• Windows Forms Eliminating flicker in transparent controls

  Hello all, I am working on an application that requires transparent controls.  I have used Bob Powells method (http://www.bobpowell.net/transcontrols.htm) and it works just fine. However, it is not possible to use double-buffering.  This is mostly not a problem, but for some controls that I use (e.g. a transparent gauge-type thing drawn with GDI+ that changes frequently) there is&n ...Show All

  I have a class called Playlist . Playlist exposes an ObservableCollection called Entries and also exposes a DependencyProperty called CurrentEntry .

Entries collection. But whenever the value of Playlist . CurrentEntry changes I need to update update the items styles accordingly. What's the best way to do t ...Show All

• SQL Server No grouping?

  Hi to all! To count(something), it is usually required to use a group by function, however, that is not applicable in this case: I would like to select records that have similar values for 'col2' and 'col3', given a certain 'col1', and how many records each 'col1' returns. The following example hopefully makes it clear. The table: Col1 Col2 Col3 ------------------------ s1 A B s1 C D s2 A B s2 C D The result should be: col1 col2 col3 Expr --------------------------------- s2 A B 2 s2 C D 2 I had figured out the not-working-query: SELECT *, count(col1) FROM table as t1 INNER JOIN table as t2 ...Show All

• Visual Basic Storing a form in a dll

  In my project I have four forms. Is there a way to store a form in a dll file instead of storing it in the exe file. I want to be able to call the form to show just like I would normally.

• Game Technologies: DirectX, XNA, XACT, etc. Orthographic Projection using DXUT CModelViewerCamera

  I was wondering if there is an easy way to obtain an orthographic projection with the DXUT camera class CModelViewerCamera I have unsuccesfully tried the following configuration: D3DXVECTOR3 vecEye(-1.0f, -1.0f, -1.0f); D3DXVECTOR3 vecAt (0.0f, 0.0f, 0.0f); g_Camera.SetViewParams( &vecEye, &vecAt ); g_Camera.SetProjParams(45.0f, 1.0, 0.0f, 10.0f); I'm not aware of there being any built in method, but CModelViewerCamera derives from CBaseCamera , so you could conceivably specialize it further and add in orthographic support. If you follow the trail, CModelViewerCamera::Set ...Show All

• Visual Basic Disabling CausesValidation on cancel button in vb 2005 not working

  Hey all, I'm trying to get a cancel button on a form to not raise validation events. Looking it up on msdn it seems simple enough I just set the CausesValidation property on the button to False and it should not fire the validation event. However, it's not working. I've looked at the different ways to change AutoValidate on the form but none of them give me the desired results and all the msdn material I can find leads me to believe that the form should keep it's default of EnablePreventFocusChange and that only the control (cancel button in this case) should I have to change anything. I'm not sure if this is a bug in vb 2005 or if ...Show All

• Windows Forms BindingNavigator - how to emulate 'DefaultValuesNeeded', 'RowValidating', or isNewRow?

  As availabile to DataGridView (DGV), how can one emulate 1.  'DefaultValuesNeeded'   -- want to seed the default values 2. 'RowValidating'   -- Trap errors 3. IsNewRow   -- Determine if its a new row so certain validations can be ignored. JS   My Solution was to hook my own save routine in the toolstrip and also added an event handler to when the add new button was clicked. In the add new button, i updated the text boxes with default values. In the save routine, i was able to run all my validations prior to the update/accept. ...Show All
