I need to build an application that could run code in private function, based on what user has selected using combobox. For example combo box has three values, One, Two, Three. If user selects one, code written under Private Function One() runs and vise versa.

I know it has something to do with the fact that the first function is shared and the second function should probably be Public as well but I don't fully understand the reason behind it. Probably not relevant but I'm calling the web method from some javascript.

The project requires a form that has textboxes for a students name and the amount of books they have read, and a label where the points they have earned for their reading is displayed. Also a seperate form with About information and yet another seperate form for summary information.
View 1 Repliesin VB.NET it is possible to omit parentheses when you call a parameterless function. However this can be very confusing because developers could think that a statement is accessing a property instead of a method. this could result in a performance drop if you are calling the method again and again instead of storing the result in a temp variable.is there an option in VS2008 or a compiler option to force parentheses on statements that are calling a method? and if so, would it be also possible that VS will insert missing parentheses automatically if you "format document".

If I have two threads both calling a normal function at the same that appends strings, sometime the output string is a combination from both threads as the function had not finished executing the code before it was called again... Would a shared function wait to finish first?
View 9 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.

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?

Is there any specific way of calling the form of another application.My main project is a WPF application.From that it is calling another application is Vb.NET.. This is done by creating a process and then calling the exe.
Dim fp1 As New Process()
fp1.StartInfo = New ProcessStartInfo("Location of the exe")
fp1.Start()
Now the problem which I am facing is that from that exe I need to call a specific form in the WPF application.
I have a vb6 project in which I use a dll library to do some tasks. For that, I add a module which declares all functions of that library such as:Declare Function myFunction Lib "abcdapi.dll" (ByVal hVar1 As Long, ByVal hVar2 As Long) As Long When I call this function (and many other similar) I'm able to do the work and correct Long pointer is returned. But when I try to do the same thing by VB.net (by importing the same library using dllimport and calling the same function), I get no result. although it does return some pointer but that doesn't produce correct result.

I have a question regarding VB.Net and Object-oriented programming.
I have a solution consisting of two projects.
One project is dedicated to the logic of the application, and one is only to show the Winforms form, and to reflect changes made in the logics project. In other words, when an array filled with various attributes residing in the logics project gets changed, then these changes should be reflected on the form (not that strange in theory).
Here comes the - for me - really tricky part:
I have created user controls, and these are residing in the forms project and placed on the aplication's form. When I click on any one of them, their respective onclick sub gets called okey, but how can I send a message to the logics project from their onclick subs? Basically, I'm not sure on what should be private or not, or possibly how to call the other project correctly. In any case, I can't get it to work.
To sum up: What I need is a line of code calling a class in another project, and someone telling me what should be private, static etc.
1) Is it possible to access the Excel mathematical functions without actually opening Excel?
I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?
2) Does anyone know of a MS link or area that gives instruction on "how to" use every function of every Windows DLL at all?
Or for all those that Microsoft have chosen to document online at least.
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?
