Hi,

Here is the code ,what i am using

HMODULE hmod;

HRSRC hr;

HGLOBAL gm;

char* lock;

hmod=LoadLibrary("testdll.dll");

hr=FindResource(hmod,MAKEINTRESOURCE(504),"GIF");

gm=LoadResource(hmod,hr);

lock=(char *)LockResource(gm);

if(hr == NULL)

MessageBox("This is not working");

else

MessageBox("This is working");

Here ,in this testdll.dll, we have stored Gif file as a resource and 504 is the resource identifier number. The resource type is "GIF".

But its not working. plz suggest me the solution

I can not remember exact code, but the fuction call
hr=FindResource(hmod,MAKEINTRESOURCE(504),"GIF");
is not correct.

you can try enumurating resource to find its resource ID.

Try using InitCommonControls or InitCommonControlsEx in the beginning of your program.

INITCOMMONCONTROLSEX InitCtrls;<br />
InitCtrls.dwSize = sizeof(INITCOMMONCONTROLSEX);<br />
InitCtrls.dwICC = ICC_BAR_CLASSES;	<br />
InitCommonControlsEx(&InitCtrls);//also check the returnvalue of this API

If it still does not work, you should try to add it through code:

hStatus = CreateWindowEx(0, STATUSCLASSNAME, NULL,<br />
        WS_CHILD | WS_VISIBLE | SBARS_SIZEGRIP, 0, 0, 0, 0,<br />
        hwnd, (HMENU)IDC_MAIN_STATUS, GetModuleHandle(NULL), NULL);<br />
int statwidths[] = {100, -1};<br />
SendMessage(hStatus, SB_SETPARTS, sizeof(statwidths)/sizeof(int), (LPARAM)statwidths);<br />
SendMessage(hStatus, SB_SETTEXT, 0, (LPARAM)"Some text");

kind regards,

Ward

Subclassed MFC CHeaderCtrl does only receive WM_NOTIFY in Debug

Hi,

(1) I have a CRszListCtrl : public CListCtrl

(2) which has a CustHeaderCtrl m_hdrCustom, where CustHeaderCtrl : public CHeaderCtrl

(3) CRszListCtrl has init() called from CDialog::OnInitDialog.

(4) This init() calls void CustHeaderCtrl::init(CListCtrl * const pList) with Argument this (i.e. self) to init its m_hdrCustom

(5) The code is

void CustHeaderCtrl::init(CListCtrl * const pList)<br />
{<br />
    m_pParentList = pList;<br />
    CHeaderCtrl * pHeader = m_pParentList->GetHeaderCtrl();<br />
    ASSERT( SubclassWindow(pHeader->GetSafeHwnd()) );<br />
}<br />

(6) To catch clicks on the header items I made handlers for WM_NOTIFY messages resent to the header by it's parent list which where routed via WM_NOTIFY_REFLECT macro or alternatively via OnChildNotify.

:(Both work fine but only in debug code!
Who can give a solution? Thank you!

regards Werner

Check what you have put in ASSERT macros, do not forget these are not compiled in Release mode.

MFC functions fail when called from exported function in DLL

I have made a regular dll in MFC. Here I have invoked an exported function in which I call a dialog using DoModal method. Now I added a static control on that dialog. Now, whenever I call that exported function in dll using an exe application i'm able to view that dialog, but the problem i'm facing is that i'm not able to get nor set data to the various controls(like static or edit) used in dialog. Like the MFC functions GetDlgItem, SetDlgItemText, SetWindowText, etc doesn't work.

Here is the piece of code

__declspec(dllexport) MyFun()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
CMyDialog dlg;
dlg.DoModal();
}

//Constructor for CMyDialog
CDlgTest::CDlgTest(CWnd* pParent /*=NULL*/)
: CDialog(CDlgTest::IDD, pParent)
{

this->SetDlgItemText(IDC_STATIC, "Mayank"); //Not working
}

You can't use SetDlgItemText in the constructor because the window (IDC_STATIC) has not yet been created.

You need to override the OnInitDialog (WM_INITDIALOG) and put your SetDlgItemText in that function, after the call to CDialog::OnInitDialog();

Hope that helps.

Is there some way how to reuse explorer's list control used for browsing the disk/local computer ?
I'd like to have this control integrated in my application with all default features (view modes like thumbnails/icons/...., default shell context menu, etc.

Thank you.

I think the WebBrowser should do it too. Insert the WebBrowser control in the project, and there you go. Then you must start with a real local address like "c:\\" etc. to start it with.

this is this.

Yes but after changing the folder original view mode is restored.
But thank you for help anyway, now I found IShellView for
direct usage of shell folder view, I'll examine it.

You don't need a file handle. use the document class's Serialize method instead
the CArchive parameter points to the file being opened (File -> Open) or saved (File -> Save)

void CTestAppDoc::Serialize(CArchive& ar)
{
	if (ar.IsStoring())
	{
		// code that writes to file
	}
	else
	{
		// code that reads from file
	}
}

look up Serialize[^] and CArchive[^] in MSDN for further details

I have an OCX Control, created with Visual C++ 6.0

I created another new OCX control, modifying the first one with very little changes. I renamed and registered the new one but it replaced the old one.

My problem is that I want both. Renaming the OCX and registering did not help me. How do i do this? Any help is greatly appreciated.

I am sorry if this is a wrong place to have posted this question.

It's not enough to rename it, you have to change it's CLSID too. Use uuidgen.exe tool to generate a new one and then register it again.
