You could try here Code Project[^]
Or use the CP site search and look for "XML Document Wrapper" for instance.

Hi Antony,
I have used that wrapper class you suggested already. It had a 'find' function in it, but it's pretty strangely coded that part.
When he finds it, he adds it to the root node. Not exactly what i wanted to do with it. It should return a CXMLNode* or NULL if not found.
|
|
|
|

It was quite a while ago that I looked at that class, I just remembered that there was a Find implementation.
If it generally finds a node then you ought to be able to change the function to return CXMLNode*.
CXMLNode* CXMLNode::Find(CXMLNode* rootNode, LPCTSTR nodeName, LPCTSTR nodeText, LPCTSTR attribName, LPCTSTR attribValue)
Where it adds the node to the root replace
CXMLNode *pNode = new CXMLNode(Nodes[i]);
rootNode->Nodes.Add(pNode);
with
return Nodes[i];
And right at the end of the function
Nodes[i]->Find(rootNode,nodeName,nodeText,attribName,attribValue);
}
return NULL;
}
For your purposes you will probably not need to pass rootNode to the function and therefore all refrences to it can be removed.

Yes. SelectNodes() and SelectSingleNode() returns nodes matching an XPath statement.

Hi.
Is it easy to integrate XPath functions into regular XML files?
selectNodes() is not a member function of IXMLDocument for example

I don't know what you mean. If you are using any parser that supports XPath queries ( MSXML does ) then it is integrated for you. You construct the XPath statement through whatever means is required to solve the current problem. You provide the statement as a text string to the parser engine (with MSXML it is the IXMLDOMDocument::SelectNodes() and SelectSingleNodes() methods) and it returns a node list of all nodes matching the XPath statement.
JensB wrote:

It is a member of IXMLDOMDocument. It inherits that method as well as selectSingleNode() from the IXMLDOMNode interface. That allows you to execute relative XPath statements.

Yes. This is verry handy and works great. I wasn't aware of the existence of 'XPath'.
Thanks alot for the excellent help.

Hello,
How does one do about rebuilding Classwizard's data/info?
I have just created some projects from scratch by adding the appropriate source files to them but, unfortunately, I seem to have lost all Classwizard data. Not that it matters the world, but ClassWizard is indeed handy.
Is there anything I can do to (re)solve this?
Thanks,
David

Delete the .CLW file from your project directory and then class wizard will rebuild the information the next time you run the class-wizard.

Hi there,
The problem is I didn't even have a .CLW file. I just added the source files I needed in to a blank static-lib project hoping that ClassWizard would then be available... but no chance! The menu item is even disabled.
What should I do now?
|
|
|
|
|
ClassWizard is a MFC facility. I'm not sure if class-wizard is supported in a static-lib, even if you set-up the lib to use MFC. I only have one static lib that uses MFC and I can't see any options to enable class-wizard for it.

Hi everybody,
I need to write a kind of scheduler program in MFC. As far as I know there is a SeTTimer
funtion but it only gives me periodic ON_TIMER message which is not a proper way to alert the program ,for example, at 03.agu.2004 16:30:00.
Please guide me.
Thanks,
Muharrem

here is you r solution buddy
,just check the current time every time the WM_TIMER message Generate.
like this way
CTime tm=CTime::GetCurentTime();

Don't you think It is not necessary to check every ,let say, one second if
time has alredy expired or not. I assume there should be some way shorter and smarter
to set a kind of timer for an absolute time. But I don't know how?
Any way thanks for your reply.

This sounds like a job for the ITaskScheduler interface. See also the ITask and ITaskTrigger interfaces.

 I am just starting with C++, and have a problem. I wrote a text game but the thing is some times I want the new question etc to start at the top of a clean black screen (that is erase all previous lines).
I could just put a pile of endl; but a couple of days ago somewhere on the site I saw a clrScrn; statment or something like that and remembered BASIC.
Could someone tell me the the #include and the correct way to use it.
Thanks in advance!

the DOS-command 'cls' clears the screen.
If you can execute this command...
Good luck.

Here is you solution
If you working in Text mode
see cls() function it is defined in <conio.h>
if you working in Graphis mode
see function cleardevice() ,it is defiend in graphics.h

>>erase all previous lines).
For dos baserd compiler... the function is: clrscr();
The header file for it is #include<conio.h>
conio=Console I/O
I hope that makes you happy.

im assuming you have Visual C++, unfortunatly VC++ doesnt come with the old functions like gotoxy() or clrscrn() that Dev-C++ offers
here is a ClearScreen() function i wrote along time ago (with SetXY() function)
void SetXY(int X, int Y){
COORD dwCoord;
dwCoord.X = X;
dwCoord.Y = Y;
SetConsoleCursorPosition(STDHANDLE,dwCoord);
}
void ClearScreen(){
COORD dwCoord;
DWORD nLength;
DWORD lpResult;
CONSOLE_SCREEN_BUFFER_INFO Info;
GetConsoleScreenBufferInfo(STDHANDLE, &Info);
dwCoord.X = 0;
dwCoord.Y = 0;
nLength = Info.dwSize.X * Info.dwSize.Y;
FillConsoleOutputCharacter(STDHANDLE, ' ', nLength, dwCoord, &lpResult);
SetXY(0,0);
}
ohh i almost forgot
#define STDHANDLE GetStdHandle(STD_OUTPUT_HANDLE)

I want to log data into MS-ACCESS from my application.
But if a machine does not have MS-ACCESS, will the application hang?
i also found that there is a microsoft access driver which is really needed instead of MS-ACESS.
Now in my application, i want to first search for the driver(instead of assuming that it is present) and then start logging. Can any1 please give me some knowledge in this matter?

A lot depends on the method you are using to communicate with Access?
With ADO, you should just need to redistribute MDAC.
This[^] article tells you the files need for redistributing a DAO app.

i seem to be having a problem using GetFileSize in MFC
when i get the file size of anything other than an .exe it returns 0
code sample
hFile = ::CreateFile( m_FileToSplit, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL );
if( hFile != INVALID_HANDLE_VALUE )
{
dwFileSize = ::GetFileSize( hFile, NULL );
//doesnt seem to work
//m_FileSize.Format( "File Size: %d KB", dwFileSize );
/**/
if( dwFileSize >= 0x100000 )
{
m_FileSize.Format( "%d%s", (dwFileSize/0x100000), " MB" );
}
else if( dwFileSize >= 0x40000000 )
{
m_FileSize.Format( "%d%s", (dwFileSize/0x40000000), " GB" );
}
else
{
m_FileSize.Format( "%d%s", (dwFileSize/0x100000), " KB" );
}
/**/
CloseHandle( hFile );
}
as you may have noticed my other problem
m_FileSize.Format( "File Size: %d KB", (dwFileSize /0x100000) );
doesnt work while
m_FileSize.Format( "%d%s", (dwFileSize/0x100000), " KB" );
does anyone know why?
extra prob: m_OutputDir.Format( "%s\\%s\\Output", FileDrive, FilePath );
puts double slashes in the edit box, when i do
m_OutputDir.Format( "%s\%s\Output", FileDrive, FilePath );
it only puts single slashes, and i get a warning that \% and \O are not valid escape sequences
