Re: how to stop user in entering text in textbox

...and to complete robert answer,

you can do this also thru the resource editor, by setting the right property of your edit box control.

Hello people Rose | [Rose]

,
i have a rather unique problem. in my application i have two tierd property sheets. (on the main dialog i have a property sheet with some pages and on each of the pages i have a property sheet and some pages)
all the property sheets are created at run time and the program wortks fine.

The problem starts when i try to add any control on the base dialog. in case a control is added, the program just doesnt pop any windows (file dialog for example) the whole application just hangs Cry | :((

.

Can somebody tell me as to why this may be happening and what may be the possible solution.

help to convert EXE to DLL while retaining Document View Architecture.

Here’s my problem:
• I have an existing exe application that has Doc/View architecture (say A.exe).
• This needs to be converted into a DLL while retaining Doc/View architecture (say A.dll).
• All the resources and event handlers should reside in the dll.
• The second application (say B.exe) which needs to invoke above (A.dll) DLL also has its own Doc/View classes. The basic idea here is that both A and B should share the same data loaded in memory.
• User should be able to work independently on both A & B, means they should me modeless dialogs.

Thanks,

Do you need to translate sentences or just individual words?
If you need to translate sentences, you'll need to develop an understanding of the grammatical syntax of the language (simple things like putting adjectives before or after nouns need to be sorted out). If you need only to translate individual words, you're basically just going to effectively be looking it up in a database of some kind and replacing the text with whatever you have in your database.

It's almost exactly the same as the morse code program. I gave you a complete solution to that problem - now I suspect I was actually doing your homework.

What errors do you get? Compiler output?

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??
(doesn't work on NT)

something like : can not instantiate abstract interface class.

toxcct5-Mar-06 21:55

5-Mar-06 21:55

what is the exact compiler message ?
on what class does this happen ?

it says that you are instantiating an abstract class.
that means that you are creating an object of a class that either provides no public constructors or have some pure virtual functions.

give us some true helps if you want some feedback. we cannot guess what you're doing wrong without your code, compiler output.
