Check your return values - you're not checking whether the fopen() calls succeed.
Run the program in the debugger (F5) and when it crashes, the debugger will show you exactly where it's happening.

The thread 0xE8 has exited with code 0 (0x0).
The program 'C:\p123123123123123123\asdasdasd\installer\Debug\installer.exe' has exited with code 0 (0x0).
however the .exe file still gives me the same error.

I suspect it's your call to GetCurrentDirectory, which will return different values when you run in debug mode versus executing the .exe directly, through explorer or a shortcut icon. I could be wrong of course....

I run this exe from the explorer in "C:\p1231231\asdasdasd" without any problems. if i add a 2 to the first directory "C:\p12312312\asdasdasd" I still have no problems. However if I changed it to "C:\p12312312123123123123\asdasdasd" I get a crash. I do not understand.
Does the other ppl who r trying to help me also receive this POST? or do I have to reply him as well with the code also. Sorry but I'm noob in this.

char *cur_dir;
cur_dir=new char;
GetCurrentDirectory(512,cur_dir); Not sure if this is causing the crash, but that code is wrong - you're only allocating one char but you're telling GetCurrentDirectory() that you allocated 512. This is a buffer overrun bug and GetCurrentDirectory() will end up writing to random memory, which may be corrupting the CRT enough to make fopen() crash.
(BTW, everyone can see the whole thread, this one reply is just fine, welcome to CP  )

hrmmmm, i feel so dumb !!! ty ty ty
i think i need eyeglasses or something. that did solve the problem.

No, but they'll see it if they are interested.

Yeah, that's pretty weird. I've tried a bunch of different folders and they all work for me.

I assume that the code where you get the current directory name looks something like the following:
char szBuffer[512] = "" ; // <- this buffer is big enough, right?
GetCurrentDirectory(512, szBuffer) ;
I agree with Mr Dunn that there must be a buffer overrun going on somewhere. Such overruns often don't occur when running in debug mode, then rear their ugly head in a release build.

yes, ty, the problem was solved
char *cur_dir;
cur_dir=new char[512];
strangely the overflow only occured when strlen(filename) > 39/41 characters long, which mislead me on where to look for the error.

what is the simplest way to get the output of a cmd window into a dialog?
mfc VC++ 6

CHeck out this article[^], the sample code runs a console app and reads the output.

In my memory,i think PIP2 can catch the output of cmd app's message.....

I would need to have a different spacing between lines in a multiline edit box, but I can't find anything. I can change the spacing between character, but not lines. Is there anything that could do this?
|
|
|
|

Besides rolling your own edit control, you could use a ES_MULTILINE Rich Edit (2.0+) control and
set the line spacing with the EM_SETPARAFORMAT message using the PARAFORMAT2 structure.
It may be over-kill for your needs but it works
|
|
|
|
|
Seems a bit too much to go now and change all the Edit controls to Rich Edit and so on. So I guess I'll leave everything as it is and no line spacing this time 
|

It's actually not too bad since Rich Edit controls work with the same messages as standard
edit controls. They sure have alot of stuff you may not need though!

I have a problem with passing function pointer as lParam. I get an error message like that: error C2440: 'type cast' : cannot convert from 'void (__thiscall Screenshots::* )(void)' to 'LPVOID'
how to fix that? 
Screenshots::Screenshots()
{
void (Screenshots::*ScrLoopPtr)(void);
ScrLoopPtr = &Screenshots::ScrLoop;
hookHD = CreateThread(0, 0, mThread, (LPVOID)ScrLoopPtr, 0, 0);
}
thanks for help
|
|
|
|
|
Whats the purpose of this line?
void (Screenshots::*ScrLoopPtr)(void);
Is your Screenshots::ScrLoop function declared as static?
Try this
typedef void (Screenshots:: ScrLoopPtr)( void );<br />
ScrLoopPtr = &Screenshots::ScrLoop; <br />
hookHD = CreateThread(0, 0, mThread, (LPVOID)ScrLoopPtr, 0, 0);
|
|
|
|
|
it was simpler than i thought
ScrLoop was not static so i declared it as static and passed its pointer like that CreateThread(0, 0, mThread, &Screenshots::ScrLoop, 0, 0);

Hi
I am reading some documents about win32 programming.And try to understand its event procedure.
For windows controls which i added to my application.When an event occurs windows add a msg to its msg tail.But also send WM_COMMAND msg to my application so i can do something when that event occurs.
For example for button click event:
Message:BM_CLICK
Notification:BN_CLICKED
(I hope i am right until now)
But i looked other controls mesg and notification lists.They don't match.I mean there is not notification for every message.
For example combobox have CB_ADDSTRING mesage, but it does not have CBN_ADDSTRING notification.
But why?
What is the concept for notification and messages, what is the differnces between them?
I hope i can explain my question well, i am trying to understand win32 event procedure fully when an event occurs.
I am looking for your answers.
Thanks..

One more question.
When an event ocuurs for example button clicks.
Which one is first doing by OS.
Notification or msg?
I mean, first windows put msg to msg tail of button control and put WM_comaand msg to my application.Or reverse order?Which one is first?
|

The best thing to do is use spy++ (comes with VC6) to watch the messages in a window. In Visual Studio, click 'Tools' from the menu and then click spy++. Use this tool to first find a window, then watch it's messages. You can start clicking buttons in the window to watch which messages are being sent and recieved.
|

I'm not I follow your logic "When an event occurs windows add a msg to its msg tail". But here is the basic principle.
A message is more like a command. A BM_CLICK tells the button to click. A notification only occurs if something meaningful happened. The button was clicked, you need to know about it so a BN_CLICK is sent. You chose a bad example here because BM_CLICK tells the button to simulate a click, which you already know about since you sent it.
CB_ADDSTRING will tell the combobox to add a string, there is no notification because you already know a string is being added ( YOU added it ). But, if the user clicks an item, you need to know, so the combobox will send a notification to you.
Most messages you will deal with ( the command type ), are what the OS wants your application to do. WM_PAINT to display itself, WM_CLOSE to close, WM_DESTROY to jump of a cliff and commit suicide. All the window controls will process the same messages, but this is hidden from you because windows does it for you. But for example, if you click the minimize button in your app, the desktop window will need to be notified so that it can repaint itself, so a WM_SYSCOMMAND will notify the parent.
Understand?
