you can just bitmap the menu items and draw that instead, then they don't have to have the font installed.
So people who use large fonts? Maybe you could StretchBlit your menu items to the larger size so they look inconsistent and crap!

As for blind people, well, I guess they can't use it, but there are already so many applications they can use that I doubt it would make a big difference with a few owner draw apps out there.
So your application is probably being done better elsewhere, because I would suggest that people considering disabilities probably develop more usable software anyway.

You fail to appreciate the difference between an application that is primarily visual (ie, a lot of games), and an application that does not need to be visual at all (just about everything else). There are also people who have written games designed to be played as an aural rather than visual experience. Like this guy, in fact:

I didn't mention anything about StretchBliting, If the draw rect is bigger, you draw the real size and center it, and screw their large font settings.
I'm personally sick of the windows standard ui, and if it didn't take so much longer to do owner draw I would do it alot more.
As a matter of fact I will be doing it alot more even though it takes a little extra effort.

And that sums up entirely what is wrong with your attitude towards application development.
Maybe you should go read some books on user interfaces, like GUI Bloopers or The Inmates Are Running The Asylum.
Then you'll (hopefully) appreciate what an asinine, and quite frankly, appalling, attitude towards users you have there.

Currently im using an AutoRichEditCtrl where i would like to popup a ListBox containing set of items.....
Can anyone please help me...
thanks!

Hi,
Thanks for ur responses.......as the GUI is for different set of users who might not know english and hence the menu items should be in their own language...that is why i got to set new font for menu items....

Well, start here for some info that might be useful regarding character sets:
http://www.joelonsoftware.com/articles/Unicode.html[^]
In fact, IIRC JoS has a few articles that deal with developing for multiple langauges.
As long as you write your software with internationalization in mind (sometimes referred to as "i10n" or "i18n" - try googling those terms), you shouldn't need to worry about the specific fonts - as users in different languages will have the appropriate (unicode) font set themselves anyway!
I don't know of any developer that internationalizes their software in a manner that requires a new font being used instead of the systems default fonts.
HTH.
[EDIT] Just a thought - this still applies, even when the base operating system is set as English - at least on 2000/XP, as I seem to recall it's poosible to have multiple language bases installed. [/EDIT]

Internationalisation is always 'i18n' - there are 18 characters between the leading i and the trailing n. Internationalisation normally refers to the process of stripping out any language- or culture-dependent behaviour from the application, using the user's preferred language and culture.
l10n (not i10n) is Localisation (again, 10 characters between l and n), the process of taking an internationalised application and creating the appropriate resources to adapt it for a particular culture.
I seem to recall it's poosible to have multiple language bases installed.
What, you mean the Multilingual User Interface[^]? 
Microsoft's Global Development Portal[^] is a good start for anyone needing to write an international application.

I must have misread the 'l' in l10n as 'i' - I thought that the 18 and 10 might have had something to do with the number of languages being translated, 18 being a bigger and more complex job because you would include arabic, hebrew, japanese and chinese scripts, on top of a load of mostly straightforward left-to-right european dialects (being the original 10).

I posted this twice earlier, no responses. They got buried in a few pages of messages.
I have classes car, street, building and static world. The car, street, and building are created and modified and "exist" in the world object. Here is my post (after posting a question about how to create global class objects):
I declared a global static class world, and it was indeed available to all objects. Thank you for the advice. Eventually I'll do the singleton method. The only problem now is, for some reason, objects are incapable of modifying public attributes or calling public methods of the global class.
Lets go back to my example. Before I had the global class, when constructing a "building" object, I had to pass it the myworld object constructor. The constructor would initialize certain variables, and call some initializing member functions. It would also call a member function of the myworld object, that would essentially(on the myworld object side) just increment the building count attribute of the world class. Before and after building object construction, I cout'ed myworld object's building count. It didnt change.
Now, with the static global object myworld, the results are the same. Myworld just refuses to change. Building has been made a friend class to the world class. In fact, nothing is private in the world class.
Just to check my coding, I called world class member functions and modified building counts directly from the main function, and it worked. It just doesnt seem to want to be modified by another object.
Any ideas?

I suspect the reason no one has responded is that your problem is clearly not where you think it is. The situation you are describing isn't the case, a public method on a static object that you've tested from main can certainly be called and work from a member of some other class.
The real problem is something you haven't mentioned in your question, because you don't know about it. It's pretty much impossible to guess what that might be given your description.
Try boiling it down, come up with the smallest set of code that exhibits the problem that's plaguing you. Sounds like you should be able to express it in 10 lines of code or less. Don't use your existing code, cut it down to just an example of the problem - two classes, one static and one not.
Once you've done that, if you haven't already spotted the problem, post the code and I'm sure someone will help you.

