command line options in winmain with __argv

[eric dexter]

I want to compare what I get on the command line in winmain with an if statement.. I am getting a beginers error but I don't have an example to use to fix it.. cannot convert from 'const int' to 'char *' in this line if (__argv[1] = 'file'){};
I am very lost with this error and any help would be apreaceated

int WINAPI WinMain(HINSTANCE hInstance, //handle to current instance
                   HINSTANCE hPrevInstance, //pointer to the previous instance

void CCommandLineDlg ::OnBtnCmdLine( )
{
// TODO: Add your control notification handler code here
char CmdLine[80];
char CmdResult[80];

strcpy(CmdLine, GetCommandLine( ));
sprintf(CmdResu lt, "%s", CmdLine);
m_CommandLine.F ormat("%s", CmdResult);

UpdateData(FALS E);
}

I hope you understand that this is ASCII code and most Windows code is Unicode. You are not using the TCHAR mappings.

void CCommandLineDlg::OnBtnCmdLine() 
{
    // TODO: Add your control notification handler code here
    TCHAR CmdLine[80];
    TCHAR CmdResult[80];
 
    _tcsncpy(CmdLine, GetCommandLine());
    _stprintf(CmdResult, TEXT("%s"), CmdLine);
    m_CommandLine.Format(TEXT("%s"), CmdResult);
 
    UpdateData(FALSE);
}
 

Plus, strcpy, and sprintf are deprecated by Microsoft. You are supposed to use the newer safe _s versions.

Plus you have a hard-coded 80 that is a crash waiting to happen.

Those are good things to know certainly but I am using a compiler that was made by microsoft circa 2001 (and a borland c compiler from the same era).. It also doesn't realy answer the question as far as how to make that an array of strings from the command line. I am having a hard time finding an example on the internet.. The code I am trying to add a command line is here (if that is helpfull and it may not be)

You will have to post your code. I don't navigate to to other sites.

Remember, GetCommandLine fetches the entire command line as one string.
You will have to parse that string looking for the data that constitues your strings. Then you:
1) aallocate memory for the string as a char array
2) copy data from the command line to your allocation
3) add the address of the string to an array of char* that is you array of strings.
