i want to load a bitmap image from a specified location, at run time.
For example: i want to load the image from the file "bitmap1.bmp" saved on desktop to a control on the UI.

Ok, so what's the problem? What code do you have so far?

to load the bitmap file use something like :

HBITMAP hBitmap = (HBITMAP)::LoadImage(0, lpszFileName, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);

If you want to load bmp files you can use of LoadImage but if you want to load other files like jpg you can use of CImage class and then use of a hbitmap for set it to controls.

doesn't you think, CImage required ample amount of code and inclusion of header file to make it work in vc++.. but i believe it is one of good class provided by MS for image handlling. i believe C# also use same interface!

Yeah CImage has a header file that it gives some memory but I guess maybe he will have problem on next for jpg files so I suggest this class however he can uses of GDI+.

Search for IPictureDisp if you like using COM and search for CEnBitmap class by Dan.G. here.. that would solve your purpose! i feel

So then just use Excel Automation.

But I m not sure this could work in EVc++ 4.0.

priyank

It may not, but given that you wanted to read the file in it's native format, I know of no other solution.

Hi everybody,

in PreTranslateMessage i check if the Shift Key and the Control Key is also pressed
if the user hits a key.

If the key is hit with Shift+Control the message is send to the Control's Parent ( for example from
View to Tab-Control to View to Frame )

If i hit this combination 3 timer while the Shift+Control Key pressed all the time,
the check of Control and Shift pressed (GetKeyState(VK_SHIFT) < 0)
the first time both keys are pressed next time they aren't pressed, the 3rd time they are at new pressed.

It's seriously a KeyState behaviour which creates this sideeffect.

Has anyone an idea?

Big thanks Smile | :)

If you look in the control panel, I think there's an accessibility tab which governs this behaviour. From memory, if you press these keys repeatedly, they stay on. This is to help people who can only operate one key at a time. Disabled people, systems with no actually keyboard, etc.

Iain.

I will check it

Thanks Smile | :)