Hello, everyone!
I want to get all the handles of opened msword windows on the local machine. And then send message to close them. I have no experience on FindWindow function before and the two parameters of this API make me puzzled. Are there some sample codes that I can make a reference?
BTW: Can I get the how long a specified window have been opened?
I am using VC++ 6.0.
Thanks in advance,
Geo

Is there a way to write up a littl C code in .NET or V6 and be able to look at the assembly code that it produced after it compiled?
|
|
|
|
|
Easy -- set a breakpoint at the beginning of the code you want to view the assembly for, execute the program in debug mode, then when the breakpoint is triggered, right-click on the statement and select "Go To Disassembly". (This is for VS.NET 2K3).

Michael's answer works fine. Alternatively, add the /Fa switch when you compile and .asm files will be generated that you can browse through with your favorite editor. I often find this more convenient.

I have a related question, I still haven't gotten around to using managed C++ code so I still no next to nothing about dotnet aside from it's java like qualities,
but i do know some assembly from reading books and so forth.
What format is .NET IL assembly in? is it MASM assembly, or a new type of assembly with different macros+syntax or what?
|
|
|
|
|
At a basic layout level IL syntax looks somewhat like other assembly syntax in that it is line based, has directives that start with a dot, labels at the left, then a short opcode, then arguments, typically rendered in aligned columns.
From there is goes on to completely unlike MASM (or any other physical machine assembly) in that the opcodes are stack based, strongly typed, and at a much higher level of abstraction than even CISC assembly. No macros or the like as ILASM is not designed to be written by humans so there's no purpose for such things.

Here is the whole code: I should of put it out here to begin with on my previous forum. I tends to generate an error c2783 on the find_index() call in the insert funtion. Is it the way I am sending the struct in the main to the insert fucntion? I don't know. Very frustrated with this.
I put void main() on the bottom of this page.
Thanks for the help.

Just a guess, based on the error code -- when you call find_index, you need to specify the template argument, e.g.: find_index<tractor>( ... ).
In many cases, the compiler will attempt to deduce the template argument based on the types of data you pass to it, but it can't in this case.

Hi,
I am newbee to VC++. I am basically C,C#,VB,VB.Net Programmer.
can anybody please let me know how to resize and reposition all the controls in the dialog in a dialog based applicaiton. actually I added a toobar, statusbar,treeview,listview and few buttons to the dialog. I want to resize and reposition the controls whenever user resizes the dialog window or maximize the dialog window. can anybody please give an idea to proceed or a sample to proceed ?
thanking you

I have a problem and need somebody to show me the light.
I am trying to pass a struct through a template class called table. I keep generating an error of c2783 and cant for the life of me figure out why or what is wrong. The code is directly from a text book. Here is the code that is generating that error.
template<class recordType>
class table
{
table()
{
size_t i;
used = 0;
for(i=0; i<CAPACITY; ++i)
data[i].key = NEVER_USED;
}
//MODIFICATION MEMBER FUNCTIONS
template<class recordType>
void insert(const recordType &entry)
{
bool already_present;
size_t index;
assert(entry.key >= 0);
//SET INDEX SO THAT DATA[INDEX] IS THE SPOT TO PLACE THE NEW ENTRY
find_index(&entry.key,already_present,index);
//IF THE KEY WASN'T ALREADY THERE, THEN FIND THE LOCATION FOR THE NEW ENTRY.
if(!already_present)
{
assert(size() < CAPACITY);
index = hash(entry.key);
while(!is_vacant(index))
index = next_index(index);
++used;
}
data[index] = entry;
}
};
struct tractor
{
int key;
};
void main()
{
table<tractor> ta;
tractor t;
t.key=44;
ta.insert(t);
}

Well, you didn't say where the error is happening, so I can only guess:
<s>template<class recordType></s>
void insert(const recordType &entry) Take out the redundant template there, you only need that if the method has different template params than the class that it's in.

sorry about not being more specific, but it seems to not like the way I am sending the parameter in the void main(). I will try your method and see what happends. thanks.
Also when I double-click on the error, it goes directly to the find_index() call in the insert function.
Such as: see the comment below.
void main()
{
table<tractor> ta;
tractor t;
t.key=44;
ta.insert(t);
}
