I hope you can help me.

Let me explain then.

I have three fields in this form. First is for a category, the second one is the subcategory (should be based on the first one), and the third one is the type (based on these previous two). Yet, there is also a fourth field, since we are talking about a incident form, that is the assignment group. Based on selected options on the first, second and third fields, the fourth (group) field is automatically populated with the destination group.

Today, I have this form only with blank fields. I can type anything I want on them. If the category, sub category, type, and group exists in the system, it will be accepted, the form will be submitted, and the incident will be created successfully. Otherwise, the incident will have missing fields or will be ambiguously created, if there is a typo or if there is any different word that is not in the system.

So, I need something like a dropdown menu in each first, second and third fields, and the fourth field must be displayed automatically based on the combined selection of these first three. Are you following me? Hope so!

Also, if possible, and preferably because it will be better for future updates, I wish to get these fields populated based on a external txt or a excel file, or else, if I incorporate these entries on this vbscript, it will become huge and maybe heavy.

Finally, each category (1st field) entry (in the excel/txt) should be associated to a ID. So should be the subcategory (2nd field), and the type (3rd field). Which means, a category name is displayed, but behind there is a ID associated, and when submitting the form, the ID is the one that will be sent to the system (hope I am being clear). So this information Category and ID, for e.g, will be available and will be collected by the form, from to the external file.

So, below is a video showing a working drop down menu incident form submition, just the way I am looking for. The file is in SWF (flash format), so you can open it with internet explorer or with flash player.

The actual and working VBscript is also available on the link below.

Thanks for all your help.

Capturing a Picturebox in Windows 8

I have the following code which works on windows 7 but when I run my app on windows 8 I just get a black box. I am using VB6
and have seen several capture submissions here but they all do the same thing (or at least the several I have tried.

Here is my code

Public Function CaptureWindow(ByVal hWndSrc As Long, ByVal Client As Boolean, ByVal LeftSrc As Long, ByVal TopSrc As Long, ByVal WidthSrc As Long, ByVal HeightSrc As Long) As Picture
  
    Dim hDCMemory As Long
    Dim hBmp As Long
    Dim hBmpPrev As Long
    Dim hDCSrc As Long
    Dim hPal As Long
    Dim hPalPrev As Long
    Dim RasterCapsScrn As Long
    Dim HasPaletteScrn As Long
    Dim PaletteSizeScrn As Long
    Dim LogPal As LOGPALETTE
  
    On Error Resume Next
  
    If Client Then
        hDCSrc = GetDC(hWndSrc)
    Else
        hDCSrc = GetWindowDC(hWndSrc)
    End If
    hDCMemory = CreateCompatibleDC(hDCSrc)
    hBmp = CreateCompatibleBitmap(hDCSrc, WidthSrc, HeightSrc)
    hBmpPrev = SelectObject(hDCMemory, hBmp)
    RasterCapsScrn = GetDeviceCaps(hDCSrc, RASTERCAPS)
    HasPaletteScrn = RasterCapsScrn And RC_PALETTE
    PaletteSizeScrn = GetDeviceCaps(hDCSrc, SIZEPALETTE)
    If HasPaletteScrn And (PaletteSizeScrn = 256) Then
        LogPal.palVersion = &H300
        LogPal.palNumEntries = 256
        GetSystemPaletteEntries hDCSrc, 0, 256, LogPal.palPalEntry(0)
        hPal = CreatePalette(LogPal)
        hPalPrev = SelectPalette(hDCMemory, hPal, 0)
        RealizePalette hDCMemory
    End If
    BitBlt hDCMemory, 0, 0, WidthSrc, HeightSrc, hDCSrc, LeftSrc, TopSrc, vbSrcCopy
    hBmp = SelectObject(hDCMemory, hBmpPrev)
    If HasPaletteScrn And (PaletteSizeScrn = 256) Then
        hPal = SelectPalette(hDCMemory, hPalPrev, 0)
    End If
    DeleteDC hDCMemory
    ReleaseDC hWndSrc, hDCSrc
    Set CaptureWindow = CreateBitmapPicture(hBmp, hPal)
   
End Function

Any help in changing or making it work on windows 7 & 8 is much appreciated
