VB Forum / VB Syntax / June 2008some characters are trimed
I pasted a string into VB editor form dreamweaver,and I found the string pasted modified by VB editor ,some characters had been trimed unawarely. the oringnal string "YndDPW6~E YkG^GNP" the trimed string "YndDPW6~E YkG^GNP" Does the trimed string look longer?if they are pasted into notepad,you will see the oringnal string has one more space between "YndDPW6~E" and " YkG^GNP" ,it is really confused ,what char on earth had VB editor trimed and why?the oringal string is part of my encoded script capulated in dll, the missing char made my script crippled. appreciate for your help.

This is just a guesss, you'd have to check this yourself, but I would not be surprised if the editor substituted Chr(8) (Tab character) out of your original string and added the requrired spaces needed to get to the next tab stop..... LFS I have checked and found that two space(char(32)) had been trimed,confused... > I have checked and found that two space(char(32)) had been trimed,confused... I agree, it is confusing that VB would trim a printable character when pasting.... LFS I checked again and found I was wrong,as your guess in VB editor a tab character (chr(9)) will be substituted by a space (chr(32)) automatically when pasted,so I tempted to solve this problem by this way:"YndDPW6~E" & chr(9) & "YkG^GNP",but when the string was output to the web page,I found the tab was substituted by space again! Is looks like tab can't get along with VB. > I checked again and found I was wrong,as your guess in VB editor a tab > character (chr(9)) will be substituted by a space (chr(32)) automatically > when pasted,so I tempted to solve this problem by this way:"YndDPW6~E" & > chr(9) & "YkG^GNP",but when the string was output to the web page,I found > the tab was substituted by space again!

Is that a function call, a document write thing, what (exactly)?

VB code(in class scriptClass): function outputScript() .......... response.write "...~E" & chr(9) & "YkG..." .......... end function I don't know if I illustate clearly enough,you know my english is poor. > well,my end is to encapsulate script in my ASP component,the component > will output the right script according to the client's request.I'll explain > it by a example As you see, writing encoded text may be problematic. How about a different solution? If you output your script to a .js file, you can use the SRC attribute of the SCRIPT tag to call that file: ScriptFile = ScriptObject.OutputFileURL Response.write "<SCRIPT lang = JScript.Encode src = " Response.Write Chr(34) & ScriptFile & Chr(34) Response.write "</SCRIPT> I don't do ASP, so I'm not sure if that is a solution or not. The point is you might look at other ways to include your script other than using the write method to send encoded characters.... If you use the src attribute, would the script really need to be encoded? LFS that is a good idea ,I will try. |
