A problem about scrolling Edit controls in a dialogue

today422008-Oct-07 16:14

I wanna design a programme with a dialogue which has a funtionality of placing some Edit controls in which you can input text.Those Edit controls are laid in a rectangle that can be scrolled with a Vertical Scrollbar.My recent thought is that laying some Edit controls in a picture control and setting a Vertical Scrollbar by myself to scroll that picture control and those Edit controls inside that picture control.
My programming platform is VC6.0.The language is English.My level of ability in programming is round middle.

Hi,

I have a unit testing framework as a console application that generates its output like compilers. (for example: ..\src\cf4.c(23) : fatal error C1083: Cannot open include file: 'is400cfg.h': No such file or directory)

I want to know how I can integrate this tool with Visual Studio IDE in a way to feed the output generated from this tool be feed to IDE. I want to see the outputs of this tool in Errors pane of Visual studio.

Best regard,

stl bind2nd question

Im attempting to use a member function that takes a reference arg as a predicate for the stl findif algorithm. If I make the predicates arg a non reference type the code compiles, if I make it a reference it fails. Can anyone tell me how to get it working with a reference type argument?

I get a bunch of warnings and then

error C2529: '_Right' : reference to reference is illegal

Both versions are below

/********* this compiles ***************/
class A
{
public:
bool test(int i) {return true;}
};

deque<A> collection;

findif(collection.begin(), collection.end(), bind2nd(mem_fun_ref(&A::test), 5));

/*********second version with reference param to test() ****************/

class A
{
public:
bool test(int& i) {return true;}
};

deque<A> collection;

int iVal = 5;

findif(collection.begin(), collection.end(), bind2nd(mem_fun_ref(&A::test), iVal));

One solution is to use boost::bind() like this

find_if(collection.begin(), collection.end(), boost::bind(&A::test, _1, iVal));

c++ file mergesort

basically, I'm having problems with those pests itoa and atoi.

the initial idea was to split a file into N different smaller files, each of them having their filenames sequencial (ie: 1.txt, 2.txt, ... N.txt)

what I have thought is:

[code]
  int i = 1;
...
  while(!inFile.eof())
{ ofstream outFile(i); //obviously, ofstream doesn't let me to do this

    j=1;
    while(j <= instances_per_file && !inFile.eof())
    { inFile >> s;
      outFile << s << endl;
      j++;
    }
    N++;
  }
...
[/code]

currently using cygwin, but solution must be plataform/compiler independent.

any ideas how to convert int to string without itoa and sstream?

sorry if I posted on wrong place.

What's wrong with itoa()? Can you use sprintf() instead?

std::stringstream is the one C++ string stream class. It is bound to be platform independent, and does exactly what you need.

itoa is its ugly little brother from the C-Library. Also standardized.

Why won't you use both? Is your assignment prohibiting that?
What are you allowed to use, if not standardized library routines?

i subclassed CButton class and have a onmousemove in it and i need to set text on my dialog i know it can be done ive done it before but i cant remember now to save my life

void CMyButton::OnMouseMove(UINT nFlags, CPoint point) <br />
{<br />
    if (!m_bOverControl)<br />
    {<br />
        TRACE0("Entering control\n");<br />
		<br />
        m_bOverControl = TRUE;<br />
        Invalidate();<br />
<br />
		if (GetDlgCtrlID() == IDC_STATUS_BUTTON)<br />
		{<br />
			//IDC_DISPLAY_TEXT is the control i need to set text to<br />
		}<br />
		if (GetDlgCtrlID() == IDC_SEARCH_BUTTON)<br />
		{<br />
			MessageBox("hi");<br />
		}<br />
		if (GetDlgCtrlID() == IDC_OPTIONS_BUTTON)<br />
		{<br />
			MessageBox("low");<br />
		}<br />
        SetTimer(m_nTimerID, 100, NULL);<br />
    }	<br />
	CButton::OnMouseMove(nFlags, point);<br />
}

the messagebox works.

Usually it's preferable to send/post a message to the parent
and let the parent set the text. This eliminates the need for the child
to have intimate knowledge of its parent.

Regardless of how you choose to implement this, eventually you'll
probably want to use SetWindowText() to set the IDC_DISPLAY_TEXT
control's text.

Also, what sets your m_bOverControl to FALSE? Is that what the timer is for?
If so, you may want to look into TrackMouseEvent() and WM_MOUSELEAVE
for a more elegant solution to tracking when the cursor leaves a window.

What type of control is it?
What window is the parent of the control?
Is it the same parent as the button's parent?

If you're using MFC then you should be using an MFC object to
wrap the control - CStatic, CEdit, etc.

