is it a CPU or else?
if i use AMD or Cyrix, what is my platform (intel or alpha)??
thanks in advance.

Yes, Alpha is a processor developed by DEC, then sold to Compaq. Compaq then stopped the development of this processor line, so Alpha is more or less dead.
if i use AMD or Cyrix, what is my platform
Intel - both AMD and Cyrix are using Intel's instruction set. AMD defines some extensions.

I have a dll that implements a debug console (i.e. an application can send messages to it during run time) made of a window with a textbox on it. It's set up so that the first call to ConInit creates the window and displays it, but subsequent calls to ConInit simply return TRUE. In this way, the same console is used by several apps. My problem is that if I run 2 or more applications, when I shut down the first one, it kills my debug console. How can I lock the window so it's not destroyed until the last reference to it is gone (and yes, I'm using reference counting, so that's not it). Anyway, here's some of the pertininet code:
HINSTANCE g_hInstance= NULL;
HMENU g_hMenu= NULL;
HWND g_hOwner= NULL;
#pragma data_seg(".SHARED")
HWND g_hWnd= NULL;
HWND g_hTextBox= NULL;
WNDPROC g_hOldTextBoxProc= NULL;
COLORREF g_clrTextColor= RGB(192,192,192);
COLORREF g_clrBackColor= 0;
HBRUSH g_hBrush= NULL;
HFONT g_hFont= NULL;
BOOL g_bShowTime= FALSE;
BOOL g_bShowSourceHwnd= FALSE;
BOOL g_bShowSourceCaption= FALSE;
UINT g_uRefCount= 0;
#pragma data_seg()
BOOL WINAPI DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
switch(dwReason)
{
case DLL_PROCESS_ATTACH:
g_hInstance=hInstance;
g_uRefCount++;
break;
case DLL_PROCESS_DETACH:
g_uRefCount--;
if (g_uRefCount==0)
{
DeleteObject(g_hBrush);
DeleteObject(g_hFont);
SetWindowLong(g_hTextBox, GWL_WNDPROC, (LONG)g_hOldTextBoxProc);
DestroyWindow(g_hWnd);
}
break;
}
return TRUE;
}
LRESULT CALLBACK WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)

switch(uMsg)
{

break;
}

g_hOwner=hWndOwner;
if (!g_hWnd)
{
memset(&wc, 0, sizeof(WNDCLASS));
wc.hbrBackground=(HBRUSH)(COLOR_BTNFACE+1);
wc.hCursor=LoadCursor(NULL, IDC_ARROW);
wc.hInstance=g_hInstance;
wc.lpfnWndProc=WndProc;
wc.lpszClassName="DebugConsole";
if (!RegisterClass(&wc))
return FALSE;
g_hWnd=CreateWindow("DebugConsole",

WS_OVERLAPPEDWINDOW&~WS_MAXIMIZEBOX,

AppendMenu(g_hMenu, MF_STRING, IDM_CLOSE, "Close");

return TRUE;
}
Thanks for any advice.

A shot in the dark: maybe you should use CS_GLOBALCLASS as class style?
Tomasz Sowinski -- http://www.shooltz.com

|
|
|
just a quick simple question.
Do you have to use memfree after your finished with a block you created with memset?
|
|
|
|
|
memset() doesn't create (allocate) memory. Use malloc() instead.

I'm writing a app. that connects to a ftp server and downloads /uploads some files. I also need smb support and the app must also be able to mount a network share and do similar ftp stuff. My first instinct was to use communication pipes. howeevr I need the app to be Win9x compatible too. My next guess is using Winsock.
how do I mount a network share in WinNT?
Any comments/advise?
TIA.

