My first thought was:
In your timer event -> timer1.enabled = false
this deactivates your timer
Now I tried what Aslam told you, and it works.
I cannot remember: What did I before google?

Vb is hanging?
Try this code:
For index = 0 To nCount
If (g_TimeOut = True) Then
Debug.Print "Got the signal from the timer so ending the counter"
flag = True
Exit For
Else
Debug.Print "Still Counting...." & index
DoEvents
Sleep 1000
End If
Next index
If nCount<5 then the timer is useless.
If (flag = True) Then
Debug.Print "Did not got the signal, still ending the counter."
End If
Here the condition: flag = True False. True means Got the signal.

If you're new to VB, abandon VB6 now before you learn too many bad habits. VB6 is dead and hasn't been supported by Microsoft for quite a long time.
Pickup VB.NET instead, or C#, and learn that. You can get the Express (Free) editions of VB.NET or C# here[^].

Thanks Aslam,Thomas,Dave
did not see that flag = True mistake(did a silly mistake), ya corrected it. Also after putting DoEvents its working now. But its entering the timer1 function 2 times. I am getting the output like this
Still Counting....0
Still Counting....1
Still Counting....2
Still Counting....3
Still Counting....4
Still Counting....5
Inside the Timer
Got the signal from the timer so ending the counter
Got the signal from the timer so ending the counter
Inside the Timer
@Dave - I need to do some enhancements to an already existing VB6 project. For that only I am trying this.

Why not converting your entire project into VB.NET?
You can do that by creating subsystems.
One by one convert them if you can’t convert entire system at once.
A lot of tools around the world to convert from 1 language to other.
Try this one:
vbconversions[^]
I found it useful.

This idea would be ok ... but there are two reasons why we didn´t:
1) The rest of the company only uses C#. So the .NET parts I have to write are in C# (which I like very much). If I only talk about VB.NET they scream "heresy".
2) Beside that, the code base I´m working on is quite large, and .... ugly (= evolved over more than 12 years, there were a lot of changes). Converting this to VB.NET would only result in having a big bunch of ugly .NET code. Not really better!

Here's a "technical" reason: Windows 8 won't support the VB6 runtime.
|
|
|
|
|
That would be nice: Than we will gain a lot of money to convert it 
Can we be shure (Win8->noVB)?

Yes, Microsoft has come out and said they will not support the VB6 runtime beyond Windows 7.

DoEvents is the devil. It may cause event handlers (that contain DoEvents calls) do become re-entered. If you think you need DoEvents, what you probably need is another thread.
And no I don't have VB examples.

Hi all,
I managed to add a RSS subscription to Outlook 2010 by code:
Private Sub addRSS_subscription()
Dim myApplication As New Outlook.Application
Dim feedUrl As String = "outlookfeed://www.nu.nl/feeds/rss/algemeen.rss%23"
Dim myMAPInameSpace As Outlook.NameSpace = myApplication.GetNamespace("MAPI")
Dim ImportRSS As Outlook.Folder
ImportRSS = myMAPInameSpace.OpenSharedFolder(feedUrl, "Nu.nl RSS", True, True)
End Sub
The thing I don't know how to handle, is to change the delivery location of added RSS subscription from RSS folder to my inbox.
Anyone know how to do this.
Kind regards.

I managed it by adding a rule to Outlook on the RSS folder by code.
Thanks!

Here is the problem :
- The application is in VB6.
- A dll provide services of computing.
- In the dll function, VB6 application provides a callback used by dll for progress of computing.
- For exemple, here is the prototype of dll function :
Public Declare Function NeuroComputerLearning Lib "NeuroComputer.dll" ( _
ByVal parameters As String, ByVal stepFunction As Long) As Integer
- Here is the VB6 function that dll has to call :
Function stepLearningFunction(ByVal step As Long, ByVal percent As Long) As Long
FrmMAIN.refreshLearning step, percent
stepLearningFunction = 0
End Function
- Here is the prototype in dll :
__declspec(dllexport) EnumError NeuroComputerTest(
LPSTR parameters,
void (*stepFunction) (LPSTR step));
- The call in VB6 is :
report% = NeuroComputerLearning(parameterFileName$, FnPtrToLong(AddressOf stepLearningFunction))
The dll success to call the "stepLearningFunction" that correctly do his job, but crash at the "return" of the call.
The popup message is :
"Run-time Checl Failure #0 - The value of ESP was not properly saved cross a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention."
How to solve this ?
Best regards.

Sorry, but I have already the answer.
This is done by a cast in the dll prototype.
We don't declare the call back with its own parameters, but as a long.
We do the cast after.
So :
EnumError NeuroComputerLearning(
LPSTR parameters,
long cbAddress ) {
typedef long (__stdcall *funCB)(long step, long percent, long requestAbort);
funCB stepFunction;
stepFunction = (funCB)cbAddress;
// and then we call the call back
if (stepFunction != NULL) stepFunction( theStep, thePercent);
And it runs perfectly.
I can too add a "abort" parameter that VB6 can fills during process if abort is required.

Dear all,
Here I attach my Visual Basic Code for Combo Box Control runs in Microsoft Excel Macro, but once the object is run and I click this object control the item will increase continuaously.
Wheather any of you who can asisst me solve this problem..?
Private Sub ComboBox1_Change()
ComboBox1.AddItem "SIDM"
ComboBox1.AddItem "BIJ"
ComboBox1.AddItem "M1D"
ComboBox1.AddItem "THERESA"
ComboBox1.AddItem "YS"
ComboBox1.AddItem "OPTION"
End Sub
Best Regards,
Ahmad Rifai Yusuf

I think you really need to think this one through. ComboBox Change event fires everytime there is a change to the contents of the ComboBox, and yet you are adding more items to the ComboBox every time it fires. This will set up a continuous loop, that will run forever. You need to fill the ComboBox only once, and then use the Change event to execute instructions against the selected item.
|
|
|
|
|
You either need to make this a once only event, a simple flag and IF THEN would do it, or reset the combo box each time.
Depending on what you need either is a valid option.
<br />
ComboBox1.Items.Clear() would do the trick.
Otherwise as I say just call the population once at the beginning.

Visual Basic Question?
'Please Modify this program to lock drive C: and D:
Private Sub Command1_Click()
Dim fs As New FileSystemObject
Dim f
Dim strPath As String
strPath = "C:\TestFolder"
Name strPath As strPath & "A"
Set f = fs.GetFolder(strPath & "A")
f.Attributes = -1
End Sub
Private Sub Command2_Click()
Dim fs As New FileSystemObject
Dim f
Dim strPath As String
strPath = "C:\TestFolder"
Set f = fs.GetFolder(strPath & "A")
f.Attributes = 0
Name strPath & "A" As strPath
End Sub
' It has two buttons in a form; lock folder and unlock folder
Please help

There is no code in here that will "lock" a folder on any drive. No one is going to write your code for you.
In order to help any further, you're going to have to define what you mean by "locking a folder".
|
|
|
|
|
Despite that you didn´t define what "lock" means - as Dave already mentioned - the 2nd question: Convert into what?
I cannot remember: What did I before google?

You have to use port 587. Reading the documentation on the SmtpClient class states that:
An alternate connection method is where an SSL session is established up front before any protocol commands are sent. This connection method is sometimes called SMTP/SSL, SMTP over SSL, or SMTPS and by default uses port 465. This alternate connection method using SSL is not currently supported.i>

- I completely agree with your opinion concerning VB6. Unfortunately the VB6 App I´m working on is quite suitable, and the customer is uneager to pay a lot of money only for "technical" reasons.
