Hi,
I'd like to make my CFrameWnd subclass not resize any smaller than a certain size. Everywhere I web-search, I see that the suggested way to do this is:
void CWndDerived::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI)
{
// set the minimum tracking width
// and the minimum tracking height of the window
lpMMI->ptMinTrackSize.x = 200;
lpMMI->ptMinTrackSize.y = 150;
}
I type this into my (very simple) app, and set a breakpoint at the start of this function. It is never called.
Is this method still valid? (under Visual Studio 2005 c++)
Thanks,
Max

Are you sure this class window is window you are trying to resize ?
A quick test in simple SDI app, shows result as expected.

Can you tell me exactly what you did? And are you in Visual Studio 2005, C++?
I did:
SDI: doesn't work
SDI + DocView architecture: doesn't work
SDI + Split Window: doesn't work
Are you setting anything special? Or adding more than just the
OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI) function?
Thank you,
Max

Have you seen David's[^] reply ?
Are you sure macro ON_WM_GETMINMAXINFO is there as messsage map entry ?
|

I do not have a message map entry. How do I add one for ON_WM_GETMINMAXINFO?

As has already been mentioned, use ClassWizard.

Did you use ClassWizard to add it? Is BEGIN_MESSAGE_MAP() correct?

All I did was cut and paste the code into MainFrm.cpp, and add the function to the class declaration in MainFrm.h.

Then you are missing the entry in BEGIN_MESSAGE_MAP(). It's fine to add the actual code (i.e., that which is in between the curly braces) to your functions/methods, but use ClassWizard to add the prototypes.

How do I add the message map entry using a wizard? Do I use the "Add Member Function" wizard?
Thanks,

Ctrl+W, unless you are using VS200x. Otherwise, see here.

Looks like you're missing a #include.

Seems that would have resulted in:
error C2065: 'assert' : undeclared identifier
instead. With VS6, __MODULE__ is not even part of the assert() macro so I'm not sure what to even suggest.

Where did you get the __MODULE__ predefined macro from?
If you right click on "assert" and choose "Go to Declaration" then what file do you end up in?
It should be assert.h ( which you should be including with #include <assert.h> ).
In the RTL code with VS2003, it only uses these macros: __FILE__ and __LINE__

ya exactly,
assert(0);
and printf("\nHere %s %d \n",__FILE__,__LINE__); // for both statements I am getting the same error.
I included assert.h and tried but am unable to find the __MODULE__ predefined macro..
thanks in advance,
Ashok

Hmm I can't reproduce this at all. It works for me in console and GUI app builds no problems.
In Google search __MODULE__ shows up related to linux and python.
It's nowhere in the CRT or Platform SDK headers though.

I am using coledatasource::dodragdrop function for drag and drop. when i drag and drop between applications, i get an assertion in the source side in the following code
CCmdTarget::~CCmdTarget()
{
#ifndef _AFX_NO_OLE_SUPPORT
if (m_xDispatch.m_vtbl != 0)
((COleDispatchImpl*)&m_xDispatch)->Disconnect();
ASSERT(m_dwRef <= 1);#endif
#ifdef _AFXDLL
m_pModuleState = NULL;
#endif
}
can anyone help me solve this problem?
Thanks

C'tor of CString or assignement operator will take care of that.
e.g
CString csString(pCharArr);
or
Cstring csString = pCharArr;

Can you explain this?

Meaning that you can't do something like:
CString str = "Now\0is\0the\0time\0for\0all...";

Of course. Why would you think it was even possible?

Bt i able to forcefully insert the raw data in CString variable taking data in a loop up to its length but it creats problem wn the length of data is very large i.e. more tn 1000 because running loop up to this limit creats problem of hanging.I want to solve this problem. if any soln pls help me.
