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().

Changing file properties

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().

Can you show me a way to get right result?

CHAR szCommandLine[300]=STR_NULL;
CHAR szFileName[255]=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.

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

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....

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;
}
}

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

Creating multiple buttons with one resource

jimNLX7-May-03 7:45

7-May-03 7:45

I'm trying to create multiple buttons on a dialog page dynamically and have been able to get the buttons to appear, but i can't get the tools tips to work. Before I did this I was using static buttons and they worked fine. Now everything works except the tool tip. Could this be because I'm just using one resource button on that dialog page?

m_Icon[ndx].Create(_T(""), WS_CHILD | WS_VISIBLE | WS_TABSTOP , CRect(0, 0, 0, 0), this,IDC_BTN );//IDC_BTN is the only resource on dialog created in the dialog editor

Any idea to the limit of the number of objects that can be put on a page? Looks like I may have a max of 600 plus all the stuff to make the page into a x/y graph.

Thanks for any help

dll memory and shared segment question

keyser_soze7-May-03 7:41

keyser_soze

7-May-03 7:41

As I understand it, applications which share a dll will share the code segment of the dll. Each application will get a new data segment for the data in the dll.

This can be overridden with the #pragmas such that a shared data segment can be used.

And I understand that variables must be initilized in order to be in that data segment.

Now when I create a class, can I specify what data segment it's data members will be in?

related question:

Let's say I have an array[] of some type that is supposed to be member data of a class. Should I create it as global (to the shared memory segment) and then only have a pointer to it in the class? If so, will all instantiations of the dll class point to the same data?

Thanks,

Is it possible to have one button do the function of two buttons in MFC.

Is it possible to have one button do the function of two buttons in MFC.
For example: I have two buttons Beginner Mode, Advanced Mode. The beginner mode puts the user in different settings than the advanced mode. I want them to both be in one button., so when the user clicks on beginner mode, the beginner settings show and the button text changes to advanced mode.

well, you can internally keep track of the mode via a variable, lets say bool bAdvancedMode = false. Depending on the value you can handle it like that:

voice OnButtonClick()
{
    if(bAdvancedMode)
       ShowAdvancedProperties();
    else
       ShowBeginnerProperties();
}

you can,

you need to keep a variable somewhere to keep the "mode" you're in.

you can also use a checkbox, to toggle on/off the advanced/beginner mode.

in the case of the checkbox, the button itself becomes the variable (unless it's private, or you need the variable to be a global state)

Max.
