I've got a problem.
I Want that when you press the button (see link plz) open a pdf file with the instructions of use.
http://www.imagecash.net/image.php?file=265709030
I can open file use this code
<br />
ShellExecute(this->m_hWnd,"open",<br />
"C:\\motor.pdf","","",SW_SHOW );
But this program is to use for many people, and the path changes computer to computer.
How can I solve this?
How can I make a setup that includes MFC files with microsoft visual studio 6?
thx

You can open the file Open dialog
Ask the user to select the file to open
Get the path from that fileopen dialog.
and then use ShellExecute with that path
Somethings seem HARD to do, until we know how to do them.

That seems logical no ? It won't start a search on your computer to find the required file. Supply the file with the program and put it in a specific folder where it can be found, that's the standard solution.

Does that have something to do with your previous question  ? If yes, I don't understand.

either keep that path in any inifile or ask user about file path when ever you Application run!

When u want to remove the close menu.
write
ModifyStyle( WS_SYSMENU,0 );

When you want the Sysmenu to be visible
SetWindowLong(GetSafeHwnd(),GWL_STYLE,WS_SYSMENU | GetWindowLong(GetSafeHwnd(),GWL_STYLE));
RedrawWindow(NULL, NULL,RDW_ERASE | RDW_INVALIDATE | RDW_FRAME | RDW_ALLCHILDREN); When you don't want the Sysmenu to be visible
SetWindowLong(GetSafeHwnd(),GWL_STYLE,~WS_SYSMENU & GetWindowLong(GetSafeHwnd(),GWL_STYLE));
RedrawWindow(NULL, NULL,RDW_ERASE | RDW_INVALIDATE | RDW_FRAME | RDW_ALLCHILDREN); Hope this helps you

i am trying to read the path of installation of adobe acrobat from the registry( is there any other way), in order to launch it in my program. i have tried RegQueryInfoKey to get the value from
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppPaths\AcroRd32.exe
from the default string in this key. were the path is.
but i am unable to read the value.
please help

Hi,
In which way do you want to read out any value using RegQueryInfoKey ?
To read value use RegQueryValueEx.

thanks for pointin out... but i have used RegQueryValueEx as well. but i am not sure if i am doin it correctly.
but nothin worked.

HKEY hKey = NULL;
LONG lRet = NULL;
char szProductType[1024] = { '\0' };
DWORD dwBufLen=1024;
lRet = RegOpenKeyEx( HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\AcroRd32.exe", 0, KEY_QUERY_VALUE, &hKey );
if( lRet != ERROR_SUCCESS ) return FALSE;
lRet = RegQueryValueEx( hKey, "", NULL, NULL, (LPBYTE) szProductType, &dwBufLen);
RegCloseKey( hKey );
It has to work properly - if not check which error codes returns RegOpenKeyEx & then RegQueryValueEx.

i tried that too. the return valur in both the function is 2 and the data in szProductType is 00000s. i am usin RegQueryInfoKey funtion before the code sent by u. is that an error?
|
|
|
|
|
check that registry path looks like:
"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\AcroRd32.exe"
and NOT
"SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\AcroRd32.exe"
- this is very popular mistake

this is how i am usin it:
lRet = RegOpenKeyEx( HKEY_LOCAL_MACHINE, (LPCWSTR)("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\AcroRd32.exe"), 0, KEY_QUERY_VALUE, &hKey );
lRet = RegQueryValueEx( hKey, (LPCWSTR)"", NULL, NULL, (LPBYTE) szProductType, &dwBufLen);
as the complier was givin error for the 2nd parameter in both the functions in had to include (LPCWSTR) as a type castin measure
there was an pointer in the szProductType but in it was an array of zeros.

if you using UNICODE version of functions you should give wide text path:
lRet = RegOpenKeyEx( HKEY_LOCAL_MACHINE, (LPCWSTR)(L"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\AcroRd32.exe"), 0, KEY_QUERY_VALUE, &hKey );
the same thing will be in case RegQueryValueEx. In wide version
lRet = RegQueryValueExW( hKey, L"", NULL, NULL, (LPBYTE) szProductType, &dwBufLen);
... and all ... good luck!

Why not just use AssocQueryString(..., ".pdf", "open", szPath, ...)?

it is a key at the location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppPaths\AcroRd32.exe
AcroRd32.exe is a folder and contains two vlaues default and Path.

Try CRegKey
CRegKey myKey;
myKey.Open(HKEY_LOCAL_MACHINE,"\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\AppPaths\\AcroRd32.exe")==ERROR_SUCCESS)
{
CRegKey::QueryValue function!
}

I am looking for the header file (can be parallel.h ?) containing the definitions of the constants IOCTL_XXXXXX allowing to control the parallel port using the method DeviceIoControl() in Visual C++ under Windows XP.

The file you're looking for is indeed parallel.h and it ships with the DDK (Driver Development Kit).
