Net Framework 3.5 Error
Cortney Ruic
When you attempt to run a .NET Framework application, you may receive the "This application could not be started" error message. When this error is caused by an installed version of .NET Framework not being detected, or by .NET Framework being corrupted, use this article to try to solve that problem.
If you still can't run the application after completing all the steps in this article, then the issue may be caused by some other reason, like a corrupted file system, missing dependencies, or a problem with the application. In that case, you can try contacting the app publisher or post a question to Microsoft Support Community or Microsoft Q&A for more help.
The .NET Framework Repair Tools displays a dialog box shown in the following figure to indicate that changes are complete. Leave the dialog box open while you to try rerun your application. This should succeed if the .NET Framework Repair Tool has identified and corrected a corrupted .NET Framework installation.
If you selected the Next button, the .NET Framework Repair Tool displays a dialog box like the following. Select the Finish button to send diagnostic information to Microsoft.
In some cases, you may see a dialog box like the following, which asks you to install .NET Framework 3.5. Select Download and install this feature to install .NET Framework 3.5, then launch the application again.
I installed Affinity Design yesterday and I got it installed. However, every time I try to open Affinty, the attached error message pops up and tells me that I need to download the version of .NET Framework in order to start the program. I followed the link and downloaded it, and I kept getting the same message. I restarted my computer, 'Installed as an Administrator' and nothing seems to work. I have even un-and re-installed it and there's been no progress. Any ideas would be much appreciated.
I installed Dot Net Core 7 but the error still persists. Here is the list of applications installed on the machine. The build is clean and has only Rhino8 installed.

Also while installing Rhino 8 referred (Automating installation Rhino 8 for Windows: Scripted Install [McNeel Wiki]) but did not find any command line parameter to use 4.8.
Also on another machine where Rhino7 is installed, both co-exists. Rhino7 launch without error but Rhino8 has error.
Nearly every time I override the Handle Error.vi method, I end up breaking the stop mechanism on accident. I usually forget to put in case exceptions for 43 and 1608. I get that you want the ability for errors to stop an actor, but using errors as a stopping mechanism forces every single child compensate for that. That seems like a lot of extra cases when all I wanted to do was handle one code then let the parent handle the rest. Why tightly couple errors and the stopping mechanism?
The dissonance for me might stem from how I tend to use LVOOP. I tend to send up the framework in the parent such that the children only have to deal with specific implementation and need to have very little knowledge of the framework. Usually I make it hard for the child to accidentally interrupt this framework.
As a completely ignorant beginner: I guess I'm wondering why Stop wasn't an Actor Class boolean variable. You would set it using a method. This method could be called in the Stop Message Do and possibly Handle Error if the developer chose. The actor core would just read that boolean at the end of each while loop iteration.
Now I'm going to stop yelling at the gods and digress. I do like the framework a lot. In the end, I was hoping to get some knowledge from this rant (either how people work with the handle error, or why it was done this way). Seems like ever time I alter/fight a framework, I end up regretting it in the end and seeing the wisdom built into the original.
I guess this might be a problem with how I've handled errors in the past with QMH. I tended to allow a thread/handler a chance to handle the error, then pass the error back to the main thread/handler. Eventually it would be displayed to the user. I tried to push this concept into actor framework and have nested actors report the error to their caller until landing with the root and being displayed. This means that my default was to let it live and continue on which is what interrupted the stop codes. Is it better to just let the nested actor die and try to recover?
What might have lead down this path was an unreliable parse-able serial stream from a particular device. I didn't want to bring things to a halt, but I wanted things to be handled and/or displayed in case it was important.
