• Andrea Lattuada Creating Muli Lingual Applications

  vb.net 2003 I currently maintain two versions of my application. One is in Spanish and the other is English. I am getting ready to add Portuguese. My application has context menus' and error messages, and button names which need to be in a specific language for a particular build. Can I have one project where my menus', text messages, and button names can be toggled between the three languages. I would like to have one project in which I can easily build applications for my three languages. Thanks, There is a standard "pattern" for doing what you want in .NET - it's called "satellite assemblies." The basic principle is that you load your UI strings from an external assembly based on the current loca ...Show All

• Fata1Attack Automatic Namespace generation in VB

  I've just finished a dll written in VB. I've never bothered with namespaces much until now, but this is a bit complex, so I've arranged it into sub-folders, with a top-level class, a few sub-classes (and base classes), and other classes that hang off some of the sub-classes. Every class has the same "Namespace Handler" around it. Looks garbage in the object viewer - every class is under the root namespace. When using the object however, it looks fine, i.e. you only see the correct sub-sub-classes hanging off the correct sub-classes, etc. However, one of my colleagues who talks C# had a look at my code, and commented that my namespaces were not declared properly, then we discovered that when coding in C#, the namespace line wer ...Show All

• TobsTec Need help with collision and...

  Need help with collision and optimizing the space of an shape when filling it with a bunch of smaller shapes. I got a shape that loos like this and I need to fill that with as many smaller rectangled shapes that I possibly can. So what I first need to do is figure out how to make it check so that the objects are not colliding with eachother or that they are outside the main shape. Then I need to figure out how to maximize the placement so I don't get a lot of blank space. So it might have to flip the rectangled shapes 90 degrees etc. So... my question is.. how do I detect the collision I guess that could be solved like people do with game collision And my second question is for the auto optimizing.. anyone got a clue where to start thinki ...Show All

  Hi, I am developing a windows service. I need to schedule it, so it executes daily at a specified time. Any help is appreciated.. Thanks.. A windows service either runs or it doesn't. Are you sure you need a service If you only need an application to run at a particular time you could use the built in windows scheduler. If you do indeed have a service, then you can simply have a slow timer which checks the current time, and when it meets your time criteria perform your function. ...Show All
