Create Your Own Component In VB 2008?
Aug 27, 2009
How do you create your own custom component for vb.net 2008? I want it to simply output to a .dll, not a whole winforms app.
How can I control the component? For example, I want my component to not have a visible design view, I want it to stay below like the stopwatch component and the notifyicon component and such, it is not something to be designed. Then, how do I edit the possible properties a user can control, and make them effect the end result?

My app is a classic vb6 app. I have distilled my problem down to fact that an activeX control can't be registered on Win 2008 64 Bit using Regsvr32 but can be registered on Win 2008 32 bit and on Windows 7, Vista, XP/Pro, Win 2000 etc. The classic vb6 app works well on every Microsoft platform except Win 2008 64 Bit. Some Win 2008 64 Bit systems seem to work and we're not sure why, but many don't. The application fails with 429 error when run and when you try to manually register the activex component using regsvr32, the registration process hangs with this result[code]...

I didnt know if this was the correct location to post this kind of question. My code is in C# however I am using the visualBasic. Interaction. CreateObject to connect to a OCX file. I notice that this works great for a while but if it continues to do its job for lets say a few days then I get and exception... "Can not create an ActiveX component." I am 100% sure that the ocx and dlls are registed correctly to the system.

I am developing a VB2008 application that makes use of the Office Access runtime.I started development on Win7 64-bit & Visa 32-bit machines.The application runs just fine on the machines with VB2008 installed.I have used a number of tools to build the application installation and I am running into the same thing on all target test machines (currently XP Pro).The system fails when the Office Access portion of the code starts to run.Below is the Just-In-Time debug info.
I also notice that .NET 2 is being called.Is it wise to make .Net3x the preferred .Net client?In the application, I have specificed .Net3 (however, it does not look like it is being called).The target test machine (XP Pro) has .Net 2.3 and 4 installed.See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

I am attempting to learn how to develop applications to interact with the Autonomy WorkSite 8.5 server and have found the WorkSite DB Administrators COM Developers Reference Guide, it has helped me somewhat and I can now see the types of objects that I can interface with, however I am stumbling on showing the members of a group. [Code] Can anyone offer any assistance on this problem? I have read on page 21 of the DB Admin COM guide that it mentions to execute iManAdmin - REGSERVER from the command prompt, however this will not work for me with Windows reporting that the file doesn't have a open with program set. I am running Windows 7 64bit.

I have a DLL that utilizes the Redemption Outlook Library. This is included in the DLL's Reference on the Project Properties Tab. This is a DLL that I wrote and one of its newest features is its ability to send an email.This DLL is called by a Click-Once program that has a GUI. When the program called the DLL and at the point of sending the email....I receive the "Cannot create ActiveX Component" error. So, in the Click-Once application, I also referenced the Redemption Outlook Library thinking that would fix the problem but it didn't. The Click-Once app resides on a server with other Click-Once apps. In it's irectory structure the DLL is also present and now....so is the Redemption Outlook Library DLL. I'm all out of ideas. Here is the code that sends the emails below.
Private Sub SendEmailToUser()
Try
Dim Application = CreateObject("Outlook.Application")

I have an error that keeps regenerating when the form is closed and open back up.
1) Windows Form Application (Project: TestProject)
2) Add class in same project:
Public Class Test : Inherits System.Windows.Forms.TextBox
3) Drag and drop into the form within the project (works fine)
4) Close form
5) Re-open form... then error about the class Test in the project not defined
Actual Error: Type 'TestProject.Test' is not defined.
Is there a best way around this besides creating a separate project and putting the 'Test' class in that separate project and referring that separate project in the 'TestProject'?
Modified Added: By the way... i've used Global.TestProject.Test... but then again another error generate with the custom property within the 'Test' class.

I'm my program always fails at the same line:
objUser = GetObject("LDAP://CN=" & strUser & "," & ADPath)
If I reduce the code down to just this:
objUser = GetObject(), I still get this exception:
"Cannot create ActiveX component."
After googling this for about 18 hours, I found that it could be because of a permissions issue. I am a local administrator on the PC, so I believe that takes care of permissions. Secondly, I discovered that the dll file might not be registered. I tried to use the following command to register the dll file I think is being used:
regsvr32 "c:windowssystem32wldap32.dll"
It says the following:
Error - The module "C:windowssystem32wldap32.dll" was loaded but the entry-point DllUnregisterServer was not found. Make sure that "c:windowssystem32wldap32.dll" is a valid DLL or OCX file and then try again.So no matter what I try to do, I keep getting this unhandled exception error that says that it cannot create the activex component. What do I need to do to be able to use this getObject() command? Is the problem with LDAP? What activeX or DLL file is failing if even just running the getObject command gives an exception?

I am getting a run-time error within my VB app:
Run-time error '429': ActiveX component can't create object
I have run this application under WinXP and previous Windows operating system fine, but when I installed my application on Windows Vista I get the above error at run-time.
how I could resolve this error as I believe it is not a programming error as the app works on other Windows OS's fine. Could it be something to do with registering dll's etc.

I am working on a user control. Embedded in my user control is another user control. All of a sudden while programming some simple stuff I get an "out of memory error message". I can no longer load my project (after reboots etc.). I start a new project, copy the control.vb files into a new project folder.. add then add the control to the new project. Ican view the design and the code of the control. When I attempt to drag the control onto another control in the same project I get an error message
"Failed to create component... 'system.outofmemoryexception. Out of memory".

I'm trying to create a small paint component( similar to MSpaint but not the same thing) in vb.net.I have a panel that holds the background image and a picturebox over the panel that I draw on. I'm using graphics to draw shapes and I have my own custom double buffer, meaning that I draw on the picturebox while the mouse ismoving and on mouse up I draw the final image on the buffer image and on paint event the buffer image replaces the picturebox image.also, i have set the form properties to enable double buffering
Me.SetStyle(ControlStyles.ResizeRedraw, True)
Me.SetStyle(ControlStyles.DoubleBuffer, True)
Me.SetStyle(ControlStyles.AllPaintingInWmPaint, True)
Me.UpdateStyles()
my problem is that no matter what i've tried the picture box keeps flickering. as long as the mouse is moving, the paint event keeps getting called and the image flickers like crazy what i need is more ideas(or pseudocode) on how to avoid flickering.
