Check For 3 Characters In Text Box, Pad Left With Zeros If Not Enough
Jul 14, 2009
Basically I need to make an if statement that checks the number of characters entered in a text box and pads left with 0's if there is not 3 characters entered.
Also, if letters are entered, I'd like it to produce an error message, or just not accept letters at all.
Is there someone who has done something similar in the past that might be able to help me format this textbox?

I am trying to figure out how to make a .SubString get the characters from right to left not left to right.Say if a user enters 123456789 in text box 1 and I use textbox1.text.SubString(0,2) it will display 12. But, I want it to get 89.I do not want it to get 98, but 89. I tried textbox.text.substring (0, -2) but that just gives an error.So if Gold is entered it gets ld

I have a field that needs to be 10byts long. However, if the number does not use all 10 bytes, then it will need to have zeroes in front of it.say you have a Check number of 12345, well in the text file it would need to show up as : 0000012345..This is the code I'm currently using but when I open the text the other 5 remaining bytes are just spaces.

I have a lot of really long strings that I want to test. Is it possible to use the CASE statement and compare it to the first 25 characters of the string to get a match?

For years I never had trouble with this String. Format function until today when I got a value longer than 0 characters and the function returned all the characters in the string instead of just ten. Now sometimes I get less than ten characters so I can't use the substring with out getting an error. I can try the left function but I was hoping there was a solution with the Format function.

When populating the data into a date masked text box for display, I am not getting the zeros in front of the month and day resulting in the date 07/02/1974 displaying as 72/19/74.
How do I insure the month and day have the correct format before the masked tb gets filled. The data type in SQL is small date and displays in the table as 1974-07-02 vS2008 / SQL2008

I have a process which grabs the birthdate and from a data table and display them in a masked text box for viewing and editing However when pushing the data into the textbox any preceding zeros get removed For example 05/05/2005 would display as 55/20/05__
The masked Text box is set up as 00/00/0000 The line which assigns the code is:
MaskedTextBox.Text = Format(DataTable(0)("DOB"), "MM/dd/yyyy").ToString
To date I have tried the following:

My project uses a lot of System.Drawing.Image commands and sometimes it gives me the out of memory error. I was wondering if there's a way to check remaining memory left and to halt a process if there isn't enough? Or if there is a more practical solution?

I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time.Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

is there a way to check if a string contains characters other than numeric? ive used isnumeric quite a bit and its pretty usefull, but cant find a way to check for text in a string. Having searched around theres a few ways of doing it slowly that ive found using an array of letters and a loop / instring, but thats much more hassle than checking for numbers, so strikes me there must be a way.

someString.Contains("[A-Z].") but this didn't return me what I wanted.

Here's my question, I have a DateTime "12/15/1899 12:00" that I need to just get the "12" part for a string. Basically what I need is 2 characters to the left of the ":" I'm presumming that due to the fact that i'm wanting 2 characters that the function will automatically put a zero in front of the 1 if it was 1:00. How do I do this?

Perhaps I am using the wrong Keywords when I am searching..... I want to use a Masked TextBox for a Money entry point on my Form. The Mask is $000.00, the problem I have is if the user wants to enter a value $9.99 (999), he gets $999.00. I have tried the TextAlign Right, that just moves the text to the right side. The RightToLeft just means that it the entry then looks like __$999 How can I make it Fill from Right to Left? Or is there a bertter control to use? I like the masked text box idea because I can eliminate the literals for calculations that I will be doing.

I wish that visual studio 2010 would have more support for rtl. this support would be in two places: include an option for visual cursor movement like in MS Word. when switching a form to rtl the anchor points and the alignments are all reversed. Thy should be logical meaning when I anchor a text box to the right it should anchor to the right and not the left. will these are my only two wishes for now.
