IE automation [modified] - C / C++ / MFC Discussion Boards

hai all,
in vc++ 6.0, for a dialog based application, is it possible to hide its instance on task bar?
please let me know any clues on how to achieve this.
thanks in advance.

Look into WS_EX_APPWINDOW

How to load dynamically latitude, longitude values from my Exe to Search box (maps.google.com) browser.

Thanking all of you in Advance.

A BHO, perhaps. You might also check to see if the browser has a COM (i.e., automation) interface.

I'm still new to learning C++ (learned some of C# first) and having a hard time knowing what the preferred way to handle this situation is.

I have a class that has a constructor that does some initialization work. If this initialization fails, I want to inform the program that this is not a valid object to use. I created my constructor to throw an exception as that is really the only way that I know how (since constructors can't return values).

Now, in my program I am trying to create an object of my class so I put a try/catch block around it. This worked great until I realized that no code outside of the try/catch block would be able to use that object because it is out of scope.

It appears that there is no good way to use global variables that has a constructor that throws an exception. So what is the normal procedure for this type of situation. Do you normally create a pointer to the object so that you can use the new keyword to create the object? If so, is there a way to prevent someone from creating an object and not a point to your class?

Yes, that's what I'd do.

Make the constructors private and add a static method that returns a newly allocated object:

class C
{
public:
   static C* MakeNewC() { return new C; }
private:
   C()
   {
   }
};

int main()
{
   C c; // This won't compile
   C* pC = C::MakeNewC(); // This will compile
}

HTH!!!

I'm trying to automate IE. That piece of code works fine on my VC++ desktop computer with vista and IE8. The problem is it's not working on my laptop (vista + IE7). There is no error message. According to the messageboxes, the code stops when trying to get the READYSTATE statement. I mean I got the first messagebox ("navigation ...") but not the second one ("readystate ..."). Plus the browser doesn't close as it is supposed to do.

I don't know if it's related but I compiled the project using the /MT command and I didn't install the Visual C++ 2008 Redistributable Package (x86) on the laptop. This is because I want to run this code as a single exe.

Can please someone help me to understand wht is going on ?

Here is my code :

#include "stdafx.h"
#include "Exdisp.h"
#include "mshtml.h"
#include "windows.h"
#include "winerror.h"



int _tmain(int argc, _TCHAR* argv[])
{
if (SUCCEEDED(OleInitialize(NULL)))
  {
    IWebBrowser2*    pBrowser2;
	IHTMLDocument2*  Doc;
	IDispatch* pHtmlDispatch;
	READYSTATE rState;
	DWebBrowserEvents2* pEvents;
	HRESULT hr;

   CoCreateInstance(CLSID_InternetExplorer, NULL, CLSCTX_LOCAL_SERVER, 
                       IID_IWebBrowser2, (void**)&pBrowser2);
   if (pBrowser2)
     {
			
		VARIANT vEmpty;
		VariantInit(&vEmpty);

		BSTR bstrURL = SysAllocString(L"http://www.google.com");

		hr = pBrowser2->Navigate(bstrURL, &vEmpty, &vEmpty, &vEmpty, &vEmpty);
		if (SUCCEEDED(hr))
        {
			MessageBox(NULL, TEXT("Navigation successful"),TEXT("Status"),MB_OK);
			pBrowser2->put_Visible(VARIANT_TRUE);
			
		   
			
			do
			{
				hr = pBrowser2->get_ReadyState(&rState);
			}while(hr == S_OK && rState != READYSTATE_COMPLETE);
			
			MessageBox(NULL, TEXT("ReadyState Complete"),TEXT("Status"),MB_OK);
         }
      
       SysFreeString(bstrURL);


       hr = pBrowser2->get_Document(&pHtmlDispatch);
	    if (SUCCEEDED(hr) && (pHtmlDispatch != NULL)) 
         {
			MessageBox(NULL, TEXT("Dispatch obtained"),TEXT("Status"),MB_OK);
			hr = pHtmlDispatch->QueryInterface(IID_IHTMLDocument2, (void**)&Doc);
			if (SUCCEEDED (hr) && (Doc != NULL))
			{
				MessageBox(NULL, TEXT("Document obtained"),TEXT("Status"),MB_OK);
				




				Doc->Release();
			}
			else
			{
				return hr;
			}
			pHtmlDispatch->Release();
        }
		else
		{
			return hr;
		}


		pBrowser2->Quit();
		pBrowser2->Release();
     }

   OleUninitialize();
  }

	return 0;
}

I do wonder if it's something to do with not having an active windows message loop (which COM uses for marshalling calls with single threaded apartments, IIRC) - I mean, you do while the message box is active, but not afterwards - maybe the laptop's slower at getting to the readystate=complete? After all, IE7 is slow as a dog compared to real browsers, even IE8!

So - might be worth adding message dispatch in the do/while loops?

Hi,

I typed in the following code and found it to compile and run ok (using VS 2003).

