Re: why setw and setprecision can't work correctly?

30-Jan-08 17:18

dear all

the following is my code, why setw and setprecison couldn't work correctly here...that means no space after setw(3)...the precision is not just 6....

#include <iomanip>
using std::setw;
using std::setprecision;

int n,i,j;
double a[number][row][column];

for ( n=0; n<number; n++)
{

for ( i=0;i<row;i++)>
{
for (j=0;j<column;j++)> {
a[n][i][j] = (double)rand()/RAND_MAX;

cout <<setw(3)<<setprecision(6)<< a[n][i][j]<< " ";
}
cout <<"\n";
}
}

thanks

cout << setprecision(7);
cout << fixed << a[n][i][j];

gentleguy30-Jan-08 13:50

30-Jan-08 13:50

dear all

how to create a dinamic array in c++? anyone has example code?

for example: a =10,b=3,c=4;

and then double aa[a][b][c]= (double)rand()/RAND_MAX;

thanks

#define number 10
#define row 3
#define column 4

void printarray (double arg[], const int number,const int row,const int column)
{
for (int n=0; n<number; n++)<br="" mode="hold"> for (int i=0;i<row;i++)>
for (int j=0;j<column;j++)> arg[number][row][column] = (double)rand()/RAND_MAX;

cout << arg[n][i][j] << " ";
cout << "\n";
}
int main ()
{
double firstarray[number][row][column];

printarray (firstarray,number,row,column);

return 0;
}

any problem for this code? but after debugged..problem...

Did you change name of variables?
double arg2[], const int number2,const int row2,const int column2)

Hello,
I am trying to build a Microsoft Text Service sample code from Microsoft site: "Simple Text Service Demo" . I have platform SDK for windows server 2003 and Visual Studio 2005 installed.
I have opened an empty Dll project in Visual Studio 2005 and built the project.
The problem is that when I try to register TextService.dll I get the message:"textservice.dll was loaded but DllRegisterServer entry point not found".
Does anybody have an idea what seems to be the problem?
Should I change the project settings?

Thank you very much,
T.R.

Did you add a .def file to your project that exports the DllRegisterServer function
(or did the sample code include a def file that you need to add to your project)?

CPropertysheet and tab ctrol

Hi,

I have a property sheet (in wizard mode) and on one property page of this sheet, I have a pop up dialog.

This pop up dialog has a tab control which is again showind a child dialog (no border, style = child).

So the picture looks like this

Property Sheet
Property Page launches
CMyDialog (pop up)
CMyDialog has CTabCtrl and Child dialog to show on the tab.

This child dialog doesn't receive any messages. If I click on the dialog, nothing happens. Tabs get changed though.
I am wondering if its a focus problem? how should i fix it.

The code to add this child dialog with the tab control looks like this

Init of Tab Control :

Tab Contrl->Add tabs;

Create a vector of dialogs

Instantiate the dialog class, add it to vector

Create and Repos the dialog window, and say ShowWindow.

Thanks in advance,
Misha

Can you show the actual code you use to do this?

Error in calling StackWalk64 [modified]

Hi all
I am using debuggin API for my purposes.
After I have initialized everything correctly each time I use StackWalk64 function it doesn't work.
Evenet if it returns TRUE I can see on the debug output

First-chance exception at 0x00000000 in TestMyStackTraceDebugger.exe: 0xC0000005: Access violation reading location 0x00000000.

I notice that the CONTEXT returned is almost all set to 0 and data returned in STACKFRAME sturcture are all 0.

What is wrong?
Each of the following (in order) was successful returning TRUE

-CreateProcess //with Debug permission
-WaitForDebugEvent
-OpenThread

CONTEXT ctx;
memset( &ctx, 0, sizeof( CONTEXT ) ); //init struct!
HANDLE threadHandle = OpenThread( THREAD_GET_CONTEXT , FALSE, de.dwThreadId );
GetThreadContext( threadHandle , &ctx );
-GetThreadContext
-SymSetOptions
-SymInitialize

STACKFRAME64 sf;
memset( &sf, 0, sizeof(STACKFRAME64));
sf.AddrPC.Offset = ctx.Eip;
sf.AddrPC.Mode = AddrModeFlat;
sf.AddrStack.Offset = ctx.Esp;
sf.AddrStack.Mode = AddrModeFlat;
sf.AddrFrame.Offset = ctx.Ebp;
sf.AddrFrame.Mode = AddrModeFlat;
#endif

StackWalk64(
IMAGE_FILE_MACHINE_I386,
gamerProcess,
threadHandle,
&sf,
&ctx,
NULL,
SymFunctionTableAccess64,
SymGetModuleBase64,
NULL );

Did you use your debugger to see where the code crashes exactly ? Check the state of the different variables to see if everything looks OK.

Why didn't you set the ContextFlags member of CONTEXT.
Is the thread in suspended mode, as recommended by documentation?

Probably the CHideAndSeek() class should help?

Seriously though, what is your requirement?
