Register dll (delphi) forms 6i?

I have an application in developper 6i. A applicattion's proccess calls a function from dll (using ora_ffi), but when i try to run the process, it failed.
I don´t know if i need to register the dll in forms or something like that? the dll is localized on forms_path
I work with windows NT and XP?
have you any idea?

Hi Nilakshak,
In Visual Basic you could make ActiveX DLL and you could call it from Forms client/server using OLE2 package.
See: http://www.tigralen.spb.ru/download/vb_dll.zip, http://www.tigralen.spb.ru/oracle/vb/index.htm.
I think it helpful for you
Thanks

Swing Form = JNI = Delphi DLL = Delphi Form works but small issue

Hi all
I'm trying to call a delphi dll from a java form.
This is the procedure
swing button action => jni => call procedure in delphi dll => create delphi formThis works for me but the problem is when click the button it create the delphi form by calling the dll but it's stucked for ever(frame not the whole form). Never return to do something else. Means that it's stay remain in clicked postion.
I do not know whether the problem exist with the swings' single threaded behavior. I have used another thread to call natives. But the problem persist.
So can any one suggest any answer.
Wish U all HAPPY NEW YEAR!
Here is the compact code
native calls
public class LoadLib
    public native void createForm();
    public native void forward();

Hi deshan,
To realize the problem you should know principles of Java GUI (SWING or AWT) implementation in JVM:
1) Java GUI is implemented in a single thread with EventQueue static object, which is created with JVM when Java Application GUI starts.
2) Any painting or event calls are done on this thread (the same approach was used by Microsoft in .NET GUI).
3) While your code handles an event EventQueue waits for return from your event method. Some calls to GUI components can stick the whole Java GUI (this is the problem of SUN Java architecture, I did not have this in Microsoft Java). To avoid this problem you should use InvokeLater method that works like PostMessage to the main thread in Windows Application. InvokeLater generate an event that is posted to EventQueue and your code passed to InvokeLater method will be executed asynchronously in GUI Thread.
4) If you call any Java (SWING or AWT) component from the thread other than EventQueue thread you must synchronize these calls with locks by the object got from getTreeLock() method of the component you call. But you should be accurate with locks because they can cause deadlocks.
Your code does not return from Click Event where you try to create some GUI component but EventQueue is still waiting for return and the main GUI thread is suspended.

How to register a custom form under "LEASE -- TOOLS"?

Hi,
This is my first form development in Oracle Apps.
I have a requirement of building a custom form and to display it under LEASE -- > TOOLS.
I could register the form under a menu by the following steps:
1. Application Developer --> Forms : Enter the custom form name
2. Register a new form function
3. Attaching the form function under a menu
How do I register this form under Lease--> Tools?
Thanks and Regards
Ruma

Hi,
I could register the form under a menu by the following steps:
How do I register this form under Lease--> Tools?I believe you could follow the same steps but attach the form function to the submenu (instead of the menu itself).
From the Application > Menu, query the main menu to get the submenu, then query the sub-menu and attach the form function.
More details can be found in the "Developer Guide" which can be found at:

How to call a function of registered DLL in Diadem8.10?

Please make the entire procedure after registering DLL in Diadem8.1. Notably, i can't use LAbview. I need it in VBS file. Can you put a sample code example, as i already exhausted in searching the help.

Hi mv_rajk,
I have to agree with IS that I'm not completely sure what you want either. But I'd like to round out IS's excellent points with two more:
4) VBScript can create object variables from an ActiveX object file (*.ocx) and call methods and read and write properties of the new object variable natively. So you can call a DLL from VBScript, but only if you first wrap that DLL in an ActiveX layer and create an object variable with the CreateObject() command.
5) VBScript can similarly create an object variable for any application's OLE Automation Server, again with the CreateObject() command. So you can absolutely call a LabVIEW VI from a DIAdem VBScript, and you can pass DIAdem channels to the VI and create new DIAdem channels based on the
outputs of that VI. Note that this works with all LabVIEW inputs and outputs EXCEPT clusters. So you might have to wrap the VI you're interested in in another VI that builds the clusters to send to the VI you want or unpacks the clusters you get back from the VI you want.
If either of these points sound interesting to you, we'd be happy to provide VBScript code and examples.

Register HR custom forms.

