Looks as if you will need a full path to cat.jpg

public string ReverseSentence(string sentence)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
string[] words = sentence.Split();
System.Array.Reverse(words);
for (int i = 0; i < words.Length; i++)
{
sb.Append(i == words.Length - 1 ? words[i] : words[i] + " ");
}
return sb.ToString();
}

Personal preference is not to use String Builder.

You are using port 587 but no network credentials(System.Net.NetworkCredential).
SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
client.Credentials = new System.Net.NetworkCredentail("$yourgmailaccount", "$yourgmailpassword");

Directions is a string but in your case statement you treat it as an int
switch (Direction)
{
case "Forward":
//do something here
break;
case "Back":
//do something here
break;
}

If you're expecting an int then you will need to convert the string to int or change Directions from string Directions to int Directions. There's many possibilities to what Directions are a reference to. What value is passed to Directions?

disregard the later half of my last comment. Are you using a WebBrowser Control or are you using asp.net?

Did you Find the link useful?

see my reason above

CreateParams can only be called once but setting the opacity to 0 someone else could easily say Form1 form = new Form1(); form.Opacity = 100; form.ShowDialog(); now form is visible, where they can't make another instance of CreatParams to make Form Visible.

thanks but no thanks got it fixed

Great Example but, I would set the Cancel button to DialogResult.Cancel, but i would call the Login Button to DialogResult.Cancel if UserName and Password Didnt Match and to DialogReust.OK if They Did. Just a thought :)

Well if you think so where is the Alternative????

updated my vote to 4 works just great but stil perfer my method as i like to use enum values and switches but good job on the alternate :)

It's Javascript

Reason for my vote of 1 Yes it very well could be I just personally am a fan of switches and enum's plus it makes the code look cleaner. Also why would you use OpenSubKey if you don't even know if the key Exist? If you are going To do that then you need to Check if the Key Exist First.
bool exists = true;
using (RegistryKey key = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\TestApp\1.0"))
{
if (key == null) exists = false;
}
if(exists)
{
// now set the value
}
else
{
// use CreateSubKey
}
Using CreateSubKey will Create if it doesn't exist and if it does exist will set the sub key so it cuts out needing to check if the key exist :) Plus I just checked you method running regedit from command line and yours doesnt change value.

Sorry was slow on the reply lol

I have given it thought yes, able to accomplish as of this moment no, I will continue to try and find the answers but since your unable to give me an example would you mind a revote, Thank You :)

I haven't come across anyone yet who can...Can you? If So Please Do Leave An Alternative...If not Please reconsider changing you mind on the vote :)

Good one i have used before works well and less confusing for user :)

I Agree with the Griff here much easier and less confusing for the end-user and as well if you will take a look at some of the downloads you install from Microsoft they use the same method(or at least the X box is disabled) which this is a much better way to do for the end user because they know that the button is to be red and takes away much confusion.

To use just do this

TabPage MySelectedTab = ActiveTab;
if (MySelectedTab != null)
{
// do what you need with the Selected TabPage Here
}

Look easy way

public partial class Form2 : Form
{
private Form _ParentForm;

public Form2(Form form)
{
InitializeComponent();
this._ParentForm = form;
}

private void button1_Click(object sender, EventArgs e)
{
this._ParentForm.Close();
}
}

Now to use the method Form2 form = new Form2(this);
form.Show();

yes but easier for someone else to change yours

thanks here is a numericTextBox control I belive that i got from MSDN
public class NumericTextBox : TextBox
{
bool allowSpace = false;

// Restricts the entry of characters to digits (including hex), the negative sign,
// the decimal point, and editing keystrokes (backspace).
protected override void OnKeyPress(KeyPressEventArgs e)
{
base.OnKeyPress(e);

