Learning Solidity : Tutorial 5 Event logging and Transaction Information

If you would like to donate some Ethereum my wallet is: 0xC8c8c3Fae80e3eD236970e1C93AcF5B91D0993e2
Many thanks!

For anyone watching this and having trouble testing, make sure at the end when you're sending a value to the fallback to change the box on the right that says "wei" to "ether".

Simple and Short. Great Job... thanks!!!

[jagdishbelapure]

Excellent presentation and tutorials... Thank you very much!!

[RamBabu-mzcz]

Nice, easily understandable. Great Job

[gustavof]

Thank you very much!! Just one question, these (assert, require) are better than using 'if' or are just a simplification?

[LuserUploads]

Great tutorials, I appreciate. Just subscribed to your channel :).

Thank for your sharing. I have seen to tutorial 24 (Multi-Signature-Wallet). In my opinion, I want to send text message into transaction to someone wallet but not value. What should I do?

[dayone]

does anybody know What Event is for ? I still do not understand how it works out

Hello ;) Great Job!) Thanks for lessons. But at the moment i have an issue. When i clicks on (fallback) function, nothing is happens. Can you assist me, please ?:)

[princejohn]

Can you throw more light on who is an owner?

I get the error that the constructor has to be payable in order to send value. Btw my remix window looks very different from yours: among other things I get warnings if I don't specify the visibility of each function.

Hi,
when i tried to execute above code, i got error as "Transact to transition.(fallback) pending...", please help

[vertigo]

07:10 iirc 1 ether = 1 quintillion wei. 1 x 10^18 wei = 1 ether.

[chiragshahckshhh]

I am getting the warning before compilation as:
Fallback function of contract requires too much gas (2460).
If the fallback function requires more than 2300 gas, the contract cannot receive Ether.

And after running the program, I get this error:
transact to errored: Cannot read property 'op' of undefined

Please help. The code is same as the one you have mentioned in your github repository, only solidity version and compiler versions are 0.4.18.

I had a minor issue I couldnt figure out for a little while. The code works fine. Do in this order: hit the create button in Remix. Then in the remix ide, in the Value field below the Gas Price field, enter a value greater than the value of ether in the validValue modifier method. Then hit the fallback button and you can see your logging in the details view of the console window. I was trying to run the script before without realizing that I needed to add an ether value amount in the Value field, and I was getting an error that said "transact to errored: VM error: invalid opcode."

[mushahidkhan]

what are senderLogger(msg.sender) and valueLogger(msg.value) doing??

[viswanathansankar]

The compiler is asking to make the constructor to be payable. Can anyone clarify me why is that so?

[parthi]

I am not understanding the logic of owner being sender of ether to his own address. That is not reality right?

[porshb]

I've created the contract successfully, but when I enter a value and then click 'fallback' nothing happens.
