Write Simple CAD Software?

Dec 17, 2011

I was just wondering if there are any examples around the internet on how to develop a simple CAD program.

Would I be better off drawing on the form directly or use a Panel or a PictureBox for that?

Write A Simple Expression-like Class In .NET 2.0?

Jul 7, 2010

I'm currently working in .NET 2.0 Visual Basic. The current project is an Active Directory Wrapper class library within which I have a Searcher(Of T) generic class that I wish to use to search the underlying directory for objects.


In short, I want to offer some kind of Expression feature to my users, unless it is too much work, as this project is not the most important one and I don't have like 2 years to develop it. I think that the better thing I should do is to write something like CustomExpression that could be passed in parameters to some functions or subs.

Simple Read/Write App.config Configuration File

Feb 6, 2010

I have a program with various settings, all stored in the app.config file. Often, I have a need to edit the connection string setting. I cannot do so using the My.Settings.myConnectionStringVariable method, as this is read-only. What I would like to do is have a big text box, and simply load the entire app.config file into it. The user could modify whatever they wanted, click save, and the program would save the new edits to the app.config file, and restart the program. I don't have a huge need to only pull out the connection string, as getting the text for the entire config file would suffice. However, if it is easier to pull out just the connection string from the config file, that would work too.

Write A Simple Game On Which The Player Has To Pursuit Some Figures On The Screen?

Oct 16, 2009

I'm currently trying to write a really simple game on which the player has to pursuit some figures on the screen. Since i'm just writing the prototype version i'm using a Panel wich i redraw 1000 times per second. Now, i want that every level is similar but not the same as past level, so i created a Level Class that contains the game objetcs of Player Class and the Figure Class, wich are the ones that have all the movement subrutines. So, with a Timer, 1000 times per second, i get the input from a joystick, pass it to the player objetc and update the position of the figure object. All this stuff is reported to an internal Panel that every level object has, wich i refresh and then pass it ByVal to the panel that the player actually sees. The problem i have is that after the first level ends, when the second level starts running, i can see the last frame of the fisrt level flashing behind the figures and it makes the game run a bit slower after every level. I tried keeping a copy of the inicial state of exterior panel and use it to clean the one i'm using on the levels but it didn't work...

When one of the textboxes (let's call it XYZ.Text) is bound to the database, it prevents the data from any of the other bound text boxes to enter the database. When the binding for this one text box (XYZ.Text) is removed, then all the other text boxes work fine.
