After doing alot of research on the net I found that quite a few others are having the same issues and everyone suggested to use GetOpenFileName instead... I have implemented that and everything seems to be working fine.
Thanks for all the suggestions!

how to close or recycle FILE f_ptr after using it. e.g.
FILE *f_ptr1
if((f_ptr1 = fopen(textFileName,"w")) == NULL) {
...}
....
And how to recycle a array after use it within a program.
double data[10000];
....using it and finish use it
how to close or destroy it so reserve the memory

How about fclose()?

It's on the stack. What's to destroy?

fclose90 works, thanks! I mean in the heap?

Memory for data has not been allocated on the heap. The only way to free it up is to close the application.

Depends.
If array data is global then yes.

Hi, I use this way to capture the screen:
CRect lpRect;
CImage image;
CString strPath;
char chPath[256];
CWnd *pWnd;
int nBB;
//Get the window desktop
pWnd=GetDesktopWindow();
//Create a CWindowDC to hold the desktop info
CWindowDC winDC(pWnd);
//Get the size of desktop
pWnd->GetWindowRect(lpRect);
//Retrieve number of bits per inch
nBB=winDC.GetDeviceCaps(BITSPIXEL)*winDC.GetDeviceCaps(PLANES);
if (nBB<24)
nBB=24;
////////////////////////End///////////////////////////////////
Is there any way to send picture bits or make an array of pixels (A fast way)?
and I have know that there is another way to capture the screen using GDI+,
Can you possibly tell me how to do this?(Is it faster of above code?)
Thanks.

CImage::GetBits is just what you need.

How about GetFileSize()?

hi David
as I see GetFileSize() needs HANDLE to a file as a parameter , that means as i know I need to open the file for reading at least.
I need to retrieve sizes of files in loop. I did it by opening them and calling GetLength method, but it seemd ugly
<br />
for(...)<br />
{<br />
CFile file<br />
file.Open(path,CFile::modeRead)<br />
Length[i] = file.GetLength()<br />
file.Close()<br />
}<br />
Is not there any API like this for example?
ULONGLONG GetFileSize(LPCTSTR sPath);
or any more convenient way?
thank you

But does it work, and is it easy to understand both now and in the future?

There's also _stat().

Call ::FindFirstFile() will the path. Do remember to close the handle and all that if it succeeds.

Hello.
I'm trying to make a pointer to a method of instance of some class, like this:
<br />
<br />
class Foo<br />
{<br />
public:<br />
void DoSomething(int a)<br />
{<br />
......<br />
}<br />
};<br />
<br />
int main()<br />
{<br />
typedef void MethodCallback(int a);<br />
<br />
Foo *x = new Foo;<br />
MethodCallback *MC = (MethodCallback *)x->DoSomething;
}<br />
<br />
Works only if I change to static method.....
Any idia how to do this correctly ?
Thanks,
David

I believe you can't use what you have shown because of the objects 'this' pointer, thats why it works when you make it a static method.

Thanks people.
I needed to pass a function pointer to an API function, and because i did a class-wrapping, i needed to pass the class member-function, but it's not possible (thanks for clearing my eyes about the "this" pointer issue...)

Edit2 Sounds like nmake doesn't ship with just the compiler and linker tools - sounds like I have to download the SDK as well???
Edit I should note that vcvars32.bat has been run...
I've downloaded the free Visual C++ toolkit from MS web site: http://msdn.microsoft.com/visualc/vctoolkit2003/[^]
I have an application which uses NMAKE.EXE but it doesn't seem to exists with just the toolkit???
Do I have to download and install the Visual C++ IDE Express version???
Thanks

I try to run my application on one XP PC without visual studio 2005 installed, but failed, the error is like "cannot initialize properly" or "the application is not installed correctly".
So I try to run an application that is built from MFC wizards, without any change of the codes, the same problem happens to me, even i intall the framework 2.0.
One way to make it work is to compile it in MT mode, the other is install vs2005 on that PC, but I don't think these are the final solution, could anyone help me?
-- modified at 10:04 Thursday 13th April, 2006
The application is developed by vs2005 in windows 2000

the error might tell you that a DLL is missing.
provide these dll with your exe.

|
|

hi, thanks for your help.
I have tried copy all the dlls that i see from the dll dependency, but it can't work, as i know, in vs2002/vs2003, we only need to copy mfc70.dll and msvcr70.dll (maybe this name), but it looks not the same to vs2005. I even install the framework 2.0 actually.
