How do i compile a cpp program using cl.exe ?

you put nothing in the parenthesis, this function receives no parameters :

std::string str = "hello";
 
char* psz = str.c_str();
 
printf("%s", psz);

i can't convert from 'string' to 'const char*'

This is done by using std::strings member-function c_str(), which returns a const char* to the string contained.
You can the go through this const c-string on a char by char basis and copy anything save the extra spaces to another string.

Hope this helps.

you don't need to start a new thread again and again Sleepy | :zzz:

have you tried to type cl.exe /? in command line to have the syntax ?
and as it might be a bit too huge, have you looked in the msdn ? the information is obviously there

How about:

cl somefile.cpp

Obviously this is a very simplistic example. You'll need to add your own compiler switches (as has already been given to you).

For that i have written the following code.

POINT point; 
point.x=126;
point.y=83; 
							
HWND hwndListboxDlg = ChildWindowFromPoint(GetParent(hDlg),point); 
HWND hwndListbox = GetDlgItem(hwndListboxDlg,IDC_LIST4);
LRESULT iCount=ListView_GetItemCount(hwndListbox);

When i debug the application its find the handle for hwndListboxDlg ,but unable to find the
IDC_LIST4.

[GDI] x-offset when using Graphics::DrawString(...) [modified]

_NielsB24-Jan-07 0:01

Hello!

I am using the following Function to draw text to a screen:

Status DrawString( const WCHAR *string,
    INT length,
    const Font *font,
    const PointF &origin,
    const StringFormat *stringFormat,
    const Brush *brush
);

Works fine, but there is one major problem : even if I use PointF(0,0) as origin, the text is displayed with an x-offset (the concrete width in pixel seems to depend on the Font-Object I use within the DrawString - Function).

Any Solution about that? Is this a known bug or even a feature? Wink | ;)

Thanks in advance!

As I wrote, it seems to depends on the Font that is in use within the function call.

As the other guy said use COleDateTime, but do not use COleDateTime::GetCurrentTime...

From MSDN...

COleDateTime::GetCurrentTime. The current implementation calls the C run-time function time, which returns a time_t. This limitation isn't currently documented—it presumably took Chris's digging through the Microsoft Foundation Classes (MFC) source code to find it. (As Dr. GUI says, "Use the source, Luke!") Good job. Don't use this function if you need to be year 2038 compliant. Note also that COleDateTime has a constructor and assignment operator that take a time_t—don't use those either.

A suitable replacement will be GetLocalTime.

Hi,

I am working on a project that requires to generate a report after some testing. The report will include some text, one or two pictures and some tables. The dev environment is Visual C++. Did anyone ever work on similar task before? Is there any controls that I can use? Or is there any articles with detailed intro on how to accomplish it?

Thanks a lot!
David
