Declaring Variable Dynamically In .net?
Dec 21, 2011I have started using the builder class to create my connection strings for the sole purpose of making more generic connectivity code. However, I am stumped on this issue. The MS eConnect product apparently expects to receive integrated security=SSPI in its connection string if you want to use integrated security, (vs Integrated Secturity=True). I thought I would just pass "Trusted_Connection"="SSPI" to the builder class.
as it turns out, the item for Integrated Security is boolean and despite what the documentation says, will not give me SSPI in my connection string. Has anybody else found this issue and is there a simple fix for it? as for now, I'll simply strip out the item and replace it in my string.

Public Constant Versus Private Constant?
Aug 13, 2011When building a class library which contains many classes, all classes uses a lot of common constants and functions, what is the best to do:
1- Declare these constants and functions as public in a module.
2- In each class declare constants and functions used by individual class as private.
The first choice is good for easy and fast implementation, but re-using a class in a different project will require importing the module to the other project.The second choice require a lot of copy/paste for code snippet but a class can be re-used in different project easily.

I am currently able to do this:

Forms :: Convert A String Variable To Constant
Feb 6, 2010I am developing an application which initially allows the user to browse and select a save location. The selected path is assigned to a public variable which is used with concatenation to crate folder for saving user input data. How can I change the path string to a constant so the user can run the program again without having to run setup routine unless they want to change the save location?
View 1 RepliesVS 2005 Variable / Constant Name Held In String
Oct 13, 2011suppose I have variables named A1, A2, A3 ... B1, B2, B3 ... Z97, Z98, Z99. I have a certain operation I want to do using each one in turn. I CAN write a line of code for every single variable, but this will get pretty tedious. I'd prefer it if I can make a function that takes the letter and the number as arguments. So, if it gets the arguments "E" and "10" it will perform the operation on variable E10. What is the syntax for this? say a simple operation such as: result = E10 * 3 Is the syntax any different if I use constants instead of variables?

View 4 RepliesLate Binding - Declaring A String Variable And Assigning The Item Property?
Nov 27, 2011I have a problem involving late binding, and I absolutely cannot for the life of me figure out how to fix it. I have spent hours researching the problem to no avail, so I am turning to stackoverflow as a last resort.The problem is pretty much this: I am creating a grocery list application. I have a class named Item which stores the name, price, quantity, and description of an item on the grocery list. I have a module named ListCollection which defines a Collection of Item objects. I have created an Edit form which will automatically display the currently selected ListCollection item properties, but whenever I attempt to fill the text boxes, it tells me that Option Strict disallows late binding. I COULD take the easy route and disable Option Strict, but I'd prefer to figure out what the problem is so I know for future reference.I shall paste pertinent code here. (Late binding error is in EditItem.vb)
[code]...
I have tried declaring a String variable and assigning the Item property to that, and I have also tried grabbing the value directly from the List item (not using the Get function), and neither of these made a difference.

Oct 8, 2009I'm working on VB 2008 and I keep having the same problem when I debug. It keeps telling me "Conversion from string "blah blah" to type 'Double' is not valid." I know that its something to do with the types and possibly ByVals? I have changed around the types many times an I keep coming up with errors while debugging. I currently have no errors on the error list and I am stumped.
What it should do first is read the input from the txtboxes on my form then calculate meal and total cost in the Processing function. then give output in the output sub. Thanks in advance.

Declaring The Public Variables?
Sep 23, 2011I've created a 30 point wizard. Every step gathers between 1 and 3 variables. I've created a module and publicly declared the variables there. At the end of the wizard, one master form opens, gets all the variables, and displays them on one form. At this point calculations are run too which populates more variables. This works fine for one instance of the process.
the user may want to be running two instances of the wizard at once. Obviously, if the previous wizard is part complete and they start a new one, the variables are going to get crossed or replaced by the new wizard.Is there a way for the variables to be declared publicly but used in multiple instances?

When the next sub is called, the variable is null. The data in the variable has been erased as the execution of the prior public sub ended I'm guessing.
