I am trying to write a program in Haxe but I got stuck on trying to convert a string to hex. I found a solution but I couldn't get it working. Can anyone help?
To convert a string in hexadecimal format into an integer:
final hex = Std.parseInt("0x00");

Help me please! I have date to string fotmat in
2023-02-13 00:00:00.00000000
Any conversion ends with an error. tried a lot of ways. Has anyone experienced something similar?
I try this
PARSE_DATETIME('%m/%d/%Y',date) PARSE_DATE('%m/%d/%Y',date) PARSE_TIMESTAMP("%Y-%m-%d%H:%M:%S%Ez"
and many more tries...
Failed to parse input string "2023-02-13 00:00:00.000000000"
how to convert it correctly?
is it possible to take out the first part of the date and convert it?
I try this
PARSE_DATETIME('%m/%d/%Y',date) PARSE_DATE('%m/%d/%Y',date) PARSE_TIMESTAMP("%Y-%m-%d%H:%M:%S%Ez"

Sample string :<U+0424><U+0413><U+0411><U+0423> "<U+041D><U+0418><U+0414><U+041E><U+0418> <U+0438><U+043C>. <U+0413>.<U+0418>.<U+0422><U+0443><U+0440><U+043D><U+0435><U+0440><U+0430>
Just wondering is there any online convertor or node module to convert this value to a readable string,
not sure whether it is Unicode or not
Please suggest a online convertor or node module to convert the string to readable format
Here's a online conversion tool https://r12a.github.io/app-conversion/. Copy into the U+Hex and click convert. The < and > symbols don't get converted. I get some intelligible Russian characters. It looks like the name of a children's hospital.
I'm a beginner in Kotlin, I want to know how to generate a list of String from a string.
For example, from a string "**martin**", I want to have a list of string:
m.artin
m.a.rtin
ma.rtin
mar.tin
m.a.r.t.i.n
etc.
Thank you in advance for your help.
Do you mean convert arraylist to string, I really don't understand your question but you can read about Kotlin JoinToString method
Python 3.6
I converted a string from utf8 to this:
b'\xe6\x88\x91\xe6\xb2\xa1\xe6\x9c\x89\xe7\x94\xb5#xn--ssdcsrs-2e1xt16k.com.au'
I now want that chunk of ascii back into string form, so there is no longer the little b for bytes at the beginning.
BUT I don't want it converted back to UTF8, I want that same sequence of characters that you ses above in my Python string.
How can I do so? All I can find are ways of converting bytes to string along with encoding or decoding.
The (wrong) answer is quite simple:
chr(asciiCode)
In your special case:
myString = ""
for char in b'\xe6\x88\x91\xe6\xb2\xa1\xe6\x9c\x89\xe7\x94\xb5#xn--ssdcsrs-2e1xt16k.com.au':
myString+=chr(char)
print(myString)
gives:
æ没æçµ#xn--ssdcsrs-2e1xt16k.com.au
Maybe you are also interested in the right answer? It will probably not please you, because it says you have ALWAYS to deal with encoding/decoding ... because myString is now both UTF-8 and ASCII at the same time (exactly as it already was before you have "converted" it to ASCII).
Notice that how myString shows up when you print it will depend on the implicit encoding/decoding used by print.
In other words ...
there is NO WAY to avoid encoding/decoding
but there is a way of doing it a not explicit way.
I suppose that reading my answer provided HERE: Converting UTF-8 (in literal) to Umlaute will help you much in understanding the whole encoding/decoding thing.
What you have there is not ASCII, as it contains for instance the byte \xe6, which is higher than 127. It's still UTF8.
The representation of the string (with the 'b' at the start, then a ', then a '\', ...), that is ASCII. You get it with repr(yourstring). But the contents of the string that you're printing is UTF8.
But I don't think you need to turn that back into an UTF8 string, but it may depend on the rest of your code.
I have a php script creating an encoded value, for example:
m>^æ–S[J¯vÖ_ÕÚuÍÔ'´äœÈ‘ ®#M©t²#÷[Éå¹UçfU5T°äÙ“©”ˆÇVÝ] [’e™a«Ã°7#dÉJ>
I then need to decode this in a vb.net application
The problem is that value above can have any characters. And VB.net can't handle it:
dim strCryptedString As String = 'm>^æ–S[J¯vÖ_ÕÚuÍÔ'´äœÈ‘ ®#M©t²#÷[Éå¹UçfU5T°äÙ“©”ˆÇVÝ] [’e™a«Ã°7#dÉJ>"
So any suggestions how to deal with that value?
Try base64encode and base64decode. That may be all that you need!
If you actually need to have it written out in your VB.net source code, you could try base64 encoding it:
dim strCryptedString As String = Base64Decode('bT5ew6bigJNTW0rCr3bDll/DlcOadcONw5QnwrTDpMWTw4jigJggwq5ATcKpdMKyI8O3W8OJw6XCuVXDp2ZVNVTCsMOkw5nigJzCqeKAncuGw4dWw51dIFvigJll4oSiYcKPwqvDg8KwNyNkw4lKPg==');
I'm not sure what the library functions' real names are.
When you read the string, read it into a byte array instead of a string. Then use the numeric value for the characters when you do the decoding.
