no problem, but for future reference, some people around here aren't quite so forgiving. It is after all a programming forum, and not math.

In any case, Good Luck with the C++!! Big Grin | :-D

With the risk of being shot by Microsoft or a Java Guru, how do you think that programming has evolved the last 2 years?
Is the majority of applications still written in C/C++ (or even Cobol) or is anyone switching to VB or C#?
And what about Java? Are stilly many programmers switching to Java or has the migration stopped since the burst of the .com bubble?
Does anybody of you know if there any inquiries or reports that can be found on sites?

Confused | :confused:

I want to write a small program that copies files to couple directory including Program Files. Is there a function that returns the Program Files location? If there are 2 hard drives and both of them have Program Files folder, which one is returned?

SHGetSpecialFolderPath.. with
nFolder as CSIDL_COMMON_PROGRAMS, -- look in MSDN.

I think there is only ever 1 real Program Files folder?

And another way is to get the environement variable named ProgramFiles by just using getenv("ProgramFiles").

But i guess the first method is better

From the registry. Here's a snippet

const char FilesSection[] = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion";
const char FilesItem[] = "ProgramFilesDir";
char FilesPath[MAX_PATH] = {0};
DWORD size = sizeof(FilesPath);

if(!REG_Get(HKEY_LOCAL_MACHINE, FilesSection, FilesItem, FilesPath, &size))
    return(FALSE);

    char Temp[MAX_PATH] = {0};
if(!ExpandEnvironmentStrings(FilesPath, Temp, sizeof(Temp)))
    return(FALSE);

Be warned though you cannot write anything in the Program Files directory if you are running XP, depending on the user profile.

Im writing an MDI app, and I dont want the application to create / show a blank document when the application starts. I know that ProcessShellCommand calls either OnFileNew or OpenDocumentFile (depending on wether a file was specified in the command line). What can I do?

In your app's InitInstance, you should see some code like this:

// Parse command line for standard shell commands, DDE, file open
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
 
// Dispatch commands specified on the command line
if (!ProcessShellCommand(cmdInfo))
    return FALSE;
</code>

Add this line to it:

// Parse command line for standard shell commands, DDE, file open
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
 
cmdInfo.m_nShellCommand = CCommandLineInfo::FileNothing;
 
// Dispatch commands specified on the command line
if (!ProcessShellCommand(cmdInfo))
    return FALSE;
</code>

By default, m_nShellCommand is set to FileNew, which creates a new document for you automatically when the app starts.

arg.. i tried to replace my bitmap resource for my toolbar and now i crash everytime i get to the last line in red below.. can someone tell me what might cause SetBitmap() to crash like it is now? Cry | :((

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
	if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
		return -1;

	// get handle on high color bitmap for toolbar
	HBITMAP hBmp = static_cast<HBITMAP>(LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDB_SCTOOLBAR),
		IMAGE_BITMAP, 0, 0, LR_SHARED | LR_LOADMAP3DCOLORS));

	// create the toolbar
	if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
	| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | BTNS_SHOWTEXT | CBRS_SIZE_DYNAMIC) ||

	}
	<code>m_wndToolBar.SetBitmap(hBmp);</code> // set the high color bitmap to the toolbar

the problem is specifically this line:

HBITMAP hBmp = static_cast(LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDB_SCTOOLBAR),
		IMAGE_BITMAP, 0, 0, LR_SHARED | LR_LOADMAP3DCOLORS));

this function is setting hBmp to NULL now.. i have tried exporting from photoshop in 256 color, 16 bit, and 24 bit.. all of them crash.. any suggestions? basically all it is is a high color bitmap for my toolbar..

thanks in advance..

still a newb.. cut me some slack :P

u can use a time span CTimeSpan to calculate the time, then Step the progress accordingly, after few test, ull have a good statistic in order to smooth the progress appearence

Accessing rendered SVG

David Chamberlain20-Sep-02 2:56

David Chamberlain

20-Sep-02 2:56

I've got a desktop application in development in VC++ 6 that processes data and creates an SVG file that can be seen in a local html file that was built to show the SVG file and some supporting info. No network connection needed, no server, just local desktop.

What I would like to be able to do is to use the Adobe SVG viewer as an ActiveX control to read the SVG file and do the rendering, but instead of displaying the SVG in the application, I need to be able to access the rendered bitmap and operate on the individual pixels. Even converting the SVG into a JPG would allow me to use the CxImage or FreeImage library to read the JPG file and have access to the individual pixels.

A search on Google provides many hits on converting SVG into JPG, but they're all Java, and that won't cut it. I need some C++ code.

Has anyone done something like this that would be able/willing to share some code to get me started, or point me in the right direction? I need to be able to load, create, and manipulate the SVG ActiveX control in a non-visible manner, and I need access to the rendered bitmap.

Thanks,
Dave

Property Sheet

20-Sep-02 2:21

I have started a MDI project with CFormView as the base class.

I have inserted a property sheet using the Menu item: Project¦Add to Project¦Components and Controls ->property sheet. But I cannot view the property pages nor the frame. I give access to CMyProjView class to have the property sheet embedded into the CFormView.

Any ideas how to activate this property sheet?

If you need the FormView only for containing the property page, you could also use this [^]

Kash22-Sep-02 8:24

This does what I need it to do, but the code seems awfully longwinded for what it does. i.e. only 2 property pages.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
