I have question,
If I have a container and then I insert excel into my application, using insert object,when the excel is incrusted the buttons, save, open, print are unhabilitated, What is what I have to do to habilitate this buttons?

Does somebody work with Excel Automation? Mad | :mad:

Read MSDN to learn the differences between an ActiveX control, and an OLE Document.

Can anybody tell me a resource for adding a Splash screen to a DLL. Splasher and other classes require a CWinApp or CMainFrm object - my DLL does not have these.

Basically, I want to display an intro or splash screen to a library DLL when not properly registered. It would go away after a short period.

Thanks

One solution is to simply implement an MFC DLL. As for the splash screen, one solution is a dialog box.

Since you don't know how the caller is going call your DLL, this is a really bad idea. It's best to return an error code and then let the calling application notify the user.

I really need some help here folks.

Im using VC++.net (vc++ v7.x)

Im trying to create a simple wizard based program. However nowhere can i find a decent tutorial or guide to help me work it out.

lots of tutorials, sorry a few tutorials talk about property pages and property sheets. Others about Cdialog and classes. Also alot make you click on a menu toolbar to bring up the wizard. I dont want this, what i want is when you click the .exe a single dialog screen appears straight away and then you use the Next and Back buttons to navigate between the pages.

Can anyone give me some help please, either some advice or a best way to do it tip, or a link to a decent tutorial one that MSN search cant find as ive looked. Im not looking for anyone to do it for me, just a big kick in the right direction please.

One problem that i have also found is that a couple of articles say i need to change the base class from one thing to something else but i dont see how i can do this it just doesnt let me.

Any advice, please im pulling my hair out.

Kind regards
Dave Long

Use the CPropertySheet class. Follow the same steps you would follow to create a standard property sheet, but call SetWizardMode() before you call DoModal().

Use Shell_NotifyIcon().

Change your app's initial size/position in CFrameWnd::PreCreateWindow().

I need help with some file operations.

What I want to do is replace a file with a modified version of that file and have the original filename retained.

For example:
Original.txt --> Modified_Original.tmp --> Original.txt

I know the complete pathname of the Original. The Original.txt file property is Read-Only, and this is where I get a problem.

What I have done is:

remove(szOriginalFilename);
// Rename the temporary file (modified version) to the original
CFile::Rename(szTempFilename,szOriginalFilename);

This works ONLY when the Original is Write-able. How do I change a file's R-W properties from code??

Thanks
Johnny

Use the CFile::SetStatus() method, or use SetFileAttributes().

Thanks! I'll try them out.

Is there a way to change the fonts inside a listview control.

Thanks

See SetFont method of CWnd or WM_SETFONT msg.

d:\\Program Files\\Windows Media Player\\wmplayer.exe

d:\Program Files\Windows Media Player\wmplayer.exe
I:\Music\Symphony\RichardClayderman\Lieberstraum.mp3

I want use ShellExecute function to active a application (WindowMediaPlayer9 or WinAmp) and open a MP3 file also (play that MP3)
but I can not do that function always return ERROR_FILE_NOT_FOUND
When I type
"d:\Program Files\Windows Media Player\wmplayer.exe" "I:\Music\Symphony\RichardClayderman\Lieberstraum.mp3"
in RUN DialogBox (Start/Run)...>> it works OKAY
Can you show me a way to get right result?
thank

CHAR szCommandLine[300]=STR_NULL;

What is STR_NULL defined as?

strcpy(szCommandLine,"\"d:\\Program Files\\Windows Media Player\\wmplayer.exe\" \"");
...
strcat(szCommandLine,"\"");

Why are you escaping the double-quotes?

If((INT)ShellExecute(NULL, NULL, szCommandLine...

Unless you really want to use wmplayer.exe, you can simply set szCommandLine equal to I:\\Music\\Symphony\\RichardClayderman\\Lieberstraum.mp3 and let the shell's association determine what app to run.

wonderful!
WinAmp' s activated auto to play that MP3 file
thank you Rose | [Rose]

thank you

#define STR_NULL ""

Hi,

Is there a place that shows what is the meaning of m_reason member of CArchiveException.

I used a try/catch in my code and aperantly I got an exception with m_cause=7, what does it mean ?

The only thing I did was to serialize another member of my class...

Thanks,

Shay

CArchiveException::badSchema

First,

Thank you.

I still can't understand why. I did bump the Schema in 1 but I also have a switch statement that do the right serialize based on the schema....

