Check CCommandLineInfo or, if you want to do the things as in console programs, use __argc and __argv.

also you can customize CCommandLineInfo with your own derived class and then pull arguments out as you need them.
You can do some nifty things this way.

have an app which, upon starting, creates a splitter window. One of the two panes (call it the one on the right) is simply a CFrameWnd. However, at a later time (specifically when the user clicks on something in the left pane), the CFrameWnd in the right pane is supposed to be used to house a CFormView. The initialization code (ie. the code to setup the new right pane) is called from within the left pane's code. Now, the form view shows up just fine; however, I don't seem to be receiving any events. For example, if I click on an edit box, it never receives the focus. If I click anywhere on the form, it doesn't receive the event, etc. I don't know if it matters if the CEdit controls are created dynamically on the form view or not...I did something similar to this before, but for some reason, this time around I'm not getting any events.
The form view itself is setup/created in a separate COM object. So, the calling code (from the left pane) is basically:
iCOMObj->initView(pParent); // pParent is the right pane's frame
pParent->SetActiveView(...);
pParent->RecalcLayout();
and within the actual COM DLL (ie. the initView method):
// since the COM object is a derivative of CFormView, we call
// Create (using pParent as its parent) to set this up
Create(...);
ShowWindow(SW_SHOW);
SetDlgCtrlID(AFX_IDW_PANE_FIRST);
...now, I'm not sure if this is the right way to do it, but the form does show up. It's just the messages that don't seem to be trapped. Is there a correct "order" to do this kind of thing in, given that the actual form is in a separate DLL?
Any suggestions/help? Thanks a bunch guys!

Well,
I can vaguely remember having had a similiar problem.
In fact it was the creation of the view by itself. Create tells the child who is the parent, but the parent will never know, that it has childs. In this case the parent must do the creation of the view.
I think a pParent->CreateView(...) will help in this case.
Then the view is created by the parent, while otherwise the child is attached to the parent.
For the needed values to use CreateView, please have a look at the documentation. As far as I can remember this works only for CFrameWnd and its derivates.

I thought about that. However, CreateView is normally used for non-CView derived classes, and the View I'm trying to set to the Frame is a derivative of CFormView. What would using CreateView accomplish since this is the case? Also, like I said, I've done something like this very similar, and it has worked. I gave the CreateView a try anyways, but it didn't seem to help. :\ I'll keep plugging away at it. Thanks for your input!

Is GetTimeZoneInformation() what you are after?
|
|

I explored this recently, and basically gave up (it was only a pet project, and I wanted to do .NET UI, not registry mangling and raw byte juggling.
There is no API way to enumerate Time Zone Information (neither Win32, nor .NET)
Time zone information is stored in a very strange format in the registry, under
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Time Zones\
The format is explained in a Knowledge Base article ( Q115231, search for TIME_ZONE_INFORMATION)
You basically have there:
- Name strings
- an Index (probaly for the correct sort order, since the registry has none by itself)
- a "MapID", which is probably used to shift the world map in the "select time zone dialog while windows setup
- a TZI binary structure with the actual time shift and DST switch information
(it basically indicates month, weekday and time of the switch, and which week of the month, using 5==last. very weird indeed)
You could use this information to re-build a TIME_ZONE_INFORMATION structure, then use SystemTimeToTzSpecificLocalTime (however, this works only on NT-based systems). Or you do the claculation yourself (grccch....)
Anyway, if you work your way through it, it would be nice if you can post an article I could blatantly rip off

Unfortunately, I don't believe that there are any APIs for accessing the time zone definitions stored in the registry. KB article Q221542 discusses how to decode the registry information using VB. It provides sufficient information to do it in a real language, such as C++.
Good luck on this. I've found messing around with time to be one of the most difficult programming tasks that you can attack. If you think you have it exactly right, you haven't looked at the problem hard enough.

Hi,
I need a little function that receives the actual CPU load of the system. It should work with Win98 and WinXP (maybe two functions) but without a need to install special components (performance monitor or something). Do you know a way to do this?

Hi all,
in my W2K I right click on a file, go to properties, click on the 'Security' tab, click on 'Advanced', click on the 'Owner' tab, and I see the owner of a file.
How can I get this owner for a file in my MFC 7 application?
I'd appreciate any ideas!
Thanks a lot!

