hi, below is my on draw...
it works fine as below...
code:
--------------------------------------------------------------------------------
void CEditorView::OnDraw(CDC* dc)
{
CMemDC pDC(dc);
OnPrepareDC(pDC);
CEditorDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here - use pDC
//as the device context to draw to
//
//Set the mapping mode to LOENGLISH
//
pDC->SetMapMode(MM_LOENGLISH);
//
//Convert arguments to coordinates to MM_LOENGLISH units.
//
CSize szTemp;
szTemp.cx = pDoc->GetGridX();
szTemp.cy = pDoc->GetGridY();
pDC->DPtoLP(&szTemp);
//
// then draw the grid lines
//
CRect clipBoxRect;
pDC->GetClipBox(&clipBoxRect);
for(int x = 10 ; x <= pDoc->GetGridX() ; x += 10) {
pDC->MoveTo(x, -10);
pDC->LineTo(x, -pDoc->GetGridY());
}
for(int y = -10 ; y >= -pDoc->GetGridY() ; y -=10) {
pDC->MoveTo(10, y);
pDC->LineTo(pDoc->GetGridX(), y);
}
}--------------------------------------------------------------------------------
it works perfectly fine as below....
now the problem is i wanan add this to my above code
code:
--------------------------------------------------------------------------------
//
//Draw the squares
//
/*for(int i = 0 ; i < 500 ; i ++) {
for(int j = 0 ; j < 750 ; j ++) {
COLORREF color = pDoc->GetSquareColor(i, j);
CBrush brush(color);
int x1 = (j * 10) + 10;
int y1 = (i * -10) - 10;
int x2 = x1 + 10;
int y2 = y1 - 10;
CRect rect(x1, y1, x2, y2);
pDC->FillRect(rect, &brush);
}
}*/--------------------------------------------------------------------------------
when i do this...
all the processing power of the processor is eaten up by the processor....
can someone pls tell me a solution by which i can incorporate the above code to my View's OnDraw such that i can still retain my processing power????
tks a lot...
Have a Super Blessed Day!

It is not advisable to have a lenghty operation like yours within the UI thread because it gets blocked.
Look up worker threads in MSDN.

GetWindowText

|

hi,no,GetWindowText is diseable in CComboBox
|
|
|
|
|
What are you talking about ????? GetWindowText is inherited from the parent CWnd class! So that works !!
Just use this syntax:
CString Buffer;<br />
GetDLGItem(IDC_YOURCOMBO)->GetWindowText(Buffer);
(or use m_YourCombo.GetWindowText(Buffer) if it is a member variable of your class).
And that will work !!

I posted a thread about how to detect cdrw and MO,but it didn't get appropriate answer.I just use the way as showed below to do it.
/****************************************************
BOOL GetDriveGeometry(HANDLE hDevice, PGET_MEDIA_TYPES pMediaTypes)
{
DWORD dwOutBytes;
BOOL bResult;
bResult = ::DeviceIoControl(hDevice,
IOCTL_STORAGE_GET_MEDIA_TYPES_EX,
NULL, 0,
pMediaTypes, MEDIA_INFO_SIZE,
&dwOutBytes,
(LPOVERLAPPED)NULL);
return bResult;
}
*****************************************************
I can get all CD driver(including cdrom and cdrw,but just as CD driver) with GetDriveProperty.The reason why I get cdrw as CD driver because their value of
"pMediaTypes->MediaInfo[0].DeviceSpecific.DiskInfo.MediaType" all is "CD_ROM".
I want to know the driver's r/w attribute by its parameter of
"pMediaTypes->MediaInfo[0].DeviceSpecific.DiskInfo.MediaCharacteristics" ,but result is still "read only".
please give me some suggestion.
thank you.

here is some bit of code to enumerate...
the network printer attribute should be 16 but i m getting 84 value ... WHY ???. sometime i m getting 1108 value for the same network printer....??
code ....---->>
void PrinterRpt9x()
{
BOOL ret1;
printersetting=true;
DWORD i;
PRINTER_INFO_5* pPrint=NULL;
DWORD pcbNeeded=0,pcReturned=0;
HPRINTMUTEX= CreateMutex(NULL,FALSE,NULL);
ret1=EnumPrinters(PRINTER_ENUM_LOCAL,NULL,5,NULL,pcbNeeded,&pcbNeeded,&pcReturned);
//Windows 95: Also enumerates network printers
// because they are installed locally.
pPrint=(PRINTER_INFO_5 *)GlobalAlloc(GPTR,pcbNeeded);
ret1=EnumPrinters(PRINTER_ENUM_LOCAL,NULL,5,(LPBYTE)pPrint,pcbNeeded,&pcbNeeded,&pcReturned);
for(i=1;i<=pcReturned;i++)
{
if(pPrint->Attributes == PRINTER_ATTRIBUTE_NETWORK)
{
_beginthread(printdata9x,0,pPrint->pPrinterName);
}
if(pPrint->Attributes == PRINTER_ATTRIBUTE_LOCAL)
{
_beginthread(printdata9x,0,pPrint->pPrinterName);
pPrint++;
if(pPrint)
GlobalFree(pPrint);
}
}
then i m enumerating the jobs in queue in a thread and creating log file for each print command...
please help in this regard
guide me how to avoid this error ???

I can get the smtp server address from an email address by using DnsQuery() function.But I wonder wether I can get the pop3 server address or not.
If u can, tell me how. Thanks.
|
|
|
|
|
No, the pop3 server may be on a different machine entirely. Typically ISPs name the machine 'pop.something.com', but thats just an arbitrary naming convention rather than a standard.

Thank you first!
Rap off for you,for me,for our human.

Take a look at the Windows Multimedia library of the PlatformSDK, functions like waveInStart, waveInStop, waveOutOpen , waveOutClose

Check
- What is your needed header files
- What is your needed static linked libraries (*.LIB)
- What is your needed dynamic linked libraries (*.DLL)
- Or needed COM or ActiveX object (VC6 has some functions to insert the component into your project) in Project - Add To Project
Most of these stuff are avail in MSDN.
I guess there is no quick trick for that.
Hope this helps

std::ifstream file(@"c:\myFile.txt");
vector<string> myVec;
string line;
while (file.good())
{
getline(file, line);
myVec.push_back(line);
}
something like that.
