View 7 RepliesI've looked at a lot of posts on different forums where others have received the same error. Most say they were not referencing the connectionstring from the web.config file correctly, or they were trying to open the connection before setting the connectionstring. Well, if that were the case for me, then how does it work on two different systems, but not on the third? It works on my development PC and on the development server, but not in the production environment. The difference is the web and DB server are separate physical servers in my production environment and on a single server for development. My setup, error message and code will be listed below.
I can simulate the error on my PC if I rename the connection string in either section of the web.config file (appsettings, connectionstrings) to something else. You will see how I have tested both below.

i have used the autofill method of datagridview, but while i am preparing the system, i have to use different connection string for one datagridview and i think that hardcoding the fill method is the best solution. while at it i have the following as my code:

View 4 RepliesI have 2 datetimepickers. I want to run a select statement between startdate and enddate. When I run the project. I get the error: "The Connection String property has not been initialized." [code]
View 5 RepliesSo I took this from an example. GetInstance() is called from hundred different places in my program, and when I debug, the line "Prog = New Program" keeps getting hit for each of those calls. Which I thought was exactly what should NOT happen.. Or do I have some fundamental misunderstanding?
[Code]....
It seems the "New" sub triggers a number of calls to Program.GetInstance, before the first one completes. This is due to me earlier having lots of shared public objects in this class, which are no longer shared since the class was made singleton. And these objects, when initialized, calls the Program class for reference to other of it's objects.

I have the following problem. This is a simple example of some classes I have (each have dependencies on other classes).

The problem I have is that the assert is always null, even though class1 has been initalized. One condition I do have is that I only want there to be one instance of each class created.

Frm.Show

I have a Form with three radio Buttons.At Design time, all are set to Checked = False When I start to debug, the first is set to Checked = True. I assume that this is done by code that I did not write. Is there some way to have the application start with no Radio Button set to Checked = True?

Public Class Question
Private Shared _field as Integer = CrazyIntegersRepository.GetOne()

And the method GetOne throws an exception... How can we manage that? Is a good practice to rewrite that into a static constructor? When is the GetOne method going to be executed if we leave it there in the inline _field declaration?
I have been given the task of debugging someone else's program. It previously ran flawlessly on a 32-bit Windows XP system, but now we are steadily switching over to 64-bit systems and this program has "spit the bit" so to speak.
This is App.Config.xml
Code:
<configuration>
<appSettings>
[Code] .....
The problem is I don't know my alternatives are. System.Configuration.ConfigurationMananger.AppSettings doesn't work.
I've tracked the problem to the last line Con.Open().
Code:
Public Function get_quotes(ByVal strDBConnection As String) As DataSet
Dim con As SqlConnection = New SqlConnection(strDBConnection)
Dim strQuery As String = "SELECT qmpQuoteID FROM Quotes"
Dim da As New SqlDataAdapter(strQuery, con)
Dim dsQuotes As New DataSet("quotes")
Try
con.Open()
The error is "The ConnectionString property has not been initialized."

The code below will throw an InvalidOperationException: The ConnectionString property has not been initialized. The exception is thrown at the line calling Connection.Open() in the Load method. If I use the try-finally statement instead of the using statement, everything works correctly. Can anyone explain why the exception occurs with the using statement?
