Use LoadImage API if you want to load from the disk.
Hope this helps,

Command line parameters with MFC

I want a small MFC application that picks up paramters from the command line.
There are command line parser examples but all of them assume you already have the command line to parse.
Any suggestions as the VC++ help refers to ocnsole apps.
Thanks.

m_lpCmdLine member of CWinApp class contains command line string. You may parse this string in InitInstance() Cool | :cool:

Console Hangs after printf.

We are using Visual Studio .Net and dump a lot of debug info of our application to a console. Normally this is not a problem, however sometimes the console hangs and I cannot set the focus to the debugger anymore. And if I start the task manager, the whole system seems to hang.
We do use multiple thread to log information to the console, so I created the threads with _beginthreadex instead of CreateThread, but that does not seem to make any difference. Any one got a clue why this might be happening?

Maybe you need to make calls to printf thread safe, by using a CRITICAL_SECTION object....

void theadsafe_printf(char *lpzText) {
EnterCriticalSection(&cs);
printf("%s",lpzText);
LeaveCriticalSection(&cs);
}

Use InitilizeCriticalSection() to create the cs object.
and DeleteCriticalSection() when finished at the end of your app.

What you mean by "ascii"?? Do mean ascii value as an integer or ascii value as a string, i.e. Do you want to convert something like "979899" into "abc"?? Please clarify Confused | :confused:

Hello to everyody,

I want to draw a line thta connect two points...
I have to paint the line of one color...until here it's ok

But the problem is that I have to paint a piece of it of another color from one point to a distance done.

How can i do it? Because maybe i will need a line equation?

Thanks

You will definitly need line equation. If you require only two colors (not graduated), i suggest you to draw two lines instead of one using different color. You need to find the coordinate of dividing point using line equation etc.

Hi,

I change the font of the Window...and when i do DrawText it doen't work...with TextOut YES but with DrawText NOT...why? How can i do it with DrawText?

This is the code i use to set the font

CFont font;
LOGFONT lf;
memset(&lf, 0, sizeof(LOGFONT)); // zero out structure
lf.lfHeight = 12; // request a 12-pixel-height font
strcpy(lf.lfFaceName, "Arial"); // request a face name "Arial"
VERIFY(font.CreateFontIndirect(&lf)); // create the font

// Do something with the font just created...
CClientDC dc(this);
CFont* def_font = dc.SelectObject(&font);
dc.TextOut(5, 5, "Hello", 5);
dc.SelectObject(def_font);

// Done with the font. Delete the font object.
font.DeleteObject();

Thanks

if you want to convert a CString, I used the following once in a similar situation.
define the next:

#if defined (_UNICODE) || defined (UNICODE)
#define _tcstombs wcstombs
#else
#define _tcstombs strncpy
#endif

//in your code you can then convert CStrings to ascii strings--

CString sOriginalStr;
.... //somewhere here sOriginalStr gets a value
char* ascStr = new char[sOriginalStr.GetLength()+1];
_tcstombs(ascStr, sOriginalStr, sOriginalStr.GetLength()+1);

.. //do your thing with the ascistring

delete[] ascStr;

Hope this gets you along...

you can easily assign the ascii value to an integer variable....

int i;
char c='A';

i=c; // i is now 65.

Hi,

I would like to create an ActiveX and I would like to resize the window to an specific size when the user tries to resize it. Someone has told me I have to use WM_SIZE adding all the code required inside it.

Which is this code? I have to use GetWindow?

Help please

Thanks a lot

this can't be TRUE as MSDN state that the application must not send WM_SIZE message to it's WINDOW

better use api's like [MoveWindow] and [SetWindowPos]
