I imagine that all the system knows for sure is that there's no CD there. I am pretty sure there's an API to open the door, if there's no CD, you could open it, and then know it was open :P

Yeah u r right, through the API I'm using for MCISendstring function, the system can identify whether a cd is present in the drive or not through the command- mcisendstring(Status CDAudio Mediapresent). It returns true or false accordingly. But to be precise, the problem lies during the absence of any cd. At that time the command- mcisendstring(Status CDAudio Mode) is returning the same value- OPEN regardless the open or close state of the tray door. Can U plz focus more on it? Thanx.

hi all,
im using winsock array in vb6, i converted to vb.net 2005 platform...they created a axwinsockarray .dll.. my question is : it is useful using winsock in vb.net 2005 ?
until now the conversion is good .. but i don't know if it will be an error in futur by using winsock inside vb.net 2005 ....
can anyone help me thanks in advance.

I believe winsock went the way of the dinosaurs in .Net. It was replaced by System.Net.Sockets Namespace[^], and on a high-level by TcpClient [^] and TcpListener[^].
So, I suggest migrating to one of those to make it easier and avoid any unnecessary problems.

If you are using the winsock (VB.NET 2005) for desktop application then no issue. You will get the same functionality with InterOp Winsock component i.e. AxWinsockArray.dll.
Otherwise instead of InterOp Winsock you can use the socket programming, which is a great alternative of winsock.

I am trying to get a variable to pass to another procedure.
I have set my procedure as follows
Sub Procedure(X)
' programming code
End Sub
Normally I would use the following to send data
Procedure1 Count6
however in this case I am running the called procedure using this code
With ActiveWorkbook.Sheets(SetMonth).Buttons.Add(600, 20, 100, 25)
.OnAction = "Procedure1"
.Caption = "Bills Not Paid July"
.Name = "JULY"
End With
how do I adapt the ".OnAction = "Procedure1" section to pass the variable"
Can anyone help me

Hi
The issue with specifying the parameter when you create the button is that the value for the parameter will be fixed.
For instance:
Public Sub CreateButton()
With ActiveWorkbook.Sheets("sheet1").Buttons.Add(600, 20, 100, 25)
.OnAction = "'Procedure1 ""Hello"", " & nCount & "'"
.Caption = "Bills Not Paid July"
.Name = "JULY"
End With
End Sub
Public Sub Procedure1(ByVal s As String, ByVal x As Integer)
MsgBox s & " " & x
End Sub
In the code above, even though the parameter is specified as a variable, the value when you _define_ the OnAction is what will be passed in.
To get around this, you could try this:
Public Sub CreateButton()
With ActiveWorkbook.Sheets("sheet1").Buttons.Add(600, 20, 100, 25)
.OnAction = "July_Click"
.Caption = "Bills Not Paid July"
.Name = "JULY"
End With
End Sub
Public Sub July_Click()
Call ActiveWorkbook.Application.Run("Procedure1", "test", nCount)
End Sub
Public Sub Procedure1(ByVal s As String, ByVal x As Integer)
MsgBox s & " " & x
End Sub

What I need to learn?
Thanks in advance.

Visual Basic 6 is a different language from any version of VB.Net. However, the transition should not be hard at all. Just Google for differences between VB6 and VB.Net and you'll find lots of sites, such as this[^] one.

Quit, oh sorry I thought you were STARTING a new project in VB6. The company really needs to look into a rewrite of the application. Support resources for a language that has not been supported for 6+ years are obviously getting thin on the ground, also training resources will be fast dissapearing other than the net.
Never underestimate the power of human stupidity

Am sorry to hear that your Company still wants you to Support vb6, but realy its true(They have to rewrite the Application to .NET), vb.net and Vb6 are different Animals. But it shouldnt be a hard thing, when you get stuck you can just Google.

Hi,
How to set Control Panel's Language settings (Regional and Language Options)from VB Application. When I change the Language Option to Swedish Language, I want to Show those date Formats in all the Forms of the Application.
I am using the VB 6.0.
Through Shell command i am able to access the code but not able to proceed ahead.
Help in this regard is highly appreciated.
Regards

Hi,
most control panel stuff should be only be manipulated interactively by the user, and not be
modified by a program. What would happen if different programs started to set different values
for the same system properties?
I really don't know how to change system settings programmatically either.
I do know how to tell an app to use specific settings tho:
- you can specify date, time, currency formats explicitly every time you need them (say in ToString)
using one of the method overloads
- you can specify an overall Culture for a thread (see Thread.CurrentCulture)
- AFAIK you can't specify it for the entire app (Application.CurrentCulture works on a thread too).
Hope this helps.

Dear Gurus,
I am trying to write an application to manipulate Publisher 2003 usign VB 2008.
Please find below my calling code in the module,
Module Module1
Declare Function GetCusorPos Lib "user32" Alias "GetCursorPos" (ByVal lppoint As Pnt) As Boolean
End Module
and here the declaration of structure Pnt,
Public Structure Pnt
Dim Ptx As Integer
Dim Pty As Integer
End Structure
The actual lines of calling code
' Stoploop declared as boolean at beginning
Dim Po As Pnt
Po = New Pnt
StopLoop = True
While StopLoop
GetCusorPos(Po)
tbMouseX.Text = Po.Ptx
tbMouseY.Text = Po.Pty
System.Windows.Forms.Application.DoEvents()
End While
actually there are two textboxes which will receive the input.
The error is
Initially, cannot find an entry point in DLL
Later, the values of Ptx and Pty are zero.
Please guide me what i have done wrong and for the past two days i am searching on and on... Thanks in advance.

Hi,
there are several problems here:
- the method you want is called GetCursorPos, not GetCusorPos;
that is good enough a reason why it can't be found
- GetCursorPos needs a single argument: the pointer to a structure of type POINT
so:
1) your declare statement is wrong; it needs the ByRef keyword
2) your GetCursorPos invocation is wrong; you passed a value (i.e. a copy of the current content of your struct).
Hope this helps.

Dear Luc Pattyn
Many thanks, the problem is solved.
I initially put getcursorpos, but later i inadvertently made a typo.
The real thing is using Byref instead of Byval.
Also can you kindly answer one more thing, is there any other way to access APIs without messing up with names and byref, byval etc., please guide me.

You'll need to be more descriptive. Every memory card I've ever wanted to read has been accessible through a drive letter.
