winapi - c++ win32 DLL - need to dynamically load a base64 string (very strange!) -

-

First of all, if the title is not really accurate, then I do not know how I would like to have a single sentence in my problem.

The problem I am facing is that I have a Win32 DLL that needs to be dynamically loaded a binary file and do something with it (the binary file is found in the base 64 string, Which DLL then decodes and writes on disk).

Very simple, though in principle, here are the problems:

  1. I tried to put the string in the resources through external program. It works and it appears in resources (according to rehearsed), but when I try to use it from within DLL, it does not work. And yes, I know that you need DLL, which is not from executable file, in which it is included, it does not work either.

  2. I also tried to load the string from any other source (I tried the file, URL and even the registry), but whenever I did it Save in a variable, program crash ("X stopped working" message), I'm assuming that the program that loads DLL did not clean enough RAM to store that extra variable.

and last but at least one additional note: I do not have access to the program's source code DLL (I am writing a plugin more or less), so I Could not even give a parameter.

I really hope someone can get me out of this dilemma.

Edit: Code on request

Method 1: Loading a base 64 string from a resource 

  HMODULE handle = itsamee; // "IMEE" was set in the DLLAN HSRC HRCA = Search Resource (MaxinterSource (IDRGEFEEE), "Basic Files"); // IDR_PEFILE is 300 if (hResa == 0) printf ("FAIL"); // It always prints "FAIL" ...

.rc file: 

  # contains "resource.h" / contains / It defines only IDR_PEFILE and contains & lt; Windows.h & gt; LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_AUS IDR_PEFILE BASICFILE "app.txt"

Method 2: Loading base64 string from the registry 

  HKEY hkey; RegOpenKeyEx (root, key, 0, REG_READ, and hkey); // "root" is "HKEY_CURRENT_USER" and "key" is "software \\ Microsoft \\ windows \\ current version \\ run" DWORD type = REG_EXPAND_SZ; DWORD cbData; RegQueryValueEx (hkey, name, NULL, and type, NULL, and cbData); Char * value = new char [cbData]; RegQueryValueEx (hkey, name, tap, and type, (LPBYT) and value, and CBDTa); // "name" "payfile" is RegCloseKey (hkey); // Now here I had two lines of code before the first one: printf ("ok"); // It will always print "Ok" / this is the second version: printf ("OK, value is% s", value); // It will not print, instead I "X stopped working" error std :: vector & lt; Char & gt; Dec = base64_decode (value); // This is never before, "stopped working", even if

p> The mistake was that (LPBETE) And the value did not make the buffer itself by writing the function to the pointer and it could be changed to the (LPBYTE) value . Thanks for Mark Ryanom for this answer!

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

I am thinking that there is something that I can do better so that my process list should start with the command with MySQL Be clear Currently I am looking for a lot: 17325 user_a localhost db_1 sleep 1132 NULL 17464 user_a localhost db_1 sleep 1124 NULL 17983 user_a localhost db_1 sleep 1078 null 18113 user_a localhost db_1 sleep 1068 NULL 18207 user_a localhost db_1 sleep 1060 NULL 18231 user_a localhost db_1 sleep 1058 NULL 18353 user_a localhost db_1 sleep 1047 NULL 18447 user_a localhost db_1 sleep 1040 null 18489 user_a localhost db_1 sleep 1036 NULL 23408 user_a localhost db_1 sleep 637 NULL Something in my phpscript is that I want to clean it Can i The script looks like: Select the ID from $ q = 'db_1 where fkId = 2'; $ Ar = mysql_query ($ q); ($ Line = mysql_fetch_array ($ qr)) {echo ($ row ['id'];} Thanks in advance! I'm guessing that when you have 10 threads, you're constantly using the connectio...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
