Hi, im writting a small W32 application (non MFC) and i need to parse the command line for passed arguments, and since the app MUST be compiled for unicode, the MSDN docs say i should use the GetCommandLine() function to get a unicode version of it, and it also suggests using CommandLineToArgvW() to get a main() style array of arguments and a count.
inside my winmain(), heres what i do:
<br />
int argcount=0;<br />
LPWSTR* arguments=CommandLineToArgvW(GetCommandLine(), &argcount);<br />
<br />
.<br />
.<br />
.<br />
<br />
if(arguments)<br />
GlobalFree((HGLOBAL)arguments);
the problem is that in the GlobalFree() line, the app takes an exception and crashes. but MSDN sais i should do the GlobalFree!
i quote:
"It is the caller's responsibility to free the memory used by the argument list when it is no longer needed. To free the memory, use a single call to the GlobalFree function."
any idea of what im doing wrong?
thanks!

hi, thanks for your reply.
when i ran that code in debug mode on my XP machine, it just caused a "first chance exception" shown in the output window of vc, (i dint even noticed it the first time) later i compiled the release version and it worked OK on windows XP, but when i tried it on NT4 server, then the exception became a "memory cant be read" error message, and the program crashed.
heres the code in "do stuff":
// checkout the command line for passed arguments
int nargs=0;
LPWSTR* cmdargs=CommandLineToArgvW(GetCommandLine(), &nargs);
LPWSTR argument=NULL;
for(int i=1; i<nargs; i++)
{
argument=cmdargs[i];
switch(i)
{
case 1: // 1st arg is times to do the test
{
int tests=_wtoi(argument);
tests=tests>=0? tests : 0;
if(!tests)
{
if(wcscmp(argument, L"0")!=0) // atoi failed or really zero?
days=DEFAULT_TEST_TIMES; // invalid argument!
}
mttimes=tests;
break;
}
case 2: // 2nd is "F" or "f" for File, (writte a log file)
if(wcsicmp(argument, L"F")==0)
dolog=TRUE;
break;
default:
break;
}
}
// release the memory
if(cmdargs)
GlobalFree((HGLOBAL)cmdargs);
the first chance exception occurs in the GlobalFree() line, if i remove it, then it runs fine on both XP and NT4 and both release and debug versions.

Greetings!
I'm a computer science major. I'm required to use Microsoft C++.net. I'm using the standard edition version 2003. This is the fisrt time I've used this software.
I need to turn in the .cpp, .dsp, and .dsw files. The only problem is that I can't find them. I used the search frature from the start menu and it reports the files that were created along with the software isntillation. I created files and I can't find the .cpp, .dsp, or the .dsw files that go with the files I created. I'm using Windows 2000.
Will you help me find thoes files?
Thanks,
Leonard Fear

.dsp and .dsw are the VC 6 project files. The names and formats changed in version 7. If you absolutely have to have dsp/dsw, there's a 7-to-6 project converter here on CP.

What doesn't work?

i am not using MFC.
i am trying to send an application the key strokes Shift-F5.
what i did was this (i used the decimal values for the key codes):
SendMessage(hwnd,WM_KEYDOWN,116,0);
SendMessage(hwnd,WM_KEYDOWN,16,0);
SendMessage(hwnd,WM_KEYDOWN,16,0);
SendMessage(hwnd,WM_KEYDOWN,116,0);
This combination only performs the F5 key press and completely ignores the fact that i used WM_KEYDOWN with shift before that.
i tried using Spy and found that i am sending the correct messages (like i said - F5 does work). Spy showed that WM_KEYDOWN is the message being sent when i press the keys in that order myself.
i tried other combinations this way with other windows and found out that it is completely NOT working - even with alt and control keys.
how can i make it work? can anyone see the problem?

i think lParam indicates the repeat count, so shouldnt it be atleast 1 instead of 0?
|
|
|
|
|
when i tried it with lParam = 0, it DID work for F5. i could see that F5 keydown was working, but not the combination Shift-F5.
anyway - i also tried with lParam = 1, and got the same result.
any ideas?

Hiya I have a .ini which I am reading through looking for [PROFILE2]
and then reading the database name out of the field "Database". It works fine up to the point of displaying the Database Name.
I copy the Database Name into a variable called "Database Name". When I do this, I display Database Name, but if I try to display it OUTSIDE THE LOOP, it is already over-written by the last line of the file.
Here is my code:
ifstream infile;
char szLine[256] = {0};
char Profile[11] = "[PROFILE2]";
char Database[10] = "DATABASE";
char* DatabaseName = new char[20];
infile.open( "\\security.ini",ios::out );
if( !infile )
cerr << "Unable to open file.";
infile.seekg( 0,ios::beg );
while( infile.getline( szLine,256,'\n' ) )
{
sprintf( szLine,"%-s",szLine );
if( strncmp( szLine,Profile,strlen( Profile ) ) == 0 )
{
while( infile.getline( szLine,256,'\n' ) )
{
if( strncmp( szLine,Database,strlen( Database ) ) == 0 )
{
DatabaseName = &szLine[strlen(Database)+1];
AfxMessageBox( DatabaseName ); // displays here
}
}
}
}
AfxMessageBox( DatabaseName ); // error displays a garbage value here!!
infile.close();
I have tried using break when the database name is found but no luck. Can anyone help me with this??

You should break out of the loop, otherwise you will keep reading until you get to the end of the file.
while( infile.getline( szLine,256,'\n' ) )
{
if( strncmp( szLine,Database,strlen( Database ) ) == 0 )
{
DatabaseName = &szLine[strlen(Database)+1];
AfxMessageBox( DatabaseName );
<code>break;</code>
}
}
You could write this using much less code by calling GetPrivateProfileString[^]

I've been having problems with this for quite a while. I found the problem now... there is an terminator character that is in the encrypted text.
I the MSDN code encrypted the file... wrote it to another which they are both the same length but when i try to read teh encrypted file to a string it stops at that position.... how can I get the whole file set to the string or show all of it in a CString?

are u encrypting something and getting zero's in the middle of the data? is that what ur saying?

Well, it encrypts a long CString of XML, it doesn't have any special characters. It is encryted with the CryptoAPI. Writes it to a file.
(after a lot of trouble I decided to go this route, because the code on CryptoAPI does this and I couldn't get it to work with the string).
Anyways when I use CFile to read the file thats encrypted, it sees teh right length of the file but when I use Read to a char it stops at liek 236, but the read function returns the file length.

what cipher function are u using?
sometimes the encrypted data can result in zero's in the data stream so u can change the cipher or (prolly better) read the file in binary mode

another thing u can do (which is what i do) is hex encode the data after encryption ... then u know u have a valid ascii data stream

Anybody have a suggestion on how I could continue to use MFC/C++ with XML and avoid COM?  I'm looking for a way to exchange XML in a robust, straight-forward fashion between my (server) process and another (server) process.

Thanks for trying. Unfortunately, using the CString-class breaks down quickly when a CDATA section is placed in the XML document.

I've been using XML4C quite happily with MFC for a couple years. It handles pretty much everything there is to handle in XML land. Google "XML4C" for more info. You'll find it @ IBM's site.
