Re: How to tell whether explorer is hiding extensions for known file types ?.

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 />
    // Do stuff here with strFPNandExt...<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.

Hey! I have a chip card reader and some tools with it. this is the reader >>> http://www.chipdrive.de/cgi-bin/edcstore.cgi?user_action=list&category=Produkt;02_L%F6sungen;04_SC%20Tools;05_Screenshots

4th picture is where i should be programming and editing script... i think the script is in pascal language but some friend say that it could be programmed ba C++ too. Well i don't know really nothing about this....... i got this in school and have to done this by friday.
what i have to do is to programme some program which would do something like: showing my grades...
its like that... when you put chip card in reader it should pop-up new window when i would enter code... and another window would open where i would see my grades.... i would really need that!!!! please someone help me!!!!!!!!!

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 />
				//MessageBox(NULL,fnlRes,"File Delete", MB_SYSTEMMODAL|MB_ICONINFORMATION);<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 />
			//MessageBox(NULL,"Removed key!","Key", MB_SYSTEMMODAL|MB_ICONINFORMATION);<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 />
			//MessageBox(NULL,"Failed!","Key", MB_SYSTEMMODAL|MB_ICONINFORMATION);<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 />
  // process terminated<br />
	CloseHandle(hSnapShotm);<br />
	CloseHandle(hSnapShot);<br />
	CloseHandle(hProc);<br />
	FreeLibrary(hInstLib);<br />
  return 0;<br />
}<br />
else<br />
{<br />
  // Unable to terminate process<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!

MAPI application problem

msolh9-May-06 6:08

9-May-06 6:08

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.

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...