<br />
#include < iostream ><br />
using namespace std;<br />
   <br />
template <class T , class U> void  swapa(T & a, U & b)<br />
{<br />
	cout << a << " " << b;<br />
}<br />
 <br />
int main()<br />
{   <br />
<br />
   int x = 3;<br />
   const double y =5.234;<br />
   swapa < int , const  /* should'nt the "double" be explicitly stated here? */  > (x, y);<br />
     <br />
   return 0;<br />
}<br />

I am surprised of this as I did not declare the type explicitly in the invocation of swapa() where the comment is. Can someone pls explain?

Many thanks!

Isn't it

template void <class T, class U> void swapa(T & a, U & b)

?

I' m a learner in visual c++ developing environment.
Here's m problem . . .
------------------------>

I am using a tutorial to make a simple program to send messages to another program using CAsyncSocket class.
I wrote complete application's code as given in the example(in visual studio 6 IDE). I compiled the application and the program run successfully without any errors. Smile | :)

Then I compiled same program in visual studio 2008(Professional Edition) and It also run as expected. Smile | :)

But When I wrote the same program from scratch in visual studio 2008 it showed some misbehavior while receiving data. Confused | :confused:

The main problem with the code given below is that it sends data(as shown in the code below) but on the receiving application only first byte is received(When project is written from scratch in VS 2008 Pro).
But if application is written in Visual studio 6 then there is no such problem.
I' m totally confused what to do? where is the problem actually residing? Please send any suggestion.

-->I have VC++ 2008 FeaturePack installed.
-->Create an MFC Application named "Sockets" and link MFC as statically.
-->then use files below to make the application.

I love work. It gives me something to do between weekends.

My guess would be that the 'from scratch in VS2008' version uses Unicode, the 'upgraded from VS6' one uses ASCII. I can see various places where you are (incorrectly) assuming ASCII, but the killer is in CSocketsDlg::OnReceive. Where you read a number of bytes and then append to a CString. The string you've received will have '\0' characters in it, because it's a wchar_t string that you've interpreted as char, so when you append it to a CString, the rlevant method will use strlen to find the string length, see the zero byte after the first character and say 'Aha, that's the end of the string!' - but not where you a) wanted, or b) expected.

So - fix the ASCII assumptions, man!!!! Or turn off Unicode

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Here's some data sent and received b/w both applications and their versions->

I hope this will give u a clear understanding about my BUG.
If u compile these applications then u should get these results.

I already understand what your bug is, well enough that I told you how to fix it - either turn off Unicode in your app developed from scratch with VS2008, or make your usage of Unicode/ASCII strings consistent.

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

how to turnoff Unicode in current project in VS 2008 Pro

Manmohan Bishnoi

Select the project in solution explorer, right-click on it and select Properties from the context menu. Now go to the Configuration Properties->General property page and set the Character Set property to 'Use Multi-Byte Character Set'

Debug version is working ok but not having xp common controls look.
Release version not working ok but having xp common controls manifest.

Manmohan Bishnoi

Did you change the property for Debug AND Release configurations - the properties are (unfortunately, in many ways) set separately.

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

And the manifest file...ummm - is the project property Configuration Properties->Linker->Manifest File->Generate Manifest set to Yes in all cases?

Although it may be that XP themes need Unicode.

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

done as u told me to do. But no use.
Anyway atleast debug version got somewhat debugged.

Manmohan Bishnoi

Hi.
I'm stuck with the same problem. Whenever my program receives data from any tcp/ip server, it displays it correctly, but when it sends data back to the server, the latter receives only the first character. Turning off Unicode is not an option, becouse the tcp/ip communication is only a small part of the project, and this change generates lots of other errors. I'm also using the tutorial from David Chapman's "Teach yourself Visual C++ 6...", and Visual Studio 2k8, so my code is almost exactly the same as monu_biosman's.
I'd like to ask Stuart, or anyone else for that matter, what exactly I need to change to make it work. I already made lots of tests, but none seem to work.

//original code: (m_strMessage is a CString)
      iLen = m_strMessage.GetLength();
      iSent = m_sConnectSocket.Send(LPCTSTR(m_strMessage), iLen); 

//I've been changing the iLen, and it's not the problem. Then I've tried:
      iSent = m_sConnectSocket.Send("blablabla", 9);

//and it works!!!. But then I've tried the seemingly same code:
      CString buffer = "blablabla";
      iSent = m_sConnectSocket.Send(buffer, 9);

//and it also sends only one character (b to be exact). So the problem can propably be solved by adding //some type of conversion. So far i've tried this:
      char[1024] buffer;
      wsprintf(buffer,"%s",m_strMessage);
      iSent = m_sConnectSocket.Send(m_strMessage, 1024);
//and.. it does not compile, C2664 error, "'wsprintfW' : cannot convert parameter 1 from 'char [1024]' to 'LPWSTR'"

I'm running out of ideas, or maybe I'm a retard i don't know. Any help would be greatly appreciated. Thanks in advance.

SquiZZlo

Ok, I've found the answer to my problem on another forum:

iLen = m_strMessage.GetLength();
CStringA ansiString(m_strMessage);//one freaking conversion!
iSent = m_sConnectSocket.Send(ansiString, iLen);

Works prefectly! Big Grin | :-D
