it is most likely you did not properly defined that.
here is the resource format for dialog boxes in fasm: Code: ; dialog label,title,x,y,cx,cy,style,exstyle,menu,fontname,fontsize dialog main_dialog,'window name',0,0,100,100,WS_CAPTION+WS_POPUP+WS_SYSMENU+DS_MODALFRAME,0,0,'terminal',8 ; dialogitem class,title,id,x,y,cx,cy,style,exstyle dialogitem 'static','some text',-1,10,10,90,90,WS_VISIBLE enddialog _________________ Asm For Wise Humans |

WS_CAPTION or WS_POPUP or WS_SYSMENU or DS_MODALFRAME it is all good.
But where DS_SETFONT? without this flag 0,0,'terminal',8 is ignored. |

DS_SETFONT, is used when you want to have a custom font made by you or any other personl and font data must be in resource section i.e. RT_FONT. not specifying DS_SETFONT means the application is going to use system fonts; where system font means any font is loaded by the OS or built-in or in font directory of the operating system; which in this case terminal is a system font. _________________ Asm For Wise Humans |

Ali.Z, if thou so sured that DS_SETFONT is for using only RT_FONT
before this Code: dialog main_dialog,'window name',0,0,100,100,WS_CAPTION+WS_POPUP+WS_SYSMENU+DS_MODALFRAME,0,0,'terminal',8 ; dialogitem class,title,id,x,y,cx,cy,style,exstyle dialogitem 'static','some text',-1,10,10,90,90,WS_VISIBLE enddialog Code: DS_SETFONT=0 or replace this Code: dialog main_dialog,'window name',0,0,100,100,WS_CAPTION+WS_POPUP+WS_SYSMENU+DS_MODALFRAME,0,0,'terminal',8 ; dialogitem class,title,id,x,y,cx,cy,style,exstyle dialogitem 'static','some text',-1,10,10,90,90,WS_VISIBLE enddialog with this Code: dialog main_dialog,'window name',0,0,100,100,WS_CAPTION+WS_POPUP+WS_SYSMENU+DS_MODALFRAME+0*0,0,0,'terminal',8 ; dialogitem class,title,id,x,y,cx,cy,style,exstyle dialogitem 'static','some text',-1,10,10,90,90,WS_VISIBLE enddialog Code: from adding +0*0 nothing changed (if nothing covered from pure newbie) Oh, how thou will be suprised. That is because of cheating: no matter willing programmer using DS_SETFONT or not, - it hardcoded in fasm macros. Thou could see that other assemblers & compilers have dialog resourse both without & with this flag. SO FOR CLEARNESS ALWAYS list DS_SETFONT in dialog resource flags. BE HONIEST WITH PEOPLE THAT THEY WOULD READ THOUR CODE. they shouldn`t make assumpions about this flag absense. |

I don't know if it is important, but the title says "at runtime" but the comments are discussing "at compile time".

revolution, in 1st post requester says that he have to change programmatically "at runtime", but he wants via resource "at compile time".

ressources are not necessary, you can also compose your windows by calling win32 functions related to window programming. |

During runtime you would use WM_SETFONT.
edit: WM_SETFONT for each control, not just the dialog. |

no DS_SETFONT needed only for initialization of dialog resource with current structure of items, without this flags members for font are excluded from structure - this behavior absent in standart fasm dialog init structure.

Well I'm creating my dialog using resources but I do prefer to change the font of the main dialog later programmatically during the runtime, let's just say I'm interested to know how also learn something new.

well here's the contents of .rc file:
Code: //Microsoft Developer Studio generated resource script. // #include "resource.h" #define APSTUDIO_READONLY_SYMBOLS ///////////////////////////////////////////////////////////////////////////// // // Generated from the TEXTINCLUDE 2 resource. // #include "afxres.h" ///////////////////////////////////////////////////////////////////////////// #undef APSTUDIO_READONLY_SYMBOLS ///////////////////////////////////////////////////////////////////////////// // English (U.S.) resources #if !defined(AFX_RESOURCE_DLL) || defined(AFX_TARG_ENU) #ifdef _WIN32 LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US #pragma code_page(1252) #endif //_WIN32 ///////////////////////////////////////////////////////////////////////////// // // Dialog // 150 RCDATA "devil.bmp" 151 RCDATA "bloody_font.bmp" 152 RCDATA "enochian_font.bmp" 160 RCDATA "devil.txt" 100 DIALOG DISCARDABLE 0, 0, 0, 0 STYLE DS_CENTER | WS_POPUP FONT 12, "Terminal" BEGIN END #endif // English (U.S.) resources ///////////////////////////////////////////////////////////////////////////// #ifndef APSTUDIO_INVOKED ///////////////////////////////////////////////////////////////////////////// // // Generated from the TEXTINCLUDE 3 resource. // ///////////////////////////////////////////////////////////////////////////// #endif // not APSTUDIO_INVOKED i've tried everything mentioned in this thread but still terminal font is ignored.... also WM_SETFONT for some reason is not working for me,so this brings us back to the zero ground,how can i change the font during the runtime using win32 api? |

Code:
invoke CreateFont,16,0,0,0,0,0,0,0,0,0,0,0,0,facename
mov ebx,eax
invoke GetDlgItem,[hwnddlg],control1_id
invoke SendMessage,eax,WM_SETFONT,ebx,TRUE
invoke GetDlgItem,[hwnddlg],control2_id
invoke SendMessage,eax,WM_SETFONT,ebx,TRUE
