I can open image in viewer, display on screen also print using cdc. i think the image is not currupt may be some other issue. I will try with some other images.

i don't want to do it with CDC because i don't want to show any GUI. I wrote this code only to show you that i am able to print with GUI by this code

yes GetLastError is not giving any error. I am not loading any other image before this call.
Is it possible that there is conflict due to multiple included header files? During testing multiple options i included many header files.

Jochen actually wrote this code to show that what is working in GUI mode.
LoadImage is the first call that fails it returned value is null and GetLastError returns 0.
About hidden window, can i use this solution in class library project. Because i am working on a dll that will be utilized by another component. if it works then i can go for any solution for initial release. Please suggest how i can do that

yes you are right. But at that time i am using CBitmap that can be attached to CDC and HDC expects HBITMAP. Following code works fine

CImage frontImage;
frontImage.Load(_T("C:\\Front.bmp"));
CBITMAP bitmap;
bitmap.Attach(frontImage.Detach());
BITMAP bm;
bitmap.GetBitmap(&bm);
CDC memDC;
memDC.CreateCompatibleDC(&dc);
CBitmap *pBmp = memDC.SelectObject(&bitmap);
int w = bm.bmWidth;

initially i printed with gui, displayed image and printed using CDC

CDC memDC;
memDC.CreateCompatibleDC(&dc);
CBitmap *pBmp = memDC.SelectObject(&bitmap);

it worked fine. i am having issues with HDC. I will try also by using XPS as default

0 is returned by GetLastError, In GUI mode i used CDC and selecting bmp worked fine
CDC memDC;
memDC.CreateCompatibleDC(&dc);
CBitmap *pBmp = memDC.SelectObject(&bitmap);

@Jochen BitBlt is returning 1 but i checked LoadImage retuns null HBITMAP.As you said as well actually the problem is with LoadImage, i am not sure what can be the alternative to this

Following is my code and logo is always null and file is available on specified location

HBITMAP logo = (HBITMAP)LoadImage(NULL, szFileName, IMAGE_BITMAP, 0,0, LR_LOADFROMFILE|LR_CREATEDIBSECTION);

@enhzflep i tried both solutions, in first with gdiplus it is printing blank. Then i tried 2nd, here it is printing red border but no image. i tried to check error by GetLastError() but it is 0 every time. can i check at any place that image is loaded to hbitmap or no and is attached to hdc as well?

Thanks a lot, i am trying both options

and what about SelectObject(memHDC, frontBitmap). if there is image in fronBitmap then it should attach image to memHDC? currently it has no effect

I have added another option to my question that i tried. Can you please have a look

yes only CreateDC is successfully and creates dc, other two run without any error. IN select object nothing is assigned to dc and same is with BitBlt

thanks jochen for your help. I tried LoadImage with "LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE"but every time result is same. is there any other option other than LoadImage. I don't have good enough experience in vc++.

I printed same image with GUI application. Image was displayed on form and then i printed using CDC. I am developing a class library project and don't want to display any GUI.

yes you are right but i tried other as well just to try

i tried with all options like back/ forward slash, single double slash

sorry i think i cannot attach pictures here

GetObject has no effect, it do not fetch image. Also LoadImage is returning non null value but it is not valid value and GetLastError returns 0 but. Please view the attached image
