You are running into scope problems. The CString threadID is going out of scope, and being destroyed, at the end of your OnConnect() method. As a result, the pointer that is recieved by the OnMyConnect() method is no longer valid.

OHHH!! I see what you are saying. That threadId is getting destroyed as soon as I leave the onConnect function.
Okay so how can I keep it in scope until my main app receives the data?
Thanks

I've just started to learn this high resolution multimedia timer. I have a question regarding to timeSetEvent function.
MMRESULT timeSetEvent(
UINT uDelay,
UINT uResolution,
LPTIMECALLBACK lpTimeProc,
DWORD_PTR dwUser,
UINT fuEvent
);
I want my timer to be TIME_PERIODIC (e.g. fuEvent=TIME_PERIODIC). I want to be able to specify: fire the timer at this particular timer
point t0, then repeatedly fire the timer after every n miliseconds.
Is there a way to make timeSetEvent do so? After setting time event, it should wait now.getmilisec() - t0.getmilisec() to be fired, then repeatedly fires the timer every n miliseconds.
The uDelay field seems to only provide the interval, not the actual time point to fire the timer.
Please feel free to correct me if I'm wrong. Thanks in advance for any help.
Regards,

Has anyone made any source code for SATO printer? I'm having trouble setting up the code for printing the label with XP version.
my code shown below: (was made in Borland Builder but its in c++ code though.)
void __fastcall TLabel_Test::btnPrintClick(TObject *Sender)
{
DWORD numsent;
OVERLAPPED overlapped;
char LabelString[500];
char *Port = "LPT2";
strcpy(LabelString, "A");
strcat(LabelString, "V25H380OB");
strcat(LabelString, "20041201152631");
strcat(LabelString, "V25H750XU");
strcat(LabelString, "Mgr: 2130");
strcat(LabelString, "V40H750XU");
strcat(LabelString, "DLL: 1125");
strcat(LabelString, "V80H250XU");
strcat(LabelString, "Print Count > 25000");
strcat(LabelString, "V105H250XU");
strcat(LabelString, "Print Count > 25000 *");
strcat(LabelString, "V130H250XU");
strcat(LabelString, "Print Count > 25000");
strcat(LabelString, "V155H250XU");
strcat(LabelString, "Print Count > 25000");
strcat(LabelString, "V180H250XU");
strcat(LabelString, "Print Count > 25000 *");
strcat(LabelString, "V205H250XU");
strcat(LabelString, "Print Count > 25000");
strcat(LabelString, "V230H250XU");
strcat(LabelString, "Print Count > 25000 *");
strcat(LabelString, "Q1Z");
Retry:
HANDLE hCom =
CreateFile(Port,GENERIC_READ|GENERIC_WRITE,NULL,NULL,OPEN_EXISTING,FILE_FLAG_OVERLAPPED,NULL);
if(hCom == INVALID_HANDLE_VALUE)
{
edtStatus->Text = "Error. Printer Offline";
return;
}
WriteFile(hCom, LabelString, strlen(LabelString), &numsent, &overlapped);
WaitForSingleObject(overlapped.hEvent, 1000);
GetOverlappedResult(hCom, &overlapped, &numsent, FALSE);
CloseHandle(hCom);
if(numsent < strlen(LabelString))
{
edtStatus->Text = "Error. Printer Offline";

I am trying to paint some text in a window and have it change colour when the mouse is over it, I am using the code:
case WM_PAINT:
{
HFONT pOldFont;
char *szBuffer;
CRect rcClient;
PAINTSTRUCT ps;
COLORREF col;
HFONT hNewFont;
BITMAP bm;
HDC hDC = BeginPaint(data->m_hWnd, &ps);
HDC hdcMem = CreateCompatibleDC(hDC);
HBITMAP hbmOld = (HBITMAP)SelectObject(hdcMem,m_biBackground);
GetObject((HBITMAP)>m_biBackground, sizeof(bm), &bm);
BitBlt(hDC, 0, 0, data->m_nWidth, data->m_nHeight, hdcMem, 0, 0, SRCCOPY);
SetBkMode(hDC, TRANSPARENT);
rcClient.DeflateRect(10,20,10,20);
if (m_bMouseIsOver)
{
col = RGB(GetRValue(m_crSelected),GetGValue(data->m_crSelected),GetBValue(data->m_crSelected));
hNewFont = (HFONT)data->m_hSelectedFont;
}
else
{
col = RGB(GetRValue(data->m_crNormal),GetGValue(data->m_crNormal),GetBValue(data->m_crNormal));
hNewFont = (HFONT)data->m_hNormalFont;
}
szBuffer=new char[strlen(data->m_strCaption)+10];
strcpy(szBuffer,m_strCaption);
pOldFont=(HFONT)SelectObject(hDC, &hNewFont);
SetTextColor(hDC, col);
DrawText(hDC, szBuffer,-1,data->m_rcText,DT_CENTER | DT_VCENTER | DT_WORDBREAK | DT_END_ELLIPSIS);
delete[] szBuffer;
SelectObject(hDC, pOldFont);
SelectObject(hdcMem, hbmOld);
DeleteDC(hdcMem);
EndPaint(data->m_hWnd, &ps);
return 0;
}
I can see that it is selecting the correct colour because the variable 'col' contains the right value at the right time.
But the text displayed is always the first colour, I must be missing something simple, any ideas what???

