I expect they assume developer will write delete file code like this

public void DeleteFile(string filePath)
{
if(File.Exists(filePath))
File.Delete(filePath);
else
MessageBox.Show("File not exists, deleting file not performed");
//or throw an error message in their face
}

Some exceptions too
Exception Condition
IOException The specified file is in use.
ArgumentNullException path is null.
DirectoryNotFoundException The specified path is invalid, (for example, it is on an unmapped drive).
NotSupportedException path is in an invalid format.
UnauthorizedAccessException The caller does not have the required permission.-or- path is a directory.-or- path specified a read-only file.
ArgumentException path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.
PathTooLongException The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters.

Yes, it doesn't throw any exception if file not exists and they documented it.
Deletes the specified file. An exception is not thrown if the specified file does not exist.

public static void Delete(string path)
{
    if (path == null)
    {
        throw new ArgumentNullException("path");
    }
    string fullPathInternal = Path.GetFullPathInternal(path);
    new FileIOPermission(FileIOPermissionAccess.Write, new string[] { fullPathInternal }, false, false).Demand();
    if (Environment.IsWin9X() && Directory.InternalExists(fullPathInternal))
    {
        throw new UnauthorizedAccessException(string.Format(CultureInfo.CurrentCulture, Environment.GetResourceString("UnauthorizedAccess_IODenied_Path"), new object[] { path }));
    }
    if (!Win32Native.DeleteFile(fullPathInternal))
    {
        int errorCode = Marshal.GetLastWin32Error();
        if (errorCode != 2)
        {
            __Error.WinIOError(errorCode, fullPathInternal);
        }
    }
}

As you see it just checks if path is null or not and the permission.

First they should change project properties to use unsafe code from Project Properties window.

The similarity is existing.
And I don't know your level in C++, say you're advanced C++ programmer, so in 3 months you'll professionate C# and depends on the C# projects you are gonna develop.

It depends, excuse me, it's not a question. your question should be can I learn C# but the long time can't be determined.
Let me know when this question will be solved? when I say after 3 months :)
So, the answer is 3 months.

Yes, Danny, I begun to note that, the next coming days you'll find him asking a lot then no single thread to be marked as solved and even no replies.

What's the edition you are using + did you install server tools or client tools?

Evening, Danny :)
I didn't see your reply.

First please use Code tags.
Second, make class to handle this

class MyWord //may implement some interfaces
{
string word;
public string Word { get; set;}

int rank;
public int Rank { get; set;} 
}

Then when some search meets increase the rank.

Because you didn't take my code and just replace field1 with c, isn't it??
Surround second if with { }
Take my code copy and paste please.

private void FieldStore()
{
foreach (Control c in panel1.Controls)
{
if (c is TextBox)
if (c.Name == "field1")
{
c.Text = Area.Room1;
MessageBox.Show("This is Field1");
}
}
}

It works with me, do you work on Vista? if yes you run VS\your application as administrator.

What's this line field1.Text = Area.Room1; ??
Modify it to

private void FieldStore()
           {
               foreach (Control c in panel1.Controls)
               {

                   if (c is TextBox)
                       if (c.Name == "field1")
{
                           c.Text = Area.Room1;
                           MessageBox.Show("This is Field1");
}
               }
            
           }

You end users\stakeholders\clients must have SQLExpress formerly called MSDE (Microsoft SQL Server Desktop Engine). So you don't need to install SQL Server (Server tools).
Then how to attach the database there are a lot of ways to do it programtically may be through installation, may be standalone application do that work.

You can search how to add handlers to created controls at runtime using VB.NET then your problem is done.
http://www.thescarms.com/dotnet/EventHandler.aspx

http://www.google.com.eg/search?rlz=1C1CHMB_enEG312EG313&sourceid=chrome&ie=UTF-8&q=add+handler+to+controls+vb.net

Please attach the project or show us the whole code which creating\searching the TextBox. and don't forget to surround it inside code tag.

You're welcome, just made sure it meets your need.

That's what you needed?? or it popup unneeded string?

String html = richTextBox1.Text;
            List<string> matches = new List<string>();
            Regex r = new Regex("href\\s*=\\s*(?:\"(?<1>[^\"]*)\"|(?<1>\\S+))", RegexOptions.IgnoreCase | RegexOptions.Compiled);
            Match m;// = r.Match(
            for (m = r.Match(html); m.Success; m = m.NextMatch())
            {
                matches.Add(m.Value);
                MessageBox.Show(m.Value);
                //new modified code
                //newGroups.Add(m.Groups[index]); //not 1 as you say
            }

Can you please give me the link? to know what's this about.

No.

Excuse me Danny, Lighthead (Actually I don't know your real name).
Mansi please tell us your problem compilation error or fatal error in which line, etc.... it make that easier for us to help.

Sure it won't work as index not defined but what I need to say is you everytime add the same Group instance which in the index 1 of the array of Group.

