• Parshuram Checking If Date Value Is Null

• Thomas Mayer Irritating Flicker Upon Startup

  I've built a WinForms app in C#. The basic startup screen is similar to that of MS Word, albeit with a gradient blue background. I just added a Splash screen. It runs on a separate thread and simply displays a borderless form at the center of the screen. It fades in, the main screen appears behind it, and it fades out, leaving the main screen. That's all fine. But what's not is that the main screen now has an irritating flicker of sorts when it appears with the Splash screen in front of it. It never used to do this. What's causing this and how can I prevent it from happening Robert Werner http://PocketPollster.com Try double buffering the forms. A bit of a guess and I haven't tried it but this m ...Show All

• Davids Learning Tab control not hilighting selected tab in yellow

  At design time, in VB, my certain form with TabControl looks and behaves fine.  However, at run-time, the yellow hilights that show you which tab you clicked on don't appear.  They also don't appear on mouseover.  What gives   I verified that the hilights do appear if I look at Control Panel -> System. yes, my bad, it's orange. i got an inkling this has to do with "Enable XP visual styles"... The way my program is structured, a C# subroutine calls a VB DLL which blah blah starts a new thread which starts the form where my tab control is. What's missing I've got an orange stripe on the tab with VisualStyles enabled both in my progra ...Show All

• BigGuy Form.Visible maximizes a form object with WindowState set to Normal

  Hello, In debugging the following code the frmChild.WindowState is set to FormWindowState.Maximized directly and immediately after the frmChild.Visible = true; line is executed. Please note frmChild is a System.Windows.Forms.Form object. This behavior is incorrect and indicative of a bug in the manner Form.Visible is implemented. Please suggest a workaround. // BEGIN EXAMPLE CODE frmChild.MdiParent = this ; frmChild.Visible = false ; frmChild.SuspendLayout(); if (openOrientation == 1) { frmChild.WindowState = FormWindowState .Maximized; } else { frmChild.StartPosition = FormStartPosition .Manual; frmChild.Location = new Point (xPos, yPos); frmChild.WindowState = FormWindowState .N ...Show All

• Jorge Martin Strange behavior with Navigation in BindingSource

  Hi, I got a problem. I have a BindingSource, connecting at my database to show me the data in my program, so I added 4 buttons to navigate, and I navigate using MoveFirst(), MoveNext(), MovePrevious and MoveLast, but what I noticed is that sometimes the method don't work as expected, this happens more when I edit some field. I don’t know what is happening but let's say that I have 6 items, so I edit item number 5, everything works fine and my database gets updated, but when I click the button to call the MoveNext() for example the field that is shown is not the right one, it goes to the item number 3 for example, so I need to click at MoveLast, and then everything comes back to normal. If I don't click at MoveLast it simple doesn't work ...Show All
