Windows Forms How do I Create a MenuStrip at run-time?
I want to create a Menu strip on the form when it loads. Since this is a small app, I didn't want to drop a Dialog onto the form. I thought I could do it like an Open Dialog but I can't get the correct code. What Am I doing wrong using System ; using System . Collections . Generic ; using System . ComponentModel ; using System . Data ; using System . Drawing ; using System . Text ; using System . Windows .

Smart Device Development Widcomm Driver Using Iomega Dongle Not Supported When Running ActiveSync
I am running, as it appears, an unsupported dongle in the bluetooth stack - an Iomega GBU211 I can get a handshake between the computer and the device using the Widcomm software, as both pair using a serial port connection. The device, a T-Mobile Dash , then should be running on ActiveSync but since the connection was made using the Widcomm software the device can't sync, even though both the computer and the device appear to be connected. Hopefully this makes sense - any ideas This forum is smart device development related. Since your question is not related to smart device development, it's off topic here.

Visual Studio Express Editions BindingManagerBase Position_Changed Problem
Hey Everyone, I have a program that has several textboxes bound to 1 dataset which contains only one table. When the form loads, the data is displayed in the textboxes allowing the user to add, edit, delete, etc., as well as navigate through previously entered records. However, when trying to navigate through the records, it doesn't do anything. The recordCountLabel, which keeps track of the record number that is displayed, changes, but the first record stays on the screen. Here is a little of my code. Protected Enum Record RecordNum DDate Shift ATO Vehicle End Enum Private Sub Form_Load( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase .Load 'Loads data into the 'TripSheetI ...Show All
.NET Development We're not supposed to use List<T> ? ( List )
I installed FxCop and had it analyze my application. In several spots, it says: "Do not expose List<T> in object models. Use Collection<T>, ReadOnlyCollection<T> or KeyedCollection<K,V> instead. List<T> is meant to be used from implementation, not in object model API. List<T> is optimized for performance at the cost of long term versioning. For example, if you return List<T> to the client code, you will not ever be able to receive notifications when client code modifies the collection." I'm a bit weak in my OO.. so I'm not sure what "expose" really means in this context. Is this saying to not use List<T> ...Show All
