Hi,
My problem is that I can't make the size of the toolbar buttons right.
This is my code:
HWND CreateMyToolbar(HWND hWnd)<br />
{<br />
HWND hToolbar;<br />
hToolbar = NULL;<br />
hToolbar = CreateWindowEx(0,TOOLBARCLASSNAME,"MyToolbar",WS_CHILD|WS_VISIBLE|TBSTYLE_TOOLTIPS ,0,0,0,0,hWnd,0,g_hInstance,NULL);<br />
if(hToolbar)<br />
{<br />
SendMessage(hToolbar, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);<br />
TBBUTTON tbb[1];<br />
TBADDBITMAP tbab;<br />
tbab.hInst = HINST_COMMCTRL;<br />
tbab.nID = IDB_STD_LARGE_COLOR; <br />
SendMessage(hToolbar, TB_ADDBITMAP, 0, (LPARAM)&tbab);<br />
<br />
ZeroMemory(tbb, sizeof(tbb));<br />
<br />
tbb[0].iBitmap = STD_FILENEW;<br />
tbb[0].fsState = TBSTATE_ENABLED;<br />
tbb[0].fsStyle = TBSTYLE_BUTTON;<br />
tbb[0].idCommand = IDM_FILENEW; <br />
<br />
SendMessage(hToolbar, TB_ADDBUTTONS, sizeof(tbb)/sizeof(TBBUTTON), (LPARAM)&tbb);<br />
return hToolbar;<br />
}<br />
return NULL;<br />
<br />
}
I've set the IDB_STD_LARGE_COLOR imagelist, but in the result the button image is clipped on the bottom.
Can someone show me how to do this right?
thanks in advance,
Ward

Ok, I figured it out by myself. Finally.

Hello,
Would like to know how the contents of a control (say edit control / text box) can be sent to a printer. I am having a text box which is in a dialog. Normally print is supported for a view. But my requirement is to extract the contents of the control, which is in a VC++ 6.0 dialog and has to be printed.
Will help a lot, if a sample code is supported.
Regards,
Vairamuthu.G.

Use following code:

PRINTDLG pd ;<br />

TCHAR szJobName [64 + MAX_PATH] ;<br />

<br />
pstrBuffer = (PTSTR)malloc (sizeof (TCHAR) * (iCharsPerLine + 1)) ;<br />
<br />
<br />
di.lpszDocName =
<br />
if (StartDoc (pd.hDC, &di) > 0)<br />
{<br />
for (iColCopy = 0 ;<br />
iColCopy < ((WORD) pd.Flags & PD_COLLATE ? pd.nCopies : 1) ;<br />
iColCopy++)<br />

{<br />

iNoiColCopy++)<br />
{<br />
if (StartPage (pd.hDC) < 0)<br />
{<br />
bSuccess = FALSE ;<br />
break ;<br />
}<br />
for (iLine = 0 ; iLine < iLinesPerPage ; iLine++)<br />
{<br />
iLineNum = iLinesPerPage * iPage + iLine ;<br />
<br />
if (iLineNum > iTotalLines)<br />
break ;<br />
<br />
*(int *) pstrBuffer = iCharsPerLine ;<br />
<br />
int iAantalChars = (int) SendDlgItemMessage (hwnd,IDC_TEKSTVELD, EM_GETLINE,<br />

<br />
<br />
TextOut (pd.hDC, 0, yChar * iLine, pstrBuffer, iAantalChars);<br />
<br />
if (EndPage (pd.hDC) < 0)<br />
{<br />
break ;<br />
}<br />
<br />
<br />
}
<br />
}<br />
<br />
free (pstrBuffer) ;<br />
DeleteDC (pd.hDC) ;
This will surely help you.;)
kind regards,

I have function in a class called LoadFile
BOOL Bitmap::LoadFile(const char *FileName)<br />
{<br />
<br />
CFileException e;<br />
<br />
strcpy(m_FileName,FileName);<br />
<br />
}
to which i pass string during the call
const char *FileName= _T("c:\\1.bmp");<br />
BMP.LoadFile (FileName);
there is an error
error: unhandled exception , 0x0000000005 access violation
whats wrong

What is m_FileName?
It seems to be something like:
char* m_FileName; //This should produce the error.
However,
char m_FileName[MAX_PATH];//This should not result in an error.
It is unclear from your post; it could be something else also.
this is this.

What is m_FileName declared as?

It depends on what data type m_Filename is.
If it is of type CString, then I think this function will not work without first exposing the memory buffer (GetBuffer(0) ??).
If the variable is an array of characters, then it should work (unless the destination size is less than the source string).
I Dream of Absolute Zero

change to

::strcpy(m_FileName, FileName);

Ok
I think i got the point
i need to allocate the space for
the destination .
thank you

Hello,
You should beware of the UNICODE problems that your code have when you compile with UNICODE defined. See the following where your problems are:
const char* FileName
= _T("C:\\1.bmp");
To solve this problem, use TCHAR* instead of char* where you want to use the _T macro.
[EDIT]
You should also use the macros from tchar.h[^] so that you use UNICODE functions when you build with UNICODE defined.
[/EDIT]
Hope this helps.

Hey. If m_FileName happens to be a CString, then just do this instead:
mFileName = FileName
instead of using anything like strcpy.
You are LUCKY you got the access violation now and not 10 months from now with 10 million copies of your app in the field

Show me EXACTLY here the m_FileName is defined or declared in his original post?

Since you are using mfc why not use CString and let all this memory allocation for strings automatically be handled for you??

Hai Vikas,

I have a class in which there is a structe
i want to initialize the structre through the constructer .
class xyz{
struct tagBITMAPFILEHEADER
{
WORD bfType; // must be 'BM'
DWORD bfSize; // size of the whole .bmp file
WORD bfReserved1; // must be 0
WORD bfReserved2; // must be 0
DWORD bfOffBits;
}m_BITMAPFILEHEADER ;
xyz()
{
BITMAPFILEHEADER ={0,0,0,0,0};
}
}
I am getting an error
error C2059: syntax error : '{'
error C2143: syntax error : missing ';' before '{'
am i wrong someware

If the code that you post is the real code there is a little error:
vikas amin wrote: xyz()
{
BITMAPFILEHEADER ={0,0,0,0,0};
}
xyz()
{
m_BITMAPFILEHEADER ={0,0,0,0,0};
}
Have a nice code day

Sorry that was not the real code it is not copy pasted
i typed it again .
The real problem is how to initialise the structure .
Can anyone tell me

Why don't use
xyz()
{
m_BITMAPFILEHEADER.bfType=0;
m_BITMAPFILEHEADER.bfSize=0;
m_BITMAPFILEHEADER.bfReserved1=0;
m_BITMAPFILEHEADER.bfReserved2=0;
m_BITMAPFILEHEADER.bfOffBits=0;
}
Because, I don't remember if you could use ={0,0,0,0,0} in that point
Have a nice code day

My favorite,
ZeroMemory(m_BITMAPFILEHEADER, sizeof(m_BITMAPFILEHEADER));
if you want to set everything to 0.
Does not work if a class with complex objects is embedded wihtin the structure, such as a CString, however.
I can't believe how many times I have seen code setting data structure's fields to all zeroes, when there are several dozen fields, instead of block setting the entire element. If I only had a dollar...
