Is there a way to test if a user has read or full access to certain registry entries? Will the return value of RegOpenKeyEx tell me this? Thanks!
|
|
|
|
|
|
Would you mind showing how to use this function? I'm using RegOpenKeyEX to get a handle to the key. Since RegGetKeySecurity requires a security descriptor, is there a way to get it from the handle? Thanks!
|
|
|
|
|
The RegGetKeySecurity function retrieves a copy of the security descriptor protecting the specified open registry key.
LONG RegGetKeySecurity(
HKEY hKey,
SECURITY_INFORMATION SecurityInformation,
PSECURITY_DESCRIPTOR pSecurityDescriptor,
LPDWORD lpcbSecurityDescriptor
);
Parameters
hKey
[in] Handle to an open key for which to retrieve the security descriptor.
SecurityInformation
[in] Specifies a SECURITY_INFORMATION value that indicates the <code>requested security information. </code>
pSecurityDescriptor
[out] Pointer to a buffer that <code>receives a copy of the requested security descriptor. </code>
lpcbSecurityDescriptor
[in, out] Pointer to a variable that specifies the size, in bytes, of the buffer pointed to by the pSecurityDescriptor parameter. When the function returns, the variable contains the number of bytes written to the buffer.
The above documentation clearly says how to do it. Did you look up the docs? Look at the statements marked in red.

Possible another way ..
<br />
if(ERROR_SUCCESS != RegOpenKeyEx(...))<br />
{<br />
DWORD LastError = GetLastError();<br />
<br />
TCHAR szBuf[80]; <br />
LPVOID lpMsgBuf;<br />
<br />
FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,<br />
NULL, dw, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),<br />
(LPTSTR) &lpMsgBuf, 0, NULL );<br />
<br />
sprintf(szBuf, "Error %d: %s", LastError, lpMsgBuf); <br />
MessageBox(NULL, szBuf, "Error", MB_OK); <br />
LocalFree(lpMsgBuf);<br />
}<br />

Is there a way to make a combo box accept user input/data that is not listed in the list. For example, I have 10 and 20 in the list, can I have the user type in 80 in the dropdown list? I thought the dropdown style does this? Thanks.

Hello,
I would like to know what is the proper way to use LoadLibrary() when loading DLLs. In my project, it depends on couple DLL files to run. Those DLLs need to sit in Windows\win32\ or the same folder as the executable file. However, I want to put those DLL filew into some fixed place and when my application starts to run, I can load them to the memory. I try to use LoadLibrary() function but I don't know where should I call this function in the code. It is because everytime I start the program, I already get the "missing dll" error and the program get terminated before any code has been run. Any idea about this? Am I missing something?
Thanks!

use LoadLibrary for load your dll and use GetProcAddress for functions in dll
and in the end use FreeLibrary

Colleagues,
I have a quick question.
I would think that the code pointed to by the arrow below would result in the IDR_MAINFRAME menu (and other resources) being displayed when the application starts. However, the IDR_PhotoOneTYPE menu and resources are loaded when the application starts. Is that because it just loads the first document template that is defined? If not, why is that?
Thanks in advance for any information you provide.
<br />
AfxEnableControlContainer();<br />
SetRegistryKey(_T("Local AppWizard-Generated Applications"));<br />
LoadStdProfileSettings(4);
pDocTemplate = new CMultiDocTemplate(IDR_PhotonOneTYPE,<br />
RUNTIME_CLASS(CPhotonOneDoc),<br />
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CPhotonOneView));<br />
if (!pDocTemplate)<br />
return FALSE;<br />
AddDocTemplate(pDocTemplate);<br />
pLWDocTemplate = new CMultiDocTemplate(IDR_MAINFRAME,<br />
RUNTIME_CLASS(CLyghtWayveDoc),<br />
RUNTIME_CLASS(CLyghtWayveFrm),<br />
RUNTIME_CLASS(CLyghtWayveView));<br />
if(!pLWDocTemplate)<br />
return FALSE;<br />
AddDocTemplate(pLWDocTemplate);<br />
<br />
CMainFrame* pMainFrame = new CMainFrame;<br />
if (!pMainFrame || !pMainFrame->LoadFrame(IDR_MAINFRAME)) <----------<<<<<br />
return FALSE;<br />
m_pMainWnd = pMainFrame;<br />
m_pMainWnd->DragAcceptFiles();<br />
EnableShellOpen();<br />
RegisterShellFileTypes(TRUE);<br />
CCommandLineInfo cmdInfo;<br />
ParseCommandLine(cmdInfo);<br />
if (!ProcessShellCommand(cmdInfo))<br />
return FALSE;<br />
pMainFrame->ShowWindow(m_nCmdShow);<br />
pMainFrame->UpdateWindow();<br />
return TRUE;<br />
<br />

