Right... the Dim statement is limited to declaring variables within Functions or Subs, any other declarations in your classes or modules must be marked Public, Private or Protected. Does that help?

How do I get the real serial number of the hard drive and mother board in VB6
|
|
|
|
|
The GetVolumeInformation API will return a hard drive serial number.
Don't know about motherboard.

You'll have to use WMI (Windows Management Instrumentation) to get this information. Be warned though, not all manufacturers supply providers that will server up this information.

I have an Access form that I created an Unbound OLE object frame on it. The OLE object was configured (by the Wizard) to accept Excel and I want to use it as a portal to import Excel worksheets into my Access DB (drag/drop filename and voila, my OLE object has an Excel sheet!)
My question is, once that the Excel worksheet is in the OLE object, how can use VBA code to go through the Excel object and extract field values and populate a given Access table?
Here are some defintions that I started to try but did not work:
<br />
Private Function ReadExcelObject()<br />
Dim bRetStatus As Boolean<br />
<br />
Dim oXLapp As Excel.Application<br />
Dim oXLwsh As Excel.Worksheet<br />
Dim oXLrng As Excel.Range<br />
bRetStatus = True<br />
<br />
'OLEUnboundExcel is an Unbounded Object Frame<br />
' Set oXLapp = OLEUnboundExcel.Application 'this produces a type-mismatch<br />
' Set oXLwsh = oXLapp.Worksheets(1)<br />
'OLEUnboundExcel<br />
'Set oXLapp = GetObject(, OLEUnboundExcel)<br />
' Set oXLapp = OLEUnboundExcel.Object<br />
' Set oXLwsh = oXLapp.Worksheets(1)<br />
<br />
'what do I do to make this work???<br />
<br />
ReadExcelObject = bRetStatus<br />
<br />
End Function
Thanks in advance!

I'm trying to retrieve a value in the registry that is a Qword (64bit value). Anybody have any idea how I can accomplish this with .NET v 1.0/1.1? I've tried retrieveing it as binary and as a string with no prevail. I have also tried using RegOpenKey/RegQueryValue API with no luck (even retrieving normal registry values).
So basically anyone know how to accomplist this natively in .NET? I have tried several different declarations for the API and no luck, am I doing something wrong (.NET permissions possibly)?
I have a .reg file to add a qword to the registry if needed.
Thanks,
-Jerry

Can't be done with the .NET BCL. You have to use the Win32 API functions to read/write a REG_QWORD value. I don't have any example code to show you because, frankly, hardly anyone ever uses the obscure little value type. I'll see if I can whip something up when I get home.

Thanks a lot Dave!
Yeah I got it to work with the API's. However I declared the data as a String in RegQueryValueEx and man did it take some jumping through hoops in order to convert it to a long. I tried the declaration with a long (int64) but I forgot the value is unsigned. Doh! Needless to say your code is a bit more efficient. 
For some reason the declaration I had wasn't working. After letting it sit for a bit and going back to it (and a reboot) the code worked fine. Since I'm relatively new to .NET, I thought it might be some type of framework security feature. It was really weird cause the return value was always a really high non zero for the RegQueryValueEx, which really stumped me.
Guess it was just one of those days of banging your head against the wall...
(plus i never got an e-mail that you responded.. oh well)
Thanks again,
-Jerry

For testing I have added in form1
Public WithEvents myEvent As New Array1(New Panel) and added something to do when event is triggerd
Public Sub myEvent_Clicked(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles myEvent.Clicked<br />
MessageBox.Show("Button pressed")<br />
End Sub
To test the event I have added a button who's fireing the event in Array1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
myEvent.OnOff_ClickHandler(sender, e)<br />
End Sub
In Array1 there is the routine
Public Sub OnOff_ClickHandler(ByVal sender As Object, ByVal e As System.EventArgs)<br />
MessageBox.Show("Event routine")<br />
RaiseEvent Clicked(sender, e)<br />
End Sub
When I click button1 the event RaiseEvent Clicked(sender, e) is fired but when I click a button from the array panel with AddHandler aButton.Click, AddressOf OnOff_ClickHandler then nothing happed. I see the first message with "Event routine" appear but the second not
What's the different between a fixed button and a button from an array control?
In my opinion nothing but who am I

hy everyone
I do want to realice a kind of permutation in a VBA programm
Lets say I do have the three integer pairs "100 - 120", "200 - 220" and "300 - 320".
Now I would like to let my programm select every possible permution of them, meaning the lowerone of the first, the lower one of the second and the lowerone of the third.
Let me describe with a set of two pairs.
Lets say I do have the pairs "1 - 2" and "3 - 4" so my proggy should allow to access every permution, either for output or for furter use.
Well I will have to get "1 3" "1 4" "2 3" and "2 4".
This should work for every amount of pairs available. Lets say 16 or 20 pairs with a lower and higher number.
I thought about an inner and outer loop but this way I was not able to get all the permutations.
Does anyone of you know how to realice that.
Thanks!
Stephan.