NumberFormatInfo numberFormatInfo = System.Globalization.CultureInfo.CurrentCulture.NumberFormat;
string decimalSeparator = numberFormatInfo.NumberDecimalSeparator;
string groupSeparator = numberFormatInfo.NumberGroupSeparator;
string negativeSign = numberFormatInfo.NegativeSign;

string keyInput = e.KeyChar.ToString();

if (Char.IsDigit(e.KeyChar))
{
// Digits are OK
}
else if (keyInput.Equals(decimalSeparator) || keyInput.Equals(groupSeparator) ||
keyInput.Equals(negativeSign))
{
// Decimal separator is OK
}
else if (e.KeyChar == '\b')
{
// Backspace key is OK
}
// else if ((ModifierKeys & (Keys.Control | Keys.Alt)) != 0)
// {
// // Let the edit control handle control and alt key combinations
// }
else if (this.allowSpace && e.KeyChar == ' ')
{

}
else
{
// Consume this invalid key and beep
e.Handled = true;
// MessageBeep();
}
}

public int IntValue
{
get
{
return Int32.Parse(this.Text);
}
}

public decimal DecimalValue
{
get
{
return Decimal.Parse(this.Text);
}
}

public bool AllowSpace
{
set
{
this.allowSpace = value;
}

get
{
return this.allowSpace;
}
}
}

you use OnKeyPress write a method then post an alternative, you google what you want dont pass your ignorance off on me

Your not very bright are you?

what is a new? ok create one address but what about the other? You still need both

You are correct Chris, sorry was in the middle of two different projects when posted this tip but still no excuse., the string.Format() method would easily suffice for formatting the rgb to hex. EdMan apoligies for the lack of explanation on the tip/trick, thought the title gave it away, sometimes we forget to remember that the tip/tricks that we supply are also read by newbies to the language and should be adaquately explained. String.Format is a very important tool you will want to read up on this topic. A simple example would be MessageBox.Show(String.Format("Your Name is {0}!!!", textBox1.Text)); if the text in textBox1 is EdMan the output would be.... Your Name Is EdMan!!!

The point was a way using Enum.Parse not a simple DockStyle thanks for the effort though this might be a good solution if not using Enum.Parse thanks for the post

please see 12 Apr '11 reply

report wrong? it returns the first 3 letters of the drive c:\, f:\, d:\, etc. etc. Not sure of the file system virtualization will have to look into that but as for privileges Environment.SystemDirectory.Remove(3) simply returns the top directory of the local user if i'm missing something please eloborate??

see my previous comment

Works just fine brain i've even checked myself although one line of code is incorrect
[DllImport("wininet.dll")]
private extern static bool InternetGetConnectedState( int out Description, int ReservedValue ) ;
Should be
[DllImport("wininet.dll")]
private extern static bool InternetGetConnectedState( out int Description, int ReservedValue ) ;

No the boolean can be either user or the person using code snippet, however the person using the snippet decides. you can hard code the boolean value to always return true or always false, return true if certain conditions are met such as the commandline arguments meet a certain criteria, or if say settings value or xml value are set to either true or false then it will allow or not allow second instance based on the supplied criteria. they are different in the sense that it will allow the value to be different based on the boolean value but they are the same as in the sense that they will both prevent a new instance from starting making it a single instance the boolean must be set to true.

A new instance of form will not run if value is set to true but will if value is set to false. this gives whoever uses the snippet to hardcode the true false value or if certain conditions are meet to run a new instance but it does not have a chance if the value is true

Reason for my vote of 5
nice alternative

Reason for my vote of 5
good example my 5

if your going to vote atleast leave a comment explaining the reason for you vote. It works and much smaller code than most

not great wit regex. if you could possibly post an example to study would be glad to learn and update

too monstrous? :Laugh it's a array, dumb ass it was placed as such for demonstration read from text file, resource, xml file, ini file, database...Would you really expect someone to keep that array in code? Honestly!! use your brains if you have any

if you want to allow characters that are in the UnappovedChar then just remove that char from string and continue as normal

