I have a MDI Project
With a MainFrm (1)
There i open Child-Windows of type CMDIChildWnd (2)
A View of element as type CFormView (3)
And the content of the View is a Dialog (made with the Ressource Designer) (4)
If i start the applic and hit a key on the ChildWindow. Which element does get the OnKeyDown Event?
2 & 3 does it not get.
It's logic that the "highest" Element receive the message -> 4: The Dialog
But i "linked" myself the Dialog to the CFormView ...
I saw that it's possible to create directly the CFormView from out the Designer with "Add Class"
Now i don't have a reaction if i hit a key on the Childform
Is it absolute necessairy to create the CFormView with the Designer?
In my CFormView i have
afx_msg void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags);<br />
<br />
BEGIN_MESSAGE_MAP(TheViewClass, CFormView)<br />
. <br />
.<br />
.<br />
ON_WM_KEYDOWN()<br />
END_MESSAGE_MAP()<br />
<br />
void TheViewClass::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)<br />
{<br />
CFormView::OnKeyDown(nChar, nRepCnt, nFlags);
}
Is it the right procedure to make ChildForms ?
Big thanks

The event goes to the elemenet that has the focus.
Check differences between onchar and onkeydown events....
|
|
|
|

Ok i see, that seems logic
So i need to have in each class, that has the focus, a Message-Handler for KeyDown with the corresponding afx_msg On_KeyDown
If i want catch a KeyDown on an CEdit Textbox, i need to derive a class from CEdit that
has a OnKeyDown ...
correct? 
Can i say this->getParent()->getParent() to access the MainForm ?
Many thanks ! 
All these questions aren't in MFC Books, so it's hard to find a resolution by myself

Normal Dlls are language dependent or Not ?
can we use C dll in C++ and viceversa ?
I read that Com Dlls Are Language independent And Normal Dlls Are Not.
Is it True ?
|
|
|
|

COM are just a specific kind of dll's that follow some rules so that they can be used in different languages. So in brief, if you take some special considerations, your C dll can be used in C++, VB and other languages.

With Out Following COM specifications Can i use My C Dll in C++ or VB ?
|
|
|
|

Yes but you have to take care about calling conventions for example (and don't know exactly everything that you need to take care of). Simply search on google and you'll find quite a lot of article

I think Again you are saying about COM Dll in the Above Context.

As usual, I checked LNK 2019 , in MSDN Apr-2001. And could not find it. With VS 6.0 its LNK 2001. Thats why asked for error message.
Though, its present in latest one. I should have checked that.

Did you see Requirements on MSDN?
Header: Declared in Psapi.h.
Library: Use Psapi.lib.

Hello friends

Remark from MSDN about Execute:
Execute works only for action queries or SQL pass-through queries that do not return results. It does not work for select queries, which return records.
|

One way is to derive a class from CDaoRecordset. Then just change the GetSQL() method (it default to SELECT *) to select those columns and rows you want.
