Big Panel Visible And Not Visible Based On Selections Made By User
Jan 28, 2009I've got a panel - that's in a group box. All of this - with lots of other textboxes on labels - is in another panel (the big panel).I make the big panel visible and not visible based on selections made by the user.This small panel - that's in the group box. I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!

Jumping Between Forms - Making A Form Visible And Not Visible
Jul 17, 2009I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.
Make Several PictureBox Images Randomly Visible = False And Then Back To Visible = True Giving The Appearance Of Flashing Or Blinking Images?
Jun 28, 2010I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

View 3 RepliesFormat A TextBox Like A MaskedTextBox?
Sep 21, 2011After experimenting around with DevExpress controls and adding them to my form, Custom mask do not seem to work on the MaskedTextBox. If I place a custom mask and debug, I get a null reference exception.
It seems to be the maskedTextBox's mask property that is doing this. I have tried setting the mask through design and by code. However, neither way works.
My question is, is it possible to use a TextBox as a maskedTextbox? To be able to format it? I need the user to enter in hours, minutes, seconds like hh:mm:ss or 00:00:00.
Here's the error I get:
"NullReferenceException was unhandled. Object reference not set to an instance of an object."

MaskedTextBox Control Validation?
Apr 3, 2009I am trying to find a way to validate my MaskedTextBox control called mskDate which is a short date property. I need to determine whether the user entered a date in the MaskedTextBox control. I cannot use the Not IsDate function because what happens if the user does not make an entry, then the Not IsDate would not work because the user is not required to enter a date. What happens if the user only enters 03/? This would not be considered a date, but a valid date is required. I tried using the substring to see if an entry has been made but it does not work because of the / / format.

May 18, 2006I am trying to find a way to adjust the height of a MaskedTextBox. The height seems to depend only on the font size.

Set Maskedtextbox To A Currency Format?
Sep 16, 2007Does anyone know how to set the maskedtextbox to a currency format that actually works? I have set the mask to $999,999.00 but the user input looks like this 120,0 instead of this 12.00. It seems like the maskedtextbox would be able to handle this type of input without using the keypress events to alter the text.

Validating Zip Code In MaskedTextBox
Mar 24, 2011I have a MaskedTextBox set to validate Zip Codes.
I set up my code to allow the user to enter either 5 numbers since most people like me don't know the last four of their zip codes.
The plan here is to allow the user to either enter 5 numbers or 9 numbers. The numbers cannot be less then 5 or more then 9.
If the user does not enter the numbers they cannot leave the field.
This is just a practice project.
This is the code I have written.
I have chaged this code multiple times for about an hour and cannot figure out what I am doing wwrong.
take a look:

Now, I cannot get if the MaskedTextBox is string.empty because it is not an empty. I cannot use "If MaskedTexBox.Text = "__/__/____" then " condition also because It never captured. If I used MaskTextBox.MaskFull = false, It gives an error on creating form. So I came up with an idea that would subtitute to TextChanged Event.

Calculator - MaskedTextBox Format Error
Dec 2, 2011I am working on a mortgage payment calculator that has three user input textboxes (amount, interest, term). The interest input is a MaskedTextBox masked to (00.0). The issue I have is that if the MaskedTextBox is has no user input when the calculate button is selected then I get the error "FormatException was not handled" "Input string was not in the correct format", I highlighted the section in the code below. I'm quite positive the error stems from the MasketTextBox mask of 00.0, the decimal I believe causes the issue when no other data is entered.

Custom Mask Language For MaskedTextBox?
Sep 16, 2010I 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?
Event Calling Mismatch In MaskedTextBox?
Jul 22, 2010I have built a customized control inheriting the maskedtextbox in VB.NET. But i face some issues in the calling of events. For eg. if there is control named : Control1 and in the designer file i set the text property of the same to some value (Control1.Text = "test"), then the text change property is called. But i need to call the event only when the text property is changed during the run time (not while initializing in the designer file). Is there anyway to trigger the text change event only when the text property
is changed in files other than the designer one.

Highlight Numeric Characters In A Maskedtextbox?
Apr 14, 2011I am using a masked text box to allow users to enter a serial number. The problem is that this serial number has to be communicated over the phone and people seem to be having trouble differentiating between O and 0 and I and 1.
I thought that a good solution to this might be some way of highlighting which characters in the textbox were numeric characters (as opposed to alphabetic characters). Obviously there is no way to do this without using a richtextbox and then I lose the masking ability. Highlight numeric characters in a maskedtextbox?
