Loss Of 3d Look In .Net Forms?

Sep 15, 2010

I had a large application that I needed to develop into two separate applications with different customer needs. I created a new VB.Net application and copied/imported all the forms and classes into the new application. The new application works but, for some reason all the forms have lost their 3d look, all the textboxes have a flat look now in the new application. It is as if I have lost a setting somewhere that controls the 3d look of the controls. I have checked the properties of each control and they still have the 3d option selected, and cannot see what else could be changed to get the 3d look back.

System.IO. FileInfo Performance Loss?

Mar 9, 2009

I'm having bizarre performance results of the methods in FileInfo class.I'm using 5 methods of the FileInfo class in the Paint event.The datagridview is bound to the dataset.First the application searches files in the RecursiveSearch. When rows are added to the dataset the Paint event is fired and the rows displayed are filled with extra information from the FileInfo class . In this case the performance is very good. If I remove the DoEvents() from the RecursiveSearch the 5 methods of the FileInfo class become very slow (about 0.25sec for each line of code)!When the search ends, the user can scroll down to see the other files listed.At this point the Paint is again fired. This time the 5 methods of the FileInfo class are again very slow!

Private Sub RecursiveSearch(ByVal sPath As String, ByVal strPattern As String) System.Windows.Forms.Application.DoEvents() Try Dim strFolders() As String = System.IO.Directory.GetDirectories(sPath) Dim strFiles() As String = System.IO.Directory.GetFiles(sPath,

VS2010 SP1 And SSMS Intellisense Loss

Sep 30, 2011

how many of you out there in the VB.NET community have installed VS2010 SP1 and are experiencing this issue with the loss of intellisense in SQL Server 2008 R2?I'm holding off installing SP1 because I kind of like the intellisense thingy (though RedGate's SQLPrompt 5 is way better - have it at home).So is this pee-ing you off, have you explored workarounds, tries the hotfixes (that apparently don't work for many setups)?url...Please note that even though Cumulative Update 9 (CU9) was released the month there are still people it does not work for..including a coworker using a similar setup as mine (Win7 Pro, x32) This is a disaster and embarassment for MS IMO

SQLServer To DataAdapter To DataGridView Causing Memory Loss?

Aug 26, 2010

I have an application putting new data into a database so I want to use a DataGridView to display the data. I have a timer triggering every 5 seconds and running this UpdateGridFromDatabase() routine every cycle.
It works, but I can see my application memory usage going up by 10kB every 5 seconds until my computer with 6GB of RAm & 64 bit Windows 7 grinds to a halt! Can anyone see at a glance what I am doing wrong? I am trying to open & close everything as necessary. I have also dimmed two variables outside - I had then inside previously and it didn't make any difference.

Determine If An Event Has Been Attached To Yet?

Jun 18, 2009

I have two objects - one that contains some code with will fire an event, and one that contains the handler for that event. I can't "AddHandler" in the Load of the first object,because an instance of the second object doesn't exist yet. When I raise my event, I want to check to see if a copy of object2 has been instantiated (easy to do), and if a handler has been attached to the event yet (not sure how to do this).I'm also open to another recommendation about how to do this instead. If I do my AddHandler in Object1.Load, and Object2 doesn't exist yet, then it will never handle my event, even if I create it later.Right now, in the code that fires the event, I've just resorted to doing a RemoveHandler and then an AddHandler every single time the event is raised, and then I know I'll attach when the object finally exists, but I know this is a crappy method.