It really doesn't make a differnce the Control.CheckForIllegalCrossThreadCalls is For debug purposes

it's the exact same code just reworded To include as class file same result's no difference

yea same problem i ran into thats why i posted above. What some Op's dont seem to realize is because it works on there computer. Unless there going to send each client a computer running the same os as they are RAVI that would become quite expensive try to make your code more robust. look outside your box and try to make work for all.

thanks for the feed back. I took a look at the link. It basically use the bluetooth support from a mobile to interact with the bluetooth to establish connection with other devices and so forth. Perhaps my Question was not clearly stated, Apoligies please allow me to elaborate. I am using Serial Ports but I use bluetooth from my mobile to create a connection with the computer. Once a connection is made I assign a Com Port3 to my mobile to allow my mobile to ask as the com port. In this manner it would be free to send sms messages. I have no trouble on this part as when i attempt to send the message my mobile ask for permission to interact with Chico-PC (my computer). When I hit OK then the app opens the com port to send the Message. The App shows no sign of the message not being send and I also have it set to show me errors from the com port as well as breakpoints inserted to catch any errors but the message is never delivered. I have searched Google and CP and have found a great deal of tutorials and documentation but still no luck. Again i appreciate the help and will keep you informed on any progress. If you see any documentation that you may feel could be beneficial please make we aware of it and thanks again.

Thanks hope it helps

Sorry, I've gotten to the point where the port opens..No errors are thrown..try to write AT command using a code that I found here on CP but never recieve text message. By the way my bluetooth from phone is connected to computer under Comport 3. thought maybe that was the reason, So I sent to my wife's phone but still no luck... Any suggestions?

Reason for my vote of 1
reason stated above

Reason for my vote of 1
reason for my vote of 1. I don't see anywhere that it prevents a new instance from starting.

why would you base the opacity on the timer1.Interval? thats to control how slow or fast the fade effect is to be.....Without having to recode every time. Plus Your code doesnt even Run Properly because it doesnt even fade in or out because it is invisible on Load. You might want to take a look at the code and work out the bugs.

john you are correct it's easier to add image for example so that users can easily see how it's done, First of all Secret_Garden a base64 image will show just as well and a base64 can be an embedded resource as well. All you have to do is put the Base64String into a text file and read as a string using the method above., Indivara what do you mean forgotten to encode the < and >?

My Post the original tip/trick does use Mutex and where does the run application call come in?

If you like and it works for you please rate me a 5

First It Does Work and Two I Think your missing Your If Statement
here is a better look at the code

bool bFailed = false;
bool condition1_fails, condition2_fails, condition3_fails;
// this is basically what the code is saying
/* if (!bFailed)
condition1_fails = condition2_fails = condition3_fails = false;
else
condition1_fails = condition2_fails = condition3_fails = true;*/

// so here you have the outcome with no errors when setting bFails to represent the true/false statements from above. With your code try to add a true false value you get the error The left-hand side of an assignment must be a variable, property or indexer.

// so try using this. Go ahead and give it a try... Change your bFailed value between true and false to test.
bool bFailed = false;
condition1_fails = condition2_fails = condition3_fails = bFailed;
if (bFailed) DoFailedCleanup();
else {
PerformActionOnAllSuccess();
DoNormalCleanup();
}

how about this
bool bFailed = false;
if (!bFailed) bFailed = condition1_fails = condition2_fails = condition3_fails;

if (bFailed) DoFailedCleanup();
else {
PerformActionOnAllSuccess();
DoNormalCleanup();
}

thanks

In a way of speaking anything that is done differently(even slightly), regardless of how effortless the change may seem is considered an alternative. I say this because Alternative only means a different way to do something but I can also see where you are coming from Sandeep and i also see no major improvement in the code but what i do see is less code which is also a plus. in some cases Less bulky code and less loops can result in faster and less painful application lags and response times.

Dont you mean System.Windows.Forms for OpenFileDialog?

You could also use Xml file to accomplish this

True that is another way to do the same thing. The reason that I built it the way that i have is so the code will be in a class file so that it can be included in a framework

How is that not clear? He wants to raise a click event on a button on completion of a timer tick!

too bad there is no 0
