try DrawText/DrawTextEx instead of ExtTextOut
-c

Thanks, that's done the job, partly! I am now using:
pdc->DrawTextEx(InternalGetText(), (LPRECT)myRect, DT_CENTER | DT_WORDBREAK, NULL );
Which does multiline and centres the text horizontaly in the rect., but I can't get it to centre vertically.
DT_VCENTER would appear to do this but it is only effective when combined with DT_SINGLELINE, and single line is def. not what I want. Any further ideas?

I have a buffer overrun problem that i am not 100% sure of the best way to fix it. If someone can give me some direction i would appreciate it.
I have the following :
Two structs with fields of different values that i am attempting to StrCpy();
typedef struct _myInfo
{
TCHAR szOwnerLastName[64];
TCHAR szOwnerFirstName[64];
} MyInfo;
typedef struct _otherInfo
{
TCHAR szOwnerLastName[32];
TCHAR szOwnerFirstName[32];
} OtherInfo;
MyInfo* pMyInfo;
OtherInfo* pOtherInfo;
After populating these fields, here is what i find:
If i do a :
StrCpy(pOtherInfo->szOwnerLastName, pMyInfo->szOwnerLastName);
Since MyInfo is bigger than OtherInfo, the above statement basically writes into the OtherInfo's Firstname field.
Is there a nice way to get around this? I cannot change the field sizes for either structure.
Thanks,
cw

Yes, use strncpy() instead. Or use std::string and not worry about it.

Do you have to use raw strings? Why not use std::string or some other string class? What should happen to the bit of the string that can't fit in the smaller buffer?

Sorry for my poor englisch
i hope i can make myself understood
i need a generall help, how to solve this problem
i work with directx sdk 9.0 and visual studio 2005
i have to create a lens (in spectacles).
i got the modell of the lens with all the curves etc.
but:
the lens is made out of colored glass (let us say brown)
so what happens is, that in the thinner part of the lens the brown is not so intense. in the thicker part of the lens the lens is darker, as there is more material.
please help. how to i start to solve this problem

Are you only trying to change the color of the lens, or are you trying to model the refraction (light bending) of the lens? In the case of the color change set the color brown to levels from faint to heavy based on the thickness of the lens. Basically make a texture map to represent the color at each point in the material. Alternately, you can have a fixed color, brown, and vary only the alpha (transmitance) value based on the thickness of the lens.
If the idea is to model both color change and light bending of the glass lens, google ray-tracing, refraction, BRTDF caustics and/or global illumination. http://www.gpgpu.org/cgi-bin/blosxom.cgi/Advanced%20Rendering/Global%20Illumination/index.html[^]

Hi,
thank you for your answer.
no, I only need the colour.
three questions:
1)
can you give me some code for your ideas? i would be glad to pay you for it.
2)
as the thickness and colour can change with every spectacle: how do i create a texture map in my programm, i cannon hold a file for each possibility.
3)
which alpha do you mean? the one of the material, the ampient alpha?
sorry
george

 At least until you saw my rates.... I will try to point you in the right directions for free, but I rarely write code for people anymore, just too much time for too little. Plus I am strictly OpenGL most of the time.

a texture is simply a map of memory with Red Green and Blue in following bytes, sometimes red, green, blue and alpha. Alpha is a number the same as the other colors representing the transmittance of color to a blending function. Since the blendng function is chosen by the programmer, it isn't a cut-and-dry "this is what alpha is, and this is how it works" but you can find many tutorials on alpha blending in OpenGL or DirectX, your choice. Also with the new shading capability of graphics cards, you can write your own blending function to do what ever level of blending you need.

I am using following code to set the picture(.bmp File) in Picture control. But not getting any picture in picture control.
HBITMAP hBitmap = LoadBitmap(hInst,(LPCWSTR)IDB_BITMAP1);
HWND hWndStatic = GetDlgItem(hWndDlg,IDC_pic);
SetWindowLong(hWndStatic,GWL_STYLE,GetWindowLong(hWndStatic,GWL_STYLE) | SS_BITMAP | SS_ICON);
SendMessage(hWndStatic,STM_SETIMAGE,(WPARAM)IMAGE_BITMAP,(LPARAM)hBitmap);
Please help me. Thnx in advance ..

:-D1.if it is NOT mandatory for you to load it in runtime(through code), then, you can map it statically from the properties box of the control.
:-D2.to load it through code, even i have put more efforts but in vain.
:-D3.so at last, i had to design my own active X control to load an image dynamically. but here, i had to provide the path of the bmp say, "c:\\images\\bitmap1". that was ok for me to fulfil my requirement.
:-D4.if this is ok for you, then i dont mind to share that control(.ocx) with you. but keep in touch through my email id, for me to forward it.
:-D5.it would be great, if anybody answers this question, such that, i can use that logic in most of my future programs.
gudluck.

This line is totally wrong
SetWindowLong(hWndStatic,GWL_STYLE,GetWindowLong(hWndStatic,GWL_STYLE) | SS_BITMAP | SS_ICON); refer the definitions of the Static Control Constants in WinUser.h
#define SS_BITMAP 0x0000000E
#define SS_ICON 0x00000003
#define SS_ENHMETAFILE 0x0000000F
#define SS_TYPEMASK 0x0000001F
so by using (GetWindowLong(hWndStatic,GWL_STYLE) | SS_BITMAP | SS_ICON) you are actually setting the style to SS_ENHMETAFILE. use ((GetWindowLong(hWndStatic,GWL_STYLE) & ~SS_TYPEMASK) | SS_BITMAP) instead.
also shouldnt it be MAKEINTRESOURCE(IDB_BITMAP1) and not (LPCWSTR)IDB_BITMAP1 ?

Stop them from what? If you mean disabling, see here.

hi,
u can disable the usb devices, while changing the registry values
the follwing location have the usb device service set to 3.by changing that value 3 to 4. u can desiable the usb device.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor and double click on "start" word it will show value 3 then u can edit.
this implementation can be done through regstry api which is provided by vc++

try uninstalling your new internet explorer or reinstalling the msdn and see.
or better put this post in the OS and system admin forum.

Hit the 'next' button on the forums a few times. This topic has come up 3 or 4 times in the last week. I'm guessing it's part of a homework assignment somewhere...

Take thsame steps you used to display the bitmap, but for a GIF you will need to include extra code to load the .gif file and render each frame to a DC. In the case of animated GIF's you may also want to use a timer.
Search on CP, there are numerous articles concerning loading and displaying GIF files.
