At last I found what I was looking for.

[@samiihaq]

Is there a way to ask for users input and save in the listbox permanently?

[@quanhoang2139]

thanks you so much

[@juliancastelan9664]

why does my source collection not allow me to paste multiple lines?

[@micahparker5297]

Because it wasn't designed for that... It can't comprehend it when you paste something. It is waiting for you to type, not paste.

[@master765gt8]

Can you do it like you have the text box and if you press yes it will open up an different text box and if you press no it will open a different text box?

[@micahparker5297]

No.

Hi do you have any tutorial how to serach word's in textbox nad display on textbox connected with database where you have a tabele coled vacobluary. In that tabele you have only Question_ID, Question_Name And Question_answer. So if you tape in textbox word will serach in tabele and populate the answer if it match with data? Thank you

[@micahparker5297]

No.. Sorry. BUT, I have a solution, here. www.codeproject.com/Articles/365974/Autocomplete-Menu An autocompletemenu, which can give you suggestions for completing text, just by making a String[] Array, right from the AutoCompleteMenu properties panel! More info is in the link.

[@advaitkale1782]

Connect auto source to Database???

[@andilesimelane4771]

Hi thanks for this can we also do it in Java, using netbeans

[@micahparker5297]

Impossible. Sorry, @Andile Simelane

[@LearnKinyarwanda]

Hi! Kindly let me know how to use a textfile located somewhere in my computer's directory as an autocomplete source, instead of using a custom source!

[@micahparker5297]

That isn't possible, IMHO, because Microsoft hasn't 100% developed that yet. Regards

[@pratikawate5826]

I am getting an "Invalid Cast Exception" I tried everything but none worked for me please help🙏

[@prahaladkumar3802]

i like this video .

[@rajanj8058]

I am creating a spelling game and want to know how I can create a textbox (using C# or any other program) so that once a word is entered, it detects whether it is right or wrong and accordingly comes up with a correct or wrong message?? Any help would be appreciated!!!

[@kipchickensout]

Did you finish your game yet?

[@H.B-Records]

Thank you very much

[@baalagee]

May i know how to load current project directory in text box? can u explain sir?

[@micahparker5297]

- Won't work. Since VS(Visual Studio) is already using that folder/file, it will come across with an error-dialog: "An error has occurred! It seems the file you are accessing is being used by another process. Please shutdown the other process." Sorry, bud.

Sir how to create textbox auto complete from c# database data

[@HeapKhim]

Oh very good brother. I want to create dictionary so what can I do brother?

[@mdmohiyuddinkhan]

hi all, the autocomplete textbox is searching from starting, i want something like string search, example if i type a then it has to show all words which has a. The same like in phones now a days come for contact search. can any body helps me on this... it would be great help. I want this for C# windows application. for Web application through ajax tool kit it is already there. Thanks

[@kentdmayor]

Tried to to this but for some reason, it won't work even though I already followed the instructions correctly and carefully. Need help, please

[@micahparker5297]

Hmm, use this: www.codeproject.com/Articles/365974/Autocomplete-Menu

[@MarioAxl]

You should have framework 4.8 installed, Con el framework 4.8 aparecen más propiedades. para los que no encuentran el autocomplete.

[@doge7831]

It does not work with rich text boxes

[@fadilibrahim]

👍👍

[@tuanphamhoang87]

why can't textbox execute autocomplete when i choose multiline?

[@micahparker5297]

Because, the AutoComplete isn't meant for multiline. If it was, I'd bet that they would have added an AutoComplete for RichTextBox. Also, the maker of this video seems to be ignorant, so I will answer your questions. Regards

[@TutorialsMethod]

sir! i want to make auto complete like programming editor when we write our code any where it gives us suggestions ..can you help me please i am waiting for your response

[@micahparker5297]

That is a tall order - I suggest doing this: Make a syntax highlight. If they are inputting the right code, it will highlight the syntax in a color you want. If they aren't, you can totally highlight it in red or something. I don't have sample code, but search it in google and you're bound to find something that peaks your interest. Regards

[@bmzih]

@@micahparker5297 can you help me. I've got an assignment where I need to develop a simple IDE that supports C#. The problem is that they want where if you write a wrong code, it highlights it. Just the way you write a wrong code in Vb there is a red line that shows it has errors. If you have any suggestions it can help

[@micahparker5297]

