Hello all,
I feel a little bit stupid by asking this, but I've run out of ideas...
I'm trying to register and use an OCX control.
The steps that I'm following are this ones:
1. from a DOS window: regsvr32 ocxname.ocx
2. Once I receive the message saying that the control has been registered I start the Visual C++6.
A)
3. PROJECT -> ADD TO PROJECT -> COMPONENTS AND CONTROLS -> REGISTERED ACTIVEX CONTROLS -> ocxname.ocx.
Once I click on the just registered OCX control, I receive the message:
---------------------------
Microsoft Visual C++
---------------------------
C:\krc\LIB\Cross.ocx
Unable to open this ActiveX Control. Make sure the control contains a valid type library.
---------------------------
OK
---------------------------
B)
3. Right click on the dialog I want to use that OCX, select insert activex control (and select the just registered OCX control).
This inserts an icon of the OCX in the dialog, and if I go to the class wizard I can see that the control ID has been added, but I cannot add a new variable for that OCX, if I try to add a new variable for that OCX, I get this message:
---------------------------
Microsoft Visual C++
---------------------------
The ActiveX Control "KUKA-Cross-OCX" has not been inserted into the project. Developer Studio will do this now and generate a C++ wrapper class for it.
---------------------------
OK Cancel
---------------------------
When I select OK, then this message appears:
---------------------------
Microsoft Visual C++
---------------------------
The ActiveX Control is not registered properly, or its type library version number is incorrect.
Try registering the control by removing and importing it in the Component Gallery.
---------------------------
OK
---------------------------
I'm lost, I don't know why do that ActiveX control don't want to get registered properly on my system. And moreover I cannot get support information from the manufacturer...
Could you give me any idea on that?
As always, thank you in advance.

Seems to be something wrong with the typelib.
Open the ocx-file with OLE/VIEW to verify that it contains a typelib.
If it does, have a look in the registry at the following:
Locate the ProgID of the ActiveX below HKCR to get hold of the CLSID.
Locate the CLSID below HKCR\CLSID. Below that key there should be a 'TypeLib' key with the GUID for the typelib as default value.
Locate that GUID below the HKCR\TypeLib path. Below it you should have at least one key that corresponds to the typelib version of the control. Below that key you should have at least one key that corresponds to the language used by the control, the LANGID where zero means "language neutral" and is usually the only one present. Below that key you should find a 'win32' key where the default value is the path to the file that contains the actual typelib, usually the ocx-file.
Verify that the file is present at the designated location. You could correct it if it's erroneous.
If the information above doesn't exist, try and deregister the control with "regsvr32 /u ocxname.ocx" and verify that all keys are deleted.
Register it again and verify that the keys are written.

Wow Roger!
That has been a complete answer!
Well I've tried that, I've opened the OLE Viewer and then I selected the first option in the menu in which you can view the type library. Then I've selected the ocxname.ocx control.
Once I've done that a messagebox appeared a couple of times telling me:
---------------------------
OLEViewer 2.0 Interface Viewers
---------------------------
Could not decompile selected item
<no system="" message="" defined=""> TYPE_E_CANTLOADLIBRARY ($80029C4A)
---------------------------
OK
---------------------------
Do you know if this is a problem? and if it is one, do you know if it has any solution?
Thank you in advance for your time and help.

It looks to me as if the ocx-file doesn't contain a typelib, or the file is corrupt.
Did you by any chance get other files with this ocx-file, like *.tlb or *.olb files?
If you didn't, it means that you don't have the typelib for the ActiveX control and you probably should contact the support department of the supplier.

I've found a .tlb file but it has not the same name of the ocx control.
Do you think that this can be a problem?
Can I import a TLB file?
Thank you in advance!

Open it with OLE/VIEW and have a look.
See if it could be the typelib for the ActiveX control.
What does it say? What's the name of it?
Is the ActiveX control part of a larger package?
Joan Murt wrote: Can I import a TLB file?
Absolutely.
But you'd better select the right one. 
If you f.ex. choose to run office application through automation, you #import .tlb and .olb files.

I have a program that graphs data from a device on the fly. To update the graph every second I call the InvalidateRect function. When the program runs for a while (e.g 1 hour) it's fine, but when I run it over night and come back in the morning to check it, the whole computer monitor is white. I then minimize my program (when I scroll over the buttons on the taskbar they start to appear) and everything is back to normal. It seems the InvalidateRect function messes up my refresh rate or it some how invalidates the whole screen even though i specified a small rect on the window. Anyone know how I can solve this?

Do you have a screen saver? ( even a screen blank) It can cause some refresh problem also.
Are you certain you do not have resource leaks or memory leaks ?

This may be a tall order.
Looking for a VC++ 6.0 MFC IDE template.
Something similar to Altium DXP.
I guess a combination of split view - with tree control in left pane ( inside tab control would be nice) and a tab control in right pane.
There are plenty of piece parts in CodeProject, but I have not seen a complete IDE application here.
Thanks for reading.

Use AppWizard to create your basic SDI application. In the CFrameWnd-derived class, add a CSplitterWnd member. In the frame's OnCreateClient() method, do something like:
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
m_wndSplitter.CreateStatic(this, 1, 2);
m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CLeftPaneView), CSize(70, 0), pContext);
m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CRightPaneView), CSize(0, 0), pContext);
return CFrameWnd::OnCreateClient(lpcs, pContext);
}You'll then need to use ClassWizard to create two views, one for the left pane and one for the right pane.

In a simple way, you cannot do it with CMenu as you'd do with CWnds. Instead, you should have custom drawn menu to define the way it is painting its items.

I recive an error in line with message map:

Error is:

Pointers to members have different representations; cannot cast between them
ok, i see i have different parameters, but how to do right!

Are you using VS6 or VS200x?

Hello David,
i use VS6.

Read the error message. The compiler is expecting the parameter list to be (NMHDR*, LRESULT*) but your function has (WPARAM, LPARAM, LRESULT*) (mentally substitute LRESULT for long, it's a typedef)
