After I have deployed a contract, I'm able to interact with the setter functions, as well as with the getter functions. However, after a day goes by, when i try to interact with the same contract again, that is still open and loaded on my remix I get a "pending" message when I try to set and change some variables like a different address. When I try to call a get function also nothing happens. I don't know how to interact with my deployed contract again.
When I reload the contract using the contract address "at address", it properly loads the contract if I select the right smart contract (containing the getter and setter functions) from the dropdown menu in the "deploy and run" page. However, the same problem occurs, that is: when i try to set a variable the transaction is not mined (pending indefinetly), and the call functions also dont read the data.
In order for me to move forward with my project I need to be able to access and interact with the contract if I need to change a variable which currently doesn't work...
Anyone has an idea how to solve this (probably trivial) problem? Thanks!

I am trying to deploy this contract
https://github.com/juustesout/EtherRanger/blob/main/EtherRanger.sol
to BSC Testnet, and I get this error in return :
"revert
The transaction has been reverted to the initial state.
Note: The called function should be payable if you send value and the value you send should be less than your current balance.
Debug the transaction to get more information. "
this is an example of a failed transaction on BSC Testnet

I tried forking multiple contracts from BSC, working tokens, but I always get the same error. I tried adding 'payable' to the constructor function, as other StackOverflow posts suggest, but no go. I have been reading any number of posts through Google Search, but I am getting nowhere.
The contracts compile flawless, no errors, no warnings, but they just won't deploy.
Could someone check if they can deploy this contract on BSC Testnet ? It may be a setting on my Remix or something, I am at a loss, I cannot tell where the error comes from.
I don’t know anything about this contract but I guess the hardcoded addresses for the IBEP20 and others are the problem. You need to deploy these contracts too and then pass their addresses to the interface addresses in your constructor.
But to connect to the BSC test network, you need to find the drop-down menu with a list of networks at the top of the MetaMask

I am studying how to make BEP-20 tokens. For this I copied the following contract in remix to be able to study it:
Contract in BscScan
If I copy the whole file and compile it in Remix, when I deploy it it doesn't show me any getters. No public view function appears. If I look at the contract displayed on the testnet, it doesn't have any supply of tokens either.
I separated the files and libraries for a better reading. And it is then, when I try to display it, that I get the following error:
VM error: revert. revert The transaction has been reverted to the initial state. Note: The called function should be payable if you send value and the value you send should be less than your current balance. Debug the transaction to get more information.
It gives me the feeling that this contract does not generate the tokens ... What am I wrong?
I managed to fix the problem. As I suspected, in order to deploy the contract I have to remove everything related to uniswap and cakeswap. This displays the contract correctly.
If you wanted to deploy the contract with the uniswap interfaces in injected web3, you would need the uniswap testnet.
I found a test address for cake here:

In our company, repository objects must be created with original language EN.
Is there a way to check the logon language in case of creating a new object in the ABAP repository?
Desired behaviour:
SE80 - Create program/class/data element/table/....
==> user exit/badi checks the logon language. When it is not 'EN', the creation will be refused.

