Hi, I am not good at programming. So, I hope somebody can help me to solve my problem. I already think it for a long time.
My question is I have 2 set of datas. They are stored in variable no[i] and result[i].
no[0]=0.12 result[0]=medium
no[1]=0.27 result[1]=medium
no[2]=0.67 result[2]=short
no[3]=0.43 result[3]=medium
no[4]=0.98 result[4]=high
no[i] and result[i] will combined together( i.e. 0.12 medium, 0.27 medium....)
And my expected result is "0.12medium, 0.67 short and 0.98 high."
How can I program it such that the computer know there have a three type of data, medium, short and high respectively.
The question is so long!!!
Thank you very much!!!

I would declare an enumeration in one of your header files that the "result" set can see the enumeration like this:
enum {short = 1, medium = 2, long = 3};
Then you can use that code in your array. When you need to make your combined string or output, you will just need to decode a 1 to mean "short", 2 for "medium" and 3 for "high".
Good Luck

As has been said, an enum is the obvious answer. The other thing is that if your two values are really one complex type, declare it as such with a struct.
enum Result {short, medium, long}; // can use short = 0, medium =1, etc. with whatever values you want, but unless you use the values directly, it does not really matter what they are and they should be 0, 1, 2 by default.
struct myType
{
float no;
Result result;
}

In an MDI application ( well, not really, it's an MDI with only 1 "view" definition )
On my mouse move, I need to hilight items in the view, so I can either draw in the ON_WM_MOUSEMOVE ( in the CView derived class ), or mark item to be drawn, and wait till an Invalidate (WM_PAINT to trigger the OnDraw of the view )comes in to draw it ?
Now, if I want to highlight the item in all the views (frames ? ), with the first option, I'd have to call the Document UpdateAllViews( this ) ( this is the current view ) ?
Ok, I think I get it, the UpdateAllViews call an update on the DIFFERENT views, not the same VIEW in different FRAMES ... Is there a better way to loop true the different "frames" than with a loop on CWnd and check for CWnd::GetWindow(GW_CHILD) ?
and I had a check somewhere that checked only the active view !
And now it's working ... I started writting this 2 hours ago ...
Max.

That's an MDI app. The "MD" refers to multiple open documents, not multiple *types* of documents.
Imho, you should do as little work in a WM_MOUSEMOVE handler, so I think you're doing the "right" thing.

A simple question, but one I wasn't sure about. Why do you sometimes need lib files along with dlls for everything to work?
|
|
|
|
|
the .lib file that comes with a DLL is allows you to call functions in the DLL as if they were functions in a static library (the .lib). without this .lib, you would have to do GetProcAddress a call for each function in the DLL - no fun.
-c
A conclusion is simply the place where someone got tired of thinking.
|
|
|
|
|
The lib files contains information that the linker (almost like the compiler) needs to know what functions, and where, are in the dll.
The reason why you sometimes need the lib files, is that the linker often finds them automatically.

As it is well known, CStdioFile doesn't support functionality to read text files in neither Unicode, nor UTF-8 formats.
Does anybody know something similar to CStdioFile with function ReadString, that is support Unicode?
Thanks in advance!

Build .Net app, and take it to a non .NET box. Receive error DLL MFC70.d;ll could not be found. Is there a way to build in release mode so that it will have whatever files it needs no matter what box I take this program to? I want to avoid using an installation program.

If it's a .NET app then you'll need the .NET runtimes installed on the target machine

In the project settings, under general, you can select to use MFC in a static dll, then it's included in your program...

How can I check if a popup menu closed?
When I click with the right mouse button on my view I show a popup menu and mark something on the view (draw a rect where I clicked).
So, I want to know when the popup window is closed (switched off the screen) to redraw my view, so that my mark will be cleaned!
Is there any message the popup window send to the parent?

You could just send a message of your own before the window closes

I want my application to have maximized mdi childs and normal (or restored) mdi childs at the same time. Like seen in the Opera web browser.
Any ideas where I can start looking?
|
|
|
|
|
I can't comment on Opera, but with MDI this isn't possible. When one MDI Child is maximized they all are and vice-versa. My guess is that Opera isn't using MDI. You can check with Spy++ or Russ's WinSpector++ here on CP.

I have the following problem trying to pass a class as a parameter in a template function:
I am using a function like this:
pMainFrame->PlugNewModule(RobCtrlPage::IDD,RUNTIME_CLASS(RobCtrlPage));
the function looks like:
PlugNewModule(UINT nID, CRuntimeClass* pRTC)
{
UINT ID = nID;
CRuntimeClass* _pRTC = pRTC;
...
}
the question is, IDD belongs to RobCtrlPage, if we pass the class as a parameter we make the function easier. SOmething like:
template<typedef t=""> PlugNewModule()
{
UINT ID = T::IDD;
CRuntimeClass* _pRTC = RUNTIME_CLASS(T);
...
}
This way is easier because we just write
PlugNewModule<robctrlpage>();
instead of
PlugNewModule(RobCtrlPage::IDD,RUNTIME_CLASS(RobCtrlPage));
but i cannot compile  Why ????
I am using Visual Studio 6.0
Thanks !

Hi! Your post does not show <s and >s properly, next time you can check the "Display this message as-is (no HTML)" option (just above the edit area). Nevertheless, I've managed to read it through the source code of the page.
As for the problem, the correct syntax for calling the member function is
pMainFrame->template PlugNewModule<RobCtrlPage>(); Try it (if you please ) and tell us if it worked. Even so, it's possible that you experience some problems (due to a bug in VC++) resulting in the function being called for a type different to what you specified! If so, please report it back, the thing could possibly be workarounded.

No, it doesn't.
I've got ...

I would like some help. I need source code that will recursively search the registry and delete text found. It would need to work on 95/98/NT/XP/2000. Any ideas? Any help is appreciated.
Thank You,
Derek

I'm looking to return a list (perhaps in a list box) of all keys (ALL TEXT) that were found. If that Text appears anywhere in registry I want it added to my list. Then I can select/deselect what I wish and then delete the selected items. Allow someone to highlight and delete specific ones.

In my MFC application running on Win2k, the following code
fails in a worker thread, but succeeds in the main thread.
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
servaddr.sin_family = AF_INET;
servaddr.sin_port = htons(PORT);
servaddr.sin_addr.S_addr = IP;
int ret = connect(sockfd, (struct sockaddr *)
&servaddr, sizeof(servaddr));
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
In the worker thread, the error is always WSAETIMEDOUT,
never succeeds! But the same code in an applicaiton running
on WinCE works well! What's wrong with it?
Thanks a lot!

I believe you need to use a UI type thread instead of a worker thread because the worker thread doesn't have a message pump..
