  • passing an argument to a custom save() method

    - by Nick
    How do I pass an argument to my custom save method, preserving proper *args, **kwargs for passing to te super method? I was trying something like: form.save(my_value) and def save(self, my_value=None, *args, **kwargs): super(MyModel, self).save(*args, **kwargs) print my_value But this doesn't seem to work. What am I doing wrong?

  • Is there a Silverlight equivalent to "Application.OpenForms"?

    - by lightmeetsdark
    Basically, I'm trying to take information entered by the user on one page and print it out to another page via a "printer friendly" version, or report, of something. I have a MainPage.xaml that is, as the name suggests, my main page, but in a window there is the subpage AdCalculator.xaml where the user enters the information and PrintEstimate.xaml that is navigated to via a button on AdCalculator. I would like to be able to transfer the information entered in the textboxes from AdCalculator and print it out via text blocks in PrintEstimate. So in order to do that I have the following code: Views.AdCalculator AdCalc = new Views.AdCalculator(); string PrintCompanyName = AdCalc.CompanyName; string PrintContactName = AdCalc.txt_CustomerName.Text; string PrintBillingAddress1 = AdCalc.txt_BillingAddress.Text; string PrintBillingAddress2 = AdCalc.txt_BillingAddressLine2.Text; string PrintPhoneNumber = AdCalc.txt_PhoneNumber.Text; string PrintNumOfAds = AdCalc.txt_NumofAds.Text; string PrintRateOfPlay = AdCalc.Cmb_Rate.SelectedValue.ToString(); string PrintNumOfMonths = AdCalc.txt_NumofMonths.Text; string PrintTotalDue = AdCalc.txt_InvoiceSummary_TotalDue.Text; PrintEstimate PrintEstimatePage = new PrintEstimate(); PrintEstimatePage.txt_CompanyName.Text = PrintCompanyName; PrintEstimatePage.txt_CustomerName.Text = PrintContactName; PrintEstimatePage.txt_BillingAddress.Text = PrintBillingAddress1; PrintEstimatePage.txt_BillingAddressLine2.Text = PrintBillingAddress2; PrintEstimatePage.txt_PhoneNumber.Text = PrintPhoneNumber; PrintEstimatePage.txt_InvoiceSummary_NumofAds.Text = PrintNumOfAds; PrintEstimatePage.txt_InvoiceSummary_RateofPlay.Text = PrintRateOfPlay; PrintEstimatePage.txt_InvoiceSummary_NumOfMonths.Text = PrintNumOfMonths; PrintEstimatePage.txt_EstimateTotal.Text = PrintTotalDue; Only problem is, when I instantiate the new AdCalculator page, it clears the values, so nothing is actually retained as far as user-input goes. Following a lead from a colleague, I believe all I need to do is change the line Views.AdCalculator AdCalc = new Views.AdCalculator(); to Views.AdCalculator AdCalc = (AdCalculator)Application.OpenForms["AdCalculator"]; except the "Apllication.OpenForms" doesn't register. I know there are a lot of differences in the way C# code-behind is laid out for silverlight applications, so I didn't know if there was an equivalent that anyone knew about to "Application.OpenForms" that would help solve my issue or if there was any other way to go about getting my task done. Thank you very much!

    - by Driss Zouak
    I just deployed my app to my iPhone for the first time. Every time it launches it vibrates before running, and it runs fine. The build is a Debug | iPhone one of my app. Any ideas why it vibrates when it launches and how to stop that? It's definitely not something I coded up and I don't have any exceptions or issues when running in the simulator.

  • decorating a function and adding functionalities preserving the number of argument

    - by pygabriel
    I'd like to decorate a function, using a pattern like this: def deco(func): def wrap(*a,**kw): print "do something" return func(*a,**kw) return wrap The problem is that if the function decorated has a prototype like that: def function(a,b,c): return When decorated, the prototype is destroyed by the varargs, for example, calling function(1,2,3,4) wouldn't result in an exception. Is that a way to avoid that? How can define the wrap function with the same prototype as the decorated (func) one? There's something conceptually wrong?

  • How do I find the list of functions executed to build a page?

    I want the list of all functions executed to a certain point in code, somehow like debug_backtrace() but including functions not in the exact thread that leads to where debug_backtrace() is called. e.g : a(); function a() { b(); c(); d(); } function b() { } function c() { } function d() { print all_trace(); } would produce : a(), b(), c(), d() and not a(), d() like debug_backtrace() would

  • .NET Library for drawing tables with GDI+

    - by Jan Willem B
    I need to print the contents of a datagridview, simple text in rows and columns, with GDI+ in .NET to paper. To do this, I need to iterate over the rows, draw lines, iterate over the columns, calculate width, height, wrap the contents if contents do not fit on one line, etc. This is all possible, but is there a library that simplifies the drawing of tables in GDI+ and abstracts some of the difficulties away?