Something like this:
bool GetOwner( LPCSTR lpszObjectName, CString &strOwner, CString &strDomain )
{
bool bResult = false;
PSECURITY_DESCRIPTOR pSecurityDescriptor;
PSID pSidOwner;
SID_NAME_USE rSidNameUse;
DWORD dwAccountSize,
dwDomainSize;
char *pszAccount,
*pszDomain;
strOwner = _T("<Unknown>");
strDomain = _T("<Unknown>");
if (GetNamedSecurityInfo((LPSTR) lpszObjectName, SE_FILE_OBJECT, OWNER_SECURITY_INFORMATION, &pSidOwner, NULL, NULL, NULL, &pSecurityDescriptor) == ERROR_SUCCESS)
{
dwAccountSize = 0;
dwDomainSize = 0;
LookupAccountSid(NULL, pSidOwner, NULL, &dwAccountSize, NULL, &dwDomainSize, &rSidNameUse);
pszAccount = new char[dwAccountSize];
pszDomain = new char[dwDomainSize];
if (LookupAccountSid(NULL, pSidOwner, pszAccount, &dwAccountSize, pszDomain, &dwDomainSize, &rSidNameUse) == TRUE)
{
strOwner = pszAccount;
strDomain = pszDomain;
bResult = true;
}
delete [] pszAccount;
delete [] pszDomain;
LocalFree(pSecurityDescriptor);
}
return (bResult);
}

Hi, everyone!
After invoking getline, I want to know what is appended at
the end of "output" in my case. It seems it is not \0. But
"strlen" function returns OK.
Output is:
--------
12
2
50
3456789
7
57
123456789
9
57
--------
Source codes:
--------
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
{
char input[] = "12\n3456789\n123456789";
char output[30];
istringstream is(input);
while (is.getline (output, sizeof (output), '\n'))
{
cout << output << endl;
cout << strlen (output) << endl;
if (0 == output [strlen (output) - 1])
{
cout << "Null is appended! " << endl;
}
cout << unsigned int (output [strlen (output) - 1]) << endl;
}
return 1;
}
--------
Thanks in advance,
George

You checked for "0" in the if-statement. Check for "\0."
if (output[strlen(output) - 1] == '\0')
{}

Hi
I have overriden OnInitialUpdate on a CFormView derived class that is implemented using DECLEARE_DYNCREATE and added to a splitter window but the overriden OnInitialUpdate never get's called.
Does anybody know why?
Thanks

It's too bad to say.  ^^
I created one dialog with one parent.
After creation, I tried to change my father.
Because of my application logic, it kills it's parent.  .-
So, I tried like this,
SetParent(NULL) or SetParent(My friend's father)
But It does not work.
Is it impossible to change parent?
It's me, nine. nine for you.

Hello,
Can anybody tell me how can I get a list of the exported functions from a .lib file. The library is just a statically linked win32, compiled from Fortran I think.
I've been looking at the Lib utility, using args such as /list, but I can so far only get the list of modules within the library , not the actual function prototypes.
Thanks,
John

How to find default browser in the system (exe file)??

I happen to have written this a few days ago:
#include <iostream>
#include <string>
#include <windows.h>
#include <fcntl.h>
#include <io.h>
#include <sys/stat.h>
static bool encuentra_programa_asociado(
std::string& programa_asociado,const char* extension)
{
char temp_path[MAX_PATH];
if(::GetTempPath(sizeof(temp_path),temp_path)==0)return false;
std::string str=temp_path;
str+="xxx.";
str+=extension;
int file=-1;
if(::_access(str.c_str(),0)!=0){
file=::_open(str.c_str(),_O_CREAT|_O_RDWR|_O_TEMPORARY,_S_IREAD|_S_IWRITE);
if(file==-1)return false;
}
char buffer[MAX_PATH];
if((DWORD)(::FindExecutable(str.c_str(),"",buffer))<=32){
if(file!=-1)::_close(file);
return false;
}
programa_asociado=buffer;
if(file!=-1)::_close(file);
return true;
}
static bool encuentra_browser_defecto(std::string& browser_defecto)
{
return encuentra_programa_asociado(browser_defecto,"htm");
}
int main()
{
std::cout<<"browser por defecto: ";
std::string str;
encuentra_browser_defecto(str);
std::cout<<str<<std::endl;
WinExec(str.c_str(),SW_SHOW);
return 0;
}It's in Spanish, but I guess you'll be able to figure it out anyway.
