In a WinCE MFC program, OnInitDialog(), I changed font of a Static text, but, it shows messy characters. same logic in my PC, I wrote a test MFC program. it works well.
Please help me to analyze the reason.
BOOL CTestDlg::OnInitDialog()
{
CDashApp *pApp ;
CDialog::OnInitDialog();
pApp = (CDashApp *) AfxGetApp();
ShowCursor( FALSE ) ;
InitConfigurationFile();
LoadDtcFile( pApp->g_PanelSettings.language );
if ( NULL != AddFontResource(TEXT("\\FlashDisk\\Startup\\FZYTK.TTF")) ) {
::SendMessage(HWND_BROADCAST,WM_FONTCHANGE,0,0);
}
DrawDash( BKG_DRAW ) ;
RefreshMainScreen( );
pApp->m_ActiveDlg = ACTIVE_DLG_TEST ;
LOGFONT lf;
CStatic *pEdit2 = new CStatic;
memset(&lf, 0, sizeof(LOGFONT));
lf.lfQuality = CLEARTYPE_QUALITY;
lf.lfWidth = 0;
WCHAR lffn[] = TEXT("FZYaoTi(OpenType)");
wcscpy(lf.lfFaceName,lffn);
lf.lfCharSet = GB2312_CHARSET;
if (m_Font1.m_hObject) {
m_Font1.DeleteObject();
}
m_Font1.CreateFontIndirect(&lf);
pEdit2 = (CStatic*)GetDlgItem( IDC_INFO_TOP);
GetDlgItem( IDC_INFO_TOP)->SetFont(&m_Font1,1);
pEdit2->SetWindowTextW(_T("??"));
return TRUE; }

Is the font installed on the target machine ?

... and MSDN says CreateFontIndirect would work for desktop apps only, so ...
~RaGE();

Thanks, CreateFontIndrect work for WinCE also.
Now it solved. seems when the IDE pop up a message window, ask me if I hope to change the character set, I clicked no.

Hi everyone,
here is an old and for me, still, an unanswered question:
How can I programmatically set width of an drop-down auto-complete list drawn implementing IAutoComplete2 interface, without re-sizing
of corresponding edit control, for example overriding edit controls WndProc? Is it possible at all on XP and up?
Thank You.

A dialog based program, I put a function to draw a string on the screen. the function is member function of TestDlg.h;
But if I put the function in TestDlg.cpp, the screen show some weird messy characters.
Then I put the same function in another cpp file, most of this file are global functions. JTest.cpp, with Jtest.h.
Weird thing is it works, screen can show correct characters.
Situation like:
TestDlg.cpp
IMPLEMENT_DYNAMIC (CTestDlg,CDialog)
...
void TestDlg::DrawInfoLabel(void)
{
CDC* pDC;
CRect rect(562,448,688,467);
CString lebelStr;
HDC hDC;
LOGFONT lf;
HFONT FontNew, FontOld;
pDC = GetDC();
hDC = pDC->GetSafeHdc();
memset(&lf, 0, sizeof(LOGFONT));
lf.lfHeight = -14 * GetDeviceCaps(hDC,LOGPIXELSY)/72;
lf.lfWeight = 0;
WCHAR lffn[] = TEXT("FZYaoTi(OpenType)");
wcscpy(lf.lfFaceName,lffn);
lf.lfCharSet = GB2312_CHARSET;
FontNew = CreateFontIndirect(&lf);
FontOld = (HFONT)SelectObject(hDC,FontNew);
pDC->SetTextColor(RGB(0xFF,0x00,0x00));
SetBkMode(hDC,TRANSPARENT);
DrawText(hDC,_T("??"),-1,rect,DT_CENTER|DT_VCENTER|DT_SINGLELINE);
SelectObject(hDC,FontOld);
DeleteObject(FontNew);
ReleaseDC(pDC);
}
In JTest.cpp
void TestDlg::DrawInfoLabel(void)
{
....
}
Every line is same, only difference is file name. I feel it is the following statement affect the screen output.
IMPLEMENT_DYNAMIC (CTestDlg,CDialog)
#include "resource.h"
#define APSTUDIO_READONLY_SYMBOLS
#include "afxres.h"
#include "newres.h"
#undef APSTUDIO_READONLY_SYMBOLS
#if !defined(AFX_RESOURCE_DLL) || defined(AFX_TARG_ENU)
#ifdef _WIN32
LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US
#endif //_WIN32
#ifdef APSTUDIO_INVOKED
1 TEXTINCLUDE
BEGIN
"resource.h\0"
END
2 TEXTINCLUDE
BEGIN
"#include ""afxres.h""\r\n"
"#include ""newres.h""\r\n"
"\0"
END
........
The above is .rc file.
Hope someone can explain that.
Thanks in advance

