Hello,
what do I have to change in the code so that I see something on the oled display 0x78?
Maybe someone has a tip for me
Thanks :)

Did you update the screen after calling ssd1306_WriteString?
ssd1306_UpdateScreen();

Well, you have only given us what you consider to be a sufficient part of your programme. For example, have you included the header file with the fonts?
You could also test whether you can fill with black, for example, after filling with white (using a debugger and a breakpoint or some delay in between). You'll probably even be able to see something, as you're currently writing in white on a white background with the programme part mentioned above...
