Hi,
I wonder if there is a way to execute a program from memory.
I've read exe-data from resources and I must execute it without writing to disk.
How could it be done?

Not an area I know much about but trying doing a Google search for: Exe Packers or something like that. These are programs that compress Exe's and then decompress them when they are run.

Not a way that I know of. Why are not able to write to disk first?

I'm thinking about simple protection against debugging

 What does debugging an application have to do with anything? And why do you want to be protected from it? If an application has errors, I would think you'd want to know about them.

i have encoded exe-data (flash projector) in resources and i don't want others to get stuff (images etc.) from it...
ok.. it will only protect from simple resource-hackers etc. not from debugging (sorry for imprecision  )

Can you not write it to some temporary folder using an obscure name (i.e., nothing obvious), and then delete it when done? Other than that, I know of no way to run something from memory. It's a stretch, but you might search for something about "injecting code into another process' address space."

As a last resort i will do it with temp folder...
but i can't assume that the person who will have my cd-rom with exe, grant me an access to temp folder...

Why not use SHGetFolderPath() with CSIDL_LOCAL_APPDATA or CSIDL_PROFILE as the CSIDL?

lol forget it, if someone wants to debug it, he will be able to!
Don't try it, just do it!

In Windows, the EXE file is mapped as virtual memory. The os loader and other parts of the os perform this task. The idea of running a program from memory, even if it could be done, would be meaningless.
Not worth spending time over. Remember, using this technique, you could bypass some anti-virus programs, but the good ones out there will catch it anyway...

Greetings All,
I've been burning up all of my time over the past two days trying to debug this. Please help!
I've written a DLL that creates a modeless dialog (in this case allowing the user to watch an aiming video image of a Laser Tracker.) This DLL is used by various client applications including my test app.
I need the user to be able to use the arrow keys to "jog" the Tracker from the dialog. Also, all of the normal dialog keyboard control needs to work (tabbing, typing into CEdit boxes, etc.)
At first, I couldn't even get key messages in the dialog...as soon as a key was pressed (with focus on the dialog), the message came to the client app. I found a way to fix this from MS' website involving having the app call a FilterDLLMsg() func from its PreTranslateMessage(). However, now when a key is pressed in the dialog, the dialog and app freeze.
I spent a long time tracing this freeze and it seemed to be freezing around the MFC code for _AfxFindNextMnem. I was stumped and thought it had to do with a tabstop or group setting for my dialog controls. Then I tried changing the m_pMainWnd = &dlg; line in my client application's InitInstance() to m_pMainWnd = NULL;. (It's a dialog based app.)
That corrected the freeze problem, but now any AfxMessageBoxes() I call from my client app seem to belong to the desktop instead of the main app dialog. There may be other, more serious, ramifications, but I haven't tested any further.
So, I don't want to change the m_pMainWnd = &dlg; if I don't have to, but for now, it's the only way I've found to keep the DLL/app from freezing. Is that safe? I'd prefer a different solution.
Has anyone out there ever seen this type of behavior? Any ideas? My brain is getting all mushy  as I haven't made much progress on this
Thanks,
Justin

If your problem is AfxMessageBox(), dont use it. Use
MessageBox(dlg,"some text",0,0) instead.
The desktop is the parent of the Message Box bcos MFC probably uses the m_pMainWnd, which you set to 0, as the first param to the MessageBox() function.
I dont know why the dialog should freeze, cos i havent tried it yet.

I am using TrackPopupMenu to display a dropdown menu from a toolbar button that has an arrow on the right side. Things are working as I expect. The menu is basically a list of items that my user checks on/off. Someone in the office has seen an application where you can click an item in a menu and the menu stays open so the user can "select" multiple menu items and then click off of the menu to close it...they now want this in my app.
Any ideas on how to keep the menu from closing after someone makes a selection?
thanks in advance

You could try setting a WH_GETMESSAGE hook using SetWindowsHookEx() and intercept WM_LBUTTONDOWN ?

Hi
I need to figure out a way to communicate with an A/D converter and send and receive data bytes from the PC.
Any suggestions and comments are appreciated.
Thanks.

What is the interface in use? USB/ParPort/Serial...what?
If serial/parport, take a good look at the CreatFile() function in MSDN.

Dear Bikram
thanks for your reply. I will refer to the CreateFile() function.
I am using a parallel port interface and linking the A/D converter to the PC through a SCSI cable.
thanks

I have bunch of files in *.cpp format ( written in VC++). Presently i read the data from a text file and run the program. I want to make a GUI ( using MFC or anything else) so that user can enter the data in the GUI and hence the program reads it from there..
Please give any suggestions and ways to do it..

How do I print my voice mail?

Hi,
I'm a newbie working on an MFC app which needs to display a simple text file of results. I have searched google as well as codeproject, but am stumped as to how i can do this.
I am guessing i'll want to derive a class from CRichEditView, and add the text from there, but how do I add text?!
If anyone has any tips, or places i could look for an answer, it would be greatly appreciated.
Thanks,
 Mike

How do you want to display your results...? What kind of results are they?
It would probabbly be much easier to dump your result to a listbox than using a rich edit.

It's just a text file created by our backend that lists concentrations of different elements.
I want to display them similar to notepad, where the user can scroll up and down, to review, and print if desired.
listbox, eh? I'll look into that.
thanks.

Assuming the text is in a variable (e.g., CString), you can simply call the rich edit control's SetWindowText() method.
