Creating an API for a windows application

mmathys — Fri, 04 Jul 2008 12:28:49 GMT

I am writing a windows application using VB.NET 2005 and I would like to create an API for it, however, I have no clue on where or how to get started. I tried adding a ProgId to my windows form, but when I would try to use CreateObject or GetObject to get a reference to the application, I would receive an error saying "could not create ActiveX object". If anyone has any advice or information to share, I would greatly appreciate it.

Thanks!

Dual Monitor API or Pen Tablet API?

Lucha — Wed, 25 Jul 2007 06:08:54 GMT

Hi everyone!

I'm making a program in Visual Basic 6 that uses this:

1º - I have extended desktop, I mean, my desktop width is two monitors. My graphic card

supports clone mode, I mean, the second monitor copies the first monitor exactly.
2º - I have a Pen Tablet. I have set it up to work with the second monitor. I can change with

the tablet's configuration program, making the tablet work with the first monitor.

The questions are:

a) How can I switch between "extended desktop" and "clone mode" with the program I have made

in Visual Basic 6?
b) How can I make the tablet work with the monitor 1 or the monitor 2 with my program?

If it's needed to program this as subprograms in other language like C, C++, C#, vb.net, etc,

I will do it for sure.

Thank all of you for all your answers and your time.

My idea is to control IE instance by software

eugene2005 — Wed, 13 Jun 2007 22:18:52 GMT

My idea is to control IE instance by software
I want to solve my problems in two ways

First one is by controlling IE by mouse_event with cursorpos but not with sendmesage or postmessage API.
I want to invisibly control IE instance and click on it where I want to by sending mouse_event, but without user notice, is there any chance?

Is it possible to control IE for example in background while PC is idle and screensaver works?
Or perhaps when PC is idle detect it and show JPEG screenshot and work with mouse_event on background, so to call behind the scene?
Or perhaps in parallel user mode FAST USER SWITCH terminal service?

I don’t want to click by parsing html code body.outerhtml, tagname ("A").click
Any suggestions or any ideas with technical details?

getting text from another program

bwarn70 — Sat, 02 Sep 2006 11:02:36 GMT

I am coding in vb2005... I am trying to create an interface between two programs (an accounting program & an imaging program). What I want to happen... select item (text) in accounting program and then by pressing a hotkey, pass the text to the imaging program to run a search. I started out trying to use sendmessage api and found that in VB i was having problems due to not being able to create pointers for the call. I am now thinking that the best way to get the text from the accounting program may be through the Microsoft Active Accessibility but am having trouble finding any documentation on how to use it. And maybe this isn't the best approach either. Any help and input would be greatly appreciated.

Tasks:
1 - hotkey creation & responce - DONE
2 - Get selected text from syslistview in accounting software
2a - Get hWnd for syslistview - DONE
2b - Get index of selected item - DONE
2c - Get text of selected item - PROBLEM
3 - Pass text into imaging software to run search - DONE

SAPI 4, Direct Speech and foreign language

Zion — Mon, 19 Feb 2007 18:47:01 GMT

Hi folks,

I've downloaded the KAREN and HANS voices from the Microsoft agent website, which is the Dutch Lernout & Haspie TTS3000 engine. I've found some code to list the available engines in a combobox, but this only lists the default MS engines. This, due to the fact that these voices are Sapi 5 complient. The voices I would like to use are only Sapi 4. Is there a way to use this engine as default on form load or something? I'm writing a program in dutch, which helps children with homework. I would like the displayed words to be read out load as well.

Now, i've played with the languageid, but can't seem to find the right ID on the net for it or my syntax is totally wrong.

Any help would be greatly appreciated.

Controlling 'Scrolled' Location of Clicked Item from ImageCombo box List

Matt — Fri, 06 Oct 2006 14:19:48 GMT

This is the big picture, I am currently working with an imagecombo
By default, when I click on an image associated with a comboitem
in its dropped down list, the combobox scrolls up.

I want to modify this behaviour so that while I am clicking on an image,
it wont scroll up, and that it should scroll up only when I click on
the textbox portion of the combobox item from its scrolled down list or
anywhere outside the dropdown list portion part of the same combobox.

The workaround I did was to allow the default scroll up behaviour onclick
(scrollup) and then immediately make it drop down again at the exact
scrolling position where it was before the click (so that user dont lose
orientation) where he was before the click.

But it is not happening fast enough and the flicker (due to scroll up then
forced scroll down) is very noticeable about say 1/4 of a second.

There are four images alongside the text portion of each comboitem and
each of these images serve as on/off toggle for various features of the
application.

All suggestions welcome and thanks so much for all the help you can give.

Gratefully,
Matt

Router Auto Configuration Wizard

dogangoko — Fri, 07 Jul 2006 03:55:16 GMT

Hi,

I've been researching about router configuration ( auto configuration wizard ) by Visual Basic. I've found out a software which actually does this. But as i'm not experienced in Visual Basic i couldn't figure out. The sample is here : http://www.turktelekom.com.tr/ModemAkredite/inca_kurulum_programi.zip

I'd like to do the same application for my router which is a dlink dsl-524t. Does this program use SNMP, telnet or which way ? How can i save the config to the router by visual basic ?

Modify date in DateTimePicker via SendMessage

Sweetve13 — Fri, 07 Jul 2006 10:57:14 GMT

I am wanting to get and change the display date in the datetimepicker control located in a 3rd party application that runs in the background and thus not in focus. I found that DTM_GetSystemTime and DTM_SetSystemTime can do this but I have been unable to get it to work. I get an error message stating:

"A call to PInvoke function 'DateTimePicker!DateTimePicker.Form1::SendMessage' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature."

I've noticed that changing the "Byval lParam As SYSTEMTIME" to "ByRef lParam As SYSTEMTIME" in the Sendmessage declare will remove this message BUT it still does not make any changes! Any suggestions? Thanks.

Sending hotkeys via SendMessage

Sweetve13 — Thu, 25 May 2006 10:19:50 GMT

I'm using sendmessage in vb.net to send keystrokes to another application that is not active (application runs in background thus not active). This part works just great. But I am not able to send hotkeys. Say for example. I'm sending keystrokes to notepad and I want the date. One can do this by clicking Edit>Time/Date or sending Alt then E then D. How could I achieve this? Thanks!

p.s. I've tried using WM_KEYDOWN, WM_KEYUP, WM_COMMAND to no avail. I'm sent the commands both to the handle for the specific control and the application itself (hwnd and x) and still no success.

This is what I'm using to send the keys so far (sending keys works, just not hotkeys):

Code:

VB.net:

Private Declare Ansi Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As Integer, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As String) As Integer

Application instances

toni — Fri, 02 Jun 2006 10:37:46 GMT

Hello,

May I can get some help here... I'm trying to properly detect if more than one application instances are started.

There is App.PrevInstance, but this ensures only a previously started instance, I also need a subsequently started instance.

There is also the API function FindWindow, but this detects even the calling instance itself. I need here only if there is another instance started.

Any other suggestions?

Thanks.
