I'm trying to find a way to have text that would be "Live" as in if a user types an incorrect phrase/letter in a text box, a message will appear prior to a "save" button being pressed. It's pretty much the same as when you're registering on these forums, it checks the availabilty of the username as you type it.

View 4 RepliesAlright. I have a project I need to complete by 11:00 am today. I need a program that will allow a user to input a phrase into a text box. Another text box to input a letter. Then I need the program to count how many times, the letter appears in the phrase. I have everything set up. I know how to count how many characters are in the string, but not how many designated letters there is.

I am trying to make a program which goes through the HTML code of a page and then searches for a certain phrase. I have gotten up to the point of executing a search on a site and then dumping the html code of the body.How would I go about doing this?
The phrase I'm looking for is "<tr><td><a
href=javascript:d(87178)>Name of File</a></td><td>Date Submitted</td><td>Likelyness
to work(%)</td></tr>
All I would need to do is find the number inside of the parenthesis (87178) in this example and I THINK I'm good to roll, so how would I do that?

View 7 RepliesI'm trying to identify if the input of a textbox is non numerical, which cannot be converted to an integer/double for calculation. I do this by converting the input1.text to ascii, and looking at the value to determine the type of input. My question is whether there is any way I can analyze the whole input character by character? Asc() only gives the ascii value of the first character, but what if the input is "9W" etc? Such inputs will pass my character test, but cannot be converted to an integer.
View 2 RepliesI'm a VB beginner.I wonder if it's possible to change the text style letter by letter?I've learned here that you can change the entire style of text like

TextBox1.Font = myStyle

NOTE: I tried using concat() method, join method and even tried to insert just text(which turned out editable) but none of them worked as I wanted. I was thinking if substring method will work but I only have basic idea of how substring works. I want the letter "N" to be inserted into the text box when form loads and when the user enters 4digits(OrderNo2.text) which should be joined so that it can be saved together when I clicked on save button.

On the main form of my application, I have a Rich Text Box which is where the user will be entering information. The text is black. then, i have a button which calls the dialogue "Notes" A dialogue appears, with a rich text box. the user should then be able to enter text into the box, click "OK", and the text entered into the Notes dialogue be inserted to the rich text box on the main form -- with the font colour "Red". The rest of the text in the main rich text box on the main form should remain black.
View 2 RepliesI'm Making a Simple syntax highlighter and I'm Doing the highlighting in the text Changed event of a RTB and for obvious reasons I can't re highlight the whole document each time someone presses a key so i highlight one line each time the text changes. But this creates a Problem. If someone pastes code into the RichTextBox It only highlights the last Line. So is there a way to get if the user typed the text in with his keyboard or pasted it from the clipboard in the text Changed event?
View 6 RepliesI know this is probably simple but I think I may be phrasing this wrong. I'm trying to make textbox text available as soon as it's entered on a label. The below code is what I used for a click event, which generates the info I want to see(I know a live preview would make a display button redundant, but our teacher requested both). If anyone can just tell me the proper terminology,
Private Sub ButtonDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonDisplay.Click

I have a program which writes to a .log file as it is installing software. Some of the lines will contain either WARNING or FAILED.
What I would like, is a window in my program which will read the .log file and display the content into this window as it is being written too. Any lines which contain WARNING or FAILED in them are highlighted yellow/red.
I'd like to make a custom control that allows the end user to format the text, similar to an HTML or RichText control. The idea is that it will be static like a label, but allow end user to specify certain tags around words to make them bold, italic, underline, hyperlink, etc, either at design time or runtime. My question more specifically is how to best approach this. My intention is to use GDI+ methods, like DrawString, etc. But my concern is the inefficiency of having to parse the text each Paint cycle to determine which tags are present in order to use the correct font style, etc. I'm not really asking HOW to do this, but more of a hint on which architectural approach to take on this. Maybe there is already some examples of this out there?

View 1 RepliesI have created an application which will open a text file on the click of a button, when i am running the application in local, I am able to get the popup asking to open or save the text file, I uploaded the same code to live site there it is not displaying the popup to open or save the text file. It just flashes a window for fraction of seconds and then closes, user is not able to perform any action in that course of time. Text document which I am trying to open is available at both server and local, and path is also correct in both cases.
Below is the code I am using to open the text file:
If (File.Exists(strFolderPath & "" & strFileName)) Then
objFileStream = New FileStream(strFolderPath & "" & strFileName, FileMode.Open, FileAccess.Read)
objStreamReader = New StreamReader(objFileStream)
objStreamReader.BaseStream.Seek(0, SeekOrigin.Begin)

In this exmample textData is a string of text and alpha is a single letter a through z or A through Z. I don't need the criteria to be case sensitive, but I do need only the first letter of textData to match alpha. I have tested the LIKE comparator and it does not return all records that begin with alpha.
