Try a ZeroMemory on strDest before using it.

Thank you Rage, It seems to have done the job...

Pasted from MSDN:
"The strncpy function copies the initial count characters of strSource to strDest and returns strDest. If count is less than or equal to the length of strSource, a null character is not appended automatically to the copied string."
You have to terminate the string yourself.
Rage suggested one way to it to be absolutely sure. Another way is to place a '\0' at the correct position, i.e. at the end of the string if you know where that is.

Take the function void foo(unsigned char * param). It does not change the value of the string (it's a Win32 API function, don't ask me why it's not const). Now i'd like to pass it the value of std::string MyString. I do this liek that
foo(reinterpret_cast<unsigned char *>(MyString.c_str()));
but this can hardly be the recommended way (it works, but it's bad). Any suggestions anyone ?

why not the simple static_cast ?
i can't see anything wrong otherwise...
|
|
|
|
|
static_cast gives a compiler error:
error C2440: 'static_cast' : cannot convert from 'const char *' to 'unsigned char *'
|
|
|
|
|
hum, yes, that's right (i have no compiler with me at the moment...).
does it work without any explicit cast ?
|
|
|
|

You cannot cast a 'const' value to a 'non-const' because that's the whole point of the 'const' keyword.
In this case you have to make a copy of the string and provide the second function with the copy.

You want const_cast.

Be sure the ES_MULTILINE style is set when creating the edit control.
Besides that, your sample code obviouly only displays "First", which is indeed one line of text.

Hi,
does anybody know how to resize a control or a CFormView view which contains the control when the view is nested in a CSplitterWnd Pane? I want the control to adapt its size when the size of the splitter window changes.
Thanks,
Frank.

I think you should add to your form a handler for WM_SIZE message (i.e. OnSize function) and do the adjustments of child controls here.
|
|

|

Thank you, it works. As in all other resizing dialogs. I don't know, why I've got problems with this. Somehow I thought that my CMDIChildFrame should handle the WM_Size message.

Hai all,
I have a dialog based programme.
-> I have Created CCustomStatic from CStatic using class wizard.
-> I havent inserted any CStatic Resource.
-> I created my static window in OnInitDialog() of dialogbox
st.Create(_T("my static"), WS_CHILD|WS_VISIBLE|SS_CENTER,CRect(10,10,150,50),this);
-> After this I have added OnEraseBackground() in my CCustomStatic and Wrote the following code
BOOL CCustomStatic::OnEraseBkgnd(CDC* pDC)
{
TRACE("\n ERASE BACKGROUND");
RECT rc;
GetClientRect(&rc);
CBrush brush(RGB(255,0,0));
pDC->FillRect(&rc,&brush);
return TRUE;
}
->But I didnt get a Static with Red Color.
->But Later when I added OnPaint Message Handler in my CCustomStatic class , I got Red colored Static Control.
->Why this is happening So.
->Here What is special with OnPaint() in CCustomStatic
Please Help me
Thanks in Advance

When using standard Win32 API you need to process the WM_CTLCOLORSTATIC message and return a HBRUSH to get a custom background. I don't know if this applies to MFC but hopefully it will give you something to think about.

Hi Steve,
When I checked in my CCustomStatic Messages
I didnt get WM_CTLCOLORSTATIC
I found WM_CTLCOLOR, and I used it as u said for WM_CTLCOLORSTATIC
And I got my Static control's color changed.
But Still I am doubted with my Onpaint() Magic in CCustomStatic.
Thanks
George
