Why is search different from TextBox to RichText?

[Paul Breen]

Hello:
I have a modest editor that uses the textbox, and the search function uses common dialogs with the code that someone posted, Christensen, I think. Search works fine with textbox but when I make a version using richtext the search words are never highlighted. Stepping through the code with debug print shows that the problem is that setsel does not show up in the dialog, even though the parameters, or arguments to the function are OK.
Do I need to do something special? I have seen messages that say you need a special message pump for richtext, but I don't understand why.
Secondly, I would like to customize the common file find control. I found c code that says you can modify the find dialog rc file on msdn but can I do this with powerbasic? Eventually, I want to add a number of features to the search dialog.
Should I try to avoid richtext and do what Jose did, use the scintilla control? It seems that there is a lot of examples just trying to understand how he did everything, but I would like to build my own from the 'ground up', well, just because
got to go library time out

I don't have worked much with the Rich Edit control. For a text editor there are better options, such Scintilla.

Secondly, I would like to customize the common file find control. I found c code that says you can modify the find dialog rc file on msdn but can I do this with powerbasic?

Why not?

Modify it, include it in your resource file, compile the rc file, include the resulting pbr file in your application and fill the FINDREPLACE structure with a pointer to that template.

Hey, thanks, but . . .
I' ll try to figure this out later, but only 15 min left of intenet. . .
how do I set a pointer to the pbr resource?
It has to be one of the find sturcture fields, right?
the wifi is out, and the mean libraians log you off here after 50 min.
Happy new year

postscript:

Anybody out there doing scintilla with pb?

should I post questions to the SED forum or here?

[José Roca]

According to the M$ documentation you have to add FR_ENABLETEMPLATEHANDLE to the Flags member of the FINDREPLACE structure, and hInstance to the handle to a module that contains a dialog box template named by the lpTemplateName member.

how do I set a pointer to the pbr resource?

Using the MAKEINTRESOURCE macro or function:

Code Select Expand


FUNCTION MAKEINTRESOURCE (BYVAL wInteger AS WORD) AS DWORD
   FUNCTION = MAK(DWORD, wInteger, 0)
END FUNCTION


As it uses a WORD value, add an identifier before the dialog name, e.g.

Code Select Expand


#define FINDDLGORD 10

Paul,

I can give you the code to do this if you are interested, two RC dialogs and the dialog functions as basic code. This is a bit overkill as its for a rich text editor but it will certainly find and replace words if thats what you are after.

Yeah, thanks, I would apprecite it. Just got back online, school has started. In the meantime I wrote a dialog that searces forward, but you could say it is not feature-rich. I am using richtext so I can show results to the user in color, underlined, or whatever. Would you post a download on this topic?
