Yes, maybe not with those exact methods, but you can edit/format it.

[assumptions]You're using EM_STREAMIN to get text into a rich-edit control[/assumptions]

I don't see how that's going to work - the text isn't in the rich-edit control yet, so won't be accessible through the control.

I suspect the only way to do it is to tell the control that you're giving it RTF and annotate the text with RTF markup - here's the RTF spec[^] Smile | :)

Exactly what I was thinking

I am trying to display a Storage Dump From the Rich Edit

So...... On the left hand side I would have 0000010 the 16 bytes newline
000020

I would like to high light the storage location So...

In the call back function I would probably mark it up with XXXXXX

Once the text is in the Rich Edit Object. I would do A FindText to give me the index of

the current XXXXXX Setsel give it the attributes I want

Then ReplaceSel with the right Storage location number

and DLL creates control on main app's dialog and manages control as main app needs

my problem is:

Do let me know the exact purpose for using static control.

Because the functionality that you require can be done using CStatic, however it is easier to use some other control like CButton and then customize it to use in whatever way you want.

CButton already has Tab and tooltip enabled.

Also to enable tab you need to first set the property tabstop to TRUE(this is FALSE by default for static controls) Then you need to write code to show the focus on the static control.

See the following URL to show tool tip on static control:

How can i create .jpg file programatically

Hi there.

I want to create jpg file programmatically.
Lets say I have some text "Hello", Now I want to create a jpg file that contains this text.

Thanks

So have you bothered to study the JPG file format?

PankajB29-Apr-09 5:24

29-Apr-09 5:24

Not yet. I was mainly looking for some sample code that can do the trick.
Can you please provide some pointers to do the same?

Have you searched the internet and CP? Usually, nobody feels like offering any help to people who are not willing to help themselves. Not to mention you're asking for "the code" to do something that's extremely trivial. Like I said, in my other reply to you, there are two steps to it. Go ahead, give it a try and come back with a specific question if at all.

Two steps:

1. Draw your text to a bitmap.
2. Compress it to JPEG.

I want to do this programatically.
I think you have suggested using some tool may be mspaint.

If you are talking about through the cose itself, then please provide more details in raegrd to the sugegsted steps. Thanks.

I knew you wanted to do it programmatically. Have a look at Drawing lines, shapes, or text on bitmaps[^] and then you'll be left with compressing a bitmap to JPEG. A search must bring up an example, if you ask me.

Have a look at the jpeglib[^] stuff.

IMO, it's not an easy task if you want to do it completely manual.

Like other said, create an in-memory bitmap and save-as jpg with a known API like CImage or something similar.
