Oh sorry, pointed lines are :
real_T d; and
** real_T is the representation of double in this format, even if i write there 'double' appears again as error **
num.d = *uPtrs[0];
Thank you for your consideration!

9 what? September? Ninth day of the month?

So how are you currently extracting the date from the control?

Hi all,
OK, so lets say you have an application, lets call it app1. app1 may not have more than one process running at one time. And if another process was found restore the previous app1. This is where the problem comes in.
See the thing is the the second instance of app1 has been opened and the app sees that another instance is running (of itself), how will it diffrenciate between the two app window names, to bring the correct one to the foreground??
Really Hope this makes sense
Any ideas???
Thanx in advance

actually, it does use a semaphore/mutex, which name must be unique.
see this[^] class to understand what it actaully does.

So do you want to keep the second instance also running?
Or kill the second instance and bring the focus on the first instance that was already running?

Thanx for the reply...
"....Or kill the second instance and bring the focus on the first instance that was already running? ...."
Yes, I want to send a return code to the calling app (2nd opened application) so that it will see that another instance is already running, kill itself and cause the 1st instance to restore it's window.

There could be various solutions to this problem.
Preferrably using mutex's .
something like
HANDLE hMutex;
hMutex = CreateMutex(
NULL, // no security attributes
FALSE, // initially not owned
"SomeUniqueName"); // name of mutex
If this exists already return from the application.
Another option would be to use a shared variable and check for its value. Increment it each time an instance is created. If the value is greater than one you can just return from the second instance.
The third option would be to use the FindWindow function. You would get the handle to the window if it's already running.

"undeclared identifier" it seems you need to include a header file to mymenu.cppdid you include this file?
|
|
|
|
|
yes, as you can see in .cpp file, I had
#include <windows.h>
#include "resource.h"
|
|
|
|
|
check the Ignore HTML tags in this message (good for code snippets) check box 
|
|
|
|

sure you include but i cant see header file in previous your thread i saw only #include:) anyway these erros are only a thing a include

Hello everybody,
I've figured out that windows supplies an smart way to draw cutom elements via DrawFrameControl.
When drawing a radio button or a checkbox the question is where to place the text exactly. Of course it is no problem to figure out the settings for the standard settings (MS Sans Serif 8), but I wonder the windows internal logic for other fonts and sizes. I've used a lot of time to consider all values of GetTextMetrics, but I was not success full.
Has anybody found a rule where the text is placed exactly depending on font and font size?
|
|
|
|
|
now whats your problem?
|
|
|
|
|
Maybe the easisiest ways is to use some code to show my problem on drawing the radio button.
PaintRadioButton(CDC* pDC, const CRect& rcPos, const CFont& font, const CString& strText)<br />
{<br />
DWORD dwBackground = GetSysColor(COLOR_BTNFACE);<br />
CBrush brushBk(dwBackground);<br />
pDC->FillRect(rcRadioButton, &brushBk);<br />
<br />
CRect rcCircle;<br />
CalcCircleRect(rcPos, rcCirlce);<br />
pDC->DrawFrameControl(rcCircle, DFC_BUTTON, DFCS_BUTTONRADIO);<br />
<br />
CalcTextRect(rcPos, rcText, font, strText);<br />
pDC->DrawText(strText, rcText, DT_LEFT|DT_VCENTER|DT_SINGLELINE);<br />
<br />
}
CalcCircleRect(const CRect& rcPos, CRect& rcCirlce) is easy to implement, just center the box vertically and make an offset of 1 in the horicontal position. The size could be received through GetSystemMetrics(SM_CXMENUCHECK);
CalcTextRect(const CRect& rcPos, CRect& rcTextPos, cont CFont& font, const CString& strText) Is the thing what is missing. Do you know some magic formula how to calculate the exact position for the text depending on font, font size and text content so it looks exactly like the radio button controls?

Hello everyone,
Yahoo is using a technology called sign-in seal to protect password stolen. Check,
[url]http://mail.yahoo.com[/url]

Does any one know what it is and whether there are any documents/SDK supporting that feature? I have Googled, but only can find advertisements ...
