Hi;
I'm using Toolkit 12.0.1 and CXTPPropExchangeXMLNode to store/load settings into/from XML files.
When calling PX_String to store empty CString values (GetLength() returns 0) and afterwards calling PX_String to load the empty string from the XML file, I get a string with three newline ASCII code 10 characters in it!
Is this a BUG or do I miss something?

Hi Oleg;
Here is my code to store the settings into the XML file:
bool StoreEventConfigSettings(struct _EventConfigOptions& gSettings, DWORD& dwError) {
TCHAR pszPath[MAX_PATH];
if (SHGetFolderPath(0, CSIDL_COMMON_APPDATA, 0, SHGFP_TYPE_CURRENT, pszPath)==S_OK) {
_tcscat(pszPath, _T("\\XRangeEye EventConfig 1.5"));
CXTPPropExchangeXMLNode px(FALSE, 0, _T("EventConfigSettings"));
px.SetCompactMode(FALSE);
if (px.OnBeforeExchange()) {
VERIFY(PX_String(&px, _T("DBConnect"), gSettings.EventConfigGeneralOptions.strService));
CXTPPropExchangeSection pxSubNode1(px.GetSection(_T("Service")));
VERIFY(PX_String(&pxSubNode1, _T("User"), gSettings.EventConfigServiceOptions.strUser));
VERIFY(PX_Blob(&pxSubNode1, _T("Security"), gSettings.EventConfigServiceOptions.lpPassword, gSettings.EventConfigServiceOptions.dwLen));
VERIFY(PX_String(&pxSubNode1, _T("Domain"), gSettings.EventConfigServiceOptions.strDomain));
_tcscat(pszPath, _T("\\Options.xml"));
return (px.SaveToFile(pszPath)==S_OK)
}
}
return false;
} |
And here is the counterpart...
bool LoadEventConfigSettings(struct _EventConfigOptions& gSettings)
{
TCHAR pszPath[MAX_PATH];
if (SHGetFolderPath(0, CSIDL_COMMON_APPDATA, 0, SHGFP_TYPE_CURRENT, pszPath)==S_OK)
{
_tcscat(pszPath, _T("\\XRangeEye EventConfig 1.5\\Options.xml"));
CXTPPropExchangeXMLNode px(TRUE, 0, _T("EventConfigSettings"));
if (px.LoadFromFile(pszPath))
{
VERIFY(PX_String(&px, _T("DBConnect"), gSettings.EventConfigGeneralOptions.strService));
CXTPPropExchangeSection pxSubNode1(px.GetSection(_T("Service")));
VERIFY(PX_String(&pxSubNode1, _T("User"), gSettings.EventConfigServiceOptions.strUser));
if (gSettings.EventConfigServiceOptions.lpPassword!=0) {
free(gSettings.EventConfigServiceOptions.lpPassword);
gSettings.EventConfigServiceOptions.lpPassword=0;
gSettings.EventConfigServiceOptions.dwLen=0;
}
VERIFY(PX_String(&pxSubNode1, _T("Domain"), gSettings.EventConfigServiceOptions.strDomain));
VERIFY(PX_Blob(&pxSubNode1, _T("Security"), gSettings.EventConfigServiceOptions.lpPassword, gSettings.EventConfigServiceOptions.dwLen));
return true;
}
}
XREventConfigOptions=XREventConfigDefaultOptions;
return false;
} |
In my case, most of the time the parameter "Domain" is an empty string. So storing the empty string and afterwards loading it results in a string with \n three times

Hi,
Please remove px.SetCompactMode(FALSE); line. or don't format XML:
px.SaveToFile(pszPath, FALSE);

Hi Oleg;
Shouldn't it also work with non compact mode and/or formatted XML?
Is this a bug of the MSXML implementation?
