You can use a modeless dialog. Use EnableWindow(FALSE) on your app's main window to prevent the
user from using the UI and create and show the modeless dialog. When your operation completes,
destroy the modeless dialog and call EnableWindow(TRUE) for the main window to re-enable it.

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.

They hide that information in the documentation[^]

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

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
}

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.

Mark Salsbery24-Oct-06 4:52

How about...

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

Mark

Desmo1624-Oct-06 5:07

24-Oct-06 5:07

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.