@@bmzih Oh, I see what you want -- Luckily, this is really easy. So, you want to highlight it in Red? Sadly, you can't do red under-lining, but you CAN color the incorrect text. Here, use this: // getting keywords/functions string keywords = @"\b(abstract|as|base|break|case|catch|checked|continue|default|delegate|do|else|event|explicit|extern|false|finally|fixed|for|foreach|goto|if|implicit|in|interface|internal|is|lock|namespace|new|null|object|operator|out|override|params|private|protected|public|readonly|ref|return|sealed|sizeof|stackalloc|switch|this|throw|true|try|typeof|unchecked|unsafe|using|virtual|volatile|while)\b"; MatchCollection keywordMatches = Regex.Matches(codeRichTextBox.Text, keywords); // getting types/classes from the text string types = @"\b(Console)\b"; MatchCollection typeMatches = Regex.Matches(codeRichTextBox.Text, types); // getting comments (inline or multiline) string comments = @"(\/\/.+?$|\/\*.+?\*\/)"; MatchCollection commentMatches = Regex.Matches(codeRichTextBox.Text, comments, RegexOptions.Multiline); // getting strings string strings = "\".+?\""; MatchCollection stringMatches = Regex.Matches(codeRichTextBox.Text, strings); string stringz = "bool|byte|char|class|const|decimal|double|enum|float|int|long|sbyte|short|static|string|struct|uint|ulong|ushort|void"; MatchCollection stringzMatchez = Regex.Matches(codeRichTextBox.Text, stringz); // saving the original caret position + forecolor int originalIndex = codeRichTextBox.SelectionStart; int originalLength = codeRichTextBox.SelectionLength; Color originalColor = Color.Black; // MANDATORY - focuses a label before highlighting (avoids blinking) menuStrip1.Focus(); // removes any previous highlighting (so modified words won't remain highlighted) codeRichTextBox.SelectionStart = 0; codeRichTextBox.SelectionLength = codeRichTextBox.Text.Length; codeRichTextBox.SelectionColor = originalColor; // scanning... foreach (Match m in keywordMatches) { codeRichTextBox.SelectionStart = m.Index; codeRichTextBox.SelectionLength = m.Length; codeRichTextBox.SelectionColor = Color.Blue; } foreach (Match m in typeMatches) { codeRichTextBox.SelectionStart = m.Index; codeRichTextBox.SelectionLength = m.Length; codeRichTextBox.SelectionColor = Color.DarkCyan; } foreach (Match m in commentMatches) { codeRichTextBox.SelectionStart = m.Index; codeRichTextBox.SelectionLength = m.Length; codeRichTextBox.SelectionColor = Color.Green; } foreach (Match m in stringMatches) { codeRichTextBox.SelectionStart = m.Index; codeRichTextBox.SelectionLength = m.Length; codeRichTextBox.SelectionColor = Color.Brown; } foreach (Match m in stringzMatchez) { codeRichTextBox.SelectionStart = m.Index; codeRichTextBox.SelectionLength = m.Length; codeRichTextBox.SelectionColor = Color.Purple; } // restoring the original colors, for further writing codeRichTextBox.SelectionStart = originalIndex; codeRichTextBox.SelectionLength = originalLength; codeRichTextBox.SelectionColor = originalColor; // giving back the focus codeRichTextBox.Focus(); - Is this what you needed? Put it into the TextChanged event of a RICHTEXTBOX. Don't do textbox, they don't have certain requirements for it. This happily creates a Syntax-Check, without needing to install a Nu-get package. If you need C# Syntax, then use this. I inputted all C#-Keywords in correct coloring(From the Microsoft Site.), so you will maybe only need to double-check it once. So, in summary, this code will highlight any C#-Code the user inputs into the RichTextBox. I made it color it BLUE, but, you can change any of them, if you want to. Basically, if the user inputs Non-C# Code, then it will NOT be highlighted in blue(or whatever color.) Instead, it will just be regular text. If you want something more, ask me! If you need help with anything else, I am always here to help. Thank you for asking, @Ned Regards, Micah

Can you give us the source code

[@bothannwinn870]

my android studio doesn't contain Design mode? Why?

[@doieslovebot9289]

Hello, is there any way to use autocomplete with multiple words inside the textbox?

[@micahparker5297]

You'd have to re-code the textbox to do that. Sorry. Regards

[@micahparker5297]

@@mondron Actually, my first comment was incorrect. A good AutoCompletion is here: www.codeproject.com/Articles/365974/Autocomplete-Menu It is compatible with both RichTextBox & TextBox Controls. I hope I helped you :)
