A DLL dependency issue maybe? You might want to verify that all the dependent DLLs that your add-in requires are present on the client's machine.

Im working on a small project, mainly just a "can i do it".
I have a project in VB6, and i want to write a C++ ocx with managed code to call some C# functions, so basicly kind of like a wrapper.
While im sure i can pass data from vb6 to C#, i want to know how i can call functions in a VB6 class from c#
i was thinking that i might need to do something like this:
Pass Object from VB6 to c++ ocx file.
In C++, look at functions and make a list and send that to c#
When c# wants to run a function, it says to C++ to run X function.
C++ then runs that function in the class file.
Note that i havn't done anything remotly like this, and i don't even know exactly what exactly to ask for. Any tips would be nice

Let me get this straight - you want to create a native OCX using managed C++ so you can call C# functions from a VB6 project? Whoa! That's kind of taking interop to the extreme isn't it?!  Just kidding!
Seriously though, why are you proposing to have a C++ middle-man to liason between the VB6 component and the C# code? Can you not just create an ActiveX DLL using VB6 and use interop to invoke it from C#? And for invoking the C# code from VB6, use "TLBEXP" and "REGASM" to export the .NET class as a COM component.
Shouldn't you just be able to use .NET interop as the middle-man brokering calls?

I did try something like that once, but for some reason, it never liked to work right.
all of the examples ive seen with .net COM stuff were for web pages, and didn't work well, or at all, for VB6
like i said, i don't really know what im doing, i was hopeing someone could guide me.

For an application running on two separate machines I use DCOM to communicate. On system 1 a CoClass exists, hosted in a COM server which acts as a singleton (using DECLARE_CLASSFACTORY_SINGLETON ATL). This CoClass is created from system 2 through DCOM, but also local by system 1.
Despite using the singleton classfactory still two instances of the CoClass exist in running server (one for all local system 1 clients, and one for all dcom clients). I've tried changing a number of security settings through DCOMCnfg but this didn't help (sometimes even ended up with two servers next to each other  ).
Strange thing is that when the CoClass is first created through DCOM and later by the local user it all seems to work. The other way around however always creates two instances. Unfortunately both systems can be switched on or off seperately so the starting order isn't defined.
Current settings are:
Authentication Level - Connect
Impersonation Level - Identify
Identity - This user (same user as the local on system 1 also CoCreating the CoClass)
Both systems are using Windows XP SP2.
Anyone got any idea on why this doesn't work ( and hopefully knows how to solve ) ??

Rem Demonstration File
2. List the files in the A:\temp directory

3. Display the contents of a file in the a:\temp directory that is specfied when the batch file is called.
( This is were i have some questions)
Type %1 (is this correct?)

Hi,
I have created a fully editable data using template columns for using it for data entry and editing.Can some one help to validate the data entered into the grid and also check for duplicates. I am reading all the data from the datagrid into a typed dataset for saving into database so essentially I need to check for duplicates in the dataset. My datagrid contains 2 columns and each column is a textbox to enter data.

when i move a ocx control form my PC to a new computer, use "regsvr32 file.ocx", it show a error message of "loadlibrary("file.OCX")failure", but in my PC, it was working good not any failures.
can anyone help me to resolve this problem?
Thanks for you help.

Use Depends on the .ocx file to make sure that all of the dependencies are present on the target computer.
Why is common sense not common?

It seems all dependencies is right, look as follows:
ADVAPI32.DLL
COMCTL32.DLL
GDI32.DLL
GISQCONTROL.DLL
GISQSTYLEDIALOG.DLL
KERNEL32.DLL
MFC42D.DLL
MFCO42D.DLL
MSIMG32.DLL
MSVCRT.DLL
MSVCRTD.DLL
NTDLL.DLL
OLE32.DLL
OLEAUT32.DLL
RPCRT4.DLL
SECUR32.DLL
USER32.DLL
GISQCONTROL.DLL and GISQSTYLEDIALOG.DLL, it my compiled com dll. is there any another issues in this case.
|
|
|
|
|
Try profiling it through "dependency walker". Open "regsvr32.exe" in depends and select "Start Profiling..." from the "Profile" menu. Pass the path to the OCX in the "Program arguments" box and click "OK". See what DW reports in the messages box. You should get a clue or two.

HRESULT 8007000e corresponds to E_OUTOFMEMORY.
For Notes/Domino specific queries Lotus Notes forum[^] might be a good place to ask.

