Why isn't there a numberBox Windows Form control like a
textbox control but for numeric (float) input? There
doesn't seem to be any easy or visual solution to this
VERY SIMPLE ISSUE in either version of Visual Studio. I
simply wanted to create a Windows app where a user could
enter miles or kilometers, gallons or liters, and see the
other in the adjacent box. The form was easy but the
textbox control would not let me cast any number of...

Dear All,
We are developing applications in ASP.Net...in one of our
applications we would like to use a GridControl...we have tried to use
a Server-Side Grid control but found the speed to be an issue...also
our clients would like to use a lot of client side events like
sorting, searching text, save each row on tab out of a row, use the
auto correct feature...
after intial r&d we feel that using a Grid Control in WinForms would

Hi all,
who can give me an answer on this question: how to validate controls on
WinForm? So clicking on AceptButton does not return control from WinForm to
program until all controls have proper values.
TIA,

I know how to use the ErrorProvider in my winforms..or do I? I validate
the values and set the ErrorProvider in the validating event. If not
valid, I set e.Cancel = True. I clear the ErrorProvider in the
validated event.
Is there a way to know if all validated controls pass validation when
the user clicks an OK button? In ASP.Net there's the Page.IsValid
method. Is there something similar in winforms, or do I still have to
write an...

Hi,
In my current project, I need to embed an .NET winform usercontrol in
the aspx page (via <Objecttag). This winform usercontrol has an
event called DoEvent (void DoEvent()). This winform usercontrol will
fire this event upon certain action by the user. I tried to let the
aspx page subscribe to this event via
<script for="winObj1" event="DoEvent()" language="javascript">
window.alert("window control event happen!");

Hello,
I have created a solution which has both a web UI and a winform UI, the
latter is just for administrators. The Web UI (a Web Application Project)
and the winform project both reference the same BLL in a separate assembly,
and I have all three projects in a single solution file for development,
with the two UI's each having a project reference to the BLL assembly. I
created a Setup and Deployment package for the winform app...

Hi,
We're developing a large winform application using VB 2005, and we'd
like to use the MS Enterprise Libraries to handle logging, audits,
error handling, validation, caching, and more. I've found TONS of
material online, but most is either geared around C# or ASP.Net with
very little focusing on winforms and VB. Can someone suggest any
material, whether a book or online resource, that would help us get
this off the ground?

All,
I have a form that has a text box and button - when the button is
pressed the form will close if the correct text is in the text box -
works fine.
However, if the text box is blank I can't reboot a Windows PC which I
want to allow (if I enter the correct text it will reboot). Is there
anything I can check in the form's OnClosing method to see if Windows
is trying to close the form as opposed to a user closing the form?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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,...
