Re: how to save the value/string of CFlexgrid cells as a file onto hard disk? - C / C++ / MFC Discussion Boards

you need to scrollbar horz and vertz and also you need to
event WM_lbuttonmouse and mousemove and wheelmouse with events scroll
with these functions you can find your answer

and if you draw shapes in dialog I suggest use WM_PAINT

and maybe it is some helpful to you
http://www.codeproject.com/dialog/scrollablechilddialog.asp[^]

actually i am working on it now. am painting the shapes in wm_paint ,and i added the scroll bars
one thing is left: when the largest shape becomes bigger than the child dialog boundary, i am supposed to enlarge the child dialog with keeping the same size seen by the user (the view port) and without causing the onpaint to draw on the parent dialog.
thanks alot for your reply

how to save the value/string of CFlexgrid cells as a file onto hard disk?

Frown | :(

I guess you will have to write them yourself. There are no inbuilt methods for this purpose AFAIK.

use the CFile class? and then read the value/string of every cells?
Is there any simple method?:->

:shrugs: Can't say.

Well I can suggest you this... I don't know how feasible this is...

Serialize(or write) the object into a file and then when you need it read back the object from file.

The flexgrid has option to save files as CSV. I did it over a year ago, so don't remember the details, but i do remmeber saving files as CSV from Flexgrid. Check the method listings in the help.

Check the SaveGrid method for FlexGrid,here is a quick look:
SaveGrid Method

Saves grid contents and format to a file.

Syntax

[form!]VSFlexGrid.SaveGrid FileName As String, SaveWhat As SaveLoadSettings, [ FixedCells As Boolean ]

Remarks

This method saves a grid to a binary or to a text file. The grid may be retrieved later with the LoadGrid method. Grids saved to text files may also be read by other programs, such as Microsoft Excel or Microsoft Word.

The parameters for the SaveGrid method are described below:

FileName As String

The name of the file to create, including the path. If a file with the same name already exists, it is overwritten.

SaveWhat As SaveLoadSettings

This parameter specifies what should be saved. Valid options are:

Constant
Value
Description

flexFileAll
0
Save all data and formatting information.

flexFileData
1
Save only the data, ignoring formatting information.

flexFileFormat
2
Save only the global formatting, ignoring the data.

flexFileCommaText
3
Save data to a comma-delimited text file.

flexFileTabText
4
Save data to a tab-delimited text file.

flexFileCustomText
5
Save data to a text file using the delimiters specified by the ClipSeparators property.

flexFileExcel
6
Save all data and formatting information to an Excel97 file. This filter does not support frozen color rows or columns.

Options As Variant (optional)

When saving and loading text files, this parameter allows you to specify whether fixed cells are saved and restored. The default is False, which means fixed cells are not saved or restored.

When saving and loading Excel files, this parameter allows you to specify the name or index of the sheet to be loaded, or the name of the sheet to be saved. If omitted, the first sheet is loaded.

The options for saving fixed rows, columns, and translated combo values include:

Constant
Value
Description

flexXLSaveFixedCells
3
Saves fixed cells.

flexXLSaveFixedRows
2
Saves fixed rows.

flexXLSaveFixedCols
1
Saves fixed columns.

flexXLSaveRaw
4
Saves raw (untranslated) data.

For example, the options can be written as:

fg.SaveGrid "book1.xls", flexFileExcel

fg.SaveGrid "book1.xls", flexFileExcel, "sheetName"

fg.SaveGrid "book1.xls", flexFileExcel, flexXLSaveFixedCells

fg.SaveGrid "book1.xls", flexFileExcel, flexXLSaveFixedRows

fg.SaveGrid "book1.xls", flexFileExcel, flexXLSaveFixedCols

fg.SaveGrid "book1.xls", flexFileExcel, flexXLSaveRaw

fg.SaveGrid "book1.xls", flexFileExcel, _
flexXLSaveFixedCells Or flexXLSaveRaw

Notes

Hi,
I have an MDI MFC VS2005 app. I added a dialog bar in resource view and changed the basze class from CDialog to CDialogBar.

