• Visual Basic Listbox

  Hi all, I would like to know about how can I bind data from a PD class to several textboxes accordingly whenever i select on the particular value displayed in the Listbox. Assuming that all the text box controlls have their DataBindings "Text" property set to the name of your BindingSource (in this example myBS) you could do this: Private Sub ListBox1_SelectedIndexChanged( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged Dim foundIndex As Integer = myBS.Find( "MySearchColumn" , ListBox1.SelectedValue) myBS.Position = foundIndex End Sub where "MySearchColumn" is the name of the column in the BindingSource th ...Show All

• Smart Device Development WM 6.0 - Better handling for managed to unmanaged?

  I was just wondering if 6.0 kept the same model for handling unmanaged to managed code or if anything better had been thought up. Anyone know Hi JR, There are no plans to change the native->managed features in any upcoming release of NetCF.  Our model is fairly consistent with the desktop framework--the biggest difference is that we don't support native hosting, so all calls have to originate from managed code.  I'd be very interested to hear what features you would like to see to added or improved. Thanks, Ryan Chapman .NET Compact Framework ...Show All

I am attempting to pick one weight out of a group of three, the three have the same ResidentID and different dates in the table variable @WeightReportRaw.

• Software Development for Windows Vista Why doesn't ActivityTrackingRecord.ContextGuid match any context guids in the rootactivity?

  In my system, I need to track additional information about a workflow. I implemented a custom tracking service so when the a new activity tracking record is sent, I can inspect the activity type and determine what additional information can be tracked. My problem is finding the correct activity instance associated with the tracking record. When I try to find the instance based on the root activity, the qualified name, and context guid, I get nothing. The reason for this is the ContextGuid passed into the ActivityTrackingRecord does not match any guids returned from the Activity.ActivityContextGuid dependency property. I am using a simple sequential workflow. Any idea why this is Yes, that's correct (I ...Show All
