Hi.
How can I Extract .EXE(or DLL) file's Icons & other Resources.in Runtime and without other applications

With the samples that come with VC6.0 there is a sample application called IconPro which shows how to extract icons from exe and dll files. To use this to get other resources requires searching for example RT_BITMAP (for bitmaps) instead of RT_ICON.
The main functions to extract the resources are
FindResource
LoadResource
LockResource
FreeResource
Hope this helps

Hi.
How can I Find System's Drives And Drives Type with Windows API(s)

Hi,
Use GetDriveType(). Don't know how to enumerate, though.

To find system's drives try GetLogicalDrives, it returns a bitmask with all the drives available.
Use GetDriveType or GetVolumeInformation for extended information about the selected drive
Hope it helps!

For Windows < NT5 (aka W2k) it was true. Not so anymore I'm afraid.
For >= W2k you'll have to iterate volumes by using FindFirstVolume/FindNextVolume.
If you however are only interested in the drive-letter assigned volumes, this solution works.

1. open dll proj with classWizardMFC(dll) - type MFCExtension DLL.
2. add to resources Dialog
3. add new class for this dialog
4. write function with DoModal for the dialog , so:
--------------------------------------------------
extern "C" __declspec(dllexport) long CallDlg()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
CDlg1 dlg;
dlg.DoModal();
return 0;
}
-------------------------------------------------
5. It is not works ! Why ??????
below is the errors that I gets:
--------------------Configuration: dll1 - Win32 Debug--------------------
Compiling...
dll1.cpp

mfcs42d.lib(dllmodul.obj) : error LNK2005: _DllMain@12 already defined in dll1.obj

remove the AFX_MANAGE_STATE(AfxGetStaticModuleState()); line, you don't need it in an extension dll. It's only needed in regular mfc dlls

hi
i have class derived from CHeaderCtrl with own virtual DrawItem but it is never called
it is another class member and is created by .Create() call
(no problem with WM_ handlers)
what can be wrong?
t!
|
|
|
|
|
Are you sure you're using HDF_OWNERDRAW flag in HDITEM passed to CHeaderCtrl::InsertItem?
Tomasz Sowinski -- http://www.shooltz.com

|
|
|
|
i afraid i'm using
HDITEM hdi;
hdi.mask = HDI_TEXT | HDI_WIDTH | HDI_FORMAT;
hdi.fmt = HDF_STRING | HDF_LEFT | HDF_OWNERDRAW;
t!
|
|
|
|
|
You've mentioned in the first post that there's 'no problem with WM_ handlers'.
Does this mean that parent window gets WM_DRAWITEM as expected and the only problem is with forwarding to virtual DrawItem method in header?
Tomasz Sowinski -- http://www.shooltz.com

|
|
|
|
parent has to deal something with?
i thought it goes to myhdrctrl::onpaint or onsize and similars
t!
|
|
|
|
|
parent has to deal something with?
Yes, but MFC does this for you automatically. Can you use Spy++ and check if parent gets WM_DRAWITEM?
Tomasz Sowinski -- http://www.shooltz.com
|
|
|
|
|
yes parent gets wm_drawitem with header ctrl id (fprocessed: false)
t!
|
|
|
|
|
|
sorry but _is_ virtual
afxcmn.h
class CHeaderCtrl : public CWnd
virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
t!
|
|
|
|
|

You're right, it is virtual. But it doesn't buy you anything. You still need ON_WM_DRAWITEM_REFLECT.

wm_drawintem_reflect? where to find it?
i tried wm_drawintem but is not called too
t!
|
|
|
|
|
No, there's no message named WM_DRAWITEM_REFLECT. You need a macro in the message map.
BEGIN_MESSAGE_MAP(CYourHeader, CHeaderCtrl)
ON_WM_DRAWITEM_REFLECT()
END_MESSAGE_MAP()
This will connect your DrawItem method into MFC message handling mechanism. Parent window will call CYourHeader::DrawItem when handling WM_DRAWITEM.

nothing
i tried
afx_msg void DrawItem ( LPDRAWITEMSTRUCT lpDrawItemStruct );
into hdr.h too - the same
when i look to examples i have (tree-list-ctrls on cp) there is my version only, i see nothing like this
t!
|
|
|
|
|
Another idea: put the breakpoint in CHeaderCtrl::OnChildNotify. Does the program stop there?
