Read the data as string using: string input = bluetooth.readString(); Then convert string to int using: int servopos = int(input); Then write the position to the servo:servo.write(servopos); Now depending on the data you send from android, you could need to : Trim it: input = input.trim(); Or constrain it : servopos = constrain(servopos,0,180); Your corrected … Read more
You want that $ in either case. Instead of ‘slash OR end’, it’s more ‘optional slash and then a very much not-optional end’. So.. /?$. You don’t need to normally escape slashes, especially in java regexes: Pattern.compile(“[-/](\\d+)/?$”) This reads: From minus or slash, a bunch of digits, then 0 or 1 slashes, then the end. … Read more

Add one more else if to your code: else if (key === “score”) { const low = filters[key] === “20” && user[“score”] <= filters[key]; const medium = filters[key] === “50” && user[“score”] < 50 && user[“score”] >= 21; const high = filters[key] === “70” && user[“score”] < 70 && user[“score”] >= 51; const veryHigh = … Read more
or is there another way to grant ALL PRIVILEGES and REVOKE the special one? NO, there is not any shortcut to do this. You will have to revoke ALL PRIVILEGE from user and then GRANT for each table separately. REVOKE ALL PRIVILEGES ON db.* FROM ‘carl’@’%’; Though there is option for automating this task of … Read more
Well first of all, you’re passing a Color3 pointer into an overloaded function that takes two different references. You have a range of options: Don’t pass a pointer (you have Color3 color in main(), don’t pass &color, pass color) De-reference the pointer to pass a reference (having a Color3* color in main(), pass *color not … Read more
Your first code will also work if the element you reference is part of the document at that time, so make sure to put the script near the end of the document, or else wrap it in the ready handler: $(function () { $(‘#delete-btn’).on(‘click’, function(){ return confirm(‘Are you sure you want to delete this?’); }); … Read more
I can only assume that a side effect of calculateSomeValue() is changing a which invalidates all iterators. Since the order of evaluation of arguments in a.insert(a.begin(), calculateSomeValue()); is unspecified it could be that a.begin() is evaluated before calculateSomeValue() invalidates all iterators to a. Which is undefined behaviour. solved discussion about the scenarios that the insertion … Read more
Well…this question raises plenty of others, but if you’re wanting to check if an object passed into a method is a TextBox, and then to set the Text property of that, you’d need: private void ChangeText(object target) { var tBox = target as TextBox; if (tBox != null) tBox.Text = “new value”; } EDIT This … Read more
You’re defining the variable entry inside the body of a method, this does not make entry accessible to the global scope, this is how you should embed objects: class Page1(Page): def __init__(self, *args, **kwargs): Page.__init__(self, *args, **kwargs) self.label = tk.Label(self, text=”This is page 1″) self.label.pack(side=”top”, fill=”both”, expand=True) self.entry = tk.Entry(self) self.entry.pack() As you can see, … Read more
You can’t insert boolean conditions into the function this way: if (!strcmp( yn , “y” || yn , “Y”)) change the conditions to first evaluate the boolean result of the functions and then perform your logical comparison if (!strcmp(yn , “y”) || !strcmp(yn , “Y”)) Also notice that you’re missing #include <cstring> to use strcmp … Read more
figured it out, set image as binary in model @RequestMapping(value = “/update”, method = RequestMethod.POST, consumes = “multipart/form-data”) public ResponseEntity<Payee> update(@RequestPart(“payee”) @Valid Payee payee, @RequestPart(“file”) @Valid MultipartFile image) throws IOException { // routine to update a payee including image if (image != null) payee.setImage(new Binary(BsonBinarySubType.BINARY, image.getBytes())); Payee result = payeeRepository.save(payee); return ResponseEntity.ok().body(result); } solved Post … Read more
In Python 3, input returns a string. You can’t perform modulo on a string. So you need to make it into an integer. number = int(input(‘Enter a number:’)) solved Determining Odd or Even user input
try result = result.map(function(obj){ Object.keys(obj).forEach(function(key){ key.indexOf(“b”) == 0 && delete obj[key]; }); return obj; }) And to call it as result.letters instead of directly as result make the following modification var letters = result.map(function(obj){ Object.keys(obj).forEach(function(key){ key.indexOf(“b”) == 0 && delete obj[key]; }); return obj; }); result = { letters: {}}; letters.forEach(function(obj){ var keyName = Object.keys(obj)[0]; … Read more
