Determine Empty Checkbox List

Hello All

I have a ASP.NET 2.0 checkbox list, the problem is when 0 items are checked
I am unable to determine if the list is empty
//Determine Checked Roles
CheckBoxList ckUserRoleList =
gvUserList.Rows[e.RowIndex].FindControl("c kUserRoleList") as CheckBoxList;
StringBuilder oStringBuilder = new StringBuilder() ;
foreach (ListItem li in ckUserRoleList. Items)
{
if (li.Selected == true) {
oStringBuilder. AppendFormat("{ 0},", li.Text);
}
}
if (oStringBuilder .Length != 0)
oStringBuilder. Remove(oStringB uilder.Length - 1, 1);

string[]userRoleList = (oStringBuilder .ToString().Spl it(new char[]
{','}));
/**** Empty Values are NOT Correctly Evaluated ****/

//Add New Roles for Selected User
if (userRoleList.L ength != 0)
{
Roles.AddUserTo Roles(userName, userRoleList);
}

The problem is I want to identify which checkbox item caused the event to fire to perform some routines based upon the value of that individual checkbox. How can I determine this? For example, 5 of the 10 items maybe checked. However, when I uncheck one, I want to perform some code based...

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...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
