It's a new functions only available on NT machines. In order for the compiler to see the function, you have to define WINVER to 0x500.

You have to include < winspool.h > in the cpp-file where you use it, you have to link against winspool.lib, and you have to read MSDN! Its all in there!
My opinions may have changed, but not the fact that I am right.

put the line:
#define WINVER 0x0500
in you stdafx.h before any #include's

You probably need to get the latest PlatformSDK from Microsoft.

Nowadays the GUIs created with Flash MX are well received.
I love the visual effects that are not easy to achieve
just with some knowledge of Windows API and MFC.
I am some conversant with Windows API and MFC, so want to
go on using them to implement many parts of programs, while
creating GUI with Flash.
How to interact with Flash "controls" from within MFC? To be more specific,
if I press a button in the Flash I like to make a MFC dialog
box such as AfxMessageBox("Hello") pop up. Likewise, if I am to put
a string in an edit box in the Flash?
I haven't set about learning Flash yet but hope
some advice posted here could guide me through a new
programming experience.

You can have links in html (flash) that send actions to your application.
For example you can have a html file with the following links:
Minimise.
Beep.
Unknown request.
You have to override the OnAppCmd from CViewHtml or CHtmlCtrl and do something like this:
void CHtmlCtrl::OnAppCmd(LPCTSTR lpszWhere)
{
if( _tcscmp( _T("Minimise"), lpszWhere )==0 )
{
AfxGetMainWnd()->ShowWindow( SW_MINIMIZE );
}
else if( _tcscmp( _T("Beep"), lpszWhere )==0 )
{
MessageBeep( MB_ICONASTERISK );
}
else
{
MessageBox( lpszWhere, _T("Unexpected Command"), MB_ICONQUESTION );
}
}
The OnAppCmd is called by OnBeforeNavigate2 when a link starts with "app:".
So you can put a link on your button that will be interpreted by your application.

I would like to share my knowledge on doc based and dialog based archtectures (many not be new - But can be interesting when there are more comments ....)
My understanding on the above is document based applications are maily for say, word/paint brush kind of applications and dialog based is generally used for say, take an input (port configure info) process them and show the results on the dialog box controls...
any comments?
|
|
|
|
|
I would say based on my experience writing and using many apps that your comments on what dialog-based app is used for is wrong.
Dialog apps can be used for anything MDI or SDI app is used for. The choice of UI is up to author, but decision to use dialog in no way limits what functionality is provided by app.
Best wishes,
Hans

But then you would have to do a lot of things yourself for which the Framework takes care with MDI/SDI.
But if you would have to tweak MFC anyway, you are probably better off using dialog based GUI. Anyway, you can do all stuff that the MFC doc/view provides also by hand.
My opinions may have changed, but not the fact that I am right.

Thaks Hans,
Yes I do agree with that... But in view of what visual studions AppWizard generates (I hadnt mentioned it earlier), We must have decided before hand, what kind of application we are goind to build (SDI/MDI/Dlg)...

Hi
Let's say i change 3 words of an rtf file
When i compile the .hlp file with Micr. Help Workshop i get the following error:
HC4002: Warning:
The RTF file c:\docume~1\jbrg\mydocu~1\testin~1\helpfi~1\hlp\.\showstring.rtf is corrupted at offset 309.
This only happens when i change the file and save it.
If i recompile the first unedited file, it compiles good without 'corrupted ..'. When i change a word in the file, i get that error. Anyone any ideas?
Does anyone know what the problem might be?
Greetings
Jens

Hello,
I have an MDI application and
I’m trying to create child window(s),
that could be move outside the main application area (CMDIFrameWnd).
Is it possible to do sth. like this?
Thanx for the help,

Not with MDI. The MDI child windows are clipped within the MDI client.

I have no problem with this code... no error, no warning...
What's your error message?
Hello World!!!

:(Dear Raphael,
I declared it , inside file header of generic class with other structures.
if i declare the struct inside file .cpp i not have the problem . Why ???
thank's
|

Wherever you use your struct, it must be known.
A header file with this definition that is included in any cpp where you use the struct would nornmaly suffice.
But when (in a third header) you make a variable of (instantiate) the struct, the compiler also needs to know it to reserve the right amount of space.
So maybe you need to include the header defining your struct there also.
Hope this helps.
My opinions may have changed, but not the fact that I am right.

MYSTRUCT mystruct[] =
{
{1,"xxxxxxxxx"},
{2,"YYYYYYYYY"},
{3,"CCCCCCCCC"}
};
Trust in the code Luke. Yea right!

Inside your structure you have a pointer and you need to allocate memory to use it properly.
for( i = 0; i < 3; i++)
{
mystruct[i].y = new char[ length ];
}
The program might compile and give you no errors but when you don't expect it, it will crash.
