What is the syntax for forward declaration of a template class? I am making a DLL, I would like to forward declare the template class so that it can be "hidden" when you put the header in the application program.
Thanks in advance.

So I've been trying to get SendInput to send extended ASCII characters such as ä (ASCII 132) or à (ASCII 133) but have not gotten it to work.
Does anyone have any ideas as to how I can send extended ASCII characters to an input window via SendInput or some other function?
Thanks
Fred

A quick plug, Thanks to the guys that helped with the random double generator
I am reading in a file and parsing the data.
right now I am using the getline() function.
I am able to parse everything in the file with no problems.
Once I have the data I need to add it to a struct
There are 5 values on each line.
string,string,string,double,double
When I use the getline() function I everything is a string.
How can I convert the last 2 strings to doubles?
Is there a function that will allow me to get chars instead of strings?
Thanks,
sj
here is my function is case I didn't explain well enough:
<br />
struct TSimSignal<br />
{<br />
double Min[5]; <br />
double Max[5]; <br />
double Value[5]; <br />
char Name[5];<br />
char Unit[5];<br />
};<br />
<br />
<br />
<br />
<br />
<br />
void setInitialValues(TSimSignal &s){<br />
<br />
string name,unit,min,max,value;<br />
<br />
fin.open("mockData.dat"); <br />
<br />
<br />
for(int i=0; i<sizeof(s.Name); i++){<br />
getline(fin, name, ',');<br />
if(name == "STOP")<br />
break;<br />
getline(fin, unit, ',');<br />
getline(fin, min, ',');<br />
getline(fin, max, ',');<br />
getline(fin, value);<br />
<br />
s.Name[i]= name;<br />
s.Unit[i]= unit;<br />
s.Min[i]= (double)min;<br />
s.Max[i]= (double)max;<br />
s.Value[i]=(double)value;<br />
<br />
cout << endl << name<<" "<<unit<<" "<<min<<" "<<max<<" "<< value << "\n";<br />
<br />
} <br />
<br />
}<br />
<br />

I've created the default "hello world" program (console type program). The program works ok in VC++, but it doesn't as a stand alone. The program closes as fast as it opens (this is the release .exe stored in "My Projects"). I've tried various suggestions (such as adding "_getch()," etc...but I shouldn't have to do any of that. The program works in VC++ but not in the final released version. ANybody have any ideas?
Thanks

Console applications are applications that send all of their output to the console screen "stdout". When executing the program from an icon, windows will create a "command prompt" window for you, but upon completion of the program, the command prompt window will close. This is standard behavior.
If you want your program to maintain the command prompt window on it's own, add something to prevent the termination of the program. A getch() does the trick, as the program will not terminate until it gets some keyboard input from you. But when the program does termninate, the window closes. UNLESS you've set it in windows that command windows remain open.
The workaround, is to open your own command prompt window, and execute your program by typing the program name at the command prompt. This window will not close automagically.
OR change your program so that it is no longer a console application, and is a full fledged windows program with a real window.

Yes, I am trying to open it on the desktop. I was also trying to open another screen. I was thinking that the program should work by itself in windows since it works in VC++. I'm not sure how to bring up the DOS box you mentioned, I'm using Windows 2000 Pro.
Thanks, Dave

Start -> Run -> Cmd [enter]
You will have to manually navigate to the current directory where your program lives...

Here's a a really simple way of solving your problem.
Add the following code to the end of your main() function:
system("pause");
That's it. Now, instead of disappearing, your console window should display the message "Press any key to continue..." when running as a stand-alone.
The system("") functions allow you to add any DOS command to your program. For example, you could use system("cd") or system("exit") for various purposes.
Good luck, and remember to keep it simple.

Or you can put this at the end of your main():
int a;
cin >> a;
Your application will stay open until the user preses enter!

@yashraj1215: I do not want to criticize your answer, but do you know if it also works on a system that is not based on DOS anymore, such aus Win XP? I've got 98SE and imagine it to work, but does XP accept those DOS system calls?
@Scolinks: What if the user enters something like "n" or "No, no, no!!!!!!"? Although it might work (I've compiled a test program, run it & got no errors), maybe it's just luck that this is accepted?

Unicode is the super character set -- it represents every character in the world (kinda)... it does so with "characters" that occupy 2 bytes each.
Check out officialy UNICODE website, and this page which explains UNICODE in every language:

Someone told me that I the reason I need to go in VC++ to "project/settings/links/output/entry-point" and enter wWinMainCRTStartup is because I'm using UNICODE. I'm lost on this. Could someone please explain.
Thanks

What was your original problem? This wasn't the link error to WinMain@16?
What version of VC++ are you running?

Yes, that's the exact probelm I was having.
|
|
|
|

What version of VC++ are you using?
Winmain@16 -- I think this is the expected entrypoint of a 16-bit windows program. It sounds like you are on a much older version of VC++ than the rest of us.
Anyhow -- make sure that your linker settings are for a console application, and there's no mention of windows.
How did you create your project file? Did you start a new one? OR did you cannibalize another one to get yours?

I'm using VC++ 6.0. I started a NEW project. Is there a way to download updates for VC++, I didn't see any update buttons in the program. Thanks again, I'm trying to get used to VC++.

updates? They should be available on the web. I've always had the benefit of the MSDN, so I am not sure where to find that. But I bet the downloads section on www.microsoft.com is a good place to start.
Let me get this straight. You create a new project, with the default settings, as a "win32 console application", and you get this problem? The new project dialog should come up and give you a multitude of choices.....

DWORD dw = 0;<br />
CRegKey rk;<br />
rk.Open(HKEY_CLASSES_ROOT,".txt");<br />
rk.QueryValue(dw,"(Default)");<br />
rk.SetValue("wordpad.exe","(Default)");<br />
rk.Close();<br />
The above code has no error but does nothing.
What should I change in my code to set the file extenxtion's associate.
In this example,use wordpad.exe when printing .txt files.