Umar Abdullah
I know there is a exit for this but I haven't remember exact name. You can use general purpose for finding exit. Go to SE24 and open CL_EXITHANDLER class, find GET_INSTANCE method and add break point. Then start creating item, it will pause on debugger multiple times, try to find suitable one.
As #mkysoft suggested, you may implement a check in the BAdI CTS_REQUEST_CHECK, method CHECK_BEFORE_ADD_OBJECTS, which is invoked when the object is about to be attached to a transport request. Raise the exception CANCEL to make the attachment fail (and so the object is not created too).
EDIT: sorry, ignore my answer, "this method is NOT released for Customer usage" as said in note 2150125 - Method CHECK_BEFORE_ADD_OBJECTS not triggered
DISCLAIMER: THE METHOD DESCRIBED HERE IS ABSOLUTELY NOT RECOMMENDED.
As correctly pointed out by the other members there is no standard and customer-exposed method to achieve your requirement, but if you absolutely must enable this check during creation you can use the below method. As well as the previously offered to you, it also involves modification of SAP standard.
There is a system BAdi CTS_TADIR_SUBSCREEN that is located inside enhancement point CTS_ES_TADIR_POPUP. They are SAP internal and not released for customer usage, so do this at your own risk.
Implementation procedure:
Step 0. First thing you need to change is a SAP internal usage flag, for which you need Object Access key which can be obtained from SAP or from SAP partner that made the implementation in your org. In virgin state this BAdi throws the error if you try to implement it
So hereinafter we assume that you already ticked off this checkbox in BAdi settings
Step 1.
In order to implement the BAdi one need to implement enhancement spot prior to that. This is the most complicated part, because despite we disabled internality flag the SAP-namespaced enhancements must be stored only in SAP-namespaced objects. By SAP namespace I mean non-Z, non-Y and non-T (Test). This means to implement this enhancement, besides modifying the enhancement definition, one need to create, for example, CTS_ES_TADIR named enh.impl., and save it to non-Z package, which you also need to create. Your enhancement implementations selector should look somehow like this
On the above screen only the second will work, all the rest Z will not.
Every non-Z object need Object Access Key, remember? Too bad. But just to show the proof-of-concept, I will proceed.
Step 2. After you created the enh. implementation in SAP-namespace it will propose you to create the BAdi implementation. The same principle applies here: only SAP-namespaced container for SAP-namespaced objects, hence CTS_TADIR_SUBSCREEN should have implementing class for example CL_TADIR_SUBSCREEN. During the creation of enhancement you will see many warnings
but finally you should have something like this, where all system-named objects are created and the enhancement/BAdi is activated.
Step 3. In order to get the BAdi working we need to enable this subscreen processing
during the playing with enhancement I found out that BAdi class is not being triggered standalone, without screen events not enhanced, so to make it work you need to touch a screen enhancement for screen 100
If you do not wanna modify screen elements logic, just put the dummy enhancement in SHOW_TADIR dialog module in the end of the include LSTRDO18
PROCESS BEFORE OUTPUT.
MODULE SHOW_TADIR. "<-- create the dummy enhancement here
CALL SUBSCREEN subs_info INCLUDING gv_badi_prog gv_badi_dynnr.
for example declaration statement like I did
Step 4. Activate your created BAdi class and put the necessary logic there. I wasn't able to trigger method GET_DATA_FROM_SCREEN, but PUT_DATA_TO_SCREEN worked fine
If we put this simple processing for your requirement
METHOD cts_if_tadir_subscreen~get_data_from_screen.
IF object_data-l_mstlang <> 'E'.
MESSAGE 'Objects in non-English languages are not allowed!' TYPE 'A'.
ENDIF.
ENDMETHOD.
it will not allow creating objects in languages other than English.
The check in method get_data_from_screen is being done before showing the screen so language is determined from system logon settings. If to play more with this BAdi, I suppose the method GET_DATA_FROM_SCREEN can also be enabled, which will make it possible to check user input, i.e. the case when the user gonna change the default language.
I finished the https://www.ethereum.org/crowdsale tutorial in Ethereum and intentionally left the crowdsale having failed its funding goal (sample code at the start of the page). I fired the "safeWithdrawal" function from within Ethereum-Wallet and it adds the transaction on to the blockchain. But at this point I do not know how to listen to the response. The ether I sent was not returned.
I would like the ether to be returned.
I would like to know how to listen to the event that should have fired. Or any feedback mechanism to know that the why / how the event fired.

Currently, the Ethereum-Wallet has no debugger built-in for smart contracts.
I suggest, you code up your example using the browser-solidity. It allows you not only to code and test the deployment but got most recently a debugger built in. Click the little bug.
The debugger used in browser solidity is remix which is both a javascript IDE but also a library which can be attached to your own javascript projects. It is possible that future releases of Ethereum-Wallet will also include remix, this would simplify your task pretty much.
But for now, the mentioned browser tool seems like perfectly suited for your needs.
I've spend days trying to find a solution the problem i'm going to try to describe, i've googled alot and even looked at the .NET 4 reference source for SendReply and InternalSendReply activity. But until now i'm stuck.
To make the life of our end customers simpler i want to replace the Receive and SendReply activities with custom activites and use bookmarks instead.
I'm implementing a central webservice which can route to a correct workflow instance, that workflow modifies the bookmark value and finaly it creates a new bookmark while returning the modified bookmark value. It's rather complex already with a WorkflowServiceHostFactory which adds Behaviours and Attach a DataContractResolver to the endpoint.
The endpoint is derived from WorkflowHostingEndpoint which resolves a bookmark created in a custom activity (instead of a receive). And i want another activity instead of a sendreply. Those 2 should correlate and the custom sendreply does send a response on the open channel through the endpoint while creating a new bookmark.
The problem is that i didn't find a way yet to access the endpoint responseContext from within my custom send activity. On the other side, at the workflowcreating endpoint side, it seems that i'm not able to be notified whenever the workflow becomes Idle and as well i don't seem to be able to access the WorkflowExtensions from the host. i'm missing something?
A possible solution i've in mind might be not using a WorkflowServiceHost, but then i loose alot of AppFabric functionaly.
The workflowapplication in platform update 1 has some extension methods called RunEpisode with an overload Func called idleEventCallback. There it's possible to hook into the OnIdle and get a workflowextension to get the object to send back as response.
To answer my own question, i ended up in a workaround using the servicebroker functionality of sql server. The SqlDependency class where the workflow listens for the event to be fired whenever the workflow reach the activity that creates a new bookmark in another state.
