View 5 RepliesI am trying to verify that I have a valid subnet mask. I have already verified that the string format 255.255.255.0 or whatever 255.255.240.0 converts to a UInt32 but now I need to make sure its actually a subnet mask.
The bits should be split between 1's for the network part and 0's for the host part. It should start with all 1's and end in all 0's if it goes from 1's to 0's then finds any more 1's its an invalid subnet mask.
How would i get a certain text inside a textbox to equal that text space to space or null to space?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Textbox1.Text.StartsWith(Textbox2.Text + " ") And Not String.IsNullOrEmpty(Textbox2.Text) Then
Textbox1.Text = Textbox1.Text.Remove(0, Textbox2.TextLength)
Textbox3.AppendText("a")
End If

My column name has a space in it, nothing I can do about that it comes from a 3rd party provider.My Column name is "Sold Price" I am trying to use a textbox value in place of hard coding the word "Sold Price" because i am trying to write my program to work with a different database that might use "SoldPrice" or "sellingprice" etc.I know when I was hard coding the column name i had to place a "'" or bracket around the name because there was a space i cant seem to quite get it when i use the textbox value.[code]

View 3 RepliesI am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)
I'm trying to write a program that accepts a word and then determinesif the letters in it is in alphabetical order. There will be a message if it is, like with the words almost, imply, abcd and so on. However, if the letters are not in alphabetical order, another message will show.

notice the textbox1.text, it should only accept a double. IF the user inputs letter or whatever characters then the program must prompt a message which reads "input only a number"

For a drop down combo box, if you place 0 as a custom mask, you can enter only numbers. If you place A as the custom mask, you can enter letters and numbers. How can I make it so that you can enter only letters?
View 3 RepliesI'm having trouble getting a masked textbox to properly store a date. I'm using the short date format 00/00/0000 but when I navigate to a record that only has a single digit date it displays incorrectly.eg. 12/01/2008 displays as 12/12/008_Surely there's a fix for this but I'm not finding it.
View 5 RepliesI have been using the following code to find files within a directory with a specific mask, without any problems except windows 7 platforms.
The Folder searched contains five(5) word documents with a .dotx extension
The following mask is being used:
"*.doc", "*.docx", "*.dot", "*.dotx", "*.pdf"
The search returns me ten(10) files as the *.doc mask returns the *.docx files too.
How can I get this to work on old windows platforms as well as Windows 7 with the same mask?

I'm in MS Access 2003. I inherited a form with a text box. The text box has the following input mask. !(900") "000-0000;0; Here are my issues.
1. If the form is opened and I click in the text box at a point that is not leftmost, the cursor may not be placed at the leftmost position. Sometimes, it gets stuck at some point in the displayed mask. If I click in an empty text box, I always want the cursor to be leftmost. How can I create that behavior ?
2. If I get the cursor in the leftmost position of the text box and try to paste in phone numbers in certain formats, some of the input gets chopped off. ex: 555 555 5555, becomes (555) 555-{cursor} 555-555-5555 becomes (555) {cursor} IMHO, these formats are common enough that I would want a mask to accept it. Can I make the mask more general ?
3. What is the meaning of leading !, the double quotes, and the semi-colons?
I am trying to Mask Employee ID, so the user doesn't have to type the entire employee ID number CCETA01. I want them to type only two digit numbers. e.g. 01 to 99...
Here what I did but its not working:I draged from toolbox a Maskedtextbox on the Form and in the textbox progerties I put cce a. The entire number show up on my textbox pretty good but it does not allow me to change the two digit numeric number?
There are a number of textboxes I would like to validate. I first set up the key press events to only allow key entry's of characters which I feel are valid for this location (i.e. numbers and "." for dollar amounts). But in addition to this I would also like to ensure that the user entered something valid using an input mask. This may be a simple question but I couldn't seem to find the answer to it. If I have a input mask of ###.## and the user enters something like 4321.23, would this throw an error and if so, how should I set up my mask large enough so the user is able to enter large amounts.
View 3 RepliesHere is the
Option Strict On
Dim mask As ULong = &HFFFFFFFFUL
Dim result1 As ULong = 20L And mask '//disallows implicit conversions
Dim result2 As ULong = 20L And &HFFFFFFFFUL
If you put that into the IDE with Option Strict On, it will not let you compile because of 'result1'. I'm not sure I understand why. In the 'result2' assignment, I am explicitly saying to use an unsigned long, however it's not giving me any grief.
the Threading.Interlocked class provides; I don't understand, though, why the Add function only offers two overloads: one for Integers, another for Longs. Why not Doubles, or any other numeric type for that matter?Clearly, the intended method for changing a Double is CompareExchange; I am GUESSING this is because modifying a Double is a more complex operation than modifying an Integer.

View 1 RepliesI am creating an application where the user inputs must be restricted. Of course, the MaskedTextBox control provides the basic functionality for this, allowing me to set up a fixed input-string length, include literals if desired, etc. However, in some instances the available input-character types (digits, alphanumeric, etc.) are not sufficient to provide the restriction I require.
For example, in one field the user enters a hexadecimal number, i.e., composed of only characters [0-9][A-F], but there is no option in the default masking language for that. It would be nice to be able to add a couple masking elements, such as H and h for required and optional hex digit respectively. For now, I just check the Text contents of the MaskedTextBox after each TextChanged event and warn the user/remove the offending character(s), but I would prefer to be able to customize the Mask.
Is there any straightforward (or even not straightforward) way to accomplish this? For example, by creating a custom MaskedTextProvider? If so, how would I go about it?
I have a need to apply a mask to a string programmatically and not through any type of Masked Edit Control. So for example a mask of (###) ###-#### would need to be applied to a string such as 5551234567 to create (555) 123-4567.
