May 14, 2012

I have a checkbox list which is filled with entries from my database on page load. I need to update an entry in my database when a item is checked and when an item is unchecked. Right now I am doing the following:

</asp:CheckBoxList>

And the function:

The error is: "Object reference not set to an instance of an object." Is there a better way to check if a list item is checked or unchecked?

.net - Unchecked Integer Addition In .Net?

Mar 8, 2010

I have a project where I want to have checked arithmetic by default, except for one performance sensitive spot. Unfortunately, VB.Net doesn't have an 'unchecked' block.Ideally the framework would have some sort of integer type with explicitly unchecked arithmetic, but I didn't find anything like that. I did find that expression trees have binary expressions for unchecked operations, but the delegate overhead cancels out the unchecked advantage (and then some).

Currently I'm converting the inputs to UInt64/Int64 before doing the arithmetic, then converting back (with a bitwise And to ensure in-range). It's about 50% slower than unchecked arithmetic (according to profiling).

Moving the arithmetic-sensitive part to a project with unchecked arithmetic might work, but it seems like overkill to give it an assembly all to itself.

Setting Checkboxes To An Unchecked State?

May 30, 2011

I am using VB Stuido 2008, Net Framework 3.5.I have one Checkbox to Identify the record as Inactive if checked. When I load the form the checkbox is alway unchecked, which is what i want. However, when I go to add a new record the checkbox, not the text for the checkbox is always shaded green, not a checkmark. The checkbox then reacts as if it is checked. This makes it necessary to uncheck the checkbox or else all my record react as if checked.

in the table defintions I have set the default binding value to ((o)) which = unchecked. Iafter setting the default value to ((0)) I deleted the checkbox from my form and then replaced. Not I still get the checkbox shaded which reacts as if Checked.

VS 2008 CheckBox Always Believes It Is Unchecked?

Oct 3, 2010

I have a very stubborn check box . Let me tell you its story :There is Form1 with a button leading to Form2 . On Form2 there is located that stubborn check box I was telling you about . That check box has code in its CheckedChange event and accordingly to its Checked condition , it enables or disables some text boxes .Well , the first time Form2 is shown , that check box works fine : when I check it it enambles the text boxes and when I uncheck it , it disables those text boxes .Then , I press the button to return to Form1 . If needed , the code in the button is :Form1.ShowMe.CloseMy adventure starts when I show again Form2 ... This time the check box is acting weirdly . No matter if I check it or I uncheck it , it always disables the text boxes , as if it is constantly unchecked ! I can see it changing its checked state whenever I click on it , but it always runs the code to disable the text boxes.

I even used some break points in the code and found out that indeed it is the code that disables the text boxes that is called every time , no matter if the check box is checked or unchecked .I don't thing this has anything to do with the fact that this event is called by all the 4 check boxes on the form . After all , it is always the 1st check box that causes the problem (I can see it when moving the cursor over the genericindex variable) .

CheckBox Unchecked - Clear Contents In RichTextBox

I am using the following code for a checkbox, if checked it should print the text defined, unchceked, it clears the items in the ricktextbox. My problem is it prints fine (lets say it prints two lines) as defined, when I uncheck, it clears the text in rich text box, but when I check again, the text appears in the richtext box, but displayed from 4th line. I need to restart from the beginning/ or at least from the next available line. I cant use clear() since it erase all the contents as i have another 3 checkbox items placed.