Hi,
The application maintains a list(CPtrList) of document templates. When the application starts the document template availalbe at the head of the list is loaded.
The AddDocTemplate adds the template to the tail of the above said list.
So as per ur code... this list is like below
pDocTemplate->pLWDocTemplate

Thanks so much...
So what does the following statement do:
// create main MDI Frame window
CMainFrame* pMainFrame = new CMainFrame;
if (!pMainFrame || !pMainFrame->LoadFrame(IDR_MAINFRAME))
return FALSE;
Again, thanks for your answer.

Hi,
This will be the default menu when no document is opened.
try to add the below line in the InitInstance() and see the difference.
Add the line
cmdInfo.m_nShellCommand = CCommandLineInfo::FileNothing;
above this line in ur InitInstance()
if (!ProcessShellCommand(cmdInfo))
return FALSE;
Bye,
Cool Ju

Hello everyone, this is my first post here.
I have been fighting with a problem for quite some time now, and now i´m running out of time.
I have googled til i almost dropped dead 
Well, to get to the point.
I have been designing a system for measuring times and speeds for use at Drag Racing competitions. im am doing it as my final year project (thesis) at my school, the Swedish Polytechnic in Finland.
Used tools:
Visual Studio 6 pro, Access 97.
VC++ / MFC, ADO.
I have designed a dialog, on this dialog i have a bunch of editboxes. The idea is that the users types a number in one of the boxes. This number is a id for a competitor. i want to fetch data about this competitor and fill the other editboxes with that data. For example the make, model and engine size of the car.
I already added the Microsoft ADO Datacontrol and hooked up a dbcombo to it. That works ok, i can scroll data with the Data control. But this is not the way i want users to enter data. The users have a paper which contains the "ladder" so they just need to enter the number of the lefthand conpetitor and then the righthand.
I tried experimenting with the find method of the Crecordset class, but that is not going very well, as visual studio wont give me the memberfunctions as i usually does.
I have coded a bit of databases in Delphi and i must say that it is much easier But i like C++ and have to stick to it because speed is very important in this case.
How do i accomplish the above?
Please somebody help me out, we are testing on saturday and i don´t want to think about what will happen if i´m not ready 
Thanks in advance!

Hi,
Can anyone supply sample code that can get/set the state of the
"Hide extensions for known file types" check box, which is in control panel "Folder Options".
Many thanks.

Thanks David your advice was very helpful. Although it hasn't entirely solved my problem, which is in code similar to this.
<br />
CFileDialog D;<br />
<br />
if( D.DoModal() == IDOK )<br />
{<br />
CString strFPN = D.GetFileName();<br />
CString strExt = D.GetFileExt();<br />
<br />
CString strFPNandExt = strFPN + strExt;<br />
<br />
}<br />
My problem is that when explorer is hiding file extensions, CFileDialog::GetFileExt() returns a null string.
So what I really need to know is whether there is a way to get the file extension of a file that is selected in CFileDialog, (or maybe anywhere in the shell) when file extensions are hidden.
I don't really want to have a registry value changed and then restored
when CFileDialog::DoModal() has finished its business.