Hi,
This sounds like it might be related to code inline expansion. Where are you calling the function DrawInfoLabel()? Are you calling this from the WM_PAINT handler?
Best Wishes,

I call that function just in a general member function.
CTestDlg
{
public:
void refreshInfoLabel(void);
}
void CTestDlg::refreshInfoLabel(void)
{
DrawInfoLabel()
}

Hi,
It is generally not recommended to draw outside of the WM_PAINT/WM_ERASEBKGND handlers. When you draw outside of WM_PAINT you need to invalidate the window rectangle/region so that the subsystem knows to redraw it.
InvalidateRect function[^]
InvalidateRgn function[^]

I wonder if WM_PAINT message handler could display messages immediately.
or even I draw it in a member function, it would refresh in OnPaint() executed?

No. There is no guarantee that when your WM_PAINT message fires that the subsystem will redraw window contents unless the rectangle/region/window is marked invalid. This is an OS optimization to prevent excessive redrawing. (However with DWM enabled[^] the rules do change a bit)
Read all of this so that in the future you can help others: Painting and Drawing[^]

I am confused with SetFont() function.
I followed example code in MSDN, it works well in my laptop.
but, when I same code in my WinCE program, it dont work, font not change, show [] [] [] []
LOGFONT lf; CEdit *pEdit1;
lf.lfHeight = 12;
lf.lfWidth = 0;
memset(&lf, 0, sizeof(LOGFONT)); WCHAR lffn[] = TEXT("Simsun(OpenType)");
wcscpy(lf.lfFaceName,lffn);
lf.lfCharSet = GB2312_CHARSET;
if (m_font2.m_hObject) {
m_font2.DeleteObject();
}
m_font2.CreateFontIndirect(&lf);
pEdit1 = (CEdit *) GetDlgItem( IDC_EDIT1 );
pEdit1->SetFont(&m_font2);
SetDlgItemText(IDC_EDIT1, _T("公里") );
Appreciate any suggestions

Hi,
The code you pasted here appears to be bugged:
pEdit1 = (CEdit *) GetDlgItem( IDC_EDIT1 );
SetDlgItemText(IDC_INFO_PL, _T("公里") );

Changed. it is solved, but I don't know the reason. please refer to another question I posted.

Hi, in a dialog project member function, the results of retGetRect() confused me:
void CTestDlg::RefreshLabels(void)
{
CRect rect;
CEdit1 *pEdit1 = GetDlgItem(IDC_EDIT_TST1);
pEdit1->GetRect(&rect);
}
with breakpoint, I got
[tagRECT] = {top=350682312 bottom=15026448 left=15026448 right=784660}

Solved, it need to use GetClientRect(); then ClientToScreen()

Hi everybody!
I'm creating a program which use database.
My problem is: I use ExecuteSQl() to input data into my database but when i run it, I show an error "too few parameters. Expected 1".
CString path(_T("\',\'")), pathInt(_T("','"), rien(_T("NUL"));
reqPer = _T("insert into personne values (2014,\'") + nomPer + path + prenPer + path + datNaissPer + path + liNaisPer + path + domPer + _T("\',") + rien + _T(",\'") + numPiecPer + path + _T('M') + path + profPer + path + natPer + _T("\',") + rien + pathInt + rien + _T(")");
database.ExecuteSQL(reqPer);
|
|
|
|

You should check the final value of the reqPer string to see whether the SQL command is correctly formed. I would also strongly suggest you do not create SQL statements in the way you have done, as this leaves your code open to SQL injection, and the potential loss or corruption of your database. See the CRecordSet class[^] for the correct way to do it.

I saw it, but it's not very clear for me. Please, can you post a sample?!

Sorry, I don't have one. You need to either search for yourself, or spend time reading the documentation.

It will be correct, if i use this one?
sql.Format("INSERT INTO NomTable (Colone1,Colonn2, ....) VALUES(%d ,'%s','%s', ....)",m_Variable1,m_Variable2, ....);
db->ExecuteSQL(sql);

Please, I have order problem.
when I do this:
CRecordset recordset(&database);
CString temp, query;
query.Format(L"SELECT number FROM personne WHERE numPiece = '%s'", numPiecPer);
recordset.Open(CRecordset::snapshot, query, CRecordset::appendOnly);
while (!recordset.IsEOF())
{
recordset.GetFieldValue((short)0, temp);
messageBox(temp, 0, 0);
recordset.MoveNext();
}
It don't work.