String html = getSource();
List<Group> newGroups = new List<Group>();
r = new Regex("class=lnk href\\s*=\\s*(?:\"(?<1>[^\"]*)\"|(?<1>\\S+))", RegexOptions.IgnoreCase | RegexOptions.Compiled);
for (m = r.Match(html); m.Success; m = m.NextMatch())
{ 
      MessageBox.Show("Link" + m.Groups[1].Value); 
//new modified code
newGroups.Add(m.Groups[index]); //not 1 as you say
}

Read my comments in the code I may got you wrong.

May you have fun every minute you live, and I wish to see your post celebrating the 100th anniversary :)

My mistake, modify it to
== instead of =

foreach(Control c in Panel1.Controls)
{
if(c is TextBox)
if(c.Name == "field1") //or any property c.Text == "" or c.....
MessageBox.Show(string.Format("TextBox Name: {0} , TextBox Text {1}",c.Name, c.Text));
}

If you know anything about it. Its Text or its Name you can add a condition

foreach(Control c in Panel1.Controls)
{
if(c is TextBox)
if(c.Name = "field1") //or any property c.Text = "" or c.....
MessageBox.Show(string.Format("TextBox Name: {0} , TextBox Text {1}",c.Name, c.Text));
}

Here's a post I wrote but it's by C# you can see the idea and convert it to VB.NET http://fcihelwan.wordpress.com/2008/05/16/how-to-make-your-controls-moveable/

You're welcome my friend, Danny
I Hope it solves their problem.

foreach(Control c in Panel1.Controls)
{
if(c is TextBox)
MessageBox.Show(string.Format("TextBox Name: {0} , TextBox Text {1}",c.Name, c.Text));
}

No, Serkan it also used as they said in desktop application SQL Server Compact 3.5 is a free, easy-to-use embedded database engine that lets developers build robust Windows Desktop and mobile applications that run on all Windows platforms including Windows XP, Vista, Pocket PC, and Smartphone. read more

You're both right everyone has another piece of information.

@Lighthead
You're welcome.
Nothing called stupid, you're trying to help and you should be thanked.
Nice to have you around and trying to help others.

@Scott

In this class file i created an instance of "Card" structure successfully as shown in above code. But i cannot access the properties of structure like this(as shown bleow):

i created an instance of "Card" structure successfully as shown in above code
I bet there's no problem, I believe they have problem in something else.

Ema005 who said it's private the default is internal and it's!, and they can use it in the same assembly.
I take the code and run it, no problem.

You've something wrong it should work right.

What the at runtime created controls? TextBoxes or Buttons ?
If TextBoxes
You can add reference to recent created textbox name and perform the calculation
I.e: We created textbox its name textbox15

string recentTextBoxName = GetRecentCreatedTextBox();
string GetRecentCreatedTextBox()
{
///creating textbox at runtime
///return its name
}
void PerformCalcualtion(string textBoxName)
{
foreach(Control c in Controls)
if(c is TextBox)
if(c.Name == textBoxName)
//perform calculation on c
}

If buttons
when you create button assign a handler to it

///initialize controls properties
button1.Click+=new EventHandler(button_Click);
button2.Click+=new EventHandler(button_Click);
button3.Click+=new EventHandler(button_Click);

void button_Click(object sender, EventArgs)
{
///some code
}

Create project from type VC++ and add its output assembly to C# project. I'm using VSTS 2008 which permits that, I don't know what version you're talking about.

I don't know where your problem actually in, but if you succeed to develop application in C# to take backup then you may turn into MySQL forum to ask about anything related to MySQL

He can also add in splitters what you need
It may be also array of string to have something like that ("\r\n") if you read from text files.

It's up to you, all end with the skills you can grow them up, if you're smart you'll do anything by anything.
But I should say something C# is full of features and I like it, the most programming language has community based solution. That's my opinion personal opinion.

I think they need to have Label and scroll its contents.
Please answer us.

Need to export MySQL database to ??
I recommend you to use SQL Server Integration Services
P.S: Destination ought not to be MS SQL Server.

To get word by word then search on specific word

int GetWordIndex(string word)
{
char[] splitters = new char[]{' '};
string[] wordsArr = RichTextBox1.Text.Split(splitters, StringSplitOptions.RemoveEmptyEntries);
for(int i=0; i< wordsArr.Length; i++)
if(string.Equals(wordsArr[i], word, StringComparison.InvariantCultureIgnoreCase))
return i;
return -1; //indicates there is no match
}

Go ahead :)

Use Setup wizard project to create an package for installation.

You'll need to play with DataBound Event Handler, read this post http://www.csharphelp.com/archives/archive151.html and try to apply the concept on your case

Please use code tag :)

static void Main(string[] args)
{
//code to call the method Getnames and print the value of name here..
Demo d = new Demo();
List<MyTest> m = new List<MyTest>();
d.GetNames<MyTest>(m);            
}