Hi
Is it recommend to register custom forms on seeded product application and put the fmx files in seeded product folder. Or should all custom forms should be put in custom folder. I need to register custom HR forms.
thanks
sva

Hi,
Are you going to create a custom schema? If yes, it is recommended you create a new CUSTOM_TOP and place all the files under this directory. If no custom schema is required you can register those custom forms/reports under the product application, just make sure you follow a naming convention to identify your custom objects/files from the seeded ones -- Please see the docs referenced in this thread for details.

Calling a dll from forms 6

Hello,
Sorry, I'm brazilian and my english isn't very good...
I'm trying to call some functions from a dll invoked by a trigger on event WHEN-BUTTON-PRESSED. I make a package as this:
---- Package Spec ----
PACKAGE anserlib IS
     function autoconnect(p_connport in number) return boolean;
END;
---- Package Body ----
PACKAGE BODY anserlib IS
     libhandle ora_ffi.libHandleType;
     autoconnect_fhandle ora_ffi.funchandletype;
     setprinton_fhandle ora_ffi.funchandletype;
     setprintoff_fhandle ora_ffi.funchandletype;
     res varchar2(200);
     commport number;
     function ff_autoconnect(fhandle ora_ffi.funchandletype, p_commport in number) return boolean;
     pragma interface(C, ff_autoconnect, 11265);
     function autoconnect(p_connport in number) return boolean is
     begin
          return(ff_autoconnect(autoconnect_fhandle,p_connport));
     end;
begin
     libhandle := Ora_Ffi.Load_Library('C:\Juarez\Anser\','Anser712.dll');
     autoconnect_fhandle := ora_ffi.register_function(libhandle,'AutoConnect');
     ora_ffi.register_parameter(autoconnect_fhandle, ora_ffi.C_INT);
     ora_ffi.register_return(autoconnect_fhandle, ora_ffi.C_INT);
     setprinton_fhandle := ora_ffi.register_function(libhandle,'SetPrintOn');
     ora_ffi.register_return(setprinton_fhandle, ora_ffi.C_INT);
     setprintoff_fhandle := ora_ffi.register_function(libhandle,'SetPrintOff');
     ora_ffi.register_return(setprintoff_fhandle, ora_ffi.C_INT);
     ora_ffi.generate_foreign(libhandle, 'anser');
exception
     when ora_ffi.ffi_error then
          --message(:bloco_teste.mensagem, acknowledge);
          message(tool_err.message, acknowledge);
END;
and the trigger is:
declare
     v_res boolean;
     v_commport number;
begin
     v_commport := 3;
     v_res := anserlib.autoconnect(v_commport);
end;
When I run the form and press button appears the message (it appears in portuguese to me, maybe the text is not the same in english, but i'll try to translate):
FRM-40734: Internal Error: occours a PL/SQL error.
Someone have an idea to help me...?
Thanks vry much!!! :)

In my opinion this error is something like 'General Protection Fault error' in Windows. I sow this error when my DLL worked with memory incorectly or called OCI functions which don't work under Forms Runtime.
I think the problem might be caused by a mistake inside the DLL. The other problem may be that you use incorect calling conversion. For instance, the default calling conversion in Borland C Builder or Delphi is fastcall, not cdecl.
p.s.
1. Sorry for my English too :).
2.
ora_ffi.generate_foreign(libhandle, 'anser');I'm not sure what ora_ffi.generate_foreign does exactly, because I have never used it. As far as I know it isn't needed for this code. I'd recomend you to remove this line from your program.

How to use a custom.dll in forms 6i

Hi,
i have made a small dll using a icon-making software, that software has made a .dll of the icon I made in that software
Now i want to use that .dll in my forms 6i. (client/server)
the dll contains only one icon named 'Icon1'
would any one please tell me how can I call that icon in that .dll to view in my forms button at run time..
is this possible..??
just for clarification, for security reasons I am not using the .ico of that icon diect from hardisk in my button thats why i made a .dll of that so that the user may not be able copy my icon
thanks in advance,

