Managing Form's Code In .net?
Sep 24, 2011Whats the best way to organize code responsible for Form's content.In my case, there is a DataGridView and list, next to it, with a few options available (projects, managers, employees, etc...). Choosing any list's element fills DataGrid with proper data from database.Now, GridFill functions + handling of all add/delete/edit buttons of each list element gives quite a code in the Form's source, which bothers me a bit. How to split it then to avoid problems in the future? While googling, I've seen some advices to use partial classes, modules or just classes. Moving all functions relating the Projects, Managers, ... , to own separate class sounds like a nice idea but then comes the question how to pass all necessary data to the class functions.

View 2 RepliesControls Not Return All The Child Controls For The Form?
Apr 15, 2010I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.

Managing Multiple Subroutines?
Feb 25, 2009have been writing code to replace an old Fortran program. The Fortran program had very organized subroutines which could be called from anywhere in the project. Most of these were relatively small and left a small, easily followed main routine. I'm converting over to VB.net and when I write the subroutines they are all on the same form. Wading through 50-100 subroutines on one form is going to be messy.

View 1 Replies.net - Managing Connection To Database In An Asp.net Application?
Mar 17, 2009what would be the best way to manage a connection to a database in asp.net.My application is built using an N-Tier architecture.The DAL consists of static classes with methods such as
Public Shared Sub Delete( _
ByVal connection As MyConnectionClass, _
ByVal contact_id As Integer, _
ByVal contact_timestamp As Date _
[code]....
The point to note here, is that I pass the connection to the DAL from the BLL.Should I create the connections in the MasterPage, store it in an object, then pass it to my business objects as I create them (the thing I'm trying to avoid)Should I create a connection using a static class and calling a method like CreateConnection on it, from the constructor of my business objects (Something I'd like, but I don't want to have a connection per object, I'd like it to be shared for all instances of my objects, but since asp.net is multi-threaded, a static class doesn't make sense to store connections) the solution should also work well in a Windows Forms environment (So no connection storing in session, and retrieving it with a static method in a class, for the current context)?
