I am writing a web download installer and need to make it as small as possible. A lot of MFC is a black box to me so I am not sure which pieces I can hack out and still expect the program to behave as expected.
It is currently 210 KB and I only wrote a thousand or so lines of source code (including comments). There is only 1 window and it is a dialog-based app. It does use the file open common dialog box and afxinet.h
Thanks!

lets see... you could use an executable compressor like UPX for instance. Once you compile it run upx and compress your executable. get it here

sorry about the link... get it at www.upx.sourceforge.net

Shrinking the size of an MFC app in VC++ 7.x is difficult. In VC++ 6.0, you could get it down to about 160k but not much more than that.
Since it's dialog based, I'd consider just converting it to a standard windows app and taking the parts of afxinet.h that you need.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

If you want to keep it small then I think you should avoid using MFC.... write a simple application without them...
Did you compiled your app using the static MFC library version? You cannot hope that who will use your installed has already the MFC Dlls

I've looked all over this site, and googled it but I can't seem to get the count function to work. here's what I have:
int iCount = count(vecWords.begin(),vecWords.end(),sWord)
where sWord is a struct variable of the type the vector is holding. I even try to hard-code a 1 or any other type of variable in there and I keep getting the same error message:
error C2678: binary '==' : no operator found which takes a left-hand operand of type 'std::allocator<_Ty>::value_type' (or there is no acceptable conversion)
Can anyone help? Thanks!!
If it's broken, I probably did it

Have you defined the == operator for the type used as your vector element?
|
|
|
|
|
NO, I haven't. thanks!! but can I define an '==' for a struct?

Sure:
struct foo
{
int x;
bool operator== ( const foo& rhs ) const
{
return x == rhs.x;
}
};

Pinky, are you pondering what I'm pondering?
I think so Brain, but how will we fit the hamster inside the accordion?

thanks; I knew how to make the overloaded operator, I'm just not that familiar with structs.;)

in C++, structs are only classes whose default attribute is public.
of course you can, and better, you must ! (in your case, if you want to use this function)

hi,
I'm trying to write my own mp3 player using DShow, since this point I've been able to let mp3 start,pause,stop and get duration of song, but I don't know where to start from for showing how times goes forward, need I to use threads or DirectShow provides a simple callback function?
thanks a lot

When you start a playback, first check the length of the song. Then calculate time in a seperate thread timer that runs on a second's interval. This allows you to track the position in the song. The idea is just that you start the timer at the same time when you begin playing.
If you have the DirectX SDK fully installed on your machine, you also get the documentations. Open up the DirectX C++ documentation, and look in the Contents. Go to DirectShow -> DirectShow Tutorials -> Implementing a Seek Bar. There's a concrete example on how to create a seek bar. If you don't have the docs, you can see this topic in the MSDN by following this link.
Happy reading.

I'm writing a MFC MDI application, that has a dockable DialogBar containing a TreeCtrl to manage the application's project workspace. The problem is, I can't seem to initialize or otherwise interact with my tree control. I'm using VS 6.0 professional, I've designed the dialog in the resource editor and given it the id IDD_TREE_ORGANIZER. In addition I assigned the tree control a variable within the dialog class (m_tree). At first I tried to initialize the tree control in the dialog's OnCreate() function, but I just got a blank control. Then I read that the control should be initialized in a dialog's OnInitDialog function. I tried that as well, but again got a blank tree control (though the sample exersize I worked on did fine.. It was on a standard dialog though, and not a dockable dialog bar owned by the mainframe). Does anyone know of some sample code out there that shows how to create and interact with a tree control in a dockable dialog bar in an MFC MDI application that I can use for reference? I've been working on this for weeks and I'm pretty frustrated at this point

Consider OnInitUpdate().

Can someone guide me on how to add text to a word document using "Bookmarks" from a word template "file.dot". I started with the visual C++ code below but I get lost trying to follow the Microsoft Word Objects schema, I just don't know how to tie it in like the VB example.
Visual Basic example code ___________________________________________________
Set wrdApp = CreateObject("Word.Application")
wrdApp.Documents.Open("c:\file.dot")
wrApp.ActiveDocumnet.Bookmarks("String One").Range.Text = "Vb sample"
________end of VB example____________________________________________________
Visual C++ __________________
void SystemAlign::CreateDoc(void)
{
CApplication oApp;
CBookmarks oBooks;
Cbookmark oBook;
CDocuments oDocs;
Cdocument oDoc;
CRange oRange;
COleVariant vtOptional((long)DISP_E_PARAMNOTFOUND,VT_ERROR),
vtTrue((short)TRUE),
vtFalse((short)FALSE);
// Create an instance of Word
if (!oApp.CreateDispatch("Word.Application"))
{
AfxMessageBox("Word failed to start!");
return;
}
oDocs = oApp.get_Documents();
oDoc = oDocs.Open("c:\My Documents\file.dot", vtOptional);
oBooks = oApp.get_ActiveDocument();
//oApp.get_ActiveDocument()
}

I am writing dll programs to do some file conversions for scientific data. Is there any way for me to do a dyn. memory allocation with out having constants in between the brackets but rather have declared variables.
Here is what I have now..
const int X = 100;
const int Y = 50;
long (*data)[Y];
int x,y;
if (!(pix_data = new long[X][Y])) { printf("Error allocating memory...\n"); return 1; }
I cant figure out a way to have an integer in X and Y that is declared internally (in main()) rather than having 100 or 50. When I place integers, error comes up saying " expected constant expression". Thus, I need not specify 100 or 50 but it looks to other varibles to figure that out. I have looked everywhere..
Any help is appreciated.

change to
const int X = 100;
const int Y = 50;
long (*data)[Y];
int x,y;
if (!(pix_data = new long[X * Y])) { printf("Error allocating memory...\n"); return 1; }
for the memory allocation and it should be fine.

Thanks for the help. Rob..
Although, allocating isnt the issue I am having. Sorry, maybe I wasnt clear with my concern.I want to stay away from having to write:
const int X = 100;
const int Y = 50;
I have internal variables in main() that are assigned the values of 100 and 50. Thus, I would like to use them instead of having constants or define statements.. I want something like
int X = row_size;
int Y = column_size;
Ofcourse, that gives me an error saying "expected constant expression" at the line
long (*data)[Y];
This is because I am guessing c++ needs to know the size of the array before it starts compiling instead of looking in main().
I will have different files w/ different row_sizes and column_sizes so I cant have 100 or 50. So no input by the user specifying the # of rows or columns for each file I call is necessary.
Does that make any sense....

I am working on simple visual recognition program.
I have two bitmaps - background and background plus unknown object.
I can do convolution to filter out the unknown object, but I cannot figure out how to store the result for further processing.
So far I have same size bitmap with "empty" pixels.
Evetually I'll need to determine the shape of the object and I am looking for some kinda of trace algorithm to save this resulting image.
Thanks for your help Vaclav

I am trying to do this on my own at home, but have a serious need at work for the following DLL. I can do this in VB unfortunately WinRunner can not use VB DLL's since they are COM servers.
I wrote a simple dll that works but the this project is requires a message box.
I need a c++ dll that
a) I can launch a modalless message box with message passed.
b) keep on top
c) place on screen using x,y
d) close
Can anyone help me? I've never written a c++ dialog before.
thanks all
