Hi,
suppose there are to struct type,
struct small
{
float x;
double y;
};
struct large
{
int x;
float y;
double z;
bool w;
};
and in my program I coding as this:
large b;
small *p =(small) b;
what's going on inside the code operation?
Thank you.
Best regard.
I confess that I am a stubborn guy, but why not put things thoroughly, logically and systematically clean. One concrete prolem is worth a thousand unapplied abstractions.

This won't even compile. You are attempting to assign small to small*,( via unsafe casting).

how do you add libs to a project in msvc? do you add the file itself to the project or include the name of said lib in the list of included libs in the project settings.
|

You can do it either way, but I prefer to do it in the project settings.

Sometimes (always) I'm lazy...
so I add libs via include file, here an snip from my OpenGL project:
<br />
#pragma comment(lib, "OpenGL32.lib") //link with OpenGL32 Library (VC6 Sytnax)<br />
#pragma comment(lib, "Glu32.lib") //link with Glu32 Library<br />
Hoep it helps, Moak

I'm learning to use DialogBoxes in "C", via LCC-win32 compiler. My question is about managing virtual-keys. I can manage them while dialogues don't have controls (via WM_KEYDOWN message) but otherwise can not capture these virtual-keys. I guess this is about focusing on child-windows(buttons, checkboxes etc). But why? How?... In fact I can manage them if I use "ACCELERATOR" but want to learn that if is there a solution to do this without accelerator tables. I can not give a meaning to this. Isn't this WM_KEYDOWN message sending before a control? For instance, I have an aboutbox which has two buttons(OK-CANCEL), how can I capture VK_END virtual-key?(again; without accelerator tables). Thanks from now on whose interested in.

Maybe you could try handeling the pretranslate message and trap it there. Not sure, just a guess.

In dialog boxes, handling accelerator keys require a slight tweak. I have explained this in the following article :-

Hi,
Thanks Nish. Thanks for your advance. In fact I'm very weak in C++, nevertheless I will try your article
|
|
|
|
|
Anyone have some info on that? I'd very much like to learn something about it. The new Winamp 3 has it, anyone know anything about it?
Thankyou

I don't remember the names of the functions you use to make transparent windows, but search in the articles, I know there's a couple about this subject...

They are supported only in W2000 and XP AFAIK. So to write an app that uses them you need to late bind to the function and detect the OS before callng them. I've done it, LMK if you can't find an article that covers this stuff and I'll knock one up for you.

You should be able to find a couple of articles in MSDN and the APIs if you do a search on Layered Windows.

Actually it's not that hard, you just use the SetLayeredWindowAttributes function.

WHen i try to compile my program, the compiler says that WS_EX_LAYERED and LWA_ALPHA an undeclared identifier. in the msdn library it says to include the windows.h file, and i have already included that...
|
|
|
|

You need a later platform SDK in order for these to be defined.
If you don't want to bother downloading it, slap this on your source file:
#ifndef WS_EX_LAYERED
#define WS_EX_LAYERED 0x00080000
#define LWA_COLORKEY 0x00000001
#define LWA_ALPHA 0x00000002
#endif

I am trying to implement a document/view application. I got the program to compile but it stalls when the line 'AddDocTemplate(pDocTemp);' is executed. I keep getting the 'Debug Assertion Failed' box. Below is a snippet of the InitInstance code. Thx
BOOL CApp::InitInstance(void) {
//register class and document
CSingleDocTemplate *pDocTemp;
pDocTemp = new CSingleDocTemplate(IDR_APP,//UINT nIDResource
RUNTIME_CLASS(CAppDoc),//CRuntimeClass* pDocClass
RUNTIME_CLASS(CMain),//CRuntimeClass* pFrameClass
RUNTIME_CLASS(CAppView));//CRuntimeClass* pViewClass
AddDocTemplate(pDocTemp);// !!!Problem here
//parse command line info
CCommandLineInfo cmd;
ParseCommandLine(cmd);
//dispatch command line info
if (!ProcessShellCommand(cmd))
return FALSE;
//show/update window
m_pMainWnd->ShowWindow(SW_SHOW);
m_pMainWnd->UpdateWindow();
return TRUE;
}

Hi,
Does anyone know of a good FREE platform independant source
code control system that works with Visual C++?
I tried installing cygwin and its port of CVS
but Visual C++ projects seem to have a problem
co-existing with it. 
Thanks
|

I haven't used it myself but you might want to give WinCVS a try.
Good luck!

Folks,
When I replace the background HBRUSH on a Window:
1) Am I expected to delete the OLD HBRUSH?
2) Expected to delete my NEW HBRUSH?
Or both? 
Mike.

Restore the old one when done. Then, you can call DeleteObject() on both.
