToString() + text.ToString() + c.Text);
}
[DllImport(@"user32.dll", EntryPoint = "GetDlgItem")]
public static extern IntPtr GetDlgItem(IntPtr DialogHandle, int ControlId);
[DllImport(@"user32.dll", EntryPoint = "FindWindow")]
public static extern IntPtr FindWindow(string ClassName, string DialogTitle);
[DllImport(@"user32.dll", EntryPoint = "GetWindowText")]
public static extern int GetWindowText(IntPtr Hwnd, StringBuilder text, int length);

Hey,
Thanks for the reply. The StringBuilder option is indeed working, but getting an instance of a Control doesn't seem to work. (it stays null) It could be because the other application is a VC++ application and not .Net ??
thanks.

You have to make sure that you are looking for the correct window title. The search is done by that parameter, case sensitive. In my example, I left the title to default "Form1", change that to the title of the VC++ window.

lol, thanks, that is working, but if I take that handle and try to create a Form or Control with the FromHandle method, it will still result in null, although GetWindowText is working.
IntPtr handle = FindWindow(null, "windowtitle");
Form f = Form.FromHandle(handle);
Control c = Control.FromHandle(handle);
string text = "";
GetWindowText(handle, text, 10);
MessageBox.Show(text);
So in this case both f and c are null, but the MessageBox will show my dialogtitle.
My theory is that the code can't convert a Dialog or a Control from a VC++ form/control to a .Net form/control, but I'm not sure about that. 
thanks !
(and sorry to be so difficult )

Hello everybody,
in a DBF Database the strings are written in a given way.
If i read out the strings in C++ i get for the €-Char the Integer-Value -128
In C# i read out the string of the DBase-Table via the ODBC-Connection.
There the Integer-Value is 199 (and does not belong to the €-Char)...
if i convert the character set with Encoding.GetEncoding(858)
i get the right €-Char but has also a integer-value of 8364
How can i convert the values to obtain the -128?
Big thanks in advance !!
|

The Euro symbol wasn't part of the original ASCII set, but this[^] page says after installing a patch ASCII 128 becomes the Euro sign.
8364, on the other hand, is the Unicode value for the Euro sign and is safer to use.
Cheers,
Vikram.

Hi master,
I got this error message when initialize matrix with so large number MxN
An unhandled exception of type 'System.StackOverflowException' occurred in [project name].exe
I dont know how to pass this error, anyone can help me please? This is my code:
<br />
class image<br />
{<br />
<br />
<br />
public void zoning()<br />
{<br />
int Max = 0;<br />
for (int i = 1; i < M - 1; i++)<br />
for (int j = 1; j < N - 1; j++)<br />
if (Img_In_Process[i, j] == -1)<br />
{<br />
Max++;<br />
Point_Zone(i, j);<br />
}<br />
}<br />
<br />
private void Point_Zone(int i, int j)<br />
{<br />
Img_In_Process[i, j] = Max;<br />
if ((i - 1 >= 0) && (Img_In_Process[i - 1, j] == -1)) Point_Zone(i - 1, j);<br />
if ((j - 1 >= 0) && (Img_In_Process[i, j - 1] == -1)) Point_Zone(i, j - 1);<br />
if ((i + 1 < M) && (Img_In_Process[i + 1, j] == -1)) Point_Zone(i + 1, j);<br />
if ((j + 1 < N) && (Img_In_Process[i, j + 1] == -1)) Point_Zone(i, j + 1);<br />
}<br />
}

You are recursively calling Point_Zone too many times and running out of stack space.
Cheers,
Vikram.

As the other poster said, you are going too deep recursively.
Now you have 2 options:
a. Rewrite the algorithm so it does not need recursion, in other words iteratively.
b. Use editbin to increase the stack space if this is indeed a borderline case and an attempt at (a) failed.

Thanks for your reply, leppie.
I can not change my algorithm so I must increase stack space,
But I dont know how to increase the stack space, please help me!!

