I am using Reactjs in an ElectronJS project. There seems to be an intermittent problem where when i type some text in a textbox it types in reverse order (screenshot: https://share.getcloudapp.com/DOuxq0b2).
This happens sometimes (on both windows and macos) when I select a pre-existing entry and start typing over it (without hitting delete first). But doesn’t always happen consistently. I am not sure why this happens and most of the times i am unable to reproduce this. My program simply saves the data that is being entered in a state on the onChange event. I am not even sure if this is bug in Reactjs or html.
I was wondering if any of you have faced this when building projects with react or electronjs, if so how did you fix this?

using V2.0.0.5 - beta (not via nuget but compiled source).
All through out the application I am using Multi-View over single ViewModel. On one particular view now after a conversion from SQLCE to SQLite, I am getting either a race condition or invalid contextual return when it builds up the on the InvokeAction. One thing I am noticing is a ArgumentException on System.Windows.ni.dll and well the part of the problem is the Telerik Control primitives.dll... RadTransitionControl
The only difference between this view and another with almost exactly the same build out is the way I populate the view. The view is using a "non-table" viewmodel that I built up to show some related information between 2 related tables. When I selected one of the elements in the boundlist it presents RadMenu (edit/delete) selecting edit works goes into the method expected, using the data passed in from the selection event I am able to re-hydrate the dataitem in question to respective objects. And populate the view but it dies before completing the transition from view to view.
The thing that blows my mind here is that I am using that control all over for Transistions from one view piece to another, if I change the control to ContentControl it works just fine. Other views that have that control work as expected. Any ideas?
Moving some of the code around and separating some of the bundled code resulted in this not occurring guess problem fixed...
It seems like lately I have been having been getting hung up on the auto-completion drop down when using the console in Chrome DevTools. It seems like it has suddenly gotten more aggressive. I have never had a problem with the feature until the other day when I was trying to enter commands into the console quickly in order to test things. I wasn't sure why it wasn't working right. when I'd hit Enter auto-completion kept popping up and not executing what I typed. At first it seems as if auto-completion was activating whenever I would hit Enter to execute my code. However, it began to look like it was only popping up when I would end a statement with ;.
For example, typing the following statement into the console and pressing Enter would not cause the autocomplete drop down to activate:
console.log('did it')
However, if I add a semicolon then as soon as I press ; a number of milliseconds later the autocompletion feature immediately pops up:
console.log('did it');
At this point if I press Enter it will simply select the first entry, $, and add it as the next statement so we get:
console.log('did it');$
I know this is not really a big deal, after all, the only reason you would need the semicolon is for entering in multiple statements. However, I feel like in the past I've always added a semicolon ; to the end of simple single test statements such as the console.log shown above not activated the auto-completion, being able to execute it by just hitting Enter.
I definitely feel like my console's auto-completion is being activated more aggressive than it used to.
Has anyone else felt like the auto-completion in the console is activating too often all of the sudden? I am wondering whether or not this could have actually been changed in Chrome or if somehow I have made my console start acting this way with a setting or something?
While writing this I noticed that it seems not to only be after ; that auto-completion seems to pop up when it hadn't before. If you refer to Chrome DevTools - Using the Console you'll see that auto-completion is only referred to once:
The Console attempts to evaluate any JavaScript expression you enter at the shell prompt, upon pressing the Return or Enter key. The Console provides auto-completion and tab-completion. As you type expressions, property names are automatically suggested. If there are multiple properties with the same prefix, pressing the Tab key cycles through them. Pressing the right arrow key accepts the current suggestion. The current suggestion is also accepted by pressing the Tab key if there is only one matched property.
After this it goes on to say that we can use Shift+Enter in order to enter a multi-line expression and it gives the following example:
(source: google.com)
This is something I know for sure I have done plenty of times in the past with no problems from auto-completion. When I try to type the code in the above image I get as far as:
var add = function (val1, val2) {
Then when I press Shift+Enter instead of going to a new line like I am positive it did before (for me at least). Apparently anytime a new statement is started it will pop up. Has anyone else started getting highly annoyed at this feature as of very recently? Does anyone know if there's a way I could have caused this behavior?
Whoever answered my question before deleted their answer. I would like to close the question as it has been answered. This is indeed a bug as stated in the comments above and on the deleted answer. Anyone else that is here because they are experiencing problems as well will have to wait for the release to make it down to their version of Chrome, with Canary getting it first of course. You could presumably install an earlier version of Chrome to get around this as well. I know this is not directly about coding, but I see no reason to close it now when others may find the information useful.

I have a form with text inputs, check boxes, radio buttons, selects and an AsyncFileUpload control.
All of the selects are dynamically populated from the code behind, and one of them has a Select One added (which is removed when another option is selected) from my page controller object.
I have verified that none of the page's javascript is running in conjunction with the upload control other than the script that directly controls the client functionality of the uploader.
If I do not touch any of the other fields and attempt to upload a file I get an Unknown Server Error.
If I change away from the Select One option (which, again, makes the option be removed), I can now upload an image. My solution is to add the option in code behind and remove it once an option is selected from the client, but my question is this:
Why do I get this error? What is the reason for it?
I found the reason. My Select was an asp:DropDownList, and my code was expecting the returned data to be validated. Since I had changed the value from javascript it was no longer the same as what the server had sent, causing the exception I was seeing. The solution is to do those changes from the server instead of on the client. Simple solution to a perplexing issue.
I have a very strange problem. I load my app, switch to the correct tab and then press the button I need to press. This runs a function and when I first load the page it may only provide part of the correct result. However if I wait a few seconds it produces the correct result in full. Any ideas why this might be happening?
Additional Information
The button simply checks through a list of objects returned via ScriptDB. Objects that are valid are displayed and objects that are in-valid are not. If the object appears again in updates the text to display how many have been found in the list (eg: the label would change from "Object A" to "Object A (2)").
It seems to me like it doesn't have the rest of the list somehow as it doesn't always stop at the same object. It's Very strange and not something I've experienced before. The other features of my app using ScriptDB work completely regardless of how quickly I use them.
I've figured it out now. I somehow had some erroneous data in the database which was returning a null field. I can only assume that this was from a import that I did last week from a spreadsheet.
This was copied from my comment to show that it has been resolved.
Got a weird problem. I was debugging some code for a form and everything was working as intended for the most part when suddenly I began to get a "Method or Data Member Not Found" for every event of my form. It's like my form suddenly does not recognize any of my controls or events. I have all of my methods properly closed and did not rename any controls.
Any ideas on what would be the root of "Method or Data Member Not Found" for every single control with an event?
Thanks
Importing into a fresh database as talbright suggested gave me more descriptive error messages.
A fresh import, compact&repair, and renaming of appropriate control fixed the problem from occuring. As Remou suggested, regular maintenance can help prevent these sorts of problems.
edit for future readers: This problem occurred while using a shared front end file. So don't do that if possible.
I've found that any MISSING: reference can make the simplest of code fail.
Check in the visual basic window
Menu Tools -> References
look down the checked refences to see if any are MISSING
I just fixed the same error by renaming text and combo boxes something not so close to a concatenated Table & Field string. Actually just prepended those names with "tbx" and "cbx".
