----------------------------------------------------------------

It's very rude to post the same question 4 times! Don't!
Try here[^] for a start on DataSet.Merge.

i want to this in case the user erease that file i don't want the program to run

Are you getting this Continue because your running a debug version of your code in the debugger? Try running a Release compiled version outside the development environment. Also, are you trying to handle specific exceptions in your try/catch block? Just use a catch block like this:
Try
...some code that might fail...
Catch ex As Exception
...exception handling code...
Finally
...If you need to run code that must run in all cases...
End Try

not working....i think when i try to call a reference not exist it not look to the try catch...
Try
Dim any_name As New reference1.class1
Catch ex As Exception
MessageBox.Show("error")
End Try
when the reference1 is not aviliable it gives me the default error, not my custom error on the catch

I don't think your going to be able to do what you want. When the reference is being bound to the .DLL, the file is missing? This would be a catastrophics failure (I think!)you can not catch.
I take it this is part of a copy protection scheme?

i think i found some solution, if i made my call into a sub, then i call that sub between try and catch  
|
|

Apparently, I had my head somewhere it should not have been.
I think you looking at this:
Dim myFunction As myNamespace.myClass
Try
myFunction(myParameters)
Catch
' Call failed code goes here...
End Try

Hi,
1. How can I sort a DataTable?
2. After sorting the dataTable, How can I bind this to
an object like ComboBox?
Thanks
Mark

You don't sort the DataTable object, you sort on a View of the table, then bind your control to the DataView, not the table. Check out the docs here[^].
One method of doing this:
Dim myDataView As DataView = myDataset.Tables("Customers").DefaultView
myDataView.Sort = "LastName, FirstName"
myControl.DataSource = myDataView

How to Merge two datasets

HI
I Have created a gui for netsend but would like to know how to add an
active directory listing instead of typing the pc or ip address
in the tree listing
thanking you in advance
|
|
|
|
|
You would have to search for a list of machine or user names using the System.DirectoryServices namespace. You'll be using teh DirectorySearcher and DirectoryEntry to return a list of entires and the details on each entry.
For the docs, start here on MSDN[^].

If I use a reference to a DLL in my vb6 app, the PDW finds it out and adds it to the Setup.exe or something like that.
In VB.net, I found out that we can create a deployment project manually.;)
Does it in any way find out the dependencies automatically? If not, how do we know on what files our application is dependent on? If we know can we add the dependencies...
For Example: If i refer to bitmaps and other files on my PC in my vb.net app, how do I use the Deployment Project to put the pieces together for deployment?
I am sorry I may keep you busy for SOME time!

It does find the dependancies, but not always. Any project that you add manually, you have to supply the dependancies for. This is for dependant .DLL's and .OCX files ONLY! Bitmaps will NOT be included automatically.
If you have files that you need to add, like .BMP's, .JPG's, ..., just open the setup project's 'File System on Target Machine' folder, then the 'Application Folder' on the left pane, and drag and drop the files and folders you need into the right pane. This will put the files and folders into your applications Program Files folder.

I know that sounds really stupid. all you are supposed to do is type:
Unload me And it will unload. Well I have done that but the timers on that form keep going and lead to the ultimate glitch in my program... HELP ME PLEASE! I have asked for assistance from my Computers teacher and he is stumped.
"My Code has fallen and can't get up"
|
|
|
|
|
By any chance, is Form1 the only form in your project? Maybe that is it...
Happy Programming and God Bless!

Sad to say. Its not my only level, I have 20 forms for levels in my game, 6 minigames, and about 8 other ones.
|
|
|
|
|
Make sure the timers are stopped before you unload the form.
Timer1.Enabled = False

That does not seem to work I have about 12 timers 1 is causing me problems..
If world(charlc).Tag = "testchar" Then
MsgBox ("You beat the level!")
isenemyshooting.Enabled = False
leveltime.Enabled = False
bullet.Enabled = False
enemy.Enabled = False
enemyshooter.Enabled = False
score = score + Timerlevel
scores.Caption = score
Timerlevel = -1
greencircles.Caption = Life
level2.Show
level1.Hide
Unload Me
End If
All of my timers have been disabled. So im Completely confused. Help me please! (NOTE: THIS IS UNDER the Leveltime timer.)
My Code Has Fallen and can't Get up

If your form unloads then mysteriously reloads itself, it's because something has a reference to it, like a timer you forgot about (Tick callback), or another piece of code in another form is calling a method on your form.
