Hey,

you can use all these Libraries for opening the image format that u like to open on your viewer:

cximage.lib
j2k.lib
jasper.lib
jbig.lib
Jpeg.lib
png.lib
Tiff.lib

and also you may have to use opengl at some point, for that u can use these libraries :- "zlib.lib opengl32.lib glu32.lib"

Use GDI+ for tif/jpeg/gif. You need a third party library for other formats.

Use FreeImage (it's a free image processing library available with source code on SourceForge.

Buttons in Macros

As part of a macro, I need to copy the formatting, formulas, and buttons with their assigned macro's of one worksheet on a new sheet.

I've got most of the way there, but when it comes to duplicating the macro buttons (I have been copying and pasting them) the visual code says

ActiveSheet.Shapes("Button 15").Select

but this creates a problem because the future buttons won't always be number 15.

Any ideas so that the macro will apply to all future buttons?

P.S. Im used to working in visual studio 6.0, but sometimes i work in .NET 2003, when in .NET 2003 how do i like open the wizard thingy, where i can like add events (like PreTranslateMessage etc)

  WINDOWPLACEMENT *lpwndpl  // position data<br />

It will go in run loop (for new msg)

The control will end up back in CWinApps message loop.

Have you tried putting a break point near the end of your function, and see exactly where the fault occurs?

*What* is the error?

One fault I had with message functions is getting the parameters wrong, and this gave me no error in debug, and a stack over flow error in release builds.

If you use ON_COMMAND, then make sure your command handler is:

void OnMyButtonPressed ();

otherwise you can have problems.

Hi
I am making an application in vc++ (a modal dilog based app...)
but in my form focus is not set by enter key.

I am using tab key for moving focus from one edit box to another.

can any one tell be how to set the focus by enter key. So when we press
enter key focus move to another object automatically

Regard's

Do you understand that this is not compatible with how Windows programs work in general? The Enter key is not a navigation key - it is a selection key, which (on a dialog) will result in the automatic selection of the default button (usually the OK button).

Doing this will be very confusing to your users. Microsoft has detailed guidelines specified for the Windows user interface - see MSDN for more details.

TAB..Simple question.. [modified]

Hello..

This is very simple question but i dont know how to solve it.I am just beginner in this field so please help me.

In my application..I want some input(binary)..

like..

Enter Input Value:<br />
<br />
SEL    Cx0     XOR    D1<br />
1        1        0      1

Here how i can enter 1101 so it will automatically enter Tab button??ie after entering 1(input for SEL),next cursor will be at Cx0( after 8 tab from SEl) and same way for all other input.

Second question is..How can i enter input as a only "Single char"..ie after entering single char(for exam.. 1) then next cursor point will be at Cx0 input point..

Thanks

Dear

Enter Input Value:

SEL Cx0 XOR D1
1 1 0 1

please mention it.

you wants to take input in Edit Box.

if you are using the Edit Box then two ways

1. create your Control dervied from CEdit and handle all input in EN_CHANGE there bcoz u have to take care of binary
also.

2. handle EN_CHANGE od Edit control in Dialog Box.

What is the difference between map and set AND multimap and mutiset

Hey, are you collecting info for the enemy? Big Grin | :-D

From MSDN multimap reference:

<br />
Unlike template class map, an object of template class multimap does not ensure that key_comp()(x.first, y.first) is true. (Keys need not be unique.)<br />

The same diffrence holds for set, multiset pair.

Re: STL basica

excerpt of MSDN documentation for map:

<br />
The template class describes an object that controls a varying-length sequence of elements of type <big>pair<const Key, T></big>. The first element of each pair is the sort key and the second is its associated value.<br />

excerpt of MSDN documentation for set:

<br />
The template class describes an object that controls a varying-length sequence of elements of type <big>const Key</big>. Each element serves as both a sort key and a value.<br />

Why don't you make a little effort to read documentation, before posting?
