Hi Marco,

Thanks for the feedback.  I'll look into adding a button (no guarantees though).
I'm in the middle of the next thing though, so it might be a bit for enhancement, as well as now testing the new 14.5

Assembling and linking the code below with Poasm Version 14.50.0 :

Code Select Expand

.386
.model flat,stdcall
option casemap:none

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

ALIAS "OutputText"="printf"

includelib  \PellesC\lib\Win\kernel32.lib
includelib  msvcrt.lib

.data

string      db 'Hello world!',0

.code

start:

    invoke  OutputText,ADDR string

    invoke  ExitProcess,0

END start
The executable is crashing.

An Ollydbg session is demonstrating the issue :

Code Select Expand

012D1000 > $ 68 00202D01    PUSH CalcLen.012D2000                    ;  ASCII "Hello world!"
012D1005   . E8 F6EFFFFF    CALL CalcLen.012D0000
012D100A   . 83C4 04        ADD ESP,4
012D100D   . 6A 00          PUSH 0                                   ; /ExitCode = 0
012D100F   . E8 00000000    CALL <JMP.&KERNEL32.ExitProcess>         ; \ExitProcess
012D1014   $-FF25 5C202D01  JMP DWORD PTR DS:[<&KERNEL32.ExitProcess>;  kernel32.ExitProcess
012D101A   .-FF25 64202D01  JMP DWORD PTR DS:[<&msvcrt.printf>]      ;  msvcrt.printf

CALL CalcLen.012D0000 is not correct.

Hi Pelle,

Thanks for the new release. Regarding the keyword ALIAS :

Revised POASM handling of ALIAS directive (IA32, AMD64, ARM64).

Could you give an example? I am trying to rebuild my example below :

https://forum.pellesc.de/index.php?topic=11168.0

This one does not seem to work with Poasm Version 14.50.0 :

Code Select Expand

printf PROTO C :DWORD,:VARARG
OutputText PROTO C :DWORD,:VARARG

ALIAS "OutputText"="printf"

Setup for X64/X86:

Setup for ARM64:
https://www.pellesc.se/1450/setupa.exe

Changes:

Most changes are of the kind "if not correct, none of the Pelles C tools would build or run", but to verify reported bugs are fixed let's do a Release Candidate...

Hi John,

I'm glad you found my feedback helpful. The issue has been fixed! During my testing, I found that I missed a 'Set current time' button. I think it would be helpful to have a way to reset the start time to the current time, which would be consistent with the "button" that sets the current date. Anyway, this is just a small suggestion.

Assembly discussions / Saving a bitmap from handle

Last post by Vortex - July 11, 2026, 10:54:05 PM

SaveBmpFromHBitmap function creating and saving a bitmap represented by the handle. The example code below loads a bitmap and recreates it with SaveBmpFromHBitmap.

Code Select Expand

.386
.model flat,stdcall
option casemap:none

include     Example.inc

includelib  kernel32.lib
includelib  user32.lib
includelib  gdi32.lib

SaveBmpFromHBitmap PROTO :DWORD,:DWORD

.data

BmpFile     db 'Sample.bmp',0
filename    db 'TestBitmap.bmp',0

.data?

hBitmap     dd ?

.code

start:

    xor     eax,eax
    invoke  LoadImage,eax,ADDR BmpFile,\
            IMAGE_BITMAP,eax,eax,LR_LOADFROMFILE

    test    eax,eax
    jz      @f
    mov     hBitmap,eax

    invoke  SaveBmpFromHBitmap,eax,ADDR filename
@@:
    invoke  DeleteObject,hBitmap
    invoke  ExitProcess,0

END start

Thanks Marco!

I really appreciate you taking the time and providing testing feedback.👍👍👍

From your test I should deselect PowerShell 7 in Choice Dialog and default back to C, I think that will correct the 'selected but disabled situation'.  Great test.

I also added checks in a few other places too just in case you really go wild  , and improved messaging text. 

Nice to think outside the box!  Thanks again.

Version 2.0.1 attached.

John Z

P.S. I was testing PowerShell 7 absence just by renaming pwsh.exe - much easier than uninstall.

Update 7/17 removed attachment to conserve space.  Newer sources 2.0.2 attached further down.

Hi John,

Thank you for this update!

I tested the program on a PC without PowerShell 7 installed. When I click the 'Settings' button, the 'Use PowerShell 7' option is correctly disabled. After closing the program, as a test, I manually opened the 'zcalendar.ini' file and set the 'Method' key to 4. When I reopen the program and then the 'Choose method' dialog box, the 'Use PowerShell 7' option is both disabled and selected. In fact, when I then try to create a task, at the confirmation stage, the program naturally displays the 'Failed CreateProcess' error window with the message

Code Select Expand

"C:\Program Files\PowerShell\7\pwsh.exe" -WindowStyle Hidden -FILE "R:\Temp\calendar_exe\SCR1.PS1"

This is a deliberately unusual test scenario, but I simulated having subsequently uninstalled PowerShell 7 after setting it as the default task creation method in the program.

No biggy - just something to do...

Here is version 2.0 of the simple calendar program.  The calendar program now is also the alert program, meaning no longer is there an Alert.exe used to notify that a scheduled item is due.  Version 2.0 supports four 'Methods' to schedule an alert; VBS, PowerShell 5.1, C, and PowerShell 7.  The 'Method' to use can be selected, but defaults to C if no selection is made.  An ini file has been added to store the 'Method' chosen.

The help file has been updated.

Old sources removed to save space, new version posted on page 2

As the original, it can be run from a USB, just three files, nothing written to the registry, no phone home or telemetry.  Simple calendar with a few 'extras' thrown in...

All sources are in calendar_V2a_sources.ZIP
Just the calendar.exe and the help file calendar.chm are in calendar_v2a_exe.7z
