Yep, that's a serious limitation of GDI+ but it can be easily overpassed by rotating yourself the text:
Graphics* m_pGraphics;
What you have to do is :
1. translate text to origin,
2. rotate,
3. translate back to position,
Let's go:
We create a graphic container to apply transformations
graphicsContainer = m_pGraphics->BeginContainer();
Doing steps 1,2,3 the order of matrix multiplication is important !
m_pGraphics->TranslateTransform(pointF.X,pointF.Y);
m_pGraphics->RotateTransform(-angle);
m_pGraphics->TranslateTransform(-pointF.X,-pointF.Y);
Draw the string
m_pGraphics->DrawString(str, -1, &font, pointF, &sf,&solidBrush);
Fold back transformations by getting out of the container
m_pGraphics->EndContainer(graphicsContainer);

Very thanks friend.
It´s really what I was thinking to do. Thanks for your help!

i am using winmain in my application and i want to restrict that only one instance of the application should run at one time. is there way to restrict it.

A single instance is a "Singleton"
Hello World!!!

Sorry, but a Singleton is to do with having a single instance of a particular class in an application (and is a very useful thing  ), but the question was asking about only ever having a single instance of an application running at a time.

Hi all, I know this is cheeky in the C++ section but pleeease help me!! I need to shave some time off of the compiler generated interrupt code. In the code below (#int_gobal with compiler generated interrupt code within it) this shoul compile then work the same as it previously did but the compiler stops on '03.5', this is the status register bit 5 so i tryed 'BTFSC STATUS,5' but that didnt work either. Im very confused, please help me.
#int_global
isr() { // Will be programmed at location 4
#asm
BTFSC 03.5
GOTO 00A
MOVWF 25
SWAPF 03,W
MOVWF 26
GOTO 00F
........ etc ....
#endasm
}

i duuno much about PICs, but other controlers ... so ... first, why not doing all the stuff in asm ? ... secondly, giving 03 will always work whereas STATUS must be an alias and should be used only if it is defined somewhere as being equal to 03 (like an #include STATUS 03)(check the include files and/or your compiler settings)
Could you post the BTFSC description function ??

Hi !
Just like to know how difficult this is to skin a dialog app such winamp does (must be the 100000th to ask it, but ...  ) ? Someone knows about a _good_ article on that ?
Thanks ...

Hi !
I have a "one euro question" ...
I´d like to know how to allocate memory for a 20x10 "matrix"; I´ve tried foolowing :
int **Table;
*Table=new int[nb_lines];
for(int i=0;i<10;i++)
{
Table[i]=new int[nb_columns];
}
This works - at least it compiles and does something in the app, but it still crashes when in use, so i guess there must be another way to do it .BTW, i do not want to declare another structure or use another thing, i´d really like to know how to do it this way (it´s just for fun)... Anyone knows ?
~RaGE();
|
|
|
|

And this:
int **table;
table = new int*[nb_lines];
for(int i = 0; i < nb_lines; i++) {
table[i] = new int[nb_columns];
}
I think ...

Hi,
I've got a pointer pointing an image (buffer) and I want to display this image in the client area (view)...
How to do this simply ???
Thanks in advance...
Hello World!!!

what kind of "buffer" ?
to display anything in Windows, you've got to convert it to a DIB or HBITMAP first.

I get an image from a frame grabber...
Thus the image comes from a buffer in the SDRam memory. I think it must exist an Object which encapsulate un pointer which pointe to this buffer...
I think... No?

do you have any documentation?
most devices will return a DIB (HDIB, LPDIB, LPBITMAPINFO, etc) or an HBITMAP.

