Is it possible to change the background color of a menu from white to gray eg. RGB(222, 222, 222) without having an owner drawn menu?

I doubt it. You could try temporarilly changing the control panel colors, but this would effect all aplications and menus.

You can do that with SetMenuInfo() and set a new background brush - only works on 98+ and 2000+ however.

Thats quite strange that it wouldn't work with XP. I tried it anyways but even though the class members where showing up when I was filling in my MENUINFO struct the program failed to compile because MENUINFO was not recognized...Does this have anything to do with me running XP (I doubt it, I think...) and windows.h is included.

Regardless, what are some better alternatives to take care of XP Windows and below?

It does work with XP. I tried it on my XP machine and it works beautifully.
Are you declaring your CBrush object as a class member so it doesn't go out of scope?

/////////////////
From MSDN
/////////////////

The MENUINFO structure contains information about a menu.

typedef struct tagMENUINFO {
DWORD cbSize;
DWORD fMask;
DWORD dwStyle;
UINT cyMax;
HBRUSH hbrBack;
DWORD dwContextHelpID;
ULONG_PTR dwMenuData;
} MENUINFO, FAR *LPMENUINFO;
typedef MENUINFO CONST FAR *LPCMENUINFO;

Requirements
Windows NT/2000/XP: Included in Windows 2000 and later.
Windows 95/98/Me: Included in Windows 98 and later.
Header: Declared in Winuser.h; include Windows.h.

Actually when I declare a MENUINFO struct eg. MENUINFO mi and then proceed to iniatilize the members of MENUINFO they are coming up on the classwizard (or whatever it is called). When I try to compile it though it does not recognize MENUINFO or SetMenuItem. I have included Windows.h. Are there any other headers necessary for it to work? (I am using Visual C++ 6.0)

I am using VC++ 7.0 but that shouldn't matter here.

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
...

CMenu *pMainMenu=GetMenu();
if(pMainMenu == NULL)
return...

CBitmap bm1;
bm1.LoadBitmap(IDB_MENU); //I made a small gradient bitmap (IDB_MENU)
m_MenuBrush.CreatePatternBrush(&bm1); //m_MenuBrush is a CBrush

MENUINFO mi;
mi.cbSize = sizeof(MENUINFO);
mi.fMask = MIM_BACKGROUND;
mi.hbrBack =m_MenuBrush;

CMenu* pMenuSub0 = pMainMenu->GetSubMenu(0); //File
CMenu* pMenuSub1 = pMainMenu->GetSubMenu(1); //Edit
CMenu* pMenuSub2 = pMainMenu->GetSubMenu(2); //View
CMenu* pMenuSub3 = pMainMenu->GetSubMenu(3); //About

// TODO: Should do some error checks for NULL pointers...
pMenuSub0->SetMenuInfo(&mi);
pMenuSub1->SetMenuInfo(&mi);
pMenuSub2->SetMenuInfo(&mi);
pMenuSub3->SetMenuInfo(&mi);

SSL Client for desktop Windows

Netmeisters,

I need to write an SSL client in C++ for desktop Windows. I've read Rescorla's excellent SSL book and done a fair amount of SSL programming, using C and openSSL for Linux, eVC++ for the Pocket PC, and java. Although the Pocket PC project might seem similar, apparently WinCE provides quite different SSL facilities than desktop Windows. I haven't found any books on the subject (Rescorla explicitly avoids Windows) and I haven't found much on msdn.

So I'd really appreciate a pointer to some documentation that might help me get started. I'd like to know if desktop Windows provides facilities for SSL, and if so, how to use them. (If not, I'll just use openSSL.)

Thanks very much,

Matthew Fleming

Maybe this can be some starter for you:

This is an example of client-server connection, you can find all functions required for that and then search for appropriate documentation when needed.

Why this is different? (CString copying over pszTitle)...

Joan M19-Mar-03 7:47

I have an array of property pages and I change their caption/title dynamically...

This works in the commented way, but when I try to do it using the non commented way, it crashes... (I'd like to know why)...

