QUESTION
I'm currently coding a program to monitor certain computers on our network. To this end, I have a Monitor object, that I have made a singleton, to ensure that all functions that communicate with it, get the same data. This object maintains a list of ComputerData objects, and provides the public functions to add, remove, and update these objects.
I've written a quick test harness that gets the instance of the monitor, and then sends a couple of testdata ComputerData objects (passing them using a BYVAL)
However I notice that if I change the testdata ComputerData object, AFTER I have passed it to monitor, that the object stored in Monitors list is also updated. Like it had been passed as BYREF.

Passing that by value means passing a copy of the reference, not a copy of the object. Passing a method parameter by value is exactly the same as assigning one variable to another. If you did this:

I haven't been able to display the image in the picture edit probably because my code isn't correct or there's another solution or recommendation that's best. or there is another way by combining the parent path folder and filename even though the filename is in the subfolder so that it can display the image.

I'm working on a wpf application and in one of the views I have a GroupBox that has som TextBoxes, CheckBoxes ..etc and a search button. under that GroupBox I have a TabControl that has 2 TabItems. Each TabItem shows a different DatGrid that are connected to different databases and the GroupBox above is used to execute a search command from a TextBox and to do filtering using the rest of the elements. One of the databases is huge so I need to prevent the user from executing a search if with less than 2 letters but the user should be able to call everything in the other database.

I am creating a child page by using Master page. I have logo, company name in header part of master page. I need to display in next page(child page of master) after login page. Next page will be showing logo and company name of login user. I pass the logo path and company name from child page to master. Labels are doing well but can't display logo. Can you tell me how can I solve this problem?
here is my master.aspx
...ANSWER
Answered 2021-Nov-26 at 02:19Why not just use the page load event of the master page, and have it check for session.
The master page load event ALWAYS fires when you navagte to a new child page. Thus right after your logon, then if ok, then set session for the correct logo.
Now, in page load event of master, you can check for if NO session, and use your logon logo (or no logo),
So, you could put this in site.master page load event:

In my application, I need a system where some messages shown to the user have a "do not show again" checkbox. In the Settings menu, I want to have a section "dismissed messages" with names of messages and a checkbox by each, so the user can un-dismiss them if needed. If the message is dismissed, the last choice user selected in the message dialog should become a default one.
Additionally, settings should be saved to an XML file - including the message suppression state and the default choice. My current solution is very crude, and I'd like to know if there is a better way.
