Re: How do I load another programs Icon?

Have you considered ExtractIcon()?

Grr - I knew there had to be a simple function.

not LoadIcon, not ExtractResource...

I started thinking about LoadLibrary, FindResource etc...

Then I sae you'd already replied with the perfect answer.

Sometimes "we" can be too clever for our own good.

CInternetSession Problem

Hi,

I am writing an appliction which downloads MJPEG stream from IP camera. My application supports many IP cameras at a time. So i need to download several URL at a time from single instance. But the problem is when I add my fifth camera my application gets hanged. So is there any limit on how many URLs we can open using CInternetSession's OpenURL method? From my application I am able to open upto 4 URLs for one instance. For fifth URL my application give "timeout" exception.

Code:

CStdioFile* m_pFile[5];
CInternetSession m_inetSession[5];

for(int iIndex = 0; iIndex < 5; ++iIndex)
{
m_pFile[iIndex] = m_inetSession[iIndex].OpenURL (cstrUrl, 1, INTERNET_FLAG_TRANSFER_BINARY | INTERNET_FLAG_RELOAD);
.
.
}

Thanks in Advance.

Since CInternetSession class is a wrapper around InternetOpenUrl(), you could temporarily change your code to use InternetOpenUrl() instead. When/if it fails, you can call GetLastError() to find out why.

GetLastError() returns error code 12002.

From the docs:

ERROR_INTERNET_TIMEOUT
12002
The request has timed out.

Are you sure the URL is valid?

Struct or class?

Hello everyone,

Multiplies is a struct, why MSDN said it is a class?

thanks in advance,

Because in C++ a struct and a class are quite similar. The difference is that structs give, by default, public public access to their members, while classes do the opposite (private access, by default, to their members).

learn your school lessons. in C++, a struct is a class (the only difference is that is defaults is members as public instead of private).

C++ recommands that use class only for its spirit.
struct in C++ is for compatibility with C.
However you can think class as a mentally concept, as a more common concpet, so either can be called a class as you like.

I want to custom a Browseinfo window.
For original Browseinfo only gets the address information, I also want to know which form user choose(xsl,xml,txt,ect) now.
So, I want to add a ComboBox on the Browseinfo window.

I tried, but always encountered error when I calculate the ComboBox's location.

Does anyone have a relative Demo ? (a simple one is better Poke tongue | ;-P

)
And welcome any idea.
Thanks a lot!

When i call the CDialog::OnOK(); function I get error :
C:\Documents and Settings\Administrator\Desktop\new_pdf_latest\pdf_latest\itagane_latest\itagane_latest\itagane\CTools\daishi.cpp(116) : error C2039: 'OnOK' : is not a member of 'CDialog'

How can I solve this error?

One possibility is deriving your dialog from CDialog

The other one is establishing it by yourself

//in header
//{{AFX_MSG(CDaishi)
virtual void OnOK();

//in cpp
void CDaishi::OnOK()
{
//do whatever you need
}

Forget about it. I didn't pay attention, you are not in MFC.

And how can he derive his CDialog from MFC's CDialog?

/in header
//{{AFX_MSG(CDaishi)
void OnOK();

//in cpp
void CDaishi::OnOK()
{
//do whatever you need
CDialog::OnOk();
}

Remove the virtual keyword in the header.it will Work
