Has anyone out there developed an enhanced console class for VB.Net

What I am specifically needing is a ClearScreen and the ability to cut and paste to the clipboard from inside a console mode app.

I also would like a method to put shutdown code in when the user closes the console mode app from the upper right hand X.

In the good old days console mode apps automatically made use of ANSI.SYS escape sequence.

Can VB.Net console class be enable to use these sequences

I have read that the console mode class was made such that you can not derive a new class from it and add additional methods.

VB 6 Project Limit

MSDN says there is a limit of 32,000 unique identifiers, variable names, module names, etc. in a VB 6.0 project. Is there any way to tell how many I have in a project, other than going in and actually trying to count them manually?

Thanks

database stored procedures vb and much confusion

Here's my problem.

I wrote a bunch of stored procedures on a sybase database and I want to be able to trigger them from vb.

How do I connect to the database through vb, and how do I call a stored procedure passing in variables? I'm doing this all in a module, so no visual cover. Any ideas? Confused | :confused:

Read up on ADO in MSDN. That is one way of doing what you need. I am assuming the appropriate drivers are available. I have never used Sybase myself but see no reason why ADO and ODBC will not let you connect. There are sevral examples in MSDN.

Try:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ado270/htm/dasdkadooverview.asp?frame=true

There are also many articles on CodeProject discussing ADO.

Use a command object, or wite the SQL yourself e.g.

strSQL = { CALL myStoredProcedure ('txtParam', 'numParam', #01-Jan-2002#) }

If the SP returns a recordset then

dim rs as new adodb.recordset

rs.open strsql, cnn, ...., ....

I have connected to Sybase from VB using DTS on MS SQL Server; the only problems i really had was datatypes. Money doesn't equal money, etc.

Here is a bit of my code. It's much like connecting to any other ADO or ODBC device.

<br />
Set oConn = CreateObject("ADODB.Connection")<br />
oConn.Open "Srvr=[servername];Driver={SYBASE SYSTEM 11};uid=[username];pwd=[password];"<br />

And yes you have to have the proper drivers installed on your machine to connect to sybase.

Real programmers don't document. If it was hard to write, it should be hard to understand.

Windows Components Checker

How can I programmatically check if a certain Windows component (e.g., Dial-Up Networking) is installed?

Is there a way for a VB program to launch the installation process for a missing component?

Platform differences?

Anyone?

I'm not an expert but wouldn't you just create a component via its ProgId which you can lookup with the OLE/COM viewer in VC++? It's also known as the OleView tool on Start Menu | Programs | Microsoft Visual Studio 6.0 Program | Microsoft Visual Studio 6.0 Tools submenu.

e.g. Set objScripObj = CreateObject("MSScriptControl.ScriptControl.1")

Just trap the error (On Error....) if the Set statement fails, then it is not installed on the system or in the registry. As far as installing a missing component, you would have to provide it since it isn't already installed and if its the DUN object, I don't know about the compatability between different Windows OS.

Adding a form to and existing form

16-Jul-02 10:11

I have no idea what to do. i would like to add a form to an existing form by way of button.(i push a button, it should load form2 with my controls on it.) i tried the
application.run(windowsapplication1.form2) under Button1_click sub, and it doesn't work. (it says something about threading error.)

<marquee>
Help me!!

-or-

Dim F2 as new form2
F2.ShowDialog()

Hope this helps.

sub button1_click()
form2.show
end sub

custom treeview

I've created a my own node class that inherits from treenode and included some extra properties. When I try and add one to a normal treeview, my custom properties are gone. Here is what I do:

Dim temp as new myNode()
with temp
'set some properties
End with
treeview1.nodes.add(temp) 'I'm assuming that here it gets converted to a normal node.

To get around this, I tried to make a custom TreeNodeCollection, but the IDE gives me problems with sub new. To see the errors, copy this:

Public Class myCol
Inherits TreeNodeCollection
'...
End Class

I would greatly appriciate any help.

Hi,

When your going to retrieve the TreeNode you'll have to cast it to the right object-type like

- Custom node-class = TreeNodeEx

Private Sub TreeNode1_Click(sender as object, e as TreenodeEventArgs) ...<br />
    Dim MyTreeNodeEx As TreeNodeEx<br />
<br />
    MyTreeNodeEx = CType(e.Nodes.SelectedNode, TreeNodeX)<br />
    ...<br />
End Sub

This is what I'm doing when using the treeview with custom nodes.

I hope this answers your question.

Greets,

Poolbeer

i use a text box for my applicationa nd am right nowhaving 2 problems that i need to address.

1). Whenever that text box gains focus for user to input data the cursor goes and stands right in the middle of the first line,While i want it to stand at the extreme left ahnd top corner.Now what property of the textbox do i need to meddle with to get what i want.i tried so many things but nothing seems to work.

2). when i use the ' symbol in my data input inside the text box like say "I've a good car" im not able to input data inside the databse becos of the "'" symbols importance in a database.now how do i overcome it.do i ahve to search for every text in my text box for that occurence and change it to something else??

Try this in the Focus event: TextBox1.SelectionStart = 0 and TextBox1.SelectionLength = 0
(In VB6, these are called SelStart and SelLength)
sValue = TextBox1.Text.Replace("'","''"),
or in VB6, sValue = Replace(TextBox1.Text, "'", "''")
