Tooltip and Errorprovider problem

Hi,

I am writing a program which will be used in Win2000 and
Win98 platform. The program include a Form (called
myForm) which has a TextBox, Tooltip, Errorprovider and a
Button.

Tooltip will be set with TextBox content and Errorprovider
will be set in TextBox Validating event if it is empty.
The Button is actually pop (ShowDialog) itself (myForm).

In Win2000, everything is fine,
but in Win98 or WinMe, there's a problem.

Problem:
I run the program, 1st form appear, I type something on
TextBox (tigger set Tooltip), then click Button to pop a
2nd form and set its Textbox to empty (trigger
Errorprovider check). The 2nd form will lose focus and
1st form will bring to front. As long as I click on the
1st form, the 2nd form will appear up front again.

This problem only happen in Win98/WinMe but not in Win2000.
Can someone give me a hand on this please?

Thanks.

I am using an errorprovider and a datagrid component on a form. I use the errorprovider to display error hints in the grid, in the case the entered data by the user is checked and not found Ok. After the data is corrected, the hint does not disappear ! (the exclamation mark however, does disappear). For Microsoft: If I'm correct, and it is a bug, can it be corrected ?

Hi, I have problem with a C# Win Forms app that uses the ErrorProvider class to provide input validation feedback to the user. On my development workstation (WinXP Pro + Visual Studio .NET 2003), when I run the app by itself or from VS in debug, everything works fine... the ErrorProvider tooltips display correctly, etc. However, on other systems (e.g., Win 2003 Server, or even another PC running XP Pro), after the app enters validation...

Experienced posters, I am trying to owner draw a tooltip. But I notice that alot of the basic controls don't have a tooltiptext property. Is this property one that is similarly given to a control when the ErrorProvider is used? My goal is to draw a image along with the text in the tooltip for labels, pictureboxes and such. Not sure if I need to do hoover, enter or exit for mouse events. Or can I just override/inherit from tooltip...

I have the following issues: 1. I want to make it so that ToolTips never go away once they are shown until the user moves the mouse outside of the control for which the ToolTip is assigned. It seems to me that setting the ToolTip.AutoPopDelay to a large value (e.g., Int32.MaxValue) should acomplish this goal, but it does not. 2. I want to make it so that the ErrorProvider message is always displayed when the mouse is over the...

I have to take this personally now. Tooltips have been flakey since the dawn of .NET, but to still have to put up with a disappearing tooltip in VS 2008 is getting beyond a joke. Tooltips have always done this, so isn't it about time they were fixed? I have a tooltip that I assign to a button control on my form. I hover over the button and up pops the tooltip. I move away and the tooltp fades. I hover again, and back comes the tooltip....

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
