Do you actually need to do mathematical operations on this number, or is it just to store it. If you just need to store, then you could put it in a string or char array

Do you want to store a telephone number or similar why don´t you use a string or as mentioned a selfwritten class, where you can define some operations as comparesion.

Hi,
I cant understand this: in my program, I have to support multi-language resources. So I did DLL for each language I need to support. The resources ID are the same in every DLL, only the content vary. But I cant understand, why does my program load dialogs from DLL, if I this DLL only link from LoadLibrary. The same case is with menus and toolbars...How can the program recognize which library to use ?

All resource-related functions (DialogBox, LoadString, etc...) in Win32 api use HINSTANCE parameter. You need to load your .dll with LoadLibrary[Ex], store the return value and pass the handle to resource functions.
If you're using MFC, AfxSetResourceHandle takes care of passing instance handle to Win32 api. In fact, MFC searches resources through so-called resource chain. You can have common resources in .exe and language-dependent in .dlls.

Hi,
I have a property sheet embeded inside a form view and I would like to validate the controls on an individual property page before the selected page changes.
I have tried to handle this in OnKillActive but this gets called when other controls on the formview are selected. I only whant to validate on a page change.
Has anyone got any ideas
Cheers,
Will

Hi,
I have this problem: My program has to find out, if ip address of currently connected client (my program figures as server) is equal to one from defined regular expressions. These expressions can look like this: 195.200.69.*
195.200.?5?.85
195.*.56.56-59 (interval)
Dont you know how to solve this (I think rather logical problem) as elegant as possible. Maybe there is already some class to represent work with regular expressions, but I must support *, ? and - wildcards. Will anybody help please ?
Any suggestion will be appreciated.
Celebrate Mr. Cesilko!

how can i use a switch structure to compare words? (since switch does not work with CString, char* or char[])
Any help would be appreciated
|
|
|
|

seeing as switch does not work with CString, char*, or char[], you can't. You'll need to do what the compiler does internally in any case, a string of if else statements.

'String of if eles statements' isn't always used. Compiler can build a lookup table with addresses of code fragments to execute appropriate 'case'.

Hello,
I have some theoretical questions about the hooking stuff, I know that different processes might have different premissions, now lets call two processes #1 and #2, while #1 has only read premission from the HD and #2 has both read/write premission. (it's only to get the idea), now lets say there is a global hook procedure which writes log file to the HD, the question is wether it will act differently for process #1 and number #2, and if so, maybe #1 can use this trick to write file, which it has no premission to.
I hope I'm clear, because even I don't really understand what I wrote. 
thanks,
Guy.

As long as your global hook procedure is implemented
in a dll, the library is loaded into process, and
shared code inherit process properties, so, the process
without permissions, will be unable to write to disk.
What you really write about is the inheritance of process permisions
over dll's which process use.
Hope to give you an ideea.

Short answer: No, your process #1 is not able to write to file via the Hook.
Long answer:
Global Hooks are implemented in DLLs and loaded into the target process address space. The target process may contain more than one thread. Therefore the hooks code is executed in the security context of the thread that triggers the hook event. Things are even a (small) bit more complicated: If the WriteFile() succeeds depends on the token of the current (calling) thread, which is usually the process' token, but may be also an impersonation token.
This is the point another thing comes into the context. If the hooks code is always executed in the secuity context of the target process/thread, one could use this to insert code into processes with a higher privilege level (and e.g. make himself a member of the Admins group). Therefore it is usually not possible to install a hook in a "foreign" process (a process that runs in another user context, like services or processes started via RunAs).
According to MSDN a process could enable hooks of foreign processes "running on the same desktop" by opening the desktop with the "DF_ALLOWOTHERACCOUNTHOOK" flag. (The complete thing is a bit underdocumented in MSDN and I don't understand what a "process running on the same desktop" is, because, once again, it's the thread that is attached to a desktop - not the process.)
Hope I did not totally confuse you

Errr... thanks?!?
just kidding, in fact that what I was getting to that you can improve your premission state. well, it's interesting to hear about the account thing, but if I use two processes at the same account and one has less premmission by definition of the programmer at the creation time, I think it will be able to get the maximum premissions of the user that is now logged on.
I guess we will have to try and learn
thanks,
Guy.

Oh, seems I have confused you a bit by all this security stuff 
Sorry about that, but here we have to go on

Uh, oh no I am a bit confused. The thing is, there is no "limitation of permissions at creation time". NT security is completly user related. Of course, the programer decides which kind of access rights his program code utilizes e.g. by simply not doing any write operations. But thats not a limitation of the access rights of the process which executes the program.
It's simply the difference between beeing forbidden to do something and just not doing it. Only the user context of the process defines what is allowed and forbidden.

Hi all,
I have a basic question regarding size of struct.
I have following code:
struct MyStruct
{
int PortAddress;
char onmask;
char offmask;
int *PortData;
};
void main(void)
{
struct MyStruct m_struct;
int* pInt;
printf("size of char = %d\n",sizeof(char));
printf("size of int = %d\n",sizeof(int));
printf("size of int Pointer= %d\n",sizeof(pInt));
printf("size of MyStruct= %d\n",sizeof(m_struct));
}
Out put looks like:
size of char = 1
size of int = 4
size of int Pointer = 4
size of MyStruct= 12
Now my question is why I get the size of Mystruct = 12 instead of 10 (4 + 1 +1 + 4) ?
thanks for help
regards

I try to intercept some message coming from a menu item.
I get correct values for nID and nCode when rolling over the menu item. When clicking, nID points to something that seems unrecognizable.
How should i get the click?

I think nID is the handle of the menu...
|

Is there any special requirement that stops you from using message map and handler for nID?

Yes, it is. I have to handle dinamically added menus, in the main frame's queue. Thus, i cannot provide message map entries because i don't use static menu structure. Also i have to filter the menu messages before they reach the view's queue.
Anyway, PreTranslateMessage solved the problem.

Assuming that your dynamic ids are located in predefined range, you may also use ON_COMMAND_RANGE.
