i have a form with a couple of textboxes bound to a collectionbase object.
The code looks like this:
txtName.DataBindings.Add(new Binding("Text", instrumentSet, "Name"));
txtComment.DataBindings.Add(new Binding("Text", instrumentSet, "Comment"));
Maybe I'm looking at things the wrong way but intuitively I'd think that the

I've tried to create 11 textboxes as variables (not actually visible in
the program, not in Windows Form Designer) and have set DataBindings to
the text properties of the TextBoxes BUT according to tests I've run, it
says that the DataBindings exist, but the IsBinding is set to False, and
is ReadOnly (the bindings exist, they just aren't active AND I
can't/don't know how to make them active). Is there any way to allow
these 11 textboxes'...

I am trying to get databindings to work with a property of my control. I
have got it to work fine except if my property is an array. Basically I
have an array that I fill and I want my property "Capacity" to fill in with
the value from that array. So I have a class that will refresh an array
every so often. Then I have many instances of a control and each has a
property "Number". What I want is to have my controls "Capacity" property...

Hi,
I want to use databinding on a property for a class that I have created, but
I can't make it work. Below is a contrived example to illustrate the
problem.
It seems that I can't databind properties that I have created, is there a
way to do this?
Thanks,

This is admitedly vague. But so is my understanding of the problem.
I'm using this chunk of code:
retControl.DataBindings.Add(ctrlBinding.PropertyName,DataSource,BindingField);
This resolves to something like:
Control.DataBindings.Add("Text", SomeDataTable.Rows, "Priority");
The only difference that I can see is that one of the DataSets is

As you know there is a databindings property 'Enabled' for fields in
the gridview.
In the custom binding section I have used the expression:
Eval("myfield"). 'myfield' is a boolean field I have in my database.
This (obviously) leads to all 'False' fields being disabled and 'True'
ones being enabled.
What expression can I used instead of Eval("myfield") for the 'Enabled'

Ok this should be simple.
I made a form, added a combobox (for selecting items to edit, not for updating fields), several textboxes, a few checkboxes etc. On formshow it connects to my database, draws down the existing data, no problem. All the records in the datatable that were the result of a query, I could select from, and the other databound components would display the records contents, no problem..... however.... when i add a new row, the...

Hi everyone,
I've just studio using VS2008 and have a quick question regarding databindings, i'm fairly handy with vb6 so this question really relates to good practice rather than actual coding.
Our backend is SQL 2005 express edition, my application connects to this database fine, it is planned that the database will have approximately 10-20 users.
The application is basically a sales based CMS and I wanted to know if I should simply...

Yes another question about databindings.
All my controls are have databindings and works fine for navigating, adding,
deleting etc.
What I want is when I create a New record have those fields pre-fill with
some value stored in my user.setting so the user doesn't have to re-type
evrything all the time.
Should be so straight forward that I don't get it! The fields are not
getting populated with those values.

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
Here is the code in...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
