Assuming you function is
fn(char* p)
just get a local pointer that you initialize to "p", and whenever you reach a non-space you
*p++ = *local++;
and whenever it is a space you just increment "local".

Hello,
I want to resize an edit control in my Cdialog derived class :
void CMyDlg::OnSize(UINT nType, int cx, int cy)
{
CDialog::OnSize(nType, cx, cy);
GetDlgItem(IDC_EDIT_TEXT) -> SetWindowPos(NULL, 0, 0, cx, cy, SWP_NOMOVE | SWP_NOOWNERZORDER);
}
But my app crash... why ??
|
|
|
|
|
The OnSize is first called, before the dialog window is displayed and GetDlgItem returns NULL.

Hello, I need to be notified somehow when the mouse hovers above
a button on my toolbar and I need to know which button it hovers
above. I was under the impression that if I created the toolbar
with the style TBSTYLE_REGISTERDROP I could catch TBN_GETOBJECT, but
it never gets generated, it seems. What is the most straightforward way
to accomplish this?

catch the WM_MOUSEMOVE message for your button:
LRESULT CALLBACK WindowProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
);

When I loaded the ".dsw" file into the VC++ IDE, a message popped up saying that VC++ was unable to load the ClassView information file.
Yes, there was no ClassView information shown after the loading took place, though ResourceView and FileView were present!
Might anyone know why this occurred, and how I may get back ClassView? I did try reloading the program several times, but each time it was the same.
Thanks!

I'm assuming you're referring to VS6.
Usually this problem is caused by your classview file (.ncb) being read-only, check for this first of all. Otherwise delete any existing .ncb file and restart VS, it will then rebuild the classview file from scratch.
Hope this helps,
Jason.

This can also happen when you have more than one instance of the IDE openning the same workspace.

You have an interesting point there, because while there are two distinct projects being worked on (residing in two separate directories, with different names) the files both projects have, are about 99% the same.
Both projects were loaded into their own respective workspace, but only the first one showed the ClassView. The second project with its different name, located in a different directory and loaded into its own workspace, did not show its ClassView.

In VC projects there is an option to choose Runtime library ,
Project-Settings,
C++ Tab
Category:Code generation
Use of runtime library: Multithreaded DLL.
I Want to understand about this option, what difference would it make on my application if I make it Single thereaded.
Thanks in advance.

You will not be able to safely create multiple threads.
It uses libraries that are multi-thread safe when you select the multithreaded libraries, as well as adding functions that are only specifically used in multi-threaded applications.
The difference between the multi-threaded and single-threaded libraries is that multi-threaded functions serialize access to global data to prevent common problems that occur in MT apps. If you try to use a single threaded function or library in a MT environment, undefined behaviors could possibly occur.

Hi,
how can I create a popup menu and it should *not* be repositioned by Windows? At the moment my popup menu is repositioned when it would be party invisible (across desktop border. I need to avoid this in my current dialog, partly visible is really wanted!
thx for help.

I don't think this is possible. TrackPopupMenu() always ensures that the whole menu is visible. If the menu is taller than the screen, scroll arrows are added so the contents can be scrolled.

Hi there dear coders...
how do I create a bold font from an existing font?
//CDC* pDC
CFont fontBold, *pFontOld;
LOGFONT lf;
VERIFY(pDC->GetCurrentFont()->GetLogFont(&lf));
lf.lf?????=1; //what do I set here???
VERIFY(fontBold.CreateFontIndirect(&lf));
thanks for your help!

From MSDN:
lfWeight
Specifies the weight of the font in the range 0 through 1000. For example, 400 is normal and 700 is bold. If this value is zero, a default weight is used.
The following values are defined for convenience:
Value Weight
FW_DONTCARE 0
FW_THIN 100
FW_EXTRALIGHT 200
FW_ULTRALIGHT 200
FW_LIGHT 300
FW_NORMAL 400
FW_REGULAR 400
FW_MEDIUM 500
FW_SEMIBOLD 600
FW_DEMIBOLD 600
FW_BOLD 700
FW_EXTRABOLD 800
FW_ULTRABOLD 800
FW_HEAVY 900
FW_BLACK 900

thx, i was confused by those many posibilities... I didn't get them, e.g. no idea what a FW_SEMIBOLD is.
now it works!

I find the documentation confusing sometimes myself.
I have not used any values for lfWeight besides the standard (regular and bold) ones, but I assume the other values are are for degrees of bold (which probably does nothing at normal point sizes).

Hi.
I would like to know is it possible to apply polymorphism to overloaded operators? For examples, is it possible to rely on polymorphism via creating virtual overloaded operators and friend functions?
Consider the ostream and istream for instance. I would like to design a hierarchy such as this.
-----------------------------------------------------------------------
Base *pB;
Derived *pD = Derived();
pB = dynamic_cast<base *="" />(pD);
// I would like this line to call an ostream friend function in the *Derived* class.
cout << *pB;
----------------------------------------------------------------------
My code might be off. Nonetheless, the point I want to get at is applying polymorphism to overloaded functions and friend functions, especially iostream.
Thanks,
Kuphryn

You can create virtual operators.
If you need to have a friend function in order to properly create the stream operator, you may simply want to create a function for the Base class, then create a virtual function in the Base class that gets called to actually generate the output.
