[Dev-C++] [C/C++][Windows XP][GUI] CreateWindowEx()/CreateWindow() does not create buttons with "XP look-and-feel".

[Frederico Marques]

Hello people.

I am currently developing a application that should simulate NeoSoft, InstallShield, and similar installers. I am aware that such packages are available from the Web, however I desire to gain knowledge about such applications.
At the moment, I have a problem when I try to create buttons. The buttons created are Win98 like, gray, with no 3d-effect. I tried chaging the button stryles, in the dwStyle argument, and also messing around with dwExStyle, with no success.

Below follows a snippet with relevant code only ( for readability purposes. )
/** C code. { */
/** Please assume hwnd as a created window. The following code is triggered it WM_CREATE. */

HANDLE hButtonOk = NULL ;

if ( ( hButtonOk = CreateWindowEx( WS_EX_LEFT | WS_EX_TOPMOST, "BUTTON", "Seguinte", WS_CHILD | WS_VISIBLE | BS_TEXT | BS_PUSHBUTTON, // Styles.
250, 330, 100, 25, hwnd, (HMENU)0, hThis, NULL )) == NULL ) {
MessageBoxA( hwnd, "Erro Irrecuperável", "Ocorreu um erro irrecuperável a criar um elemento de Gui : hButtonOK", MB_ICONERROR|MB_OK);
SendMessageA( hwnd, WM_QUIT, 0, 0 );
return -1;
}


/** }*/


Please let me know if something is unclear, and of course, if you know the sollution :)
Thanks every1 ;D

In Order to use WinXP visual styles for your controls, you should do the following:

Create a XML manifest file called <programfilemane>.manifest (for example: installer.exe.manifest) and place it in the same folder of your program executable file:

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
version="1.0.0.0"
processorArchitecture="X86"
name="CompanyName.ProductName.YourApp"
type="win32"
/>
<description>Your application description here.</description>
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
processorArchitecture="X86"
publicKeyToken="6595b64144ccf1df"
language="*"
/>
</dependentAssembly>
</dependency>
</assembly>

Then link comctl32.dll library into your program (in MinGW, for example, add -lcomctl32 to the linker command line), and include commctrl.h header file.

In the program source, call InitControlsEx function as follows:


INITCOMMONCONTROLSEX iccs;
iccs.dwSize=sizeof(INITCOMMONCONTROLSEX);
iccs.dwICC=ICC_STANDARD_CLASSES; /*See MSDN Library links below for further options */
InitControlsEx(&iccs);
