I have a CString object loaded with a string like "This is the first section$This is the second section$This is the end" so each section separated by '$'. I try to load the second section as csAnsprech = csComboBoxText.Mid( csComboBoxText.Find( '$') +1, csComboBoxText.ReverseFind( '$')); but this retrieves the second and third section, nut just the second one. What´s wrong here ?

int nPos = csComboBoxText.Find( '$') + 1;
csAnsprech = csComboBoxText.Mid( nPos , csComboBoxText.GetLength()- csComboBoxText.Find( '$',nPos ));

Hello RadioOpa,

try this:

<br />
int i =0;<br />
while(i < csComboBoxText.GetLength())<br />
{<br />
	if(csComboBoxText.GetAt(i) == '$') // if we found the first separator in the string<br />
	{<br />
	i++; // move one place to skip the separator<br />
	while(csComboBoxText.GetAt(i) != '$') // now copy all characters in your string, while not found the next separator<br />
	{<br />
		csAnsprech += csComboBoxText.GetAt(i);<br />
		i++; // move to the next character<br />
	}<br />
	}<br />
	i++;// move to the next character<br />
}<br />

i hope that helps you!
regards

P.S. that sample from nave ist very good, i want just to show you another way without Find-Functions to extract a part of string

Many thanks, both ways solving the problem are excellent.

I changed code as follows:

iFirstSection = csComboBoxText.Find( '$'); // Find first '$'
iSecondSection = csComboBoxText.Find( '$', iFirstSection +1); // Find second '$'

csFirma = csComboBoxText.Mid( 0, iFirstSection); // Get first string section
csFirma.TrimRight( ' ');
csOrt = csComboBoxText.Mid( iFirstSection +1, iSecondSection - iFirstSection); // Get second
csOrt.TrimRight( ' ');
csFirmaID = csComboBoxText.Mid( iSecondSection +1); // Get last section

The second param to Mid() is the # of characters, not the ending index. You can use AfxExtractSubString() to pick out the tokens.

hi
Thanks
Now i am facing another problem
char autocode[12];
stycpy(autocode,"1234");
CString csBuffer ="1234";
if(strcmp(autocode,(char*)(csBuffer.GetBuffer(csBuffer.GetLength()))))
{

csBuffer.ReleaseBuffer();
return TRUE;
}

Now , at csBuffer.ReleaseBuffer() ..it crashes ..
I dont understand why ...
I feel strcmp still holds the memory returned by csBuffer.GetBuffer right ?
can u help me solve it ?

Why don't you just do this?

char autocode[12];
strcpy(autocode,"1234");
CString csBuffer ="1234";

if(strcmp(autocode,(LPCTSTR)csBuffer)) return TRUE;

A CString is freed when it goes out of scope so you (normally) don't have to.

OT:
Why should it return TRUE for a difference between autocode and csBuffer?

You are going a long, long way just to compare strings. Note that you are not doing anything specific to CStrings, so it is a waste to use one. But since you have one, use its Compare(...) method:

CString csBuffer = _T( "1234" );
//
//
//
if( !csBuffer.Compare( _T( "1234" ) ) )
{
    // csBuffer == "1234"
}
else
{
    // csBuffer != "1234"
}

Peace!

as Cedric explained with a code sample, the CString class provides an operator = (const TCHAR*) which allows you to assign directly a CString with a char*...

char* codenew = "hello";
CString str = codenew;

What does __RPC_FAR do?

typedef /* [unique] */ IDispatch __RPC_FAR *LPDISPATCH;
What does this signify?

16 bit environments used to have near and far pointers, and __RPC_FAR used to indicate a far pointer. It is provided for compatibility reasons, it is defined as nothing.

1. place the following string somewhere in your "stdafx.h" file:

#include <afxpriv.h>
2. override DoModal() function in your dialog class:

int CSampleDialog::DoModal()
{
CDialogTemplate dlt;
int nResult;

// load dialog template
if (!dlt.Load(MAKEINTRESOURCE(CSampleDialog::IDD))) return -1;

// set your own font, for example "Arial", 10 pts.
dlt.SetFont("Arial", 10);

// get pointer to the modified dialog template
LPSTR pdata = (LPSTR)GlobalLock(dlt.m_hTemplate);

// let MFC know that you are using your own template
m_lpszTemplateName = NULL;
InitModalIndirect(pdata);

// display dialog box
nResult = CDialog::DoModal();

// unlock memory object
GlobalUnlock(dlt.m_hTemplate);

return nResult;
}

It may be reasonable to choose a font for your dialog box according to user-specified schemes (those in Control Panel / Display / Appearance). Unfortunately I was unable to find any simple ways to get font settings for the dialog boxes. A possible alternative is to use font settings for icon titles and some related controls (like tree and list controls), that can be retrieved by SystemParametersInfo() function. Here is a simple procedure that returns the face name and the size in points for this font:

void GetSystemIconFont(CString& strFontName,int& nPointSize)
{
LOGFONT lf;

// get LOGFONT structure for the icon font
SystemParametersInfo(SPI_GETICONTITLELOGFONT,sizeof(LOGFONT),&lf,0);

// getting number of pixels per logical inch
// along the display height
COLOR="#990000">
HDC hDC = ::GetDC(NULL);
int nLPixY = GetDeviceCaps(hDC, LOGPIXELSY);
::ReleaseDC(NULL,hDC);

// copy font parameters
nPointSize = -MulDiv(lf.lfHeight,72,nLPixY);
strFontName = lf.lfFaceName;
}

Thanks ashok..it works.

Should i have to overide the Create() function so that the font will change when dialog is created as Modless?

Yes..

Override create for modeles dialog.

Try that and revert me back whether it works fine or not.
