how can i free memory use by a static linked dll-function. The problem:
i call dynamic an dll function(1). This function call an static linked dll function(2). Now when I try to free the dynamic libary (FreeLibary) I get an errorcode (GetLastError = 6). I think there is a problem with the linked function....

Error 6 = ERROR_INVALID_HANDLE.
Do you have something like:
HMODULE hModule = LoadLibrary(...);
if (NULL != hModule)
{
fp = GetProcAddress(hModule, ...);
if (NULL != fp)
(fp)(function params here);
FreeLibrary(hModule);
}
|
|
|
|
|
Yes, in my application i use a dynamic call like yours....
But in my dll (first dll) i use a static linked dll (second dll, called from first dll)

It helps to use common terminology when describing a problem. Implicit linking is done at link time. Explicit linking is done at run time via LoadLibrary(), GetProcessAddress(), and FreeLibrary(). In the case of the latter, be aware of a hazard (from MSDN):
If the DLL has a DllMain() entry point function, the operating system calls the function in the context of the thread that called LoadLibrary(). The entry-point function is not called if the DLL is already attached to the process because of a previous call to LoadLibrary() with no corresponding call to the FreeLibrary() function. Explicit linking can cause problems if the DLL is using a DllMain() function to perform initialization for each thread of a process because threads existing when LoadLibrary() (or AfxLoadLibrary()) is called will not be initialized.

That's the problem. You can free DLL's that you load with LoadLibrary by using FreeLibrary, but libraries that are implicitly loaded (e.g., you don't call LoadLibrary, you just have your DLL linked into your application) are, AFAIK, always loaded.

hi,
i started a little project and have little knowledge of c++ yet.
can someone explain me the basic steps to get access to the memory area of a certain process and write a few bytes, please?
i'm on win2000 here, but it would be nice if it works in w9x, too.
So, how do i get the base address of a process memory area?
i hope the memory i want to write is not protected, but i'll see.
thx in advance,
raffa

Some ideas off the top of my head: You can use memory mapped files or DDE or pipes or GlobalAlloc with the GMEM_SHARE flag or use Atoms or window messages.
onwards and upwards...

Take a look at this article:

It's c#, but it uses win32 api.

anyone know where I can find some coded audio wave compression algorithms? I'm looking to implement a wave compression program and I've found a couple of algorithms, but I'm trying to find a coded example so that I have something to work from.
It should include Predictor, Rice coding, and Lossless compression.
any suggestions are greatly appreciated. thanks!

Now i have the task to transfer document to PDF. For i should use the Chinese or Japanese font in the PDF, what should i do?
I look up the PDF Reference from Adobe website, but about the font using in the PDF i still do no know very well, especially the Chinese or Japanese font, did everybody know where have the correspoing article or material i could refer to?
Welcome any suggestion!
Thk u for ur help
Good Luck

As a native english speaker I have no idea what you are asking please revise your question. Do you need to create a pdf file from some other format? Are you trying to change the font in an existing PDF file? Do you have a copy of Adobe PDF Writer??

Looks like he wants to find out how to use Chinese/Japanese characters in PDF files, if they are supported, etc.

[EDIT]
I know it is not clearly stated but it will also determine the service pack #. Run winver32.exe to see the result. The test program is in test.cpp.

Call GetVersionEx() and look at the szCSDVersion member of the OSVERSIONINFO struct. It will be set to "Service Pack n"

Hi, everyone!
In a C style project, I think the advantage of a global static function
is its speed. But does it have any limitations? (Thread safety?)
If it does not have any limitations, I will define all of my global functions
and global variables as static.
Can anyone give me some advice of using global static function and global
static variable? Both advantage and limitations.
Thanks in advance,
George

How do you know that?
From what I understand there is no difference in "C" whatsoever between global and static, except for linking.
In "C++" static is a tricky thing because of the order or instantiation etc for the variable. However "good" "C++" should not use global variables, or functions, so static is the only other way to go.

Thanks, AlexO buddy!
What is the difference between a static global function (variable) and
a non-static global function(variable) in your mind?
regards,
George

Terminology, terminology, terminology ...
In C, I have always seen "global" variables created in one of the source files and then all other source files that want access to that global variable use "extern". I have seen some people create those global variables in header files an use tricks with #define and #ifdef, but those end up being just tricks and overly complicate the simple concept that is being implemented.
As for functions, you can write a function and any source file can have access to that function as long as it includes the header file. Okay, go ahead, call these "global" functions.
In C, though, when you use "static" on a function or variable, this is supposed to mean that the function or variable is only visible within that single file.
Therefore, it would be impossible to have a "static global" function or variable, because to be "global" means everything can see it and to be "static" means it is only visible in the file where it is written.
Now, in C++, static functions and variables really belong to the "class" and not to the instantiations of the class. When dealing with "class" variables (as opposed to "member" variables) it also become difficult to think of these being "global." In C++, I have always seen "global" functions and variables to be declared outside of any class.
As for speed, I think this is a moot point, because those declarations affect visibility and access from other code elements and not the final implementation and conversion into executable code. An address of a function must still be known, obtained, and accessed regardless of whether the function is global, static, or something else.
