Correct. That is the same thing that I told you (Rickard/CodeCracker) on your earlier post: you can use a MD5 hash, and compare the hashed values to perform matching.
If you will never need to "show" the password to the user (meaning, they can set an initial password, logon with a password, change their password, but never have it shown to them), then using a Digest is a pretty good solution.

Tell me where to read about it!
I've tried MSDN Library but can't find anything about the MD5!

Howdy,
I'm not sure where to even start. I would like to pull and send information to and from other app's.
For example, Yahoo messenger, I would like to pull the text message from their rich edit box and display the same information in my dialog app.. I would also like to type text in my rich edit box and then transfer the info over to yahoo msgr.
Any Ideas on where I should start?
Thanks,
Rob

This question gets asked over and over again. There's a variety of methods, ranging from sockets to named pipes, altough the seemingly most popular method here in CodeProject is to use WM_COPYDATA (check the MSDN for further info).

[Just a thought... Since the OP is trying to communicate with an application that (s)he has no control over (IOW, no knowledge of any open Sockets, Pipes, or what Windows Messages to send), is such a blanket response appropriate? If so, I, as well as others I am sure, would be quite interested in learning about the "variety of methods" available for pushing and pulling data to/from other "closed" applications.]
If the application you are trying to work with does not expose an API for you to use (i.e. it is "closed"), you have your work cut out for you!
For your example, you may be able to use the WM_GETTEXT message (if you can directly target Yahoo's edit control with it) to get the text of the control (but it would likely get a plain text version of the contents, and only up to 64K of it).
But as far as getting any real functionality from it, you might be SOL... nbsp; I am sure that there is a way out there, but not sure about how easy that way is to implement...
Peace!

Yes, if one of the apps is closed, then none of the usual methods for interapp communications will work. I guess I overlooked this and just sticked with the interapp comms idea.
What do the acronyms IOW and SOL stand for?

Thanks for the input! I just started to play around with WM_GETTEXT today, I think that will work for pulling the text from the edit boxes..
I have a question regarding WM_GETTEXT.. how do I point hWnd = to a control? I set hWnd = the title of the other app. (just for testing) and it returned the title of the dialog box. I'm unsure how I can point hWnd = a control..
Any ideas?
Thanks,
Rob

That is part of the problem. You will likely have to enumerate all of the child windows of the target app 'till you find the one you want. You can use the "Spy++" utility to get the HWND (for testing), and see of WM_GETTEXT will work.
As I said above, you have your work cut out for you. What you are trying to do is far from trivial.
Peace!

Upps. Thats exactly what I am trying to do. But I was not succesful. I am using WM_GETTEXT message to get the text in the control but it does not work for all programs. In fact, it works only for primitive windows
Anyway, if you find a good way to implement this, please post it here. So that we can also learn it 
Kind regards

I using PJ Naughter's class to read/write to the registry.
I want to write a password to the registry but it's pretty unsafe to write the password as a simple string that someone can "hack". So I found that a Binary value that is writen to the registry is not shown so that you can't read the password! Or?
How to declare a BYTE and assign it with values like: r4H#sy@
I can't find that possible!? :/ I'vwe tried.. but when creating a account in Outlook 2000 then a password is saved in the registry and it is a binary file that shows weird value but it's the password!
HEEEEEELP!!

How to declare a BYTE and assign it with values like: r4H#sy@
A BYTE is only a byte, a variable holding a value between 0 and 255. Most probably what you'll want to deal with is a BYTE pointer, designed either as BYTE * ot LPBYTE. This is the stuff you have to provide to registry functions storing binary values. Check this snippet of pseudocode:
UINT nBytes=8;
LPBYTE lpData=(LPBYTE)malloc(nBytes);
memcpy(lpData,"r4H#sy@",nBytes);
hklm.WriteProfileBinary(...,lpData,nBytes);
free(lpData); You'd do similarly for retrieving binary contents from the registry (though here you pass a pointer to nBytes instead of the value of nBytes itself, as the function stores there the size of the data copied upon return).

First, are you trying to encode the password somehow, or just store the password in REG_BINARY format instead of a normal string?
If you are looking for the former, instead of using some encryption, I would think about storing MD5 hash values instead. When you want to save the password, save the password's MD5 instead, and when you want to verify an entered password, generate an MD5 hash from it and compare it to the one you saved earlier.
If the latter, the code posted by Joaquín will do that, but with no kind of encryption whatsoever (meaning, it will be trivial to get the password from it).
BTW: If your application is going to use passwords, make sure it can handle someone deleting the password keys!
Peace!

A BYTE is just a typedef for an unsigned char.

...to write a small app that shows up the time on screen.
This time should be visible even in openGL and D3D. Is this possible ? And if yes, how to do that..
tnx in advance, kixx

You want the time up while you play games, don't you ?
No, because going fullscreen in DX will override all other apps AFAIK.

Hi,
I am using a Dialog based application,
When the Main dilaog is displayed i want to create another dialog(modeless dilaog), i used the CDilag::create function but it's not working, i think i have a problem with the second urgument(CWnd*)
what do i missing here?? and what do i have to write in the second urgument???
Thanks

The second argument is the parent window (in your case, probably the main dialog).
It's hard to know what's going wrong with your app. Remember that modeless dialogs must be created on the heap (i.e. with new CYourDialog) or defined as members of the parent window, and never be defined as local variables inside a funtion.

You need to make sure that you call CWnd::ShowWindow( SW_SHOW ) after creation of the non-modal dialog; either in the non-modal dialog's constructor, or directly, after creation.

I need to copy a project dialog from one project to another in Visual C++. There doesn't seem to be an easy way to do this. What am I missing?

Load either project, and then open the other project's RC file in DevStudio. You can then drag and drop between RC files (hold down the CTRL key during the drag to force a copy operation).
You can also just open both RC files and do the same thing.
Peace!

I tried that. When I go to drop the dialog icon into the destination project the icon turns into a "block" icon. I tried a few other things with importing and copying and nothing seems to work. So then I posted this post.

(Did you try both methods?) Explain exactly where you are trying to drop the dialog. Also, are you sure the target RC file (and it's Resource.h file) are not read-only?
Peace!

Perhaps the problem is with using DevStudio. I'm simply using two instances of Visual C++ 6. Is that the same thing?
