I want to replace Dash with a period only once in a string like

ABC-XYZ =ABC.XYZ

ABCXYZ =ABCXYZ (No Replace)

ABC-X-Y-Z =ABC.X-Y-Z

A-BC-XYZ =A.BC-XYZ

ABCXYZ- =ABCXYZ.

I found where the first dash is match using of IndexOF property of string.
And RegEx.Replace replace all the found characters I want to replace only first occurrence.
But how I can replace only once...?

Regards

If you want to shape your dreams into reality, please wake-up...

write your own function, use loop, if character found then replace and then break or return.

string str = "ABC-X-Y-Z";
int index = str.IndexOf("-");
str = String.Format("{0}{1}{2}", str.Substring(0, index), ".", str.Substring(index + 1, str.Length - index - 1));

Hope it helps.

I will use Google before asking dumb questions

Thanks for your reply.

But it will give error in case of

string str = "";

Because this input is depend upon the end user So I can-not say the input data in Correct format.

Or if dash is not found then it will also give the error.

I make new code please let me know this is Ok or not...?

Hi,
here before checking anything you have to check that
if(str.Length > 0)
{
if(str.Contains("-"))
{
// here write everything.. will not give any error.
}

}

Hi.
I hope this work for you.
Write this in your some click events.

string xNew="";
int j = 1;
for (int i = 0; i < TextBox1.Text.Length; i++)
{
string x = TextBox1.Text.Substring(i, 1);
if (x == "-")
{
if (j == 1)
{
xNew = xNew + ".";
j++;
}
else
{
xNew = xNew + x;
}
}
else {
xNew = xNew + x;
}
}
Label1.Text = xNew;
Small Logic.
Thank you.

Hi.
I hope this will help you out..
Write somewhere in button event and test it....
string xNew="";

for (int i = 0; i < TextBox1.Text.Length; i++)
{
string x = TextBox1.Text.Substring(i, 1);
if (x == "-")

j++;
}
else

Label1.Text = xNew;
Thanks for watching it....

- before you ask a question here, search CodeProject, then Google
- the quality and detail of your question reflects on the effectiveness of the help you are likely to get
- use PRE tags to preserve formatting when showing multi-line code snippets

Yet another way:

C#

if ( args.Length > 2 )
{
    int index = args [ 0 ].IndexOf ( args [ 1 ] ) ;
 
    if ( index >= 0 )
    {
        args [ 0 ] = (new System.Text.StringBuilder ( args [ 0 ] )).Replace ( args [ 1 ] , args [ 2 ] , index , args [ 1 ].Length ).ToString() ;
    }
 
    System.Console.WriteLine ( args [ 0 ] ) ;
}

How about this? Thanks for the opportunity.

C#

public static string
Replace
(
    string Subject
,
    string Old
,
    string New
,
    ushort MaxReplacements
)
{
    System.Text.StringBuilder result = new System.Text.StringBuilder ( Subject.Length ) ;
    string[] parts = Subject.Split
    (
        new string[] { Old }
    ,
        (int) MaxReplacements+1
    ,
        System.StringSplitOptions.None
    ) ;

    result.Append ( parts [ 0 ] ) ;

    for ( int runner = 1 ; runner < parts.Length ; runner++ )
    {
        result.Append ( New ) ;
        result.Append ( parts [ runner ] ) ;
    }

    return ( result.ToString() ) ;
}

Hi,
I have a textbox which get a number(Amount of money) from user.
i want to show the enterd number like this : 0,000,000(1,123,145)(automatically add (,) after 3digits enterd)
when i use masking it doesn't work the way i want it ,
can any one help me on this?

Winform or webform?

In winform, you can use MaskedEdit standard control.. In web form, you have to find the custom control (e.g. http://www.codeproject.com/useritems/MaskingText_for_ASPNET.asp)

in winform
I used defult masks but they didn't work porperly
what I've tried to do is to automatically add a (,) after 3digits is enterd
thanks

If your text is static, you can use #,###,###(#,###,###) in Standard masked edit. if you want to enter the text as much as you want then you should consider using thoundsand seperator function in keypress event of textbox..

hi all,

I have a panel which contains a picturebox and two textboxes. in one of the textbox, some large content is to be displayed. this content is dynamic and i want the textbox to wrap the text accordingly.

i set the textbox multiline property to true and also set wordwrap=true. inaddition i set the acceptsreturn=true.

but still the text is not wrapped.

how can i achieve this?

Thanks in advance. Smile | :)

Try to enter the real paragraph.. sometimes, people used to entry "aaaaaaaaaaaaaaaaa" or something with space . this is wrong. So, try to enter the real paragraph (maybe, copy from news or somewhere) and see whether it works or not..

hi,

i am actually trying with a real paragraph which is obtained dynamically. when i put a dummy paragraph and tested its working fine.

but when i put the dynamic content which contains more paragraphs, the text is not wrapped properly.

Any ideas?

and thanks for the response.

Regards

Anuradha

What about trying the dynamic content as a static content? For example: You store the text in database, right? so, copy this text and pasted in HTML. check whether it is wrapped properly or not.

or you can show us the content that you stored in database. then, we can test in our side and will let you know the result..

hi,

Thanks so much for your help. i got it working now. i had added the picturebox and two textboxes during design time. now i added them at runtime and set the all properties again.

now its working fine although i have a vertical scrollbar for the textbox. but without that the panel becomes so big so its better i have the vertical scrollbar.

thanks once again for your help.
