Check if a cell contains same digits

[kelly mort]

Hi,

I am looking for a way to verify if a cell say A1 contains same digits like 1111, 2222, etc.

The Len will always be 4.

Thanks in advance

@Phouc,

These are both excellent and elegant solutions to the OP's first two questions! Great <del>incite</del> insight into the underlying mathematical structure of the problem!

I agree.

... you can use this somewhat compact code line to do your latest check...

MsgBox [AND(LEFT(A1)=MID(A1,2,1),MID(A1,3,1)=RIGHT(A1),LEFT(A1)<>RIGHT(A1))]

.. or using Phuoc's ideas and your notation

MsgBox [AND(MOD(LEFT(A1,2),11)=0,MOD(RIGHT(A1,2),11)=0,MOD(A1,1111)>0)]

 

[Rick Rothstein]

MsgBox [AND(MOD(LEFT(A1,2),11)=0,MOD(RIGHT(A1,2),11)=0,MOD(A1,1111)>0)][/code]

Good idea. If I am not mistaken, this can be "simplified" (using that word might be a stretch) to this...

MsgBox [(MOD(LEFT(A1,2),11)+MOD(RIGHT(A1,2),11)=0)*MOD(A1,1111)>0]

Just "changed" I think.

Interesting!!!

I am really learning more and new tricks each single moments. I really appreciate that

I agree.

Hi,
I just got into a trouble :


I decided to replace the "A1" with a variable from a user input and I start getting a syntax error alerts.

How do I fix that to take the variable?

Like
.....left(MyInput, 2), 11).......
I thought just taking away the square brackets will do the job yet my thinking was off the grid.

Do you remember when I said "If you are always checking only cell A1 and no other" in Message #29 ... that was because the square brackets require fixed cell references (basically, it is a shortcut notation for evaluating a formula that one might find in a cell). The square brackets are sort of an alternative method for using the Evaluate function. The Evaluate function, however, can use variables because its argument is a text string which means you can concatenate the variable into text string constants (or use VB string functions to embed the variable into the text argument) and pass that into the Evaluate function. So what Peter suggested in Message #31 could be written like this in order to use a variable instead of a cell reference.

MsgBox Evaluate(Replace("AND(MOD(LEFT(@,2),11)=0,MOD(RIGHT(@,2),11)=0,MOD(@,1111)>0)", "@", YourVariable))

Note 1: I have assumed your variable's name is YourVariable (change it an necessary)

Note 2: I used the @ symbol as a stand-in for your variable in order to avoid multiple concatenations and then used VB's Replace function to change those @ symbols to the value stored in the variable.

Yes I do remember that question.


It's fixed now.
