• Visual C++ Template Selection Visual C++ 2005

  Keyword C++ Template Matching Selection I thought in many circumstances the more specialized template is chosen. So the actual template selection by the great compiler seems contrary to my expectation. This concerns overloading the operator = via templates in a C++ class. Desired: To have member template methods (operator =) called in certain object types thus producing other or same objects. Expression Templates. I want to manually write these templates for the educational value. (template frenzy).( I dont want use boost::lamda ... just yet). Other metrics being equal .. I would like to use a lesser number of member functions. Actual: I get template matching that is contrary to my intention. (I dont understand the actual template ...Show All

• Visual C++ Visual C++ release build

  Hello, I am not a proffesionalist in Visual C++ (from Visual Studio 2005) so I need help. Can any one tell me if I can build a release version of my software which is Windows Forms Application with all needed dll's included in my application The problem is, that I can not install NET Framework on one computer in our company where I have to put my software. Does Visual C++ always need NET Framework Best Regards, Kamil Weather you build Release or Debug, if you are using any part of the framework in your program you'll always need .NET framework deployed in the target system. And since Windows Forms uses the .NET framework you'll need it on the target. ...Show All

• Visual C# Retrieving last index value in an ArrayList

  I want to populate an int variable with the last index of an ArrayList. I haven't yet found a property of ArrayList that will do that for me and I'm wondering if I'm missing something. Right now I am doing it this way: int theLastIndex = theArrayList.Count - 1 But I'm wondering if there is a more elegant way. This is in C#, by the way. Thanks in advance. Yes, that is correct. Normally, though, you should avoid basing too much logic around the last index of the array/ArrayList, and instead just use the size. Then instead of looping while, say, i <= lastIndex, you loop while i < arrayList.Count. This is something that I didn't do when I was first learning java, so I frequently had off- ...Show All

• Software Development for Windows Vista Using Windows SDK (With the Glass Effect)

  I have Windows XP and I downloaded Windows SDK for developing apps that are compatible with Vista, is it possible to make an app on XP with the glass effect or do I have to use Vista to create an app with the glass effect They do however have the Vista Minimize, Maximize, and Close buttons on some applications already for XP that's why I wondered, for instance on Windows Media Player 11 they have the shiny Vista buttons on the top right of the screen.

• Game Technologies: DirectX, XNA, XACT, etc. GameComponents In Depth With V1

  So I've been trying to read all I can about the features of XNA and one that I'm just starting to discover is the GameComponent system. I have a small knowledge of what's going on, but I can't seem to find much on how it works in V1.0. I Googled and found a video (http://blogs.msdn.com/xna/archive/2006/08/31/734204.aspx) but that covers back during beta 1, which was the same for most other sites. Does anyone have any links to sites that talk about GameComponents and how they work Or does anyone have a few minutes to go through them I'm looking for as in depth as possible so I can really see what I can do with them. Thanks in advance. Let's say you want to make a UserInterface drawable component.   ...Show All

• Software Development for Windows Vista Marked application(embedded manifest) doesn't elevate when UAC is turned off?

  Hi I'm testing my app on vista Business K. I've embedded manifest file and running it with shellexecute. It correctly gets elevated when UAC is enabled. However, when UAC is turned off, it won't get elevated as it should. Most surprisingly, one of two identical copies of the application has the windows security logo mark on the icon and one does not. I know the two files are identical for sure because their sha-1 checksums are identical and all other properties are the same(size and etc) What the heck is going on here Is UAC still buggy Thanks in advance. If you're writing a new app for Vista, I would strongly suggest you use a manifest with an appropriate requestedExecutionLevel, whether it nee ...Show All

• Commerce Server Order History Detail

  Hi, On the account history page (of the Commerce Server Starter Site), as well as, the last page of check out, my client would like to see the detail/items of the order. What is the best way to accomplish this. I am surprised on the Account History page that the order # is not a link to the detail which would have been nice feature. Please Advise. What do you mean by details of the item Keep in mind that when you are showing an Order, you cannot be sure that the product in the Order is still available on the site, so you cannot link to the product details from the catalog. All that you can show is the product information already stored in the Order (with the LineItem class). If you want to sh ...Show All

• Visual C# App Config and escape sequences

  Is it possible to read data from an app config file using the configuration manager without having characters being escaped automatically. I need to read a sequence from the app config file and have it available exactly as it is written. I.e. "\n\n\n\nABCD" should be read as "\n\n\n\nABCD", not "\\n\\n\\n\\nABCD". Can this be done The problem comes when I try and do a comparison. If agree that when I write irt out I get \n\n\n\nABCD, but when I try and compare it to a string containing \n\n\n\nABCD it fails since one conta9ins \\n\\n\\n\\nABCD and the other \n\n\n\nABCD. ...Show All
