Get The Program To Start Back Over And Enter Another 2 More Words If The String Is Not 20 Characters Long
Sep 27, 2009
I have a program that requires a string. The string is 20 characters long. The string also have to be split into 2 words the first word is 12 characters and the second is 8. If the strings is not 20 characters long I get an error. I wanted to know how can I get the program to start back over and let me enter another 2 more words if the string is not 20 characters long. At the moment after I get the string is not 20 characters long error it continues to read the rest of the program but I want it to stop after an error and let me start over from the beginning.

I am trying to strip the first 75 characters from various strings (sentences / phrases) and it seems right but I need to ensure that the now words are truncated in the process. Meaning that if the 75 character is part of a word it needs to fall back to the beginning of the word or nearest space..
I thought of stripping the entire string into separate words and then counting the length of combining the words and stopping when I reach the target but what do I do in the case when it is not a valid sentence just a bunch of characters jammed together. I thought of using grammar parsing tool libraries and parsing into tokens etc but that seems to over complicated.
if text.length() > 75 then
ctext = text.remove(text.length, 75) & "..."
endif
I put elipses at the end but using the above I also get the error:
does anyone have any better suggestions.

I have an HTML string and in that string are certain variables that I need to replace with database values. The variable names are dynamic but all begin with the characters "@@" (just two ampersands, no quotes). Is there a way to get all the words in a string that start with "@@"? I'm assuming you would use regular expressions, but not sure how to begin.

I have a situation where a user can enter just about anything they want into a text box.Whatever they enter in the box, I need to split the string into an array of strings where each item is one word. For example, if the user enters All State Insurance, I split that into a string array:
sParams(0) = "All"
sParams(1) = "State"
sParams(2) = "Insurance"

I have a task to resolve, it is regading extracting characters from a long string to the console, the extracted text shall be reformatted and saved into a CSV file. The string comes out of a database.
It looks something like: UNH+RAM6957+ORDERS:D:96A:UN:EGC103'BGM+38G::ZEW+REQEST6957+9'DTM+Z05:0:805'DTM+137:20100930154
The values are seperated by '.I can query the database and display the string on the console, but now I need to extract the Keyword 'ORDERS' for example, and lets say it's following 5 Characters. So the output should look like: ORDERS:D:96A then I need to extract the keyword 'BGM' and its following five characters so the output should look like: BGM+38G:After extracting all the keywords, the result should be comma seperated and look like:
ORDERS:D:96A,BGM+38G: it should be saved into a CSV file automatically.
I tried already:
'Lookup for containing KeyWords
Dim FoundPosition1 = p_EDI.Contains("ORDERS")
Console.WriteLine(FoundPosition1)
Which gives the starting position of the Keyword.I tried to trim the whole thing around the keyword "DTM". The EDI variable holds the entire string from the Database:
Dim FoundPosition2 = EDI
FoundPosition2 = Trim(Mid(EDI, InStr(EDI, "DTM")))
Console.WriteLine(FoundPosition2)

I am creating a WPF Application that uses Fluent library.
On my computer with Windows 7, 2GB RAM and AMD Triple Core processor, after double clicking on the program icon, The Splash image shows after about 1-2 seconds.
But on my brother's old computer with Windows XP, 512MB RAM and Intel Celeron 2.0 GHz Processor (Single core), after double clicking on the program icon, First, a process called PresentationFontCache.exe runs and it uses almost 100% of CPU for some seconds. And Total time is needed for displaying the initial Splash image is almost 30 seconds (or more).
I don't want that some users have to wait 30 seconds for displaying splash image and about 7-8 seconds for loading application. (my application load process takes 7-8 seconds)

My homework assignment is to create a project where a user enters a password that must be at least 3 characters long with at least 1 number and 1 alphabet character. After that the password has to be encrypted so that vowels become X, numbers Z, and it reverses. For example, a password of CS2301 would be ZZZZSC. There's supposed to be Loops to extract 1 number/letter at a time and search for them in the string to validate, and I don't know what to do. The form itself has a Text Box to enter a password and a label to display the new one, and a Go button.
This is what my code looks like so far.
Option Strict On
Option Explicit On
Public Class Form1

I wrote an app in Visual Studio and is about 20k+ lines, but I don't know why it takes so long to start up. I have a splash screen just to test it to see if the program is working, and it is, but I have to wait for so long for the app to actually get to the start up form. A splash screen for this app isn't ideal, but was only using a splash screen for test purposes.

Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

Is it possible to open another app without losing focus of the current foreground app? I have a program that will open another app and test something on it then close it, and reopen it again and repeat. Can this be all done in the back while i am typing away on another app in the foreground without getting interrupted by the new app opening and changing focus?
i dont want the new app open minimized or anything, just quietly open in the background.
I tried using process startinfo.windowstyle and that doesnt help much.

I've got a function api_request which takes API method as an argument, and returns XMLTextReader.
Shared Function api_request(method As String) As XmlTextReader
request_text = method & ".xml"
url = "[URL]" & request_text & "&access_token=" & token
Return New XmlTextReader(url)
End Function
I call this function from different places to make request to site API and depending on the method results are parsed very differently. So in each method I have something like this:
Dim s As Xml.XmlReader = api_request("users.get")
While s.Read
If s.NodeType = XmlNodeType.Element Then
If s.Name = "user" Then
[Code] .....
As you may see, I have the code ElseIf s.Name = "error" Then error_handler(s, "user.get"). This is because when error happens, server always returns something like this:
<error>
<error_code>4</error_code>
<error_msg>Incorrect signature</error_msg>
</error>
This is parsed in error_handler Sub, and depending on the error following actions are chosen. This code works, but I have to check if I encounter error like that ElseIf s.Name = "error" every time, though all the methods call the api_request function. Is it possible to check for error in api_request function before returning the Reader? The problem is if I start reading xml there, and there isn't an error, I can't anyhow position the Reader to the start.

I want to create a program that checks the characters of the string "George123" . If a number is found in the string then a message box will pop up. Here is where the problem lies. I created a for loop that inspects each character of the string George123 and when it reaches the number 123 the message box pops up. The only problem with the message box is that it appears 3 times as there are three numbers in the string. So my question is how do i exit a for loop right after the first number is found in the string.
Code:
Dim onecharacter As Char
Dim Enter As String
