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.

Check out HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced in the registry.

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.

 I'm really a beginner of this program,visual c++, so I'm loooking for someone that could help me.
I have to draw a pixel on the screen and I have to find its coordinates because then I'll have to move this point using(maybe) a for loop.
Thanks...and sorry for my english

This is a bit unclear. In order to render the pixel on the device, you must know it's x,y values. There shouldn't be any need to find anything.

Solved: The issue had something to do with recursing the end process function. I changed how the recursion worked and everythings fine now!
I'm writing a program to remove certain spyware. To do this it needs to get a filename and path from a clsid, possibly end a process, delete the file, and delete the clsid. The problem is, if it ends a process then the clsid variable goes from storing a clsid (eg. {00000000-0000-0000-0000-000000000001}) to having odd characters like: ↑▼% (I hope those show up. It's a cross, an upside down triangle, and a %).
This *only* happens if the code kills a process. Here's the function that searches the registry after being passed a clsid:
int delClsId(char *clsid)<br />
{<br />
HKEY keyHandle,key2,key3;<br />
char rgValue[1024];<br />
char fnlRes [1024];<br />
DWORD size1;<br />
DWORD Type;<br />
<br />
cout << "Reading key " << clsid << endl;<br />
<br />
if (RegOpenKeyEx(HKEY_CLASSES_ROOT,_T("CLSID"),0,KEY_ALL_ACCESS, &keyHandle) == ERROR_SUCCESS)<br />
{<br />
size1=1023;<br />
RegOpenKeyEx(keyHandle,clsid,0,KEY_ALL_ACCESS, &key2);<br />
cout << "Opening InProcServer32 in key " << clsid << endl;<br />
if (RegOpenKeyEx(key2,_T("InProcServer32"),0,KEY_ALL_ACCESS, &key3) == ERROR_SUCCESS)<br />
{<br />
if (RegQueryValueEx(key3,_T(""),NULL,&Type,(LPBYTE)rgValue,&size1) == ERROR_SUCCESS)<br />
{<br />
sprintf_s(fnlRes,"InProcServer32 is: %s",rgValue);<br />
cout << fnlRes << endl;<br />
delFile(rgValue);<br />
cout << "CLSID is " << clsid << endl;<br />
}<br />
RegCloseKey(key3);<br />
}<br />
<br />
if (RegDeleteKey(key2,_T("InprocServer32")) == ERROR_SUCCESS){<br />
cout << "Removed InprocServer32 Key!" << endl;<br />
} else if (RegDeleteKey(key2,_T("InprocServer32")) == ERROR_FILE_NOT_FOUND){<br />
cout << "Couldn't locate InprocServer32 key." << endl;<br />
} else {<br />
cout << "Failed to Remove InprocServer32 Key" << endl;<br />
}<br />
RegCloseKey(key2);<br />
<br />
<br />
}<br />
else strcpy_s(fnlRes,"Couldn't access system information.");<br />
<br />
RegCloseKey(keyHandle);<br />
<br />
char delKey[45];<br />
sprintf_s(delKey, "CLSID\\%s", _T(clsid));<br />
cout << delKey << endl;<br />
int i = 1;<br />
<br />
do{<br />
i = delRegKey(HKEY_CLASSES_ROOT, delKey);<br />
} while (i == 1);<br />
<br />
return 0;<br />
}<br />
From the function for killing the process I've narrowed the problem down to something that happens in the "if" part of this if/else statement:
<br />
if(TerminateProcess(hProc,0))<br />
{<br />
CloseHandle(hSnapShotm);<br />
CloseHandle(hSnapShot);<br />
CloseHandle(hProc);<br />
FreeLibrary(hInstLib);<br />
return 0;<br />
}<br />
else<br />
{<br />
CloseHandle(hSnapShotm);<br />
CloseHandle(hSnapShot);<br />
CloseHandle(hProc);<br />
FreeLibrary(hInstLib);<br />
return 602;<br />
}<br />
If the process isn't running, or there's no process to kill then there's no problem. Also, I realize usually you'll find dll files here, but I wanted to test how all these things would work together and would love to understand what's going on. I'm pretty new to c++ but have a strong programming background and large working knowledge of the registry. Thanks!

