Hi,
I had a similar problem using the common font dialog in VB. As far as I can
remember you have to specify a type of font to list using one of the flags
otherwise Windows doesn't know which fonts to enumerate.
CF_WYSIWYG, CF_PRINTERFONTS or CF_TTONLY

Hi.
I have a strange problem: I want to use ChooseFont API function to display
font selection dialog. I wrote a procedure, compiled, but when I start the
application and press choose font from the menu, I get the message: "There
are no fonts instaled. Open Fonts folder in Control Panel to install
fonts.". Of course, fonts are installed. I have Windows 2000 and DevCpp
4.9.5.0. Can anyone tell me what could cause this? Here is the code I wrote
to display font dialog:
case WM_COMMAND:
switch(LOWORD(wParam))
{
case ID_FORMAT_FONT:
{
CHOOSEFONT chFont;
chFont.lStructSize=sizeof(CHOOSEFONT);
chFont.hwndOwner=hwnd;
chFont.lpLogFont=&lFont;
chFont.iPointSize=1;
chFont.Flags=CF_INITTOLOGFONTSTRUCT|CF_EFFECTS;
chFont.rgbColors=RGB(0,0,0);
chFont.nFontType=REGULAR_FONTTYPE;
if(!ChooseFont(&chFont))
MessageBox(hwnd,"Error in font
dialog","Error",MB_OK|MB_ICONSTOP);
}
break;
}

Hi, I just had a look at msdn.microsoft.com and this is the example they provide: HWND hwnd; // owner window HDC hdc; // display device context of owner window CHOOSEFONT cf; // common dialog box structure static LOGFONT lf; // logical font structure static DWORD rgbCurrent; // current text color HFONT hfont, hfontPrev; DWORD rgbPrev; // Initialize CHOOSEFONT ZeroMemory(&cf, sizeof(cf)); cf.lStructSize = sizeof (cf); cf.hwndOwner = hwnd; cf.lpLogFont = &lf; cf.rgbColors = rgbCurrent; cf.Flags = CF_SCREENFONTS | CF_EFFECTS; if (ChooseFont(&cf)==TRUE) { hfont = CreateFontIndirect(cf.lpLogFont); hfontPrev = SelectObject(hdc, hfont); rgbCurrent= cf.rgbColors; rgbPrev = SetTextColor(hdc, rgbCurrent); . . . } The only differences I can see is that: 1. They specify CF_SCREENFONTS, but you said you tried that 2. They ZeroMemory the CHOOSEFONT struct before use. Common dialog examples can be found at: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI /WindowsUserInterface/UserInput/CommonDialogBoxLibrary/UsingCommonDialogBoxe s.asp <http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinU I/WindowsUserInterface/UserInput/CommonDialogBoxLibrary/UsingCommonDialogBox es.asp> Also the full set of flags can be found at: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui /windowsuserinterface/userinput/commondialogboxlibrary/commondialogboxrefere nce/commondialogboxstructures/choosefont.asp <http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winu i/windowsuserinterface/userinput/commondialogboxlibrary/commondialogboxrefer ence/commondialogboxstructures/choosefont.asp> _____________________________ Marc Heiligers -----Original Message----- From: Vlada Djurovic [mailto:dj...@im...] Sent: 02 October 2002 09:39 AM To: 'Marc Heiligers'; 'DevC++ help' Subject: RE: [Dev-C++] fonts Hi, Marc Thanks for your help, but it still doesn't work.

Hi, Marc
Thanks for your help, but it still doesn't work. I still get the same
message. Can it be that I need to include some header files? I included
windows.h and commdlg.h. Or maybe there is a problem with my Windows
200?

First, Your mail is messed with the text you're answering and your answer, and it's really hard to read it. You shall define a LOGFONT before the use of the definition of the CHOOSEFONT and initialize the lpLogFont field of CHOOSEFONT with it. And then you select this on a HFONT, with CreateFontIndirect(LPLOGFONT). Anyway, if it's there and I didn't see it, check the CHOOSEFONT specification at your Win32 API reference, perhaps there is some field you should initialize due to the use of some option and you're not initializing it. I did a simple experiment with it and I had the same error (win2k), till I realized that I hadn't initialize the Flags field of CHOOSEFONT, and then it disappeared. |