OK guys well im sorta finished with my final project but i cant get it to work CORRECTLY. The program is to have a menu and ask the user to choose betweetn add, subtract, mult and divide. when they choose whatever one it will ask them a simple question. and if they get the correct answer or wrong answer it will ask them again if they want another problem. If they choose yes then it will give em another problem but if they choose no it will go back to the menu. I cant seem when they enter no it keeps say "enter another seed vaule" I want it to go back to the menu. Well here is the code. O and if they enter anything besides Y or N i need it to say sorry that is an incorrect choice. Here is the code:
#include
#include
#include
using namespace std;
int main()
{
int choice; float num1, num2, answer, correct;
char again;
unsigned seed;
do
{
cout << "\n\t\tSimple Math Tutor Menu\n\n";
cout << "1. Addition\n";
cout << "2. Subtraction\n";
cout << "3. Division\n";
cout << "4. Multiplication\n";
cout << "5. Quit The Program\n\n";
cout << "Please enter a choice: ";
cin >> choice;
if (choice <1 || choice >5)
{
cout << "Sorry that is an incorrect choice!"<<endl;
cout <<="" "please="" enter="" another="" choice="" "<<endl;
cin="">> choice;
}
cout<<"Enter a seed value: ";
cin>>seed;
srand(seed);
num1 = 1 + rand() % 10;
num2 = 1 + rand() % 10;
switch (choice)
{
case 1 : do
{
cout << "What is the sum of "<< num1 << " and " << num2 <<endl;
cin>> answer;
correct = num1 + num2;
if ( answer == correct)
{
cout << "Congratulations you are correct!" <<endl;
}
else
{
cout="" <<="" "sorry="" that="" was="" incorrect"="" <<endl;
cout="" "the="" correct="" answer="" was:="" "="" <<endl;
}
cout="" "would="" you="" like="" to="" do="" another="" problem="" (y="" n)?="" ";
cin="">> again;
cout<<"\nEnter another seed value: ";
cin>>seed;
num1 = 1 + rand() % 10;
num2 = 1 + rand() % 10;
}while (again=='y' || again=='Y');
if (again != 'y' || again !='Y')
cout << "Sorry That is an incorrect choice" <

because one affects num1, and another affects num2.
num1 might be different of num2, but only if srand() if called...
why srand(seed) is not called after the cin...  sorry, don't know.

Hey Guys,
I create an empty out-of-process EXE COM which I exposed a HelloWorld interface to display a message box with "Hello".
and I create a client to connect to the COM object and use the interface to execute the message box.
The Client connects fine locally, but I'm having trouble connecting remotely, one the remote machine I'm getting error number 5.not sure what it means.
Any ideas, feedback or if someone has a working sample of this simple scenario I would appreciate it.
Here is the code for my client:
void CTestclientDlg::OnOK()
{
HRESULT hResult;
ITestInterface *pTS = NULL;
COSERVERINFO CoServerInfo;
memset(&CoServerInfo, 0, sizeof(CoServerInfo));
CoServerInfo.pwszName =_bstr_t("\\\\ServerName") ;
// structure for CoCreateInstanceEx
MULTI_QI qi;
memset( &qi, 0, sizeof(qi));
// Fill the qi with a valid interface
qi.pIID = &IID_ITestInterface;
CoInitializeSecurity (NULL, -1, NULL, NULL, RPC_C_AUTHN_LEVEL_CONNECT, RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE, NULL);
hResult = CoInitialize( 0 );
if( SUCCEEDED( hResult ) )
{
hResult = CoCreateInstanceEx( CLSID_TestInterface, NULL, CLSCTX_REMOTE_SERVER, &CoServerInfo, 1, &qi );
if( SUCCEEDED( hResult ) )
{
pTS = (ITestInterface*)qi.pItf;
pTS->SayHello( );
}
else
{
DWORD eCode = HRESULT_CODE(hResult);
CString Err;
Err.Format( "%d", eCode );
AfxMessageBox( Err);
}
}
CoUninitialize( );
}

Hi all,
I am using blowfish algo for string encryption. but it fails to encrypt the plain text in some cases. To solve above problem,
For that i am writing a text in a some file opened in binary mode
and then again reading the buffer from file and sending this buffer to the
encryption function.
1.Is there a better way of doing the same ?
2.How can one convert a simple plain text into binary format?. Also how can i can combine the plain text and binary text?
Thanks in advance.

Hi,
I have some controls in a groupbox, the only way I was able to view the tooltips was when the groupbow was invisible.
I put the groupbox as first control in my .rc file, bust still it didn't worked.
I also tried searching msdn, but couldn't find anything that could solev this.
tnx for your help !!

The groupbox must come after the controls in the Z order and you must make sure that the group box itself does not have a tooltip associated with it.

How do you do that? I searched for that solution too, but I couldn't figure out the SetWindowPos function. (there was another possible candidate function, but I forgot the name)

In the dialog editor you can set the tab order, make the group boxes the last controls in the tab order.
In the rc file, place the group boxes at the bottom.
If you are using SetWindowPos() use HWND_TOP as the hWndInsertAfter parameter.

I know, that was the first thing I've tried... 
I'll try the SetWindowPos again, I'm thinking it could be a combination of things...
tnx, for the reply.

Anything that makes programming more comfortable and faster
I talked with a guy in ICQ about that. He told me
Visual Assist - helps you with the IDE to type common stuff way faster and makes cool visual accentuations
get it here: http://www.wholetomato.com/
CrossBuilder - helps you to very much to reduce the time for compiling c/cpp files
get it here: http://www.crossbuilder.com/
If you have something to add here, it will be cool
