setvalue

In Swift it's not possible use .setValue(..., forKey: ...) nullable type fields like Int ? properties that have an enum as it's type an Array of nullable objects like [MyObject?] There is one workaround for this and that is by overriding the setValue forUndefinedKey method in the object itself. Since I'm writing a general object mapper based on reflection. See EVReflection I would like to minimize this kind of manual mapping as much as possible. Is there an other way to set those properties automatically? The workaround can be found in a unit test in my library here This is the code: class

I'm really just curious, but does anyone know why you can't use setValue to write in different cell in a custom function? The readme explains that you can't do this, but doesn't give a reason on why: link Custom functions return values, but they cannot set values outside the cells they are in. In most circumstances, a custom function in cell A1 cannot modify cell A5. However, if a custom function returns a double array, the results overflow the cell containing the function and fill the cells below and to the right of the cell containing the custom function. You can test this with a custom

i have a form that uses a drop down and im using codeigniter , form helper and form validation so when i get a validation error in my form , all the correctly entered fields are populated using set_value of codeigniter , however this doesnt work for dropdown im doing : <?php echo form_dropdown('mid', $id_map, set_value('mid'), 'id="mid"') ?> when get error in form , always the first value of dropdown is selected and not previously set Any ideas , what am i doing wrong? The correct method to use set_select() is <select name="myselect"> <option value="one" <?php echo set_select('myselect', 'one'

Trying to understand what the 'onlySelf' parameter does when passing to setValue. this.form.get('name').setValue('', { onlySelf: true }) The documentation says: "If onlySelf is true, this change will only affect the validation of this FormControl and not its parent component. This defaults to false." However I'm struggling to understand this. Still fairly new to the using Angulars' model driven forms. Angular2 by default will check for the form control/form group validity cascadingly up to the top level whenever there's an update to any form element value, unless you say no. onlySelf is the

Is there a way to set a single value in an array property via reflection in c#? My property is defined like this: double[] Thresholds { get; set; } For "normal" properties I use this code to set it via reflection: PropertyInfo pi = myObject.GetType().GetProperty(nameOfPropertyToSet); pi.SetValue(myObject, Convert.ChangeType(valueToSet, pi.PropertyType), null); How would I have to change this code to set the value in an array property at an arbitrary position? Thanks! BTW: I tried to use the index parameter, but that seems only to work for indexed properties, not properties that are arrays...
