Hi, im having some luck with returning a string pstr value from a dll to VB
the question is now, how do i pass a string to the dll

it works when i declair the dll
eg. Declare Sub ReadString Lib "mydll.dll" (ByVal Length As string)

LoadLibrary and ...

I have tried to replace the icon in my window with something i did .ico file, it works in normall .exe files but in DLLs the program trying to use the DLL just crashes, so i started thinking is it possible to have a replaced window ICOn in DLL window dialogs?

how about destroywindow_(WindowID()) ?
that should clear up windows

Would my DLLS in purebasic work on a windowsCE?
or would that require a compiler for the ARM processor?

Im a little new, but it worked.

if your still having problems

use

destroywindow_(WindowID(0))

i dont know if it will leave memory leaks tho, i dunno how to look for those

but thats only a bit of it, where are the rest of em?

like events consts, and stuff?

im writing an about dialog box, but i dont know what the constants are

example. the #IDI_Asterisk means the Icon asterisk but where did i find them all?

How do i get an ICON in the window? like they normally do? system control box (top left)

I got a Syntax error! Protected lPSTR.l
[edit]
WORKS!!!!!!!!!!

have you got an example?
for both pb and vb
i dont know how this stuff work at all! i come from a background of BlitzBasic (they dumbed me!)

wow i realy dont know whats going on here

ok.

how do i get a procedureDLL to return the string "Your string is returned"

this is for a VB project

well basically i want to see if i can pass a text file out of the dll

so it would be ASCII, i dont know much about Purebasic.

Its a project i wrote years back, you pass a whole readme.txt and it jumbles up the text file and passes it back

<vb code>

newstring$ = MyFunction(textfromfile ...

How do i make a DLL for a Visual Basic program?
