Variables do not get passed to each other.

You can, in some cases, convert from one type to another.

CString myStr = _T("hello");
TCHAR *myVar = (LPTSTR) (LPCTSTR) myStr;

you meant using _tcscpy(), strcpy() or strncpy(), not using operator=(), didn't you ?

non, the original poster just wanted to cast a CString to something alse, not make a copy ...

or at least that's what it looked to me.

Dump file reading via WinDbg

Axter6-Dec-05 4:28

I'm trying to read a Dump file from a client, and I'm not sure how to do this with WinDbg.

1. If I'm not certain about the client's OS, can I download multiple Windows OS symbols to the same path, or do I need to download the symbols to seperate path for each OS version?
2. If I have the symbols for an OS with service packs installed, can I still use these symbols with a dump file from an OS that doesn't have any service packs installed?
3. Is there any clean way to examine the dump file to determine which OS it's for, and what version or service pack it has with it?
4. If I wanted to use VC++ 7.1 to examine the dump file, exactly how would I do that?

I'm currently waiting for the client to send some msinfo32 output that I believe will tell me about the OS and service pack, but I was wondering if there are other options for getting this information via the dump file.

Have you looked into the WM_CTLCOLOR message, or the OnCtlColor() handler?

hi,
I have created a dialog using Cproperty sheet but facing difficulty while setting the focus on Help button from Cancel button and vise-versa using arrow keys, though using tab it works properly. Also, its not using Active Control X.

Need to get Command line argument and add to this simple function

Hi there!

I'm quite new with C++, using other languages but now i needed to write an Printer USB routine in C++, and i need some help!

It's like this

BytesToWrite = sprintf( (char *) szBuffer, "\033F\r\033B 512 600 4 1 2 3 150 1 999999999\r\033I\r");

WriteFile( hDevice, szBuffer, BytesToWrite, &cbWritten, Null);

etc, etc, etc

I need to replace the 999999999 with the first command line argument (paramstr(1) Can someone help me with this!?

What this function does, is to send ESC commando codes to an Zebra Eltron printer.. Print barcode.. 999999999 is the barcode, but i need be able to call this little application from another application then with the barcode as command line argument.!

Best regards

Does your program have a main() function?

Hi, yes!

Srry, didn't mention.. but here it comes!

int main(int argc, char* argv[])
{
TCHAR DeviceName[1024];
HANDLE hDevice = NULL;
DWORD cbWritten;
DWORD cbRead;
BYTE szBuffer[1024];
DWORD BytesToWrite;
StringType SlumpNum;

// This function enumerates the printer class devices and detects the appropriate
// device

CCmdLine cmdLine;

EnumeratePrinter(( LPGUID) &GUID_CLASS_ZEBRA_USB,
DeviceName,
PRINTERNAME);
hDevice = CreateFile(DeviceName,
GENERIC_READ | GENERIC_WRITE,
0,
NULL,
OPEN_EXISTING,
0,
NULL);
// Read Ribbon

BytesToWrite = sprintf( (char *)szBuffer,
"\033!RIBBON\r");
WriteFile( hDevice,
szBuffer,
BytesToWrite,
&cbWritten,
NULL);

// To read you need to send "\033E 2\r"

BytesToWrite = sprintf( (char *)szBuffer,
"\033E 2\r");
WriteFile( hDevice,
szBuffer,
BytesToWrite,
&cbWritten,
NULL);

ReadFile( hDevice,
szBuffer,
1024,
&cbRead,
NULL );
// End of ribbon read

// Start Encode Data
// Fill in the data in firmware buffer
// First track ZEBRA1 command: \033&B 1 ZEBRA1\r
// Second track Age command: \033&B 2 28\r
// Third track YOB command: \033&B 3 1975\r
// Encode all three track
// command: \033E*\r

BytesToWrite = sprintf( (char *)szBuffer,
"\033F\r\033B 512 600 4 1 2 3 150 1 999999999999\r\033I\r");
WriteFile( hDevice,
szBuffer,
BytesToWrite,
&cbWritten,
NULL);

And you can see the 999999999999 that i would like to insert the first command line parameter instead...

Andreas

Okey, so one step further Smile | :)

.. guess i used the argv correct
same as ParamStr in Delphi and so on.

Ok, now i'm having trouble to inserting that string into the function.

Like this, wich doesn't work:

Argument = argv[1];

BytesToWrite = sprintf( (char *)szBuffer,
"\033F\r\033B 512 600 4 1 2 3 150 1 "&Argument&"\r\033I\r");

Try:

sprintf(szBuffer, "\033F\r\033B 512 600 4 1 2 3 150 1 %s\r\033I\r", argv[1]);

Overloading << operator?

Cristoff

6-Dec-05 2:03

I've tried to overload the << oprator, so that I can output to a file and to a console at the same time but I have no success. I cannot find a solution in Internet and I get the error message: ambigous overload of operator <<...

Any ideas what to do?

I want to be able to use this operator to output something like:
logfile << "data";
but still to be able to do this:
cout << "out";

Thank you!
