Perhaps, I found out the right answer, form the C99 standard, about compound ass.:
Semantics
3 A compound assignment of the form E1 op= E2 differs from the simple assignment expression E1 = E1 op (E2) only in that the lvalue E1 is evaluated only once.
So E1 is evaluated ONCE
|

No that isn't what that means.
E1 appears on both side of the equals. It is referring to whether E1 is evaluated once for the lvalue side and once for the rvalue side. And it says no.

Dear all:
I want to implement a application, when I touch the pannel, the application will play sound globally.
I use hook(WH_MOUSE_LL) and WM_LBUTTONDOWN to process the touch and PlaySound to play wav.
The Question is :
when I touch the pannel, it does not play. if I touch and leave fast, it will play.
How do I solve this problem?
Thank for your help .Victor

Dear Randor:
My application function must be have:
1.When I touch anywhere, even not on my app(ex:desktop, other application, extc...), it will play sound.
so I must be use hook, I did not find anything about hook with touch.
Does anything else to implement this application
Thank for your help, Victor

Microsoft recommends that you use a HID filter driver for something like this. You might be able to hack something together with a WH_GETMESSAGE hook.
I will now go and answer your original question.

When you use the touch screen and 'HOLD down' the touch driver may interpret this as a right click. If the application did not register itself as being 'compatible with touch' a WM_RBUTTONDOWN followed by a WM_RBUTTONUP would be injected into the input stream.

Dear Randor:
I think you are right. It is different between touch and mouse.
when left mouse button down, it will play sound.
when I touch the panel, and leave fast, it will play or touch the panel, and then move my finger on panel, it will play sound, too.
Thank for your help, Victor.

This is puzzling me.
I can add menu item with system generated and #define(d) ID and the menu text will be grayed out until I add a function to process the ON_COMMAND macro.
However, I have a static DLL which has just the #define(s) IDs and if I use the ID in MFC
OnCommand function ( WPARAM) – in case switch – the menu will be active.
The way it looks – if the ID is defined in DLL the menu is OK, but if “locally” it needs the function in ON_COMMAND macro and than the OnCommand function is not used.
If this is normal , OK
Thanks for your time.
Cheers
Vaclav

That's a static dynamic link library.

Ok, nice catch and just for you - "Win32 Static Libray".
Now back to OP.

No, it's for everyone, because there are important and fundamental differences in how a static library and a DLL are connected to the executable. And that affects how your problem occurs and how it may be resolved.

LIB + DLL + .H . I think you should add you Dll,lib and .H in you Debug folder . Then you can use it just like a class. you can try !

You just posted that to Richard...

Stick to the point Richard.

What? The point is that much of the question makes no sense.
|
|

|

Not sure I follow what you're saying... elaborate a bit perhaps?

It cant be defined in a dll, it must be defined in a header file to have any meaning in your app.
Don't really get what you mean though.

Hi,
This is completely normal in MFC from a CFrameWnd derived class. This behavior is governed by the variable CFrameWnd::m_bAutoMenuEnable[^].

Thanks David.
I will try to clean up my code - it seems silly to intercept the menu message using ON_COMMAND macro and "re post" same message so OnCommand can process it.
It really does not matter, to me, where the menu message gets processed, but since I started using libraries / modules I was just rying to keep processing uniform and under one function.
It was dissapointing that majority of replies managed to stay off the subject.
Cheers Vaclav

It was disappointing that your original question was so confusing.

Dear all:
I wanna implemented a app with only one button.
Function of application:
1.The Application with a button, that we can select sound by button.
2. When touch the panel, it will play sound, not only on my app(ex: desktop).
Question:
1.How do I use hook with touch event? Does anything else to implement this application?
2.if I use hook, how do I set the sound path in hook, when I select?
I am a new one of MFC, and my english is not good, please forgive me.
Thanks for your help, Victor.

If this is not the proper place for this question, please let me know where I can post it.
I am working on a bunch of MSBuild project files that were created from scratch. We are in the middle of upgrading to Visual Studios 2013 so a lot of the paths to libraries need to be changed. I am having trouble with the Microsoft Libraries because of the spaces that are in the path.
Here is the line that sets the base of the path to get appended later in the project file:
<CRT_LIB_PATH>C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\lib</CRT_LIB_PATH>
Later there are lines similar to the following:
<LINK_LIBS>$(LINK_LIBS) '"$(CRT_LIB_PATH)\msvcrt$(DEBUG_SUFFIX).lib"'</LINK_LIBS>
In the second line, I have attempted single quotes, double quotes, single quotes surrounded by double quotes, double quotes surrounded by single quotes. Nothing had helped.
How to I properly put this path into the project file?
Thanks,
Kevin
What happens is everything before the "12.0" is lost and linker is not able to find the library.