If you don't use an MFC control object, there's GetDlgItem() to get
a control's HWND given its ID. You need to know the controls parent to
use it, that's it.

Printing array of bitmap files

I need to print an array of 24 individual bitmap files( about 1.5 inch image each) in array of 4X6 directly to the printer on one page. I can print only one file using foll. code. Is there any way I can use a for loop or any other trick to accomplish this? Please help!

void PrintBitmap(LPCTSTR filename)
{
CPrintDialog printDlg(FALSE);
printDlg.GetDefaults();
// Or get from user:
// if (printDlg.DoModal() == IDCANCEL)
// return;
CDC dc;
if (!dc.Attach(printDlg.GetPrinterDC())) {
AfxMessageBox(_T("No printer found!")); return;
}

dc.m_bPrinting = TRUE;
DOCINFO di;
// Initialise print document details
::ZeroMemory (&di, sizeof (DOCINFO));
di.cbSize = sizeof (DOCINFO);
di.lpszDocName = filename;
BOOL bPrintingOK = dc.StartDoc(&di); // Begin a new print job
// Get the printing extents
// and store in the m_rectDraw field of a
// CPrintInfo object
CPrintInfo Info;
Info.SetMaxPage(1); // just one page
int maxw = dc.GetDeviceCaps(HORZRES);
int maxh = dc.GetDeviceCaps(VERTRES);
//Info.m_rectDraw.SetRect(0, 0, maxw, maxh);
for (UINT page = Info.GetMinPage(); page <= Info.GetMaxPage() && bPrintingOK; page++)
{
dc.StartPage(); // begin new page
Info.m_nCurPage = page;
CBitmap bitmap;
// LoadImage does the trick here, it creates a DIB section
// You can also use a resource here
// by using MAKEINTRESOURCE() ... etc.

//for (int ii=0; ii<2; ii++)

if(!bitmap.Attach(::LoadImage(
::GetModuleHandle(NULL), filename, IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE))) {
AfxMessageBox(_T("Error loading bitmap!")); return;
}
BITMAP bm;
bitmap.GetBitmap(&bm);
int w = bm.bmWidth;
int h = bm.bmHeight;
// create memory device context
CDC memDC;

memDC.CreateCompatibleDC(&dc);
CBitmap *pBmp = memDC.SelectObject(&bitmap);
memDC.SetMapMode(dc.GetMapMode());

dc.StretchBlt(0, 0, 2*w, 2*h, &memDC, 0, 0, w, h, SRCCOPY);

// clean up
memDC.SelectObject(pBmp);

bPrintingOK = (dc.EndPage() > 0); // end page
}
if (bPrintingOK)
dc.EndDoc(); // end a print job
else dc.AbortDoc(); // abort job.
}

Sure - any kind of loop will do.

Separate out the code that is page related - Initialization and cleanup.

In between those, loop through the images, rendering them to the appropriate
location on the printer DC.

Does anyone know how what to set in VS2005 so that you can debug a DLL? I know what to do normally, VS2003 was fine but for some reason I cannot debug a DLL in VS2005! I have set the executable to call the DLL from and I have output the debug version of the DLL to the correct path etc,...

I have read somewhere that it is a known issue in VS2005 and you need to install sybols locally.

In the folder where your "debug configuration" goes there should be a .pdb(program debug database) file. Place this file into the same directory you are placing the "debug configuration" dll. Then under Debug -> Attach To Process, select what ever is using the dll file. Set your break points and let her rip.

hi all, i have a class derived from CDialogImpl<>,i want to catch the Message WM_Keydown, and identify if that key is esc then dont close the dialog.
i have managed to do that in MFC application using Pretranslate function but that function is not working in ATL class,
i have tried to override DialogProc() but this function also not called, similaraly other option like CMessage::PreTranslateMessage and but same result these function are not called.
how to get equalent of MFC's PreTranslateMessage() in this class.

Regards.

i override that function but did not worked either.
here was code i was using

static virtual LRESULT CALLBACK DialogProc(HWND hWnd,UINT uMsg,WPARAM wParam,LPARAM lParam);<br />
LRESULT CMiniBubbleDialog::DialogProc(HWND hWnd,UINT uMsg,WPARAM wParam,LPARAM lParam)<br />
 {<br />
 		WriteEventLog1("Proc called");<br />
 		switch(uMsg)<br />
 		{<br />

 			 WriteEventLog1("Mouse is moved");<br />
 			 break;<br />
 		case WM_LBUTTONDOWN:<br />

Maybe override CDialogImpl::GetDialogProc() and return a pointer to your dialog proc.
