How can I know the length of an dynamic array in VB?
For example:
a = split(s,"|")
a.length???

UBound(a) + 1

Hi
I load a picture (bmp) into a picture control.
The picture control have AutoSize on true and the picture is bigger then the screen.
I need to check the color of every pixel.
With picture.point (x,y) I have access only to the region on the screen (otherwise return -1)
How can I check the color of all pixels?
Thanks

make picture1.AutoRedraw=True
this worked but the problem is that autoredraw property consumes alot of memory I think.

Anybody know of a way to create a new instance of a form if you only know the name of the form?
Right now i'm doing a huge hack... a big select case statement.
there has to be a better way!?!?!

Could you give us a better idea of what you are doing exactly. There are ways to create new forms programmatically.

aight, here's the deal...
on the left, I have a treeview that holds a bunch of nodes which represent forms to open. They hold the name of the form as a string as their key.
when somebody clicks on a node, it should open a new instance of the form, by name.
If there is a better overall way to do the same effect, that'd be fine as well.
The basic gist of what I want is a list of the form's which can be shown, and to make a new one when the user clicks on it. It is possible to open more than one of the same form at a time.

Dim myForm as Form<br />
Set myForm = new Forms("MyFormName")
I've seen something similar to that, but I don't have VB 6 installed so I can't check it.
Should give you a start anyway,

hrm
the Forms collection only shows forms which are already loaded. besides, I don't think I'd be able to create a _new instance_ with this method.
also, the New Forms("MyFormName") syntax doesn't compile.
I even tried a CallByName hack ( Set myForm = CallByName( App, "MyFormName", vbGet ) ), but that didn't work either.
any other ideas?

My problem is both simple and complex...
I am writing an RS232 protocol layer that was meant for Visual C++, however now the boss man wants me to integrate it in to Visual Basic. So I decided to convert the static library to a DLL. Everything seems to work fine, and from the outside the IDE all the visual basic apps run well. However inside the IDE, after running, the VB IDE has many problems. On my machine it only causes an application error on exit. On others, it causes application errors at random times. I thought maybe I was trashing the stack, but my DLL is not doing it. I am thinking it is the arguement passing...
These are my definitions in the DLL..
[code]
#define INCOMMSTACK_API extern "C"
INCOMMSTACK_API long WINAPI Initialize (long lHwndOwner);
INCOMMSTACK_API long WINAPI ExpediteMessageByte (LPBYTE pbMsg, DWORD cBytes);
INCOMMSTACK_API long WINAPI ExpediteMessageText (LPCTSTR szMsg, DWORD cChars);
INCOMMSTACK_API long WINAPI SendMessageByte (LPBYTE pbMsg, DWORD cBytes);
INCOMMSTACK_API long WINAPI SendMessageText (LPCTSTR szMsg, DWORD cChars);
INCOMMSTACK_API long WINAPI SetRetryCount (DWORD dwRetryCount);
INCOMMSTACK_API long WINAPI SetTimeout (DWORD dwTimeout);
INCOMMSTACK_API long WINAPI SetProtocol (DWORD dwProtocol);
INCOMMSTACK_API long WINAPI ConnectRS232 (int iCommPort, int iBaudRate);
INCOMMSTACK_API long WINAPI ConnectUDP (LPCTSTR szAddress, int iPort);
INCOMMSTACK_API long WINAPI CloseConnection ();
INCOMMSTACK_API long WINAPI GetReceivedMessage (LPBYTE pbByte,
DWORD cBytes,
DWORD wParam,
long lParam);
[/code]
and these are the declaration in VB...
[code]

I included the win32 calls for handling the WM_MESSAGES that the static library used to communicate to the frame in the VC++ implementation.
Any ideas on what might be happening or am I just wading in hot water with no raft....
Thanks,
Brian

Hi,
I use VB6 & SQL Server. My database is saved in a server. The operating system in the server is Windows NT that supports only English Language, and my data, which I need to save, is written in Arabic.  The problem is that the data saves as garbage.
Note: There is no problem with Visual C in the same database.

Hi,
I've solved my problem by adding this statment "Auto Translate=False" to the "ConnectionString".

is it possible to run a activeX control (OCX) from a server side without the client downloading it. just like using asp and activeX dlls?

If you are on a local network you could use DCOM to instantiate the object on the other machine. Otherwise I would recommend turning to something like SOAP to run objects on a server over the internet.
SOAP is a protocol that allows you to communicate through the firewalls and such that are located on internet servers, by simply using XML.
