How to fix Static contol width at run time?

13-Mar-13 3:53

As far as I can ascertain (as suggested previously) this is part of the .NET framework so should not be included in an MFC project. If you are trying to mix MFC with Winforms (C++/CLI) you will have problems.

I already told you before that this DLL was part of .Net and shouldn't even be in an MFC/C++ application (unless you put it there on purpose). You probably made a .Net project inadvertently.

Hi all,

on dialog box i have a static contol i want to fit its width according to its text when dialog box is open or text change .

i use this but the control width is set less than text width..

C++

// get the text dimensions
	CString strText;
	m_label.GetWindowText(strText);
	CClientDC dc(this);
	CFont* pFont = GetFont();
	CFont* pOldFont = (CFont*)dc.SelectObject(pFont);
	CSize sizeText = dc.GetTextExtent(strText);
	dc.SelectObject(pOldFont);

	// get the text area (presume left-alligned text).
	CRect rcText;
	m_label.GetWindowRect(rcText);
	
	CRect dlg_stc=rcText;
	this->ScreenToClient(dlg_stc);
	
	rcText = dlg_stc;

	rcText.right = min(rcText.right, sizeText.cx);

	
	CRect new_rect=rcText;
	m_label.MoveWindow(new_rect);

can anybody help me to do this.

thanks.

I have had a similar issue in the past and used the GetTextExtentPoint32() function. I also found it necessary to add the size of a couple of extra characters as the calculation seems very precise.

this also gives the same width.

try this for the above statement,

C++

rcText.right = rcText.left + sizeText.cx

and try to avoid using unwanted temporary variables, you can simply have as below,

C++

CRect rcLabel;
m_label.GetWindowRect(rcLabel); //get screen co-ordinate for static ctrl
rcLabel.right = rcLabel.left + sizeText.cx; //increase/decrease the rect width
ScreenToClient(rcLabel); // convert screen co-ordinate to client co-ordinate
m_label.MoveWindow(rcLabel); //move the static ctrl to new position

Do your Duty and Don't Worry about the Result

XML

I have downloaded IVT library ( Integrating Vision Toolkit), I made my app dependent on this library ( as DSP project in VC6.0) , I can partially compile the app because I get "permission denied" when I get to #include preprocessor statement.
I have checked the directory permissions and I have grayed out "read only" checked in IVT directory.
All of the sources I used so far said that such   grayed out "read only" checked ( in XP) does not make any difference (?)   when directories are involved.
All of my app directories have that grayed out "read only" checked and I have no problem including   other (OpenCV) libraries.
I am tempted to recopy / re-download the IVT files , but would like to hear from the forum what is going on here.
Appreciate any advise.
Cheers
Vaclav

Addendum
Here is the real code snippet
I must be doing something really stupid.

#pragma message("include IVT ")
#include <Z:\Program Files\IVT\ivt-1.3.19\IVT\src> // fails
#include <Z:\Program Files\IVT\ivt-1.3.19\IVT\src\Calibration> // fails
#include <Z:\Program Files\IVT\ivt-1.3.19\IVT\src\Calibration\Calibration.h> // OK

You cannot include complete directories in C/C++.

You can't include a folder, only a file. If you want to add the folders to the list of places to look for include files, add them to project settings (think it's called "Additional include folders") or in the VC6 Tools-Options.

Re: Bitmap creation from a buffer recived

12-Mar-13 0:26

Hello all!
I'm working on a program in which, I'm receiving the bytes of an image and after storing this creating a bitmap to display.
This is my Main code Please see this..

static char buff[MAX_SIZE];
int num;

//receiving the bytes from a client
num=recv(Socket, buff, sizeof(buff), 0);

// progress the buffer

//ifstream creation
std::ifstream is;

is.open(buff, std::ios::binary);
is.seekg(0, std::ios::end);
num = is.tellg();
is.seekg(0, std::ios::beg);

//reading buffer
is.read(buff, num);

tagBITMAPFILEHEADER bfh = *(tagBITMAPFILEHEADER*)buff;
tagBITMAPINFOHEADER bih = *(tagBITMAPINFOHEADER*)(buff+sizeof(tagBITMAPFILEHEADER));

RGBQUAD rgb = *(RGBQUAD*)(buff+sizeof(tagBITMAPFILEHEADER)+sizeof(tagBITMAPINFOHEADER));

BITMAPINFO bi;
bi.bmiColors[0] = rgb;
bi.bmiHeader = bih;
char* pPixels = (buff+bfh.bfOffBits);

char* ppvBits;

hbitmap = CreateDIBSection(NULL, &bi, DIB_RGB_COLORS, (void**) &ppvBits, NULL, 0);
SetDIBits(NULL, hbitmap, 0, bih.biHeight, pPixels, &bi, DIB_RGB_COLORS);

GetObject(hbitmap, sizeof(BITMAP), &cBitmap);

unable to register COM dll 64 bit

12-Mar-13 1:13

1. Please add <pre> tags around your code so it is readable like:

C++

//ifstream creation	
std::ifstream is;

is.open(buff, std::ios::binary);

2. Please explain what your problem is.

Re: unable to register COM dll 64 bit

12-Mar-13 0:24

We have developed a COM DLL 64 bit on Windows Server 2008 R2 - 64 bit and this dll is successfully register when visual studio 2010 is installed on the machine but when on a fresh machine its unable to register with following error:

module xxxx.dll failed to load
make sure the binary is stored at the specified path or debug it to check for prob with the binary or dependent dll files

After a lot of investigation, we found that if Microsoft C++ runtime 2010 10.0.3019 is installed, then only dll will be registered. Can anyone provide the required list of dependecy. Thanks in advance.

You should probably try the Microsoft Visual Studio website for that information.

You have answered your own question, sort of.

You need the *redistributable* runtime package. Which you deliver along with your own code.

Check the folder of Visual Studio. (Redist)