For the moment I use some code and that works... but I don't find that very clean...
BITMAPINFO* m_pInfo; // is a member of the view
void CArchitectureView::SetBitmapInfoHeader()
{
unsigned short max_shade = 256;
m_pInfo = (BITMAPINFO *) malloc (sizeof(BITMAPINFOHEADER) + max_shade * sizeof(RGBQUAD));
m_pInfo->bmiHeader.biBitCount = 8;
m_pInfo->bmiHeader.biClrUsed = max_shade;
m_pInfo->bmiHeader.biSize= 40;
m_pInfo->bmiHeader.biPlanes = 1;
m_pInfo->bmiHeader.biCompression = BI_RGB;
m_pInfo->bmiHeader.biSizeImage = 0;
m_pInfo->bmiHeader.biXPelsPerMeter = m_pInfo->bmiHeader.biYPelsPerMeter = 0;
m_pInfo->bmiHeader.biClrImportant = 0;
m_pInfo->bmiHeader.biWidth = 0;
m_pInfo->bmiHeader.biHeight = 0;
for(int i = 0; i < (int)m_pInfo->bmiHeader.biClrUsed; i++) {
m_pInfo->bmiColors[i].rgbBlue = m_pInfo->bmiColors[i].rgbGreen = m_pInfo->bmiColors[i].rgbRed = i * (BYTE)(256 / m_pInfo->bmiHeader.biClrUsed);
m_pInfo->bmiColors[i].rgbReserved = 0;
}
}
I use this method during the Initialize of the view...
void CArchitectureView::OnInitialUpdate()
{
CView::OnInitialUpdate();
if(m_pInfo == NULL)
SetBitmapInfoHeader();
}
And the OnDraw() methods... pIm is a pointer to the image
void CArchitectureView::OnDraw(CDC* pDC)
{
CArchitectureDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
if(pDoc->ImAff == NULL)
return;
int H = pDoc->MyImList->GetImage(0).GetHeight();
m_pInfo->bmiHeader.biWidth = pDoc->MyImList->GetImage(0).GetWidth();
m_pInfo->bmiHeader.biHeight = -H;
int mode = pDC->SetStretchBltMode(COLORONCOLOR);
void* pIm = (void*)(pDoc->ImAff);
StretchDIBits(pDC->GetSafeHdc(),
0, 0, m_pInfo->bmiHeader.biWidth, H,
0, 0, m_pInfo->bmiHeader.biWidth, H,
pIm, m_pInfo, DIB_RGB_COLORS, SRCCOPY);
pDC->SetStretchBltMode(mode);
}
yeap... It's clean???

that's really about as clean as you are going to get. image drawing is not simple.

In my app I have an IPicture and would like to save this as a gif file (I'm aware of licensing restrictions). However I'm unsure of the best way to go around this? I've found lots of info on other image formats but not this one.
Can anybody shed any light on the best way of doing this please.
Thanks

I added a ListControl, which is working fine (no Owner data though)
i can put text into it, but weird thing is that i get the text backward.
I.e:
original text:
aaaaaaaaaaaaa
bbbbbbbbbbbbb
ccccccccccccccccc
ListControl text:
cccccccccccccccc
bbbbbbbbbbbb
aaaaaaaaaaaa
this is weird, now the code i put text into the listControl is this (a function i did):
static int VList(char Temp[])
{
if (hList3==NULL) return 1;
LVITEM LvItem;
memset(&LvItem,0,sizeof(LvItem));
//============================
LvItem.mask=LVIF_TEXT;
LvItem.iItem=0;
LvItem.iSubItem=0;
LvItem.pszText=Temp;
SendMessage(hList3,LVM_INSERTITEM,0,(LPARAM)&LvItem);
return 0;
}
it get the text and put it into the ListControl, but backwarded..
now, i saw in a MFC example that in order to make it Virtual ListControl, i need to use the "Owner data" property, but if i check it i get no text in the ListControl,can anyone tell me why and how to fix it ??
thank u all,
Ben

You get the text backwards because you insert every new peice of text at position 0 (top of the list). So if you add aaaa at 0 and then add bbbbb at 0, it pushes aaaaaaaa to 1 etc..
Add the item to the end by getting the count of items in the list:
LvItem.iItem = control.GetItemCount() ;

Hallo! I have a problem concerning adding new elements to a CArray with an CArray inside (which is a pointer)
class cl
{
int i;
CArray<int,int> *ptrint;
CString str;
}
CArray <cl,cl> tst;
when I try to Add a new element to tst, first of all I did the following:
cl toinsert;
toinsert.i = 3;
toinsert.str = _T("asdf");
toinsert.ptrint = new CArray<int,int>
toinsert.ptrint.Add(3);
toinsert.ptrint.Add(4); //2 elements insertet in my int-array
tst.Add(toinsert);
well, this works, but actually the memory of the int-array can not be released by
tst.ptrint->SetSize(0);
and with delete it doesn't work too.
Next thougth was that I get memory just for my "toinsert"-thing and .Add will copy the Data - so I deleted the "toinsert"-thing after inserting but then the int-Array vanishes.
after all I tried to do this:
tst.ptrint = new CArray<int,int>;
which has to work normally but it doesn't !!!
Has anybody a good idea how to solve this problem - I'm getting crazy
thanks a lot out there

CArray is a template, you cannot use it that way.
You have to declare it in a way, when compiler will know type to insert into it, e.g:
CArray <cl, cl&> tst;
