Additional Toolbar in WinCE

21-May-01 6:32

Disclaimer: I'm in the middle of very long compile - can't really test this, so treat the solution with care Smile | :)

On a frame window level, override the OnCmdMsg virtual function. Implementation should check for ID_PRINT* messages and forward them directly to 'printing' view by calling its OnCmdMsg. Otherwise, call CFrameWnd::OnCmdMsg.

You can't play with OnCmdMsg on document level - this will cause recursion, stack overflow and crash.

Hope this helps Smile | :)

I am creating an text editor application for a Windows CE device HPC Jornada handheld. I already have the main toolbar at the top of the dialog but I want to add an aditional toolbar at the bottom. I have created the toolbar using MFC and include all the buttons in the class wizard. I cannot get the toolbar to display though - any ideas/help would be greatly appreciated.

Confused | :confused:

Maybe, if you post some of the code you use to create the toolbar...

I don't know with MFC, but if you use plain API calls, the toolbar works quite different on CE and Win32...

BTW, isn't it a CommandBar you are using???

Fixed Size Formview ???

Can anyone tell me how to disable the maximize/minimizebox and the ability to resize from a CFormview object? In other words make the formview look like a regular dialog. I tried to set the settings in my resource to fixed size but the formview still allows me to resize...

Your should override CChildFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI) method. Within this method
set the lpMMI->ptMaxTrackSize and lpMMI->ptMaxTrackSize to size your want your form to be.

Can't I disable or hide the minimize or maximize boxes ??? I tried to remove it from the style in the PreCreateWindow method, but they still appear...

Try it again Wink | ;)

BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs)
{
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs

cs.style &= ~(WS_MINIMIZEBOX | WS_MAXIMIZEBOX);

if( !CMDIChildWnd::PreCreateWindow(cs) )
return FALSE;

return TRUE;
}

The code above works - the frame window appeared without MAXIMIZE & MINIMIZE buttons.

Best regards,

How can I make fucntion pointers to member functions of a class??? The function pointer is ALSO a member of the same class, but I get this error:
//header file
void (*funcPtr1) ();
void chooseCharacter();
//cpp
funcPtr1 = chooseCharacter;

the error:
error C2440: '=' : cannot convert from 'void (__thiscall StoryLine::*)(void)' to 'void (__cdecl *)(void)'

please it's urgent!!!

Sorry for the first post - it's incomplete.

You should to change declaration of funcPtr1 as well to indicate that you need pointer to member:

void (StoryLine::*funcPtr1) ();

hi all,

how can i change a control´s version number. for example increment it by one with each compilation. Right now i always get 1,0,0,1 and if i want to change a cab file - this control is not being installed on some other remote machine (since version number does not change, i guess )

I tried to change
_wVerMajor
_wVerMinor

but it did not change anything

thanks for any help

Hi All,
I have a interesting query.I have a ATL Service.In this service I want to create a Database using DAO .This Database created need to be accessed by ADO. I was able to create the Database successfully using DAO .
I included "afxdao.h" file for this.
Now to access the Database using ADO ,I had to import
" msado15.dll ".After importing this Dll when the server is executed I am getting a error that "WINDOWS.H" is already included.When I remove this dll this error does not come but the ado objects could not be used to access the Database.

I want to use DAO and ADO both in same program.If it is possible,how can I rectify this problem ?

Thanx in advance for the help .

Regards,

Very simple questions ...

I recently start with Visual C++ and i made a new project from template "Win32 Console application" "a hello world application", now I would change the colors of the text, the cursor position and clear the screen, with other compilers I made this with "textcolor","gotoxy" and "clrscr()" respectively but with VC++ I don't know how can I do it.

Thanks

First, you get need handle to the console -

HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

Check for INVALID_HANDLE_VALUE, but note that this handle can be 0.

A gotoxy can be written like this, using the SetConsoleCursorPosition call:

void GotoXY(SHORT x, SHORT y)
{
        COORD	pos;
        pos.X = x;
        pos.Y = y;
        SetConsoleCursorPosition(hConsole, pos);
}

To change colors, check out the SetConsoleTextAttribute console API function:

// lo-white on blue...
SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_GREEN |  
                         FOREGROUND_BLUE | BACKGROUND_BLUE);

Clearing the screen is explained in the MSDN article "HOWTO: Performing Clear Screen (CLS) in a Console Application".

I've noticed diffeences in how colors are handled in win9x vs NT/2000. Backgrounds may 'bleed' to the next line in win9x. Also, console apps behave a little differently when closed under the two OSs.

Search the MSDN for "Console functions". Lots of neat stuff you can do. Smile | :)

I enumerate the encoders registered on my computer(such as:Cinepak Codec by Radius, MJPEG Compressor,DivXMPEG-4 Fast-Motion...).Then how can I select one of them (Such as DivXFast-Motion) to compress the timeline using DirectShow filters?
Note:
These encoder have the same CLSID(CLSID_AVICo),only FccHandler and FridenlyName are different.How to select one of them?
Thanks!
