Including DLL's in EXE file

4-Jul-03 1:30

I wouldn't necessarily try to prevent Alt+Tab or Ctrl+Alt+Delete in your program. They should do that on the PC (using system policies to prevent task manager, and setting the shell to your program instead of explorer.exe). To prevent Alt+F4, handle WM_SYSKEYDOWN.

Just a hint, I usually put in a shortcut key (such as Ctrl+Alt+Shift+F12 or something equally obscure) that closes the application but is not documented so that when you need to close it to do upgrades, it's easier Smile | :)

Hi,

I wrote a program (the same program as in my other question in the messageboard), and Vstudio .NET wants to include some DLL's in the exe file --> these will be copied into the application directory (the dir where I installed my software). This works OK, but I need to get rid of those dll's --> they need to be included in the EXE or something like that, because I don't want any dll's on my disk.

Can somebody tell me how to intgrate those dll (all just standard MS dll's) in my exe file?

Thank you in advance,

Boudewijn Ector

Which DLLs?

Depends on what DLLs.

If these DLLs are just standard MS DLLs, perhaps the setup program can manage it to install/update/check them properly into the Windows system directory?

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

There are a couple ways. First of all, if you can, try to link statically. If any of the DLLs are MFC42.dll (or whatever), or MSVCRT.DLL, you can easily link them statically. In fact this would be your only course of action aside from installing them or assuming they are already on the system (both options are dangerous.)

If you link your DLLs implicitly (e.g., using a .lib file), you are screwed. You'll have no choice but to copy the DLL at install time. The only way around tihs is if the provider of the DLL also gave you source code or a library you can statically link. Then you can do that and not need the DLL at all.

If you have a DLL that you call explicitly (e.g., via LoadLibrary), it is convoluted, but possible, to do what you want. I cannot remember the exact code, but the idea is this:
1. Before compiling, in your resouce file, insert the DLL as a resource (make it a custom type, or "FILE" or something.)
2. In your code, Using resource functions, extract that resouce and save it into a temp directory (e.g., call ::GetTempDirectory and save it there.)
3. In your LoadLibrary call, use the path that you extracted it to (temp dir + DLL name.)

Sorry I can't provide the exact code, but it is on my work computer, and I am not about to go into work on a holiday. Big Grin | :-D

Hi,

I'm using VStudio .NET 2003 Enterprise Architect, and I've build a program to convert some files (I did this in managed C++). But I've got a problem:

I need to install my program on network HD (probably on a server), and my collegaes don't want to have to install the software on each of their computers. They just want to be able to run it, or my program. I can install it on the network, so they can just use the .exe.

I don't use register or config files, all the files needed for IO (some input and some output files) are already available on their pc's, and those fiels will be selected using a dialog.

Can you help me making sure nobody needs to install the software (except for me)?

Thank you in advance,

Boudewijn Ector

while (WaitForSingleObject(m_hFunThread,0)==WAIT_OBJECT_0)
{
Some operarions;
}
Can someone tell me the actions of the above sentences?
Thank you!

It will execute 'Some operations' if m_hFunThread is signaled. If m_hFunThread is not signaled, then WaitForSingleObject will return WAIT_TIMEOUT and the program will continue after the while block.

This seems like an ..unusual thing to do.

From your last question, I think you want to do

while(WaitForSingleObject(m_hFunThread, 0) != WAIT_OBJECT_0)
{
   // Whatever here
}

What operations do you need to do while you're waiting? If you're just waiting and don't actually need to do anything while you wait, then use

WaitForSingleObject(m_hFunThread, INFINITE);

to wait until the object is signalled.

Hope this helps,

Ryan

My project is a sub-project. The main project controls my project.
It will call a function(OnClose())When requiring to stop my project.
Herein there exists a problem.
If the main project breaks down my project.
Something wrong will happen considering to one of my functions being running.

So I want to pop up a dialog to warn the user.
If the user still want to stop the project no matter whatever will happen, I will stop my running function,
else I will keep my function going on and let the following block not to be executed until that function has been run out.

OK. In that case, my first suggestion should work Smile | :)

But my entire programme was stopped. Confused | :confused:

Maybe the first parameter is wrong.
Can you tell me what kind of parameter can be used as the first?

My main dialog in my project call the riskful operation, which is a memeber function of my self-defined class.
"m_hFunThread" is one memeber of my main dialog's base class, and it should be a single thread, so my entire programme stopped.

But,every main function in my project is called by using multiple-thread way

What should I do?
Confused | :confused:

What did the WaitForSingleObject() function return? Did it return WAIT_TIMEOUT? You might want to change it from != WAIT_OBJECT_0 to == WAIT_TIMEOUT.

Aleon666 wrote:

Look at the docs for WaitForSingleObject(). There are quite a few types that can be used. I assume hFunThread is the handle to your thread. The function will return WAIT_SIGNAL_0 when the thread completes, and WAIT_TIMEOUT otherwise, unless there is an error, where WAIT_FAILED will be called.

The main project has a release executable programme, I want to step-debug the errors, but I don't know how to DEBUG from the main project to my sub-project.
And so I don't know the returned value.
Do you know the ways?

After I displaced "!= WAIT_OBJECT_0" with "== WAIT_TIMEOUT" the programme had the same result.

As to "docs", your maening is to read some contents in MSDN, isn't it?

Set a breakpoint at that line and just run the entire program in the debugger. It will stop when it gets to that line.

It stopped working at all? Hmmm. Sorry, but I think I've used up all my knowledge on multithreading Frown | :(

I haven't done much.

Yeah, the information on WaitForSingleObject(). It list the handle types that support waiting for.

The main project has nothing but an exe file and my sub-project.
I must run from the exe file.
When I run the entire program in the debugger, there is a dialog popped up, saying that "..\main.exe" does not contain debugging infomation.

Thank you very much!
