Windows Forms Editor Exception - vb.net

I'm not even sure how to ask this question, but here goes. The design view of my windows forms object now crashes with the following error:
The control DevComponents.DotNetBar.Office2007RibbonForm has thrown an unhandled exception in the designer and has been disabled.
Exception: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Stack trace:
at DevComponents.DotNetBar.Office2007RibbonForm.WindowsMessageStyleChanged(Message&
m)
at
DevComponents.DotNetBar.Office2007RibbonForm.WndProc(Message & m)
When the error page pops up, it is this:
I can't think of anything I did before this happened, which is very frustrating. The last thing I did was this:
Add Button on Ribbon Control
Double-Clicked the button to add code
Realized I forgot to name the button, so removed the event code
clicked back on the form tab and BAM. Error.
I tried the following to fix:
Went back and did an undo on the code (re-added the event for that button). But didn't help.
Edited the Designer.vb file to remove that button entirely. Still didn't help.
I thought about pasting my designer code here... I will if that makes sense, but it is so huge I wasn't sure if that was worthwhile. Maybe the above error makes sense to someone besides me???
**** EDIT: Forgot to mention the application runs fine. Just can't edit the form anymore.

OK. I found it. For some reason the form duplicated the style on the ribbon control. Even though the error didn't seem like that one.
FYI - I just kept commenting out stuff in the designer and then trying to launch the form until the error went away. When I finally got to the ribboncontrol, I saw that there were 2 statements:
'Me.RibbonControl1.Office2007ColorTable = DevComponents.DotNetBar.Rendering.eOffice2007ColorScheme.Silver
and
Me.RibbonControl1.Style = DevComponents.DotNetBar.eDotNetBarStyle.StyleManagerControlled
As you can see, I commented out the first one and everything worked.

Access VBA: How do I make the VBA editor stop auto-filling values?

I already turned off auto-syntax check but this problem still persists. Whenever I try to modify a time, let's say from 08:30:00 AM to 08:30:05 AM, Access sometimes fills in a zero after I backspace to clear the 0. It forces me to have to quickly change the value otherwise it gives me an annoying pop up message saying syntax error....but the editor caused the error, not me!
How do I fix this? Please help me fix this.
This happens when code is running, which forces Access to constantly compile the VBA source code.
Typical example: a form is open that uses the OnTimer Event (has TimerInterval > 0).
To prevent this: Close all forms while editing code (Design view is ok).
If it's not forms, press the "Stop" button in the VBA toolbar (the blue square) to stop all running code.

vbnet 2008 forms.designer.vb undo bug

I'm having this InvalidOperationException
An error occurred creating the form. See Exception.InnerException for
details. The error is: Object reference not set to an instance of an
object.
pointing at this line of code:
Private Sub BeginningBalancesToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BeginningBalancesToolStripMenuItem.Click
inventory.MdiParent = Me <--error here
inventory.Show()
End Sub
EDIT:
Im only using drag and drop for creating controls from the toolbox. The thing here is, everything works fine until I relocated AND decided to return panel_001 to its previous location by pressing ctrl-z in the inventory.vb during design time to revert the change I made. The program runs fine without error prior to that specific panel relocation. I never edited any codes in the designer.vb and in the inventory class. I strongly believe that a piece of code wasn't properly restored at the ctrl-z action in the inventory.Designer.vb. Is this a visual studio bug?
EDIT: I tried creating a new winform and attempted to start fresh by foolishly copying & pasting all the controls and the forms' class and was no good. I assume the problem does not lie under the striked-out line above.
The Winforms designer has a knack for tripping really mystifying design-time exceptions. A side-effect from its strong WYSIWYG design, it will run some event handlers at design-time. Like Paint, making a control look the way it does at runtime. Nice, but that does come with a price. This can easily cause an exception if such an event handler was not written to operate correctly at design time. You are supposed to use the DesignMode property to keep the code safe.
Coming up with a way a Click event handler could run at design-time however requires massive amounts of imagination. That is an event that will not run at design time, the designer uses a layered window that intercepts any mouse clicks, using them for design use instead. Like selecting a control or displaying the design-time context menu.
I have actually seen the Click event of a ToolStripMenuItem run. The designer is not 100% watertight but it happened just once and I was hacking the code pretty hard. Coming up with a way that it could possibly run by using Undo is going to be difficult. Maybe you give it the Ctrl+Z shortcut, don't assume that guess is credible.
The way to deal with incomprehensible black magic like this is to just dismiss it and move on with your life. You just don't stand much of a chance to diagnose it and if you do then there's nothing you can do about it anyway because this isn't your code. Well, other than the need to use DesignMode, that may well be necessary. Not in this case. The only thing you have to watch out for is that such an exception did not destroy the InitializeComponent() method. That can happen too, you notice by controls being missing when you re-open the designer. Very unpleasant, you do need a good backup copy in source control to recover from that lossage.
OK! after giving it a few more tries, I found the answer. After the exception shows, copy exception details to clipboard and then I pasted it on Notepad. It had a lot of texts but the bottom part was the important one:
--insert wall of texts here-- in C:\Users\Ellen\Documents\Visual Studio
2008\Projects\SampleApplication\SampleApplication\Forms\inventory.Designer.vb:line
760 at CabuyaoWaterDist.inventory..ctor() InnerException:
It pointed me out to the specific line in the designer where the ctrl-z did not properly revert one of the label's caption