PREMISSES:

THE CASE THAT WORKS:
I have an array of property pages.
I have an array of titles.
Those two are members of the property sheet class.
THE CASE THAT DON'T WORKS:
I have an array of property pages.
I have one CString var declared inside the cosntructor of the property sheet class that will be used to store all the titles in the property pages...

THE CODE

{
...

this->m_ArrPPDlgParametritzacions[iNumPPags].m_psp.dwFlags |= PSP_USETITLE;  <code>// NOTHING TO DO...</code>
this->m_ArrPPDlgParametritzacions[iNumPPags].m_psp.dwFlags &= ~PSP_HASHELP; <code>// NOTHING TO DO...</code>
					
//m_ArrTitolsPropertyPages[iNumPPags].Format("%s",((char *)pxmlNode->attributes->getNamedItem("EtiquetaDescriptiva")->Gettext()));  <code>// THIS ONE WORKS OK...</code>

csTitolPPag = ((char *)pxmlNode->attributes->getNamedItem("EtiquetaDescriptiva")->Gettext()); <code>// THIS ONE WILL FAIL...</code>

this->m_ArrPPDlgParametritzacions[iNumPPags].m_psp.pszTitle = csTitolPPag;//m_ArrTitolsPropertyPages[iNumPPags];  <code>// IF I USE THE COMMENTED CODE EVERYTHING IS ALLRIGHT, BUT IF I USE THE ONE THAT's NOT COMMENTED, THEN THE TITLES ARE STRANGE (SOMETHING LIKE THIS:"@#~|@#€|~€|~|"...)</code>
					
this->AddPage(&m_ArrPPDlgParametritzacions[iNumPPags]); <code>// NOTHING TO DO...</code>

iNumPPags++; <code>// NOTHING TO DO...</code>
}

Any idea?

It's not a vital thing, I can live having an array of CStrings using memory, but it would be better to be able to do it without the array...

thank you in advance...

Tim Smith19-Mar-03 8:02

I would imagine that csTitolPPag is just a local string variable. The problem you are having is that

this->m_ArrPPDlgParametritzacions[iNumPPags].m_psp.pszTitle

is nothing more than a pointer to a character string. So when csTitolPPag goes out of scope, the string is deleted and thus pszTitle now points to trash.

Tim Smith

I'm going to patent thought. I have yet to see any prior art.

You would have to find the length of the string you are copying, then allocate a character array on the heap with length + 1 size, do a memset to set this new memory to 0, do a memcpy from the CString's psz pointer to this new memory, then set the array psz to be the new pointer. That way the memory will always be there in the array psz. Just be sure to do a delete [] on this array psz when this array is no longer needed, or will get a memory leak. (The memset to 0 may not be needed, it may be done automatically when call new.)

Hi How to load a resource on his name (for example IDB_BITMAP1), but it is not known ID. And whether it is possible?

IDB_WHATEVER is a mnemonic for a numerical ID, not a name. The mnemonic is #define'ed in a header file named resource.h by default.
Maybe you have just forgotten to #include resource.h?

Do you mean load it as a string name? If you are asking that exclude the MAKEINTRESOURCE parameter, I don't really understand the question though...

Syncronizing thread destruction?

clintsinger19-Mar-03 7:10

Hi Everyone,

I have an application that has a thread within a thread. When I delete the parent it is suppose to delete the child thread within the destructor. Unforetunately I am running into problems where the memory has already been freed (at least that is what I think has happened) and trying to free the resources are used by the threads.

When I run the application through boundschecker I don't see this problem at all so I think it has to do with some race condition. Is there some documentation on how to properly and effectively control the destruction of threads?

Cheers,
Clint

Neville Franks19-Mar-03 8:51

What do you mean by "delete" the thread? The parent thread should ask the child thread to end, and then it should end. Using CEvent is a good way to do this.

I was using an user interface thread to do the trick. I changed over to a worker thread and now everything seems to be better. I think the problem had to do with the self deleting nature of user threads. Now I explicitly control who deletes and when.

Sincerly,
Clint

override OnCompareItem for the combo, then use the COMPAREITEMSTRUCTs that you will receive in that function to determine which two items are being compared. return -1,0,1 as appropriate.
