Hello,
I'm new to building applications that will run on servers and I would ike to know if anyone could help me.
I'm looking to build an application that will keep on running even after the administrator has logged off of the system. (Ie SQL Server, IIS) I've already made it so that the application will show up in the system tray.
Would anyone have any suggestions or be able to point me in a direction?
Thank you,

You need to create a Windows Service. If you're using .Net, it should be quite simple. If you're using VB6, use C++!

Is there a way to zero out all variables in a user defined type all at once. I don't want to write a function to set the structure variables to 0.
'Decl
Private m_tBigStruct as Big_Type
----Some Module---
Type Big_Type
.LnAmt as double
.pmtstream(1 to 360) as Pmt_Type
'a bunch more variables go here
end Type
I want to wack the values in m_tbigstruct with one line of code.

Here is some code that may help if you would like to unzip files in Vb.Net. The NZipLib.dll is required.
Public Function UnZipFile(ByVal FileName As String, ByVal DirName As String) As String
Dim s As ZipInputStream = New ZipInputStream(File.OpenRead(FileName))
Dim theEnTry As ZipEntry
Dim filePath As String = Path.GetFileNameWithoutExtension(FileName)
theEnTry = s.GetNextEntry()
Dim di As New DirectoryInfo(DirName & filePath)
If Not di.Exists Then
di.Create()
End If
Dim count As Long
While Not (theEnTry Is Nothing)
Dim fs As FileStream = File.Create(DirName & filePath & "\" & theEnTry.Name)
Dim nBytes As Integer
Dim data() As Byte = New Byte(theEnTry.Size) {}
Try
nBytes = s.ReadByte()
count = 1
While nBytes <> -1 Or count < (theEnTry.Size - 1)
fs.WriteByte(nBytes)
nBytes = s.ReadByte()
count = count + 1
End While
Catch ex As Exception
MsgBox(ex.ToString)
End Try
fs.Close()
theEnTry = s.GetNextEntry()
End While
s.Close()
End Function
Hope this helps you.

Hi!
I did a installer using the Visual Basic Installer but after instalation, only the one who installed the application can use the program (installed). I dont know if I have to change something on the vb project (used by Visual Basic Installer) or change the instaler's code.
Could you help me?
Thanks

This sounds more like a permissions problem on the target computer than a programming or installation problem. What OS is it installing to?
Win2K has caused me some headaches after installing even commercial MS products. Only an Admin can install them, but after I did an installation for the user and had the owner log in, the app went away. Locating the program was no problem, but I had to manually change the permissions for each app to allow users to open them.

Thank you Roger Wright!
I'm using win2k. I'm in doubt of what place I have to write the key (used by Visual Basic Installer) on the register. Using Visual Basic Installer you have some options like that, and in addition I dont know if version of win2k I use have some restriction about that.
|
|
|
|
|
In Win2K only local administrators can modify the Registry. Whoever installs the app will have to have admin priveleges, then after installing will have to set permissions for users manually. I'm sure there's an easier way, but I haven't found it.

I have a Ocx component .. how can I create a Array of this component ?
|
|
|
|
|
You just declare an array of the type of your OCX.
For instance :
Private m_MyActiveXArray(size_of_your_array) As MyOCXLib.MyActiveX

Hi, I using a Ocx component to make Sockets UDP Conections
I need to pass any CONSTANT values to OCX to start conection ..
SOCK_STREAM .. etc ..
What Library I need to include ?? How can I do this Using VB .NET
Tks

You may just need to include the correct namespace for your project. Try adding System.Net.Sockets to gain access to socket methods and properties within your application directly.

Does Anyone know what is the equivalent c++ command "continue" in VB?
|
|
|
|
|
There isn't one. Either restructure the logic inside the loop, or use a label and Goto.

How can I use sockets in VB ..
I am trying to use WinSock.ocx but appear the follow message when I try to put the component in the Frame
"You do not have a license to use this ActiveX Control"
I am using Visual Studio .net Beta Version
are there another free component that can I use to send UDP packages ?
|
|
|
|
|
If you are using .NET, then you should check out the .NET Framework for socket classes, rhater than using the OCX.

One method is to create pictures that can be used as the background pic of your forms. I recently used this for developing a software where the clients demanded a slight fancy look. Also instead of the VB buttons, I used image controls. The button movement was implemted using a combination of mousedown and mouse up events. For this you will need an up image and a down image of the button. BTW, I think bmp format is compulsory.
