I am getting error with this line Doc Sir

Code:

---

Set Rng1A = Rng1.Range("A1:A" & Rng1.Rows.Count & ""): Set Rng2B = Rng2.Range("B1:B" & Rng2.Rows.Count & "")  ' : Set Rng2A = Rng2.Range("A1:A" & Rng2.Rows.Count & "")

plz have a relook Doc Sir

You should be able to see a possible problem ...
Where is your Rng1 and Rng1 defined????
You must have Rng1 and Rng1...
You are missing this

Code:

---

Dim Rng1 As Range, Rng2 As Range
 Set Rng1 = Ws1.Range("A1").CurrentRegion: Set Rng2 = Ws2.Range("A1").CurrentRegion

( Note also : It is very bad programming to use On Error Resume Next at the start of a program )

May i know the reason why it is bad Doc sir So that i can be safe with my work
I have not use this in every code but Now some modification is needed and as per requirement that line is needed but may i know the information Doc sir why i should not use that & what that line will do, it will only stop the Error msg only correct me doc Sir if i am wrong

On Error Resume Next is one of a few ways to do “Error handling in VBA” ( http://www.excelfox.com/forum/showth...GoRoT-N0Nula-1 )

On Error Resume Next at the start of your program will tell VBA to keep going even if it crashes or has problems many times.
It is like you go on a long journey in your car. But you decide to drive very fast and if you have lots of crashes and accidents you just keep going very fast and ignore all your accidents and crashes.
This can do damage and break things.

It does not just stop the error message. It does stop the error message , you are correct , … but also it does keep going even if things are broken or not working properly. This might do bad damage. You may not notice this damage until something else goes badly wrong. It may cause lots of confusing problems later.

On Error Resume Next at the start of your program is dangerous. You may be lucky one day and it will cause no problems. Or you may be unlucky and it will cause lots of problems and cause lots of damage.


Usually there is a better way to achieve what you want without Error Handling.


Some ways to use Error handling are not too bad.
For example:

This is very Bad

Code:

---

Sub BadErrorHandling()
On Error Resume Next ' Error handling is ON
Dim Nmbr As Long: Let Nmbr = 0

'
'  code
''  code
''  code
''  code
''  code
''  code
''  code
''  code
''  code
'

 Let Nmbr = 1 / Nmbr

 '
 '
 '  code
''  code
''  code
''  code
''  code
''  code
'
End Sub

---

This is not so bad

Code:

---

Sub NotSoBadErrorHandling()

Dim Nmbr As Long: Let Nmbr = 0

'
'  code
''  code
''  code
''  code
''  code
''  code
''  code
''  code
''  code
'
On Error Resume Next ' Error handling is ON
 Let Nmbr = 1 / Nmbr
On Error GoTo 0      ' Error handling is OFF
 '
 '
 '  code
''  code
''  code
''  code
''  code
''  code
'
End Sub

---

The last macro is not so bad because you only use the error handling for a short piece of the code which you think may error.

But it is still better to do it without error handling

Code:

---

Sub AlternativeToErrorHandling()

Dim Nmbr As Long: Let Nmbr = 0

'
'  code
''  code
''  code
''  code
''  code
''  code
''  code
''  code
''  code
'

    If Nmbr <> 0 Then Let Nmbr = 1 / Nmbr

 '
 '
 '  code
''  code
''  code
''  code
''  code
''  code
'
End Sub

Doc Sir i used this code but i am not getting desired result i think i have putted something incorrect plz have a look Doc Sir

No issue Doc Sir i have another plan for this i will not use that line Thnx for the guidance Sir but i am not getting the desired result plz look Sir

The last macro of yours ( http://www.excelfox.com/forum/showth...ll=1#post12882 ) looks OK

So do two things

_1) Upload a small sample data of
STEP1U.xlsb
And
1.xls


and

_2) tell me what is not doing what you want: Tell me what result is wrong

plz see the sample file Doc Sir i tried to explain the condition in the sample file doc sir

vba will be placed in a seperate file

Before:- ( from your uploaded files )
_____ Workbook: sample1.xlsx ( Using Excel 2007 32 bit )

Row\Col	A	B	C	D
1
2	ACC	150
3	DLF	120
4
5			match column A of sample1.xlsx with column B of sample2.xlsx
6			If it matches then do nohing
7			if it doesn’t matches then delete that enire row
