hi, i've been programming in WinAPI for several years now, and somtimes I encounter MFC conversations with my mates, I ignored it coz I think I don't need it. However, I'm curious as if due to complexity I'm always encoutering with WinAPI, I sometimes wished I knew MFC, but someone told me that MFC s bloated. Most of my projects are very tight in terms of size, so I'm confused, they say that MFC is better, but bloated? while ofcourse WinAPI is really powerful (for me) however the downside is difficulties of implementing just a small function for a lot of codes. I thought MFC makes codes smaller? but why or how come that it is bloated? it is C++ anyway, right?

The main advantage of MFC over WinAPI is that it's more productive, probably easier to see what's going on. But yes it may well be bloated for your requirements. However, there are alternatives (none of which I've used):
1. Qt and wxWindows which are cross-platform toolkits.
2. Windows Template Library (WTL). This was an unofficial release from Microsoft but is now open source. There are tutorials on this web site and it is highly rated, and it is I believe more elegant and less bloated than the ageing MFC.

I think you also need to define your 'bloat to productivity' limits.
I mean, suppose I write a dialog app in pure WIN32 API and it takes me two weeks and it is 69K in size, and then I write a dialog app in MFC in two or three days and it is 120K in size, am I really worried it is 'twice as big' as the straight WIN32 application? Considering I am done in a fraction of the time and working on the next project already?
What I don't recall seeing is what MAKES an MFC app so 'bloated'? Linking in COM? ActiveX? Database? If you just have a few windows on the screen and a bit of data processing to go along with it, it is not 'horrible'. What might also make the MFC application seem bloated is all the DLL and other WIN32 API that get linked in to a 'generic' MFC program. It seems the memory footprint of an MFC app tends to be larger than a similar WIN32 application. If it were somehow more granular, the 'bloat factor' could probably be reduced. I think the WTL allows more granularity like this than the MFC libraries do.
If you are COMPELTELY hardcore, you could rebuild a special MFC library that did not have the extra stuff in it you did not need, and then link it into your program, you might end up with something smaller, but then consider the time involved in doing that conversion.

morning
I´d like to know how I can pass arrays as parameters to functions in VC++. (I´m a beginner to VC++, and have all the methods inside one class)
When I try, I get an error message saying that the array must specify __gc or __nogc. However, trying to declare the funtion like this:
bool function(__gc char array[]){return true;}
I get a msg saying that __gc can only be applied to an array !!
How should I declare the array in the firs place, and how should it be declared in the parameter list?

Something like:
void function( char arr[] )
{
}
void main( void )
{
char arr[5] = {'h', 'e', 'l', 'l', 'o'};
function(arr);
}

Yes, as long as you have correctly included the MFC header and library files.

MFC header and library files

#include "windows.h"
#include "afx.h"
i try above header files.
i can not access CString.
how can i do?

I would suggest using AppWizard to create an MFC DLL rather than trying to retrofit your DLL to use MFC.

How to perform switch case in MFC (Not in dialog form)????
|
|
|
|
|
i'm quite sure you are not familiar with C++.
switch statements are C++ statements, so, any libraries like MLC (Microsoft), OWL (Borland) or any other understand switchs the same way...
the switch is a sort of if / else if /else statement...
so what is your question exactly ?

void CLawMaterialView::OnSelchangeType()
{
m_combo=(CComboBox *)GetDlgItem(IDC_TYPE);
m_eFruitVal = (eEnumeratedFruit)m_combo->GetCurSel();
switch (m_eFruitVal)
{
case 1:eRD;
m_combo1=(CComboBox *)GetDlgItem(IDC_COMBO2);
m_combo1->SetCurSel(0);
m_combo1->ResetContent();
m_combo1->AddString("White ceramic rod BA80");// I want it from databse NOT add one by one.
}
From above code, is it Add a new value after select the 1st combobox, BUT how to have a value in combobox is from database????
Plz advise!

The switch statement has nothing to do with MFC. It is a C construct.

I met a problem when writing a mfc regular dll. I want to export a funcion which create an object extending from CWnd. To my surprise, there occurs an error when calling the CWnd::createWindow()--return NULL as the window handle , however,it works very well if I directly add the class source in my project.
what should I do? Can anyone help me? Thanks very much!

You have two choices that work fairly well.
1. Call a function to display the window and all opeations are contained entirely within the DLL - this works well for dialogs, mostly.
2. Create the DLL as an MFC Extension DLL - the application loading the DLL should be an MFC application. Then you can export the entire class and use it within the application just fine.
Anything else is mixing the models MFC was designed for and will result in strange problems now and in the future.

Hi all,
I have three questions:
1-How to create a function like enumWindows?
2-How to use crystal report 10 in mfc?
3-How can I get the IP address when a client sends a
message to the server app?
regards.
Thanks.

Although less reliable, you could try using GetWindow() in a loop.

I believe they have an SDK. Have you looked into that?
