StartBar Version 1.0

[Biterider]

Hi!
I want to share a fun project I call StartBar. It is intended to replace the "MS-Launch bar" on my box. It uses ObjAsm32 classes and COM interfacing, so it can be seen as an example of how to use these techniques.
Attached is the zipped exe file and at our homepage you can find the full source code. To note is the small exe file size (~67kB)!

Enjoy!  :8)

Great tool  :U to access all the help files i need every day...

I got an error "reading from memory" at following location:

00001420   FF77 14          PUSH DWORD PTR DS:[EDI+14]

but i dont know what i exactly did causing this error, and was not able to reproduce it yet.

[P1]

Getting it to finish, is a chore.

Start with downloading and installing latest OA32INST.ZIP

Added to Make.bat
Set MASM32_PATH=C:\Masm32
Set OA32_PATH=C:\Masm32\ObjAsm32

Missing LEFT_16x16_16.ICO, copied & rename an Exit ICO

GripI.bmp > Grip.bmp

We are up to the assemby errors.  Done for today.  Play some more tomorrow.

Hi Phoenix!
Can you say me under what circumstances you get the GPF? Thanks.

Hi P1!
I updated the download file with the correct files. About the compilation errors I think you haven't replaced the COM_Interfaces.inc file were the new interfaces were defined. The compilation paths you added to the make file should be added to your system on installation. It seems that something went wrong... Please add it manually to your OS. Thanks.

Regards,

Biterider

[P1]

Biterider,

Your updated file fixed everything except the path variables you have in the make file.  But I realize that is a setup preference.

Have you thought about making the bar dockable or at least movable to another anchor location?

Regards,  P1  :8)

[Biterider]

P1!
The current release (1.0) is capable to dock at any location on the right or left side of the primary monitor. To move the bar, press the control key and drag the bar to the location you want it. To select the right or left side, pop up the app menu by right clicking any area not covered by the buttons, i.e. the grip bmp. Select setup and the customization dialog appears.
By right clicking on the buttons, a button menu is popuped. There you can select setup to customize the button link.

As you can see in the header section of the Starbar.inc file, I've reserved some bits to dock the bar at the top or bottom of the screen, but it is not currently implemented... I have left something for the next release...  :8)  If you have more ideas, please let me know!  :thumbu

Biterider

Biterider,

I did look for a Help Menu Item.  They say, It's not done until the paperwork is finsih!

Great Job With the Program!!   :U

Biterider, this GPF didn't happen again. Maybe something else went wrong, i dont know. Great job, i like your program!!!

Regards, Phoenix

[Phoenix]

Biterider,

i've got it. Try the following:

- add a new (blank) item.
- move it to the right
- it appears a popup menu, select setup
- memory read error occurs

Hi Phoenix!
I checked the button creation in the OnCommand method and I found an indexing problem related to the IDM_BTN_NEW command
The correct line should be
   

Code Select Expand

Case IDM_BTN_NEW
      mov ecx, [esi].pToolbar
      mov edi, $invoke(SendMessage, [ecx].Toolbar.hWnd, TB_COMMANDTOINDEX, [esi].dSelBtnCmd, 0)

I uploaded the correct exe at the top post. Please, check if the error has gone... If yes, I'll upload the corrected source code.  :8)

Biterider

Hi Biterider,

i just did a small check, the problem is gone, but the startbar also (!?)... as i'm at office now, i have no time to check more right now. I'll have a look this evenig.

Hi Phoenix!
I uploaded a new version (1.0.1) with 2 improvements:
1. The bar repositions when the screen resolution changes (it responds to the WM_DISPLAYCHANGE message).
2. It stops execution when the IniFile can not be fount at startup.

Regards,

Biterider

Hi Biterider!

Are you shure you did upload the new .exe? I have the same GPF again..

--> Access violation when reading [00000125]

[Biterider]

Hi Phoenix!
New upload on first post.   :U

Hi Biterider,

:U :U :U :U :U :U :U :U :U :U

Perfect... I like this one, it will stay on my desktop.

Just a suggestion:

How about different button sizes? I think a smaller one would look nice, too.

Perhaps you could switch to more than one row if more buttons were added?

Good job, than you for sharing!
