They can't see the records anyway - the view won't get populated. This is a database level permission. I already have the entire view non-responsive through my call to EnableWindow(FALSE) - from there, I just want a big visual cue that the view is not interactive, such as darkening the view.
Thanks

Well, you could always close the view, or create a separate view that simply contained the text, "You do not have permission..."

What does it mean to close a view? Replacing my view with another view would probably be very clunky with my existing design - I suspect I will have to do some drawing to the view.
I'd rather have something that is based on the view when permission is not denied, such as a darkened version of the same thing, or overlaying of a padlock icon. That way, the user may get familiar with the general layout of the program without necessarily being able to use it all.

Here's how far I've got:
void CCommonBaseView::OnDraw(CDC* pDC)
{
if(view_is_disabled)
{
pDC->SetDCPenColor(RGB(0,0,0));
pDC->SetROP2(R2_MERGEPEN);
}
CFormView::OnDraw(pDC);
}
It ought to be possible for me to change the way that we draw to the device context through the CDC pointer, and make the CView appear different somehow - darkening it, or making it grayscale, or something else. I don't seem to be having much luck drawing to the device context after the base class implementation has been called; It just makes swathes of gray turn white.
What approach is suggested?

Sternocera

Come on guys, I'd really like to get an answer to this! How can I draw onto a CScrollView from its OnDraw() to change its appearance significantly, such as making it grayscale or darkened?
Thanks,

Hi,
I have a multi threaded application which crashes at mfc42!CMapStringToString::GetAssocAt+14. Please see the DebugDiag tool output below.

I'm just wondering at the two MFC42 calls on top. These two are from two different classes. If my understanding is not wrong, it has to call GetNextAssicAt() method in CMapStringToPtr class but calling the method in CMapStringToString class. Could somebody help me here?
This application runs for few hours and processes thousands of messages and crashes randomly. Every time it crashes, points at same memory address.
Event description for crash: Faulting application DataConverter.exe version 1.0.0.0, faulting module mfc42.dll version 6.6.8063.0, fault address ox000234e4
Thanks in advance.

This sounds like a kind of race condition to me. Are you accessing this map from two separate threads ? If yes, make sure that you protect the map against concurrent access (with a critical section for instance). The problem might appear because two threads access the map at the same time, so the map is in an invalid state for one of the thread.

Hi Cédric Moonen,
Thank you for the response.
This Map is completely used by one thread but still I want to implement your suggestion and test it.
If you notice the MFC42.dll calls, there is something strange. I'm not understanding why CMapStringToString class's GetAssocAt() is called. It is supposed to call CMapStringToPtr class method.
thanks,
Mallik

HI All,
I have one ocx control developed in vc++/mfc and later the same code has been modified to use in automation server..now the problem is we need to keep separate clsid for the ocx control for server to avoid any conflict but its not changing the clsid even after changed in odl file..
Please show the right way to do this.
Thanks..

How do you know that (I'm assuming you've succesfully built the component with the new CLSID)?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Thanks..

Cannot you find the new CLSID in the registry?
Have you changed the interface name? Cannot you use the Oleview tool?

How do i insert a recordset where i take parameters from the user.
User enters his values in editboxes and when he hits "insert" button a query is fired
insert into table1 values (editboxvalue1, editboxvalue2 , editboxvalue3 , editboxvalue4 );
For this i can take values from editbox with the GetWindowText() method and store it in some variable .
but how should the query look like ,and should i use Connection::Execute() or Command::Execute() for this.
I have been using Connection::Execute( ) to Insert ,Update and Delete a recordset.
For queries with parameters which is a better choice ???
And how to form a insert query to insert values from user,into DB ???

Command::Execute, after appending a suitable number of parameters[^].

Could you help me with a link of this example where this insert is shown w/o using CADORecordBinding class.

Why - does Google not work for you? That's how I find these links.

Hi,
How can I load/insert an existing bitmap to the existing main application Toolbar? I do see where I can draw/Edit a new bitmap, but I have a bitmap that I downloaded from somewhere and I need to load that instead? How is this done usually?
Thanks

One way is to simply copy it over the existing toolbar.bmp file. If it's already sized correctly, you're good to go.

Thanks, I think I did that...I noticed the bitmap I am trying to copy has a different bit depth, like way off than the rest of the bitmaps for the toolbar...Would this be a reason to make it fail?

Fail as in none of the buttons work, or just looks funny?

No, as in my copy method is not doing the trick. I opened the toolbar in Resource Editor and tried to copy over the bitmap, but no success. Am I doing wrong?

Yes. Use Windows Explorer.

It isn't working...In Explorer, I browse to where the bmp(s) are, I have Toolbar.bmp and MyBitMap.bmp, I tried opening toolbar.bmp and copying Mybitmap over it, also, just tried drag and drop without opening...I must be missing something, becasue i wouldn't think it would copy the bmp file over another file (the Toolbar.bmp has the image of the tollbar bitmaps, but not editable obviously)...What do you think am doing wrong?
Thanks
