• .NET Development .NET encourages poor coding?

  The more I look at .NET error handling, and how to deal with it, the more frustrating it gets. Take this class for example.   It has a single boolean property.   You have to know on which side of the call an error will be raised… by the caller or the callee… well here’s a prime example.    Say you have to read data from somewhere like a text file and you cannot ensure the format of the data is proper.   Well, you cannot depend on a property to check that data for you if you strongly type the property. Read the orange comment to see what I mean, and please let me know how you deal with this situation since to me it appears to require horrible program design.     Public Class ...Show All

• Windows Forms Prerequisite not working? (Possible solution)

  I'm trying to build a setup for my application using a Windows Installer project. I'm using VS2005. My Windows application requires SQL Server 2005 Express, so I marked that as one of the prerequisites. I built the installer successfully and ran it on one computer running XP. It successfully detected that neither .net 2.0 or SQL Server 2005 Express were installed and installed both of them before installing my application. My application ran just fine and life was good. I then took the exact same setup.exe and setup.msi and ran them on another computer - also running XP. It didn't attempt to install either of the prerequisites, and seemed to successfully install my application. As soon as my app was launched though it failed with " ...Show All

• Visual Studio Tools for Office GetObject and Createobject fails with Outlook 2007 RTM

  Hi, I have a VB.NET application (.net2.0). Running on Vista RTM with Visual Studio 2005 I have an application that used to do a GetObject(Class:= "Outlook.Application" ) and it always worked until I upgraded to Vista and office 2007.

• Visual C++ DLL without CRT

  Is it possible to create a dll without it's copy of the CRT, so that it would use one from the context of the calling process well, the thing is that i am creating projects with CRT statically linked, and i DO want to create a dll without it's own copy of the CTR. that was my question. I already had problems with freeing the memory i have allocated in a dll. I have solved them by rewriting an allocator for vector and map.But now i am thinking of this another possibility. As long as the dll's code is executed in the context of calling thread, i thought it could be possible to use the caller's copy of the CRT.. ...Show All

• Smart Device Development Handling events in a multi-form application

  I'm trying to write a .NET CF 2.0 application that behaves a little like the built-in Calendar application, in that the main form has multiple views with very different contents. In fact, in my application the four views are so different that I'd like to implement them as four different forms, so that I can use the Visual Studio designer to layout and script each one separately. This also allows me to completely close the forms I'm not using so that they're not taking up memory. Taking some inspiration from the FormStack sample code, I replaced the usual call to Application.Run() with a custom routine that does: do {     Application.DoEvents(); } while (MainForm != null); ...along with code and event handlers to make sure t ...Show All

• Visual Studio Express Editions Why Is It So Difficult To Save and Load Form Text Boxes?

  I would appreciate any help someone could give me. I have searched this forum endlessly trying to find a way to save 60 or so text boxes on form1 to a file and then later read the information back into the same text boxes. It seems like I have tried every bit of sample code that I can find and nothing works. I have 5 books on VBE and VB5. I am a complete novice at this so please be gentle. Thanks in advance for any ideas/help. Glenn Well... I'll step out. You see, I think your intital approach is not that great and it's going to cause you problems and you will end up building a bi-plane. Why not take it a step at time.

• Game Technologies: DirectX, XNA, XACT, etc. Running builds

  Okay, I am a super newb so don't scoff okay. I just started playing around with XNA beta 2 and I have a small, but hilarious, problem that I can't seem to figure out. I am in the "Your First Game: Microsoft XNA Game Studio Express in 2D" starter section, and I am at the end of step 4. The text tells me to "build and run your game". I built it and it tells me that the build was successful, but I can't find the option to run the game!! Please someone, just tell me how to "Run" my build!!! It's easy enough to miss. Looking at your toolbar under the file menu, you'll see a little green arrow. Clicking that will "run" your game. You can also hit the "F5" key to get the same result. Congrat ...Show All
