Hi all,

They told me there's a function similar to
GetPathName()
_____________________
CFileDialog fd;
fd.GetPathName();
---------------------

which return the directory instead of the
full path.

Does anybody know which one is it ?

Thanx in advance,
Deamo16.

GetFolderPath()?

They hide that information in the documentation[^]

There is no need to start another thread when you already have one on this subject.

If they didn't HIDE it , it would be so much easier to find!

WTF | :WTF:

Yeah, I still can't believe how many people that develop production software can't even use API documentation. Can you imagine how bad the resulting products must be? Scary eh? Smile | :)

Hello,

Purpose: Search through a single column in a single worksheet to find duplicate cell items.

Description: I can use 'Find' without any problems for the inital search however when I try to use it again I get an COleException with either no error description or 'type mismatch' if I pass in an 'After' cell address. When I use the 'FindNext' method I get the error "FindNext method of Range class failed". I need help!

I'm using Office 2003, VC++ 2003, Automation import via VS.

CODE for 'FindNext':

FindNext( CString afterAddress, CRange *pFoundRange )
{
bool result = false;

CWorksheets excelWorksheets( m_CurrentWorkbook.get_Worksheets() );
CWorksheet Worksheet( excelWorksheets.get_Item( COleVariant( (short)m_CurrentWorksheetIndex ) ) );

Worksheet.Activate();

CRange excelRange( Worksheet.get_UsedRange() );

VARIANT afterCellAddress;

VariantInit( &afterCellAddress );

afterCellAddress.vt = VT_BSTR;
afterCellAddress.bstrVal = afterAddress.AllocSysString();

excelRange.Activate();

pFoundRange->AttachDispatch ( excelRange.FindNext( afterCellAddress ) );//'FindNext method of Range class failed' here

VariantClear( &afterCellAddress );

result = true;

return result;

}

CODE for 'Find' being used twice:

Find( CString dataToFind, CRange *pFoundRange, CString AfterAddress ){

CWorksheets excelWorksheets( m_CurrentWorkbook.get_Worksheets() );
CWorksheet Worksheet( excelWorksheets.get_Item( COleVariant( ( short )m_CurrentWorksheetIndex ) ) );

Worksheet.Activate();
CRange excelRange( Worksheet.get_UsedRange() );

VARIANT valueToFind;
VARIANT afterCellAddress;

VariantInit( &afterCellAddress );
VariantInit( &valueToFind );

afterCellAddress.vt = VT_BSTR;
valueToFind.vt = VT_BSTR;

afterCellAddress.bstrVal = AfterAddress.AllocSysString();
valueToFind.bstrVal = dataToFind.AllocSysString();

LPDISPATCH foundRange = NULL;

TRY{
if( AfterAddress.GetLength() > 0 ){
foundRange = excelRange.Find( valueToFind ,
afterCellAddress,
xlValues,
xlWhole,
vOptional,
xlNext,
vTrue,
vOptional,
vOptional );
}
else {
foundRange = excelRange.Find( valueToFind ,
vOptional,
xlValues,
xlWhole,
vOptional,
xlNext,
vTrue,
vOptional,
vOptional );
}

if( foundRange != NULL ){
pFoundRange->AttachDispatch ( foundRange );
}

VariantClear( &afterCellAddress );
VariantClear( &valueToFind );

result = true;
}
CATCH( CException, E ){
result = false;

}END_CATCH
}

Facing the same problem,
any help ??

Hi,
I'm using msvc6 and this code compiles:
class SomeClass
{
public:
class NestedClass
{
};

SomeClass (const NestedClass & n);
};

while this one doesn't:
class SomeClass
{
public:
class NestedClass
{
};

SomeClass (const SomeClass::NestedClass & n);
};

it gets this two errors:
D:\projects\stuff\stuff.h(31) : error C2629: unexpected 'class SomeClass ('
D:\projects\stuff\stuff.h(31) : error C2238: unexpected token(s) preceding ';'

is it a compiler bug, or set by the standard?

thanks,
yaniv

Hi all,

I've got the path to a file returned by a CFileDialog.
(Let's call it "path")
Now i wanna open another file in the same directory.
I know the name of the file, of course.
I tried with:
file.open(path+"\..\newfile.txt",std::ios::in);
but it tells me "not enough memory" at runtime.

How can i do that ?

Thanx in advance,
Desmo16.

How about...

PathRemoveFileSpec(path);
_tcscat(path, _T("\\newfile.txt"));
file.open(path,std::ios::in);

Mark

The compiler tells me

PathRemoveFileSpec(path);
identifier not found even with a research independent from the object

is there anything i should include ?

Thanx in advance,
Desmo16.

#include <shlwapi.h>

Removes the file name and backslash from the end of a pathname string.

Mark

#include WHAT ?

Sorry damn little angle brackets in html D'Oh! | :doh:

#include <shlwapi.h>

In additional you can use of CFile instead file.open Smile | :)

What do you need?Can you be more specific

Does anyone have or know where i can find source code for a very simple program that just produces a preview from a webcam (no capturing required) using DirectShow and VS2005?

Or can any one explain how i would do it myself?

The AmCap sample app in the DirectShow SDK (now in the Platform SDK) is fairly simple.

Mark

But there is no documentation to explain what all the classes do. I'm new to C++ and DirectShow and so i need a dummys guide to webcam previewing.

The DirectShow SDK IS the documentation. It's well documented actually.

For a beginner it's not real easy. You need to know C/C++, Windows API, enough COM to at least
handle creation/releasing of objects, and DirectShow classes.

A simpler alternative is Video for Windows[^].

Hi

i have one issue regarding EventLogType of event viewer.

I have written code for reading all events from event viewer. for getting event log type name like application, system and security, I refer registry path (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog). Form this path, I come to know how many event log type are and using the keyname, I read the event logs information.

My problem is that One machine (windows 2000 server) the eventlog names are differ from registry with eventviewer.

Ex.

In registry Application

In EventViewer . Application Logs

So I could not get the log information from event log viewer

I am using OpenEventLog() API

Thanks
