Remove the WS_SYSMENU style from your window. Keep in mind that this will also disable Alt-Space as well.

I have a static library I have compiled with VS.Net -- the library compiles correctly. However, when I try to link against it I get link errors for multiply-defined symbols such as:
CWPDataManager error LNK2005: "public: class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> > & __thiscall std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >::operator+=(char)" (??Y?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAEAAV01@D@Z) already defined in MyDateD.lib(MyDate.obj)
My library makes use of std::string (as you can see above) and I've put the approriate #ifndef include guards in the library .h file. So, why do I get these link errors when I build my app and link against my libray? Anyone know where my problem is?
Thanks,

Are there functions in the DLL that returns a pointer or reference to a string object? If so, one solution is to do return by value.

Well, it's not a DLL - it's a static library. I have one function that takes a string by reference (consequently this is where the link errors arise from -- it's the only function that uses string). The function return is void and the string that is passed by reference is modified within the function.
The function (inside the library) looks like this:
void CMyClass::format(const char* fmt, string& dest)
{
...
(modify dest)
...
}

Okay.
See if you can pass in a const string and return the modified string instead of void.

That's usually caused by the build settings for the LIB using one form of CRT linking (static or DLL) and the executable using the other.

in my OnPaint, i am drawing to a memory DC, then blitting to the screen. if i do memDC.DrawFocusRect(...), then Blt, the rectangle turns out light blue (ie. wrong). but if i Blt then draw the focus rect onto the screen DC, it comes out black-and-white dashed (as it should).
memDC.DrawFocusRect(CRect(10,10,100,100));
dc.BitBlt(frameRect.left, frameRect.top, frameRect.Width(), frameRect.Height(), &memDC, 0,0, SRCCOPY);
memDC.SelectObject(ob);
dc.DrawFocusRect(CRect(10,10,100,100));

play around with SetTextColor and SetBkColor for that device, i'm not exactly sure which parameters you'll need but changing those affects the focus rect

Is the mem DC's setup exactly the same as the screen DC?
|
|
|
|

i think it is...
CPaintDC dc(this);
CDialog::OnPaint();
CDC memDC;
if (memDC.CreateCompatibleDC(&dc))
{
CBitmap bmp;
if (bmp.CreateCompatibleBitmap(&dc, frameRect.Width(), frameRect.Height()))
{
CBitmap *ob = memDC.SelectObject(&bmp);
if (ob)
{
... draw the stuff in here
-c

This suggestion may be silly, but worth the try: initialize the memDC before calling CDialog::OnPaint(). Something like:
CPaintDC dc(this);
CDC memDC;
BOOL bCreated = memDC.CreateCompatibleDC(&dc);
CDialog::OnPaint();
if(bCreated)
{
...
}
Good luck!

how do i make it so that i can display mathematical equations with symbols like square root, pi, fractions, etc. in my programs?
i know of Microsoft Equation Editor, but i cannot find an SDK for it nor can i insert it as a component in VB.NET. it would also be nice to do this in C++
if any of you know how, or know of other equation displaying packages available, please reply or send me an email

You write a layout engine for a word processor...
No, I'm serious. This is heavy layout stuff, not something I'd expect "just anyone" to get right.
If you just want to "do" this, I'd say your best bet is something like LaTex.

Hi, folks!
I want a combobox that will always display the same items regardless of where I use it, so I thought about having it be its own class, inheriting from CComboBox. Rather than remember to add the items to it in the InitDialog function for each dialog box I use it in, I want the list to fill itself when it gets created. That way, I can drop a combobox onto a dialog, then change its type from CComboBox to CMyComboBox in the class header and I'm good to go.
So, at what point in the combobox's creation sequence is the best place to put my loading function? (I'm hoping the answer will be something analogous to the InitDialog override for a dialog box class.)
(To clarify things a bit, I'm loading the list from a file, so I can't create the list items in the Resource editor.)
Thanks!
Jesse

Why not override OnCreate for this? Let the base class handle the initialization chores and, on return, you will have a created window ready to accept AddStrings.

Hmmm... Well, that doesn't seem to work.
I used ClassView to add a Windows Message Handler for WM_CREATE to my new ComboBox class, but the function never gets called.
M$VC added the following to my header:
protected:
//{{AFX_MSG(CRosPartNumberCB)
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
//}}AFX_MSG
and the following to the source:
BEGIN_MESSAGE_MAP(CRosPartNumberCB, CComboBox)
//{{AFX_MSG_MAP(CRosPartNumberCB)
ON_WM_CREATE()
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
/////////////////////////////////////////////////////////////////////////////
// CRosPartNumberCB message handlers
int CRosPartNumberCB::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CComboBox::OnCreate(lpCreateStruct) == -1)
return -1;
AddString ("This is a test");
SelectString (-1, "This is a test");
return 0;
}
yet, a breakpoint on the above handler function never trips.
What am I missing here to get the connection established?

If you are using the control in a dialog, the WM_CREATE message is not sent to controls created with a dialog template. You have to override the PreSubclassWindow() function and do your initialization there. Or better yet, have an initialization function that you call from both OnCreate() and PreSubclassWindow(), that way your control will work both ways.

PJ,
Thanks for the insight! Yes, I was using the control in a dialog template. After overriding the function you mentioned, all is working as I wished.

I've got this MFC7 app I made in VS.NET and I can't get it to work right on a Win98 machine. I have a feeling I'm missing some files since VS.NET isn't installed on that machine and it is on my others. I have only tested it on WinXP so far and it all worked.
I'm using GDIPlus and MFC so I'm copying these files into my app directory: gdiplus.dll, mfc70.dll, mfc70u.dll, msvcr70.dll. I made a little setup project that uses the gdi, mfc and crt merge modules to copy these files in.
The app runs, but one of the list boxes (CListBox) is non-functional and another one works fine. Also, it adds a system tray icon but that isn't showing up in win98 either.
What's the deal?!

Could it be a problem with the common controls? Try installing the latest version of Internet Explorer -- it the problem disappears most likely it is a common controls thing.

I need help saving large formatted text to an Oracle database. I am currently using CLOB data type in Oracle and a CRichEditCtrl control to stream the data in and out (StreamIn, StreamOut). I got an error message when the text is more than 124 lines (default Microsoft Word document setting). Please advise.
