Hello, I hope the following makes sence to someone!
We have a piece of software which was done before I started with the company
and now I have taken over the installation side of things.
I am reading a registry value in a property called DATABASEPATH. This works
fine except the original programmer set the entire path including the
filename which i don't want, i only want the directory path (so at the
moment we have for example: 'C:\My Folder\MyFile.txt' and what i NEED is
'C:\My Folder\')
I have no idea how to tackle this and I have been playing around with
CustomActions but I really dont know what I'm doing. I have some sample
code from the MS Website which I modified and looks like this...
UINT __stdcall DirectoryFormatter(MSIHANDLE hInstall)
{
TCHAR* szValueBuf = NULL;
DWORD cchValueBuf = 0;
UINT uiStat = MsiGetProperty(hInstall, TEXT("DATABASEPATH"), TEXT(""),
&cchValueBuf);
MsiSetProperty(hInstall, TEXT("DATABASEPATH"), TEXT("C:\\")); // set
the
property
if (ERROR_MORE_DATA == uiStat)
{
++cchValueBuf;
szValueBuf = new TCHAR[cchValueBuf];
if (szValueBuf)
{
uiStat = MsiGetProperty(hInstall, TEXT("DATABASEPATH"),
szValueBuf,
&cchValueBuf);
MsiSetProperty(hInstall, TEXT("DATABASEPATH"),
TEXT("C:\\")); // set the
property
}
}
if (ERROR_SUCCESS != uiStat)
{
if (szValueBuf != NULL)
{
delete [] szValueBuf;
}
return ERROR_INSTALL_FAILURE;
}
delete [] szValueBuf;
return ERROR_SUCCESS;
}
Obviously a function will replace 'C:\\' with the stripped down path (could
probably figure that out).
My problem is getting this to run and change the DATABASEPATH property. The
user is not going to get a choice at to where to install this because it
will be installed into the directory that it finds. Am I over complicating
things? If there is an easier way I would love to hear it because I'm
pulling my hair out now!
I am NOT a C++ Programmer so I have no idea what that code is doing!! Any
help will be greatly appreciated.
Thanks in advance
