To Miteh,
How do you attach a code in codeproject?
In the doctemplate, the view has a pointer to the document through the function GetDocument().
In my created view the function GetDocument() was also included. There was no complain with the ASSERT command. Why is it so?
How was the pointer created between the application view and document?
Thanks.

Hello,
First of all sorry for late reply,
Regarding GetDocument() function, just check the variable type (is it CDocument or CXDocument [where X = project name])
Regarding attaching the code, I doubt that you can attach your code files here. But what you can paste the code snippets. That is best way to share your problem.
And further if you want to send any code files then you can directly mail me at mitesh.patel@patni.com
ASSERT will not give any error because, calling GetDocument() method is absolutely valid.
So send the following code sinppets:
1. CApp:InitIntance()
2. CYourView:OnDraw()
Cheers
Mitesh

To Mitesh,
Thanks for your reply.
Had managed to get the answers to my problem after many hours of trail and errors and readings.
Besides the normal, any tips or links on becoming an expert on MFC?

"The Jet VBA file (VBAJET.dll for 16-bit versions, or VBAJET32.dll for 32-bit versions) failed to initialize when called. Try reinstalling the application that returned the error."
Any ideas how to fix this?

Does anybody have a simple "Roll the Dice" program?
I just need to get my hands on some working code to study.
I have been trying to build this program on my own but I get tripped up when trying to implement other functions besides main. I am a beginer, what can I say
-Thanks
Mark

There's nothing wrong with that. We were (and still are in many ways) all beginners at one point.
While I don't have a working program, I can give you a hint to get you going: use the rand() function to obtain a random number. Restrict the random number to the interval [1..6] by using the % operator.

Still working on my program.
And here is what I got so far:
#include <stdio.h>
#include <stdlib.h>
void showone();
void showtwo();
void showthree();
void showfour();
void showfive();
void showsix();
char getans();
void printlines(int n);
main()
{
int r;
char ans;
ans = getans();
while(ans== 'y')
{
r = rand()%6 + 1;
printlines(2);
if (r==1) showone();
if (r==2) showtwo();
if (r==3) showthree();
if (r==4) showfour();
if (r==5) showfive();
if (r==6) showsix();
printlines(2);
}
printlines(2);
}
char getans()
{
int ans;
printf("Throw y/n ?");
ans = -1;
while (ans == -1)
{
ans=getchar();
}
return ans;
}
void printlines(int n)
{
int i;
for(i=1 ; i<=n ; i++) printf("\n");
}
void showone()
{
printf("\n * \n");
}
void showtwo()
{
printf(" * \n\n");
printf(" * \n");
}
void showthree()
{
printf(" * \n");
printf(" * \n");
printf(" *\n");
}
void showfour()
{
printf(" * * \n\n");
printf(" * * \n");
}
void showfive()
{
printf(" * * \n");
printf(" * \n");
printf(" * * \n");
}
void showsix()
{
int i;
for(i=1 ; i>=3 ; i++) printf(" * * \n");
}
The problem I am having is I can't figure how to make it loop back to the y/n. How it is now it goes on forever. How can I make it ask "Throw y/n" each time?
Thanks

Try changing
ans = getans();<br />
<br />
while(ans== 'y')<br />
{<br />
...<br />
}
to
while(getans()=='y')<br />
{<br />
...<br />
}
That should make it ask the question each time.

Hi,
Try doing this:
void showone();
void showtwo();
void showthree();
void showfour();
void showfive();
void showsix();
char getans();
void printlines(int n);
void main()
{
int r;
char ans;
srand( (unsigned)time( NULL ) );
ans = getans();
while(ans== 'y')
{
r = rand()%6 + 1;
printlines(2);
if (r==1) showone();
if (r==2) showtwo();
if (r==3) showthree();
if (r==4) showfour();
if (r==5) showfive();
if (r==6) showsix();
printlines(2);
ans = getans();
}
printlines(2);
}
char getans()
{
int ans;
fflush(stdin );
printf("Throw y/n ?");
ans = -1;
while (ans == -1)
{
ans=getchar();
}
return ans;
}
void printlines(int n)
{
int i;
for(i=1 ; i<=n ; i++) printf("\n");
}
void showone()
{
printf("\n * \n");
}
void showtwo()
{
printf(" * \n\n");
printf(" * \n");
}
void showthree()
{
printf(" * \n");
printf(" * \n");
printf(" *\n");
}
void showfour()
{
printf(" * * \n\n");
printf(" * * \n");
}
void showfive()
{
printf(" * * \n");
printf(" * \n");
printf(" * * \n");
}
void showsix()
{
int i;
for(i=1 ; i<=3 ; i++) printf(" * * \n");
}

What does the fflush() function do?
Thanks

The fflush() function flushes the console input before u use getchar().

Basicly what the other two guys said, except you might want a do/while loop and not a standard while loop. Look it up, the do while will always give you one roll before asking if you want to roll again.
I recomend "the art of computer programing" by Donald Knuth http://www-cs-faculty.stanford.edu/~knuth/taocp.html which describes random numbers in far more detail than you ever thought possible. These are unfortuntly advanced books, completing one should be considered equivelant to a PHD! Still you should be aware of them, and (if you can afford them) have them on the bookshelf.
What I want you to get from these books: random numbers have been the most popular subject in advanced computer science since before there was comptuer science. I estimate that 1/3rd of all PHDs in computer science studied random numbers (and there is still pleny of room for more study) Your simple program is not complete until you understand something about random numbers.
In particular, the most common implimentation of rand() will ALWAYS give a odd-even-odd-even sequence! This is not something you want I'm going to guess. Issues like this are what seperate simple programs like yours (that look just fine) from complex programs done by an expert. You can never know it all, but I've just given you an area to look.

I'm having trouble giving command line arguments to VS.NET 2003 in debug mode without opening a prompt.
My debugging properties are as follows.
Command: cmd.exe
Command Arguments: -input test.scn -output test.tga.
(basically input scene description file and output image file)
When I start the debugger, argc is always 1, which means only the executable name was found in the command line. So my arguments are never read. I tried setting input to "test.scn", and output to "test.tga" in main(), same result (input and output are c++ strings in the main function). I also tried setting the working directory to .\Debug. without success. The test.scn file is in my project's Debug folder.
What am I missing?
Cheers, blackmesa.

Not sure about VS.NET 2003, but under VS6 you can specify command-line parameters under the Project Settings...

Well I'm specifying the arguments from the Project Properties, which is pretty much the equivalent of Project Settings under VC 6.

Hello,
I am try to create a virtual desktop on windows 98SE and 2000.
Basically what I'm trying to do is to set the desktop to be twice as wide as the screen resolution. e.g. 2048x768 for the desktop and 1024x768 for the minitor resolution. Windows should then allow you to simple scroll the monitor (view port) left/right over the desktop... Easy..
So what I have tried is the SystemParametersInfo() call with the SPI_SETWORKAREA flag. However this call returns NULL, so I called GetlastError() and this returns 87 (INVALIDE_PARAMETER) This I think is due to the security mask ?? any ideas please..
Or better still have anyone written this and has some source.

Looks like you may have put your #include "resource.h" line (or the line that #includes your dialog's .h file) between the #ifdef DEBUG .. #endif block. It needs to be outside.