I was trying to retrieve the body of a message using the code below but
It is always returning
MAPI-E-NOT-FOUND:
hr = m_pfldrInbox->OpenEntry(
m_pInbox[msgID].lpProps[0].Value.bin.cb,
(ENTRYID*)m_pInbox[msgID].lpProps[0].Value.bin.lpb,
NULL,
MAPI_MODIFY | MAPI_DEFERRED_ERRORS,
&ulObjType,
(LPUNKNOWN*)&lpMessage);
//MessageBox(0, L"Message Opened", L"", 0);
if (SUCCEEDED(hr))
{
SPropValue * rgMsgprops = NULL;
ULONG rgMsgTags[] = {1, PR_BODY};
ULONG cCount = 0;
// IStream* istream;
ULONG ulNumChars;
// hr = lpMessage->GetProps((LPSPropTagArray) rgMsgTags, MAPI_UNICODE,
&cCount, &rgMsgprops);
hr = HrGetOneProp(lpMessage,PR_BODY,&rgMsgprops);
if (hr == MAPI_E_NOT_ENOUGH_MEMORY)
{
MessageBox(0, L"Not enough memory", L"", 0);
hr = lpMessage->OpenProperty(
PR_BODY,
&IID_IStream,
STGM_READ,
NULL,
(LPUNKNOWN *) &lpStream);
do
{
lpStream->Read(
sBuffer,
255,
&ulNumChars);
// if (ulNumChars >0) printf("%.*s",ulNumChars,szBuf);
}
while (ulNumChars >= 255);
// printf("\n");
hr = S_OK;
}
else if (hr == MAPI_E_NOT_FOUND)
{
//This is not an error. Many messages do not have
bodies.
//printf("Message has no body!\n");
MessageBox(0, L"Message has no body", L"", 0);
hr = S_OK;
}
else
{
//MessageBox(0, "%d", rgMsgprops[0].Value.lpszA, 0);
int x = 0;
do
{
sBuffer[x] = rgMsgprops[0].Value.lpszW[x];
x++;
//MessageBox(0, (LPCWSTR)sBuffer, L"", 0);
//bufferlen = strlen(rgMsgprops[0].Value.lpszW);
}while (((int)rgMsgprops[0].Value.lpszW[x-1] != NULL) && (x <
255));
}
}
If you can tell what is the problem please help

I understand that. You did not indicate which of OpenEntry(), HrGetOneProp(), or OpenProperty() was returning that value.

It is the HrGetOneProp() that is always returning the property tag that I specified. I used the same fuction to retrieve the subject and sender information using PR_SUBJECT and PR_SENDER_NAME property tags and it works. It only fails to get the message body. That is when I use PR_BODY.

Does this or this help?
For the message that is failing, are you sure it has a body?

You should probably check out the HTML Help Workshop from Microsoft. This would be the standard tool used between about 2000-2004. I'm not sure if .NET came out with something different so I apologize if this is not the standard tool used by the masses anymore. I still code native and use the HTML Help Workshop for my released products. For what it's worth...

I've not done help in a very long time, but I seem to recall the need for a .hpj file, a .hm file, and a .rtf file. The Help Compiler will compile these into a .hlp file.

David,
i must agree that the Help Workshop documentation is not very clear when you don't know where to start for a .hlp file.
could you please point out some good tutorials/articles to create one's first compiled help file ?

I'd start with Google, using some good keywords.

Microsoft changed from the dedicated Help file format (generated from RTF using the Help Compiler, hpj file, etc) about the time of Visual Studio 6, I think. All Help is done using the HTML help system these days, I am told.
Having said that, I wrote a Help file a year or two back using the old methods (which I was familiar with), because it was easier than learning about the new HTML Help system.
As far as I remember, VS6 supported traditional HLP, but you could add support for HTML help.

i don't want to create a html help file.could u suggest the procedure to create a rtf file. i know we have to add some footnotes and symbols and save it as a rtf file amd then compile it using help workshop.i want to know how to add footnotes and create a rtf document
Thanks

You can use any text editor (even Notepad) to create an RTF file, but that is a real pain in the butt. I recommend that you ignore any reference that tells you to write stuff like " {\rtf1\ansi\deff0 " - you can do this and work with raw RTF but there is no need to!
One easy way to make RTF files is to use MS Word (or other common word processors) since "Save As" allows you to save files in RTF format.
In Word 2000, creating footnotes is done by Insert menu / Footnote. In the Footnote dialog box, select Custom Mark, and use the "#" (Context name), "$" (Topic name), "k" (keyword), etc as the marking symbol.
If you do a Google search for "authoring winhelp help", you should get a zillion references. For a start, look at the following:
