Disable your top level window in the OnCreate of your "modal" frame, and re-enble it in the OnDestroy.

missing resource folder? nafxcwd?

2 questions about VC++:

first, when I close VC++ and then reopen an MFC project in VC++, my resources file is gone...where did it go. I clicked on the .dsw to open my workspace but the resource folder doesn't even show up.

second, I get the following message in my debug window:
"fatal error LNK1104: cannot open file "nafxcwd.lib""
It appears that my library is not linked properly, no? How do I remedy this problem?

tanks much, Dave

OleCreateFromFile and OleCreatePictureIndirect

Hi,

I use OleCreateFromFile to create some ole bitmaps at the start of my program. This bitmaps are embeded in some richeditctrl's. The problem is the more bitmaps I have, the longer it takes for my program to load (because it reads the files from the disc).

I want to use OleCreatePictureIndirect which creates ole's from HBITMAPS that I can build from my resource bitmaps, reducing in this way the loading time. But I dont seem to get this function in vc7.0. Can you help me with this, please?

Thanks

headers/functions

I have run into the problem of not knowing which headers files I need to declare with functions I want to use. Is there a way in VC++ to determine which header goes with which function? Also, I would like to know what the hundreds of different standard windows functions do, is there a book or a website that could help me learn?

Thanks

If you know function name and want it's header file, simply press F1 (help) when you are on function!
MSDN will show you detail of function and it's header file and library.

Call GetSystemMetrics() with SM_CXMENUSIZE and SM_CYMENUSIZE to get the width and height of these items. You can compute their position from the window's dimensions. You'll need to use SM_CXBORDER and SM_CYBORDER (i.e. passed as args to GetSystemMetrics()) in your calculations.

i feel boring that in XP, the width and height of SM_CXMENUSIZE && SM_CYMENUSIZE is 18, but obviously the maximizebox and minimizebox are larger.

Here are some values got from GetSystemMetrics:

2000 ____________ XP
SM_CXICON 32 ____________ 32
SM_CYICON 32 ____________ 32
SM_CYMENUSIZE 18 ____________ 18
SM_CXSIZE 18 ____________ 25
SM_CYSIZE 18 ____________ 25
SM_CXSMICON 16 ____________ 16
SM_CXSMSIZE 12 ____________ 27
SM_CYCAPTION 19 ____________ 26
SM_CYSMCAPTION 16 ____________ 18

Any way to keep console.exe open?

I've tried several ideas and so far nothing seems to work. I'm simply trying to add some code to keep a console 32 program open. This is the release version of the program being opened from Windows Explorer. I've tried _getch(); and even a while(!getch());

ANy ideas? Cool | :cool:

_getch() always worked for me. You must be doing something wrong. Posting some code that "doesn't work" would help. (is my depth of perception increasing?)

getch() usually does the trick. however, if there are any keys in the queue, it will see them, so you should use

while (kbhit()) getch(); // empty keyboard buffer
getch();

One important question: What happens when you are in the debugger? Does it make it to the _getch() statement?

Well, I am not the one having troubles with a getch() statement, that even the kids in my neighborhood know how to use it by now. You have posted this question so many times that one would think that you are dealing with the problem of the century. Read some books first.

use a macro like
#define max(a, b) (a > b ? a : b)
or if you need a variable ammount of arguments, create a function that uses va_list, like this one (MSDN example)

Re: Maximum function

peterchen28-Jun-03 14:29

peterchen

28-Jun-03 14:29

just two notes
a) you shouldn't use a macro if it can be expressed in the language - i.e.
template <typename T> inline T max(T a, T b) { return (a > b) ? a : b; } should do it without side effect problems, correct name scoping
b) if you need to use a macro, use braces around each argument,
#define max(a,b) ((a) > (b) ? (a) : (b))
