Composite Control and Slider EDGE - ATL / WTL / STL Discussion Boards

I was once asked to look at why a process was taking a long time to accomplish a task. One thing the process did was load a large number of entries into a CMap.

I did a bit of experimentation, and found that inserting 300,000 entries into a CMap took a bit over 4 hours. Doing 300,000 lookups on the CMap also took a bit over 4 hours.

I tried an STL map, and found that inserting 300,000 entries took 22 seconds, and looking up 300,000 entries took 19 seconds.

I've never had any use for CMaps. If you can, you might try switching to an STL map.

Wow! That's a huge difference! Nowadays I go for STL first with new MFC code. Not that I get to do much new MFC code these days. Though sometimes, depending on the context, the MFC stuff can be more convenient, e.g., CString.

How to map WM_CHAR messages for a modeless dialog

I have a modeless dialog with no Edit controls on it. The dialog is created by the WTL wizard. I would like to trap WM_CHAR messages at the dialog level. In the message map for the dialog I have added code like this:
MESSAGE_HANDLER(WM_KEYDOWN, OnKeyDown)
MESSAGE_HANDLER(WM_KEYUP, OnKeyUp)
MESSAGE_HANDLER(WM_CHAR, OnChar)
but no one of the methods gets called when pressing keys on the keyboard.
Any suggestion?

OLEDB question...

Sorry if it's wrong forum but there isn't one for OLEDB... Anyway. Is OLEDB simultaneous-multithread-access safe? Also ... using OLEDB - if different threads need to access the same database is it better to open that database from each thread or is it OK to use the same opened database object from different threads at the same time - reuse the connection?
Sorry for such a basic question. Blush | :O

AFAIK OLEDB is thread safe.

"LPSAFEARRAY" and "LPSAFEARRAY*" can be used only inside C++ sources, but not in IDL files. The valid IDL syntax for "LPSAFEARRAY" is SAFEARRAY(some_simple_type). For example:

[] HRESULT Test1([in] SAFEARRAY(BSTR) StringsNotApplicableForVB)<br />
[] HRESULT Test2([in] SAFEARRAY(BSTR) *Strings)<br />
[] HRESULT Test3([in,out] SAFEARRAY(BSTR) *Strings)<br />
[] HRESULT Test4([out,retval] SAFEARRAY(BSTR) *Strings)

In Visual basic, we can use TypeName to get the name of a COM object.
How can I do that in VC?
Some people told me that I should try ITypeInfo, but I can't find anything useful in it.

Turn on the Transparent style on the group box, that way it's painted after all sibling controls.

Add the .lib file to the linker command and #include any .h header files required.
