Create A System-wide Independent Universal Counter Object Primarily For Database Keys?
Apr 5, 2010I would like to create/use a system-wide independent universal 'counter object' that can be called via COM in a thread-safe manner. The counter object will be passed an ID to identify which counter to return, handle the counting, 'persist' the count (occasionally), have reasonable performance (as fast as possible) perhaps capable of 1000 counts per second or better (1mS) and be accessible cross-process/out-of-process. The current count status must be persisted between object restarts/shutdowns.
The counter object is liklely to be a 'singleton' type object implemented in some form of free-threaded dictionary, containing maybe 10 counters (perhaps 50 max). The count needs to be monotonic and consistent, (ie: guaranteed unique sequential values).Each counter should have a few methods, like reset, inc, dec, set, clear, remove. As a luxury, I would like to have a variable-increment (ie: 'step by' value). To support thread-safefty, perhaps some sorm of critical-section or mutex call. It just needs to return a long/4byte signed integer.
I really want something that can be called from anywhere, including VBScript, so I figure COM is my preferred solution.The primary use of this is for database keys. I am unable to use autoinc or guid type keys and have ruled out database-generated counting systems at this point.I've spent days researching this and I have really struggled to find a solution. The best I can find is a free-threaded dictionary object that can be instantiated using COM+ from Motobit - it seems to offer all the 'basics' and I guess I could create some form of wrapper for this.

Sep 9, 2010how can i capture system wide selectedtext?
i've managed so far to get a global mousehook + i'm hoping to capture the selectedtext from anywhere system wide when the user left clicks.
i tried using the keybd_event api to send CTRL+C to copy any selectedtext to the clipboard but it has unexpected effects + seems to run before the text i've just selected becomes selected.
here's the code i'm using:

Get System Wide KeyUp Event?
Jul 15, 2011Currently I am able to see if a key is currently pressed via the GetAsyncKeyState function. Currently I just simply have a timer running in the background that constantly checks if a certain key is pressed in order to run a command. However my issue is if the user holds down the key it will continually run that bit of code over and over per timer tick. Is there a way or another function to detect a keyup or keypress only. This is my current code to detect keys:
Public Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Windows.Forms.Keys) As Integer Public ReadOnly Property CurrKey(ByVal key As Windows.Forms.Keys) As Boolean
Get Return CBool(GetAsyncKeyState(key))
End Get
End Property

VS 2010 - Wide Search -program Allows Users To Insert Documents Along With A Bunch Of Their Attributes Into The Program
Apr 14, 2011The program allows users to insert Documents along with a bunch of their attributes into the program. The documents are stored in a relational database. One of the required functionalities is allowing the user to look for such documents. The User normally search directly for the obvious attributes of the document, like a unique ID, or it's Title. The problem is that from the search parameters is not allways known which ones will the user fill. For example the user inserts the name and version of the deocument, another time the user enters part of the Title and the person that delivered the document, or might just enter the document number and nothing else. Some of the data might even be incomplete, like title, name of the person who created the document and so on. The idea from the person who designed the system (I'm only reimplementing it) was to allow easier searches for the user, and allowing the user to search for more parameters tod with the idea that "the more parameters, the more specific results", since the results are always group of documents instead of single documents.

How To Implement A System Wide Text Replacement In Windows Programmatically
Dec 20, 2010I have a small VB .Net application that, among other things, attempts to substitute system wide typed text by the user(hotstrings concept). To achieve that, I have deployed 'ahk2exe' and 'AutoHotkeySC.bin' with my application and did the following:When a user assignes a new 'hotstring':
Kill 'hotstring' exe script file if running Append new hotstring to the script file (if non exist then create a new one)Convert edited/new script file to exe (using ahk2exe)Run the newly converted script exe(somewhere there I also check if the hotstring has been already assigned)However, I am not totally satisfied with this method for the following two main reasons:
The extra resources deployed with the application. Lag: The time it takes for the system to kill the process and then restart it takes a minimum of 5 seconds on my fast computer and more on other computers. That amount of time is much more than the time it takes the user to assign the hotstring, minimize/close the window and then test his/her new hotstring. When the user does so initially with no success they will think the process failed. So this method is not very good for user experience.I am looking for a different method or implementation. May be using keyboard hooks? Or maybe adding a .dll library that achieves the same. Are there any resources you know about that might help (free or commercial)? What is the best way to achieve my desired goal?

May 25, 2009I have been trying over the past few days to make a program sit open on the computer, waiting for a key press (which will be the hotkey). When the key is pressed, it will execute a peice of code and minimize itself. Im really sorry if this is too simple but im stumped over this one. I have searched google alot but no luck
So: I need to know how I can have the program 'monitoring' or 'looking for' a certain key press while it is doing something to tell it to stop, bearing in mind when the program actually starts it will minimise and stay minimised untill this hotkey is pressed that makes it maximise itself and stop the program.

View 2 RepliesVS 2005 - Create A "post Office" Program That Will Send Html Emails Thru The System.net.mail Framework
Oct 19, 2009I am a one man dev shop and need some outside opinions on how to approach this project.
I need to create a "post office" program that will send html emails thru the system.net.mail framework.
For each job submitted to the postoffice the app would need to read a user created html email string from the database, read a string of email addresses to send to and send out the emails based on a set processing time.
The first step would be to parse out the email addresses to find out how many emails it needs to send out and determine how many it would need to send per minute to complete the job in 20 minutes tops. I.e. if 1000 email addresses are submitted per job it would determine that it needs to send 50 emails per minute to complete the job.
The part I am stuck on is how I should queue the emails. If the app determines it needs to send 50 a minute should I only load up the first 50 on a timer event then get the next 50 queued up for the next timer tick? Or would it be better to load up all 1000 in a loop and build in some kind of wait time after it sends the first 50?
