View 3 RepliesWhen 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 masked textbox formatted as "##:##:##:##". When I send the variables to it if the number is <10 I don't get the leading zero displayed. For example:[code[What I want it to look like is 00:01:02:03, what I get is 00:12:3. I've tried the variables as an integer and a string with no luck.
View 2 RepliesConverting an object .tostring() removes the leading zeros. The object is not a fixed length, so I can't do object.tostring("0000000") where the number of zeros represents the fixed length.
An example object value is "0357" when I convert that object .tostring it becomes "357".
Is there a method for keeping the leading zeros where the length is not known?
In my app. I am using this code block to extract numbers from a string in a TextBox.

How can I get the leading zeros (if there is eny) removed from the number tha has been extracted?.
When using the command TimeOfDay.Now.Hours and TimeOfDay.Now.Minutes, etc... and the time is 09:03 (for example), the output is
93 when it should be 0903
I'm unable to get rid of the leading zeros in my time format. I want it to say 2:30 (two minutes 30 seconds) not like this 00:02:30. Is there a way to do this? DateTineInput1 and DateTimeInput2 are both text boxes. Here's all the code for the time format and duration

Dim timenow As String = Date.Now.Hour & "-" & Date.Now.Minute & "-" & Date.Now.Secondbut if the time is now 03:09:01 - what I have above ouputs 3-9-1
View 2 RepliesI have a textbox on a form that I use just for output (read only). After doing some calculations I display the value in HEX string as feedback to the user like:
txtReg0.text=HEX(Reg0) 'Reg0 is a UInteger previously calculated
This seems to work fine except the textbox only shows all the HEX characters if the first character isn't a zero. Otherwise, it shows less depending on how many zeros are leading.I WANT to show all (eight in this case) the characters regardless.
I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.

View 21 RepliesI am new to VB and I have two detail listviews with one full of items that can be droppedinto the other. I have three groups in Listview1 and I would like different forms to open up based on the group each dropped item belongs to. I was able to open Form2 on drop by adding Form2.Show() at the end of the ListView_DragDrop handler sub, but this opens forevery item and I want different forms to open depending on the ListViewGroup the item belongs to.I set the items and groups in the property windows and not in code; I do not know if this makes a difference. So here is the code I have on Form 1 where the listviews are:Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _

I insert a text box into form1. I move the mouse pointer on top of the text box. I press down on the left mouse button and begin to drag the text box. The problem is when I let go of the mouse button the text box is not dropped. it remain floating around. My only way out of this is to press the escape key which places the text bnox bak to its original location. Thinking that it might be my mouse I tested it in Power point and everything works correctly.
View 2 RepliesI 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.

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 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__
