Custom Mask Language For MaskedTextBox?
Sep 16, 2010
I 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?

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?

In my winform app in VB.NET I want to use the localization option. But i have a few questions/problems. I'm using a menu strip to select an other language. But it seems that is doesn't change my menustip text to my selected language. It does change my labels, buttons, and textboxes but menu strips don't seem to change when I choose another language. Also is it possible to get those resx files such as MyForm.fr-FR.resx compiled so it isn't an external file outside my app? Or to get those files in an Language folder at the same location of my app, so i don't have all those fr-FR & nl-Nl folders in the same location as my program?

I have multilingual application that was done in VB2005.We recently had a request to translate the application to Arabic (Egypt), so I have been happily running through all of the forms and changing the layout for Right to Left format.I have 2 forms that are problematic though.On one form, whenever I select Arabic (Egypt), it will automatically switch the selection to Arabic (Saudi Arabia) and try to add an ar-SA resx file.On the other problematic form, if I choose Arabic (Egypt), the IDE will automatically select Chinese (People's Republic of China), then copy the contents of my ar-EG resx file into the zh-CN file, overwriting all of our Chinese translations and layout changes with the Arabic ones.

I'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.

I 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.

Here 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.

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?

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.

How can I convert a subnetmask into binary, so I'll end up with 32 digits? I can convert it into Binary, using Convert.ToString(Long-to-convert, 2). But a subnetmask of 255.255.255.0 returns(it returns it without the spaces though):
1111 1111 1111 1111 1111 1111 0
When I want it to be:
1111 1111 1111 1111 1111 1111 0000 0000

I am using VB 2008 & drawimage function to copy image A to Image B. My problem is image A has many different colored patches on it and I only want to copy the ones that have a certain RGB value. I was going to set the masking color to the RGB value but remembered that defines the color to ignore - Im interested in the opposite.
I know I could loop through all the pixels and check its color, but its way slow and Im hoping theres something better?

how to create an 'Access-like' input mask for hastening date data entry.
Using C Pearson's much quoted code I've modified it as such:
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
Dim DateStr As String[code]....
Note: I'm aware that most of the time I'm simply re-typing the original code - it was a learning experiencing and I also realised that the different American and Australian date formatting was less of a programming issue due to the systems being set up differently in the first place.My issue is having run tests using only 4 digit entry, all types of digit entry, with and without DateValue on the final DateStr, changing the cell format to text, to general, to date - always results in a code like "8811" (i.e. 08/08/2011) being changed into 01/01/1924 (approximately).
At first I assumed the use of "DateValue" in assigning the final .Formula value was forcing this conversion. However, with or without DateValue it still seems to read the figure as a DateValue and convert it as such.I'm sure it has to be something elemental that I'm missing given the scores of people I alone have seen on boards reading C Pearson's code and not coming up with another peep.
