In my smart contract, I have a struct like this:
struct RewardInfo{
uint256 capitals;
uint256 statics;
uint256 directs;
uint256 diamond;
uint256 royalDiamond;
uint256 luck;
uint256 top;
uint256 royl;
uint256 dvlptFund;
uint256 dvlptFundDebt;
uint256 roi;
uint256 level2Freezed;
uint256 level2Released;
uint256 level3Freezed;
uint256 level3Released;
uint256 level4Freezed;
uint256 level4Released;
uint256 level5Freezed;
uint256 level5Released;
uint256 level6Left;
uint256 level6Freezed;
uint256 level6Released;
}
mapping (address => RewardInfo) public rewardInfo;
But becuase of member limitation of a struct in solidity, its showing stack too deep error. So, I broke the one struct into two as follows:
struct RewardInfo{
uint256 capitals;
uint256 statics;
uint256 directs;
uint256 diamond;
uint256 royalDiamond;
uint256 luck;
uint256 top;
uint256 royl;
uint256 dvlptFund;
uint256 dvlptFundDebt;
uint256 roi;
}
struct LevelInfo{
uint256 level2Freezed;
uint256 level2Released;
uint256 level3Freezed;
uint256 level3Released;
uint256 level4Freezed;
uint256 level4Released;
uint256 level5Freezed;
uint256 level5Released;
uint256 level6Left;
uint256 level6Freezed;
uint256 level6Released;
}
mapping (address => RewardInfo) public rewardInfo;
mapping (address => LevelInfo) public levelInfo;
Now, my problem is I want only one result of the mapping as follows:
mapping (address => RewardInfo) public rewardInfo;
But, since I have broken one struct into two, I have two:
mapping (address => RewardInfo) public rewardInfo;
mapping (address => LevelInfo) public levelInfo;
My question is, how do I merge the mapping into one and get only one as rewardInfo:
mapping (address => RewardInfo) public rewardInfo;
or any workaround? Any suggestion, how do I solve this problem?
Thank you very much in advance.

I have a simple NFT contract and trying to extract the number of tokens using _tokenIds.current(); but after deployment I call the function and it gives me this : BN { negative: 0, words: [ 0, <1 empty item> ], length: 1, red: null } while I am expecting a uint 256.

I want to call transferMoney() function which should send value (requests[_id].value) to an address address(uint160(requests[_id].provider)) with the transfer function of solidity. When I call this function via my DApp-Frontend using MetaMask, first I get the confirmation but the transaction gots reverted by the EVM. On etherscan, I see the status = fail. My aim is to send value from contract owner to another account.
What could cause the problem?
Here is the transaction hash on etherscan ropsten testnet: 0x30cef6bc33a25aeb4693a7c463ddf5dd597e0bd2c2ceb47feb38f29599feb4aa

I'm trying to use spring-data-cassandra (1.1.2.RELEASE) and I'm running into an issue with the lack of embeddable type mapping in JPA parlance.
I have an entity class like this:
#Table
public class Customer {
private UUID id;
private String name;
private Address address;
public UUID getId() {
return id;
}
public void setId(UUID id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
}
and the embeddable Address class:
public class Address {
private String address;
private String city;
private String state;
private String zip;
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
public String getZip() {
return zip;
}
public void setZip(String zip) {
this.zip = zip;
}
}
My cassandra table:
create table customer (
id uuid primary key,
name text,
address text,
city text,
state text,
zip text
);
I want the properties of Address to be mapped into the containing entity, I don't want a separate table for addresses. In JPA, I believe I'd use an #Embeddable annotation. Is there some similar construct in spring-data-cassandra?
Embeddable types are not yet supported by spring-data-cassandra. A feature request is available at DATACASS-167.
The only possible part of an entity to embed is the primary key. If your primary key consists of multiple fields, you can externalize that fields into a separate class and use it afterwards with the #PrimaryKey annotation.
Comment.java
#Table("comments")
public class Comment {
#PrimaryKey
private CommentKey pk;
private String text;
}

#PrimaryKeyColumn(ordinal = 0, type = PrimaryKeyType.PARTITIONED)
private String author;
#PrimaryKeyColumn(ordinal = 1)

I'm using Windows 7 RTM and I wonder how the control panel is able to update the Aero Glass color so smoothly without restarting the DWM (uxsms). DwmSetColorizationColor isn't working any more...
The following methods should be of interest to you:
[DllImport("dwmapi.dll", EntryPoint = "#127", PreserveSig = false)]
public static extern void DwmGetColorizationParameters(out WDM_COLORIZATION_PARAMS parameters);
[DllImport("dwmapi.dll", EntryPoint = "#131", PreserveSig = false)]
public static extern void DwmSetColorizationParameters(WDM_COLORIZATION_PARAMS parameters, uint uUnknown);
public struct WDM_COLORIZATION_PARAMS {
public uint Color1;
public uint Color2;
public uint Intensity;
public uint Unknown1;
public uint Unknown2;
public uint Unknown3;
public uint Opaque;
}
Make sure you make a call to DwmIsCompositionEnabled before calling the DwmSetColorizationParameters method or it will fail.
As you can see some of the arguments/properties are unknown.
