This is just the handle to your application's main window (whether app, or dialog). Windows needs it to discover who makes the call to an API function. You don't need to figure out how to use it so much as use the value that is returned by a CreateWindow() call, or in a Dialog application the handle that Windows sends you on every callback.

Sorry but still stuck, I'm pretty much a n00b programmer.
By using it I mean I just have no clue on handles or what not or where to put m_hWnd, it comes up as undeclared identifier. Everytime I've coded I've never really bothered with this and if some piece of code included it i just stuck it in and hoped it worked.
I have no CreateWindow call and I have no idea where in my program (which isn't really my program) windows sends a handle.

I would suggest that you get hold of a book on Windows programming to get an understanding of the basics; Charles Petzold has written some very good ones.

Hi,
I am wondering if any of the experts can give me some insights into the Different behavior
of the RichEdit when the object is Connected
By DDX_CONTROL as opposed to Create
1) The Font is Different
2) GetTextExtent for calculating the Length
of a line works differently (maybe
this has to do with font)
3) The Background Color is different
with DDX_CONTROL it seems be in
reverse video (when I right
it goes away)
thankx

I can't answer 100%, but I'll help a bit.
The difference is not DDX_Control. That just helps you associate a variable in your dialog with a window.
The difference is:
a) A control "built" in to the dialog resource, and created automatically as part of the dialog creation,
and
b) A control you create manually, later.
So, to answer your points...
1) Different Fonts.
At creation time for the dialog, it sets the font (WM_SETFONT) of the child windows (ie, your rich edit) to the same font as the dialog is set to use.
When you create a window manually later, this step does not happen.
2) Different extent sizes.
Almost certainly the same issue. Text size comes from fonts.
3) Inverse background colour.
Not sure, but I bet the text is inially selected, or something along those lines. Try dragging the mouse over text - I bet it goes inverse too.
Points 1 & 2 would be the same for a button, or an edit control... Nothing to do with the rich edit control at all.
Hope that helps!
Iain.

I guess I can send EM_GETCHARFORMAT to the rich edit control after the DDX_CONTROL connects it to the object
and find out the font
I can then set it with the EM_SETCHARFORMAT message
|
|
|
|
|
Think you right I Sent EM_GETCHARFORMAT message to get the Font
With Create there was garbage in the szFaceName
With DDX_CONTROL It was "Shell Dlg 2"
Tried to change the font with EM_SETCHARFORMAT setting CFM_FACE and CFM_SIZE
that didn't seem to work
Anyway thankx for your help

Hi
in my project i import msado15.dll to opetate data from database
now i want to let the data can print in ms-word,so i
#import "C:\Program Files\Common Files\Microsoft Shared\OFFICE11\MSO.dll" rename_namespace("AAA")
but it said:
error C2011: '_Application' : 'class' type redefinition
error C2011: '_Global' : 'class' type redefinition
error C2011: 'FontNames' : 'class' type redefinition
error C2011: 'Languages' : 'class' type redefinition
error C2011: 'Language' : 'class' type redefinition
error C2011: 'Documents' : 'class' type redefinition
error C2011: '_Document' : 'class' type redefinition
..........................
i know it should rename_namespace, but i am a fresh man, i can not find example
how can i work this problem, how to rename namespace, and what name should be renamed
thanks a lot
Sincerely

Are you using the same namespace name in both #imports?
If both DLLs contain the _Application object you will get this error.
So try this -
#import msado15.dll rename_namespace("AAA")
#import mso.dll rename_namespace("BBB")
Now you can access the ADO object as AAA::_Application and the Office object as BBB::_Application.
|
|
|
|
|
can i use
#import msado15.dll no_namespace
#import mso.dll rename_namespace("BBB")
because if msado15 renamed,my project many code should be modified,because msado's method i have used
thanks a lot
|
|
|
|
|
Sure.
Now you can access MSADO15's class as just _Application and MSO's class as BBB::_Application.
|

Have you tried something like:
#import <mso.dll> rename("_Application","_MSOApplication")Although Superman's suggestion is a bit cleaner.

Dear,
how to get and print dial-in tab properties of user object in active directory using c++
|
|
|
|
|
I've some dialogs that I use as child dialogs in a FormView driving them with a TabControl.
My problem is that when dialogs are shown, they doesn't catch events like mouse click, so that
the user cannot handle any control inside the window.
If I switch the windows property from Child to Popup any control works properly but the windows are
not shown correctly within the TabControl.
So.. how can I let all events work fine for child dialogs ?
|
|
|
|
|
My only thought is that the windows are visible, but disabled.
Use Spy++, and check the WS_VISIBLE / WS_DISABLED for the windows involved.
Iain.

I have a static class I use for caching data. This will now be accessed from multiple threads which means I need to add a CRITICAL_SECTION to make updating the cache thread safe. I now have the problem of who initialises the CRITICAL_SECTION given a static class doesn't have a constructor.
std::map<int,std::string> CMY_CACHE::m_cache_map;
CRITICAL_SECTION CMY_CACHE::m_critical_section;
class CMY_CACHE
{
private:
static std::map<int,std::string> m_cache_map;
static CRITICAL_SECTION m_critical_section;
public:
std::string read(int index)
{
EnterCriticalSection(&m_critical_section);
std::map<int,std::string>::iterator it=m_cache_map.find(index);
if (it==m_cache_map.end())
{
}
LeaveCriticalSection(&m_critical_section);
return(it->second);
}
...
std::string s=CMY_CACHE::read(0);

Instead of having all members static, you could use a singleton pattern: it is a design pattern that makes sure your class is created only once. I won't go into much details here but I suggest you google for "Thread safe singleton pattern". Basically, you add a public static function that returns a pointer to your single instance (CMY_CACHE* CMY_CACHE::instance for example).
Once your class is a singleton, you can simply create your critical section in the class constructor. Your read method is no more a static function and you call it this way:
CMY_CACHE::instance()->read(0);
|
|
|
|
|
The quick & dirty (you're warned...) trick: wrap the CRITICAL_SECTION in a struct and do initialization (cleanup) in struct constructor (destructor).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

... or, instead of a singleton, you could write a CRITICAL_SECTION wrapper class.
e.g. something like
class CS : public CRITICAL_SECTION
{
public:
CS( ulong SPINCOUNT = 4000 ) {
#ifdef _DEBUG
::InitializeCriticalSectionEx(this, SPINCOUNT, 0);
#else
::InitializeCriticalSectionEx(this, SPINCOUNT, CRITICAL_SECTION_NO_DEBUG_INFO);
#endif
}
~CS() {
::DeleteCriticalSection(this);
}
};
then use it wherever you used CRITICAL_SECTION.
...cmk
The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.
