Making The Rules Of A Text Box?
Jan 15, 2012
So for the important part, right now I'm planning on creating a word detector somehow and there are specific rules I was to set in the textbox in relation with the button.Let's say I wanna set an IF Statement for the text to have 32 characters and letters "abcdefg" and numbers "12345" so that it'll execute a message box when I press the button.
Here's a code example of what I'm saying
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

If we won't know what Exception will be thrown then why cannot we catch a general exception? I just cannot follow this and some more.

I was having a discussion with a colleague about a method used to check business rules. In general there are two conditions:
"If one fails the whole thing fails"
Example 1: "If one fails the whole thing fails"I have used the following technique for condition 1 in several cases. Essentially if one of those conditions is false then the whole thing fails
Dim blnTemp As Boolean = True
If Fail=False Then blnTemp = blnTemp AndAlso False
{code code code}

Any way to apply some validation rules to the following code?
VB
Private Sub dgOperator_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgOperator.EditingControlShowing
Const cSUBNAME As String = "dg_EditingControlShowing"
[Code] .....
Another thing should I be applying this validation on the Id Op'rateur column or when I click to the edit the next column in the datagrid i.e. Description?

I have created a system in Visual Basic 2010, which is to check on the existence of files attached in a access database. However there are different types of records in the database that will have to be checked against a different set of rules than others. For example one type of record will have to be checked to make sure certain named text files are there. However a different type of record will check for another text file with a different name e.t.c.
I have worked out that in order to do this I need a set of rules that the code in visual basic can match against and run that code depending on the choice. For example one type will execute rule 1,3,5 and the other type 2,4,6. I thought that these could be done in an XML document but am not too sure.

So I know it's possible to store Users and Roles on SQL server but I was wondering if it was also possible to store the access rules on SQL Server. I've searched but I can't find anything.
Our auditor requires us to run reports that tell us which users have access to which websites. Currently I am parsing each web.config file to see which users/roles have access, storing that in SQL server and running a report off of that but I am hoping there is a better way.

I have a simple business rules engine that I need to write. I have looked at both Biztalk and Windows Workflow, but they are to much for what we need to do. This is a process that material will come to an operation, the GUI will check for three rules, one for the operation, one for the steps in the operation, and one for the item coming into the operation. These are the only three checks that will be done. It is possible there will be more than one rule for each check. I have a simple database set up to contain all the operations, steps and products and there is a crosstab table that links all the rules to each item. Here is an example of some rules (these are actual rules from the process):

i'm doing a project for school which requires me to make a fully functioning database program with validation. I'm done with almost everything except a few things and that includes the database, since i don't really know how to make validation rules and masked fields.It's possible i'm guessing to in forms and such but in datagrid view?

Rules:
Rule 1: Replace all of the vowels (A, E, I, O or U) in the original password with a number as follows: (20 points) Replace the first vowel with the number of 1. Replace the second vowel with the number of 2. Replace all other vowels with the number of 9.
Rule 2: Replace all of the numbers in the original password with the letter Z. (15 points)
Rule 3: Reverse all of the characters in the original password. (10 points)
Rule 4: The enter password should be non case-sensitive. All the letters in new password should be in upper-case. (5 points)
This is what is should look like:
My code:
CODE:
Right now I'm not worried about the efficiency of the code (i.e. simplifying code into fewer lines). The problem I am having is the locating and replacing of the vowels. When running the program the code will replace all of the numbers with "Z", reverse the string, and make all letters uppercase. When it comes to locating the vowels, the program squares the number it goes through the string by the number of letters that it contains. I don't know why it does this.
when the string contains more then 1 vowel the first time it goes through it replaces all vowels with 1, then goes through again and replaces all vowels with 2, and goes through again repalcing all vowels with 9. These are all then combined into one string.
The research I have done has only turned up how to replace vowels with one thing (i.e. all vowels become "*")

