Sorry, I don't have the time, my employer want's me to do other stuff.
But you can find heaps of sources/samples, at CP and other places. Just Google for the function names.

You can use SHBrowseForFolder function instead.

Dear Praveen,
You can convert the bitmap to black & white ( hope you are not inteneded gray scale) using StretchBlt function.
Another way to accomplish the same thing is to SetDIBits. But the first method will be easier.

Check here: Scaling an Image from MSDN[^]

A bitmap can be stored by filling bitmap file header structure and save it using file stream. Just google it, you will get more information

Here is an article from MSDN to store bitmap.[^]

hey all,,,
iam using VC++6.0
i have created an edit control button in my formview page.
i want to feed in the numbers from -10 to +10 in it .....i also want to feed in the numbers like 3.45 or 0.45 etc., with in this range. how do i do it?

I have creeated the member variable as double and specified the minimum and maximum range to be -10 and +10 respectively. when i build the program and type in 3.45, the value gets rounded to 3 aand if i type 3.6, it gets rounded to 4
but i want it as 3.45 only to do further operation/calculation in my code .

can anyone help pleaseeeee?
thanks in advance.

better u create a control variable for the edit control. then usings GetWindowText function, get the text in edit control as string. then convert the string to double using sscanf or some other convertion functions..

i need this value to be user-selectable so that I type in 3.45 on the Formview page.

If i get it as string then how do i select the values .....as they are randomly chosen values.

how do i do it?

sorry i didn't understand....

do u mean u want to limit the values in a range( say from 3-10 t0 4.45 )?

thanks for ur response.
I want the range to be say -10 to +10 but i should be able to select values like for eg., 1.5, 4.6, etc.,

I have created member varaible as double for this and hence can limit the range from -10 to +10 but i cannot choose values like 1.5,7.8 .
if i do , the values get rounded to 2 and 8 repesctively.

these values are to be chosen at randon and during runtime ..
how do i do this?

there is some thing wrong with ur code...

I tried creating a double variable for the edit control. and its works fine.

in my code its not geting rounded..

if i give 1.5, it gives exactly 1.5 in the variable..

How did u examined the value in the variable u created?u debugged?

I use VC++6.0
I created edit control on the formview page and then used class wizard to create the member variable for this edit control and chose it as double.
Now if I compile /build my program, then if i try to type in the edit button as 1.5 it rounds to 2 automatically. It is that I cannot type in values like 1.5 on the edit page.
I dont round it anywhere in my code.
How did u debug?
I am new to this programming n still in the learning curve.
