This sounds like a design issue where you want to validate the content of a field and inform the user. There are various validation frame works, depending on the UI platform you are working with.
Or you could put a label on your UI and populate it with an error message, or you could pop a messagebox and get in the users face or you could wait until the user has completed the entry and tell him each mistake made if there are multiple entries.
Some idea what UI you are using would refine the answer somewhat!

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.
Best regards!

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

VB6 went out of support years ago, you should upgrade to VB.NET.

Thanks for your response. I agree with upgrading to .NET but that is not always possible when you have several projects with millions of lines of code.
Not everyone has the luxury or rewriting or upgrading all their code. I was asking if there was a solution to a very specific problem.

Very true, but if you cannot or will not upgrade then you are going to have problems running something as old as VB6, especially on the newer versions of Windows.

I understand that. But wouldn't that be the answer to every question posted in this group? This group is for VB. There is another group for .net correct?
|
|
|
|
|
No, this forum is mostly for VB.NET, most people have long ago given up VB6, for the reasons I mentioned.
|
|
|
|
|
That would be my mistake then.
|
|
|
|
|
Here's a simple suggestion: rewrite the above code in VB.NET and see what the results are.
|
|
|
|
|
You wouldn't do it that way at all in .Net....

Well obviously. But that is not what the issue is about.

No VB6 is not recognised here as a viable product, this forum is targeted at VB.net. I can only thank the great Ghu I don't have your job! My sincere sympathies.
While most of the people supporting here probably have VB6 back in the past all of them have moved on so help is going to be very limited. It is well past the time for a rewrite, it is no longer a luxury it is critical.

My mistake then about this group.
|
|
|
|

The problem you're going to have asking questions about VB6 is that very few people still have it installed to test the code and come up with a solution! This is going to be true at ANY forum, unless it's specifically dedicated to VB6.
|
|
|
|
|
OK OK! I get it! Don't ask questions. Done and Done.
|
|
|
|
|
There's nothing wrong with asking questions. But you need to understand that using a programming language that is years out of date is going to be difficult for people to answer. Also, that the later versions of Windows use features that VB6 was never designed to handle.
|
|
|
|
|
I understand about it being out of date. I also know there are a lot of people still programming in VB6. When a whole product works except for 1 feature it is difficult to justify the cost of totally re writing an app.
I feel like I asked a simple question just to get bashed because of the language. If people do not have an answer why be little someone for asking a question.

No one has belittled you. We are just trying to get you to understand that VB6 is so long out of support that almost no one (particularly on this forum) uses it any more. The problem you are seeing may well be due to the fact that you are trying to use very old libraries and code on a much later OS which uses many new features. I have given you one suggestion to try and isolate whether the problem is definitely due to VB6, and you could save some time by trying it.

gwittlock wrote: just to get bashed because of the language
I don't think any of us were belittling you, we have all used VB6 in the past, I doubt the VB6 is your choice and I can understand supporting legacy code. While it maybe a single feature that has failed now the problem is only going to get worse as the OS moves forward and you are stuck in the 90s, alright early 00s.
You should have had a migration plan in place 10 years ago if it is part of your core business (millions of lines of code indicates it is a major commitment).
To give you some perspective, MS have announced the sun setting of Silverlight in 2020 (I think) we are looking at rewriting 34 applications into either MVC or WPF and yeah possibly as much as 1m LOC.

I never said "don't ask questions". I just told you why you're going to have a hard time getting an answer to it.
It's not just "a simple question".

I want to thank everyone for their responses. As a matter of fact Richard has helped me out before with I question I asked about .net and I greatly appreciate it.
I do program in .net and have done so for awhile. All of may main products have be upgraded as some suggested here.
I do believe my question was detailed, I provided the particular code that I believed was the issue and did explain the issue I was having.
It is probably my fault for this question getting off track. Just as much as ask the right question, answering the question should be just as important. If someone has an answer that is great. That is what these forums are for IMO anyways.
Saying you should upgrade the code to .net doesn't answer the question (at least I do not think so because that is certainly the way to go. If you can justify the cost VS benefit). Maybe I asked it in the wrong forum. I agreed that programming in VB6 was not the greatest but it is what I had to work with. I was hoping that someone else had encounter the same issue. Here another way of looking at it. You have lived in your house for 10 years and you discover a leak in your plumbing. Now the plumbing is not the latest and greatest technology. Do you replace all of your plumbing? Do you say that the plumbing is 10 years old so you should buy a new house? Of course not. (No sarcasm intended here. Just trying to relay an analogy). You just fix the leak I am sure.
As I said this question got a little off track, so again I want to thank everyone for their input it is always appreciated

The number of responses you received suggest that no one has. Have you tried that code in VB.NET as I suggested, just to see if that really is the issue?

You did not even replace a part with something newer when it was broken, you waited until it became obsolete in the industry.
So, you already new that your 10 year old house was using an out of date plumbing, and went ahead with it because it is cheaper. You have chosen to become obsolete. And yes, I will keep hammering that point, because someone else "might" think that your argument is valid.
It was, 2004. Not in 2014.

On the Windows 7 computer that works, have you disabled Aero? It sounds like your code doesn't work with layered windows.
Most Google results seem to suggest that you need to pass the CAPTUREBLT flag (&H40000000L) to the BitBlt function[^]. It's not declared in the RasterOp enum[^], because VB6 came out a long time before Aero, so you'll need to declare it yourself.
My VB's a bit rusty, but something like this should work:
BitBlt hDCMemory, 0, 0, WidthSrc, HeightSrc, hDCSrc, LeftSrc, TopSrc, CLng(vbSrcCopy Or &H40000000L)
Edit: Forgot that VB6 uses Long for 32-bit integers.
