if you are using Visual Studio, just try something bellow:

1. Select File -> New -> Projects -> Win32 Static Library
2. Specify Project Name and Location
3. Add all your files into project with command: Project -> Add to project -> Files
4. Make any setting that you need and build

In order to re-use library function:

1. Include headers which declare functions into file where you plan to use that functions
2. In project setting, at Link tab -> Object/ Library modules, type the path points to your lib file
3. Build

There is an easier way to re-use library function from lib file if you add that library project to your current project and set the dependency between them correctly (Project -> Dependencies)

Have fun.

Problems with Mfc-Program: black screen

Hi everybdoy!
I developed a program under Mfc and VisualC++, SP5. After installing the program and all the components (i. e. controls) under Win98 (not SE), I get a black screen. When I click around and hit a control, it appears back, the rest stays black.
Under Win2000 it works fine without any problems.

Now I need your help:
Where could the problem be located?
How can I resolve this problem?

Thank you very much for your help
Brennivin

what do you mean by black screen? does the program or the os not react anymore?

Don't try it, just do it! Wink | ;-)

No, there is just no picture! If you finish the program, it appears back and you can work on without any problems. And if you click left on a control, you see just this control, the rest is black.

there are a couple of articles here at cp that show a ballon help one is CPPTooltip and another is by shog.

calculate the coordinates of ur tray icon (easier said than done Smile | :)

)
and show the ballon help

i can't even remember what my point is now, but anyway, i'm correct

On XP, use the IUserNotification interface provided by the shell. On earlier OSes, you'll need to handle adding/removing the icon yourself.

Thanx for the advice, but my software is targeted for varity of OS's so i cant use it even if i want to.

But i figured out that NIF_INFO in NOTIFYICONDATA by using Shell_NotifyIcon does the samething.

But i havent test it yet but seems like that what i am looking for.

simple postfix decrement

I have the following snippet of code:

for(int i=nIndex; i>=0; i--){
	if(csBuff[i]==chDelim || csBuff[i]==LF) break;
}

I thought it would decrement i until a deliminator was found or until i == 0 in which case it would not execute anything inside the loop, nor would it decrement i anymore either...

to my surprise i is -1 and it's driving me nutts...

someone tell me this is normal or indicate the bug in my code....

Should I just test after the loop and make sure -1 becomes ZERO...like I thought it would and all post code assumes as well...?

Thanks

No, the loop runs as long as the condition i>=0 is true. When i is 0, the test becomes 0>=0 which is true, so the loop runs. If you want to stop when i is 0, the test should be i>0

I understand true would cause the loop to iterate again, but I still can't get the code working...

I'm trying to extract a word given an offset into a buffer using space as delimiters, this is what I have so far and it doesn't work...and I have no idea why...

// Find the index for the deliminator that the word starts on
for(int i=nIndex; i>0; i++){
	if(csBuff[i]==chDelim || csBuff[i]==LF) break;
}
	
// Concatenate each iterated character onto csWord
for(int j=i; j<csBuff.GetLength(); j++){
	if(csBuff[j]==chDelim || csBuff[i]==CR) break;

	csWord += csBuff[j];
}

Any idea?

Thank again Smile | :)

Are you sure that i++ is intentional? That, coupled with the i>0 condition, means that this is potentially a "forever" loop. The only thing that would cause the loop to exit, besides i becoming negative after about 2³¹, would be if either of the conditions in the if statement were true.

It is normal.

Remember that the syntax of for statement is defined as:

for(init_statement ; condition ; expression) exp_2;

The expression (in the case, i--) will continue to work (decrement) till the condition becomes false, then the execution leaves the for loop. In the case, i>=0 is still true while i is zero at that time, thus the expression (i--) will be executed once more to expect the condition to become false.

If you hope it exit the for loop at the time i = 0, you may write this way:

for(int i = nIndex; /* Nothing */; i--)
{
	if(csBuff[i] == chDelim || csBuff[i] == LF)
		break;
	if(0 == i)
		break;
}

Help! cannot use CTypedPtrList

hi, guys
i need to use a CTypedPtrList templet structure in my program.
here is my code: (CFreqStandard is a class which i derived from CObject and it's basically used to store some data)

class CSDIgDoc : public CDocument
{
protected: // create from serialization only
CSDIgDoc();
DECLARE_DYNCREATE(CSDIgDoc)
protected:
//CTypedPtrList<coblist,cfreqstandard*> FreqList;
//CString StandardName;

CString StandardName;
CTypedPtrList<coblist,cfreqstandard> m_FreqList;/////////////////////

// Attributes
public:

// Operations
public:

// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CSDIgDoc)
public:
virtual BOOL OnNewDocument();
virtual void Serialize(CArchive& ar);
//}}AFX_VIRTUAL

// Implementation
public:
virtual ~CSDIgDoc();
#ifdef _DEBUG
virtual void AssertValid() const;
virtual void Dump(CDumpContext& dc) const;
#endif

protected:

// Generated message map functions
protected:
//{{AFX_MSG(CSDIgDoc)

//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};

but when i compile i always get an error in the line
CTypedPtrList<coblist,cfreqstandard> m_FreqList;
it shows that "'CTypedPtrList' : missing storage-class or type specifiers"
what is the problem in this case? Cry | :((

Thank you very much in advance

You never defined the types to use for the template, like this for example:

typedef CTypedPtrList<CObList, CMyObject*> m_FreqList;
Have a look to this article[^] of MSDN for a sample.

I declear a CTime valiable and set it's value before 1970-1-1, it will cause a assertion failed error(timecore.cpp), I realized that 1970-1-1 is the defaule value for CTime, anybody encounter this problem before? please help me out, thanks a lot.

CTime objects can contain times from 1970-1-1 to somewhere in 2038. (you should check the validity of the input yourself)
if you want to have dates outside that period you can use the COleDateTime class.

I have been using FindFirstUrlCacheEntry/FindNextUrlCacheEntryA/DeleteUrlCacheEntry without specifying wininet.lib in the object/library modules in my project options.
But when I added the cache group functions (FindFirstUrlCacheGroup, etc), I could not build my project without adding wininet.lib to the object/library modules.

any ideas why this is so?
