MessageBox User32.dll, how to add links (Go programming language)
To display a MessageBox with clickable links using the User32.dll in Go programming language, you can make use of the MessageBoxIndirect
function along with the MB_USERICON
flag. Here's an example code snippet to demonstrate this:
gopackage main
import (
"syscall"
"unsafe"
)
const (
MB_USERICON = 0x00000080
)
type MSGBOXPARAMS struct {
cbSize uint32
hwndOwner uintptr
hInstance uintptr
lpszText *uint16
lpszCaption *uint16
dwStyle uint32
lpszIcon *uint16
dwContextHelpId uintptr
lpfnMsgBoxCallback uintptr
dwLanguageId uint32
}
var (
user32 = syscall.NewLazyDLL("user32.dll")
messageBoxIndirect = user32.NewProc("MessageBoxIndirectW")
)
func main() {
text := "Welcome to my application!\n\nClick [here](https://example.com) to visit the website."
caption := "MessageBox with Links"
style := uint32(MB_USERICON)
params := MSGBOXPARAMS{
cbSize: uint32(unsafe.Sizeof(MSGBOXPARAMS{})),
lpszText: syscall.StringToUTF16Ptr(text),
lpszCaption: syscall.StringToUTF16Ptr(caption),
dwStyle: style,
}
messageBoxIndirect.Call(uintptr(unsafe.Pointer(¶ms)))
}
In the example above, the text
variable contains the message text with a clickable link specified using Markdown syntax. The caption
variable specifies the caption of the MessageBox. The style
variable is set to MB_USERICON
to display a custom user icon.
Make sure to replace the link in the text
variable with the appropriate URL you want to display as a clickable link.
Note: The MessageBoxIndirect function is a Windows-specific API, so this code will work only on Windows systems. Additionally, you'll need to have Go properly set up on your system to compile and run the code.
Please keep in mind that using MessageBoxIndirect
with clickable links might not be the most robust solution for displaying complex UI elements. If you require more advanced UI functionality, consider using a dedicated GUI framework for Go, such as fyne
, walk
, or gotk3
.
