Any API is there to find wheather the system is locked.
|
|
|
|
|
define "system is locked"
|
|
|
|
|
In my definition, this is a locked system:
SetPriorityClass(GetCurrentProcess(), REALTIME_PRIORITY_CLASS);
int x = 0;
while (true)
x++;
I see dumb people

Hi everyone,
I have a weird problem. I have a function definition like
void SetUp(double **)
Now I have an array:
static double ERBbCoeff_22050[6][7] = {.... values...};
Now when I try to call the function SetUp(ERBbCoeff_22050), it throws the error...cannot convert parameter from double[6][7]to double**. However, I thought a 2D array could be represented as pointer to a pointer.
Obviously, I am missing something here. Anyone know what is going on? I would appreciate any help.
Thanks again,
Pankaj

Try declaring the function SetUp as:
void SetUp(double *array[7]); And then pass the array like before:
SetUp(ERBbCoeff_22050);

Hi Dominik,
Nope even that did not work. I tried it before. It still says:
error C2664: 'Beat::FilterBank::SetUp' : cannot convert parameter 3 from 'double [6][7]' to 'double *[]'
This is really weird. Do not worry, I will try to find a way.
Thanks for all your help,
Pankaj

Perhaps pass the array like
SetUp(&array[0]);
This helps?

Hi RChin,
Thanks for your reply. Your reply seems to be lost though! But it did not work. Now I get the following error,
c:\Pankaj\TestProjects\BeatDetectionNew\BeatDetection.cpp(180): error C2664: 'Beat::FilterBank::SetUp' : cannot convert parameter 3 from 'double (*__w64 )[6][7]' to 'double ** '
I always thought I could pass it as a pointer. I mean we can pass an array as a pointer

this will compile:
<br />
static double arrVar[2][2]={1,2,3,4};<br />
SetUp( &arrVar[0][0] );<br />
or
<br />
static double arrVar[2][2]={1,2,3,4};<br />
SetUp( arrVar[0] );<br />
if you declare the function as
void SetUp(double*)
Your function will have to know the dimentions of the given array.
However, you might have a valid reason for declaring the input parameter as a pointer to a pointer.

Hello,
it works if you call your function like
SetUp((double**)ERBbCoeff_22050).
|
|
|

hey, it works!!
Thanks a bunch!

hello @all,
i have a mfc-program and two CStrings.
i would like to connect these, but everyone in its own line, e.g. they should be separated with a Return.
CString one="123";
CString two="456";
CString combination="123
456";
i posted it yesterday and somebody said, that i can use this:
combination=one+0X0A+0X0D+two;
but when i save my CString combination into a txt-file, the CString are not in its own line, there is only a 'symbol' between them.
what must i do, that the CStrings are in their own lines???
thanks
sunny

use "\n"

Help me! I'm turning into a grapefruit!

It should be :one +0X0D+0X0A+two;
|
|
|
|
|
why not just:
combine=one+"\r\n"+two;
includeh10

Hi,
I am currently developping an outlook plugin using MAPI.
I inserted a new toolbar button in the new message window of outlook.
Now when the user clicks on this button, i need to get the info from the mail he has been creating (ie: recipients email adresses , to, cc, bcc, subject and body and attachments)
In order to do that, I retrieve the IMessage object using the IExchExtCallback ::GetObject method.
The problem is that the IMessage object doesnt seem to be up to date with the info the user just typed in.
So is there any way to synchronize the IMessage object with the latest info typed in by the user, or is this not the correct way to retrieve the infos i need at all ?
Thanks for your time

I have a custom CView that has a CListCtrl inside and I want to handle whatever the user does in the ListCtrl in my CView class. (I think that is the appropriate MFC way besides making a custom ListCtrl, right ?)
so I put the ListView inside an tried in my CView:
direct handling in the messagemap like OnLButtonUp()
this just executes when I click outside the list.
so I tried OnChildNotify(), which is executed when I add an item in the initialisation, but that's all, never else.
Basically I just want to know if the user has clicked in the list, selected something, everything you also get in the listctrl.
Where is the correct place to handle these things ?
(I also have another view with a combo and an edit ctrl and I think, they'll give me the same problem, so a general answer to handle control messages in CViews would be nice.)

You can get notified about many things by adding an ON_NOTIFY handler to your dialog's message map. You can then handle mouse- and keyboard-events as well as control-specific envents, like LVN_COLUMNCLICK when a column of your list ctrl gets clicked.
|
|
|
|
|
It's not a dialog and so classwizard doesn't show me WM_NOTIFY when I try to add a message handler.
Does adding this manually work ?
|
|
|
|
|
As the control sends that message to its parent it should work. However I'm not really sure as I only tested such stuff on dialogs. Nevertheless you should try adding it manually.
But as I just saw, WM_NOTIFY is not sent by standard controls like combo boxes, edit fields etc - in contrast to list ctrl, which does.

It worked, I think I have to interfere with the Classwizard-done messagemap then
thx
