This is absolut correct. If you wish your image be drawn as background, you draw it in the OnEraseBkgrnd() handler.

Isn't tga an extension for a TARGA image file, is it?

Do you mean that you loaded a TARGA image via Image class and you see nothing on the display?

yes I could not get any display on the device context .
I wrote following code.
Gdiplus::Graphics graphics(hdc);
Gdiplus::Image image(L"test.tga",TRUE);
graphics.DrawImage(&image,0,0,image.GetWidth(),image.GetHeight());
but when I use a bitmap/jpeg etc file it works file i.e.
following code works fine
Gdiplus::Graphics graphics(hdc);
Gdiplus::Image image(L"test1.bmp",TRUE); // just change the file
graphics.DrawImage(ℑimage,0,0,image.GetWidth(),image.GetHeight());

I think Image class is not able to load a TARGA via Image::Image(const WCHAR *, BOOL ), probably you need to use the one accepting a IStream *: Image::Image(IStream *, BOOL ). Unfortunately I have never used Image this way hence I cannot give you any help about. Try also to ask the Graphics forum.

Hello to all,
In my project we are using a FTDI driver to connect a device to computer means after installing FTDI driver when we connect our device to computer it recognize it as a USB device and start collecting data from it. But now problem is that when device is connected to communication port(COM port)1 to 9 i.e. COM1 to COM9 then our s/w start collecting data from device but when we connect device to COM10 or onwards then our s/w can not recognize device and gives error "Please check the serial port connected to your s/w" means you have selected wrong COM port number.My logic is as follows,
if ((miComDev =
CreateFile(ComPortNumber, GENERIC_READ | GENERIC_WRITE,
0,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL |
FILE_FLAG_OVERLAPPED,
NULL )) == INVALID_HANDLE_VALUE )
{
AfxMessageBox("Please check the serial port\nconnected to ECG System");
return ( FALSE ) ;
}
here ComPortNumber contains the COM port number (i.e. COM1,COM2 and like that).above logic works properly for COM1 to COM9 but when we connect our device to COM10 or above it gives above mentioned error.what to do? is there any other method to open the port COM10 and above? can anybody help me plz?
Thanks and Regards,
Anay

Yes, for COM ports above 9, you need to change the string. It should be: "\\\\.\\COM10".

yes cedric, it worked properly.thanks a lot for your valuable support.once again thanks.

Cedric is correct - I found this out by looking on the FTDI website *somewhere*.
His format also works for com ports lower than 10, so I use it all the time now.
I also found that FTDIs D2XX.dll library was far simpler to use for new software than pretending your device is a serial port. The ability to write it as COM9 etc is good for existing code, but is less friendly for new code.
You may also want to look at my article http://www.codeproject.com/KB/system/Drive_Detect.aspx[^] about detecting devices. The article concentrates on drives, but is equally epplicable (out of the blue) FTDI drivers...

Add the mentioned lib to the Source Files folder of Workspace Window.
Come online at:-
jubinc@skype
|
|
|
|
|
On VS2005:
- Select the
Tools->Options... menu item.
On the newly apperaed window, select the Projects and Solutions->VC++ Directories node. - Select the
Library files item of the Show directories for: list box. - Add the path of the folder containing the
psoCode.lib to the directory list
(you can browse for the folder).
Enjoy your library.

You have to add the psoCode.lib folder path to the Library files list.
Once you have done the above try to build and eventually post any error occurred.

A missing or incorrect header file would yield a preprocessor/compiler error, not a linker error.

Hi,
I guess I tried in the subject matter to explain the problem
let me say before I describle the problem that I am using a few of the same headers .h files in both The C and C++
project
In the begining when I was getting unresolved extern __declspec from the link trying to import C symbols
into my C++ project I thought it had something to do with were I specfied my LIB file (I am using VS 2005 )
Linker -> General then the specfic .Lib under Linker -> Additional inputs
Now however I getting the Idea that a part of this problem is that I have C++ project importing C symmbols
When I declare the imports as extern "C" __declspec(dllimport) in the C++ project I resolve a few of the externs
However I still get unresolved ___impl_func
seems __impl is added to C export but linking the C++ project it doesn't see these names
would doing the following when building the C exports in the C++ projects Help
#ifdef __cplusplus
DLL_EXPORT __cdecl telling the C++ compiler that this is C export
Maybe there is simeple soultion to all of this if you know any please Share
Thankx
