Gigabyte dll functions

[Razor]

Easy Tune 4 Download
After compiling just drop the project in easy tune 4 directory and voila you have a temperature reading(or something else) program!


This function works 100% TESTED!

Delphi-Quellcode:

function tform1.GetCpuTemp: cardinal;
type
  LX_Get_CPUTempValue = function(pCpuTemp: Pointer): cardinal stdcall;
var
  hInstDll: THandle;
  Get_CPUTempValue: LX_Get_CPUTempValue;
  Pfad: AnsiString;
begin
  Result := 0;
  Pfad := ExtractFilePath(application.ExeName) + 'w83781d.dll';
  if FileExists(Pfad) then
  begin
    hInstDll := LoadLibrary(PChar(Pfad));
    if hInstDll <> 0 then
    try
      Get_CPUTempValue:= GetProcAddress(hInstDll, 'LX_Get_CPUTempValue');
      if Assigned(Get_CPUTempValue)  then
        Get_CPUTempValue(Addr(Result));
    finally
      FreeLibrary(hInstDll);
    end;
  end;
end;

But this dosent work!Please tell me whats wrong?Also if somebody can write about other functions how to call them?
Thanks!

Delphi-Quellcode:

function ismotherboard: boolean;
type
  LX_IsGigaMainBoard = function(pIsGigaMainBoard: Pointer): boolean stdcall;
var
  hInstDll: THandle;
  IsGigaMainBoard: LX_IsGigaMainBoard;
  Pfad: AnsiString;
begin

  Pfad := ExtractFilePath(application.ExeName) + 'w83781d.dll';
  if FileExists(Pfad) then
  begin
    hInstDll := LoadLibrary(PChar(Pfad));
    if hInstDll <> 0 then
    try
      IsGigaMainBoard:= GetProcAddress(hInstDll, 'LX_IsGigaMainBoard');
      if Assigned(IsGigaMainBoard)  then
        IsGigaMainBoard(Addr(Result));
    finally
      FreeLibrary(hInstDll);
    end;
  end;

is it allowed to use the gigabyte dll?

and please specify "this doesnt work".
what do you mean with that?
what error appears?

[Razor]

No error comes up until you dont drop it in easy tune 4 directory.It shows false on gigabyte motherboard.But it must show true becouse the board is gigabyte...

[gsh]

try it so

Delphi-Quellcode:

function ismotherboard: boolean;
type
  LX_IsGigaMainBoard = function(pIsGigaMainBoard: Pointer): boolean stdcall;
var
  hInstDll: THandle;
  IsGigaMainBoard: LX_IsGigaMainBoard;
  Pfad: AnsiString;
begin

  Pfad := ExtractFilePath(application.ExeName) + 'w83781d.dll';
  if FileExists(Pfad) then
  begin
    hInstDll := LoadLibrary(PChar(Pfad));
    if hInstDll <> 0 then
    try
      IsGigaMainBoard:= GetProcAddress(hInstDll, 'LX_IsGigaMainBoard');
      if Assigned(IsGigaMainBoard)  then
      begin
        IsGigaMainBoard(Addr(Result));
      end
      else ShowMessage('Error');
    finally
      FreeLibrary(hInstDll);
    end;
  end;

maybe der is an error while loding the dll

and do you know that this type deklaration is correct?
LX_IsGigaMainBoard = function(pIsGigaMainBoard: Pointer): boolean stdcall;

[Razor]

Yes i think it is correct do we have someone here that has a Gigabyte board to test this?
I need this function as a sort of protect mechanism and it goes like this if you have a gigabyte motherboard then it will show cpu temperature.So if ismotherboard then cputemp...

Hi,
well to me it seems to be much easier if you just explain where you've got the signature from. Is there some SDK/Specification published by Gigabyte?

And if so, I don't think that they will use the Pointer to an Delphi-Boolean as an argument of the function, neither they will use this Type for the return-parameter. Because of Portability the might have used something like an C-Bool (an Integervalue, if 0 = false, true otherwise). But why should this method return the result by an argument and as a result of the function?

Well i got the info from Delphi Praxis

I see. So the signature of LX_Get_CPUTempValue is well known and testet, and hopefully other functions work similar, but this can't be assured by one known signature.
Well, I guess that you should change the boolean in the DLL-Function Call (as parameter and result) to LongBool. This is the more convenient way do return a True or False, because most languages supports a generic Integer Type (int in C, Integer in Delphi, ...), while boolean might be implemented in different ways.

As you can see, he just copy & paste from the working temperature code. He renamed the parameter and that's all. He has no knowledge about the things he does - but he also don't want to know. He only wants it running (and getting the code)...

Nobody knows and now you are deleting my posts?Oh thats nice!
