From my experience, 99% of the time this error is received, it is after the post has been made, but before the results are sent back to the client's browser.

You could try resetting the focus back to your window in its onfocus() event, but I'm not entirely sure it will work.

Besides, a window that always has the focus will irritate an awful lot of users. The purpose of Windows is to allow users to switch to other tasks. To deliberately break this model will frustrate and anger many users...

Can you be a bit more specific? Your question could be answered in a dozen different ways.

I would like to store the data from the sensor after intializing or sending all the commands to the sensor i,e for continous data output??

David Crow28-Feb-06 5:54

Does this "sensor" have an API? How is it connected to the computer?

Via Serial port(rs232)

So just search CP articles for "serial."

You can also Google for the same.

How to record/process data sent from the sensor????

David Crow28-Feb-06 7:56

Having not coded very much serial stuff before, this is just a guess. Those other articles I referenced would have shown this, but I think you'll use something like:

HANDLE hPort = CreateFile("\\\\.\\COM1", ..., OPEN_EXISTING, ...);
ReadFile(hPort, ...);

Also see here.

am using Send() and Recieve() functions

lnewlength = send(lnewSocket,(char*)lnewData,lDataLenght,0);
lnewlength= recv(lnewSocket,(char*)lData,1024,0);

David Crow28-Feb-06 8:09

Can those be used with serial communications, or are they for sockets only?

Then why are you using them with a serial port?

Actually, if i would like to store the data of the "lData" parameter when lnewData[]={.....}(soem bytes) in storearray[], the how could i do? Is this correct??

if(lnewdata[8]==({..,..,..,..,..})

{
BYTE storearray[1024]= lData;
}
can i work so with a string???

What is lnewdata? Are you comparing or (supposed to be) assigning?

What is lData?

What is this? Try:

BYTE compare[8] = {0x02, 0x00, 0x02, 0x00, 0x20, 0x24, 0x34,0x08};
if (memcmp(lnewData, compare, 8 * sizeof(BYTE)) == 0)
{
    memcpy(storearray, lnewData, 8 * sizeof(BYTE));
}

Hello!

When I compile the release version of my application, it depends on MSVCP80.DLL and MSVCR80.DLL. Unfortunately this prevents the application from being run on a computer, where these runtimes aren't installed.

How can I remove these dependencies? Any way to statically link to MSVCP80.DLL and MSVCR80.DLL?

I assume there is some linker switch that does this and I've overlooked it?

Many thanks in advance and best regards
Dominik