Hi,
I want to show the vertical scroll bar always in the view (derived from CRichEditView) of my MDI application. The problem is, by default the scroll bar is shown only when it is required. But I want to show the scroll bar always, even if there is nothing to scroll in the view. How do I do that. I tried ShowScrollBar, ModifyStyle ...but no result. ( this is in Win 95 machine)

Hi,
I create a thread that run's for quite a long time. I want a "nice" way of terminating the thread from outside it. The only way I know at the moment is by TerminateThread, but this is not recommended. Are there any better ways?
Thanks
Neil

The only 'clean' way to terminate the thread is from the thread itself. It should periodically check for a signal from main thread to end itself - you can implement this strategy using a volatile bool variable. The variable should be initially set to false; when other thread should exit, the variable is set to true.

There is no nice way of terminating a thread outside of it without some collaboration inside the thread (by the way TerminateThread shoud be used only as a last resort when nothing else worked). It is the thread that has to return upon indication.
There are several methods to signal a thread to die:- Setting some variable that the thread polls periodically,
- if the thread is usually hanged on a
WaitForMultipleObjects() (which is a very usual configuration for dispatching of asynchronous events), have an additional event handle for signalling time to die,
- if the thread pumps messages with a
GetMessage loop, post a termination message with PostThreadMessage(idThread,WM_QUIT,0,0), or signal its dependent window to die and have this windows do PostQuitMessage()on WM_DESTROY.
Once you've signaled the thread to die, you can sit down and wait fot it to pass away with WaitForSingleObject(hThread,INFINITE). If however you're not 100% sure your thread is going to behave, you can add a little panic handler just in case:
if(WaitForSingleObject(hThread,10000)!=WAIT_OBJECT_0){
ASSERT(FALSE);
TerminateThread(hThread);
}
CloseHandle(hThread);

Hi,
I am embedding MSWord In my application, using OLE automation.
But when I goto save i get the saveas method is not available as the
document is been editted in another application.
Code As Follows, from the CanCloseFrame(), i did something similar to insert word into the doc/view architecture
CEmbedWordCntrItem* ViewObj;
ViewObj = ((CEmbedWordView*)pFrame->GetActiveView())
- >m_pSelection;
LPDISPATCH lpDispatch = (ViewObj->GetIDispatch());
_Document doc;
doc.AttachDispatch(lpDispatch);
COleVariant covFalse((short)FALSE);
COleVariant vtOptional((long)DISP_E_PARAMNOTFOUND,VT_ERROR);
doc.SaveAs(COleVariant("C:\\DataDoc.doc",VT_BSTR), vtOptional.........)
Cheers

I'm using a function to set a file for saving data. The function requires an LPSTR typr
for the filename parameter. The filename will be retrieved from an edit box in the application
dialog and it is presently type CString. When I build the project I get an error in the setDisk
function that says. "cannot convert parameter 2 from 'class CString' to 'char *'".
How do I fix this?
|

|

if your CString variable is str, do something like this:
yourFunction (firstParametar, (const char*) str);
I vote pro drink ![Beer | [beer]](https://codeproject.freetls.fastly.net/script/Forums/Images/beer.gif)
|
|
|
|
|
You have to cast:
void func(LPSTR s);
CString strx;
func((char *)(const char *)strx);
... or ...
func(const_cast<char *>(static_cast<const char *>(strx)));

Help!
I've got a list box that that wont stop updating itself.
It displays correctly initially, but if it is refreshed(ON_UPDATE)
then it just goes beserk, repeatedly refreshing itself and keeping the rest of the dialog from refreshing.
Anybody had this happen before?
Know how to fix it?
Thanks
Josh

Are you handling any of the notifications from the list box? if you are make sure that they arent firing themselfs... like if you handle LBN_SELCHANGE, dont set the selection withing that handler.
It kind of sounds like something similar is happening to you, thought I'm not sure what ON_UPDATE referes to.

Hi,
My objective is to simply copy a buffer to a file. However,
my program crashes when I attempt to do any CFile operations
(open/read/write/etc...) when I'm inside my ThreadFunction.
My calls work fine when I move it to the main application
thread, but I need to transfer it to a worker thread, and do
its processing in the background.
What am I neglecting to do? Any help is appreciated.
Best Regards,
Thuan

What kind of crash it is? Can you post some relevant code fragments?

Have you declared your CFile Object local to your thread or is it a static global object ?