Here is the doc
Doc ID:      Note:99824.1
Subject:      How to Display User-Defined Cursors and Icons in Forms
Type:      BULLETIN
Status:      PUBLISHED
     Content Type:      TEXT/X-HTML
Creation Date:      23-FEB-2000
Last Revision Date:      30-OCT-2002
PURPOSE
The purpose of this note is to explain how to display customized
cursors and icons in Forms 6.0 on Windows platform (32 bits).
Assumption is made that resources are stored in a DLL, which is
available in the path at runtime.
It is mandatory to store the cursor in a DLL to make it available
with Forms: .cur cursor files cannot be directly loaded from the
file system.
On the other hand, icons .cio files can directly be read from the
filesystem by Forms Runtime. However we will focus on icons which are
stored in a DLL.
The article is divided into two main parts:
- how to build a resource-only DLL with Visual C++ 5.0
- how to display the cursor and the icon in Forms 6.0
SCOPE & APPLICATION
The intended audience needs to have basic knowledge in Forms Builder
and also in Visual C++ (or any other Win32 compiler).
A typical environment is Forms 6.0, Visual C++ 5.0 and Windows NT.
WHAT IS A RESOURCE ?
A resource can be considered as some extra binary information that can
be added to an executable file. Windows resources are for example icons,
cursors, menus, dialog boxes, keyboard-accelerator tables and much more.
Resources are usually stored in a .rc file, which is compiled by the
resource compiler in order to provide a .res file. These compiled resources
can then be appended to a binary executable file or a DLL.
For instance, Visual C++ 5.0 includes a resource editor which allows you to
draw your icons and your cursors, and store them in a resource file.
Part I - BUILDING A RESOURCE-ONLY DLL
Consider the following setup:
- myicon.ico: icon file
- mycur.cur: cursor file
The objective of this section is to build a DLL called proj.dll which
contains both the icon and the cursor. This operation requires several steps.
Step 1: Create a project
In Visual C++, select menu File->New... In the dialog box, choose the Projects
tab and pick "Win32 Dynamic Link-Library". Fill the project name (e.g. Proj)
and the location (e.g. c:\MyProjects). Check 'Create new workspace', check
Win32 as target platform and click on OK.
This creates a directory c:\MyProjects\Proj, where necessary .rc and .cpp
files can be stored. Place the .ico and .cur files in this directory too.
Step 2: Add a resource file to the project
Create a proj.rc file, edit it and make sure it contains the following lines:
testcur CURSOR DISCARDABLE "mycur.cur"
testico ICON DISCARDABLE "myicon.ico"
This is the resource file. Using the Project->Add to Project->Files... menu,
select the proj.rc file and add it to the current project.
Step 3: Add a dummy C++ file to the project
Create a proj.cpp file, edit it and make sure it contains the following lines:
#include <windows.h>
extern "C"
BOOL WINAPI DllMain (HINSTANCE hInstance, DWORD dwReason, LPVOID)
     return 1;
This creates an entry-point in the DLL. This function does nothing but is mandatory
to have a DLL after the build of the project.
Add the proj.cpp file to the project as described in Step 2.
Step 4: Choose the target type
At this moment, you can choose if you need a 'DEBUG' or a 'RELEASE' flavour of
the DLL. As there is not much to debug in this DLL, the 'RELEASE' flavour is
recommended. Furthermore, it is much more compact.
Using the Build->Set Active Configuration... menu, choose the Proj - Win32 Release
as the active configuration.
Step 5: Build the DLL
Now, it is time to compile the resource file, compile the C++ file, link both
together and build the proj.dll DLL. This operation is performed by using the
Build->Rebuild All menu.
After a short time, you should see "Proj.dll - 0 error(s), 0 warning(s)" in
the Visual C++ message window. This means that the DLL was built successfully.
Step 6: Place the DLL in the appropriate directory
The proj.dll file is currently located under the c:\MyProjects\Proj\Release
directory. Copy it in an appropriate directory which is reachable in the
runtime environment path.
Part II - USING THE ICON AND CURSOR IN THE FORM
At this stage the DLL is created and can be used in the Form application.
Again, this is a multi-step procedure.
Step 1: Load the DLL in the Forms Runtime environment
Assuming the proj.dll DLL is placed in a directory pointed by the
PATH environment variable, below is the piece of PL/SQL code which loads
the DLL into the Forms Runtime environment. This code can be placed in the
WHEN-NEW-FORM-INSTANCE trigger for example:
declare
     hDLL     ORA_FFI.LIBHANDLETYPE;
begin break;
     --Preload the DLL so the cursor and Icons can be found.
     -- I'm assuming the DLL is in the path here
     hDLL := ORA_FFI.LOAD_LIBRARY(NULL,'proj.dll');
exception
     when ORA_FFI.FFI_ERROR then
          for i in 1..TOOL_ERR.NERRORS LOOP
               message(TOOL_ERR.MESSAGE(i));
          end LOOP;
end;
Step 2: Display the cursor stored in the DLL
Now, you may want to change the cursor when the user clicks on
a specific button. This is an example of code that could be set
in the WHEN-BUTTON-PRESSED trigger:
set_application_property(CURSOR_STYLE,'<proj>TESTCUR');
<proj> refers to the proj.dll. Please note the < and > signs
which are mandatory there. TESTCUR is the name of the cursor resource
as defined in the proj.rc file.
Step 3: Display the icon stored in the DLL
You may also want to change the icon of an iconic button after
some specific end-user action. The appropriate code for that is:
set_item_property('IBUTTON',ICON_NAME,'<proj>TESTICO');
IBUTTON is a PushButton, with the Iconic property set to Yes.
TESTICO is the name of the icon resource as defined in the proj.rc file.

