About the only automated thing I know you can do with it is open and print. Other than that, I do not know of its having a COM interface.

You can use ShellExecute() with the open and print verbs.

You can call OnDraw() from outside the class, but you will need a pointer to the view object. The pointer can be like:

CMyView* pView;<br />
pView = ... the view object's pointer.<br />

Then you can use:

pView->RedrawWindow();<br />
pView->Invalidate();

this is this.

Where exactly outside of the view are you trying to access the view? Is it your own class? Is it from a thread? Is it from mainframe? Is it from the document?
If it is a separate class, then I could suggest:

class CMyClass<br />
{<br />
...<br />
public:<br />
CView* m_pView;<br />
};<br />
CMyClass Object;

Now you need to initialize the pointer to the proper value.
If you are calling it from the view then:
Object.m_pView = this;
etc.

this is this.

Hi, I have problem When executing my MFC application. It makes rebuild all and no problem. When I click on '!' Execute Program. It doesn't give any response. It doesn't give any error. The dialog does not appear. I am using Microsoft Visual Studio 6.0. What can be the problem?

You have not provided enough info like: is the code your own? What configuration is it (release/debug) ? Is it dialog-based, is it command-line based? etc.
There could be a dynamic library missing etc; the program tries to open non-existent files; Windows does not like your program because you are accessing un-allocated memory, and is shutting down your program without notice; You are allocating too much memory in static objects, which is not available;
It could be something else also.

this is this.

like SAS have choosen QT to develope cross-platfrom
application.
I have to develope application for embeded device,

Now and then we hear that this library is Better then MFC, that library is better then MFC... that might be true.. As they providing Cross Platform application development.. that MFC doesn't support..

So if you targeting cross development.. MFC is not suitable for that so there are no issues of Performance etc.

Or If you want to compare WxWidgets and QT ? Better ask Priyank Bolia.(Author of that article, which I referred in previous post).. he surly help you!.. or wait for other people to respond to your query

First of all wxWidgets is not MFC, nor it resembles to MFC. It had many ways of programming, like Message Maps as used in MFC for windows people and connect calls as used in Linux. wxWidgets is much better design than MFC, its very easy to use (like all event handler have a void return type, as compared to MFC where each function has its own way of defination). It is supported on WinCE also and support all the sockets, serial port,database,GUI. It use true native controls as compared to QT interpolation (simulation), so its fast. Its free, whereas QT is commercial. The support for wxWidgets is nice, as lots of open source application used wxWidgets rather than Qt (~3300$ per developer). Qt is copyright, you can't change the API for your personal modification, or bug fixes.

I just want to add that starting with wxWidgets is much easier now for VC++.NET 2003 developers, as there is a installer from upcase that install and compiles the wxWidgets automatically and installs the help file integration with Visual Studio. Also there is a class wizard also availble written by myself for wxWidgets on Visual Studio.NET

How to delete values and header from ListCtrl

snprani4-Dec-05 20:22

Hi
How to delete all column headings and values from CListCtrl. I am doing in this way.

int nColumnCount = m_ListCtrl.GetHeaderCtrl()->GetItemCount();
// Delete all of the columns.
m_ListCtrl.DeleteAllItems();
for (int i=0;i < nColumnCount;i++)
{
m_ListCtrl.DeleteColumn(i);
}

Is it correct or not. when i again displaying values in this listcontrol it is not deleting column names but deleting values. what should i do.

Thanks in advance.

Try :

int nColumnCount = m_ListCtrl.GetHeaderCtrl()->GetItemCount();
// Delete all of the columns.
m_ListCtrl.DeleteAllItems();
for (int i=0;i < nColumnCount;i++)
{
m_ListCtrl.DeleteColumn( 0 );
}

When you call DeleteColumn the header control is reindexing the columns everytime so always delete index 0 and you'll be ok.

int nColumnCount = m_ListCtrl.GetHeaderCtrl()->GetItemCount();
// Delete all of the columns.
m_ListCtrl.DeleteAllItems();
for (int i=0;i < nColumnCount;i++)
{
m_ListCtrl.DeleteColumn(0); // always delete first column
}

You delete all items with m_ListCtrl.DeleteAllItems() and only first column.