I use following code to create the dialogbar.

Now it is created fine and it aligns at bottom as intended, but all the buttons on the dialogbar are disabled!!!.

What's going on here?

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

EnableDocking(CBRS_ALIGN_ANY);
m_launchbar.Create( this, IDD_LAUNCHBAR, CBRS_BOTTOM , IDD_LAUNCHBAR );

}

In addition to the above problem the OnShowWindow is fired only when exiting the app and never when the app is started.

IMPLEMENT_DYNAMIC(CLaunchbar, CDialogBar)

CLaunchbar::CLaunchbar(CWnd* pParent /*=NULL*/)
: CDialogBar()
{

}

CLaunchbar::~CLaunchbar()
{
}

void CLaunchbar::DoDataExchange(CDataExchange* pDX)
{
CDialogBar::DoDataExchange(pDX);
DDX_Control(pDX, IDC_LBREXITAPP, m_lbrExitApp);
}

BEGIN_MESSAGE_MAP(CLaunchbar, CDialogBar)
ON_WM_SHOWWINDOW( )
ON_BN_CLICKED(IDC_LBREXITAPP, &CLaunchbar::OnBnClickedLbrexitapp)
END_MESSAGE_MAP()

// CLaunchbar message handlers
void CLaunchbar::OnShowWindow( BOOL bShow, UINT nStatus )
{

}
void CLaunchbar::OnBnClickedLbrexitapp()
{
// TODO: Add your control notification handler code here
}

Any help please?

Write event handlers for the buttons.

Nibu thomas

already have event handlers for on click as folows:

public:
afx_msg void OnBnClickedLbrexitapp();

void CLaunchbar::OnBnClickedLbrexitapp()
{
// TODO: Add your control notification handler code here
}

you created button and declare function for buttons but
buttons are disable,right?

You must provide a message handler in the MainFrame class not in the DialogBar class.

Thanx for your input. I changed it from dialog bar to CDialog anywyas. I have much more control and flexibility that way. It's easy to position teh window even with CDialog.

But thanx for your help. I appreciate it.

Why oh why!!!

Then what is the use of a Dialog bar!!! Sigh | :sigh:

You just have to provide a message handler for the button in the main frame class. That's all. Nothing more nothing less. Just like you would do for a toolbar button. Smile | :)

So I know you can do this with Windows... cuz I turn winamp all the way down and I can still hear other applications...

I want to be able to mute only my application... how can I do this?

Thanks!

You can't. Windows XP doesn't have per-application volume controls. Windows Vista will do, but not XP. Winamp does this by modifying the audio data it is sending to Windows.

Yes there is!! I installed K-Lite, and there is "MediaPlayer Classic" which came from K-Lite installation. To change the volume of MediaPlayer Classic does not affect WinXp overall volume. (Windows MediaPlayer and RealPlayer do.)

What Media Player Classic does is process the audio before it sends it to Windows to change its volume. Windows XP does not have individual volume controls per application - that is a new feature coming with Windows Vista.

store the user preferred volume (usually 0 [mute] - 10) and send/check this whenever you play sound. the exact code depends on what/how you are playing audio

I have run into a problem with registration keys ".Default\\.Default". WHat I am trying to do is read the "Apps\\Events\\.Default\\.Default" value. I am trying to identify System sound events that are attached to a .wav file for inclusion in a list box.

Do you need to read with RegEnumValue?

When I try:
RegOpenKeyEx(HKEY_CURRENT_USER,"AppEvents\\EventLabels", 0L,KEY_READ, &SoundsKey);
and use:
RegEnumKeyEx(SoundsKey,dwIndex,lpSubKey,&dwSubKeysz,
NULL, lpData, &dwDatasz, &ftLastWriteTime);
to return the next level in the chain, and use:
RegOpenKeyEx(HKEY_CURRENT_USER,
("AppEvents\\EventLabels\\"+lpData),
0L,KEY_READ, &SoundsKey);
(the strings concatenated in code)
I get an error code.

oldmirco,
you get this error "AppEvents\\EventLabels\\"+lpData
or you get runtime error
