Thanks for all the suggestions.. I am going to trace the error codes for CSOcket and see what type of error i am getting from the create function.. I tried to create the socket in my main thread and pass the handle to the thread but the socket in the thread gives me a invalid socket.. anyway, I'll do some more testing, its probably just something dumb on my part..

Thanks!
Rob

Why?? This code block return the "ERROR_INVALID_OWNER"?? Please Help me~~

ive seen a lot of application create .exe from the main application, and not just one, i mean after a serie of choices u can do that.

To make myself clear, im not talking about adding a single exe to the ressource and reading it than writing it in a .exe file.
I meant after a series of tests or choices i want to be able to generate a custom .exe

Hope this is clear enough, and thanks in advance for any tip or help!

QueryDosDevice. Though, I think you can only use a drive letter to get an NT object name, meaning you'll have to loop all drive-letters until you find a match. Frown | :-(

I want to receive some bitmap from client with socket. How i can start?

Start developping the Client server first, then u can just read the bitmpap file and send it to the server and its the job of the server to rewrite the bitmap file !

This is answered in this forum before, you can try search the forum!
But, to send a bitmap you just read the bitmap file in binary mode and then simply send(bitmap_data,...)! Smile | :)

or something! Smile | :)

Updating Resource in Windows NT

Atlence14-Oct-02 6:19

Hi!

I'm using the Win NT UpdateResource API to change the main icon of a program. My code works well if I extract an icon from a module (EXE/DLL) and I replace the destination icon by this one.

Here my code:

<br />
HANDLE	hUpdate;<br />
char*	lpResLock;<br />
HINSTANCE hExe;<br />
HRSRC hRess;<br />
<br />
hExe=LoadLibrary ("c:\\winnt\\explorer.exe");<br />
hRess=FindResource (hExe, MAKEINTRESOURCE (10), RT_ICON);<br />
lpResLock=(char*) LockResource (LoadResource (hExe, hRess));<br />
<br />
hUpdate=BeginUpdateResource ("c:\\winnt\\calc.exe", FALSE);<br />
UpdateResource (hUpdate, RT_ICON, MAKEINTRESOURCE (1), 1036, lpResLock,SizeofResource(hExe, hRess));<br />
EndUpdateResource (hUpdate, FALSE);<br />
FreeLibrary (hExe);<br />

I would now like to do the same thing but instead of extracting an icon from an module, I would like to get the icon from an ICO file.

How can I use UpdateResource API with an ICO file? Confused | :confused:

Thks in advance!

Tempfile access from other process

Hi,

If I create a tempfile with _open (_sopen) and _O_TEMPORARY-flag I can write to this file but I hav'nt access from an other application. Here the complete Code:

int fh = _sopen ("tempfile.ext", _O_BINARY | _O_RDWR | _O_CREAT | _O_TEMPORARY, _SH_DENYNO, _S_IREAD | _S_IWRITE);
int written = _write (fh, (void *) buffer, sizeof (buffer));
StartApplication ("tempfile.exe");
_close (fh);

Is anybody out there with an solution? I hoped, if I close my 2nd Application (he should open the tempfile for read), the system delete my tempfile automaticly.

2. what line does the error message refer to?

Chris,
It looks like he migh have done something like this, maybe??:

typedef vector<CString> vect;

error C2440: '=' : cannot convert from 'const class CString *' to 'class CString *'

Could you be having a problem with a copy constructor or do you not have to deal with those when working with the CString's?

Take a look at this:

You can copy, delete, rename, xcopy, deltree, move files and folders with ease. I believe that's exactly what you are looking for.

CHtmlEditCtrl Control Creation Failed

Hi!

I'm looking for creating a program in which I would like to add a dialog which contains a Html Edit Control like the one we can get by using the Document/View architecture with the CHtmlEditDoc class as the Document Class.

Here a portion of my code:

BOOL CHTMLCDlg::OnInitDialog()
{
CDialog::OnInitDialog();

CHtmlEditCtrl m_HtmlEdit;
m_HtmlEdit.Create ("",0, CRect (0,0,100,100), this, 1);
....

I get the following error:
error C2248: 'CHtmlEditCtrl::~CHtmlEditCtrl' : cannot access protected member declared in class 'CHtmlEditCtrl'

Does anyone could help me?

Thks in advance!

Ummm. It's strange that the dtor is protected, but nevertheless you're doing it wrong, since in this case the control should be dynamically allocated:

BOOL CHTMLCDlg::OnInitDialog()
{
CDialog::OnInitDialog();
 
CHtmlEditCtrl*  m_HtmlEdit=new CHtmlEditCtrl();
m_HtmlEdit->Create ("",0, CRect (0,0,100,100), this, 1);
....

I don't know about your CHtmlEditCtrl (???) but I've tried this with CHtmlView and it works very nice. CHtmlView (like all CView's has the constructor protected)

//in your OnInitDialog

CHtmlView *pView ;
CRuntimeClass *pRtClass = RUNTIME_CLASS(CHtmlView);
pView = (CHtmlView *) pRtClass->CreateObject();
pView->Create(NULL, NULL, WS_VISIBLE | WS_CHILD, rct, this, IDC_STATIC_CTRL);

pView->Navigate2(_T("www.microsoft.com"));