I am having trouble with my code for Guess my number. I am definitely amatuer. Yes it is a homework assignment. No I am not asking you to do it for me. But I am stuck.Your GUI program is a game to be played by the user. See Screen Shot on Screen Shot Tab..A new employee is working on a classified mission and the program will randomly pick an expected profit to be guessed by the user.The program must randomly select an number within the range of 1 to 900.Do NOT use a 'Start Game' button to generate the rand number. Generate a rand number when the GUI is loaded.
1. Create a form that displays the rules of the game on a label.
2. Create a textbox for the user to input the guess and also a 'guess' button.
3. If the user is outside the given range, provide a proper message (<1 Is not a valid guess or >900 is not a valid guess)and clear the guess.
4. When a user has a valid guess, display a proper message (either too high or too low) and tell the user to guess again.
5. With a correct guess, display a proper message and change the form's background color to red and disable the guess textbox.
6. Create a reset button that allows the user to play the another game with a new random number.
7. Create a show me button that displays the number and does not generate another random number (allow the current game to continue).
8. Create a exit button to exit the program.
9. Ensure that you include error checking to prevent a user guess that is out of the given range and for any non-numeric characters.
10. Create a single Help menu item that launches a message box that displays valuable and meaningful information for the program and usage.
11. Create a label that tracks the guess count per game. Each time a new number is generated, start the guess count at 0.
12. Create a max guess limit set to 5 and use a progress bar to track the progress to approach the limit.
13. After each valid guess (1-900), clear the guess and update a label/textbox that displays all of the previous guesses up to 5 entries.
Here is my code so far. I have been working on one point at a time and then testing it. I have not even made it to numbers 11 - 13. I am not getting actual errors. Instead of my reset button clearing all fields at once I am having to click it more than once. Instead of displaying messages per scenario the message label is staying on either input a number or your number is too low. My Answer is not displaying when Show answer is clicked-perhaps my answer coding is wrong? [code]

I have an field, Address2, which is optional. Thus if it is null, no validation rules apply. However, if a value exists, its length cannot be greater that 255 characters.
I have been toying with:
<StringLengthValidator(0, RangeBoundaryType.Inclusive, 255, RangeBoundaryType.Inclusive, MessageTemplate:="Address 2 can be between 0 and 255 characters in length.", Ruleset:="MyRules")> _
But if it's not present, I still get an error.

On one side, in Vb.Net when you add an event handler to an object the created method is named: <NameOfTheObject>_<NameOfTheMethod>.As I like to have consistent syntax I always follow this rule when creating event handlers by hand.On the other side when I create private variables I prefix them with m_ as this is a common thing used by the community, in C# people use to put _ at the beginning of a variable but this is no CLS compliant.

is there a way to validate controls on a form, where the validation rules themselves are stored in a database table?My problem is my application is used to submit forms to mulitple government agenices both local and state level. Every entity seems to have there own rules about what needs to be in what location. i would like to not have to code all of the various rules for all the different fields. My thought was to store them in a database table and then perform validation based on rule table lookups...however I would like to use the .NET validation controls.

I am using ASP.NET 3.5 and C#.On my page I need to have a Text box that must not be visible to the user but it MUST be there when you look at the Page Source, reason being, another program called Eloqua will be looking at the page source and it must get the value of that text box.The value of that text box will be populated based on what the user selects.Thus, i cant set the text box propery to Visible = False because then it will not be in the source html and i cant set the Enabled = False because i do not want the user to see the text box.Is there some property I can use to make this text box hidden to the user but still visible in the page source?

So, I was making shortcuts for a text editor I made. The first 3, that I originally included were control-b control-i and control-u for the bold italics and underline. That worked fine. Recently, I added control-s and control-o for save and open. I don't know why, but once I press control-s or control-o once, the control key seems to stay "pressed", so whenever I press just b, u, i, s, or o, they activate the commands. Here's my

I'm making a text editor. I found that control-i automatically adds some sort of space block into the textbox by default; like how control-z undoes even if I don't code. I want to use control-i for making italics text; but the spaces are interfereing. It's one big block of spaces.

I am currently developing a service using the SharePoint 2010 Client Object Model to programmatically upload Excel worksheets to a Drop Off Library and then set the properties on the file. This process is working well. However, the Drop Off Library is governed by Content Organizer Rules that aren't being applied to the uploaded file. I have examined every property I thought I could have missed: [code] What's most frustrating is that if I edit the document properties using the Web UI and check it back in without making any changes, the file is moved to its final location. What might I have overlooked that is preventing Content Organizer Rules from being applied to newly uploaded files when using SP2010 COM?

I'm using My.Settings to store some text information which will be displayed to the user under certain conditions. What I'd like to know is whether part of the text (not all of it) can be formatted in bold?
The reason I'm storing in My.Settings is because it can be customized but not to the extent where I need to store it in a database. And while I'm at it, is it possible to format parts of MessageBox text and labels in bold, or is this an all or not at all situation i.e. changing the font property?

I am having trouble making a function that reorders the text put into a textbox. I then have to get that reordered data and put it into a list box.
Basically, 2 words separated by a comma are entered into a text box (say Wash, Car is put into the text box), then I need to get a function that reorders that string and be able to put in into a listbox that shows Car Wash. So it gets the word after the comma first, then gets the word before the comma. It should do this with every string.
Need to use a function for this.
Right now I really just have
Dim Word As String
Word = textbox1.text
'Then the function to reorder the name and return the reordered name will go right here
What this is suppose to do?
- Example, some puts Wash, Car into textbox 1. List Box 1 will display Wash Car.
- Basic, Visual in textbox1, list box 1 will display Visual basic
