Hi, I can pull the process image names from taskmanger into delphi but I want to also pull in the description of each file.

                                           images name      username     cpu   memory     description
for example i can pull in:     sonicT.exe      
but i want to pull in:             sonicT.exe                                                         1.1.0

If you check your own process window you will see descripton at the far raght, well I need to pull that into delphi.
This is my code to pull in image names:


procedure TForm1.Button1Click(Sender: TObject);
var
MyHandle: THandle;
Struct: TProcessEntry32;
begin
try
MyHandle:=CreateToolHelp32SnapShot(TH32CS_SNAPPROCESS, 0);
Struct.dwSize:=Sizeof(TProcessEntry32);
if Process32First(MyHandle, Struct) then
ListBox1.Items.Add(Struct.szExeFile);
while Process32Next(MyHandle, Struct) do
ListBox1.Items.Add(Struct.szExeFile);
except on exception do
ShowMessage('Error showing process list');
end
end;

what is this for ?

that's not the description, that's the file version !



function GetFileVersion(const FileName: TFileName): string;
var
  Major, Minor, Release, Build: word;
  size, len: longword;
  handle: THandle;
  buffer: pchar;
  pinfo: ^VS_FIXEDFILEINFO;
begin
    Major := 0;
    Minor := 0;
    Release := 0;
    Build := 0;
    size := GetFileVersionInfoSize(Pointer(FileName), handle);
    if size > 0 then
    begin
      GetMem(buffer, size);
      if GetFileVersionInfo(Pointer(FileName), 0, size, buffer)
      then
        if VerQueryValue(buffer, '\', pointer(pinfo), len) then
        begin
          Major   := HiWord(pinfo.dwFileVersionMS);
          Minor   := LoWord(pinfo.dwFileVersionMS);
          Release := HiWord(pinfo.dwFileVersionLS);
          Build   := LoWord(pinfo.dwFileVersionLS);
        end;
      FreeMem(buffer);
    end;
    result := Format('%d.%d.%d.%d',[Major, Minor, Release, Build]);
end;

uses TLHelp32

procedure TForm1.Button1Click(Sender: TObject);
var
MyHandle: THandle;
Struct: TProcessEntry32;
begin
try
MyHandle:=CreateToolHelp32SnapShot(TH32CS_SNAPPROCESS, 0);
Struct.dwSize:=Sizeof(TProcessEntry32);
if Process32First(MyHandle, Struct) then
ListBox1.Items.Add(Struct.szExeFile);
while Process32Next(MyHandle, Struct) do
ListBox1.Items.Add(Struct.szExeFile);
except on exception do
ShowMessage('Error showing process list');
end
end;



this is the code im using VB, it works tho. Can that code be fitted into this code to see fileversion. ?

Hi SonicM3,

I've made the following code. See if it's what you are looking for.

Regards,
function GetFileDescription(FileName: string): string;
var
  FileVersionInfo: Pointer;
  FileVersionInfoSize: Cardinal;
  handle, FileInformationSize: Cardinal;
  TranslationTable: Pointer;
  FileDescription: PChar;
begin
  try
    FileVersionInfoSize := GetFileVersionInfoSize(PChar(FileName), handle);
 
    if FileVersionInfoSize = 0 then
      RaiseLastOSError;
 
    GetMem(FileVersionInfo, FileVersionInfoSize);
 
    if GetFileVersionInfo(Pchar(FileName), 0, FileVersionInfoSize, FileVersionInfo) then
    begin
       if not VerQueryValue(FileVersionInfo, '\VarFileInfo\Translation', TranslationTable, FileInformationSize) then
         RaiseLastOSError;
 
       if not VerQueryValue(FileVersionInfo,
                            PChar('StringFileInfo\' +
                            Format ('%0.4x%0.4x', [LoWord(PInt(TranslationTable)^),
                                                   HiWord(PInt(TranslationTable)^)]) +
                            '\FileDescription'),
                            Pointer(FileDescription), FileInformationSize) then
         RaiseLastOSError;
 
       Setstring(Result, FileDescription, StrLen(FileDescription));
    end;
  except
    Result := '';
  end;
end;
 
procedure TForm1.Button1Click(Sender: TObject);
var
  ProcessSnapshotHandle, ProcessModuleSnapshotHandle: THandle;
  Struct: TProcessEntry32;
  Module: TModuleEntry32;
  FilePath: String;
begin
  ListBox1.Clear;
  try
    ProcessSnapshotHandle := CreateToolHelp32SnapShot(TH32CS_SNAPPROCESS, 0);
    Struct.dwSize := Sizeof(TProcessEntry32);
 
    if Process32First(ProcessSnapshotHandle, Struct) then
    begin
      if Struct.th32ProcessID <> 0 then
      begin
        ProcessModuleSnapshotHandle := CreateToolHelp32SnapShot(TH32CS_SNAPMODULE, Struct.th32ProcessID);
        FilePath := Struct.szExeFile;
 
        if ProcessModuleSnapshotHandle <> Cardinal(-1) then
        begin
          Module.dwSize := Sizeof(TModuleEntry32);
 
          if Module32First(ProcessModuleSnapshotHandle, Module) then
            FilePath := Module.szExePath;
        end;
 
        ListBox1.Items.Add(String(Struct.szExeFile) + '   ' + GetFileDescription(FilePath));
      end
      else
        ListBox1.Items.Add(Struct.szExeFile);
    end;
 
    while Process32Next(ProcessSnapshotHandle, Struct) do
    begin
      if Struct.th32ProcessID <> 0 then
      begin
        ProcessModuleSnapshotHandle := CreateToolHelp32SnapShot(TH32CS_SNAPMODULE, Struct.th32ProcessID);

            FilePath := Module.szExePath;
        end;
 
        ListBox1.Items.Add(String(Struct.szExeFile) + '   ' + GetFileDescription(FilePath));
      end
      else
        ListBox1.Items.Add(Struct.szExeFile);
    end;
 
  except
    ShowMessage('Error showing process list');
  end;
end;