Well I realized I do not need every permutation, I do only need any combination of the min max values
lets have alook at the followin example
lets say I do have the intervals "A - B", "C - D" and "E - F"
now I do want to get any min max combination (because I do want to use this for an addfunction there is no different if lets say A is in first, second or third place. Meaning e.g. ACE = CEA = EAC etc.
Therefor I do only need ACE, ACF, ADE, ADF, BCE, BCF, BDE and BDF.
Every other combination is not needed because plus is commutativ (see above)
If you do have a look at this with it's index then you might realice there is every bitcombination in it. Because lets say the minimum is 0 and the maximum is 1 in indexing then you do get 000 up to 111.
And that's what I do want to realize for "length" 2 to 10 (or even higher).
Well I could use 2, 3 ... loops in loops but well in the beginning I do not know how many are needed. Well maybe I should try to think about a bitmap using an array doing something like
if most right position in array is 0 then set it to 1, if it is already 1 then set it to 0 and increase the next position. if this is already 1 then increase the next and set this to 0 etc. 
meaning 000 +1 => 001 001 + 1=> 010 .... 011 +1 => 100 ...
Does anyone of you know a better solution for this? If so please let me know!
Because in my example I have to check the bitarray and this task gets bigger for every combination, which is not a good idea concerning performance. 
Thanks!
Stephan.

in my client server project when I call Frm.show the form stops responding, the code is very basic, some data is sent from the server witch tells the client what form to load then In a sub I call
form1.hide
form2.show
|
|
|
|
|
Hi There
You have to create instance of the form and then call the methods. If the form is Form1 it should be some what like this
F1 as Form1
F1.Show
F1.Hide

Hy everyone!
I want to do some stringparsing, but well I seem to having done to much programming in C# and C/C++. So I guess I start mixing things.
So what I want to do is the following:
I do have an input in an Excel Cell which looks like "xxx-yyyy" or maybe even blanks between them like "xxx - yyy" etc. xxx and yyy represent integers. So now I do want to split this string to get xxx and yyy in seperate integer variables. Well I guess it is quit simple, but at the moment I seem to be mixing things. I know how to do this in C# etc (parsing the array of char) but well...
the info I collected from the sheet is stored in a variant variable, because the user should be allowed to either enter "xxx" or "xxx-yyy".
Thanks for your help.
Stephan.

I just found out myself. I have to use the Split(string) operation but is there any way to split the string without having blanks to seperate it?
If anyone of you knows how to split "123-234" into 123 and 234 (meaning the two integers) then please let me know. At the moment I am able to split "123 - 234" into "123" "-" and "234" but well, if there are no blanks inbetween my programm will crash. And I really would like to avoid this
Thanks.
Stephan.

Why use split? Just use SubString:
Dim a As Integer
Dim b As Integer
Dim s As String = "123 - 456"
Dim i As Integer = s.IndexOf("-")
If i < 0 Then
'must be in xxx form
a = Integer.Parse(s)
Else
'in xxx-yyyy form, so parse
a = Integer.Parse(s.Substring(0, i))
b = Integer.Parse(s.Substring(i + 1, s.Length - i - 1))
End If
This will work if spaces or no spaces. If you need the strings rather than the integers, just use stringa = s.Substring(0, i).Trim. The trim will remove leading or trailing spaces.

Well, seams as if VBA for Excel does not support "Integer.Parse"
Or does it? At the moment I am on Office 2000 but might soon be updating to Office 2003.
I had a look and the help says there is only a normal parse operation. The examples says parsing a telephonenumber and seperating it into two Cells (similar to my example). Maybe I could use this one ...
Or was your example supposed for .NET? Because actually I do not have this installed here and at the moment I do not have access to it. So I have to get along with what Office is offering 'til I will be able to use .NET

Sorry,
In Excel, it would be something like:
value = "123 - 456"
Pos = Instr(value,"-")
If Pos > 0 Then 'I think position starts at 1 in Excel
a = Val(Left(value, pos - 1))
b = Val(Right(value, Len(value) - Pos))
Else
a = val(value)
End If
I can't check at this computer because I don't have anything with old vb on it here.

now that i ponder on it a bit, when i use the split function in c# i simply do the following -
myString.split('-')[0] //gets xxx
myString.split('-')[1] //gets yyy
I wonder if you couldn't do the same for vb.net i.e.
myString.split('-')(0) //gets xxx
myString.split('-')(1) //gets yyy
|
|
|
|

You can but VB.net likes you to specify that the splitter character is of type char. Also the single quote is the comment character in VB.Net so you have to use double quotes.
myString.split("-"c)(0) 'gets xxx
myString.split("-"c)(1) 'gets yyy
If you have knowledge, let others light their candles at it.
