A stupid question that I just can't answer...

My class inherit from CFrameWnd, how do I set the window size to be different than the default size when it pops up ?

Override PreCreateWindow(CREATESTRUCT& cs) and change the values for cy and cx of cs.

LInking Statically to MFC

OMG I can't believe I forgot the answer to this question. A long layoff (in the land of VB) and coming back I can't remember. When you statically link MFC do you have to include in your distributable the mfc70.dll? Or, does the user even need it? I know dynamically linking they would need it but can't remember about statically linking.

TIA for such a dumb question.

No - static linking means everything needed from MFC is linked into the app statically. No MFC DLL is needed.

Binary STRINGTABLE Resource Format

I am creating a 'ResDiff' tool to determine if two modules have similar or different resources.

I can already load all resource blocks as binary blocks of data and detect if they are the same or not, but I am having trouble decoding the STRINGABLE block, which can contain up to 16 resource string entries each.

It seems MSDN is all over what the RC file format is, but is very unclear about what the binary format is once it is compiled into an EXE file.

Does anyone have a link they can point me to with an explanation or some sample code?

Thanks.

Problems with WM_VSCROLL PostMessage

Hi everyone,

I am trying to scroll a window by more than one unit at a time. currently I am doing this

[CODE]
for(int i=0; i<100; i++)
pParent->m_SkinList.PostMessage(WM_VSCROLL, MAKELONG(SB_LINEDOWN,0),NULL);
[/CODE]

I have my current code inside a for loop to make it scroll down multiple times and it works, but it freezes up my app until the for loop is done.

How can I scroll by multiple lines using a single PostMessage call? Can I scroll variably in a single call without using a for loop?

Thanks,
Greg

A SetFont problem

Hi all,

I have a question about SetFont.

Now I create a class that is derived from CWnd, and use SetFont to set a
font to it. Then I override the Paint function to display the content I
want. The problem happens there, no matter what font I set, when I draw the
text in Paint, it display with the same font, I think it is the system font.

How can I make the SetFont work?

Thanks in advance

if you are using DrawText or TextOut, you have to use CreateFont/SelectObject . SetFont doesn't do what you think it does.

something like this:

CFont fnt;
fnt.CreateFont(...);
 
CFont *pOldFont = dc.SelectObject(&fnt);
 
dc.TextOut(...);
or
dc.DrawText(...);
 
dc.SelectObject(pOldFont);

Thank you for your reply.

After reading your comment, I have another question. I have used SetFont to set a font to it. How can I know which font I have set when I want to use it in Paint function. Because my class is used by other people, I have to use a generic way to know which font they set. Actually I have tried another way, I override the SetFont function in my class, and remember the font they said. It worked. But because the SetFont is not a virtual one, when they use a CWnd pointer to call the SetFont function, my SetFont will not be called.

Thanks again.

Sure I did.

Some of my code is below:

void CColItem::OnPaint()
{
CPaintDC dc(this); // device context for painting

// TODO: Add your message handler code here
CRect rect;
GetClientRect(rect);

CFont *OldFont = NULL;
OldFont = dc.SelectObject(GetFont());

..............
dc.TextOut(xText, yText, strWindowText);
..............

dc.SelectObject(OldFont);
}

Thanks again

The painting code is right. It sounds more like that the code you're using to test it is somehow not passing the right font. Or perhaps you're creating a font that's local (allocated on the stack) and it's going out of scope. SetFont takes a pointer. If that pointer becomes invalid, I'd suspect that the dc.SelectObject( GetFont() ); would fail.
If you're unsure, post the code that calls SetFont and I'll take a look.

Thank you for your information. However it is not that case.

Below is the answer from MS newsgroup:

"
There is no default implementation of WM_SETFONT and WM_GETFONT. You
need to implement these message handlers to store and return the current
HFONT (or NULL as the case may be), and Invalidate if LPARAM is TRUE.
IIRC, ClassWizard won't help with these, so you'll need to add them
manually using ON_MESSAGE macros in your message-map, and remember that
the prototype is 'LRESULT memberFxn(WPARAM, LPARAM)'. In your WM_PAINT
handler, you will need to SelectObject the currently stored HFONT (if
there is one) into your CPaintDC, and SelectObject it back out again
when you're done.

I follow his instruction. It works well.

Anyway, thanks again.

When you call SetFont(), are you doing something like this?

CFont font;
font.CreateFont(...);
SetFont(&font);

If you do this, the font will be destroyed as soon as the CFont object goes out of scope, so the default system font will be returned by GetFont(). Make sure you either detach the font (CFont::Detach()) or use a font object that is a class member.

Hope this helps,

Ryan

hi all

thakns for your help so far

at the moment im using the following to convert a string to long

CString stud_id = "00123"
long l;
l = atol (stud_id);

which works ok, but it removes the leading zeros off
so im left with l = "123"

when i want l to = "00123"

does ne1 have ne ideas how to solve this

thanks

si

The long data type doesn't work like that - 00123 and 123 are identical, because they are stored internally as a binary number, instead of the characters that make up the digits. If you go the other way, look at this:

<br />
long l=123;<br />
CString str, str2;<br />
str.Format(_T("%.5d"), l);   // str contains "00123"<br />
str2.Format(_T("%d"), l);    // str2 contains "123"<br />

Note that if you write:

<br />
long l=0123;  // or 00123 for that matter<br />

Then a C/C++ compiler will treat the literal value as base-8 (octal) instead of base-10 (denary).

Leading zeros on a number has no significance to the value itself.
123, represented as a number implies an infinite number of leading zeros!.

123 == 0123 == 00123 == 000000123

If you, however, need to display your number with leading zeros, then you can either stick with your string representation, or use something like:

<br />
CString strValue;<br />
long nValue = 1234;<br />
<br />
// convert to string.<br />
// if number is less than 6 digits, pad with zeros.<br />
strValue.Format(_T("%.6ld"), nValue);<br />
<br />
// display to screen<br />
std::cout<<(LPCTSTR)strValue<<std::endl;<br />

Really? Tried e.g. sscanf lately? As any good C or C++ programmer should know, any number (including literals within the program itself) having a leading zero is an octal number.

Now, let's try to rephrase that statement. Smile | :)
