View 5 RepliesI'm refactoring my VB project into 2 projects, one being a utility library that I want to share with future projects.My solution's layout is like this:[code].....
util is created as a class library, and the member files added into it. I've then added util into the main project's references.However, when I try to call functions in util.vb from my main project files, I get build errors like this:
error BC30451: Name 'LogException' is not declared.
error BC30002: Type 'VarFile' is not defined.
These are defined in util.vb, and it compiled fine when it was part of the main project. The declarations look like this: (I've trimmed out the details)[code].....
I can add util.vb "as link" into the main project and it will solve all the build errors, but that seems to defeat the purpose of refactoring out the class library - I would like to develop this library separately, and not always have to keep track of which file links I haven't added in my main project.
Are there any functions that can be called across the project.I mean we cn use Private Sub ABC() function in the document where it has been declared but is there any way that this could be called from any other form?

View 5 RepliesI am trying to convert a VB.NET project to C#. I am conveting all the forms and classes as required, but I don't know where I need to write the events from ApplicationEvents.vb (I believe its autoGenerated from Properties) Here is the code in my ApplicationEvent.vb file:
[Code]....
What I am trying to do is have a class where the functions of the same name are both instance functions and shared functions.
Public Shared Function Get...(byval xx as xx)
and
Public Function Get...
The Public Function uses a Property xx created in the constructor, whereas the Shared Function has the parameters (byval xx as xx).
As I develop code, I often want to unit test some of the building blocks of a class even if they are normally private. If my unit tests are inside the project, I can use "Friend" to accomplish this and still keep the functions private for normal use. But I would rather move my NUnit tests into their own separate project(s). How do I achieve the effe vb.net 2005?

I got a panel that i am adding labels to. I have autoscroll enabled on it so when they fill the viewable space it scrolls. but i need to put the labels to the left unviewable space(when left scroll is already at 0) The label is placed but i dont get the scroll bars and i cant force it to scroll to a - value.
Is this even possible? Same thing with UP.
Or is the Scroll only limited to Bottom and Right?
I have a question. I've got a main application let call that main. And i had some problems with my database and such so i started a whole new project just to fix my databaseproblems. I'll call this project database. Now database works the way i want it to when i run it by itself. Now i inserted all of the files into main hoping i would work there aswell. Ofcourse i had to make some changes because of the namedifference. When i run i don't get any errors but when i try my validation there are some errors there. Main is project which has a mdiparentform and several childs. I'm thinking this in some way causes the problem because when i insert the database project into another (no mdiparent having) project it works just fine.
I hope someone can make sense of this and help me out. Because i tried everything. I copy the code from database to main, I retyped it myself, I even started with an empty form so that I had to create the dataset and everything all over again.
How can I add a form from one project into a new project, I dont want all the code just the form layout.My form has alot of textboxes and labels and I dont want to have to recreate it.

I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?

While converting types, I have found myself using both VB functions and BCL Convert.To* methods.
E.g.)
Cstr() vs. Convert.ToString()
CInt() vs. Convert.ToInt32()
CDbl() vs. Convert.ToInt64()
etc...
Are there any subtle differences that should be noted?
Is there a way to see exactly what the functions are doing. What i mean is there a way to see the class? I know what it does, i just want to know the code.
For example the function: Membership.FindUsersByName()

View 5 RepliesFor reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.
View 2 RepliesI'm redoing a program for my company and my boss wanted me to created the entire thing through functions...
For the task I wanted to know is it possible to have functions within functions?
Sort of like in C where we would have nested structures?
Its a FILE I/O, with robot commands, moves and verifications....
So I would find the line in an excel spreadsheet where it moves, the coordinate, put it into an array.
Take the actual results store them into a two dimensional array...etc, etc....
Another function would eventually compare the results with the moves, and within a tolerance.
