being picky, cos i like slim (obfuscated?!?!) code:-
while(submenu->GetMenuItemCount())
submenu->DeleteMenu(0, MF_BYPOSITION);
no need for ">0"
#include <beer.h>
|
|
|
|
|
MSDN says the method returns -1 on error, thats why I tested >0.
-1 would be rated TRUE and so would cause an endless loop (in your code)?

Hi there,
can I draw items of a listbox into a given DC?
I have a rectangle that's an area inside a listbox. Now I need to repaint all corresponding listbox items into given DC (will be a memory DC later for flicker free bitblitting). In the past I simply called:
pMyListBox->InvalidateRect(rect);pMyListBox->UpdateWindow();
...now I want to draw inside the given DC.
How do I call CListBox::DrawItem() manually, or any better alternatives?
Thx for help, Moak

Here is an easy one for ya....
How do I change the dialog size from the code during run time.
I am looking for something like :
<br />
dialog.SetWindowSize(.....)<br />

Try MoveWindow(), or SetWindowPos().

This is almost what I need but the problem is that it looks for x and y and whenever I paint this window it will just to this x and y.
I want to relativly increase the width of the window from wherever it is.
Is there a way to retrive the current x and y ?

GetClientRect() will give you the rectangle of the client area of the window (so left and top will be 0, and right and bottom give you the width and height). Alternatively, GetWindowRect() gives you the position of the window in screen coordinates.

Note that GetClientRect() does omit the nonclient area (I failed because of that lately).... so GetWindowRect() together with ScreenToClient() might be better.

this works for non-client area + client:
WINDOWPLACEMENT wp;
GetWindowPlacement(&wp);
wp.rcNormalPosition.bottom += delta_bottom;
wp.rcNormalPosition.left += delta_left;
wp.rcNormalPosition.right += delta_right;
wp.rcNormalPosition.top += delta_top;
wp.showCmd = SW_SHOW;
SetWindowPlacement(&wp);

Hello buddies,
Does anyone can explain to me about Hashing or Signature ?
About Hashing or Signature in Crypting ...
If anyone has a informarion about those i'll be a good listener

hashing is a one-way encryption of data. it cannot be unencrypted. a good hash algorithm is one where there is no way to extract any information about the input data, based on the output data (the hash).

Hi dear Chris,
Already, I Encrypt/Decrypt the string by CryptoAPI and without using Hashing.
I just want to know what's better ? Using Hashing in Encrypting or not !
Speed is very important in this project.

I mean right now i can encrypt data by CryptoAPI and by using RC4 algorithm.
So, what's reason to use hashing in encrypting ?
|
|
|
|

one major use of hash functions is to sign the data:
data -> hashFunction(key,data) -> hash
then, you transmit the hash with the data. the recipient can apply the same hash function, using the same key that you used, and compare the two hash values. if they don't match, the message is not the one that you used to generate your hash. this is called a Message Authentication Code (MAC).
this is not the same as encryption.

Hello everyone,
I want to update the icon of my app at runtime after checking to see if a certain condition is true. The new icon to use is defined in my resources. I have looked through past posts on this subject and found some information (mostly using UpdateResource), however I have not been able to get it to work. Here is the code I've got so far:
if( bcondition == TRUE){
HANDLE hIcon = LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDR_MAINFRAME),
IMAGE_ICON, 0, 0, LR_DEFAULTCOLOR);
UpdateResource (hIcon, RT_ICON, MAKEINTRESOURCE(IDI_NEWICON),
MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL), NULL,0);
}
I'm probably totally off here (sorry, still a newbie  ), also where should I put this? Does it need to be at a certain point during the creation of the app? Thanks so much!

Im not exactly sure on what you mean by "update" your icon. I am assuming you mean to change the icon on the window of the application itself and not the EXE's icon completely. If this is wrong say so. But anyways to update an icon on the window itself you could do it a varity of ways. If your using MFC you could simply use SetIcon after loading it from the resource using the LoadIcon function. If your talking about doing this in a Win32 application you may have to do it a bit differnt.
If you mean your trying to update the icon for the EXE completely so that even the icon of the .exe file in your folder changes it would be a bit more hard.
For more info feel free to contact me im not sure exactly what your question is my AIM is LiquidIceKnight or vethax0r my MSN is spartacushaxor@hotmail.com (dont email me here) if you only have yahoo my yahoo name is killereaglesoftware, and if you really don't have any of those and must reply to me only by means of email when it would be so much easier to explain through means of chatting feel free to email me. killereaglesoftware@yahoo.com

Yup, you are right in saying I'm trying to update my icon. I don't want to change it completely in the exe, just update it so the user see something different at runtime. I am using MFC, I will give it a shot with the SetIcon and let you know what happens. Thanks so much for your help!
