Assembly discussions / String with random characters

Simple random character generator using cryptographic functions.

Code: [Select]

.386
.model flat,stdcall
option casemap:none

include RandString.inc

.data?

buffer      db 64 dup(?)

.code

start:

    call    main
    invoke  ExitProcess,0

main PROC uses esi edi ebx

LOCAL counter:DWORD

    invoke  RandomBytes,64,ADDR buffer

    mov     esi,OFFSET buffer
    mov     edi,26
    mov     counter,64
    mov     ebx,1
@@:
    movzx   eax,BYTE PTR [esi]
    xor     edx,edx

For external exe, use WinAPI FindWindow()

Hi anatolewilson,

Welcome to the forum!

To do what you are thinking you can invoke a COM object/method to open a web interface from within your program.

I think the attached webbrowser project will get you started.  I am not the author and I am embarrassed to say I don't recall where I originally found it.  Possibly here: http://www.johnfindlay.plus.com/pellesc/ but I'm not sure.

Unzip it and run BrowseApp.exe.   If it looks workable to you dive into the code by opening the Pelles C BrowseApp.ppj file, and modify to your hearts content. 

Hope it helps.

Beginner questions / Run Google Earth

« Last post by anatolewilson on July 02, 2024, 04:32:10 AM »

I have a window into which I would like to run Google Earth.
With CreateProcess Google Earth runs but outside my program.
How could I do?
I thought searching for the window hadle of Google Earth and setting it has a child window of my program.
Is it a solution?

Another version :

Code: [Select]

.686
.model flat,stdcall
option casemap:none

ExitProcess PROTO :DWORD
printf PROTO C :DWORD,:VARARG

includelib  \PellesC\lib\Win\kernel32.lib

includelib  msvcrt.lib

.data

mystr       db '    This    Is   A       Test String.',0
message     db 'Trimmed string = %s',13,10
            db 'Length of the string = %u',0

.data?

buffer      db 64 dup(?)

.code

RemoveSpaces PROC str1:DWORD,buff:DWORD

    mov     ecx,str1
    mov     edx,buff
@@:
    movzx   eax,BYTE PTR [ecx]
    mov     BYTE PTR [edx],al

finish:

RemoveSpaces ENDP

start:

    invoke  RemoveSpaces,ADDR mystr,ADDR buffer
    invoke  printf,ADDR message,ADDR buffer,eax

Beginner questions / Re: Question about sqlite max AND min

« Last post by John Z on June 21, 2024, 11:05:24 AM »

Hi timharvey,

I'm no expert but I reached out to a heavy user who said:

"For the Guy if he has a large number of records he must do two queries, one for max and one for min each one must be into a transaction"

Hope this helps.  This site does have SQL users but of course it is mainly about C and some assembly.

General discussion / Re: Who pays and how much to use Pelles C?

Hi WiiLF23,

Congratulations on achieving your goal, hope it is a winner for you.
Share where it is advertised?

AFAIK Pelle has stopped accepting donations. 

I think you have moved to the dark-side though with 'subscriptions'   
IMO for individuals minor upgrades should be free, and a modest charge made for a major upgrade.

Not related to your software situation but as an individual I will never use software that I must pay every month to use or lose it.  (MS 365 - no thanks!)

Business using it on the other hand might be another story though since they have for a long time been licensing often on a yearly basis.

I will also be making a donation, as Pelles C has made our file sharing software easily possible for which we allow subscription-based upgrades within the application. Very thankful.

Even more tricky (sophisticated?)  One must realize that 9 xor 32 is 41 

neat!
