I am making a simple timer but I seem to be having some troubles formatting the time. What I have done is split up the hours, minutes, and seconds into integers. The problem is, I do not want my minutes and seconds to be 1:1 for 1 minute and 1 second. Instead I would like it to be formatted mm:ss.What command is used to format and integer to add a preceding 0 or not?
View 4 RepliesHow can i format a double number to be like a integer?

i want to 12.34 to be rounded and displayed like 12 not 12.0.
because when i do String.Format("{0:n0}", 12.34) the number will be displayed as 12.0

View 2 Repliesi'm looking for a VB code to format integer into 5 digits and then after that auto increments like (00001 , 00002, 00003) And they are used in a text box field.
Scenario Example : When the user clicks on Add New Record. The empty id text box field will automatically insert a number 00001 on the textbox and if there user wants to add another record the number goes 00002 and so on.
I'm writing a timer application, and obviously, I'm using integers to track the time. I need to convert the integer to a time format, for display. I've tried the .ToString method, which didn't work.

I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?

After the conversion, the code look like this:

Also FProducts.Serial_number, 0).ToDictionary doesn't work.

I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:
Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)

I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?
