The question states.

Write the following code and discuss what exactly results.
enum logical { no, maybe, yes };

I get the enum part, no = 0, maybe = 1 and yes = 2. But what is the 'logical' part? A logical |, or perhaps a logical &

Thanks for a push in the right direction.

It's the name of the set (i.e., type).

As an added bonus, how would your answer change, if at all, if I were to change the statement to:

enum logical { no, maybe = 3, yes };

Are you saying I can replace the word 'logical' with types like int or CString? I don't think that is what you mean.

bonus question no = 0, maybe =3, yes = 4

-------------------------

logical operator &&(logical a, logical b);

No, not at all. The word following the enum keyword is the name of your new type, like animal, position, or vehicle.

Very good. You have a firm grasp on the subject.

my situation :

In my application i have to start another exe. In that other application the user has to make a choice and has to press the button ok or cancel. Now what i want is to receive the choice of the user in my calling app.

Application 1 --> starts up Application 2

In App2 the user choses ok or cancel

Is there a way to return the value from the choice to my App1 ??

Have a look at GetExitCodeProcess().

if it's a dialog app, shouldn't it be:

if(dlg.DoModal == IDOK)<br />
  //DO THIS<br />
else<br />
  //DO THAT

When I make a main window fullscreened, the taskbar sometimes won't hide itself under my window. It does that arbitrarily it seems. Confused | :confused:

I'm doing this right now:

ModifyStyle(WS_OVERLAPPEDWINDOW, 0);
ShowWindow(SW_MAXIMIZE);

Is there a better way to make a window fullscreened?

I have seen similar problems with XP. Try Start->Run->Accessabilty Wizard. Just hit next on all questions. Restart you program. Is the problem still there?

Hello,
I need to show 2 dialog window and I need to show them side by side how can I do that?

David Crow13-Sep-04 7:49

anyone knows of this control?

13-Sep-04 7:49

You've not privided enough information to generate a specific answer. For example, who owns each of the two dialog boxes? Will both need to be active at the same time (i.e., how does the modality of one affect the modality of other)?

Execute an .exe read in memory

Hi,

I just want to execute an .exe program already read by myself in memory, say:

:
uchar *buf = (uchar*)malloc(file-byte-size);
FILE *fp = fopen("test.exe", "rb");
fread(buf, 1, file-byte-size, fp);
// Cool | :cool:

do some specific codes here Cool | :cool:

run-exe-image(buf); // This is what I want
:

Seemingly, I could't find any API function so far to do this.
All execution functions require .exe file name. (e.g. CreateProcess, ShellExecute, spawn..., exec..., what else?)
I have a need to modify some data in the binary image on the fly without using external parameter file nor modified version of the .exe in temporary folder because of security reasons.
Could someone point me out or lead to links?
Thanks in advance.

Probably because one does not exist. This question has been asked many times over the years, and to date, I've never heard of a solution. Good luck.

then you didn't read carefully. I'm sure I've already given an answer to this question. It is possible!
You need to build a custom PE loader. There is one at http://mitglied.lycos.de/yoda2k/[^].
Have a look at section "Code Snippets", the code is called "InConEx 1.0".

Don't try it, just do it! Wink | ;-)

If it works and solve the OP's problem, then great.

i have an app I wrote that stores files in bytes in a SQL Server database. When the user chooses to open one, my program creates a folder in the current directory of my app called 'temp' then I write the bytes to a file and do a shellexecute. It's seamless and very fast. When my app closes, I have a CleanTempFiles() function that goes through that directory and deletes all the files. This may not be what you wanteed, but that's the best a novice like myself can do.;)

Thanks for your reply.
I often do the same kind of things, but this time I can't make use of a temporary file creation as I noted.
Anyway, thanks. Smile | :)
