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 3 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 want to create a vb.net program to install a .exe package which requires selection. A user must choose a group name from the list . The list should have id number i.e. 1 to 100.

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 .

I just have a simple vb.net website that need to call a Sub that performs a very long task that works with syncing up some directories in the filesystem (details not important).
When I call the method, it eventually times out on the website waiting for the sub routine to complete. However, even though the website times out, the routine eventually completes it's task and all the directories end up as they should.
I want to just prevent the timeout so I'd like to just call the Sub asynchronously. I do not need (or even want) and callback/confirmation that it ran successfully.[code]...
