  • Delphi / ADO : how to get result of Execute() ?

    - by mawg
    I have declared AdoConnection : TADOConnection; and successfully connected to the default "mysql" database (so, no need to pass that code). Now, taking baby steps to learn, I would like to AdoConnection.Execute('SHOW DATABASES', cmdText); which seems to work ok, in the sense that it doesn't throw an exception, but I am such a n00b that I don't know how I can examine the result of the command :-/ Halp!

  • How to return children objects?

    - by keruilin
    I have -- what I think -- is a simple question. Here's my code: class Fruit < ActiveRecord::Base end class Apple < Fruit end class Kiwi < Fruit end Assume that I have all the STI setup correctly, and there are multiple types of Apple and Kiwi records in the table. From here... fruits = Fruit.find(:all) ...how do I return an array of just Apples from the fruits array?

  • Entity framework not loading relationship even when using include

    - by dilbert789
    I have this code: Category selectedCategory = (from c in DB.Category.Include("SubCategory") join a in DB.Accessory on c.AccCatUID equals a.Category.AccCatUID where a.AccUID == currentAccessory.AccUID select c).FirstOrDefault(); It works fine, selectedCategory gets populated as expected. BUT selectedCategory has a child table 'SubCategory' which does not get loaded even though there is the include there. It is not loaded until I do this: selectedCategory.SubCategory.Load(); Why do I have to call load explicitly in order to load the child table?

    - by Daniel Granger
    I need my user to input some data like DF-DJSL so I put this in the code: theTextField.autocapitalizationType = UITextAutocapitalizationTypeAllCharacters; But unfortunately what happens is the first to letter type in CAPS but then letter immediately after typing the hyphen will be in lower case and then the rest return to CAPS therefore producing output like this (unless the user manually taps the shift button after typing a hyphen): DF-dJSL How can I fix this? Many Thanks

  • Making a Simple 2-Bit Asynchronous counter in WinCupl

    - by Kevin M.
    /* ****** INPUT PINS **********/ PIN 1 = clock ; /* clock input */ /* ****** OUTPUT PINS **********/ PIN 14 = Q1 ; /* output / PIN 15 = Q2 ; / output */ Q1.ck = clock; Q1.d = !Q1; Q2.d = !Q2; This is my code and the two lines below the output pins create a 1 bit ripple counter but I'm unsure how to transfer the output of the first flip flop to be the clock input for the second flip flip.

  • XSLT: opening but not closing tags

    - by farhad
    Is there a way to open a tag and not close it? For example: <xsl:for-each select="."> <span> </xsl:for-each> This piece of code is not valid because XSLT is not well formed, but is there a way to do a similar thing? Thank you

  • Right edge border unpainted & theme drawing on non client area

    - by CodeVisio
    Basically, the problem concerns border flickering during window resizing on Windows. My first goal was to repositioning controls on a dialog during resizing of it. I think I got a good dynamic repositioning without almost any flickering during this operation, but here I'm talking about main window border flickering. However, I wasn't able to eliminate it at all. To simplify the example try to create a simple win32 app with default code VS provided. I'm testing it on Window 7(64bit) with the default theme (Windows 7 basic, no transparency) and VS2008. 1) Do not add code to the app. 2) run it in debug mode. 3) Drag the left edge of the window slowly toward the left of the screen and at the same time keep an eye on the right edge border of the window. You should see a redrawing taking in action. 4) Repeat step 3 moving rapidly the mouse, you should see the flickering on the right edge more clearly. If you invert the edge, that is moving the right edge of the window, then the left edge stay firmly there without unpainted regions. The same process happens for the top edge border vs. the bottom one. Now, enable he Classic Theme (that similar to Win2000) and repeat again the steps above. The right edge is perfectly there without flickering at all! If you keep an eye in the Output Window of Visual Studio when you run in debug mode you should see a list of dll loaded together with your exe. If you run in debug mode with the default theme you will see uxtheme.dll loaded. On the contrary, with classic theme enabled the uxtheme.dll is not loaded (dwmapi.dll is always loaded). Probably uxtheme.dll is loaded at runtime, based on desktop settings and it takes in action for redrawing your windows non-client area. Another trick you could use to see the effect of this flickering is to add a case for WM_NCPAINT and return 0 instead to call the DefWindowProc(). Repeating the steps above and moving fast you should see a big part of the right edge of the window completely erased by background windows. This doesn't happen for the top and bottom ones. Any idea to resolve this flickering? Thank you!

  • Python mistaking float for string

    - by wrongusername
    I receive TypeError: Can't convert 'float' object to str implicitly while using Gambler.pot += round(self.bet + self.money * 0.1) where pot, bet, and money are all doubles (or at least are supposed to be). I'm not sure if this is yet another Eclipse thing, but how do I get the line to compile? Code where bet and money are initialized: money = 0 bet = 0

  • gcc compiling error on Solaris 10

    - by osman toker
    I want to compile a source code, but there are some compiling errors about __sync_xxx functions (__sync_bool_compare_and_swap etc.) GCC version on machine is 3.4.3 (it must be gcc 4.1 or over for supporting atomic builtins), so I have downloaded GCC v4.6, copied it to another directory (I didn't remove v3.4.3) then change the $PATH path for GCC but it doesn't work (the same error occurs). I want to ask that is only changing gcc path with export PATH=... enough for compiling with new GCC?
