If Compile A VB6 App On Win7 - ADODB.Connection Errors With "Class Does Not Support Automation Or Does Not Support Expected Interface"
Apr 28, 2011I compiled some VB6 code on my Win7 x64 machine and the result .exe will not run correctly on any other machine. VB6 code is just a new template .exe file with one button, a reference to "Microsoft ActiveX Data Objects 2.6 Library" and the following code in the button press event: Dim db Set db = New ADODB.Connection It runs correctly on my machine, but no others (even other Win7 x64 machines) (Update: I found TWO other users where it runs and one of them is Jeff Atwood!, but most machines have the same problem)

Stuck Understanding OO Concepts?
Dec 14, 2010so i have a class called FOOTBALL,then another 3 classes/forms that inherit FOOTBALL, they control score (SCOREBOX), possession (POSSBOX), and quarter (QUARTERBOX).the FOOTBALL class has 4 variables, "score" (array of 2 ints), "teams" (array of 2 strings), "possession" (boolean), and "quarter" (int)after that i have another form called MAINBOX, which creates new instances of the 3 classes (SCOREBOX, POSSBOX, and QUARTERBOX) (like this: private scoring = new SCOREBOX)... however they all technically create their own FOOTBALL classes, so I cannot connect them.
View 4 Replies[2008] Mixing Different Concepts Together?
Mar 15, 2009This is my first post as I don't like to ask questions without making sure I've exhausted all other means. I'm new to VB2008 and programming in general but I'm learning. I want to do several simple tasks. Doing each separately is easy but when I put them together I don't know what to do. For one thing to work all the code must be changed and everything else doesn't work.
1. Plot a graph of data from a DAQ. I can do this by using a Timer1_tick method and displaying the data on the linegraph as long as the timer is turned on. I've decided to stick with this method of acquisition. I want to acquire data for long periods of time (perhaps 3 hours) so a timer is pretty good. No problems here.
2. Apply a filter to remove noise from the plot dynamically as the data comes in so that I get a smooth curve instead of a jagged graph. I know I can do this with for loops if I'm using an array. But how do I do it since I'm using a timer? Here the problem begins.
3. Log every piece of the filtered data that the timer is getting to be exported to a CSV file. I learned how to do this with do loops but not with a timer or array. But I really need to use the timer this time.
4. Acquire statistics for the data like maximum value, minimum value, and average value dynamically as the data changes. I know how to do this with an array of data after all the data is acquired. But How do I do this with a timer while the data is still being collected?
5. Monitor the data coming in to execute an alarm (Or event, like stopping the acquisition) when the data coming in has plateaued and is constant (eg: The voltage I'm monitoring starts to become constant and becomes one constant value) - Ok I don't know anything about this.
6. Execute a mathematical operation on the data that has been acquired (post acquisition) like finding gradients and such. Basically this means "How do I now manipulate the data I have and where is this data stored?"
Here's my starting code that gathers data with a timer. How do I work from here?:
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As
System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Timer1.Enabled = False

View 1 RepliesGame, Unable To Grasp Certain Concepts?
Jul 1, 2010Ok, I've researched for hours about classes, creating classes, creating obj's of that class, but every tutorial I've seen has either talking about things that are different from what I'm doing, or they were written with the assumption that I understand X or Y. What I want seems simple enough but it's just not clicking. Here's what I'm trying to accomplish:
1. Player chooses from a list of characters
2. That character has specific attributes (power level, experience points, ect..)
3. When entering the combat page, the specific attributes are displayed in text boxes
with respective labels.
4. When battle is over, experience points are handed out and saved in player class.
It's probably laughable to some how simple this is but I'm really struggling with it.

Apparently Visual Basic attempts to convert any floating-point numeric expression to Long. OK, this part is clear.

Add Some Scripting Support To .NET-application
Jun 21, 2010I would like to add some scripting support to my .NET-application (I usually code in VB.NET). Since VisualStudio 2008 won't let me use VSA to get scripting support, and the Windows ScriptControl crashes in 64-bit mode, I have been looking for an alternative solution to my problem.I would really like to be able to code the scripts in VBScript or VB.NET, because of the simple syntax.Would it be possible to implement some kind of sandbox inside my application to make it run a VB.NET application inside itself? Or is there any simpler way of getting scripting support?
View 2 RepliesAdd Support For MTP Based Devices?
Apr 3, 2007I'm writing a media management tool and want to add support for MTP based devices.I've been reading through the SDK docs and with the help of some C# examples have managed to make a start on getting some VB code working.
I've come across a few anomolies that I hope someone can help me with!In the examples IPortableDeviceManager.GetDevice appears in C# to receive a string array. But in VB.NET it appears to only receive a string. I have a similar issue with IPortableDeviceManager.GetDeviceFriendlyName which according to the C# samples appears to receive a char array, whereas in VB.NET it is accepting a UShort.

Does VisualBasic Support WSDL2.0
Aug 24, 2009I'm developing a new SOA system right now, and would like to use WSDL2.0, but I heard some clients are still connect using VisualBasic and WSDL1.1 (mostly from excel sheets and stuff). So I was wondering if VisualBasic also supports WSDL2.0, or if it's all 1.1
I know WSDL2.0 will work with C#,Java,and most other typical application programming languages, and these languages will be used by most of our clients, but I don't want to alienate our VB users, so that's why I'm asking.
