Re: How can resolve Error is :: "The Parameter is incorrect."

You are probably using a CTime object to set the time, and according to MSDN, the earliest date for a CTime is 1/1/1970.

If you use a COleDateTime object instead, the dates can be from 1/1/100 to 12/31/9999.

Hope that helps.

I m try this

COleDateTime dtMin;
COleDateTime dtMax;

dtMin = COleDateTime(100, 1, 1, 0, 0, 0);
dtMax = COleDateTime(9999, 12, 31, 0, 0, 0);

CDateTimeCtrl m_date;
m_date.SetRange(&dtMin, &dtMax);

but after using this the problem remains same.

By making sure you are using the ES_READONLY style instead of the WS_DISABLED style.

Ctrl + C. Just need to Check the Read Only Checkbox. try creating a sample program where u have 2 edit boxes in the dialog box and make one as read only and the other one as normal editbox. select the text in the read only and press ctrl+c and paste it in the the other edit box. it should work.

I think you want to cutomize your controls like buttons,treectrls and... so you can derived your class for example you can derived your class of CButton.See Creating Custom Controls[^] for more info.

problem is the data after this '\0'EOS is not assigned to CString object.

Well of course, this character is the end of string character so CString will detect the end of the string because of this character.

One of the CString constructors takes a char * pointer and a character count. I'm not sure, but that one may allow embedded nul's in the string.

Well, use a CArray (or better) a std::vector instead of a CString object.

My project is SDI that first view is CFromView derive class.
Then I add second view with CScrollView derive class.
In this view I want to print out the data So I add this function

BOOL CReportView::OnPreparePrinting(CPrintInfo* pInfo)
{
	CPrintDialog *dlg = new CPrintDialog(FALSE, PD_PAGENUMS);
	pInfo->m_pPD = dlg;
	pInfo->SetMinPage(1);
	pInfo->SetMaxPage(1);

	
	return DoPreparePrinting(pInfo);

}

while I run this function I got exception error at

BOOL CDialog::Create(LPCTSTR lpszTemplateName, CWnd* pParentWnd)

in file "dlgcore.cpp"

BOOL CDialog::Create(LPCTSTR lpszTemplateName, CWnd* pParentWnd)
{
	ASSERT(IS_INTRESOURCE(lpszTemplateName) ||
		AfxIsValidString(lpszTemplateName));

	m_lpszTemplateName = lpszTemplateName;  // used for help
	if (IS_INTRESOURCE(m_lpszTemplateName) && m_nIDHelp == 0)
		m_nIDHelp = LOWORD((DWORD_PTR)m_lpszTemplateName);

#ifdef _DEBUG
	if (!_AfxCheckDialogTemplate(lpszTemplateName, FALSE))
	{
Error Here >>>> ASSERT(FALSE);          // invalid dialog template name
		PostNcDestroy();        // cleanup if Create fails too soon
		return FALSE;
	}
#endif //_DEBUG

	HINSTANCE hInst = AfxFindResourceHandle(lpszTemplateName, RT_DIALOG);
	HRSRC hResource = ::FindResource(hInst, lpszTemplateName, RT_DIALOG);
	HGLOBAL hTemplate = LoadResource(hInst, hResource);
	BOOL bResult = CreateIndirect(hTemplate, pParentWnd, hInst);
	FreeResource(hTemplate);

	return bResult;
}

Please help me to solve this problem

erasing an element from a static vector.

Hi
I have declared static vectors in a function that i call multiple times:

static map<HWND, myVector<CString>> myMap;

On some of the function calls i want to remove elements from a vector:

myMap[hWindow].erase(iterator)

where iterator pointers to the element in the array I want to remove.

when I call myMap[hWindow].size() after erasing this element the size is the same as before??

Is this a consequences of using static vectors. Or am I doing something wrong?????
More likely option 2 Laugh | :laugh:

but wanted to check with some one who knows more about this stuff.
Many thanks

I don't think so.

steph5 wrote:

I think so.

I tried this:

HWND hWindow = (HWND)1234;
static std::map <HWND, vector <CString>> myMap;
typedef pair <HWND, vector <CString>> myPair;
vector <CString> myVector;
myVector.push_back(_T("string 1"));
myVector.push_back(_T("string 2"));
myVector.push_back(_T("string 3"));
myMap.insert(myPair(hWindow, myVector));
vector <CString>::size_type sizeBefore = myMap[hWindow].size();
vector <CString>::iterator iterator;
iterator = myMap[hWindow].begin();
myMap[hWindow].erase(iterator);
vector <CString>::size_type sizeAfter = myMap[hWindow].size();

sizeBefore is 3, sizeAfter is 2.
