Thread: [Dev-C++] More Version checking

thanks Derek for the reply. I imagined it would probably have something =
to do with the registry, but i checked through everything in the =
regedit.exe program but acrobat reader doesn't seem to have a version =
value. Can you or anybody else  think of another technic? And do you =
know how to get values from the registry

thanks for you time everyone
tim

    I don't have first-hand experience with using any library that =
provides for Windows registry manipulation... but I do have Acrobat =
Reader installed on my hard drive, and immediately found the registry =
key:

\\HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Acrobat Reader

Cheers,
Steve

Hi !

Here is a sample code for version checking:

#include <stdio.h>
#include <windows.h>
#include <winreg.h>
#define BufferSize 255

void NoAR()
{
     printf("Acrobat Reader is not installed\n");
     exit();
}

int main(int argc, char *argv[])
{
  PHKEY hKey, hKeyAdobe,hKeyAcrobatR;
  LONG Result;
  WORD iSubKey=0;
  char Buffer[BufferSize];
  /* check for the key "software" */
  Result=RegOpenKeyEx(HKEY_LOCAL_MACHINE,"software",0,KEY_READ,&hKey);
  /* all right then look for the "Adobe" subkey */
  if (Result==ERROR_SUCCESS)
  {
   Result=RegOpenKeyEx(hKey,"Adobe",0,KEY_READ,&hKeyAdobe);
   if (Result!=ERROR_SUCCESS) NoAR();
   Result=RegOpenKeyEx(hKeyAdobe,"Acrobat Reader",0,KEY_READ,&hKeyAcrobatR);
   if (Result!=ERROR_SUCCESS) NoAR();
   /*print all the subkeys */
   while(Result!=ERROR_NO_MORE_ITEMS)
   {
     Result=RegEnumKey(hKeyAcrobatR,iSubKey, Buffer, BufferSize);
     printf("%s\n", Buffer);
     iSubKey++;
   };
  }
  else printf("No Software key\n");
  return 0;
}

Thank you very much for all your help on version checking. Specially Steve
Perkins and Bruno Berteau
Cheers Folks

Hi all,

I'm trying learn how to access the registry. I saw a document with a fast
explanation that work for win9x and NT. But don't give examples. What i need
to access the registry ?? example to read keys, list keys, subkeys, create
keys, delete keys, ... ??

Can somebody give me a example ??

I need use dll of windows ? API ?? How to use it in dev-c++ ?

Hello Tim,

I tryed ... it!! and have some explanations/examples! Then i tryed it in my
dev-c++ and...! look:

This structure of program work very well. compiled!

#include <stdio.h>

int main()
{

 return(0);
}

But if i try put the code prom open a key in registry....

#include <stdio.h>
#include <Winreg.h>   //Header: Declared in Winreg.h; include Windows.h.
#include <Windows.h>  // i put this 2 headers as is needed in the text.

int main()
{
 LONG RegCreateKeyEx(
 HKEY HKEY_USERS\wendel_test
 return(0);
}

When i try compile i recive:

You can't use #include <Winreg.h> with Dev-C++. Just delete that line. For the use of RegCreateKeyEx, at the link in the beginning of this message, you will find links to some examples.

Hi,

I want to flush (delete) a string value from registry.

I tryed to set it to 0 of this mode:

#include <windows.h>

    int main(int argc, char *argv[])
    {
      HKEY hKey;
      DWORD dwDisposition;
      unsigned char *szBuf = (unsigned char *)strdup("0");

      if (RegSetValueEx(HKEY_CURRENT_USER,
"\\Software\\Microsoft\\Security\\say\\", 0, REG_SZ, szBuf,
strlen((char*)szBuf)) != ERROR_SUCCESS)
        return 1;

      RegCloseKey(hKey);

      return 0;
    }

But it didn't set the value of:
\\HKEY_CURRENT_USER\\Software\\Microsoft\\Security\\say to "0". It crate a
key \\Software\\Microsoft\\Security\\say in \\HKEY_CURRENT_USER . :P

How to do to is set this value ??

And how to for example delete a key \\Software\\Microsoft\\Security\\say\\
??

Can someone gave examples ?? :)

Thkz and Best Regards.

Hello,

You only have to include windows.h before winreg.h.

#include <stdio.h>
#include <windows.h>
#include <winreg.h>

Hi,

I have and use DEV-C++ with last snap-shot.

But i tryed compile this program in .C that i recive and i recived this
errors:

When i tryed compile it here with Dev-c++ compiler it return me the errors:

17 c:\mf\release\reghide.c
c:\mf\release\reghide.h:9: redefinition of `ULONG'

29 f:\dev-c_~1\include\winnt.h
 `ULONG' previously declared here

10 c:\mf\release\reghide.h
 redefinition of `USHORT'

28 f:\dev-c_~1\include\winnt.h
 `USHORT' previously declared here


But, who sent me ... spoken that it compile very well in Visual C++ 6.0!!
Why ???

VC++ 6.0 have some support best that Dev-C++ ?? Or is more complete ??

