didn't notice that 
I tried now with ByRef, same result 
SetSystemTime() is really called, but time changes to 31-12-2007 00:00 which means that it's not passing parameters to the function?

Where did you get your SYSTEMTIME Structure? It is completely wrong.
Check the documentation, stop your trial-and-error methods.

You should be passing the structure in ByRef AND you've defined all the fields in the structure as Integers (32-bit signed). They should be Shorts or Int16, 16-bit signed numbers:
Private Structure SYSTEMTIME
Public wYear As Int16
Public wMonth As Int16
Public wDayOfWeek As Int16
Public wDay As Int16
Public wHour As Int16
Public wMinute As Int16
Public wSecond As Int16
Public wMilliseconds As Int16
End Structure
WORD types in the documentation convert to Int16's (Short). DWORD's convert to Int32's (Integer).

Hi,
you probably need to call function GetDiskFreeSpaceEx() in kernel32.dll
Another question by VIP Commando, right above this one, would show you how
these things can be done.

thankx buddy for reply,
but the real problem is it returns the free space in Numbers of Bytes if there is HDD capacity more than 200GB then VB 6.0 fails to accept the range and throws the exception as "Sunscript outof range OVERFLOW"
what should i do ?
i have tried with "Long" and "Double" Type

Hi koolprasad2003,
I found this (put in in a new form ...)
Private Declare Function GetDiskFreeSpaceEx Lib "kernel32.dll" Alias _
"GetDiskFreeSpaceExA" (ByVal lpDirectoryName As String, _
lpFreeBytesAvailableToCaller As ULARGE_INTEGER, lpTotalNumberOfBytes As _
ULARGE_INTEGER, lpTotalNumberOfFreeBytes As ULARGE_INTEGER) As Long
Private Type ULARGE_INTEGER
LowPart As Long
HighPart As Long
End Type
Private Sub Form_Load()
Dim result As Long
Dim x As ULARGE_INTEGER
Dim y As ULARGE_INTEGER
Dim z As ULARGE_INTEGER
result = GetDiskFreeSpaceEx("c:\", x, y, z)
Debug.Print result
Debug.Print x.HighPart, x.LowPart
Debug.Print y.HighPart, y.LowPart
Debug.Print z.HighPart, z.LowPart
End Sub
Greetings, Thomas

You normally define a hotkey to launch your application in the shortcut to the application, not in the application itself.

Hello everyone!
I am interested in building a gantt chart component in vb .net. I've been around and saw alot of third-party components that are really good but the problem is I dont want to buy them but instead I would want to build one myself. It wouldn't have to be as great, just a basic one will do.
Given that there is many third party components out there, im conviced that it can be done! So in order to go ahead and build one, I assume i'll have to build a custom control, acquire knowledge in GDI+ and inherit and manipulate the datagrid component?
In my opinion, the Gantt Chart component should have the elements of rows and columns; rows so that bars can be in placed accordingly, the bars will be representing the duration for each task and the columns to represent a timeframe. The bars may consist of lines that will connect these bars with one and another to represent dependencies. Thus suggesting a line to be drawn thru GDI+ i suppose?
So with the basics of what im trying to create here, im pretty much clueless on how I'm going to go ahead and build one as I never build a custom control before.
I really want some suggestions on this...is there another way of building a Gantt Chart? Or am I heading off the wrong direction? Or have I got it all just plain wrong. =(
Hope someone can assist me! Thanks in advance!
Jensen
Here are some links to those third party components I was refering to;

So far, so good. Though, I'd forget the DataGrid stuff and just draw the entire control using GDI.

You've picked a very LARGE one to start with. I'd recommend not doing this until you've gone through some smaller controls to get the basics of how controls work, drawing, managing your controls state, managing data, databinding support, and the relationship between your data model and drawing it.
Your control is going to have to track a bunch of data and do a ton of math to figure out how it's going to draw itself, positioning text, bars, grid lines (if any), ... Start small and work your way up.

You're going to have to try adding the COM components to the toolbox in VB6 and try it yourself. Usually, once people go to VB.NET, they don't go back to VB6 (unless absolutely forced to.)

in my project, i use toolbar toolbar in my buttons...i used case structure for the functions of each buttons in the toolbar but theres an error in it...
my codes goes like this:
Select Case<br />
Case 0<br />
Dim subjects As New subjects<br />
subjects.Show()<br />
Me.Hide()<br />
Case 1<br />
Dim file_maintenance As New file_maintenance<br />
file_maintenance.Show()<br />
Me.Hide()<br />
Case 2<br />
Dim grade_entry As New grade_entry<br />
grade_entry.Show()<br />
Me.Hide()<br />
End Select
is this code correct???
or this:
dim keyin as integer <br />
Select Case keyIn<br />
Case 0<br />
Dim subjects As New subjects<br />
subjects.Show()<br />
Me.Hide()<br />
Case 1<br />
Dim file_maintenance As New file_maintenance<br />
file_maintenance.Show()<br />
Me.Hide()<br />
Case 2<br />
Dim grade_entry As New grade_entry<br />
grade_entry.Show()<br />
Me.Hide()<br />
End Select<br />
in the first code, there is an error so i can't run my program...
in the other code, the 1st button is only functioning...
what is the really correct code for this???
|
|
|
|
|
in the first case statement:
Rharzkie wrote: Select Case
This should be Select Case myVariable where myVariable is the variable you are referencing to.
The second one seems fine, there must be an issue in the way the keyIn is changed, it must not be being changed when the other buttons are pressed.
|
|
|
|
|
but when i used the 2nd codes, the first button is only functioning...in the other button, the function also same as the ist button (it should not be the same)...in short, case 1 in only functioning but the others did not...what's wrong with that???
|
|
|
|
|
like The ANZAC said the second case looks to be correct the problem may lay in how you change you're variable keyin
perhaps debugging the project and looking at when the keyin variable is changed or not changed will help you further
from the behavior you described my guess would be that the keyin variable isn't changed therfor the same code is excecuted for all buttons

That is all.
