GUI app and winAPI calls

[aurel]

OK i will

so like this :

Declare customType Library

Function CreateWindowEx%& (ByVal dwExStyle~&, Byval lpClassName As _Offset, Byval lpWindowName As _Offset, Byval dwStyle~&, Byval x As Long, Byval y As Long, Byval nWidth As Long, Byval nHeight As Long, Byval hWndParent As Offset, Byval hMenu As _Offset, Byval hInstance As _Offset, Byval lpParam As _Offset)
End Declare

[aurel]

Just try to compile code and tell me why not exists even is customtype?

it compile ..but when i run it ..i get error ?

Code: (Select All)

It is very late here ..i will back to this tomorrow

That's ok. Direct all further requests for assistance to @vince and @mnrvovrfc

[vince]

oh my, what will we ever do without you, get over yourself

Hi Zak...did i say something wrong ..i don't get it  ?



I search trough all files you add to attachment and there is no anything about declaration

especially not about WNDCLASSEX ..also there is nothing  on Wiki site or in REFERENCE site too.

Maybe i should try with LoadLibrary and  load this dll.s if would work

[mnrvovrfc]

It's 3AM where I live and making this post. Maybe Balderdash isn't energetic, isn't used to being bugged by someone else.

I'm not used to being "referred" to. Love it when forum code messes up revealing my user number...

You have to be a bit patient now. What you're trying to do is difficult and the process might take a week or longer. We're only at this stubborn function with ten parameters or so, which has to create buttons and perhaps other controls not as obvious to someone else, besides what's obviously in the name of "CreateWindowEx".

<-- demonstrating their best talent now

@mnrvovrfc

What you're trying to do is difficult

In fact is not ...another thing is QB64 in general is not used very much for GUI winapi programming
and ther is included old WNDCLASSA structure
soe thinngs are screwed when i first time see this code , like LoadCursorW ..why not LoadCursorA
maybe is a way to use different headers much modern

[aurel]

another bad thing is that message loop is created with DO/LOOP
and in C/C++ most used way is with WHILE/WEND
and without strange message handlers like :

bRet = GetMesage

etc..etc...

[aurel]

I looked into mingW compiler include - winuser and there is structure declared:

typedef struct tagWNDCLASSEXA {
    UINT cbSize;
    UINT style;
    WNDPROC lpfnWndProc;
    int cbClsExtra;
    int cbWndExtra;
    HINSTANCE hInstance;
    HICON hIcon;
    HCURSOR hCursor;
    HBRUSH hbrBackground;
    LPCSTR lpszMenuName;
    LPCSTR lpszClassName;
    HICON hIconSm;
  } WNDCLASSEXA,*PWNDCLASSEXA,*NPWNDCLASSEXA,*LPWNDCLASSEXA;


which is what i expected ...so it is already there
then i need to look into QB64 source and check what is there declared and how ,
and i think that only old structure is used

which is this one :
typedef struct tagWNDCLASSA {
    UINT style;
    WNDPROC lpfnWndProc;
    int cbClsExtra;
    int cbWndExtra;
    HINSTANCE hInstance;
    HICON hIcon;
    HCURSOR hCursor;
    HBRUSH hbrBackground;
    LPCSTR lpszMenuName;
    LPCSTR lpszClassName;
  } WNDCLASSA,*PWNDCLASSA,*NPWNDCLASSA,*LPWNDCLASSA;
