QUESTION
I've got the following code to download a file being transmitted over TCP:
...ANSWER
Answered 2021-Jun-15 at 09:31TCP/IP connections are designed to be long-lived streaming connections (built on top of the out-of-order, no-guarantee, packet-based IP protocol).
That means that is.read(bytes) does exactly what the spec says it will: It will wait until at least 1 byte is available, OR the 'end of stream' signal comes in. As long as neither occurs (no bytes arrive, but the stream isn't closed), it will dutifully block. Forever if it has to.
The solution is to either [A] pre-send the size of the file, and then adjust the loop to just exit once you've received that amount of bytes, or [B] to close the stream.
To close the stream, close the socket. It kinda sounds like you don't wanna do that (that you are multiplexing multiple things over the stream, i.e. that after transfering a file, you may then send other commands).
So, option A, that sounds better. However, option A has as a prerequisite that you know how many bytes are going to come out of inputStream. If it's a file, that's easy, just ask for its size. If it's streamed data, that would require that, on the 'upload code side', you first stream the whole thing into a file and only then stream it over the network which is unwieldy and potentially inefficient.
If you DO know the size, it would look something like (and I'm going to use newer APIs here, you're using some obsolete, 20 year old outdated stuff):

I had a problem.
When i create map in MongoDB Example Shop
...ANSWER
Answered 2021-Jun-14 at 18:31The problem is MongoDB uses BSON format for storing documents. And it does not support Map objects now. There is an open issue to to add functionality close to what you're looking for. But as for now it's not implemented.
You may write your own deserializer to restore your Map object. After getting the document from the DB you'll have to transfrom certain properties into corresponding entities. Map in your case. Something like:

Error:
TS7053: Element implicitly has an 'any' type because expression of type 'string' can't be used to index type 'User_Economy'. No index signature with a parameter of type 'string' was found on type 'User_Economy'.
ANSWER
Answered 2021-Jun-12 at 10:28The type of the const type that you have defined now is string.
As the error suggests, the User_Economy interface has no index signature with a parameter of type 'string', i.e. something like:
QUESTION
I have implemented a Xdnd drop support implementation in VTK some time ago. It was working great except with Thunar file manager. All other file managers were working fine at the time. We dismissed this limitation a Thunar bug at the time.
The feature I implemented was very simple:
- Set the window of the application to be XdndAware
- Receive the position message and respond that we are ready to receive
- Receive the drop mesage and request a selection
- Receive the selection notify and recover the URI
- Convert the URI into something we can work with
Nothing fancy, I did not even touch the list type.
Fast forward a few years and now dolphin users cannot drop files correctly into our application. The URI is always the first file dropped since dolphin was started. Restarting our application has no effect. No bug at all with pcmanfm.
This is not a dolphin bug and files can be dropped on blender or firefox from dolphin without issues.
So there must be a bug in our implementation, but I've been staring at the code for some time and everything I tried had no effect, except for breaking Xdnd support completely.
Here are the interesting part of the implementation:

Answered 2021-Jun-09 at 05:47From some testing, the issue is with the preparation and sending of the XdndFinished ClientMessage back to the drag and drop source when handling the SelectionNotify event.

QUESTION
RSACryptoServiceProvider.Encrypt has an f0AEP parameter that can be set to "true to perform direct RSA encryption using OAEP padding (only available on a computer running Windows XP or later)".
The thing is... with OAEP you have parameters like the Hash, MGF Hash and the label. How do you set those with RSACryptoServiceProvider? And when not set what do they default to? Even if they can't be set they should still default to something I assume?
RSA.Decrypt(Byte[], RSAEncryptionPadding) seems a lot more versatile and like it ought to be the preferred method but I'm just trying to understand RSACryptoServiceProvider more as I inherited some legacy code that uses it.
...ANSWER
Answered 2021-Jun-01 at 17:24RSACryptoServiceProvider applies the default values (from RFC8017), i.e. SHA1 for both digests and an empty label. The .NET documentation does not describe this in detail. A hint regarding SHA1 can be found in the remarks about the overload Encrypt(Byte[], RSAEncryptionPadding). Ultimately, it has to be tested because of the sparse documentation.
For other digests other implementations must be used, e.g. RSACng. Even here both digests can only be selected identically. The label cannot be set (which, however, is usually not done either).
The C# implementation of RSA/OAEP by BouncyCastle allows to set the digests independently. Likewise, the label can be set (referred to as encodingParams). Here is an example for C#/BouncyCastle.
