Halo, may i ask how can i save my answer fault into database after i done division. I am taking the data from textbox(input data) and done the back coding division.
i got a table in a datagrid, i did the whole connection with visual basic, the one to add a database, and now i see my mdb database in datasources and all..
this is my code
vb.net
Public Class InventarioIps
Private Sub InvIPS04_10BindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles InvIPS04_10BindingNavigatorSaveItem.Click
[code].....
I dont know if i have to create the connection to the table in this code so it can update,save,delete my info in the datagrid directly to the database source.?
When i save the info it only shows in the DATABASE thats in the BIN directory not the other one (the main one)...but either way when i close the whole project and open it again it loads the info from the main DATABASE and of course the BIN one changes witout the saved data?
I have added a textbox and a combobox into the form. There are 2 buttons as Add and Remove. Everything works fine here but the problem is after addig/removing (using add/remove button) new items into the combobox, when I close it, the new items added/removed are gone. I need to save the new items added to the combobox during close. I can understand I have to create a Application Setting which will save the new items added to combobox upon closing. But I don't know which code I need to use? Below are the currently used code of this project.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
' This is to add new items to combobox
ComboBox1.Items.Add(TextBox1.Text)
'MsgBox("" & TextBox1.Text & " Successfully Added to Combobox")

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?

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.

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.

I've come across code in a library that I want to use that I have never seen before (probably because I don't use c# all that much) and can't find any documentation on. It doesn't work in VB.NET and I'm not even sure of what it does so that I could go about doing it some different way. The expression is Mask.NullString(str).Length. Can anyone help me out please?
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.
