temp = rtb1.SelCharOffset
Dim SelectionStart As String
Dim SelectionEnd As String
Dim selectedExp As String
Select Case KeyCode
Case vbKeyUp
rtb1.SelFontSize = SupEnt / 3 * 2
rtb1.SelCharOffset = temp + 100
rtb1.SelColor = vbRed
KeyCode = 0
Case vbKeyDown
rtb1.SelFontSize = SupEnt / 3 * 2
rtb1.SelCharOffset = temp - 100
rtb1.SelColor = vbGreen

You just want to cripple this check, kinda like this?
Private Shared Function IsRegExpired() As Boolean
Return False
End Function
These kinds of tests are usually built in such a way that bypassing them ranges from hard to impossible.

hi,
i am new developer in vb.net.
i know db connect with local machine.
actually my project database is share with multiusers.
so how can set remote(LAN) database connection in vb.net?
please help for me!!!!

You put the database back end (ie: the file with the tables in it) on a server/shared location, and you address it like this:
\\servername\sharename\databasename.mdb
|
|
|
|
|
You can put your database file to your Server and connectionstring must have the name of Server,database name and database password.

Hi there - I am a newbie to the world of programming and have come across a huge stumbling block that is driving me wild.
I am trying to create an application that will get a list of all the xml files in a given directory, read through the contents of the xml files (they are all of identical format in terms of node/element structure) and populate a datagridview with the contents.
I have created an array of xml files and have been successful in binding one of the xml files to the dataset but I cant get it to iterate through the entire array. If I carry out the same task but output the contents of the xml file to a listbox it works successfully.
Can anybody help?
The problem code is:
Public Sub xmlReader2(ByVal dirPath As String)
Dim xmlfile As XmlReader
xmlfile = XmlTextReader.Create(dirPath)
Dim ds As New DataSet
ds.ReadXml(xmlfile)
DataGridView1.DataSource = ds.Tables(0)
End Sub
This sub is called by another sub which is iterating through the array. Like I say, I can output the information to a listbox so I presume the problem must be with the above code.
Hope some clever person can guide me in the right direction.
Thanks

I would suggest if you want long term success, you should abandon this task and focus on learning some basics first.

Hey im in the process of creating a railroute manager with VB as Front End and SQL Server as the Backend. It has a server and 3client layout (LAN). I have programs ready to be deployed asper the privledge levels on the server and the clients
And the doubts is How do I logically connect the systems and make my DBrelations on the server dynamic with client actions? I have heard that Socket Programming is something about it.
Im waiting for a response,......

Your question is so general that it borders on unanswerable. Noone can give you a clear answer because your asking about how you should design your application, but provided no details about it that would drive an appropriate answer.
Also, the various parts of your question have nothing to do with each other! "Dynmaic relations" does imply any differences between how your data model would react to a users privilege level. On top of that, I fail to see how "Socket Programming" would affect how your data model is designed.

Is this homework, or has some country actually outsourced such software to people who don't know what they are doing ? Is there any chance that your bugs will kill people when two trains collide ?

I have been working on a database program with a Access database. I have on one form a datagrid and it has "Employee Table" table on it. Now what I want to happen is if you click on a row and click "Open" button (btnOpen" it fills the information to another form with text boxes like "TxtAdd1" (Address) and so on.
Also, I have a save button on the form with the text boxes (Save Form) and what I want is to be able to save the information in the text boxes as a new employee in Employee Table, but if the employee ID is same as already in the database table, it will say message "This employee ID already exists, would you like to overwrite current employees information?" (Yes or no)
Any help would be appreciated. I am trying to make this so I don't have to use databound items on text boxesThanks in advance.
In the end we're all just the same

You need to write code in the button click events of both the buttons. In case of open, get the selected row and fill its data in the textboxes. In case of save button, use classes in OleDB namespace to save data.

Assuming this will be the primary key, it should be auto-incremental or should be generated through code. Why are you letting user create the IDs?

I fixed that, just realised the ID should be an autonumber. Anyway is there a way of adding the information on all the textboxes to the database table as a new user... the txtAdd1 text will be stored in Address 1 cell and so on.
In the end we're all just the same

Create a stored procedure in your database and send the textbox values as parameters or build a query in your code and perform insert/update using Command object.

u should use command builder to save or update which will generate command dynamically insert for new and updated for existance.

Obviously you need to step through and work out why m is not -1 when you want it to be.

I think you actually want to do a replace rather than remove

You can't, unless you do an indeterminate one. Of course, it also needs to run in another thread.
