First Sorry For My Bad English ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
In easy way  (for me  ) to assign object variable to become object is using Set statement. Example:
...
Dim oForm As Form1
Set oForm = New Form1
... But In other case I found a hard way  (for me again of course ), how can I get object and assign it to variable, in condition that I just only have the Object.hWnd value??
Plez can some one in the light place  or in the dark place  can help me to get object, if I just only have the Object.hWnd value???
One more things if any one can help me, please send the answer to my Email.
Best regards,

Nope. That's not how this works...
Ask for your question....Your English is pretty terrible, so let me see if I got this right. You trying to create an instance of an object, using nothing but a handle??
Well, the Control class will return a Control object using its shared FromHandle method.
Dim objControl As Control = Control.FromHandle(handle)

Are you saying that you're looking to create an object from ANY window handle, even if your app didn't create the window?
It doesn't work that way. You can't create an object for a window that the .NET Framework didn't create.
And I made th comment I did because your question is impossible to understand with any certainty. It's also why I'm asking more questions about your questions. We need clarification!

What I mean with "The code isn't work in VB not .NET" is the code that you wrote isn't work in VB6 and the code that I wont is in VB6 not in VB .NET, sorry if it become a little mis-Understanding. Why I want to try it in VB6 so deeply, because in MSDN I saw the code like you wrote, but the defferent is that code in MSDN is wrote in VC6. If I not wrong the code is something like this:
...
oThing = FromHandle(hWnd)
... So I wondering if any way to do that in VB6?

No, there isn't. VB6 cannot create Form wrapper objects around windows that were not created under the VB6 Runtime.

Can anyone help with this. . . I am creating an application using an MDI form. The child form displays fine when I select the menu option. However, I do have two issues.
1) If I select the menu option a second time - a second form is displayed. I want to limit this to only one instance of this particular form.
2) If I close the form and click on the menu option, the next instance of the form does not appear in the same spot. It appears slightly below where the previous form appeared.
Here is a snipet of the code. . .
Private Sub mnuAdminTradeManager_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuAdminTradeManager.Click
'Declare new Trade Manager form
Dim frmTradeManager = New frmTradeManager
'Set the child forms MdiParent property
frmTradeManager.MdiParent = Me
'Show Trade Manger
frmTradeManager.Show()
End Sub
Thank you

Try this (it can be used for all the child form)..
Private Sub mnuAdminTradeManager_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuAdminTradeManager.Click<br />
<br />
Dim frmTradeManager As frmTradeManager<br />
<br />
frmTradeManager = IsOpen("YourFormName")<br />
If frmTradeManager Is Nothing Then<br />
frmTradeManager = New frmTradeManager()<br />
ShowForm(frmTradeManager)<br />
Else<br />
ShowForm(frmTradeManager, True)<br />
End If<br />
<br />
End Sub<br />
<br />
Private Function IsOpen(ByVal formName As String) As Object<br />
Dim intChildCount As Integer<br />
For intChildCount = 0 To Me.MdiChildren.Length - 1<br />
If Me.MdiChildren(intChildCount).Name = formName Or Me.MdiChildren(intChildCount).Text = formName Then<br />
Return Me.MdiChildren(intChildCount)<br />
End If<br />
Next<br />
Return Nothing<br />
End Function<br />
<br />
Private Sub ShowForm(ByRef DisplayForm As Form, Optional ByVal isOpened As Boolean = False)<br />
Try<br />
DisplayForm.MdiParent = Me<br />
DisplayForm.WindowState = FormWindowState.Maximized<br />
If isOpened = False Then<br />
DisplayForm.Show()<br />
Else<br />
ActivateMdiChild(DisplayForm)<br />
End If<br />
<br />
Catch exc As Exception<br />
Throw exc<br />
Finally<br />
End Try<br />
<br />
End Sub
I hope this will help u......

Hi ,
Is it possible to use Indexed text box, bcz I want to do some manipulations like when enter some numbers into text box (Some grid like) I want to calculate the average and upper n lower limits like that..
Thnx
Jr

There's no such thing as an Indexed TextBox, or what used to be, in VB6, a control Array. You can simluate such things yourself. All you need to do is add all the TextBoxes to your own array.
Dim textboxes(10,10) As TextBox
For i As Integer = 0 to 9
For j As Integer = 0 to 9
textboxes(i,j) = New TextBox()
With textboxes(i,j)
.Location = New Size(blah, blah)
' keep setting properties for your TextBoxes...
End With
' Don't forget to add each TextBox to the Form's
' Controls collection, otherwise you'll never see it!
Me.Controls.Add(textboxes(i,j))
Next
Next

Hi kamalika,
Before calling dao.Update to insert/update or delete data from Dataset to database you have to set the dao.InsetCommand,dao.UpdateCommand and dao.DeleteCommand property with approriate command

Hello All,
I'm at work trying to write a Test Case script to run in VB6. The test case needs to test many many different combinations of parameters. For example, let's say I have 12 parameters, and I need to test the available types of data types that the parameters can take. Let's say that each parameter has 4 data types. I need to test every possible combination of every data type and parameter. If I were to do ALL of them, I would end up running over 20,000 test cases!!! However, with Pairwise testing, which only picks out the best possible combinations needed, the number of test cases dramatically reduces to about 25 or so. This software is available out on the net to get this result (www.satisfice.com), however, it must be run in DOS mode or through the command line. This makes my automation a problem, where a manual step must be taken to retrieve these combinations.
The idea looks like this...
Param1 Param2 Param3 Param4 ...
1 1 1 1
2 2 2 2
3 3 3 3
My question is...
Is there anyone out there that knows of, or knows where to find, an algorithm that can calculate the PairWise pairings? It could be in VB6 or VB.NET, I'll know how to convert the two.
Any insight or ideas would greatly help me.
Thank you for your time.

Hello again, just another question.
I've created a solution which contains an executable and a DLL. I want this DLL to be registered during installation. I create an installation project and drop the executable, which in turn carries along the DLL. To test the installation process, I create another folder in Common Files to hold the DLL, and I mark the DLL with the Register option to COM and COMRelativePath (I have tested both). But when I test the installation on a machine other than my development one, the DLL seems not to be registered. In fact, if I use gacutil on that machine after installation, everything works as expected.
What have I been missing?
Thanks in advance and best regards,
Juan Pedro Pérez

I have never in my life coded any Visual basic before the last few days, I am more of a C kinda guy, so I wonder if somebody could help me a little with some of my functions.
I am creating an ActiveX dll which is to be used with a C project of mine. The purpose of this dll is to perform all my Excel needs. I am having trouble getting the following to work:
Public Function CloseFile(FileName As String, Save As Boolean)
xlApp.Workbooks(FileName).Close savechanges:=Save
End Function
Whenever I call it I am confronted with a message box displaying "Subscript out of range".
Also with the following:
Public Function GetCellString(RowId As Integer, ColId As Integer) As String
GetCellString = xlSheet.Cells(RowId, ColId).Value
End Function
Most of the cells containing floating point numbers, but for simplicity I am returning a string. Problem is, I am only getting the whole number (before the decimal point) instead of a float.
Any help would be greatly appreciated.
