Are you saying that you cannot figure out how to format a string containing some characters followed by a number?

ssd_coolguy 18-Jun-12 8:47am

yes.. i tried below code.... but no output :(
intmax = String.Format(intmax, "TXT00000")

I guess you need to spend some time learning VB.NET. String.Format() creates a string of text from a format template and optional parameters. So the following line of code:
string key = String.Format("TXT{0:000000}", keyvalue)
would create the string TXT000014 if keyvalue contains the value 14.

yes i will sure spend time to learn vb.net...

i got solution with below code also just check it...

intmax = nextno.ToString("TXT000000")

if intmax contians 14 then it will return TXT000014... :)Thanks..

I don't think so; please reread my response carefully and review the MSDN link that I gave you.
