(for instance in pictures). Ok, but what if I will destroy picture? Seriously I mean that there is always possibility that someone will destroy the signature. The one thing we can is that we can find out that someone has destroyed or messed in the signature (for example digital signature with message recovery) >just like if you would mimic the signature of your mum for any signed paper >you had to return to people at school. Can you forge digital signature? I bet you won't (and probably nobody at the moment). Of course I mean "modern" digital signature. For example we take some document, put it through some hash function (for example SHA1), encode result of hash function using RSA (with private key of the signer) and put together encoded hash and document. Now everybody can verify the signature, just by making hash from document, decoding encoded hash (with public key of the signer) and comparing this two hashes. If they are different signature is forged. It was simple example, real algorithms are more complex.

Anybody got a tutorial of how to do that? Michel It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to. - TreeBeard Re: Need of a turorial jmkhael1-Oct-02 8:15 jmkhael 1-Oct-02 8:15  http://www.codeproject.com/com/ Search for Dunn and u have bunch of good tutorials!

So the following structure is 4 bytes (or sizeof(int)). I also know that the size will scale based upon the value of said enumeration. However, I need my enum to be 'short' in order to read some binary data into a much larger structure that contains many of these enums? How can I cahnge the size? typedef enum _ALARM_TYPE { LATCHING = 0, SELF_CLEARING } ALARM_TYPE; Ryan Baillargeon Software Specialist Fuel Cell Technologies Inc.

Re: Size of 'enum' Ryan B.1-Oct-02 8:30 Ryan B. 1-Oct-02 8:30  for everyones benefit I am going to post that I have found you cannot change the size of enum under VC++. In some other environments you can. Ryan Baillargeon Software Specialist Fuel Cell Technologies Inc. Re: Size of 'enum' Anonymous2-Oct-02 3:29 Anonymous 2-Oct-02 3:29  Can you do the conversion yourself? By that I mean, if you want the enum to fit into a short then convert it to a short and read/write that. You may need to do some funky casting and/or memcpy'ing, but the effects will be the same and will work on other compilers too How do i set a Radio Button's state in with win32 api's?

Going around in circles.... plus it looks like I need to know HTML - I dont. Any suggestions on the easiest way to write help docs? I do want the tabbed sort of help file window to pop up with Index, Contents etc (like you get with the MSDN). Help! Appreciate your help, ns Re: writing help docs Ravi Bhavnani1-Oct-02 7:13 Ravi Bhavnani 1-Oct-02 7:13  You only need to know a handful of tags to write most of your documentation.

DO you think its up to date? Have you used it? Has the workshop not changed since the book was written?

Appreciate your help, ns Re: writing help docs Ravi Bhavnani1-Oct-02 7:38 Ravi Bhavnani 1-Oct-02 7:38  Works great for Win2K!

Aaron Schaefer1-Oct-02 7:06 Aaron Schaefer 1-Oct-02 7:06  Hi, I need to know how to specify the system color used in a GRAY_BRUSH as an RGB macro. In other words, if I have something like RGB(r, g, b) Then what values should r, g, and b equal to match LTGRAY_BRUSH, GRAY_BRUSH, etc. Are there some defined constants for gray, light gray, etc? Thanks, Aaron Re: What color is gray? Ravi Bhavnani1-Oct-02 7:11 Ravi Bhavnani 1-Oct-02 7:11  In terms of RGB, lt gray is (192, 192, 192), medium gray is (128, 128, 128) and dark grey is (64, 64, 64). Not sure if this information actually helps you. /ravi Let's put "civil" back in "civilization" http://www.ravib.com ravib@ravib.com
