Zcash4win BETA is out!

[Unconformed]

I tried to do this and got the following:

Can anyone help?

[Unconformed]

Hey - I just did this for the second time. Is there away to fix bugs without DL the whole block chain each time?

[CitricAcid]

in the screenshot you posted, it tells you the exact issue. Once you do what it says, it should pick up from the last synced block

Error in sending cash…

I truly want you to read the error code and please understand why it failed. Think about it, Zcash to a btc account.

Looks like your download of the blockchain is corrupt. Try to reindex.

[jpl]

So I can’t convert zec to btn on coinbase and then to my account? I thought that is how it worked.

… edit.

how to convert my wallet zec to usd

[CitricAcid]

@jpl

I thought that is how it worked.

I’m not sure if your serious or pulling my leg

just in case Common Questions and Answers

[Unconformed]

Thanks, I figured that so I just DL the whole thing again. I got to 93% this time. What is the re index command?

Is it a re scan?
cd “c:\Program Files\zcash4win\app”
.\zcashd.exe -rescan -daemon=0 -showmetrics=1

Edit - I read David’s post and installed a new version. A case of trying to do things the hard way when simple uninstall / re-install is all it takes.

Hi mate

I got to the same issue again. 3 Questions

1. How do I upgrade to the latest version of zcash?
2. To set the value, do I just type is into the directory listed in my screenshot (i tried this, nothing happened and same result). Do I have to pass the cli anything else to make this command work? Do I put it into a config?
3. Are there any disadvantages of passing the system the value in the screenshot, as opposed to upgrading Zcash?

Edit - I read this - and I have a slightly better idea now. However, reading that, I am wondering how to upgrade using the zcash wallet? Everything has occurred inside the zcash wallet experience. In my Linux box (which I could not run for AGP compatibility reasons), I could easily update zcash. In windows, with this wallet, I am unsure how.

Happy to be shown how to apply the value above for now, but I wonder is there a long term solution?

Add getdeprecationinfo RPC method to return deprecation block height

Hello @anon47418038! First I want to say thank you for making the Windows Zcash wallet. I have found it useful so far. Today I ran into an error on the latest 1.0.12 release. When I try to send zcash from my T-addr to my Z-addr, the wallet gives me this error:

general exception: std::bad_alloc

Do you know what might be causing this issue and how I might solve it?

[Uche32]

don’t know if this was already asked, but will there be a a new version against spectre and meltdown for zcash4win, if necessary at all?

[CitricAcid]

@Uche32

a new version against spectre and meltdown

That affects central processing units, to protect your information/data you should make sure you have the latest updates from Intel, AMD, O/S and smart devices. Warning, some updates have been known to crash the system.

Here is an article that breaks it down

Spectre and Meltdown explained: What they are, how they work, what's at risk

and

Intel’s Spectre patch is causing reboot problems for older processors

Win 10.

1. I backup wallet.dat from C:\Users\Serg\AppData\Roaming\Zcash
2. Delete folder C:\Users\Serg\AppData\Roaming\Zcash
3. reinstall zcash4win-1.0.12
4. start zcash4win, but it just created a new wallet
5. I copied the old wallet.dat file and used it to replace the wallet.dat file on a new install of ZCash4Win
6. start zcash4win, but my old wallet.dat Renamed to wallet.1516132245.bak
7. i rename wallet.1516132245.bak to wallet.dat
8. start zcash4win again “daemon is taking longer than expected”

I can’t see a way to edit my previous post, but I found the answer to my question here:

General exception: std::bad_alloc

Using the Swing Wallet GUI I try to make a z-to-z transaction and I get this error: An error occurred when sending cash. Error message is: general exception: std::bad_alloc Please ensure that the sending parameters are correct. You may try again later… I checked the parameters. The address and amount are both correct.

The error is letting me know that I do not have enough RAM allocated to the Zcash process.

[jpl]

Thanks,… yeah I’m only 2 months in…

[MDSS]

Hi. I’m running zcash4win and it looks like the transaction log only shows the mot recent 100 transactions from my wallet. Is there anyway I can get of list of all the transactions? According the the blockchain explorer, I have about 1,500 transactions from my account.

Thanks!
MDSS

[Autotunafish]

I had the same problem. I don’t know if there is a way to see them all, what I ended up doing was backing up the wallet and uninstalling, delete files, and then reinstalling to force the blockchain to redownload and just imported the private Keys when the GUI opened up. Then exported about one months worth at a time to a CVS file as they populate.
Edit-scroll up to post 929, bout 23 days ago

[MDSS]

Lol. That’s what I’ll have to end up doing unless someone has a more elegant solution.

BTW, with the ethereum wallet, there’s a file folder called chaindata. If you delete it, it’ll force the wallet to re-download the blockchain. It looks like for zcash4win, there are 2 folders - blocks and chainstate. I’ll try renaming them to see if it will force a re-download and will let you know.
