Pointers, as other argument types, are passed by value.
BTW you're code is messy, What are you trying to do?

sry about the messy code.
basically i am trying to do link list.
-i create a pointer to be the head_node in my main
-i pass by pointer the address of the head_node to the function
-in the function i create a new_node
-then i TRYED to set the new node address to the head_node via the passed in pointer
however it cant seems to work..
so does anyone got any idea how to pass in by reference???? thx

If you have to implement a linked list, then your structure must have pointer member at least(to address the next element or the end of the list).
Here you can find some info [^], there are a lot of good articles about here at CP (see, for instance The Basics of Linked Lists and Binary Trees).
I suggest some background about pointers too (have a look to a good C programming book).
Hope that helps.

This should probably be:
inc->a = newnode->a;

Hi,
I added ON_WM_CTLCOLOR message handler in the code. In OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
pDC->SetTextColor(RGB(255,255,255));
m_check1.DrawCaption(pDC,NULL,nCtlColor); //here for the second parameter which is LPCRECT what i should pass?
Will that work?

Try it out... If doesn't work, debug and post lines where it fails. If it DOES work... voilá/eureka/tantatachán

It didn't work. It disn't throw any error message but the caption text color is default black where i wanted this one to be in white.
HBRUSH DlgTest::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hBrush = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
pDC->SetTextColor(RGB(255,255,255));
//pDC->SetBkColor(RGB(230,250,210));
m_check1.DrawCaption(pDC,NULL,nCtlColor);
return(hBrush);
}
Where did i go wrong?

I don't know where the error is, but if you do want to have the caption of the radio button in a particular color, there is another solution (not so professional, but works). Empty the caption (nothing in ""), create a font with the color that you want and set the BkMode to transparent (if you dont want the letters to have a square background), then use the easy TextOut and write the caption manually

Did you have any compiler for check it?
|
|
|
|

Also how to count no.of folders/no. of files? in VC++ MFC.
|
|
|
|
|
Use ::CreateDirectory (...) to create a folder.
Or
::SHCreateDirectoryEx (...) to make a deep path of directories
As for counting files, you'll have to use FindFirstFile / FindNextFile to get a list of files/directories in a directory. You can check the WIN32_FIND_DATA structures dwFileAttributes for a FILE_ATTRIBUTE_DIRECTORY flag to see if it's a directory.
Good luck,
Iain.

there you go.

Or you can use of dlgdirlist for get folder and file names and count.

hi,
1. how can i capture a window (dialog) that is under another window?
2. also, is it possible to force a window to be display off screen, e.g.
i use findwindow to find the window, and then move it to offscreen for
display.
3. i'll then capture the window that is offscreen and put into another window
for display.
thanks.
br,

hey ,i met with a problem here~ i wanna find a code snippet which can read the "*.hgt" file
does anyone know where i can get this?
thanks a lot

The extension of a file is not the problem to read a file. You can use CFile/CArchive or any other possibility to open almost all extensions. The most important things are: Which saving mode has it? Binary, plain Text, UNICODE... and how is the structure of saved data (i.e. The first 30 Bytes is a header where 4 parameters mean 4 different things, then come 30 Bytes for a string, after 10x1 Byte for unsigned shorts, then a 10x20 Bytes to a matrix of...)
I want to mean... can you be a bit more concrete?
BTW, have you tried google?

first ,thank u for ur attention
yeah , you got the point~ "The most important things are: Which saving mode has it?"
and this is also where the problem lies ,thats i have no idea of whats the structure of this ".hgt" file
someone told me perhaps its NASA Shuttle Radar Topography Mission files
but i am still not sure

Then... I think ready code will be not easy to find, and without the structure and meaning of every data unit... practically impossible to code it. Good luck

hehe thank u very much all the same

if you don't know what the file is, why would you want to open it ?
you just have a file with that extension and just have the urge toopen it ?
|
|
|
|
|
hehe
all i know about this file is its a 3D map,i just have no idea what the structrue of this file is~~
however after i checked some websites i am partly sure its a Shuttle Radar Topography Mission file~
have u got any idea for this?

Hello everyone,
I have tried that even if I have multiple character pointer variables, if the content they pointed to are the same, they are allocated with the same value. So, I think from compiler point of view, the constant with the same content shares the single copy in memory?
Here is my test program in Visual Studio 2005.
<br />
<br />
int main (int argc, char** argv)<br />
{<br />
char* abc = "Hello";<br />
<br />
char* abc2 = "Hello";<br />
<br />
<br />
return 0;<br />
}<br />
thanks in advance,
George

That is a compiler optimization that you shouldnt rely on. /Gf on the compiler commandline tells the compiler to "place a single copy of identical strings into the executable file" and /GF "the pooled strings are placed in read-only memory".
