I need to know the proper way, or maybe I should say, the different ways to call another form from a parent or preceding form. I am currently using ex: formname.showdialog() to call my next form, but I am uncertain if I should be using that in every situation. [code] Whats the difference between these different methods? (ex: .showdialog() , .show() )I tried both of these to open a temporary form to retrieve a persons name from a database, so as the users progresses through my training program they can keep track of their scores.But, I also call other forms as I branch through my program, from the main page, to a secondary page, to a testing page, to a results page and then back to the secondary page

View 1 RepliesI have written a set of functions in VB 9 that I want to be able to call from several different programs (also VB 9). I compiled the functions into a dll and I am attempting to call the functions but to no avail. Within the dll project, the class is Public as are the Functions.Within the exe project, I have declared the dll functions using Declare statements of the following form:Public Declare Auto Function FunctionName Lib "DllName.dll" ( ) As String.I thought that this was all that is required. It builds fine but when I attempt to call the dll functions, no entry point is found.

View 1 RepliesI am the author of the MAPM arbitrary precision math library. This is a library which allows the user to make any calculation to any desired precision level. The library is written in straight ANSI C.
On many occasions, I get an email on how to use the library from a VB.NET / Visual Basic application. I have very little basic experience, and I don't know what to tell them. I would really like to tell them how to proceed to call MAPM from a basic application.
Let's assume they can compile the library with a C compiler and create a DLL.

I build two programs, 1 - bootstrap and 1 - mainprogram
now, mainprogram has 2 constructors, the default and the one which i defined and it accepts an integer the default constructor checks the variable named iscalled a type of integer to have a value of 1 or zero, if its zero then it should shows a message saying "Improper initialization" then exits..
What I mean here is, mainprogram should only run if its called by the bootstrap program.
I am struggling with this program which uses emgucv(an opencv wrapper for .net) for about 2 weeks. The problem is unfortunately not programming, but setting up emgucv in such a way that it works. I didn't manage to do so for vb.net so I tried doing it for ironpython(because I know python too). Emgucv seems to work perfectly when using ironpython, so I created a function that takes an image as an argument and analyses it in the way I want, returning another image with the results in it. The problem is I want to call this function, giving it the image argument(it could be a string containing the path) from within VB.net and become another string containing the result image as return. I later plan to package that project in a setup so I can redistribute it.
View 1 RepliesI'm looking for a more elegant way to work around a problem I have
Code:
Private Sub MnuCheckForUpdates_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MnuCheckForUpdates.Click
Dim startInfo As New ProcessStartInfo(mStartUpPath & "" & "Updater.exe")
Process.Start(startInfo)
End Sub
As you can see I�m calling my updater program, but I want some code to run only after the Updater has closed.My work around was to:
A - Initially load the updater.
B � Start a time
C � Check if the updater is still running.
D � If its not call the routine in the timer event.
But this is not elegant is there another way around this, I can call events in the updater but I don�t think I can join them in someway to ProcessStartInfo Class .
