Hi, I am trying to set the IPConnectionMetric parameter of a network adapter in Windows 7. The method that I need to use is the "SetIPConnectionMetric" in the Win32_NetworkAdapterConfiguration class. The problem is that the method returns an error code of 91 - Access Denied in Windows 7. However, this method works fine on Windows XP. Can someone give me pointers to a solution? I played around with the Local Security Policies, but couldn't find anything :| Here is more information about the method: http://msdn.microsoft.com/en-us/library/aa393303%28v=VS.85%29.aspx[^] Thanks, Karthik

True. I am compiling this in the Xilinx SDK.

Yes, I did check the image. It was garbled. Then I realized my mistake in the calculation of rows and cols... it should be 144 x 176. But that didnt solve the infinite loop until i was able to debug on hardware. I noticed j decreased to 0 and then increased back to the highest (32bit) value. Realized the mistake of making j unsigned int . Loop ends now :) Thank you!

@Luc: On the other side, my image file keeps growing > 1.8MB. The code never finishes.

I am trying to transmit about 75Kbytes of image data at 115200 baud. Ideally it should take about 5 secs. But this code seems to loop forever. Am I missing something obvious here?

#define rows 288
#define cols 352

for (j=rows-2; j>=0; j-=2)
{
for (i = (j*cols); i<((j*cols)+cols); i++)
{
cam_output = ram_read(i*4);
SendBuffer[0] = (cam_output >> 24) & 0xff;
SendBuffer[1] = (cam_output >> 16) & 0xff;
SendBuffer[2] = (cam_output >> 8) & 0xff;

        uart\_send(&SendBuffer, 3);    
        
    }        
}

void uart_send(u8 *DataBufferPtr, unsigned int NumBytes)
{
int i;

for (i=0; i<NumBytes; i++)
{
    XUartLite\_SendByte(XPAR\_UARTLITE\_0\_BASEADDR, \*(DataBufferPtr+i));
}

}

@gszakacs : That did it! I set SerialPort.DiscardNull = False and I was able to see all the hex values. I was using code from a previous project where I used 50-50 encoding to transmit data. Thank you!

Hi, I need to tranfer hex values through UART. But the problem is the default ASCII encoding of the SerialPort omits zeroes and such values (mostly below 0x14). What do I change this setting to in order to receive all values from 0-255 through the port? Please Help. For ex: 0x55, 0x55, 0x00, 0x00, 0x55, 0x55 comes through to the PC C# app as UUUU Regards, Karthik
