Is it possible to convert integer to 6 digit hex code? In AS3 I had native API
var color:uint = 0xFF00FF;
trace("Color #" + color.toString(16)); //Color #ff00ff
Does Haxe have such functionality in standard library?
You can use StringTools.hex()

i have activereport 6 and C# and i try to add 6 days to textbox1 value/text
this is what i try
string text1 = this.textbox1.Text;
i also try
string text1 = this.textbox1.Text.ToString();
or string text1 = this.textbox1.Value
convert string to time
DateTime date1 = Datime.Parse(text1);
i keep getting error "target of invocation"
how do i convert textbox data string to datetime? or how do i fix that target of invocation error?
That should be the correct way to get the text value from the textbox, as it is already a string.
string text1 = this.Textbox1.Text;
From there you should be able to use the standard .NET methods to convert it to a DateTime. The way you did it looks correct to me based on Microsoft's docs. However, that's assuming the format your string is in is one of the formats the DateTime.Parse() method understands by default. Example from their docs:
string dateInput = "Jan 1, 2009";
var parsedDate = DateTime.Parse(dateInput);
Console.WriteLine(parsedDate);
// Displays the following output on a system whose culture is en-US:
// 1/1/2009 00:00:00
If your string is in a different format from one of the handful that DateTime.Parse understands by default you may need to use a custom format, and I believe that could be the source of the error you're receiving.
How to display Unicode Smiley from json response dynamically in flutter. It's display properly when i declare string as a static but from dynamic response it's not display smiley properly.
Static Declaration: (Working)
child: Text("\ud83d\ude0e\ud83d\ude0eThis is just test notification..\ud83d\ude0e\ud83d\ude0e\ud83d\udcaf\ud83d\ude4c")
Dynamic Response:
"message":"\\ud83d\\ude4c Be Safe at your home \\ud83c\\udfe0",
When i'm parse and pass this response to Text then it's consider Unicode as a String and display as a string instead of Smiley Code is below to display text with smiley:
child: Text(_listData[index].message.toString().replaceAll("\\\\", "\\"))
Already go through this: Question but it's only working when single unicode not working with multiple unicode.
Anyone worked with text along with unicode caracter display dynamically then please let me know.
Another alternate Good Solution I would give to unescape characters is this:
1st ->
String s = "\\ud83d\\ude0e Be Safe at your home \\ud83c\\ude0e";
String q = s.replaceAll("\\\\", "\\");
This would print and wont be able to escape characters:
\ud83d\ud83d Be Safe at your home \ud83c\ud83d
and above would be the output.
So what one can do is either unescape them while parsing or use:
String convertStringToUnicode(String content) {
String regex = "\\u";
int offset = content.indexOf(regex) + regex.length;
while(offset > 1){
int limit = offset + 4;
String str = content.substring(offset, limit);
// print(str);
if(str!=null && str.isNotEmpty){
String uni = String.fromCharCode(int.parse(str,radix:16));
content = content.replaceFirst(regex+str,uni);
// print(content);
}
offset = content.indexOf(regex) + regex.length;
// print(offset);
}
return content;
}
This will replace and convert all the literals into unicode characters and result and output of emoji:
String k = convertStringToUnicode(q);
print(k);
😎 Be Safe at your home 🈎
That is above would be the output.
Note: above answer given would just work as good but this is just when you want to have an unescape function and don't need to use third-party libraries.
You can extend this using switch cases with multiple unescape solutions.
Issue resolved by using below code snippet.
Client client = Client();
final response = await client.get(Uri.parse('YOUR_API_URL'));
if (response.statusCode == 200) {
// If the server did return a 200 OK response,
// then parse the JSON.
final extractedData = json.decode(response.body.replaceAll("\\\\", "\\"));
}
Here we need to replace double backslash to single backslash and then decode JSON respone before set into Text like this we can display multiple unicode like this:
final extractedData = json.decode(response.body.replaceAll("\\",
"\"));
Hope this answer help to other
I am using FontAwesome to display glyphs in my Xamarin Android application. If I hardcode the glyph like this, where everything works fine:
string iconKey = "\uf0a3";
var drawable = new IconDrawable(this.Context, iconKey, "Font Awesome 5 Pro-Regular-400.otf").Color(Xamarin.Forms.Color.White.ToAndroid()).SizeDp(fontSize);
However, if what I have is the four letter code "f0a3" from FontAwesome's cheatsheet, stored in a string variable, I don't know how to set my iconKey variable to a value that works. Just concatenating a "\u" onto the beginning doesn't work, which makes sense since that's a Unicode escape indicator, not part of a standard string, but I don't know what to do instead. I also tried converting to and from Unicode in various random ways - e.g.
iconKey = unicode.GetChars(unicode.GetBytes("/u" + myFourChar.ToString())).ToString();
but unsurprisingly that didn't work either.
The IconDrawable is from here. The value I send becomes an input there to the Paint.GetTextBounds method and the Canvas.DrawText method.
Thanks for any assistance!
Found the answer here. Here is the code I am using, based on that post but simplified since I have only one hexadecimal character to handle:
string myString = "f0a3";
var chars = new char[] { (char)Convert.ToInt32(myString, 16) };
string iconKey = new string(chars);
var drawable = new IconDrawable(this.Context, iconKey, "Font Awesome 5 Pro-Regular-400.otf").Color(Xamarin.Forms.Color.White.ToAndroid()).SizeDp(fontSize);
I need to get the ASCII code of a Persian string to use it in a program. But the method below give the ? marks: "??? ????"
public string PerisanAscii()
{
//persian string
string unicodeString = "ØµØ¨Ø Ø¨Ø®ÛŒØ±";
// Create two different encodings.
Encoding ascii = Encoding.ASCII;
Encoding unicode = Encoding.Unicode;
// Convert the string into a byte array.
byte[] unicodeBytes = unicode.GetBytes(unicodeString);
// Perform the conversion from one encoding to the other.
byte[] asciiBytes = Encoding.Convert(unicode, ascii, unicodeBytes);
// Convert the new byte[] into a char[] and then into a string.
char[] asciiChars = new char[ascii.GetCharCount(asciiBytes, 0, asciiBytes.Length)];
ascii.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0);
string asciiString = new string(asciiChars);
return asciiString;
}
Can you help me?
Best regards,
Mohsen
You can convert Persian UTF8 data to Windows-1256 (Arabic Windows):
var enc1256 = Encoding.GetEncoding("windows-1256");
var data = enc1256.GetBytes(unicodeString);
System.IO.File.WriteAllBytes(path, data);
ASCII does not support Persian. You may need old school Iran System encoding standard. This is determined by your Autocad application. I don't know if there is a direct Encoding in windows for it or not. But you can convert characters manually too. It's a simple mapping.
m anew comer to iPhone...before i have developed for Android..Could any one tell me what is the alternate code in objective C..Thanx in advance
Int projectNumber = Integer.parseInt(projectNumber.trim());
int intProjectNumber = [[projectNumber stringByTrimmingCharactersInSet:whitespaceCharacterSet] integerValue];
edit:
Just to explain a bit more..
If you have a NSString named projectNumber (ie. #" 4 "). You can make a new string with trimed whitespace infront of the string and after the string with
NSString *trimedProjectNumber = [projectNumber stringByTrimmingCharactersInSet:whitespaceCharacterSet];
as you can see this replaces the trim() function
trimedProjectNumber would now be #"4". If you want an integer representation of this string you do:
int intProjectNumber = [trimedProjectNumber integerValue];
this replaces the parseInt..
I dont know java but i think this is what youre code does? If not explain what the java code does..
