how do you search a string for capital letters, is there a function I can use to return to me how many capital letters are in a string? I have tried searching this but as yet not stumbled across a function. Most functions I found converted lower case to upper case Etc. I thought InStr might be the one but still looking for information on that one. I did find something along the lines of .char.isupper but the textbox is .text A password 'rating' tool of sorts of which I use a counter so if I enter "STRing" in the textbox for example it will return a 3 add it to the counter and continue with the little algorithm which my rater uses to add up things such as numbers or special characters to get a final score and that indicates to the user how strong the password is.
I'm searching for specific string method that ignoring the word if it was written in capital or small letters when I want to type this word in a field for searching purposes or when a user wants to enter its usrename in capital or small letters.
what i want to is convert this string to something like this
2. JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3
both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.
Quick question here about how to get it to accept capital and lowercase letters. I am running code that has certain Customer Types such as "T". It returns different information for that customer. There are only 3 types "T", "R", and "C". The rest return the default information. When I enter "t" into the textbox it returns the default information, not the information for "T". How do I go about getting it to accept "T" or "t"?
I need that a particular column in a DGV necessarily be written in capital letters, without the user having to press "BloqMay"... for the rest of columns the user will write normal.
I want to know on how to convert small letter to capital letters. I want to convert every letter automatically once I press the keyboard. Im going to wait for your replies.
I have a datagridview with 4 columns bound to a datasource. In the first column the user can only type numbers, in the 2nd, 3rd and 4th only letters (done with keypress and editingcontrolshowing).
Now I want that the user's input in the last two columns automatically gets converted to capital letters, regardless whether he is using Shift or has Caps Lock turned on.

My only problem is that when I double click a cell in the 3rd or 4th column (those where I want uppercase letters) and then one in the 2nd column, the text in the cell in the 2nd column is showed in uppercase letters too.
Note: It only shows the already present letters in uppercase. If I type extra letters they will get normal font (so lowercase if I don't use shift or caps lock, and uppercase if I do use shift or caps lock). If I don't type any letters and unselect the cell the text changes back to as it was before selecting.
If I double click another cell in the 2nd column (after i clicked one in the 3rd or 4th column and then one in the 2nd column), the present text stays the same, so it don't get showed in uppercase letters.
how it comes that only the first time that I double click a cell in the 2nd column after i clicked one in the 3rd or 4th column the present text gets converted to uppercase letters and, more important
If I have a RichTextBox and want output like the first line is a font with capital letters and bold, while the next line on the contrary, what should I do?
I want to do is have textbox1.text show 10-20 characters that are random letters and numbers when i press button1. I have tried to do this but I am not so great with generating anything that is random. If possible have it be a mix of Capital and Lowercase letters.
I want to check for the letters of the given string. for example: the string = Visual Studio next is i want to check per letter of the string. next I want to change V to x
I haven't programmed for some time, so I'm a little rusty Basically I'm storing HTML within a variable, and I need to count the amount of times a specific element appears e.g. <h3 class=r> for now.
I thought of using a for each loop, and passing the string above into the parentheses of the loop (using a variable ofc) however for many reason's, I don't think this has a chance of working (won't bother explaining why, as I assume you can guess). Then thought of using the .Contains method of the string class, but I simply can't think of how to use it with what I'm trying to do.
Okay so i have a very large list of string (500 000 strings) i want to check the number of duplicate strings and maybe even isolate the duplicate strings if i can.
i cant find a fast method to do so :S
i tried using a string array (slower than list) takes ~15mins
i tried using list with the code below takes ~10 mins
I'm trying to make a program that takes input from the user and take what they put in an take every letter and give it a value. Like a code or something so if they have "Apple" then it changes to something like "122515" so[code]...
im looking for a code setup where the program can get a numerical value based on letters in a user inputted string, and output the value A=1, B=2, C=3, etc
for example, string="trujade". how would i go about randomizing the letters in the string to look like the matrix code? change each letter in the string "trujade", randomly to a different alphabet letter. [URL]
I'm trying remove non-letters from this string I have. I have an order form for hats and T-shirts, they select everything and click on buy button there order info shows up in a listbox. For the results in the listbox I break down there order info and show there total price. Well the string I have for the sizes comes up with Medium "7 1/8 - 7 1/4" in the list box. I want to remove non-letters and have it just show "Medium". I try using the instr function and the trim function as well but nothing is happening.
This seems a simple enough thing to to but its giving me problems. What I have is this; a text box the user enters a word into, then a btnReverse that when clicked should cause the inputted word to display in reverse in lblReverse.Text. What seemed to me to be the easiest solution was this;
Option Explicit On Option Strict On Option Infer Off Public Class frmMain
I have a string of randomly organized characters and I am trying to search a wordlist for matches. If the wordlist has a match I want it to add it to a listview. I wasn't for sure how to word the first two sentences and I think an example will help explainmy problem better. So here is an example. I have a textbox where you input what you want to search for in the wordlist. Lets say you type in tca . The wordlist contains cat frog dog , each word on a separate line. What i want to do is take what you typed in the textbox, tca , and find the word cat in the wordlist.
So I basically want to make sure that a string entered by the user is valid. Valid being over 10 characters, containing only upper case characters, and only characters A - Z and spaces. The first two were easy, but I'm having trouble with the third, though.What I originally attempted to do was create a loop which checks if the first invalid character is present with the InStr function, by using the characters ASCII value. The next ASCII value is then checked, and so on until it has checked the string for every single invalid character. If an invalid character gets picked up, 1 is added to a variable, and after the loop is finished executing, if the variable is no longer 0, invalid characters have been detected.
I am making a question and answer game, and I would like to be able to give the user some slack in the answers if they were to misspell a word by a letter or two, like if the answers was Jumps and they type Jump if you did a comparison of them like If string1 = sring2 then do whatever, but obliviously those to string dont match, so it would return false, even though it is the right answer, I came up with this routine to compare two words and if the percentage of the letters are higher then 82 % right it will give you credit for your answer.
