I just opened the *.c file without loading any *.dsp or *.dsw.
Any pointers how to load the global folder?
Thanks.

Default Push Button

I have a property sheet. Before I changed anything, the default push button used to be the OK button.

Then I added three pushbutton controls the the property page. Now the first button I added has become the default pushbutton. In the UI, "Default Pushbutton" is not checked, however, running Spy++ confirms that this button is indeed being set to be the default pushbutton.

Why is that? How does MFC select which button it will use as the default? How do I change it back so that the OK button is the default?

Thats strange, because I had the exact opposite experience. I had to override several functions before I could get it to stop being the default button. You can try this tho:

In your CPropertyPage derived class override the OnInitDialog() function. Then include something like this in it:

<br />
BOOL CYourClass::OnInitDialog() {<br />
BOOL nRet = CPropertyPage::OnInitDialog(); // Call the base class init<br />
SetDefID(IDOK); // Set the default button<br />
return nRet;<br />
}<br />

I think it will work else where in your code too. Like in response to an update UI message would be a good place i think.

Do you know of any free tool which I can use to view my memory while I play with it...???

VC++ 6.0 memory window isn't cutting it...

I'm trying to watch char's get added and deleted and the memory view pane in byte hex mode just isn't working.

0064FE00  73 0D 00 00 00 00 00 00  s.......

The address column is really annoying...

Mainly i'd like to view strings with carrage returns while mucking around with the memory...?

Ideas...?

Thanx! Smile | :)

Linking Problems

Hello,

I am using VC++ 7.0 and I am having some trouble. I am trying to build a solution with multiple projects. All but one of the projects is set to produce a .lib (Configuration Type) as opposed to an .exe or .dll etc.

Some of the projects depend on and use functions from others.

The problem I am having is this:

Visual Studio seems to be automatically inserting library files into the (presumably lib) command line arguments that I did not specify. In other words, when I open the project fresh, those libraries do not appear in the command line. But then when I build, they suddenly appear.

The result seems to be that I am inundated with many of the warning LNK4006.

Has anyone had this problem or know what I am doing incorrectly?

Thanks
John

I try to write the LF(#10) char to a file using putc() but it automatically add the CR(#13) before LF. Is there anyway write only the LF char? Thanks.

I recently loaded Visual.net 7.0. I had been running an earlier version on another machine. I am now getting the following error message, the name of the program is CorpStrat.exe

'CorpStrat.exe': Loaded 'C:\CorpStratRes\CS2\Debug\CorpStrat.exe',
Symbols loaded.
'CorpStrat.exe': Loaded 'C:\WINNT\system32\NTDLL.DLL', Cannot find or
open a required DBG file.
'CorpStrat.exe': Loaded 'C:\WINNT\system32\KERNEL32.DLL', Cannot find or
open a required DBG file.
The program '[1812] CorpStrat.exe: Native' has exited with code 1 (0x1).

I am at a loss here. Any suggestions?

It only means that you don't have the Windows Debugging Symbols installed, and that's why it can't load the symbol files (.dbg) for the system dll's.

Don't worry, it's not an error. Smile | :)

You use the symbols when you watch your "call stack" window, then you can see the actuall function names, instead of just the offsets, in the windows dll's.

true symbolic variable ?

Maximilien8-Nov-02 10:01

Maximilien

8-Nov-02 10:01

Is there a way to have "true" symbolic variable ?

I'm pretty sure that I'm not explaining myself correctly, the situation is that I
have some #define that represent the type/state of some object.

#define STATE_UNDEFINED      0
#define STATE_SOMESTATE      1
#define STATE_SOMEOTHERSTATE 2

and I have a variable somewhere

int someState = GetState(); // which returns an int
// and later :

if ( someState ) // no == ...
{
}

The question, is there a way to make the state thingy really symbolic ?, not an int, char, or something else ? that I have to explicitly set and/or equal to the whole symbol ?

I'd like to prevent the user to think and abuse the fact that it's an int !

Max.

I believe that's one of the problems enumerated values solve:

enum State { Undefined, SomeState, SomeOtherState };
 
State state = GetState();

Is this what you're talking about?

Alvaro

It's better, but I can still abuse the fact that enums are int.

State myState = 0;

Not in C++ but in C it's working ! since I'm working with a mix of C and C++

Well, enums are the closest thing you'll ever get to symbolic manipulation in C++ I'm afraid.

If you want symbolic manipulation, please see the Lisp-family. It was designed for it, and it excels at it.

Hi everyone,

I'm new to C++ programming and i'm still learning, i was just wondering if its possible to execute a dos comman in C++? like the command FINDSTR, why i want to use this? because no doubt about it its fast when it comes to searching for a particular text in a file, and since my project is about searching i thought this is a good idea. Please if you know how kindly help me.

Thanks/Regards