The opposite happens. Dev-C++'s MINGW compiler is more ANSI compliant
than VC++ (which is 4 years old). Send us the code so as to understand
what is wrong.

Hi,

I'm with a stupid problem! ;)

When i open the Dev-C++ in my Win2k, i create a new project or open a
project it show me the error:

Could not create Code Cinoketion list file

What is it ?? How to fix ?? Why it happends??

Hello again,

The line ' HKEY HKEY_USERS\wendel_test ' is wrong. You can't do that. HKEY is a
registry key handle not the key's name.

Bruno Berteau

Hello Guy,

I recived 4 messages ... and the answers are very different .... answers:

2) > The line ' HKEY HKEY_USERS\wendel_test ' is wrong. You can't do that.
HKEY is a
> registry key handle not the key's name.

3) You can't use #include <Winreg.h> with Dev-C++. Just delete that line.
For the use of RegCreateKeyEx, at the link in the beginning of this message,
you will find links to some examples.

4) It work very well here.

Then i try do the changes in my program ... the nunbem of erros is low ...
but don't work yet ... :-/
In the second case, spoken that handle isn't the key name. But i translate
to my lenguague and handle is a work that don't do sense for me, unhappyly!
:-/
What is the handle ?? Can you show me a correct value that must i use to i
work, in the contrary of the ' HKEY HKEY_USERS\wendel_test '  ??

In the first case, it is a good help for me ... my errors down only for two
erros:

#include <stdio.h>
#include <windows.h>   //Header: Declared in Winreg.h; include Windows.h.
#include <winreg.h>  // i put this 2 headers as is needed in the text.

int main()
{
 LONG RegCreateKeyEx(
 HKEY HKEY_USERS\wendel_test
 return(0);
}

8 f:\dev-c_~1\untitl~1.cpp
 parse error before `0x80000003'

8 f:\dev-c_~1\untitl~1.cpp
 stray '\' in program

What is the error stray '\' in program ?? is it when i used "return(0);" ??
Why ?

In the trirth case, i comment the line "#include <winreg.h>" and it up 4
errors and don't show me a link to examples.

And in the 4 case, it don't work here!! hehehe =]

ps.: Thkz again for all help.

[ ]'s

Best Regards.

This is an example for set key in registry:

    #include <windows.h>

    int main(int argc, char *argv[])
    {
      HKEY hKey;
      DWORD dwDisposition;
      unsigned char *szBuf = (unsigned char *)strdup("lorenzo");

      if (RegCreateKeyEx(HKEY_CURRENT_USER, "test", 0, "REG_SZ",
REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, 0, &hKey, &dwDisposition) !=
ERROR_SUCCESS)
    return 1;

      if (RegSetValueEx(hKey, "string", 0, REG_SZ, szBuf,
strlen((char*)szBuf)) != ERROR_SUCCESS)
        return 1;

      RegCloseKey(hKey);

      return 0;
    }

This program open or create if not exist the key "test" in key
HKEY_CURRENT_USER and create string value "string" with value "lorenzo".



This is an example for get key in registry:

    #include <windows.h>

    int main(int argc, char *argv[])
    {
      HKEY hKey;
      DWORD dwType;
      DWORD dwLen;
      unsigned char szBuf[255] = {0};

      if (RegOpenKeyEx(HKEY_CURRENT_USER, "test", 0, KEY_ALL_ACCESS, &hKey)
!= ERROR_SUCCESS)
        return 1;

      if (RegQueryValueEx(hKey, "string", 0, &dwType, szBuf, &dwLen) !=
ERROR_SUCCESS)
        return 1;

      RegCloseKey(hKey);

      return 0;
    }

This program open the existing key "test" and read value from string value
"string", copy it into szBuf, the size of string is stored into dwLen and
the type of value key is stored into dwType.

I hope this can help you.

Hi,

I'm trying to use the system() function in dev-c++ ... but it don't work
....

I was trying of this mode:

#include <stdio.h>
#include <conio.h>

int main()
{
 char var[15];

 printf("\nType the environment that u want see the value: ");
 scanf("%s",&var);

 system("echo %s",var);

 return(0);
}

Then when i try compile this program i get the error:

16 f:\dev-c_~1\untitl~1.cpp
 implicit declaration of function `int system(...)'


Why ?? The system() is a function of stdio.h ?? why it don't work ... please
show me the correct mode ... if i'm making something wrong ...

thkz

Cheers

[ ]'s

First: when you need the function "system" you should include <stdlib.h>. 
then the prototype of "system" says:

int system(const char *s);

this means that you are allowed to pass only one string to "system", in 
other words: "system" resembles "puts" and not "printf".

Try the following:

---
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX_BUF 50 /* "echo " and var will surely fit in it */
int main()
{
    char var[15];
    char buf[MAX_BUF];


    printf("\nType the environment that u want see the value: ");
    scanf("%s",&var);
    strcpy(buf, "echo ");
    strcat(buf, var);

    system(buf);

  return(0);
}

system() is a function of stdlib.h
