View 3 RepliesI've got a class where I pass in a panel reference and in that panel I'm then required to draw multiple other panels that represent my objects. The issue is that when I go to bind dynamically click events to these panels I don't have reference to the Form of which I want to popup on the click event.
The reason for this structure is so that I can redraw my class dynamically and reattach certain events to each object.
Is there any way to do this without moving my classes logic outside of the Assembly or is there any way to attach my click event to a piece of code logic to a sub in my WinForm?

Im using a dataset to display data in a datagrid from a sql server DB. One of the colums I have in my datagrid is "Status" the table adapter sql statment selects certain items based on whether there open or closed e.g "where = Open ". I want to remove this row entirely and instead of displaying open or closed for status column, display the open/ closed results in colour on the datagrid. Im really not sure how to go about this whether i need to do it in the table adapter or some sort of property. I presume i need to write a sql statement and selct the identity of the row where x= open etc , is there a way of assigning a colour in sql statement so it displays on my vb form ?
View 2 RepliesConsider following code:
Dim S1 As String = "a"
'this is the string in a file
Dim StringFromFile As String = "S1=hello"
[code]....
how to assign value to S1?I have declared a string named S1. Now I want to assign new value to S1. The new string value is stored in a file using following format: [variable name][= as separator][string value]. How do I assign the value to S1 after retrieving the string variable name and value that stored in a file?
NOTE:
temp(0) = "S1"
temp(1) = "hello"
It should be noted that the string with the data comes from a file that may change from time to time! When the file changes, I want the variables to change as well.
Further clarification I need a piece of code that when processing a string like this "S1=hello", the code will first find a declared variable (i.e. S1), and then assign the S1 variable with "hello" string. The "=" just acted as separator for variable name and variable value.
UPDATE:
My attempt to use Mathias Lykkegaard Lorenzen's EDIT 2 example but failed with "NullReferenceException" on this line "Field.SetValue(Me, VariableValue)". Please help me fix the problem. Following is my code based on Mathias Lykkegaard Lorenzen's EDIT 2 example:

View 3 RepliesDoes Visual Basic arrays have the possibility to assign values in one line?i.e. No need to have a loop to assign a value for the whole array.for example,
Dim Array1 (1000) As Integer = 478

this means that all values of array1 will be 478 and the other is 852.

I've been making this BlackJack program for a school project
I have 52 image files, labelled from '_1' to '_52' in my resources folder, each number corresponds to a card.
My question is, how do I get a picture box to assign the correct resource according to a variable
So, say I have
"pictDealerCard1" -> picture box which displays the first of the dealers card
DealerCard1 = 37 -> random number generated through INT(RND() * 52)
and resource '_37'

I am experiencing aproblem in my VB.NET App. The salary form is a databound form in my app to a linq data source. There are several text boxes to enter and calculate different salary fields. e.g. Basic Salary, Budgetary Allowance and Adjusted Basic Salary...
all the above three controls are bound to the datasource. now on the Leave events of the Basic Salary and Budgetary Allowance there is a function to calculate Adjusted basic salary.
The problem is i dont see the calculated amount in the adjusted basic salary but i see only the underlying data in the database instead of the programmatically calculated amount.
I want to assign a value programatically to a field in current DataSet which is not bound to any control on the form. I am using the following method but it does not save the value "F" in DB on calling UpdateAll command.
Me.WorkOrderDataSet.Orders.status1Column.DefaultValue = "F"
My update command:
Try
Me.Validate()
Me.OrdersBindingSource.EndEdit()
