I am completely frustrated. I am running Microsoft Visual C++ vers 6.0 and have created an application using the Microsoft App Wizard file/new, MFC Wizard(exe) module. It generates all of the "skeleton" code that will support menues, dialogs, etc. I am using it as: a Single Document, no Document/View architechture support, no document support, no features, no project style, pretty much a default application. The App Wizard generates the workspace and when I compile and run, I get two link error lnk2001, unresolved external references for On_Cancel() and OnOK(). I have tried all resolutions but still get the errors. What am I doing wrong and how does one find out where the variable are and why they are unresolved references. Any suggestions will help. Thanks at sid_kraft@msn.com.

That's odd. Are they on a class that has been generated ? Are there calls to On_Cancel and On_OK in the code ? Perhaps you can track down what is making it look for those calls, and perhaps you have to delete some code, or just add definitions for those methods to the class in question ?

Anybody know how to store stuff in Windows Protected Storage? Outlook does it for email passwords, and IE stores autocomplete passwords there. But I have no luck trying to figure out the API via Google or MSDN. So am I missing something obvious, or is this an undocumented feature?
Thanks,
Mike

LsaOpenPolicy, LsaStorePrivateData are your friends.
Of course, this is WinNT and variants only, no Win9x/ME stuff here!

Thanks... Although I saw this in the function docs: Do not use the LSA private data functions. Instead, use the CryptProtectData and CryptUnprotectData functions.
I am currently using CryptProtectData, but that doesn't actually store the data anywhere. So I wonder why the rather strongly-worded discouragement 
Thanks again,

Beats me. After all, DCOM relies on the LSA private data functions at the moment, as passwords are stored in there. Of course, you could CryptProtectData something, and then store it using LSA 
I recently saw gadgets which combine a CF card reader and fingerprint scanner, or in one case a HDD and fingerprint scanner. That's my idea of security, although to be really safe, I'd want the scanner to be able to measure the O2 level in the finger as well, to be sure it wasn't chopped off. Paranoid? Me? Who's been talking??

After reading that several times, I would say start with requirements and specifications.

Hi, all.
Is there any convenient way in MFC to see if a user can write to particular directory, other than opening a file for writing in that directory and catching exception if writing is not allowed?
Best regards.

But wouldn't that be the most assured way?

Of course, it would. But maybe there's some means, made especially for that purpose?

hi all,
I am using eVC++ 4.0 for windows mobile programming and I have a problem:
I want to include a browse for folder dialog in my application but when every I attemp to link the linker gives me an unresolved external symbol problem.
I googled for the problem and most sites say that this API is not implemented in the ceshell.lib.
Anyone used this function successfuly with eVC++ 4.0, 2003se sdk??
if not, are there any easy alternatives?
Thanks

What symbol? Are you linking with shell32.lib?

no, I am programming for windows mobile, so I link ceshell.lib.

Does that DLL have an exported SHBrowseForFolder() function?

well, thanks david for ur replies.
In my search through the net, I found that there is a documentation fault in MSDN, MSDN says that this function is supported under wince 4.0 and above, actually it is declared in the header file, but it is not implemented in the .lib file - this is according to many sites on the net. So, it is not a linker problem.
Is there a simple alternative?

so i got a pointer
void *p;
and a structure
struct d{
blah....blah..
};
d st;
and i use it with
memcpy(p,&st,sizeof(d));
so my trouble is:
after using memcpy i need to advance the pointer with sizeof(d), so i can copy another one.
tryed p+=sizeof(d) but got :
error C2036: 'void *' : unknown size
help pls .

If you want to use the pointer that way just declare the pointer as char* instead of void *. You could also just cast the pointer variable to char* if you really want to declare the pointer as void *.

is there another way to shift it?
|
|

have you noticed that in your sample, p is not assigned, so memcpy() is writing nowhere (and there, will crash in a memory violation access) ?
do p = new d; first...
|
|
|
|
|
p is used in a buffer lock in DirectX
Vertexbuffer->Lock((0,sizeof(g_cubeVertices),(void**)&p,0);
so its good :P

Since you will probably be doing this in an array (I assume this is for DirectX vertices?) if st is an array of d's instead of single ones, just call it this way:
d st[100];
memcpy(p, &st, sizeof(d) * 100);
