Format A TextBox Like A MaskedTextBox?
Sep 21, 2011
After 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."

I am creating a WinForms application using VS.NET 2005, VB.NET, and SQL Server 2000. My problem is the MaskedTextBox control. I can successfully insert the value in an SQL Server table column as smalldate such as 3/17/2009, but it displays as 31/72/009.
I tried the following with no success:mskLastPayment.Text = Format(rdr!LastPayment).ToString("MM/dd/yyyy")mskLastPayment.Text = rdr!LastPayment.ToString("MM/dd/yyyy")mskLastPayment.Text = CType(rdr!LastPayment.ToString(), DateTime).ToShortDateString

Does 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.

I 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.

In COBOL, I read a value (a currency amount with 2 decimal places, for example) via a picture clause (and a screen section, of course), like:
WORKING-STORAGE SECTION.
01
VALUE-TO-READ PIC ZZZ,ZZ9.99.
...
[Code]....
The tricky part here is, whenever the decimal sign key is pressed, the input procedure understands that the following number is to be displayed to the right of the decimal point (not left).
Now, I'm trying to do this in VB. Unfortunately, my all attempts failed with MaskedTextBox.
Do I have to hardcode this procedure in my program, or is there an easier way to get around this?

I have an officecharge textbox in which I specify how much I'm charging the customer for a specific service. If the user changes the officecharge value for that customer I would like to keep track of the previous value to then compare
it to the new value to then set a boolean variable true or false accordingly. I would like to fire/trigger this segment of code everytime the user leaves the OfficeChargeTextBox (after it loses focus) so that it can compare the final value entered with the previous value and then decide what to do based on whatever login.applies from that point forward.[code...]

yeah im very far with the project right now just a day or two probably of completely finish it, but im so far that itll break alot of things if i change a textbox i have for a maskedtextbox, besides there are some things that the normal textbox does a bit differently than maskedtextbox, ive searched around the net and found nothing about this in vb express, probably because everyone uses maskedtextboxes instead xD

I have the following:
MakeCmd$ = "SY" & 0 & (size% + 1) & Data$ & chk%.
This creates SY0387142, this relates to, SY,0,3,87,142.
I want put this in a textbox in hex format. I have tried various methods, such as
'CmdData1.Text = CmdData1.Text + Format(Hex$(Asc(Mid$(CmdStr$, Count%, 1))), "0#") + " "
But this does not work correctly.

Also, how do I set a textbox to be fixed with two decimal places? On VB6 I could do this in properties, but I can't find an option ni Visual Basic Express 2008.
