I've added a Html Browser control to a Dialog in MFC. Initially it is displayed with white background. I want ot change to some other color. How to do this?
|
|
|
|
|
Don't you need to do this via HTML ?
Watched code never compiles.
|
|
|
|
|
No. Through C++/MFC code.
|

maximilien is right; the window doesn't belong to you, you've given it to the web browser
you can either embed an html resource in your own exe/dll and Navigate2 to it using the res:// namespace (see http://msdn.microsoft.com/en-us/library/aa767740.aspx[^]) or you can dynamically build an HTMLDocument2 and use IPersistStream to get it into the web browser
I'd choose the res protocol - much simpler

well, if u insist on it, subclass your web browser control. I think the CExplorer class (generated from web browser activeX) would be derived from CWnd. Handle WM_PAINT or ON_WM_ERASEBKGND messages in it. do your background painting there.
hopefully this may work.
DECLARE_MESSAGE_MAP()
afx_msg BOOL OnEraseBkgnd(CDC* pDC);
BEGIN_MESSAGE_MAP(CExplorer, CWnd)
ON_WM_ERASEBKGND()
END_MESSAGE_MAP()
BOOL CExplorer1::OnEraseBkgnd(CDC* pDC)
{
CRect rc;
GetClientRect(&rc);
pDC->FillSolidRect(&rc, RGB(255, 0, 0));
return TRUE;
}
*But this lives only till you load your first web page in browser control.

Yes it has to work since CExplorer1 is also Derived From CWnd. and mark your comment as answer.My 5.

Using the following code to get the file type icon in the dll, such as .exe .cpp .c .h file icon
SHFILEINFO sInfo;
SHGetFileInfo(strTempTest,bIsDir ? FILE_ATTRIBUTE_DIRECTORY : FILE_ATTRIBUTE_NORMAL,&sInfo,sizeof(sInfo),
SHGFI_USEFILEATTRIBUTES | SHGFI_SMALLICON | SHGFI_SYSICONINDEX);
using following code to set the image list to ListCtrl
SHFILEINFO sfi;
HIMAGELIST imagelist;
imagelist=(HIMAGELIST)SHGetFileInfo(_T(""),
0,
&sfi,
sizeof(SHFILEINFO),
SHGFI_SYSICONINDEX | SHGFI_SMALLICON ) ;
if(imagelist!=NULL)
{
SetItemImage(CImageList::FromHandle(imagelist),0);
}
But only the folder icon can be display. the file icon cannot show.
But I find a strange thing that if adding the following code in the main application, the icon of the .cpp file in DLL can display.
CoInitialize(0);
CString strTempTest;
int nPos = strName.ReverseFind(_T('.'));
if(nPos != -1)
strTempTest = strName.Right(strName.GetLength() - nPos);
else
{
if(!bIsDir)
strTempTest = strName;
else
strTempTest = _T("C:\\Windows");
}
SHFILEINFO sInfo;
SHGetFileInfo(_T(".cpp"), (bIsDir ? FILE_ATTRIBUTE_DIRECTORY : 0), &sInfo, sizeof(sInfo),
SHGFI_USEFILEATTRIBUTES | SHGFI_SMALLICON | SHGFI_ICON);
if (sInfo.hIcon)
DestroyIcon(sInfo.hIcon);
I donot know why. I google serveral times, but cannot get reason.

Are you making a copy of the image list and using that copy as the list view's imagelist? If so, that's the problem.
Each process gets its own copy of the system imagelist. That copy only contains a handful of icons at first. When you query for a file type's icon the first time, the icon is added to your process's copy of the imagelist.
If you use the HIMAGELIST returned by SHGetFileInfo as the list view's image list, and be sure that the list control has LVS_SHAREIMAGELISTS so it doesn't destroy the imagelist unexpectedly, you should be able to use new icons right away as they are added.

Michael's given you a good answer. I had exactly the same problem a while ago with drive icons.
Have a look at my article (and especially the comments) for some solutions:

Oh yeah, I resolved this problem. After move the set imageList code from the my ListCtrl controls.
But I donot know why it is.

