It's very easy using Excel's COM interface (Automation). MSDN has several examples. This forum even has a few.

Bitmaps

Hi!
I want to design a GUI in which I need to have bitmap containing buttons, something like actual phone, where buttons pressed simulate the actual pressing of buttons. What kind of architecture will be best to achive it. should i go for a Windows application or something like dialog boxes or Document/View Architecture. Any suggestions---------------

My suggestion here is to go for Windows application & MFC.

MFC provides you a possibility of customizing your window creation by deriving a class from CWnd. This allows you, when necessary, to do custom-painting routines for your window. I developed a skinned application a while back, and it's main design structure was as follows:

1. Created the actual bitmap of the UI, and the bitmaps of buttons
2. Created a 1-bit (two color) mask from the UI bitmap, and used a customized version of Jean-Edouard Lachand-Robert's BitmapToRegion function to get a valid Windows HRgn
3. Placed this HRgn as the window's clipping region by a call to CWnd::SelectClipRgn.

This results in a window with non-rectangular outline and a custom-painted UI. Of course, you can alternatively use drawing functions to draw the outline of the phone yourself, but this is very tedious work in Windows. However, it allows for a more realistic-looking UI than the bitmapping does. When using a bitmap, the creation of realistic-looking buttons is next to impossible, as you probably need to create skins for them as well.

The workload of creating a custom UI is huge, but doable, and if done right, you'll get very nifty results as well. But my suggestion is to go with MFC. Not only can you have access to the whole Win32 API if required, but you can also enjoy the benefits of a "true" OOP programming model.

If you feel like attempting this approach, here is a link to the aforementioned routine. The link resides on the CodeGuru website (BitmapToRegion routine.[^])

The definition of impossible is strictly dependant
on what we think is possible.

A Windows application is not mutually exclusive with dialog boxes or document/view architecture.

You can indeed place a bitmap (with the necessary "buttons" on it) on a dialog box, and when it is clicked, determine where in the bitmap the mouse was when the click occurred. That will tell you the "button" that was clicked. You could also place multiple button controls on the dialog. This is easier than the bitmap route but probably not as appealing to the eye.

Thanks for your suggestion. I was wondering how on a bitmap, can we detect, where the user has clicked and perform the necessary action. say i have a phone gui and button on it. how will i know that user pressed a particular button.

David Crow11-Dec-03 8:59

I've never done it before, but I believe PtInRegion() is used. Each of the "buttons" on the bitmap has a region. The point at which the mouse is clicked can be checked against each region.

I think this is the function I was looking for. I am new to MFC so don't have much idea about its various classes. Also is there a way by which we find the coordinates of various points in the bitmap? Because most of functions of CRgn Class wants the coordinates of point in the bitmap.

Hi David,
I will like to check one more thing from you that is using dialog based application still good, when my gui consist of a single(one piece skin)with nothing else. the buttons are part of skin itself. say for example if u take a picture of phone u will see buttons on it. i want to simulate pressing of those buttons. so will dialog based application helps in it.

Yes, from what you've shown so far.

hello,i have tried to write a filemanager in c++,im using the WIN32_FIND_DATA struct,to obtain file information,this seems to work okay apart from one thing,it list's all the files and directorys in my c:\ drive,but for some reason it dosent show "program files" as a directory,does anyboy have any idia what might be causing this?

thank you for your time. Smile | :)

it dosent show it as anything,theese are the file artributes i got set: FILE_ATTRIBUTE_HIDDEN
FILE_ATTRIBUTE_COMPRESSED
FILE_ATTRIBUTE_SYSTEM
FILE_ATTRIBUTE_ENCRYPTED

do you know if i am missing anything there?

With the limited information you've provided, no.

I presume you have something akin to:

WIN32_FIND_DATA fd;
HANDLE hFind;
BOOL bContinue;
 
hFind = FindFirstFile(..., &fd);
if (INVALID_HANDLE_VALUE != hFind)
{
    do
    {
        // output fd.cFileName
        bContinue = FindNextFile(hFind, &fd);
    } while (FALSE != bContinue);
 
    FindClose(hFind);
}

yes very much like that here is what it looks like,

{
string filebuff;
WIN32_FIND_DATA FindFileData;
HANDLE hFind;

hFind=FindFirstFile(Directory.c_str(), &FindFileData);

do{

if( FindFileData.dwFileAttributes == FILE_ATTRIBUTE_DIRECTORY )
filebuff += "dir";
if( FindFileData.dwFileAttributes == FILE_ATTRIBUTE_HIDDEN )
filebuff += "Hidden";
if( FindFileData.dwFileAttributes == FILE_ATTRIBUTE_COMPRESSED )
filebuff += "Compressed";
if( FindFileData.dwFileAttributes == FILE_ATTRIBUTE_SYSTEM )
filebuff += "System";
if( FindFileData.dwFileAttributes == FILE_ATTRIBUTE_ENCRYPTED )
filebuff += "Encrypted";
else

filebuff +=("%*s", 30, FindFileData.cFileName);
filebuff += "\n" ;

}while ( FindNextFile(hFind, &FindFileData) );
//do something//
return 0;
}

i hope this gives a better understanding of what i might be doing wrong here,
my only thought was that i was missing out a file artribute that i didnt know about,there is no reason why "Program Files" isnt shown as a directory after all it is a directory isnt it,even if program files was hidden,it should stil show up as a directory too shouldnt it?
this code is what i took from my source,as im a n00b if ya spot any mistakes please lemmi know,thanks again 4 ya time.

Change your code to:

if ((FindFileData.dwFileAttributes & FILE_ATTRIBUTE_HIDDEN) == FILE_ATTRIBUTE_HIDDEN)
    filebuff += "";
if ((FindFileData.dwFileAttributes & FILE_ATTRIBUTE_COMPRESSED) == FILE_ATTRIBUTE_COMPRESSED)
    filebuff += "";
if ((FindFileData.dwFileAttributes & FILE_ATTRIBUTE_SYSTEM) == FILE_ATTRIBUTE_SYSTEM)
    filebuff += "";
if ((FindFileData.dwFileAttributes & FILE_ATTRIBUTE_ENCRYPTED) == FILE_ATTRIBUTE_ENCRYPTED )
    filebuff += "";
else
    filebuff +=("%*s", 30, FindFileData.cFileName); // not sure what this does!
