This though returns numbers like "500" or "9" as valid. Why does it do this? Do I have to set the IP address version, if so how would I do this?
I would like to check the format of a string value (contained in a variable) before using it in further code.
- It must be 8 characters in length (no more, no less)
- It must be in the following format: 2 digits + 1 letter + 5 digits
I imagine the VB.NET code would be something along the lines of:If CStr(strMediaNum) (...not in the form [2 digits + 1 letter + 5 digits]...) Or (...datalength not equal to eight characters...) Then Exit Sub EndIf

View 2 RepliesI need to validate user input in some fields, where these are defining how to show time in some views.
Requirements: Time format must be expressed in Microsoft .NET way (check this MSDN Library article if you want to learn more about framework's date and time formatting: [URL]. Keep in mind I'm looking to validate the format instead of an actual time string.
For example, user may input:
HH:mm
hh:mm
ss
hh:ss
mm:ss
... and so on.
In fact, it should validate from the shortest to longest time format available. Another point is I need to do it in client-side using JavaScript. In other words, any given regular expression by you should work in browsers JavaScript regular expressions' engine. I can't use ASP.NET validation engine, or any other. Because of project's requirements, I need to avoid that.
I would like to easily validate dates in this format, e.g., 31-JUL-2010 and only this format. Any other format should be considered invalid.

I am trying to build a coordinates system but am having trouble with how to.. What I have sofar is a textbox that allows the user to enter a length. This length is user defined but never smaller then 610 in length since this is the minimum unit size we use to build timber frames. The overall length of a timber frame is infinite (well not really, but it is for what I want) the timber frame has beams every 610mm set apart from each other (this is a legal requirement) so I want my vb.net to set coordinates for each beam at intervals of 610 then write that coordinates system to a text based *.SCR file

I have a issue with my DataGridView. It's bound to a DataTable at form load. I have a sub wich handles data recieved from a serialport. Inside that sub I'm adding a row to my datatable. That works fine, but to make the row visible in my datagridview, I have to either click on the row, resize the form so that the DGV dissapears and then appears again, manually call DataGridView.refresh or something like that. Why isn't the DataGridView automatically redrawn when a row is added inside a sub like that? One solution is to add a timer where DataGridView.refresh is executed every second, but it doesn't seem like a good idea