Hi all .
Please tell me if I can integrate more object data types into a single MFC data structures ( Array , List or Map ).
If I have an CStringArray object , let's say m_saType , ( CStringArray type ) , and m_saItem ( CStringArray type too ) , and m_saPerson ( CStringArray type too ) ... how can I integrate all togheter into CObList MFC object , because I want to serialize all m_saType, m_saItem, m_saPerson into a single file on disk.
Thank you . I accept any ideea .
|
|
|
|
|
m_saType.Serialize(ar);
m_saItem.Serialize(ar);
m_saPerson.Serialize(ar);
Of course a better way is to declare a CObject derived class CPerson with CString members m_sType, m_sItem, m_sPerson
Implementing Serialize in this class the using a CObList and calling its Serialize...
|
|
|
|
|
#include <afxtempl.h>
class CDataPack : public CObject
{
public:
CStringArray m_saType;
CStringArray m_saItem;
CStringArray m_saPerson;
const CDataPack& operator=(const CDataPack& rdp)
{
m_saType.Copy(rdp.m_saType);
m_saItem.Copy(rdp.m_saItem);
m_saPerson.Copy(rdp.m_saPerson);
return *this;
}
BOOL IsSerializable() const { return TRUE; }
virtual void Serialize(CArchive& ar)
{
m_saType.Serialize(ar);
m_saItem.Serialize(ar);
m_saPerson.Serialize(ar);
}
};
typedef CArray<CDataPack, CDataPack&> CDataPackType;
void AnyFunc()
{
CString strElement(_T("An Element"));
CDataPack pkt;
pkt.m_saType.Add(strElement);
pkt.m_saItem.Add(strElement);
pkt.m_saPerson.Add(strElement);
CDataPackType arrData;
arrData.Add(pkt);
CFile file;
CArchive ar(&file, CArchive::store);
arrData.Serialize(ar);
}
If you don't want to use template counterpart, you can also use CObArray or even CPtrArray (or List ones such as CObList, CPtrList, see afxcoll.h). Just beware cleanup of objects.

Thank you very much ! You are very kind !
And if gave me good ideas , I push my luck and ask more : which structure of collection data you choose if you want to clone 3 SQL tables , every one with one unique key integer type and other fiels is strings , but keep link between tables through those unique key integer ?
|
|

I think, you mean which collection class? If so, Array is more efficient on random access.
I also think, you need to access the elements with Primary Keys/Forein Keys in master-detail relationships.
If you need rows in sorted order, you can fill this array sorted. You can take advantage of SQL's SELECT with ORDER BY clause while filling. If the array is sorted, you can access its items by using binary search to speed up searches.
If you just need to access items by the key, you can simply employ CMap to access its elements with key-value pair.
typedef CMap<int, int, CDataPack, CDataPack&> CDataPackMap;
You need to keep relationships yourself, or maybe, you may create more sophisticated structures.
[edit]BTW, Not at all. [/edit]

I think that CMap is most good ideea . Thanks again . Best wishes !

Hi
I have a MFC C++ project that calls a C# COM dll, which is registered on my development machine. However, when I step through the code, and it reaches the CreateDespatch passing in the GUID as the parameter, it throws an error "Invalid class string".
Trying to resolve this issue, I feel that I have reached a dead end, and in need of help. Typically this is caused by the dll not being registered, but it is and I can see in regedit! So, what is causing this problem? Can anyone please help me?
Thanks
|

|

Do you need to pass the string as wide characters (Unicode)?
|
|
|
|
|
CreateDispatch takes a CLSID GUID or a progid String
so - you do have the following entry?
HKCR\CLSID\{GUID}\InprocServer32
as an aside, it's (IMO) significantly easier to use ATL smart pointers than all the hoop-jumping IDispatch imposes ...
|
|
|
|
|
Which of these formats[^] are you using, and what is the exact content of your parameter?
The best things in life are not things.