Hi, All!
I need to develop hook for income/outgoing email messages using MAPI hooks. How can doing that? Some links or samples will be very good

Hello,
perhaps somebody can help me to find the reason for the crashes I have.
I have a MFC Application with MFC extension DLLs.
One of the dialogs is a window with a CPropertySheet.
One CPropertyPage is a host for ActiveX Controls providing extending UI.
This CPropertyPage has a CWnd member to host the ActiveX Controls dynamically created runtime using the CWnd::CreateControl method.
I have a VB ActiveX Control providing needed extending UI.
It can be loaded and used without problems.
The only problem occurs, when the application exits:
1. The CPropertySheet is destroyed ... the CPropertyPage is destroyed, ...
... which releases its previously queried interfaces,
... sends a WM_DESTROY to the CWnd hosting the ActiveX Control and
... deletes/frees the CWnd
2. Somewhere at the end just before invoking "exit" open "OLE" connections/loaded "OLE" libraries are terminated by Microsoft internal code. I saw that the ActiveX OCX module was active until this moment.
3. In the "exit" invocation the MFC application crashes from within the VB ActiveX Control. The VB ActiveX Control does not execute its UserControl_Terminate handler, so it seems, that there happens an irregular deletion of the VB ActiveX Control.
This crash happens currently only in the debug version of our application. But adding CommonControls to the VB ActiveX Control UI causes a crash even in the release version of this MFC application.
Using a MFC ActiveX Control providing some UI, too, no problems occur.
The only difference seen while releasing the last reference to the previously queried interface are that ...
... the release on the interface of VB ActiveX Control returns 4 still valid references,
... while the release on the interface of the MFC ActiveX Control returns only 3 still valid references.
Thus I suspect, that at application end there is still a last reference valid, not released, which causes a crash after the OCX is unloaded from Microsoft internal code cleaning up before the real application exit.
Something in the VB ActiveX Control wants still to work (like executing UserControl_Terminate), but the OCX is already unloaded.
But ... where and how can I find this last reference?
Debugging through the MFC code hosting the ActiveX Control didn't help really?
Has somebody here experienced a similar problem? Or can somebody help?
Thanks in advance,
Martin

Hi Martin,
I think you are on right track. Just make sure you are not holding any reference in your own code. Use smart pointer (CComPtr, CComQIPtr). If you queried for an interface, make sure you release it in your OnDestroy. I don't think it matters that you are using an MFC extension DLL, as long you release your interface, it should work fine.
Did you try creating a separate project (simple dialogbox) using the activeX in question?

Hi Ernest,
thanks for your reply.
Until today morning I used no smart pointers, but using them does not change a thing.
I didn't expect a change in behaviour, because in my MFC C++ ActiveX control I could see, while debugging, that my reference handling was ok.
Ok - now I've introduced CComIQPtr and CComPtr, but it changes nothing.
The question is, why in comparison to the MFC ActiveX control one additional reference to the VB ActiveX control is hold!? And how/what is holding this reference to which interface?
The question raises, because releasing "my" interface I got a count of hold references of 3 with the MFC ActiveX control, but 4 with the VB ActiveX control.
And debugging through the deletion of my hosting CWnd I see only 3 releases on the interfaces of the MFC and the VB Active control.
So - where is the last reference on a interface to be found?
And ... do I have the possibility to change this behaviour?
Best regards,
Martin

Hello again,
first - I'm sorry, because I didn't provide any information about the development environment:
Microsoft Visual Studio 6.0 SP6
Microsoft Visual Basic 6.0 SP6
And ... no ... I can not upgrade - currently!
Second - I created a new most simple MFC application only loading the VB ActiveX control and raising an exception on exiting.
It has a CWnd* member on which CreateControl is called and which is deleted while deleting the dialog object.
So it shows the same behavior than the big MFC application I normally work on.
Has someone a hit or suggestion?
Best regards,
Martin

Hello,
after trying a bit I changed my VB ActiveX Control to execute the "UserControl_Terminate" things in the "UserControl_Hide" event handler.
Only the call "App.LogEvent ..." stayed in the "UserControl_Terminate" event handler.
And now everything seems to work fine.
Even a VB ActiveX Control with CommonControls (not even touched in the "UserControl_Terminate" event handler) works now.
So - I don't know why, but now everything works.
I found a solution, but no understanding for the problem.
Best regards,
Martin
