System.Runtime.InteropServices.COMException (0x80040154): Class Not Registered?
Sep 1, 2006
I am a *** programmer and cannot make sense of the error message I'm getting. I wrote a program and it runs fine on my development machine and also on other machines with Visual Studio installed. However, when I run it on any other machines, I get the message below.All of my other programs that I write run fine on these other machines; so I know this problem must be due to some control that's unique to this new program. But I can't make much sense of the error report

I have a vb .net application where the user can choose a directory into which an excel file is written. If the user selects a system directory (yes, my users do this, don't ask me why) then a System.Runtime.InteropServices.COMException is thrown at runtime. I am handling this exception telling the user to please select another directory.

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in STUB_CREATOR.exe Additional information: Exception from HRESULT: 0x800A0036 (CTL_E_BADFILEMODE)
This is the line that creates the error
Dim f As New Scripting.FileSystemObject
starter = f.OpenTextFile(stub_path.Text + "" + cpp_file, Scripting.IOMode.ForWriting)
I have just previously opened the file for writing. but however i have closed the textstream with which i was writing into the file.

I'm using a 64 Bit Windows 7 system and trying to use PrintDialog. I know it doesn't work on Windows 7 unless you add this
PrintDialog1.UseEXDialog = True
So I have added that code but then I get this error for the following
Dim result As DialogResult = PrintDialog1.ShowDialog()
And the error:
"An exception of type 'System.Runtime.InteropServices.SEHException' occurred in System.Windows.Forms.dll but was not handled in user code
Additional information: External component has thrown an exception."

So 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.

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.
Error message says: Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

I 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:
Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
Cannot get the file path for type library "00460180-9e5e-11d5-b7c8-b8269041dd57" version 1.3. Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED))Vb7TestApp
The referenced component 'AxDSOFramer' could not be found.
The referenced component 'DSOFramer' could not be found.
All references from the project on the other machine are present so this is not the issue. The form will also not load in design mode. instead I get the class not registered error.

We have a Dell laptop used to run an in-house VB.NET program. It got a virus. We had to wipe the hard drive and reinstall Windows from scratch. We use Windows XP Pro, which is what was installed on it before. But now our VB program won't run. After trying and despairing of getting remote debugging to work, I actually installed Visual Studio 2005 on the machine, just long enough to get information about what was making the program fail. And the failure was most peculiar. It isn't in our code. It's in the VB setup code that loads the main form. And it says, "Error loading form: class not registered."The gory details are given below. Now here's the strange thing. Not every VB.net program fails on this computer. And the program that fails, fails only on this computer; it has run successfully on several other Windows XP systems with .NET Framework 2.0 installed.[code]

I've been given an assignment in school to complete and I've encountered several problems. I'm suppose to design a form for patients to fill in whenever they are not registered in the system. The GUI is done already but now the problem is that I'm "not able" to link the "Next" Button which can found at the bottom right of the 1st page to Patient's Data / Preblock Data tab to the Epidural tab.there is only one page/form done, the rest all falls in the same page/form but just in different tabs only.
