I have a problem I've been struggeling with for a full week now, and I'm not able to solve it by myself. I've been googeling, and searching in all kind of forums.I have found lots of "this might work", tried it, but no, no success. If anyone have any clue,I'v got, from an external source, lots of classes and functions written in VB that I need to be able to use from a C++ application. My first though was: no problem, I turn the VB code into a dll, and load it from my C++-program. This was though harder than I ever could imagine. My C++-program is not written in Visual Studio, but for simplicity I started with trying to load my VB dll (written in Visual Studio 2010) from a Visual Studio C++ application. This is my code so far:

I looked at the link with the tutorial, but there is a small problem: there are no such thing as "ActiveX DLL" to choose among all the project types. And yes, I do have Visual Studio 2010 Professional (a trial version, but still).
I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.
View 8 RepliesI want to able to hold a key down while the application is loading and depending on which is being held down a certain form is shown.
For example holding down shift and the opening itunes opens a little dialog allowing you set the library(or something)
I can check whether the shift/Ctrl/Alt are being held down but i'd prefer to use the letters/digits.
Such as hold 1 down to open Form1 and hold 2 down to open form 2.
I have a simple console application which consists of a single executable and a DLL file. My project has a reference to the DLL. My question is how do I ensure the DLL is present in the same directory and prevent the console app from crashing? Although in reality the two files will probably never be separated, I want to make sure someone can diagnose the error without me there.
At first I tried adding File.Exists(PathToDLL) at the beginning of Sub Main(). If the file wasn't found, I was going to display a message and quit the application. But apparently if the DLL is referenced at any point in the code, a System.IO.FileNotFoundException is thrown regardless if the line is executed.
Is there some way to handle this in the executable itself without creating another executable to load that one?

View 1 RepliesI'm using VB.Net, and I have a set of data which I have to able to filter through fairly quickly.Basically, the program is like google sugest, but instead of a drop-down menu, I'm using a listbox. When a user enters a word, I compare the word using LINQ and filter those that contain the user's input. The data are all strings of variable length (from 0 to 200 characters, most on 150 character mark), and I have 240,000+ of this strings and counting- all stored in an XML file.
A colleague of mine told me that loading all of that to memory (using VB.Net's XML serializer plus collections of string/objects) is not practical, and would slow the 'startup' time of the program. I haven't finished building the program yet and I'm having second thoughts about continuing this path.
So, my question is: Should I continue with my current approach on the problem (which is load everything to memory on startup), or is there a better way of solving my dilemma?

View 1 RepliesI have a VB6 project that I'm converting to VB 2008. There is a routine in this project to LoadArrays.By passing the proc name and arrayName I want the info loaded into, I can set up a series of calls at application load and have these arrays available throughout the application (Info is used in many areas to populated controls)This routine makes use of Getrows.Example:arraydef = rs1.GetRows.This will load all fields and records into the array.Is there an equivalent in 2008?
