Ummm, this has precisely what to do with VB.NET? Are you sure you're not looking for the SQL Forum[^]?

Hi there,
Ive been working on a simple VB project for work now for a few months on and off. Its a very simple project, just opening and closing forms, nothing complicated as i have very little experience with programming. Its more for presentations sake than anythin functional.
Its due pretty soon, and of course, somethings gone wrong.
When I build the solution, i get three errors.
1. Could not copy temporary files to the output directory.
2. The file 'Name.exe' cannot be copied to the run directory. The process cannot access the file because it is being used by another process.
3. The file 'Name.pdb' cannot be copied to the run directory. The process cannot access the file because it is being used by another process.
There is nothing else running on the computer at the moment and i cant think of anythin i could have done for this to happen.
If anyone could help me out with this, i would greatly appreciated it
Thanks for your time,
Peter

Has a reboot fixed your issue? Obviously something is locking your build files (Name.Exe & .Pdb) If that does not work try chaning your build folder. Project->Properties Click the Build Tab. In the output section Change "Output Path"

how to create login page in vb.net?
hello
|
|
|
|
|
Well, you can use a template login page by selecting Add New Object > Login Form. Or you could create your own using a textbox, then matching the value of the textbox to a password.
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

you can use redirect method after the page check the username and password.
<% bla bla bla<your code="">bla bla
.
.
response.redirect <page_name> %>

hi swathi,
if u are asking the navigation from one winform to another...then do this.
take 2 text boxes (TxtUid, TxtPwd), and a button (BtnSumbit)
Login.vb, Welcome.vb are 2 forms
Private Sub BtnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSubmit.Click
Dim Userid As String
Dim Password As String
Userid = "Max"
Password = "Ruby"
Note: i just hard-coded user id and password here. but u have to change the code according to ur requirement. i mean if u want to validate the user id, and password with Database values then just modify the code accordingly
If Me.TxtUid.Text = Userid And Me.TxtPwd.Text = Password Then
Welcome.Show()
Me.Close()
End If
End Sub
End Class
if u want to access the login form values(user id, password values), then first, u need to set the modifiers property of the text boxes to Public. (by default the modifier for the text boxes are "friend"), then just access the values just assaining the first form name.control name.text = from2.control name.text.
if this is not what u r asking about, then please post ur question in detail.
thanks,
Rahi

i want to use Dijkstra algorithm to find the shortest path.
the node is fix. what i found from other source code is quite advanced where user can DRAW the node and the direction.
for my case, my node is fix and direction is fix, nothing is changing. i just want to find the shortest path, for example A to G, the shortest path is
A -> C -> D -> G. that's all.
i just need the source code to find the shortest path providing i have the matrix done. thx.
i am kind of urgent. thx!

Why does this smell of homework? Google results[^] for "Dijkstra vb". The second link down is an article right here on CP.

That's just telling you it can't find the help to tell you what is wrong. Are you sure your pinvoke signatures are right ?

Are you using VB6 or VB.NET ?

OK - VB6 is crap to start with. There are probably some commercial grids, but I thought people mostly used the flexgrid.

Hi.
I read on microsoft comparison chart that VB express 2005 does not support remote databases which im guessing is that same as shared network database.
is there no other way , perhaps a 3rd party app that can allow this.
Please let me know so i can consider upgrading if need be.
Regards
Robbo

I suspect this means you can't connect to a remote DB within the IDE, I'm sure the end code can run a DB from anywhere.

Hi Christian
I guess without confusing myself, Im wanting to find out if im able to setup a shared network database. so basically i want to create a multiuser app using a centralised MDB Database where multiple users can read and write to the same database.
can you please confirm if this can be done in VB EXPRESS 2005.
Many thanks
Robbo

Yes, you can. Like Christian said, the code you write can interact with the database without any problem. It's just htat the Express Editions of Visual Studio don't supply and Designers that will write any database code for you.
