hi all, i've aproblem with this function, i hope you don't minde to help me
CreateFileA(m_pstrAllUsersPath, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 128, NULL);
the m_pstrAllUsersPath value is "C:\Documents and Settings\All Users\Application Data\Avg9\update\download\avginfoavi.ctf".
It always return INVALID_HANDLE_VALUE although this file exist.
regards

Have you the rights required to open that file?

You should properly escape the path string, use:
"C:\\Documents and Settings\\All Users\\Application Data\\Avg9\\update\\download\\avginfoavi.ctf"
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

The file you are trying to open might be held by some other process with "no share" attribute. Or you might be passing a wrong file name. I suspect the first case.

When in trouble, read the manual. Better yet, read it before you get into trouble.
If the function fails, the return value is INVALID_HANDLE_VALUE. To get extended error information, call GetLastError.
There is no need for guessing, just call GetLastError() and you will know what gives.

Hello,
I have a dialog box that contains an ownerdraw listbox with imaghes and text I give the option to resizes the dialog box(by SetWindowPos),
such that not all of the listbox is appear ,
I changhed the vertical and the horizontal scrollbar properties to be true and they are appearing on dialog but I can't scroll them although the list box is not appear completely,
how can I cause the scroll bar to work appropriate ?
thanks

I just had what might be a similar problem, though it was just the horizontal scrollbar giving me trouble. I had to call SetHorizontalExtent, giving it the widest thing in the list in pixels.
Try calling that and see if it helps at least with the horizontal scrollbar.

Hi all,
please could i get some help on how to restrict writing to USB.
This is a complicated requirement i have, however this is what i need to achieve.
i need to restrict writing to USB. however writing can be done specifically to a folder and that too a specific file type.
i can use registry to block writing to USB, however this does not suit to the requirement.
hence i need some help on how to block writing to USB and allow only specific files to be written to one specific folder.
ThankYou.

You would need to write a USB filter driver which is not an easy task to do.

Try posting some of the code of your program (remember to put it within <pre></pre> tags) so we can see how you are doing it.

Hi all,
I have made a worker thread. I want to pass a integer as a parameter in my thread.
I am not getting how to do it.
Can anybody help me this.
Thanks in advance
|

A thread accepts a void pointer as its parameter.
If you want to pass an integer, you first typecast it as a void pointer and then typecast it back to an integer inside the thread function.
|
|
|
|
|
can you please explain me using a example.
|
|
|
|

Thread creation may look like this -
CreateThread(0, 0, Start, (LPVOID)1024, 0, 0);
Here 1024 is the value passed as parameter.
The thread function may look like this-
DWORD WINAPI Start(LPVOID p)
{
int i = (int)p;
return 0;
}
Here the passed in parameter will be available in the variable i.

It's been quite some time since I last used VC6 but I am currently working on an older project. I am sure there used to be a disable all breakpoints option but I cannot find it. It's not in the debug menu or the debug toolbar which is where I am sure it used to be. Anyone know where it is?
|
|
|
|
|
Tools > Customize > Commands tab. Choose Debug from the drop down box. On the right pane select the icon with two hands.
|
|
|
|
|
|
Alternatively, Alt+F9 to remove all breakpoints.
|
|
|
|
|
In that case better use Alt+F9 and Alt+L in sequence and then return key. You don't need mouse to write code

Doesn't work in the Swedish or German version... otherwise totally agree. 
|
|
|
|
|
WOW! that's news to me. Why so, is it a bug or does 'L' map to something else?!
PS: Searching the web was a chore so I am asking you.
|
|
|

|
Alt+L works because of the button text in the English dialog window (underlined letter L), right? My first guess is that it's not a keyboard accelerator and depends on internationalisation (different button text often means different key combination to activate that button).
