• Why are my "+" characters turned into spaces in my CGI program that handles Ajax requests?

  - by Dr.Dredel

  I'm collecting text through a web form and noticing that when it is collected by my Perl CGI all instances of "+" are transformed into " ". I run the text through a JavaScript escape before submission, but escape seems to leave + unaltered. There must be something really obvious that I'm missing... how do I send the string "2 + 2 = 4" through and not have it arrive as "2 2 = 4"?

• How to stop DataGridView from polluting my Designer file with column controlls?

  - by BeowulfOF

  I'm sure you know the problem, as soon as a BindingSource is connected to a DataGridView the DataGridView generates columns for each Property found in the Type of the BindingSource's DataSource and adds that crap to the Form.Designer.cs file. We only use run time generated columns, the clutter in the designer file is just waste of code, so how can we stop this "feature" of the DataGridView in WinForms?

• Custom HTML in a day with FullCalendar?

  - by drewjoh

  Is there a way to add, specifically, form elements for every day that are distinguishable per day? Below is an example. I know FullCalendar is built to handle "Events", so from what I can tell in the docs, it's not really possible. But I'm not a Javascript guru either, so would anyone else know of a solution? I'm hoping to not have to reinvent the wheel.

• Is it bad to use a model directly from a view in codeigniter?

  - by jason

  I know normally the data is passed thru to the view with the controller. however, currently in my view I load my model ($this-load-model('Db_model');) so i can use it in a loop to retrieve a users profile picture path from a array of IDs that is passed from controller. Will loading the db model in the view to accomplish this make my site more vulnerable or bad form? To me it seems to be outside of MVC concept but its working atm. thanks

  Hi, in my Django (1.2) project, I want to prepopulate a field in a modelform, but my new value is ignored. This is the snippet: class ArtefactForm(ModelForm): material = CharField(widget=AutoCompleteWidget('material', force_selection=False)) def __init__(self, *args, **kwargs): super(ArtefactForm, self).__init__(*args, **kwargs) self.fields['material'].initial = 'Test' I also tried with self.base_fields, but no effect: there is always the database-value displaying in the form.

The purpose of this is to ensure that a helper utility is always available on the system, without having to distribute multiple files.

I am using Delphi 2010.
