Hi! I m trying to view a MS Word *.Doc File in HTML view in VC++,by using Navigate2() function of CHtml view class. But the problem is that when the File viewed on HTML view all controls work,means i can right click on it,save this file by using F12 key ,open its help by pressing F1 key and all the other control. I just want to stop(disable) the working of these control. If i do EnableWindow(FALSE),it not only stop the working bt also stop the scrolling. I just want to stop the working of *.doc controls.

NiceNaiduCan somebody tell me the reason ,Why wizards generate enum IDD for dialogs?

The IDD enum of a dialog class contains the ID of dialog in the resource.

enum { IDD = IDD_MYDLG_DIALOG };

This IDD is passed in the constructor of your dialog to CDialog constructor.

CMyDlg::CMyDlg(CWnd* pParent /*=NULL*/)<br />
	: CDialog(CMyDlg::IDD, pParent)<br />
{<br />
}

You can simply get the ID of the dialog with a statement like CMyDlg::IDD

So when creating a dialog, we can use like

CMydlg dlg;<br />
dlg.Create( CMydlg::IDD, 0 )

Instead of

CMydlg dlg;<br />
Dlg.Create( IDD_MYDLG_DIALOG, 0 )

When MFC was initially developed a statement like the below one was not supported.

Class CMyDlg: public CDialog<br />
{<br />
  ....<br />
<br />
  public:<br />
  static const DWORD IDD = IDD_MYDLG_DIALOG;<br />
}

Also the trick of keeping an enum doesnt increase the memory size of object Smile | :)

CHTMLView and Compound File (IStorage)

Hi,

My problem is that I dont want to have my HTML files unprotected as simple files that everyone can view them.

So, Is there anyway to use with CHTMLView, HTML files that are stored in Compound File (IStorage) directly (without extracting them in a temp file)? Alternately is there any other method to use CHTMLView with HTMLs files that are protected in some way ?

I checked up the standard Windows Help *.CHM format but i think its too much complicated to use a such kind of solution.

Any ideas ?

Regards,

I want to store data of distinct datatype at runtime.

so how can i do this?

Is there any provision for this kind of support in MFC?

Why do you need to do such a thing ? Can you explain in details why this is needed ?
C++ is type safe, so you cannot just have any kind of data (or you could use a void pointer and cast it to what you need but this is ugly and will bring you a lot of problems).

I am recieving RTMP packet from flash.

It is for flash Object.
Now the data in object may get change runtime.
So how can i do same thing as like flash in MFC?

Is there any facility in MFC through which i can do this?

I still don't know what you are trying to do. So you receive a packet and it contains some data. How is this packet structured and how do you know which kind of data is contained in the packet ? What are the different data types that you can receive ?

When you need to use this data later, how will you use it ? What will you do with it and how will you identify what kind of data it is ?

You cannot just store any kind of data (well, not easily and it is in general far from being good practice), so what I'm trying to do is understand what you are trying to do in order to help. So, if you don't give enough information, I cannot help (and saying that you want to store any kind of data is not really usefull information). So, please be complete in your answer.

packet can contain array or object

If it is a objet then it can contain many values like int, double, char *, or another object, etc.

Thats not problem, my program can identify it at run time.

Now the problem is that how can i store these values so that i can access it again?

Is there any facility of assigning properties of object at runtime?

Any idea??

And how are you supposed to make the difference ? How do you know that the packet contains an object or an array ?

Manish_mnp wrote:

Same, how do you know which kind of data it is ? How is this information coded ? Qnd zhqt qre the other objects you can put in the packet ?

Manish_mnp wrote:

Yeah, but that's my problem. I cannot understand your problem until you explain it clearly. How can you identify what is contained in this damn packet ?

Manish_mnp wrote:

Ok, stop focusing on that and try to explain your problem as if it was impossible to do that. Then, we can discuss a possible solution. But honnestly, I hardly see a reason to use things like VARIANT because it will probably cause a lot of troubles.

Please, post some code snippet and the description of a typical packet. Without more information it is quite difficult to help you. And what are you supposed to do with what is contained in the packet ??

I am doing it through VARIANT

Now i am providing you a sample code here

<br />
	VARIANT var, var2;<br />
	var.dblVal = 2.0;// for demonstrating i am using it actualy it can be any type but i can know it<br />
	var.vt = VT_DECIMAL;<br />
<br />
	MyObject *myObj, *myObj2, *retObj; //Refernce to MyClass<br />
	myObj = new MyObject();<br />
	myObj2 = new MyObject();<br />
	myObj->setProperty(CString("DOUBLE"), var); //menber function which will set name and value.<br />
	var2.byref = myObj;<br />
	var2.vt = VT_PTR;<br />
<br />
	myObj2->setProperty(CString("OBJECT"), var2);<br />
	retObj = (MyObject *)myObj2->getProperty(CString("OBJECT")).byref;<br />
<br />
	CString st;<br />
	st.Format(CString("Val::%f"), retObj->getProperty(CString("DOUBLE")).dblVal);<br />
	AfxMessageBox(st);<br />
<br />

This code run perfactly but it is required that we have to provide perticular value(as .byres, .dblVal)

Is there any alternative to this code so that i can assigen all values by using only one Type(like obj.val = value)

Any Sugession ?

Have a look to MFC support for VARIANT datatype (or create a custom union by yourself).
