I have a query releated to obtaining license number for executables on Windows platform.
On Windows, most of the applications will have a licence number associated with them. (for ex: if we go to explorer and obtain properties for an .exe, it might have the license number listed out).
I want to determine this license number programmatically.
This information is not available even in the program header of the .exes. Please let me know if there is any other source of retrieving this information (either registry or some API or some other way out....)
Thanking you in anticipation

You need to look at the VerQueryValue() API.
Its documented on MSDN. Complete with a trivial code
sample. You'll need to tweak it slightly to get what
you want

I have always thought that a static library was just like collection of .obj files.
However, I recently tryed to seperate a bit of functionality from my app by, moving the files out and building them into a static .lib.
My problem when I do that is I now get all sorts of library conflicts when the main app links.
Is there more to static librarys than I realise?
|
|
|
|
|
Did you delete the .obj files of the files that were put into the static lib project?
Could you be a little more specific as to what library conflicts you are getting.
|
|
|
|
|
The conflicts were all standard librarys, like libcd.lib and libcmtd.lib, and some of the afx ones. I can't remember the exact names.
Thinking about it some more I think a possibility maybe is that it could have to do with some of the afx includes explicitly linking. Do they do that? If thats the case, then how do I get the static library to link with the same librarys as the main app, and if not ...
|
|
|
|
|
Ok, I've just learnt something new about VC. You can set the library type you want to link under C++/Code Generation.
Changed all my dependant libraries to the same as the main app and it works perfectly...

I have to build a small database that will be used by a VC++ application and I don't know a lot about creating a DB under Windows and interacting with it. I also need to use SQL Server and not Access. Does anybody know a good tutorial for this kind of situation because MSDN is really poor on the subject (only uses those crapy .mdb)
Thank you for your attention.

I have tried RegSaveKey to export HKCU and all its subkeys. In regedit, I export and got a text file. But in RegSaveKey, I got a binary file. Can I get the text file programmatically?
Thanks all!!!!!

I'd like to get some feedback from you guys about the best/proper way to use bitmasks.
I've seen them used in several ways, the most common I think is to do something like
#define BLAH 0x0001
So I was wondering what is the proper way to use them.
I've seen people use decimal number, hex numbers, ascending, decending, short, long and the list goes on and on.
So let me know what you guys think is a good strong coding practice to get into the habit of.
Thanks!

Whatever representation you use, they should be const variables rather than preprocessor macros.

Hi,
I want OpenDlg with out using any MFC ( like CFileDlg etc)
OPENFILENAME ofn;
memset(&ofn, 0, sizeof(OPENFILENAME));
ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hwndOwner = hwnd;
ofn.hInstance = AfxGetInstanceHandle();
ofn.lpstrFilter = NULL;
ofn.lpstrCustomFilter = NULL ;
ofn.nMaxCustFilter = 0 ;
ofn.nFilterIndex = 0 ;
ofn.lpstrFile = lpcszFile ;
ofn.nMaxFile = MAX_PATH ;
ofn.lpstrFileTitle = lpcszFileTitle ;
ofn.nMaxFileTitle = MAX_PATH ;
ofn.lpstrInitialDir = NULL ;
ofn.lpstrTitle = NULL ;
ofn.Flags = OFN_EXPLORER|OFN_FILEMUSTEXIST|OFN_HIDEREADONLY ;
ofn.nFileOffset = 0 ;
ofn.nFileExtension = 0 ;
ofn.lpstrDefExt = NULL ;
ofn.lCustData = NULL ;
ofn.lpfnHook = NULL ;
if( !GetOpenFileName(&ofn) )
I did not the openDialog.
can any body tell me where was the wrong?
Thanks,

Hi everybody!
Situation: using a browser control to display html-pages hosting activeX controls.
Problem: tooltips doesn't work for all controls hosted in the html page.
Does anybody know how to enable/display tooltips for activeX - controls inside the html?
What I know is that every object inside the html has the IHTMLElement interface which has the property "title". This works fine for windowless controls but it seems to fail for "windowed" controls.
Any idea?
Thanks in advance!

i will be writing a client program for a VOIP product.
it requires me to enhance my Visual C++ GUI through skins.
My base GUI will be written in VC++ but the main dialog
will be skinned to enhance the appearance.
my colleague recommended ActiveSkin.
i have problems integrating it with my VC++ programs
any advice for VC++ with skin.
any other issue is that i may have to provide changeable
in the future.

Is it possibl to initiate a graphics mode in a standard C++ console application? If it is and you have before, i would praise you if you took a moment to copy\paste the source in a response to this message. I have Visual C++ 6.0 Standard Edition.
|
|

|

No, you can't initate graphics mode in a console application (which is what 32 bit VC creates). You can do so in a DOS application, but you would need a DOS targeting compiler.
You'll need to use standard Windows GDI, WinG, or DirectX.

Its been a while since I've used it, but I remember Allegro was a pretty good graphics library.

I have a function that keeps returning a value. For some reason, when I have at the end of that function
cout << "." << endl;
everything works, I get a new value each time. If I leave this command off or type cout << "."; I get an error in my calculations.
Several sources say "the endl command outputs a newline character and flush the stream". How can I "flush the stream" without creating a new line?
Any response any one can give me will be greatly appreciated.
Sincerely,
Erich J. Ruth

I really appreciate your response. I have gotten responses
from you before and they have always been helpful.
For some reason, I still can't get my code to work. I managed
to reduce it to the following error. If I type at the end
of my function
cout << "." << endl;
the code works fine, but I get along list of periods before
I get the answer. If I type
cout << ".";
or
cout << "." << "\n";
or
puts("");
or anything that doesn't have the endl command, then my
calculations are way, way, way off. It does not make any
sense to me why is works with endl. In a book I read,
it says endl "flushes the stream", but the command
cout.flush(): doesn't "flush" anything.
I am going nuts! Please any response you can give me will
be gretly appreciated.
Sincerely,
Erich J. Ruth (an overworked graduate student)

Let me go back one step and ask, do you know what flushing means? Standard output is normally line-buffered, so that any text sent to cout is not printed until an end-of-line character ('\n') is printed, or the program exits.
Flushing cout means that any text waiting to be printed is immediately printed.
Since the endl manipulator does an "end of line", it flushes cout. Calling cout.flush() does the same thing, just without going to a new line.
If the presence/absence of a cout method call is affecting code earlier in the function, I'd guess that you have a stack or buffer overrun somewhere in your code.
How exactly is your code going wrong when you don't have cout << endl;?