Hi,
We have the same problem in our project . In this case we are upgrading from an older version of forms (3.0) to 6i. The UE worked fine in the older version, but now we get a NON ORACLE ERROR. Our DLL is written in MS-VC++ project.
We'd like to know whether , besides the common version and platform, you have also written the DLL using MS-VC++ ; otherwise please tell us .

i uesd JACOB project for this dll
please i need help as i don't know a lot about registry
thanks alot

The program can't start because ftd2xx.dll is missing from your computer. Try reinstalling the program to fix this problem.
Newly installed program on fairly new Windows 7 laptop. First time running it and we are missing .dll files. The google is full of very malicious looking websites offering dll files.
Not sure where to go on this one except bothering the vendor. I've seen Microsoft articles with no helpful information as well.

Invoking a VB executable /DLL from Forms 6i

Hi Everyone,
We have a complete application (in the form of a product) in
Forms 6i. We need to integrate a licensing software with this
Forms product. This licensing software is built in VB. We
basically need to execute an executable and a DLL - ( I presume
that i can execute any external application/exectuable using the
HOST function ) - Please confirm if this can be done. And more
importantly how do I invoke a DLL which is supposed to return a
value to the Forms application.
All inputs are welcome - This is really really Urgent.
Ipsa.

I think you can use the ORA_FFI (Foreign Functions Interface) to
invoke functions in a DLL. I recently put together a small
package for calling HTML Help files using ORA_FFI. I can send it
to you if it would be of any help.

Registering DLL's

I have an application in VB 6 with Crystal XI as the back end reporting. Everything installed fine but when the user tries to run the reports they get the error "Run-time error u2018339u2019 Component u2018Crystl32.ocxu2019 or one of its dependencies not correctly registered: a file is missing or invalidu201D. I have had the customer go through and register all the dll's that are listed for Crystal. The part that I can't seem to figure out is that if they are logged in as an administrator, the application runs fine but when they log in as an user, they get this error when trying to run the reports. Do they need to do something special for the user to run the reports?

Hello Lisa,
Since you're having an issue with one of the older Crystal runtime components you'll want to move this post to the "Legacy Applications" forum under the "Crystal Reports and Xcelsius" group.
If the application works correctly when you're logged in as an administator, but not as a regular usuer this suggests an issue with registry access. It sounds like the regular user doesn't have rights to access the registry. This may be because when the application was installed it wasn't installed "for everyone."
You can confirm registry access issues by using a utility called RegMon. It's part of the Sysinternals Suite, and it's available on the Microsoft website.
After addressing the registry permission issue the application should start working for the user.
Sincerely,
Dan Kelleher

Register dll on client side through applet

hi
can any on e tell how to register a dll on client side from a signed applet.
thanx

I am not very sure. But you can try this:
public class Dialup {
public static void main(String[] args) throws Exception {
Process p = Runtime.getRuntime().exec("register_dll.bat");
p.waitFor();
System.out.println("Done.");
where register_dll.bat is your dll registration (regsvr x.dll)
Let me know if this works
