You really should provide more information if you want a useful response.
Is the viewer going to be in a modal/modeless dialog or a separate program and have you considered these alternatives?
Are the buttons you want to add going to be in a tool bar, plain buttons or owner drawn?

I noticed that the main.cpp in a Qt application has to contain the following line:
QApplication app(argc, argv).
I know that argc is the number of command-line arguments, and argv is that array list of command-line arguments. But, the question in my mind is: what are those arguments I'm passing to the constructor and at the same time cannot explicitly see? What is working behind the scences out there?
Thanks.

Could you clarify your question? As far as I can see the only arguments passed to the constructor are argc and argv, which are the command line arguments, there is nothing hidden.

I mean what arguments we have to pass.
|
|
|
|
|
it wouldn't surprise me if there were some esoteric QT command line params, but I'd guess that QTapplication consumes them so you can query the application object for them later

Whatever you want. See also the answer below by Maximilien.

To check the number of argument passed.
for example
if (argc != 3)
{
printf("usage: myapp <srcfile> <dstfile>");
// Here 0 = myapp
// 1 = srcfile
// 2 = dstfile
//Total 3 Arguments entered
return FALSE;
}
pszSrcFileName = argv[argc-2]; // Src is second to last argument
pszDstFileName = argv[argc-1]; // Dst is the last argument
by default no arguments are passed. Unless you have created a program that read a Command Line Arguments.

If you can put a break point in the constructor, you should be able to see the arguments passed to QApplication from the program entry point (main or WinMain)
The arguments are passed to the entry point via the command line, or form the application properties (right-click on the EXE).
The QApplication allows some default parameters. (see http://doc.qt.nokia.com/4.7/qapplication.html#QApplication[^] ).
I assume a QT developer can also add his own command line parameters by overriding either the QApplication and maybe a couple of methods to handle and parse the new parameters.
Other than that, I'm not certain what is the question.

Like grid control is it possible to add a fixed row in list control (clistctrl)
If i create a list control with LVS_EX_CHECKBOXES style then check box display in 1st column. Can i change check box position to any other column in list control
|

You can change the check box position by using this APIListView_SetColumnOrder ->[^]

hi to all,
I am writing a function to check access rights on file or folder using AclAPI.h
I am using following api's
GetFileSecurity()
ImperonateSelf()
OpenThreadToken()
MapGenericMask()
AccessCheck()
do i have to include
#pragma comment(lib, "advapi32.lib")
in my code or not.
Without including #pragma comment(lib, "advapi32.lib") Program is working.
and
BOOL WINAPI OpenThreadToken(
__in HANDLE ThreadHandle,
__in DWORD DesiredAccess,
__in BOOL OpenAsSelf,
__out PHANDLE TokenHandle
);
what does parameter in OpenThreadToken (OpenAsSelf) means.
Please give some valuable suggestions.
Regards,
Vishal

Answer to first question: If the program is working without it, you have your answer.
Answer to second question: From MSDN:
OpenAsSelf [in] -
TRUE if the access check is to be made against the process-level security context.
FALSE if the access check is to be made against the current security context of the thread calling the OpenThreadToken function.
The OpenAsSelf parameter allows the caller of this function to open the access token of a specified thread when the caller is impersonating a token at SecurityIdentification level. Without this parameter, the calling thread cannot open the access token on the specified thread because it is impossible to open executive-level objects by using the SecurityIdentification impersonation level.

advapi32.lib is already linked in the linker. Found in the Project Settings ->Linker->Input->Additional Dependencies.
thanks. for your reply.

Hello, I need a source code simple windows explorer or file manager on c++ using functions winapi,thank you very much

Try Google[^].

and on this site is no source?

I don't know of any which of course does not mean they don't exist. Again, i can say, try searching with keywords like "file manager windows" or such around the forums and articles here. Many times google also has links to CodeProject with useful stuff. I hope you will find what you are looking for.

There is plenty, but you have to find it yourself.

What have you tried? Search in google and code project yourself. No-one will do homework for you.

Hi guys(and girls  ),
i want to copy the data of a function, with the whole data, i mean, the whole function and execute it on the target memory. How do i realize it?
Is there a possibility to determine when the function ends? Is it possible to copy the function into the heap and execute it there ? Or has it have to be the Stack ?
I tried to look into it with a Debugger and so on, but couldnt get any information regarding the matter.
thanks in advance for every answer =)
btw. i use C (gcc)

Are you working on windows?
[EDIT] If you had said yes then i would have suggested the same thing as barneyman did "below".  [/EDIT]

have a look at the VirtualAlloc and VirtualProtect winAPI functions - you'll need to grant PAGE_EXEC rights (I assume you're doing this in Windows)
You'll know when the code finishes because the function will return back to you
|
|
|
|
|
thanks, but i am working under ubuntu.
And yes the function will return, but i have to copy it beforehand, before i execute it.
|
|
|
|
|
Try googling for linux equivalents of those methods. I hit mmap[^] for example, maybe that can do what you wish for VirtualAlloc, for VirtualProtect mprotect[^] might work.
