Might be.
In that case, there is no single answer. Every accessible member of the base class is "added", so the functions added really depend on the base class. The only thing you can say is that "everything is an Object", so the accessible Object-functions are available for "everything".
Cheers,
Sebastian

I have real time data to be displayed on a X-Y graph. I need to use Double buffering to avoid flickering.
How to accomplish Double Buffering in Managed C++.
|
|
|
|
|
There are several approaches. If you use GDI+ to draw, one simplest is creating a bitmap graphic object as the buffer. Draw to the buffer. Whenever necessary, draw (copy) the buffer to the screen.

I know this sounds like an ad, but have a look at ZedGraph. Its GPL'ed, documented both on CP and SF, and available from SF or CP as well.
You would be able to offer zooming, human-readable axis-dimensions (min, max, stepsize) and other useful stuff.
Cheers,
Sebastian

I hope this will help
// in order to solve flickering i have to use double buffering
this->SetStyle( ControlStyles::AllPaintingInWmPaint, true);
this->SetStyle( ControlStyles::UserPaint, true);
this->SetStyle( ControlStyles::DoubleBuffer, true );

I have an upcoming TAPI project to be written using Visual C++ 2005. Im just wondering is there some new fan-dangled API in the dot net framework that supercedes the TAPI API?

I want to know if declaring soemthing like this makes sense?
I have a class whose declario is as follows:
namespace Utility {
class Filebase : public fstream {
public:
and I want to declare a vector of objects of this class. Currently w/o vector I am using an object of this class as:
string signal = ".s_"+layer+"_" + toString (iStage);
Utility::Filebase temp (signal, ios::out);
temp.create(signal);
I want to use Filebase temp using a vector
Is this possible in C++?
Thanks

I am looking for a way to add a 16 X 48 matrix of owner drawn buttons to a small
utility I am developing in VC++ 2005. Can anyone direct me to specific articles
or code to accomplish this task. I want to preserve 2d addressing. Initialization
might go like:
private: System::Windows::Forms::Button^ Mybutton[][];

Go through this code, it may help
array<Button^,2>^ myButton = gcnew array<Button^>(10)(10);
myButton[0][0]=gcnew Button();
myButton[0][0]->Location = System::Drawing::Point(300, 189);
myButton[0][0]->Name = L"button123";
myButton[0][0]->Size = System::Drawing::Size(148, 41);
myButton[0][0]->TabIndex = 1;
myButton[0][0]->Text = L"Added";
myButton[0][0]->UseVisualStyleBackColor = true;
this->Controls->Add(myButton[0]);
this->myButton[0][0] ->Click += gcnew System::EventHandler(this, Form1::button123_Click);

int * funcArg(int *a ) {
int DLLArg [] = {100,200,300};
a=DLLArg;
return a;
};
I have exported this function in the dll (i have checked it with dumpbin.exe)
But I can not handle this function in c# client. My code in c# is as: ( ıt gives this error. "An unhandled exception of type 'System.Runtime.InteropServices.SafeArrayRankMismatchException' occurred in CSharpClient.exe
Additional information: Safe array of rank 51241 has been passed to a method expecting an array of rank 1."
What should I do? URGENT help!!!
namespace CSharpClient
{
class Class1
{
[DllImport("DenemeNonMfcDll.dll",EntryPoint="?Sub@DLLclass@@QAEHHH@Z")]
public extern static int Sub(int a, int b);
[DllImport("DenemeNonMfcDll.dll")]
[return: MarshalAs(UnmanagedType.SafeArray)]
public extern static int [] funcArg(int [] a);
public static int [] intArray = new int [3] {0,1,2} ;
static void Main(string[] args)
{
foreach (int num in funcArg(intArray) )
{
System.Console.WriteLine(num.ToString());

Console.WriteLine("Press any key to continue...");
Console.ReadLine();

Hi,
I want to use a GUI component, which was developed using the MFC, in a .Net program. Is it possible to access the classes using some mc++ wrapper layer? Are there any problems due to the use of the MFC due to which I can not access this component with .Net? If this is possible, how do i do this? Do you know any sample, where somebody did something similar?
Cheers

hi all,
I am working in VC++6.0 IDE.
I want to create a pop-window which displays some message.
Can anyone assist me on how to proceed further and where i can get some useful information.
Thanks in advance,
Veenu.

Use message box.

hi jun,
Thank you for the reply.
I tried out Message Box function and it is working fine for me.
I have a doubt.
I want to send a variable value to the mesaage box to output it in the popup .
I mean if i have smthing like this:
for (i=0;i<2;i++)
{
MessageBox( .... );
}
Is there anyway to include this variable , "i" value into the mesage box ?
Thanks in advance,
Veena.

|

Yes. Although Message Box only takes string prarameters, you can always put variables into the string you're going to display. For example,
char str[256];
for (i=0;i<2;i++)
{
sprintf(str, "The variable is: %d", i);
MessageBox(str, ...);
}
Note this is just native C code.
Best,
Jun

CString str;
for(i=0;i<2;i++)
{
str.Format("%d",i);
MessageBox(str);
}

Hi All,
I've just switched my project from old VS6 to VS.NET 2005.
At compile time, I receive a lots of warning about 'deprecated' functions . Some of them have been disabled using _CRT_SECURE_NO_DEPRECATE. Others are still there.
I would like to use #pragma warning(disable : 4996) without using _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES to override functions with their secure version.
Files are too much to write in each of them: do you know if it is possible to set some projecet settings, or a place where to inserte a single #pragma so that it is valid for all files?
Regards
Manu