That's a bit facetious, but I created the AF back in 2010, and in the years since, I've become more nuanced about error handling. When people use the term "error handling", they actually are referring to FIVE separate and somewhat independent things:
The VI in the actor framework should be named "Propagate Error.vi". This VI is called after a method has already said, "I don't know how to react to this error, so I'm passing it to my caller." In Propagate Error, it is appropriate to
That last one is what you were asking about. It's a pretty advanced use case, but quite valuable. But if you do #4, notice that you are sending the error along to the caller in your own message. You aren't relying on the AF to propagate the error. If you return an error from Handle Error.vi, it means "Not only did my method not know how to deal with this situation, my whole actor didn't know how to deal with this situation, so the actor is going to go away now, and the message will go up to the caller (in the form of the Last Ack), and the caller can figure out what to do."
If you are in a parse method and you just want to display or log the error and continue operations, I suggest that you should NOT return that error from your method. Instead, that's part of the behavior of the actor's method: it sends a message to caller saying, "Caller, please display or log this error, whichever one you're doing." Then it clears the error and continue parsing or ends the method and the actor goes back to waiting for its next message. That's correctly handling the error.
Let me first say that I regret picking error code 43 (Cancel Error) for normal stop. I should have grabbed a unique error code. It has caused a few minor problems over the years. But setting that aside, I would still use error for stop if we redesigned from scratch today.
There's a few reasons. First of all, we have to have Handle Error (or its renamed equivalent) one way or the other -- we need the Do.vi to be able to return an error. If we don't, we have to make error a part of Actor's state, which bloats Actor needlessly. You are correct that "stop" could be a part of the Actor state, but it wouldn't be a Boolean. It would be an enum to specify "not stopping", "normal stop", or "emergency stop". But then people would want to include a reason or metadata about why it was stopping... which turns it into an error cluster, essentially, and we're right back where we started.
It's funny because this notion doesn't even tempt me anymore. Like I said before, every time I fight/alter a framework I regret it later. Hence why I appreciate this post so much. This should hopefully help me reshape my preconceived notions.
If I delete the table from the diagram by selecting it and pressing del, then in the Model Browser It disappears from the .Database but when clicking "Update model from Database" I can't see i in the "Add" list, all I can do is "Refresh" the table since I still see it in the refresh list (which should not happen because I deleted it! )
I had this issue when I changed a column name from CampaignKey to CampaignCode. After making the DB change, I went to the .edmx designer, right clicked and chose Update Model from Database. Then when I compiled I got the error:
Taking a closer look at my table in the designer showed me that Visual Studio had created the new field CampaignCode as in the DB. But it also had left the old field CampaignKey in there, causing the error as it no longer exists in the DB.
I have gotten this same error before when column names on tables or views change case. For example, if a view has a column named "OrderID" and then the column name is changed to "OrderId" then it will give the error 'Property "OrderID" is not mapped'. This can be resolved by changing the case back to how it exists in the model.
I know this question was about VS 2008 and 'recovering' a model, but for anyone who finds this like I did when I had the same Error 11009 in VS 2015, I first tried the "Update Model from Database" to no avail, then I finally fixed it by right-clicking the model table in the .edmx design and choosing Table Mapping. I did not have to delete the model. My model is associated with a db table.
When we add entity model into our project, it adds a corresponding connection string to web.config. Now, when you delete the model from project, even then the connection string still resides there in the web.config.
The easiest way I've found to deal with this is to find the model/table with the unmapped property in the edmx. Select it and delete it. Save your edmx and then update it again, adding the model back in from the database. Deleting just the unmapped property didn't work for me.
In my case I added a new scalar property named sys_user_id to an existing table in the Designer inside Visual Studio. I didn't update the Model from the Database because that was causing a lot of errors in the designer. I just wanted to map a single column that was added to a given table on the database side.
After changing it in Visual Studio Code and getting back to Visual Studio it asked me to reload the .edmx file since it was modified. Reloaded and then hit F5 to run the code. It started working as expected.
It seems like basic troubleshooting is giving us no luck and thanks for the effort. I'd suggest getting additional help from the channel team and see if this is a common error or an isolated case. Most of the channels on Roku are handled and developed by the service providers themselves, and any issues that may be encountered would need to be reported directly.
