 see code that I put in question will cath from site that I can put it in website and see video from that site... this code is stable for all video just below code is variable

data[W]=640 and this is width of video that will display in website now here I define textbox that users can enter this code and save it to database and in otherpage I will show this video...

in show.aspx page I define lable that bind it from database that will bind this code:

<div id="14921567137600375"><script type="text/JavaScript" src="https://www.aparat.com/embed/gRamq?data[rnddiv]=14921567137600375&data[w]=640"></script></div>

and will display video

now problem is this video will display in size that is in this code:

data[W]=640

I want change this size when users want insert it into database becuse I want show all video in fixed size that I define i.e

data[w]=300

so I want define code that when users typed code and want insert into database it will change

data[w]=640 to data[w]=300

and as I told data[w]=640 is variable maybe some users will select video with data[w]=290 or other thing

so I want it replace data[w]="with any number" with data[w]=300

I hope I can explain clearly...

best regards

Hi nedash,

Try with below sample code

C#

string str = "<div id='14921567137600375'><script type='text/JavaScript' src='https://www.aparat.com/embed/gRamq?data[rnddiv]=14921567137600375&data[w]=7214'></script></div>";
string filteredString = str.Replace(str.Substring((str.IndexOf("&data[w]=") + 9), (str.IndexOf("'></script>") - (str.IndexOf("&data[w]=") + 9))), "300");

hi anandM

I tested your code but it save in data bas

7214

I want it save this code:

<div id='14921567137600375'><script type='text/JavaScript' src='https://www.aparat.com/embed/gRamq?data[rnddiv]=14921567137600375&data[w]=300'>

attention at the end of code:

&data[w]=300'

I want when users enter above code in textbox it will save all above code in database and just change @data[w]=7214(or other number)"

to @data[w]=300...

best regards
