Can somebody tells me what does "object not registered properly" means when I am trying to include the flash object on my project on vb.net? What are the things I should do in order to solve this one?

I have a application that will prompt the user to enter a serial key in after 30 days...and how do I get the application to know the key is valid?Also i would also like to make a keygen that will work with this program.Where I will enter the company name and generate the key from the Name enter.
View 4 RepliesThis little experiment was a test prompted by a previous thread to learn to work in a graphics object, then paint everything later to a picturebox (later, will be looking at building own custom control for the display), and save out the bitmap to a file on the HD.But weird things happen here. Nothing will display in the picturebox, and the saved bitmap is just a black box.The only partial success I had was replacing: e.Graphics.DrawImage(MyBitmap, 0, 0)
with,
PictureBox1.image = MyBitmap
inside the paint event handler, but that caused infinite recursion of the paint event. But at least I could see parts of the graphic for a fraction of a second before it was wiped clean, every time I clicked the "Go_cmd" button. But what is weird is that this partial success showed that the graphics object was copying successfully over to the bitmap image (because I could briefly see parts of it in the picturebox, but the saved file would still come out black, even though it was based on the same bitmap!The code is as follows.Above the form1 class
Imports System.Drawing.Imaging
The single declaration:
Public MyBitmap As Bitmap
The form_load procedure:[ code].....
The code in the version shown above would not even show a brief moment of the graphics in the picturebox, and the saved .bmp file is just a filled black box.
I have some ActiveX that was written for VB6. They all seem to return Variant types. Ex.

In this case the GetPosition control is returning a robot axis position. It looks to me like the values coming back from the function is not getting converted to object type properly.
I am looking for a code snippet which opens a image, creates a clone of this bitmap in memory disposes this opened image so that all handles are closed.
Usually we can open a bitmap using this[code...]
the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )
Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.
I was wondering if anyone knows of a way to check whether a DLL is registered, or at least point me in the right direction on how to get started

View 9 RepliesSo I copied a project of mine off of a flash drive, and loaded it up into VB 2010. When trying to run the debugger, I got this error after the flash screen:
An error occurred creating the form. See Exception.InnerException for details. The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))I expected it to only be the main form considering that's what it was trying to load, so I just rewrote the main form and set it as the main forum as well, and ended up with the same result.
whenever i try to run my program i keep getting this one error:[IMG]http://i54.tinypic.com/2n8u815.png[/IMG]it works fine in college but on my laptop at home it doesnt seem to work :(does anyone know whats wrong with it and if theres a solution for it?

View 2 RepliesI am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?
In C# I can test for this...

Is there a way to do this in VB.NET? Test for null I mean?

I forgot to mention. I have classes written in C# but I am writing my unit tests in VB.NET.
I am trying this in the unit test...
If myObject.Trigger IsNot Nothing Then

View 2 RepliesI am using Vista Ultimate 64-bit, VS2008 Pro, and an Access DB file. In this situation, and regardless that I have register the components 4 times, the dll's are not registered.
The Microsoft Forums recognized this in 2007 with many entries bemoaning this same problem: MSJet40.dll and MSJetOLEDB40.dll will not work in a 64-bit environment.
The forum had one work-around that many claimed to use to solve the problem: namely to change the IIS Advanced Settings to allow 32-bit apps.
The problem is that can't find a way to make this change, and I don't know enough to understand if this works for non-web programs too.
Can anyone let me know how to make this change, or let me know if there is another solution that will work?

I am replacing a VB6 application with a rewritten counterpart in VB.Net. In the VB6 app there was a 'control' application which presented a form to the user and allowed them to select a 'client' from a drop down list. Selecting a client caused the reading of an ini file which set client-specific parameters, including the program names of several dlls, which were also written in VB6 and registered on the subject machine.
For example, each 'client' had a different letter format, and the letter was written by the selected dll. This made everything late-bound, but there is only one user. Most of all, it made it convenient to continually update individual letters by updating only that dll, and dropping the dll on top of the old one. Thus the (clerical) user had only to be told to save this file to the usual folder. I could have compiled everything together in one exe, making my updates larger and more complex.
In re-doing this in VB.Net, how should I replace this sort of approach?
I could tie everything together in one big project (and compile it to an exe which is the large update I was avoiding). Should I just do that? If I continue with the approach of having my client-specific (.net) dlls compiled separately, does this make sense in the .Net world? How do I call them? Do they need to be registered as they were before? What's the right way to do this and still give me the flexibility I had?
I am trying to play a form, but I get a message saying that a class is not registered. How do I register a class?
I think it has to do with the Attributes section in Properties.

View 2 RepliesI have developed an application in VS 2010 and now need to deploy it accross 10-15 PCs. I am publishing to a server where the other PCs will download it from. Only the PC I developed it on successfully installs the application. The others install it but it will not run. As a test, I installed it from the server on to the PC I developed it on, which worked fine. What may be causing it to install but not run on the other PCs? Also, I tried copying the visual studio solution to another PC and installing it locally but when I try to debug on any other machine, I get errors with the auto-generated code that deals with the controls that appear on my form.
The Errors are:

I have an old VB6 application that I'm moving into VB.Net, I also have a COM assembly that is referenced from the application.I want to be able to run both applications (the old one and the .net one) side by side, the problem is that I made a couple of changes in the signature of the COM assembly for it to work on the .Net application (and these changes aren't compatible with the old app).If I install the old application first, it registers the dll and copies it into System32, when I install the new application it copies the new COM assembly into its application folder (in program files), but when I execute it, it tries to load the old assembly (registered by the old application).
