helppp - Managed C++/CLI Discussion Boards

I figured it out, you need to use the Int32 class, AFAIK byte is a value type in MC++ so it couln't have the ToString associated with it.

So it's

<br />
Int32 test = 5432;<br />
String * testStr = test.ToString("X");<br />

What? Value types derive from System.ValueType which in turn derives from System.Object, so they do have ToString() defined.

C++/CLI will give C++ programmers first-class access to the CLI platform. Standardizing C++/CLI ensure that the code written by C++ programmers will be portable across the tools offered by multiple vendors.

Hi fellow developers,
I am new to C++.Net. I move my VC6 projects to C++.Net and one of the project behave a little bit strange. When I invoke the Add Member Variable Wizard for a control in a dialog box, the Control ID is blank and disabled. I suspect some setting has caused this to happened.
Does anybody have any information to fix this problem ?
Thanks for any information.

Hello,

I'm request some help. See subject. Smile | :)

OK guys well im sorta finished with my final project but i cant get it to work CORRECTLY. The program is to have a menu and ask the user to choose betweetn add, subtract, mult and divide. when they choose whatever one it will ask them a simple question. and if they get the correct answer or wrong answer it will ask them again if they want another problem. If they choose yes then it will give em another problem but if they choose no it will go back to the menu. I cant seem when they enter no it keeps say "enter another seed vaule" I want it to go back to the menu. Well here is the code. O and if they enter anything besides Y or N i need it to say sorry that is an incorrect choice. Here is the code:

#include <iostream>
#include <iomanip>
#include <cstdlib>
using namespace std;

int main()
{
int choice; float num1, num2, answer, correct;
char again;
unsigned seed;
do
{
cout << "\n\t\tSimple Math Tutor Menu\n\n";
cout << "1. Addition\n";
cout << "2. Subtraction\n";
cout << "3. Division\n";
cout << "4. Multiplication\n";
cout << "5. Quit The Program\n\n";
cout << "Please enter a choice: ";
cin >> choice;
if (choice <1 || choice >5)
{
cout << "Sorry that is an incorrect choice!"<<endl;
cout="" <<="" "please="" enter="" another="" choice="" "<<endl;
="" cin="">> choice;
}
cout<<"Enter a seed value: ";
cin>>seed;
srand(seed);
num1 = 1 + rand() % 10;
num2 = 1 + rand() % 10;

switch (choice)
{

case 1 : do
{

cout << "What is the sum of "<< num1 << " and " << num2 <<endl;
cin="">> answer;
correct = num1 + num2;
if ( answer == correct)
{
cout << "Congratulations you are correct!" <<endl;
}
="" else
="" {=""
="" cout="" <<="" "sorry="" that="" was="" incorrect"="" <<endl;
="" "the="" correct="" answer="" was:="" "="" "would="" you="" like="" to="" do="" another="" problem="" (y="" n)?="" ";
="" cin="">> again;
cout<<"\nEnter another seed value: ";
cin>>seed;
num1 = 1 + rand() % 10;
num2 = 1 + rand() % 10;
}while (again=='y' || again=='Y');
if (again != 'y' || again !='Y')
cout << "Sorry That is an incorrect choice" <

Just an FYI,
You might want to post in the forums for C++, this is Managed C++, which is code written to run on the .NET Framework.

Eventhough, you could comile with the /clr flag and run native C++ in the CLR, but the point is post in the right forum for better respones.

Here is the section out of my program that I am having problems with.

char first[20];

ifstream
fin;

openfile(fin);

char str[20];
char* trun;
char* trun2;
char *seps = "\0";

while (!fin.eof())
{fin.getline(str, 30, '\n');
fin.ignore(1);
cout<<str<<endl;
trun = strtok (str,seps);
cout<<"---"<<trun<<"---\n";
if (!doRetrieveVertex (graph, trun))
{doInsertVertex (graph, trun);}
strcpy(first, trun);

while (trun2 != NULL)
{ cout<<trun2;
trun2 = strtok (NULL, seps); \\Here

if (!doRetrieveVertex (graph, trun2))
doInsertVertex (graph, trun2);

cout<<"Internal while";
}
cout<<"External while";

}

If I comment out where it says "trun2 = strtok (NULL, seps);" Then it will run but it stays in an infinite loop inside that Internal while loop. But if I do not then I get a core dump. Please help me if you can it is due tomorrow. Thanks

1 2 50 3 70 4 23
2 1 50 3 34 4 75
3 1 70 2 34 4 80
4 1 23 2 75 3 80

Here is some sample data that we created and also I changed where seps is to " " so that it will break it into pieces. Basically what it is doing is getting the first line and then breaking off th efirst piece and retaining that and then breaking the others off and adding those. We are making a graph if you are wondering.

You can use your ifstream to read consecituve ints from your file directly without messing with this C ugliness.

And you asked in the wrong forum, this has nothing to do with MC++

You are accessing uninitialised memory for turn2 at

I am not sure about the correct answer,
however this book is all about MFC <-> .NET

i wanna ask how to link a dictionary wid my program if i want to code a dictionary in c++ and link it wid thesaurus as we can consult a word in MS word.

Hello,

I just found this article :
http://www.codeproject.com/csharp/rotateimage.asp

but the code is in C#...

is it possible to use it in a Managed C++ project ?
and what do i have to do ?

thanks

Of course you can, they are both .NET langauges.

If the C# contents are in project form you want to just add the C# project to your MC++ solution.

If the C# contents you want are in .dll form, then you just add a reference to the C# .dll, from your MC++ solution.

If you don't know how to add projects/references view the SDK/VS.NET relevant documentation.

p.s. if the c# logic you want is embedded in an aspx, then just create a c# library and cutnpaste from aspx to your library.

thanks for all
it's working fine now Smile | :)

Does any one know how to map a network drive using manage c++?

all,

i was asking if i can develop an ASP.NET Pages with
MC++ or even the new C++/CLI

i know that someone post an article about this before, but as i can remember , someone reply and he wasn't recommending that approache,

thanks

Please see this article
http://www.codeproject.com/managedcpp/helloworldmc.asp[^]

at the bottom (discussion) look for Nick Hodapp's post, this has a summary of implications and link to ms kb article.

It has nothing to do with .cpp,.h files.

Does anyone know where I can find low level I/O tutorials such as writting to the boot sector, or directly to the disk. I'm sure i need to do this using assembly, but any tutorial in the right direction would be a nice start. How about a tutorial to get system information, ie. drives, cpu, ram, etc, preferable not through windows, again, probably through assembly.

thanks

This is the wrong board for that question. This is about MC++, that runs under CLR.

Try posting in an assembler programming forum.

I have visual c++ .net 2003 and am trying to add an MSchart to a form. I've selected it from the coms list and added it to the tool box. I then go to ad it to the form and get an AxImp.exe error message telling me it can't find AxInterop.OWC10.dll even though it's in the debug directory of the project. I have the same problem if I try using any other AxtiveX component, just a different dll in the error message.
