Hi all,
According to MSDN, CDC::DrawText will not alter the width of the CRect given to it when there are multiple lines of text and DT_CALCRECT is specified, only the height. Is this information correct, and if so what is the correct way to specify multiple lines of text? I have my text in a CString object, and I'm trying to break text into lines by sticking \n in appropriate places but the width (i.e. my CRect::right) is being altered, is this not the correct way to separate lines?
If it is the correct way, is there some magic trick I need to do with the DC to stop DrawText from playing with CDC::right? I've done:
pDC->SetTextAlign(TA_LEFT | TA_TOP);
pDC->SelectObject(m_FontMain);
The bad code:
pDC->DrawText(strComm, rcComm, DT_CALCRECT | DT_WORDBREAK | DT_LEFT | DT_NOPREFIX);

I think that you are on the right track, however if you look at the description for the DT_WORDBREAK flag this is what it says:
Breaks words. Lines are automatically broken between words if a word would extend past the edge of the rectangle specified by the lpRect parameter. A carriage return-line feed sequence also breaks the line.
So I would try using "\r\n" to insert line breaks rather than just "\n".
Good Luck

Hi! I'm new using CListCtrl and i've been reading some articles how to sort it's columns in the Report mode.
I've a class derived from CHeaderCtrl que does it, but i must pass two arguments, the iSubItem of the column and if i want to sort ASC or DESC, i'm doing like this:
void CExeptions::OnColumnclickCombo1(NMHDR* pNMHDR, LRESULT* pResult)
{
int iB=0;
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
LVITEM lvi;
LVCOLUMN col;
col.mask = LVM_GETCOLUMN;
ListCtrl.GetItem(&lvi);
iB=col.iSubItem;
m_headerctrl.SetSortImage(iB, true);
*pResult = 0;
}
but i can't get the value of the iSubItem.
What am i doing wrong?
Thank you for your time
|
|
|
|
|
sorry, i miscopy the line iB=col.iSubItem;, its iB=lvi.iSubItem;
unfortunally, that was not the problem

I just opened win32 application and this code.
char *l1;
l1=(char *)malloc(sizeof(10));
strcpy(l1,"suresh");
MessageBox(NULL,l1,"value",MB_OK);
free(l1);
When i run the program,run time error happens.
why ?
|
|
|
|
|
sizeof(10) returns actually sizeof(int). Write:
l1=(char *)malloc(10);
|
|
|
|
|
Actually, one should write l1 = (char*)malloc (10 * sizeof (char));

Be a bit more precise, what do you mean by:

I mean such as a metal thead.
What I do now is get a bmp which to be the TextureBrush.
It works find when I draw a horizontal line. but when that's not the horizontal one. It looks bad.
What should i do?

Sure - you can draw whatever you like. Just draw with some perspective.

Well, im trying to write this RC4 encryption class... but its not working properly.... And I cant find the bug.... Can you?
class CEncrypt
{
int m_sBox[256];
public:
CEncrypt() {}
~CEncrypt() {}
void SetKey(char *sKey, int iKeyLen)
{
int i, j = 0, k;
for (i = 0; i < 256; i++)
m_sBox[i] = i;
for (i = 0; i < 256; i++) {
j = (j + m_sBox[i] + sKey[i % iKeyLen]) % 256;
k = m_sBox[i];
m_sBox[i] = m_sBox[j];
m_sBox[j] = k;
}
}
void Encrypt(char *sBuffer, int iBufferLen)
{
int sBox[256], iOffset, i = 0, j = 0, k;
memcpy(sBox, m_sBox, sizeof(m_sBox));
for (iOffset = 0; iOffset < iBufferLen; iOffset++) {
i = (i + 1) % 256;
j = (j + sBox[i]) % 256;
k = sBox[i];
sBox[i] = sBox[j];
sBox[j] = k;
sBuffer[iOffset] = sBuffer[iOffset] ^ (sBox[(sBox[i] + sBox[j]) % 256]);
}
}
};

Not without descriptions of what the code is supposed to do, and what it actually ends up doing.

This it?
<br />
TVS_RTLREADING <br />
Version 4.70. Causes text to be displayed from right-to-left (RTL). Usually, windows display text left-to-right (LTR). Windows can be mirrored to display languages such as Hebrew or Arabic that read RTL. Typically, tree-view text is displayed in the same direction as the text in its parent window. If TVS_RTLREADING is set, tree-view text reads in the opposite direction from the text in the parent window. <br />
Just a suggestion (if you haven't already tried. Just go into Visual Studio help and search for the object (in this example CTreeControl)
