Hi all,

I want to pass a CString parameter through ShellExecute() api to my exe..

I am doing this using this code:-

CString CurrentPath = _T("C:\\test\\test.ini");
ShellExecute(NULL,_T("open"),CurrentPath,NULL,NULL,SW_SHOW);

My problem is i don't know how to access this parameter in my exe.

Can anybody tell me how to do so??

Thanks in advance

I see no exe in the above code.

sorry i posted wrong code

CString CurrentPath = _T("C:\\test.exe");
CString para = _T("c:\\test.ini");
ShellExecute(NULL,_T("open"),CurrentPath,para ,NULL,SW_SHOW);

what i want is i want to access para value in my test.exe code

Hi,

it depends on language and compiler.
Most often you can get the command line as a string and/or the command line parts as a
string array; look for:
- the (optional) arguments of your main or WinMain function;
- a library function such as GetCommandLine.

BTW: When an array is returned, most likely the first element is the path of the EXE itself.

Hi there,

I am currently now beginning to learn C++. As i am new i will keep editing the program and do compilation for quite a number of times. It seems that every time i do it for more than 5 to 6 times the program will start to hang and i cannot compile nor stopping the compilation. Kindly assist me on this matter, really appreciate it.

Regards

Do you mean Visual Studio IDE hangs? Then you probably have to install it again.

Hi,

The Subject explains my prob, i wanna to put my formview in the middle of my screen

I use the SetWindowPos as below:

<br />
	CRect Rect;<br />
    GetParentFrame()->GetWindowRect(&Rect);<br />
    GetParentFrame()->SetWindowPos( NULL,0,0,900 ,200 ,SWP_NOMOVE | SWP_NOZORDER);  <br />
    SIZE size;<br />
    size.cx=Rect.Width()/2;<br />
    size.cy=Rect.Height()/2;<br />
    SetScaleToFitSize(size); <br />

in other way i wanna change the x, and the y ( i don't matter about the cx & cy) coz they depend on other vars but what ever the cx & cy values are, i wanna havr the form in the center of my screen.

PS: may be i should use some funct like GetWindHeight() or sth else Roll eyes | :rolleyes:

OnNewWindow2 multithread

ftbk11-Apr-08 23:29

11-Apr-08 23:29

Is it safe to use OnNewWindow2 on multithread ?
For example, one thread's WebBrowser fire NewWindow2 and let another
thread's application take the Dispatch pointer ?
AthreadWebBrowser::OnNewWindow2(LPDISPATCH* ppDisp, BOOL* Cancel)
{
Cancel = FALSE;
HRESULT hr;
CoInitializeEx(NULL,COINIT_MULTITHREADED);
LPSTREAM pStream = NULL;
hr = ::CoMarshalInterThreadInterfaceInStream(IID_IDispatch,*ppDisp,&pStream);
if(hr != S_OK)
{
AfxMessageBox("couldn't get interface");
}
}
but it's failer

which design is better to wrap another class instance

Hello everyone,

Some people doubt that the design below is inferior compared to design which makes f, either Foo* or Foo&. The reason is below design will waste memory space and degrade performance by creating a new instance.

I think it depends. If we really needs to wrap a new instance, I think the following design is fine. If we needs to refers to an existing instance, this design is inferior because it will waste memory space and degrade performance by creating a new instance and destroy the original one.

class Foo;

class Goo
{
    Foo f; // change to Foo* pf or Foo& rf is always better?
}

thanks in advance,
George

You are missing an important point here. Everything is not related to performances only. In this case, it will make a huge difference if you are using a new class instance instead of a reference or a pointer to an existing instance: this will be a copy of the original object, which means that all the modifications you do on this copy won't affect the original object (which is the case when you use a reference or a pointer).

You have to think about that before taking into account performances issues, because it has a major impact on the design of your program.

Thanks Cedric,

You mean none of the 3 designs are always good or bad, it depends on requirement, right?

Indeed:
- You cannot wrap a new istance by means of reference.
- Dynamically allocation of new instance is usually a bad idea (you may forget cleanup).

What means "wrap a new istance by means of reference"? Could you give more description or show some pseudo code please?

It's simple: reference variable must alway be assigned. Hence you need to pass an object to the class,
that is, you're making a reference to an existing object.

We have historically had so much trouble with 'lost' pointers, that we embed 'cookies' to our other objects within others, instead of the pointers themselves. If you have a pointer to an object, it is hard to tell if the object is still around, unless you have the address of a smart pointer that won't let object delete until all references to the object are gone. If you use cookies, you can ask a lookup table to translate cookie for you, and if that is gone, then object is gone too.
