if you have for example a listbox
(1) Create a file with CFile or CStdioFile
(2)read items in the loop from listbox m_litsbox.GetText(i,str);
(4)write to file
(3) close file
And read MSDN and a good book

I dont know your code but maybe your problem is with hdc or a null handle in his class or i guess maybe your want to release sources from this class

No, hcd is correct.. I use CImage.load(...) and then I have problem with close - is not called any error, simply application is not close. I read that is some problem when is CImage in ActiveX - it is true?

|

if you read that some problem is with CImage in Activex why you use form it in ActiveX

because I read it now.. I need CImage in ActiveX.. I don't can rebuilt all application

Hello!
I want to create an WindowsFormApplication in VC++.NET (MSVS 2005)
which uses a TabControl.
In my Application the user should be able to create or remove tabPages,
so i`d like to have the Pages always fill the entire width of the TabControl!
I already tried with FillToRight, but that doesn`t worked...
So my Question is, why not? does FillToRight works only if there is a second row (mulitline true)? Or am i simple too stupid? I work on that for the last 4 hours!!!
Is there another way to set the Size of these TabPage "Heads" or do i have to write my own TabControl Class? (like http://www.codeproject.com/cs/miscctrl/flattabcontrol.asp)?
Pls can anyone help me?
Thx

Hi,
I am using OFN "Open" and "Save as" file dialogs. It appears in the corner of the screen. How can i bring it to the centre. As we are not creating it what can be the solution without customizing it.
Thanks in Advance,

Just use a hook procedure. In that procedure, respond to the WM_INITDIALOG message and center the window accordingly.

IMHO, you have to customize that!

Hi there,
I have a strange thing happening with calloc/malloc. Here is my code:
...
double *a = (double*)malloc(Na*sizeof(double));
double *b = (double*)malloc(Nb*sizeof(double));
double *c = (double*)malloc(Nc*sizeof(double));
...
The problem is that the two pointers b and c point toward the same address. Anyone aware of this problem and how to fix it?? (I'm working under .NET2003)
Thanks a lot.

There is nothing wrong with this code. Are you sure one of the pointers isn't being changed after the allocation? To guard againt this try the following:
...
double * const a = (double * const)malloc(Na*sizeof(double));
double * const b = (double * const)malloc(Nb*sizeof(double));
double * const c = (double * const)malloc(Nc*sizeof(double));
...
This makes the pointer constant but not the data it actually points to. With this in place any code (almost) which attempts to change the address of the pointers will not compile.
const is the programmer's friend.

Hi Steve, thanks for your reply!

Yes I'm sure, because I displayed the pointers right after the memory allocation. And I should add one thing: I can run the code on 2 machines, but only one crashes. I don't know, maybe some physical memory issue, but this PC is close to brand new. But what makes me think it's a coding issue is that I already had such problems by the past on totally different codes, not really able to fix them (maybe found some hazardous fixes when tweaking the compilation options, like for optimization).

How do you display that ? Post some code.

Sorry, the original code is like this (with calloc):
<br />
double *temp_radiale = (double*)calloc(grid->n_rad,sizeof(double));<br />
double *delta_temp_radiale = (double*)calloc(grid->n_rad,sizeof(double));<br />
double *avg_rad_energy = (double*)calloc(grid->n_rad,sizeof(double));<br />
then the code crashed, I guess because when the 3rd calloc tries to access the memory which has already been allocated by the second one, it crashes.
So I tried the following:
<br />
double *temp_radiale = (double*)malloc(grid->n_rad*sizeof(double));<br />
double *delta_temp_radiale = (double*)malloc(grid->n_rad*sizeof(double));<br />
double *avg_rad_energy = (double*)malloc(grid->n_rad*sizeof(double));<br />
<br />
#ifdef _DEBUGOOO<br />
printf("%x %x %x\n",temp_radiale,delta_temp_radiale,avg_rad_energy);<br />
#endif<br />
which actually displays the two identical pointers delta_temp_radiale and avg_rad_energy. But at the end of this subroutine, when I free, it crashes, obviously.