Excel giving "System Error &H80004005 (-2147467259). Unspecified error" message

Everytime I load up my Excel document, it repeatedly shows up with the message from the title. The two options are OK and Help. help opens Office Help which is useless for anything. Clicking OK displays another message saying "Compile error: Out of memory." with OK and Help buttons. Clicking OK brings up VBEditor with no debug line selected and no macro popped up either for that matter. Eventually, after it repeats that and complains 20 (exaggeration) more times (I think that's due to having a lot of duplicate code for ActiveX controls on each sheet). It highlights the first line (the Sub declaration) of the code below.
Private Sub ComboBox4_Change()
Range("B3") = ActiveSheet.ComboBox4.text
End Sub
Now this is dealing with an ActiveX ComboBox. Opening a file from an earlier date will give no errors. It's like after a certain date, it just refuses to work with it. And get this, it's only happening on one computer. The files are saved on a network drive, which shouldn't be causing an error.
I'm almost 100% certain I found a solution to this issue. It may have caused issues for someone else 4 years ago, but it caused issues for me today and I wanted to contribute my answer for anyone else running into the same problem.
I had enabled an "Additional Control" in the Controls Toolbox for Windows Media Player. I think when it loaded in a video file, it overran the memory. This is when I started panicking (company computer and all) and Googling and came across this and a few other articles without a real, fast fix.
The hunch: Once that video file was attempted to be loaded in RAM memory (because that's how Userforms work) it locked up all the memory Excel would allow before throwing all the errors.
What I tried from other posts in various places: I rebooted a few times (before Googling, even). I tried the Quick Repair of Office from Add/Remove programs, that didn't work. (I'm using Office 2016.)
So, what worked? I had the idea that maybe I could disable all ActiveX from loading in my file, and Googled that. I got: https://support.office.com/en-us/article/enable-or-disable-activex-settings-in-office-files-f1303e08-a3f8-41c5-a17e-b0b8898743ed and proceeded to disable all ActiveX controls in Excel. I closed the file out. Can't recall if I closed Excel but I probably did.
Then I loaded up my file. (ActiveX is totally disabled at this time.) No errors! I went to VBA (ALT + F11), opened my UserForm, and the video I had inserted and could not remove was just... gone. I saved the file. I closed the file.
I opened Excel. I re-enabled ActiveX in the Trust Center. I opened my file. Still, no more video on my UserForm (I didn't need it anyway) and no "Unspecified" (memory) errors! And, I can save again!
I hope this solution persists... if not I've got some "splainin' " to do. So far, I'm designing and using the Userform, and saving the file, with no issues whatsoever. I think it worked!
I believe the problem was that I had a user form with an acrobat reader display control (like an iframe, but for PDFs). I didn't have this reference or control on that specific computer and it freaked out. Not 100% sure, but the problem no longer exists.
I have been having a very similar problem with WindowsMediaPlayer (WMP) ActiveX control that I have in a Form. Some computers with office 2016 are giving this error code (usless the help button), this is the first post I have found about something similar with WMP, and I found it after searching for this error on ActiveX controls...
So my solution was to go to VBA (alt+F11), right clic on form that has the activex control and then remove it witohout exporting.
The big problem is, that for me, this form is the most important part of the application.
I have no mor information, if I find something I'll come back to post feedback.
I encountered this issue when trying to pull data from an access database. The query I was trying to pull from in the database was an all value query (*). Once I added the individual fields, the error went away.
I've got this error, when I create a user form which has no body section(just header). (Using this method for the messages where I don't expect a user response. Like a progress bar.
Probably, any abnormality(*)or inconsistency with the user form causes this problem.
Solution: Changed the height of the user form just a few pixel.
Just a simple trick worked for me
Go to Excel Options
Manage Excel Add-ins
Uncheck all and click ok

Access 2007 "Return without Gosub" after i deleted a button

SO something strange happened, I was cleaning up my database and deleted a button that honestly just closed the current form and opened a different datasheet. now whenever i try to select a field or do anything I get things like The LinkMasterFields property setting has produced this error: 'Return without GoSub' ...i Dont really understand how this could all of a sudden happen
thanks for any input it would be greatly appreciated
Problem Solved, Allthough i did delete the button the error was caused when i didnt delete the click event associated with the button. It is strange i think because i have most certainly deleted buttons before and didnt need to delete there click event scripts and everything still worked fine.

How to break whenever any line of code executes

I have a very strange bug, which I believe is caused by some code we have executing, but I'm not sure where.
We can reproduce it to the point it happens whenever we click Tab, but short of putting a break point at the beginning of every method in the project to find out what is executing.
Is there a way to set visual studio to break whenever anything executes?
For those curious about the problem, every now and then, we have a few Rich Text Boxes that refuse to lose focus. You can't click out of it or tab out of it.
We have no On Validation or On Text Changed events attached to the control, and believe it's an event attached somewhere else to something we just aren't noticing.
You can set a breakpoint in the WndProc method, which will run whenever Tab is pressed.
