You've got a semi-colon at the end of #define PLUGIN_API __declspec(dllexport)<span style="font-weight: bold;">;</span> - you don't want that.
Also - you don't need to use PLUGIN_API in the cpp file - doesn't hurt, but it's not required.

Hello Stuart,
Thanx for catching that semicolon.
All compile and run ok.
In DoubleIt() I have added a call to the motion control EXE program for which the plugin is written and by which the plugin has been loaded. This new DoubleIt() works ok when called from elsewhere within the plugin but not when it is called from the vision control EXE program.
When the plugin function is called from the vision control EXE I get the message "The instruction at "0x0000000" referenced memory at "0x00000000". The memory could not be read."
This only occurs if the called plugin function is trying to call a function in its parent EXE. BTW, I get that same error message if the DLL is not loaded at all.
I think that the called plugin function is not exactly the same as the one that is loaded with the DLL. I am guessing that all the pointers must be found in memory as needed.
How do I setup the compiler options so that the vision control EXE program can call the motion control EXE program via the motion control's DLL plugin. Or perhaps directly from the vision control EXE to the motion control EXE since the motion control EXE program must have used dllexport so that the plugin can call motion control functions.

Nothing to do with compiler options, I suspect. I guess the plugin is expecting the executable that loads it to provide certain capabilities - there must be some defined mechanism by which it knows the addresses of the functions in the EXE.
Tom Hubin wrote: motion control EXE program must have used dllexport so that the plugin can call motion control functions
Not necessarily - there might be some other mechanism by which the plugin can get function addresses.
I feel you're on your own, I'm afraid - if there's a specification for the plugin interface, that might define how you get the exe function addresses?

Create a named event in the plugin and wait on that event to become set.
When the event becomes set, call the required function.
From the camera program set the event when needed.
You may want to look at CreateEvent and SetEvent.

You can modify the header text .. Does it make sense??

The way it's done in the sorted list view control in the WTL library[^] is to use the hbm member of the HDITEM[^] attribute of the header of the sorted column to set an up arrow or down arrow bitmap for the header. If you tell the bitmap to be to the right of the header's text, you'll get the effect you're wanting.
The bitmaps are available in shell32.dll as image resources 133 and 134.
You can learn a lot about this by looking at the implementation of CSortListViewImpl in the file atlctrlx.h in WTL...
The SetSortColumn method of this class shows how to set the bitmaps correctly, while the CreateSortBitmaps method shows how to create the bitmaps.

Invalidate does not work for me. Any other way?

You should ask Microsoft for a custom Invalidate, working for you.

i dont know what his problem is, but i have similar issue with InvalidateRect when when i was creating a control in win32, i tried RedrawWindow also but not worked. I solved issue by using the following code.
HWND hParent = GetParent( hChildControl ) ;
InvalidateRect( hParent , &rChildRect , TRUE ) ;

What kind of child was that? I mean was it a static control? What was its class styles?

Your site is better I think it has a function Invalidatemyrequest(very urgent);

You must be using this API on wrong object. There is no way Microsoft has put some switch condition, not to work on your machine.

Did you use like this?
Invalidate();
UpdateWindow();

Hello all,
I created a window. Over that window i created some controls of the class CButton, CEdit,CStatic, CComboBox.
My problem is that, i have to assign the tab order for this controls. I set the WS_TABSTOP property while creating this controls. But tab order is not set for this controls. How can i set tab order for this controls.
********************
CEdit* pedtName = new CEdit();
pedtName->Create(ES_MULTILINE | WS_CHILD | WS_VISIBLE | WS_TABSTOP,CRect(160,140,300,170) ,this,EDITNAME);
|
|
|
|
|
use
pedtName->SetWindowPos(...)
see the first parameter of SetWindowsPos
|
|
|
|
|
Sorry sir, it doesn't work.
I created two edit control as follows on the OnCreate() method of the application.
**************
CEdit* pedtName = new CEdit();
pedtName->Create(ES_AUTOVSCROLL | ES_AUTOHSCROLL | ES_MULTILINE | WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER,CRect(160,100,300,130) ,this,EDITNAME);
pedtName->SetFont(pFont,TRUE);
CEdit* pedtSurName = new CEdit();
pedtSurName->Create(ES_AUTOVSCROLL | ES_AUTOHSCROLL |ES_MULTILINE | WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER,CRect(160,140,300,170) ,this,EDITSURNAME);
*****************
When i run the application, focus will automatically set to pedtName control. When i press tab key, tab focus will set on pedtSurName.
But now it doesn't work. How to do this?

As other reply says you can use SetWindowPos for altering tab order.
You can also check here[^]..
I hope it helps.

Sandip.

Why don't you simply create the controls in the order that you want.

If you want to set Tab Order on the dialog forum you must be press Ctrl+D or runtime liek this:
CWnd *m_pWnd1 = GetDlgItem (IDC_BUTTON1);
CWnd *m_pWnd2 = GetDlgItem (IDC_EDIT2);
m_pWnd1->SetWindowPos (m_pWnd2, 0,0,0,0, SWP_NOMOVE | SWPNOSIZE);

I had a old application developed in VC++6.0, with intraction with SAP RFC
and Iona Orbix(CORBA), Now we are migrating to VS 2005., and at this moment we are wondering to replace corba with now latest technilogy(ie.NET/ or ..), which out make chages in the much of the code.
Please advice efficient posibe ways and the respective adventage/disadvantages.
Thanks in advance.

You can have a look at ICE. Here[^] is a comparison between ICE and Corba. I never used ICE myself so I can't say anything about it, but I think it's worth a look.
