It's giving you a syntax error? Could you post the code (if it's not millions of lines that is) so I could have a run-through?

Inside a DLL, Can I find which process is calling the dll ? Thanks

GetModuleFileName()

How about a bit more info:

If you want the process name use GetModuleFileName()
If you want the PID use GetCurrentProcessId()

Thanks

GetModuleFileName() worked. Thank You!

Can you use a string object.
Ex. CString str;
str.Format("%d", nNumbers);
str.GetLength();

How about capture keystrokes ?

Re: count digits in an integer type

1-May-02 4:27

or you can use this approach:

char buff[6];
int i = 2632;
int len;

sprintf(buff, "%i", i);
len = strlen(i);

Re: count digits in an integer type

1-May-02 4:32

or you can use a simpler aproach:

int len

if (i < 10)
len = 1;

if (i < 100 and i > 9)
len = 2;

if (i < 1000 and i > 99)
len = 3;

if (i < 10000 and i > 999)
len = 4;

if (i < 100000 and i > 9999)
len = 5;

very simple, but since you can't use conversions, i'd use that one.

Try this -

int get_NumDigits(int x)
{
return (int) (1+log10(abs(x)));
}

Thats a nice solution except of course what if x is 0?

Log10(0) = error!

if (x != 0)
 return (int)(1 + log10(abs(x))) ;
else
return 1 ; // 0 is 1 digit wide
}

Yes,

thats a good safe check. the code wont crash but will report num digits in zero to be zero.

Roger Allen wrote:

Maybe from a printing point of view, but I think from a math viewpoint, num digits in zero = zero. (if you define num digits of an integer to be the number of times you have to divide the integer by 10 to get a value to zero)

I better get back to work .. Smile | :)

You could just divide by 10 in a loop and count how many times you executed the loop until the result was zero.

int val; //find the length of this int
int len = 0;

for (int i = val;i;i = i / 10)

count how many times you can divide by ten before you get a 0 answer.

Performing registration (Halts)

I have a COM dll and VC++6 IDE hangs while performing registration. I even tried registering using "regsvr32" from command prompt and still no luck. I see the process "regsvr32" in the task manager and it's idle...

Any pointers. Thanks.

I found the problem..

After completing the build process, VC registers the COM dll. ie it makes a call to DLLRegisterServer(). I overrided the "InitInstance" and the code in Initinstance is resposible for this problem. I have deleted my code from InitInstance() every thing works fine.

Batch File

Hello,

I need a bit of help writing a batch file. In the line below where I have %1 instead of reading only one word I need to to read an entire string. So to do this I persume that I'll have to read the string from a file. So my question is how do I tell it to read from the file. Lets say the line I need to read is in c:\line.txt

echo %1 | C:\myexecutable --sendsms %2

Thanks.

My app cannot be moved or close, doesen't react to mouseclicks on the window

1-May-02 2:27

I have made an app in Visual C++, but i can't move or close it, it's like it doesen't react on mouseclicks (but the controls on the window works fine). however, the only thing that doesen't seem to work is mouseclicks on the app, when i right click on the app in the taskbar and press the "Move" menu item and then move it, it works, and the close command also works in that menu... here's the winmain code:

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
MSG msg;

ghWnd = CreateDialog (hInstance, MAKEINTRESOURCE(IDD_MAIN), NULL, WndProc);
ShowWindow (ghWnd, SW_SHOW);
UpdateWindow (ghWnd);

while (GetMessage (&msg, NULL, 0, 0))
{
TranslateMessage (&msg);
DispatchMessage (&msg);
}

return msg.wParam;
}

and here's the WndProc:

BOOL CALLBACK WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg)
{
case WM_DESTROY:
RegSave(hWnd);
PostQuitMessage (0);
break;
default:
return DefWindowProc (hWnd, uMsg, wParam, lParam);
break;
}

return (0L);
}

anyone know what could be wrong?

thanks all!

You should try handle WM_CLOSE (too).
WM_CLOSE is the first message that will be sent when you hitt 'X' (close) button in the upper-right corner of your app, and then you have to handle close functionality for that message, e.g. PostQuitMessage(0); and that function will cause a WM_DESTROY (I think)...

Understand!? Smile | :)

Thanks man! But i don't think that that's the problem. Cause it just doesen't respond when i click it, ie. the button doesen't even look like it's being pressed, it's just dead.

Thanks Smile | :)
