Hi,
I used C to code this.
I though it's not too much different with MASM, right? :biggrin:
In the following PHP' code, I can show image (from my local directory [C:\xampp\htdocs\key.bmp]) into my WebBrowser (Internet Explorer)
echo "<img src='C:\\xampp\\htdocs\\key.bmp'><br>";
I want to do the same thing but with another way.
I wrote the following C' code.
I think I already written it correctly, but the image isn't appear when I open my WebBrowser (Internet Explorer) in localhost:8888
I have a friend who has same problem in here:

Do you think what's wrong with my code?

The best way to send an image to the webbrowser is ATL followed by the MSHTML interfaces.See msdn for that.
Hi ToutEnMasm ,
Yes, I know it.
But what I want to know is: how to do it by socket? :biggrin:
Hi,
I got this work.
I guess it's only one step again.
How to put it on text/html, so I can change content-type in the following code into text/html and it's image also appear like
"<img src='C:\\xampp\\htdocs\\key.bmp'>"
Thank you.
//Reply to client
FILE *f_in; // these are the i/o file handles
unsigned long Size;
f_in = fopen("image.bmp", "rb");
if (!f_in)
{
printf("fopen failed\n");
}
fseek (f_in, 0, SEEK_END);
Size = ftell(f_in);
fseek(f_in,0,SEEK_SET);
char Buffer[Size]; //Buffer = new char[Size];
fread(Buffer, Size, 1, f_in);
char cSize[MAX_PATH];
sprintf(cSize, "%i", Size);
fclose(f_in);
message =

Hi TWell,
I already do that before in my code.
And it's sill show blank image like the attached file
Thank you.
