Hey ppl, I have ported this code from a vb6 example, but can't seem to get it working... Any ideas Confused | :confused:

<br />
  Private Class TitleBarInfo<br />
            <System.Runtime.InteropServices.DllImport("user32")> Shared Function GetTitleBarInfo(ByVal hwnd As IntPtr, ByRef pti As TITLEBARINFO) As Boolean<br />
            End Function<br />
<br />
<br />
            Private Const STATE_SYSTEM_FOCUSABLE As Integer = &H100000<br />
            Private Const STATE_SYSTEM_INVISIBLE As Short = &H8000S<br />
            Private Const STATE_SYSTEM_OFFSCREEN As Integer = &H10000<br />
            Private Const STATE_SYSTEM_UNAVAILABLE As Short = &H1S<br />
            Private Const STATE_SYSTEM_PRESSED As Short = &H8S<br />
            Private Const CCHILDREN_TITLEBAR As Short = 5<br />
            Public Structure RECT<br />
                Public left As Integer<br />
                Public top As Integer<br />
                Public right As Integer<br />
                Public bottom As Integer<br />
            End Structure<br />
            Public Structure TITLEBARINFO<br />
                Public cbSize As Integer<br />
                Public rcTitleBar As RECT<br />
                <VBFixedArray(CCHILDREN_TITLEBAR)> Public rgstate() As Integer<br />
                Public Sub Initialize()<br />
                    ReDim rgstate(CCHILDREN_TITLEBAR)<br />
                End Sub<br />
            End Structure<br />
            Public Shared Function GetTitleBarInfo(ByVal Handle As IntPtr) As TITLEBARINFO<br />
                Dim TitleInfo As TITLEBARINFO<br />
                'Initialize structure<br />
                TitleInfo.Initialize()<br />
                TitleInfo.cbSize = Len(TitleInfo)<br />
<br />
                GetTitleBarInfo(Handle, TitleInfo)<br />
return TitleInfo<br />
                Return TitleInfo<br />
            End Function<br />
        End Class<br />

Private Structure TITLEBARINFO
Dim cbSize As Integer
Dim rcTitleBar As RECT
<VBFixedArray(CCHILDREN_TITLEBAR + 1)> _
Dim rgstate() As Integer
Public Sub Initialize()
ReDim rgstate(CCHILDREN_TITLEBAR + 1)
End Sub
End Structure

and

GetTitleBarInfo(Me.Handle.ToInt32, TitleInfo)

hope this helps

Sorry AndrewVos,
I sent that last message to fast, I checked it again and I was still getting a error 87, sorry.

add this import:
Imports System.Runtime.InteropServices

and the structure should be more like this:

<StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Ansi)> _
Private Structure TITLEBARINFO
Dim cbSize As Long
Dim rcTitleBar As RECT
<MarshalAs(UnmanagedType.ByValArray, SizeConst:=CCHILDREN_TITLEBAR)> _
Dim rgstate() As Long
Public Sub Initialize()
ReDim rgstate(CCHILDREN_TITLEBAR)
End Sub
End Structure

It should return err code 0 now.

hope that helps

Still not working... The elements of rgstate() are all = 0.

MSDN on the GetTitleBarInfo function.....

"If the function succeeds, the return value is nonzero."

Yeah, I been tweaking the code for a while now with no luck, anyone with a good understanding of interop, please comment, thanks.

AndrewVos,

Sorry, I was woring on it between other code so it didn't get my full attention or time, I think this solution should work now that I've had time to see what was going on. It works on my end.

End With
'return with the TitleInfo
Return TitleInfo

Shweeet. Dunno how u got this working properly, well I havent reviewed it yet properly, but everything seems right.
Thanks alot Anonymous!

I actually resorted to GetWindowLong to check if the caption buttons r there.

Well done, ur a genius :>

Registry Entry (SaveSettings)

AndrewVos,

Thanks, it was interesting, and no problem, I don't log in a lot of times either.

i have an application that I wrote about a year ago. Within this application I allow certain users to change the DB access for all users of the application on a given PC.

SaveSetting("DMaTS", "SQL_Server", "ServerName", gstrServer)
**where gstrServer is the name of the server)

This has worked without issue until recently when I have opened this code up and have added new functionality. Now the SaveSettings only works for the user that applied the DB Change. Is this change if bahavior something to do with some security patching?

If I do a registry check for the entry is lists under "Current User..."?

I am a bit puzzled by this change in behavior and am looking for an explanation of why, as well as any corrective action I should take to correct my code and coding habits.

Thanks in Advance.

mtognetti.

SaveSetting has always saved to HKEY_CURRENT_USER. I don't know what's changed, but this functionality wasn't it. Anything saved under CurrentUser is visible only to the user that saved it, not to anyone else.

If you need to save application settings that apply to all users of your application, then they should have gone under HKEY_LOCAL_MACHINE.

Set folder permissions -- PLEASE HELP!

6-Jul-05 8:24

As I have done some further reading since posting this I have come to the same conclusion that you have.

Thank you for the validation. I will now redefine this to actually change/add the setting to HK_Local_Machine. This way I will actually get the functionality that I am expecting...all of the time.

Thanks again.

Hi everyone,

I have found tons and tons of code on how to add users to the active directory, but I have not found much on how to set folder permission for these users. I have an FTP site that I use a batch to create 50 username and password combinations and then I add those to the active directory (currently by hand; working on code for autonomous). I then have to set all the user permissions to the folder that is reserved for each user. Everywhere I look there is very little discussion on how to do this automatically. Any help is VERY appreciated. Thanks!

Is the IF statement the best choice for this?

Here is a sample code I would like to be able to cut in half. The Dim is the only difference. I want to connect to a different db - through web services - based on a command button clicked in Excel. I currently have the button set a property (thanks Dave) in the form but this is a bunch of repeated code (and this is one of the short segments). I would put just the Dim in the If statement but since I can't use it outside of the if the rest of the code has no definition.

Private Sub frmCJ_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim dsOrg As DataSet
If m_ConnectionString = "prod" Then
Dim wsrv As New seoweb.Service1
dsOrg = wsrv.CJGetOrganization

Dim DV As DataView = dsOrg.Tables(0).DefaultView
With cbOrganization
.DataSource = DV
.DisplayMember = "organization"
.ValueMember = "organization"
End With
Else
Dim wsrv As New seodev.Service1
dsOrg = wsrv.CJGetOrganization

Dim DV As DataView = dsOrg.Tables(0).DefaultView
With cbOrganization
.DataSource = DV
.DisplayMember = "organization"
.ValueMember = "organization"
End With
End If
End Sub
