To opne word in your MFC application, first you have to create an application which supports Doc/View architecture. Then use COleDocument instead of usual CDocument class. Find out the help for COleDocument. If still u find it difficult, then send me a mail.

Either BS_AUTOCHECKBOX has not been specified in the style or you have code that is resetting the state.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

For non-MFC apps, look at the BM_GETCHECK and BM_SETCHECK messages.

MCSD question

6-May-02 5:24

I am planning to write the distributed C++ MCSD exam. Now I noticed that the books have all been discontinued (the MS Press books for it), but the exam isstill there and is not listed amonst exams that will be discontinued. Do you guys think that this exam will be around in the 6 months or so, or do you see it phase out within this year?

Switch views in SDI using MFC extention DLL Classes

Dave Loeser6-May-02 5:19

Hey guys, I've got one that I hope someone can help with:
Over on codeguru.com there is an article titled Separating the views of an MDI application into different DLLs

What I'm trying to do is create this same fucntionality within a SDI application. This app is workflow based and using an MDI just doesn't work for this type of application.

Here's some of what I have; In my DLL, I have exported one function:

extern "C" AFX_EXT_API UINT Init(CString *strLabel,CRuntimeClass **pRunTimeClass)
{
    new CDynLinkLibrary(View1DLL);
    *pRunTimeClass = RUNTIME_CLASS(CTestView);
    *strLabel = "View 1";		
    return 0;
}

In my test application I have a menu that will call this method when selected:

void CMainFrame::OnViewSwitchtodll() 
{
HINSTANCE hDLL;     
LPDLLFUNC lpfnDllFunc;   
UINT  uReturnVal;
CString strLabel;
CRuntimeClass* runtimeclass;
    
    hDLL = LoadLibrary("View1.dll");
    lpfnDllFunc = (LPDLLFUNC)::GetProcAddress(hDLL,"Init");
    if (!lpfnDllFunc)
    {
        FreeLibrary(hDLL);       
    }
    else
    {
	uReturnVal = lpfnDllFunc(&strLabel,&runtimeclass);
	CAADoc* pDoc = (CAADoc*)this->GetActiveDocument();
	pDoc->SwitchToView(runtimeclass);
    }
}

This loads up the DLL grabs a function pointer to the Init function exported in the DLL and then passes the runtimeclass to the SwitchToView() in my Document class (this was taken from an article on CodeProject).

When I step into SwitchToView the runtimeclass object appears to be fine... and I do not receive errors... but the mHwnd of the runtimeclass is ??? in the Variable inspector during debug.

I've come to the point where I need someone else to take a look at this - so any help?

Thanks in advance,

Dave "Dak Lozar" Loeser

Removing the scroll bars

6-May-02 5:09

I have two views in my application . One is rich edit view and one is edit view . They are split using the splitter windows . But the edit view by default has horizontal and vertical scroll bars associated with it. How to get rid them and make them auto vertical and horizontal scroll bars. I have overriden the precreatewindow function of edit view with the following code
cs.style &= (WS_CHILD | WS_VISIBLE );
cs.style &= ~(WS_HSCROLL);
cs.style &= ~(WS_VSCROLL);
cs.dwExStyle &= ~(WS_EX_RIGHTSCROLLBAR);
but to no avail . Can anyone suggest a solution Smile | :)

Getting a file from a website

Hi,

I'd like to know if anyone can give me some tips about how to programme in C++ a simple class for downloading a file from a web site, for example an image file. I want to incorporate this class into a project, so it does not need any flashy GUI or anything similar.

If possible, it would be good to avoid MFC classes because I need portability across windows/linux. My network programming is not up to scratch for this project that I have set myself. Frown | :-(

Can one use an HTML GET call? Do I have to basically write a ftp client?

Any hints, tips, links, or book references would be great! I've already had a look on the web, but most implementations seem to use MFC

Thanks,

James

Here you go:

bool downloadUrlToFile
  (CString strUrl,        // url
   CString strFilename)   // local file
{
  // Download the file if it doesn't exist
  HRESULT hResult = ::URLDownloadToFile (NULL, strUrl, strFilename, 0, NULL);
  return (hResult == S_OK);
}

::URLDownloadToFile requires Internet Explorer 3.0 or higher. I do not think that this is a portable solution.

You're right, but he'll probably have many other problems to worry about if he's running on a system with < IE3.0! Smile | :)

A portable solution will be using sockets, and using in the socket the http get command ...

Yes, that's exactly what you must use to download something from a web server.

Do I have to basically write a ftp client

No, you must write a http client. See the Winsock FAQ to see how to do socket communcations without MFC. Winsock 1 calls (the ones without WSA prefix) are easily portable to Linux (they are based on Unix socket functions).

with GetTcpTable & GetUdpTable you get the same result as netstat -an from the commandline.
On XP ,netstat have another flag -o which display the PId that associates with the Tcp/Udp port
how to accomplish that ? any ideas ? Rose | [Rose]

registering an ActiveX on pc?

Does anyone know how to register an ActiveX Control on another pc automatically without requesting the user to do it by him/herself?
is InstallShield capable of registering an ActiveX Control in setup.exe? but how? What should i do? do i need to write script for it?
When i send release of my app to my friend which includes an .ocx file they are compelled to register (many of them don't know how to do it as well by using Regsvr32.exe) it before starting the app.
Thanks for ur help..

Yes you need to execute the DLLRegisterServer function

#include <stdole.h> 

typedef HRESULT (STDAPICALLTYPE *CTLREGPROC)() ; // Requires stdole.h

HMODULE hModule = ::LoadLibrary(m_strPathName) ;
CTLREGPROC DLLRegisterServer =
      (CTLREGPROC)::GetProcAddress(hModule,"DllRegisterServer" ) ;
DLLRegisterServer() ;
::FreeLibrary(hModule) ;

Another problem with distrubuting my application is that Mr.Antollini.
i tried to use MFC ODBC classes to keep some user information. And whenever they need to search someone they would have easily connected a DSN and got the info. But i realized that that would need them to create an ODBC connection in their local but again it needs help (as in ActiveX..)
is there a way for making a ODBC Data Source connection by coding inside the app?
That would really solve one of my distrubuting problem Mr.Antollini
Thanks for ur help,

Yours respectfully...
