It uses memory from the global heap. It's no problem to alloc 50MB with malloc()

Yo.
How can I paint on a CDialog wnd a *.gif picture, without using CHtmlView.
I want *.gif cause' I can use pics with transparent bkgrnd.
(I know howTo with *.bmp, that's not the case)

You'll need GDI+ or a third party library to use gif, and if you do, beware the evil Unisys license. Otherwise, the MSDN explains how to do transparency masking on the fly, I have an article up at the WDJ site on how to do it as well, or if you're not targetting W95 you can use TransparentBlt ( you'll need do download the SDK if you don't have it ).
If you use GDI+, you don't need GIF, it also has transparent drawing built in.

What's the proper way of assigning a STL string value to an MFC CString or vice versa? Can you do that?
|
|
|
|
|
CString str;
std::string x;
str = x .c_str ();
x = (LPCTSTR) str;
That should work.
|
|
|
|
|
CString mfcStr;
string stlStr;
mfcStr = stlStr.c_str;
stlStr = /*(LPCTSTR)*/mfcStr;

Hi,
I am newbie writing a small SHAREWARE program.
I want to control my software with time limts.(Ex: 30 days, or 2 weeks or Turn off some features after 30 days)
How to accomplish that?
I appreaciate any information regarding this.
thanks
Ravi

You can get the current time at setup and save it to file or reg and to check if in time limited range get the current time at program runtime substracted by the time in the file. The result should be less than the time limited range. All time will be in the format of the number of millseconds since 1/1/70(i think it 1970) and the results is just in millseconds.
Real World Coding:
POP& BuyAPop(Money ADollar){...};

Looks like good idea.
I have one more question, as I am exploring other options too..
How some shareware programs work with checking serial numbers logic. Ex: If you enter the code, it will go and check at their website, is that number legit or not.
thanks

Most shareware progs that ask you to enter a regcode have some kind of algorithm to check if its a valid serial number. Actually ther's not much pointing in writing a complicated function because for a cracker it just adds to the fun.

Why not, I have made some pretty complicated algoritms for my serial numbers. Why make it easy for the crackers?
If they wanna crack one of my applications, they have to be good and work for it.

They'll just crack out your serial-number algorithm.
If I had to write a demo-version I would write one WITHOUT the limited code so that nobody could crack it but order

I'm having difficulty getting my VC6.0++ ATL->ActiveX Server Object EVENTS to show up in Intellisense (all other methods show up).
*I made sure ConnectionPoints were checked when i made the object, so I have an _IFunkyEvents Implementation thingy
*I right clicked on my "CFunky" and clicked "Implement Connection Points", which made a CProxy_IFunkyEvents<class t="">
*I added events to _IFunkyEvents, I compiled before I tried to "Implement Connection points", and then I did it, and I would recieve an error about:
;;CONNECTION_POINT_ENTRY(IID__IFunkyEvents)
*I changed IID__IFunkyEvents to DIID__IFunkyEvents and that stopped that error... <shrug>
Is this a "common stupidity thing"? Any clues as to what I'm doing wrong when I'm going through those wizards?
SHABBA!!

Microsoft has documented that as a bug in the wizard.

You need to handle the "Navigation Error" from DWebBrowserEvents2.
You should write a BHO for this purpose

Can anyone tell me how to hide or show a toolbar on the MainFrame window from another thread. When I do something like:
frmMain->m_canvasToolBar.ShowWindow(SW_SHOW);
the function returns FALSE. And when I try to use:
frmMain->ShowControlBar(&frmMain->m_canvasToolBar, TRUE, FALSE);
the application crashes deep down inside the MFC core.
|
|
|
|
|
I would post a user defined message from the thread to the main frame.
In the main frame, have a message handler that calls ShowControlBar();

It may be that your sole purpose in life is simply to serve as a warning to others.

Hi all,
What is wrong in this code, for exception handling ?
try
{
m_Database.Open(........);
}
catch(CDaoException *e)
{
e->ReportError();
e->Delete();
exit(0);
}
Does i must define m_Database as pointer ?
Please help me !

Take a look at the call stack and try and figure out what line is causing the crash.
