Hello, I'm new in this forum. I'd like to ask you if I can write a messagebox in windows-c. Maybe something like this?
void writemessage(void)
{
char msg[] = "Hello world!";
char title[] = "from POASM";
__asm {
push dword 0 // ok button
push dword title
push dword msg
push dword 0
call MessageBoxA
}
exit (0);
}
Thankx
Hi avcaballero,
Here is how it should go :
#include <windows.h>
#include <stdio.h>
char msg[] = "Hello world!";
char title[] = "from Pelles C";
void WriteMessage(void)
{
__asm{
push 0
push OFFSET title
push OFFSET msg
push 0
call DWORD PTR MessageBox
}
}
int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
WriteMessage();
return 0;
}
Hello. Thank you for your replay, it works fine. What I want now is to call a messagebox from c in an external PoASM module, adding it to the project.
Can I define in PoAsm the function MessageBox external?
POLINK: error: Unresolved external symbol '_MessageBox'.
Thank you
following message:
'polink fatal error(363): must be inside a section'.
This error is not listed in the Pelles C help file or in Goggle searches.
Please can anyone tell me the meaning of this error and what I need to do to resolve it?
Many thanks for your help.
