VS 2010 Changing Checkbox Values?
Mar 25, 2012
I have an array of structs and each struct contains values for the checkboxes. I am trying to display the checkbox values contained within a particular struct.
MyStruct is an array of structs which has a values for the checkboxes
ChkBoxCol is the collection of check boxes for the form.
I am iterating through the collection as follows:
[Code]...
What I am noticing is that if the check boxes are checked in order (checkbox 1, 2, 3, 4...etc) the code works fine and the values are displayed correctly in the form. However, if the check boxes are not checked in order (4, 5, 7...etc) the code does not write the values of the check boxes and instead keeps them blank. I just need to display the values for the check boxes for a specific struct.

I have a form that creates a row of checkboxes depending on the type of analysis the user wants to perform on the incoming file. I need to be able to determine if the checkbox is "checked" but I don't know how to do that when the controls are created at runtime.So right now I have a loop going through all the controls on the form and selecting the appropriate case: for instance chkbox1, combobox1, etc. Now I can access the values of the control by using Me.Controls.Item(chkbox1) but after that the only thing resemebling checked is .Text which wouldn't be accurate. how do you workaround the .Checked property of a checkbox when it is created at runtime?

I have a form in an application that I'm building and in it I have a datagridview that when a user clicks a checkbox on a line in the datagridview and "submits" the data, then the form will insert all of the data on that line (along with the code "Holiday") into a database. Currently if I click in the checkbox on any line other than the first line and put a line break on the "Try" statement, and then fire the submit_onclick event, I'm never reaching that break point but if I click on the checkbox on the first line and submit that data, that works and it behaves at I stated above. Here is the code as it stands currently:
Code:
Private Sub holidaysaveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles holidaysaveButton.Click

I have 50 checkboxes for 50 american states. The user can choose all 50 or only 1( so basically any number he wants). Based on his choice, I want to insert or update the table in sql server 2008. e.g- Color = blue and chk1=check, chk2= check and chk3 = check (chk = checkbox).
Now the user wants to ad 10 more states to this or remove these 3 and add 5 more. so u basically get the idea. the table in database looks like this -ID Color State_id
There is a table called states, so stateid shall come from there. so how do i do a loop insert or update in vb.net?

All variables and Arrays have been declared properly the problem Is when the user enters a new number using a scroll bar
LottoNumber = HScrollBar1.Value
Label2.Text = "Number Selected: " & LottoNumber
The out put of the variable count stays at 1 so the output stays at (Pick # 1 of 6) and doesnt increment at all and does not build the OutPut string
'IF The LottoNumber Location Value is 0 in the Array selectedLotto THEN mark it by making the Loacation Value to 1
If selectedLotto(LottoNumber) = 0 Then

Im trying to check to see if a value of a label changes over time. however I can't seem to get it right.
dim val1 as string
dim val2 as string
private sub form1_load()
dim val1 = label1.text
end sub

problem is it will only check it once after ten seconds when the timer is set to 10 seconds i need to to check it every 10 seconds becuase these values display altitude, and if the server freezes the altitudes dont change. I need to make sure they are updated and not frozen.

I'm writing a program to help me understand 3d points and how computers manipulate them to 2d. Every time I run the conversion routine in my program the value I passed to it get's manipulated even though I use the ByVal key word. Here is the code in process order , tell me if I missed something here ?
[Code]...
There is a status box for me to check one of the values :> This is the flow of what I have put together so far. The problem is once I run the program everytime I press the up key to make a call to the GetPoints method the value in MyPoint is changed to reflect the forumula in the getpoints method. I explicitly used ByVal in my variables on the method call so the values in the variable would not be manipulated. I've changed it many times but I can't seem to get the method to run where it does the conversion without manipulating the values in MyPoint. I've done similar things in visual basic .net 2003 , Now I am using the visual basic .net 2008 express edition. I don't if there is a difference in the two or some unknown bug.

My first time and first post here.I am trying to change specific registry key values (to enable fast user shutdown), but I get an error message when I try this. I will hopefully be implementing a number of the TweakUI functions, but in my own representation.

and I get the following error message:
"The specified RegistryKeyPermissionCheck value is invalid. Parameter name: mode"
(I've changed the Security.AccessControl options but none of them are suitable)

I have a project due tonight and suddenly 2 of my datagridviews are acting funky while the others are fine.
I have 2 tables in an sqlce db. the first is books(id, title, copyright) and the next is publisher(id, name, bookid). I'm writing a vb.net frontend to access the data.
I have data bound datagridviews for both tables. Both have their respective ID columns hidden. The publisher dgv uses a combobox cell style to display the book title in the bookid column. So far so good.
I have suddenly run into a problem where if I have clicked in a cell on the books dgv and then click a cell on another row, the title changes to the id value. The publisher dgv also updates to show the id instead of the title.
It sounds to me like there may be a problem with the booktableadapter or bookbindingsource, but I don't know where to start looking for it. I have a 3rd dgv referencing an unrelated table, and it has no problems. The code for both the working and problematic dgvs are the same (only the control names are different).

I have a grid bound to a datatable. The grid has two boolean fields. What I want to happen is, when the user checks one field (or perhaps I change that field's value in code), I want to automatically uncheck the other field. I tried the following code, and it gives me the results I'm looking for, but only after the user leaves the row. I want it to happen when the user clicks on the cell.

so i have a user form, and i want to uncheck certain checkboxes if some conditions are met, etc. the problem is, i also have instructions that are supposed to take place when the box is clicked, BUT these are done when the actual value is changed, even if no click takes place. how can i get around this? i tried to have some boolean barriers but because of the complexity of my code, theres no logical way of doing it. is there some property i can use to just change the value and not register a click?