He already did, see his reply.

I would look into ways of changing the algorithm first though.

Hi Yusuf,
Yes, I read his reply already, but I dont know exactly how to use EDITBIN? Where is it??? Can you explain where to find that? Is it command or function of MS VS C#?
Best regards.

Hello.. im alittle new when it comes to handling threads and all the crap.. and i would really appreciate if someone would be able to give me some guidance tips..
i have tried to build a small search program who runs up of my entire hard drives (for now it was limited to windows directory)and to give me the strings that matches to the search box..
well it works perfectly.. though it takes a while to search because i dont know how to use multi threading..
i have tried reading articles but i always get stuck at some point... for now ive managed to create one single thread and when im trying to send another one .. they dont synchronize it just multiply the result by 2...can please someone direct me to the answer and help me abit.. wide explanations will be awesome
here's the code
the main procedure:
<br />
namespace SearchFile<br />
{<br />
public struct directors<br />
{<br />
public DirectoryInfo Dir;<br />
public bool processed;<br />
}<br />
public partial class Form1 : Form<br />
{<br />
<br />
directors direct;<br />
public string location = "";<br />
public delegate void invokegetdirecotrs(directors dr);<br />
public Form1()<br />
{<br />
InitializeComponent();<br />
}<br />
public void getDirectors(directors dr)<br />
{<br />
<br />
if (this.InvokeRequired)<br />
{<br />
invokegetdirecotrs inv = new invokegetdirecotrs(this.getDirectors);<br />
this.Invoke(inv, new object[] { dr });<br />
}<br />
<br />
else if( dr.processed == false)<br />
{<br />
dr.processed = true;<br />
int i = 0;<br />
Array Sub_Dir;<br />
FileInfo[] fi = dr.Dir.GetFiles();<br />
string comparest;<br />
Sub_Dir = dr.Dir.GetDirectories();<br />
if (Sub_Dir.Length > 0)<br />
{<br />
for (i = 0; i < fi.Length; i++)<br />
{<br />
comparest = fi[i].Name.ToString();<br />
for (int j = 0; j < comparest.Length - location.Length + 1; j++)<br />
{<br />
if (location == comparest.Substring(j, location.Length))<br />
{<br />
j = comparest.Length;<br />
listView1.Items.Add(fi[i].FullName.ToString());<br />
}<br />
}<br />
<br />
}<br />
foreach (DirectoryInfo d in Sub_Dir)<br />
{<br />
DirectoryInfo di = new DirectoryInfo(d.FullName.ToString());<br />
direct.Dir = di;<br />
getDirectors(direct);<br />
}<br />
<br />
}<br />
else<br />
{<br />
fi = dr.Dir.GetFiles();<br />
for (i = 0; i < fi.Length; i++)<br />
{<br />
comparest = fi[i].Name.ToString();<br />
for (int j = 0; j < comparest.Length - location.Length + 1; j++)<br />
{<br />
if (location == comparest.Substring(j, location.Length))<br />
{<br />
listView1.Items.Add(fi[i].FullName.ToString());<br />
j = comparest.Length;<br />
}<br />
}<br />
<br />
}<br />
<br />
}<br />
}<br />
}<br />
and the button click
<br />
private void button1_Click(object sender, EventArgs e)<br />
{<br />
<br />
listView1.Items.Clear();<br />
location = textBox1.Text;<br />
if (location != "")<br />
{<br />
DirectoryInfo dir = new DirectoryInfo(@"c:\divx");<br />
directors dr;<br />
dr.Dir = dir;<br />
dr.processed = false;<br />
ThreadStart starter = delegate<br />
{<br />
getDirectors(dr);<br />
};<br />
new Thread(starter).Start();<br />
<br />
ThreadStart starter1 = delegate<br />
{<br />
getDirectors(dr);<br />
};<br />
new Thread(starter1).Start();<br />
<br />
<br />
}<br />
}<br />