Shay

What I have found is the easiest method of handling schema changes (since the MFC Schema stuff does nothing) is to write out a couple of extra bytes in each object. This will let you do your own object versioning and conditional serialization. Example:

void MyClass::Serialize(CArchive &archive)
{
WORD wMagicNum;
WORD wVersion;

CObject::Serialize(archive);

if (archive.IsStoring())
{
archive << (WORD)0x4C53; // LS
archive << (WORD)4; // version

archive << m_cServerConfigName << m_cLoginHTMLFileName << m_cDefaultIPAddress;
archive << (WORD)m_bUseSSL << (WORD)m_wNumWorkerThreads;
archive << (DWORD)m_iInputBufferSize << (DWORD)m_iOutputBufferSize;
archive << (DWORD)m_iSQLBufferSize << (DWORD)m_iMaxParameters;

archive << m_cCurrentApplicationSetFileName;

archive << (WORD)m_bUseMailSender << m_cMailProfile << m_cMailProfilePassword << (DWORD)m_iMailWorkerThreadCount;
archive << m_cSMTPHost << (DWORD)m_iSMTPAuthenticationMode << m_cSMTPUserName;
archive << m_cSMTPPassword << (DWORD)m_iSMTPPort << m_cSMTPBoundIP << (DWORD)m_iMailTransportToUse;

archive << (WORD)m_bOutputPerformanceHeader << (WORD)m_bCompactOutputBuffer;

}
else
{
archive >> (WORD&)wMagicNum;
if (wMagicNum != 0x4C53)
{
TRACE("Bad id number in front of a LightningServer item\n");
AfxThrowArchiveException(CArchiveException::generic);
}

archive >> (WORD&)wVersion;

archive >> m_cServerConfigName >> m_cLoginHTMLFileName >> m_cDefaultIPAddress;
archive >> (WORD&)m_bUseSSL >> (WORD&)m_wNumWorkerThreads;
archive >> (DWORD&)m_iInputBufferSize >> (DWORD&)m_iOutputBufferSize;
archive >> (DWORD&)m_iSQLBufferSize >> (DWORD&)m_iMaxParameters;

archive >> m_cCurrentApplicationSetFileName;

if (wVersion > 0)
{
archive >> (WORD&)m_bUseMailSender >> m_cMailProfile >> m_cMailProfilePassword >> (DWORD&)m_iMailWorkerThreadCount;
if (wVersion > 1)
{
archive >> m_cSMTPHost >> (DWORD&)m_iSMTPAuthenticationMode >> m_cSMTPUserName;
archive >> m_cSMTPPassword >> (DWORD&)m_iSMTPPort >> m_cSMTPBoundIP >> (DWORD&)m_iMailTransportToUse;
}

if (wVersion > 2)
archive >> (WORD&)m_bOutputPerformanceHeader;

if (wVersion > 3)
archive >> (WORD&)m_bCompactOutputBuffer;
}
}
}

I want to make a application that supports form creation(a form editor), like in MS Access or in VC++ Dialog Editor, like the VB form editor. i want to add controls dynamically to CFormView . and want to give the user the ability to move, resize or select the control in design mode. Please if any one can help me i would be very greatfull to him/her.

Hi,
I write into Excel over COM
My Problem is the interface IDispatch. I can't get acces to a SeriesCollection object with this interface.
I've tried to map anotherone but this doesn't works. The compiler says the code is ok but when executing i got an invalid pointer massage

Here are some parts of my code:

_ApplicationPtr pXL;
pXL.CreateInstance(L"Excel.Application.9");
.
.
.
pXL->Range["Messwerte!B5"]->Value2= 35.6;
pXL->Range["Messwerte!B6"]->Value2= 32.7;
pXL->Range["Messwerte!B7"]->Value2= 33.6;
pXL->Range["Messwerte!B8"]->Value2= 37.6;
pXL->Range["Messwerte!B9"]->Value2= 34.6;

pXL->Charts->Add();
pXL->ActiveChart->SetSourceData(pXL->Range["Messwerte!B5:Messwerte!B9"], _variant_t((long)xlColumns) );
pXL->ActiveChart->ChartType = xlLineMarkers;
pXL->ActiveChart->Location(xlLocationAsObject,"Messwerte");
pSheet->Shapes->Item( _variant_t((long)1) )->Top = 0;
pSheet->Shapes->Item( _variant_t((long)1) )->Left = 0;
pSheet->Shapes->Item( _variant_t((long)1) )->Width = 400;
pSheet->Shapes->Item( _variant_t((long)1) )->Height = 200;
// it works until here now i want change some attributes of the chart so i have to use an SeriesCollection Object

IID IID_ISERIESCOLLECTION = {0x00020813-0x0000-0x0000-0xC000
0x000000000046};
ISeriesCollection *pscMyCollection;
pXL->ActiveChart->SeriesCollection( _variant_t((long)1) )->QueryInterface(IID_ISERIESCOLLECTION, (void**)&pscMyCollection);

pscMyCollection-> //here i want to acces members, e.g. Item, Add.. but it doesn't work

Thanks for Help
