I think the easiest way is to use InnoSetup[^]. This is an installer with which you are able to register ActiveX controls during the installation.

Hi,
You may be having the MFC DLLs to support the EXE file.
This is because of the Operating system you are using.
The price of anything is the amount of life you exchange for it.
Thanks and Regards.

Thank you.
I am just looking for the DLLs.Do you have the more useful method?
|
|
|
|
|
Use Dependency Walker & scan the executable.This will find out in case if you are missing any needed DLLs.

I Need to access a File, where only One instance of an App has Read/Write Access, and where all other instances have read access only.
I First try to Open as Follows:-
m_hFile=CreateFile(FileName,GENERIC_READ|GENERIC_WRITE,
FILE_SHARE_READ,NULL,OPEN_EXISTING,
FILE_FLAG_WRITE_THROUGH,NULL);
and designate some Internal State as MASTER.(i.e.: It can Change the File)
if I get a Share Violation, I try:-
m_hFile=CreateFile(FileName,GENERIC_READ,
FILE_SHARE_READ,NULL,OPEN_EXISTING,
FILE_FLAG_RANDOM_ACCESS,NULL);
and Designate some Internal State as SLAVE. (it can only Monitor the File)
GetLastError reports a Share Violation when I try to open a second Instance, even though I only try to open it for reading.
What am I doing wrong.
Regards, 
Bram van Kampen

According to the table here[^], if you first open the file
using
GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ
then subsequent opens need to use
GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE.

Hello,
to identify local machines I need to read the Computer SID.
(like psgetsid.exe does)
Does anybody have a bit of source for this?
OS: Windows 2000 and up.
Compiler: VC9 using MFC (not C#). But I'll take anything you have even VB or Delphy
Mention: Computer SID, not a logon, user SID. Any computer have one. It don't need to be in a domain.
I searched hours in google and forums.
Thanks in advance
Stefan

From what I can find, the last 96 bits of
HKEY_LOCAL_MACHINE\SECURITY\SAM\Domains\Account\V
is the machine SID.

Hello,
on my computer Vista, no domain, the hive \\hklm\security is complete empty 
\\hklm\sam\sam is empty too
Stefan

You have to enable viewing - by default (even if you're
an administrator), you don't have read rights in the security
key. You can give yourself permissions in regedit however.
Anyway, I played around with this, and the following code
gives me the same SID found in that registry hive (on Vista):
DWORD SIDLength = 0;
DWORD RefDomainNameLength = 0;
SID_NAME_USE SIDNameUse;
::LookupAccountName(NULL, _T("MYCOMPUTERNAME\\"), NULL, &SIDLength, NULL, &RefDomainNameLength, &SIDNameUse);
PSID psid = (PSID)new BYTE[SIDLength];
LPTSTR domain = new TCHAR[RefDomainNameLength];
::LookupAccountName(NULL, _T("MYCOMPUTERNAME\\"), psid, &SIDLength, domain, &RefDomainNameLength, &SIDNameUse);
LPTSTR StringSid;
::ConvertSidToStringSid(psid, &StringSid);
::LocalFree(StringSid);
delete[] domain;
delete[] (BYTE*)psid;

Hello,
that looks great. I ignored LookupAccountName because, reading in the msdn, it should be only working with a PDC.
I try this out.
Thanks

Can any body help?
I can successfuly write to the file,
but if I try to append it using the seek,
nomatter what parameters I pass, I always
get an assertion error.
my only soloution is to load the file contents
and then rewrite it fresh again, to get it working
oh dear, what a waste of resources, also my concern is,
from reading it and then writing it in this manor
if a number of users who use my software, there might be a chance
that when writing some recorded information will be lost
due to this manor
but my reckoning is that the file access spped is so fast
anyway that this shouldn't really matter. or does it?
looking for your expert opinion,
thanks

What line of what file is asserting?
"Love people and use things, not love things and use people." - Unknown
"The brick walls are there for a reason...to stop the people who don't want it badly enough." - Randy Pausch

|

inet.cpp
line 918
yellow arrow pointed to ----> ASSERT(m_bReadMode);

So have you looked at line 918 of inet.cpp to see what condition is asserting?
"Love people and use things, not love things and use people." - Unknown
"The brick walls are there for a reason...to stop the people who don't want it badly enough." - Randy Pausch
|
|
|
|
|
ASSERT(m_bReadMode);
I have no clue at all whats this line is doing
|
|
|
|
|
It is asserting that m_bReadMode is non-zero. Apparently it is not. How are you constructing the CInternetFile object?
"Love people and use things, not love things and use people." - Unknown
"The brick walls are there for a reason...to stop the people who don't want it badly enough." - Randy Pausch
|
|
|
|
|
CInternetFile* pFile = (CInternetFile *)m_pFtpConnection->OpenFile("simon.txt", GENERIC_WRITE, FTP_TRANSFER_TYPE_ASCII);
|
|
|
|
|
Why the unnecessary cast?
Have you stepped into either of the CInternetFile constructors to see what m_bReadMode is being set to?
"Love people and use things, not love things and use people." - Unknown
"The brick walls are there for a reason...to stop the people who don't want it badly enough." - Randy Pausch

Hi, Dave
I am quite fresh at this, how do I go about stepping into the
CInternetfile section
cheers
|
|
|
|
|
LONG CInternetFile::Seek(LONG lOffset, UINT nFrom)
{
ASSERT_VALID(this);
ASSERT(m_hFile != NULL);
ASSERT(m_bReadMode);
ASSERT(m_pbReadBuffer == NULL);
// can't do this on a file for writing
// can't do this on a file that's got a buffer
//////////////the above mentioned/////
Is there an alternative
|
|
|
|
|
Also, asserting on m_bReadMode==false indicates that the code
requires read mode - you specify GENERIC_WRITE.
