I'm using a 3rd party DLL to access a proprietary Database. It's designed to invoke a function called "CALL_ME_FUNCTION" to make the datarows available to my program. What makes it difficult is the CALL_ME_FUNCTION is in the VB program and therefor, external to the DLL iteself. I've got the CALL_ME_FUNCTION written in my program, but how do you give access of it to the DLL? I've written lots of code that invokes functions inside a external DLL, but this is the first time I've encountered a DLL that needs to run a VB function.

Here is the code I have so far.

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 have an application (app.exe) that has a VB Module in its source code (Module1). The module has a function called Function1. I need to call this function from another application. The module is not marked as public, so adding a reference to app.exe won't work. I'm trying to use reflection (Assembly.LoadFrom()) but unless I'm way off base, the module would have to be a class in order for me to get an instance of it.
Please nobody ask me "what have you tried?" I tried a million different things and let's just say "none of them work." So I'm looking for someone that has specific experience with doing exactly what I'm trying to do. If you don't have that experience, please move on to the next question and ignore mine.

In a program of mine, I have a resource (which is a textfile). This contains also vb.net code, It is resource which is binded to an .exe, with the mainprogram that I have. So the main program calls the resource, and the resource bind to an exe file.
I have this line:
Declare Function GetProcAddress Lib "kernel32" (ByVal handle As IntPtr, ByVal name As String) As IntPtr
In the source.txt and I want to replace this whole line by a string(or word) which calls this line from somewhere else. For example in another source.txt. A textbox is not possible because this is not a vb form, but a .txt-file. Maybe I can create another resource, which IS a vb.net form, call it or something? In this case. I can create a textbox with this line that I gave above, And I can use it by: textbox1.text.

I get this error: Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
Partial Class _Default
Inherits System.Web.UI.Page
<WebMethod()> _

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.

in 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".

I have a midterm project where we must replicate what our teacher has made, it is a convenience store program. I am having trouble calling the functions, he wants us to use these:
PopulateItems => Populate Items listbox based on the category selected
GetItemPrice => Retrieve the price for a given item
GetItemPriceFromPurchases => Retrieve the item price from the purchases list box (optional. You may not need

So far I have the first list box populated when the form loads. However outside of that I do not know where to call the function in order to populate the second list box upon selection of the first.

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?

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.
