C# - Keyboard Messages Windows Flow - Catching The WM_KEYDOWN Message Through WndProc
Sep 16, 2009I'm developing a program where I've had to add a keyboard shortcuts system. The problem is it uses a third party OCX for a part of its display, and it is catching some essential WM_KEYDOWN messages when in focus, like Ctrl+C, Ctrl+V, etc. I've tried catching the WM_KEYDOWN message through WndProc, but the message is not propagating, so I guess the keyboard messages go from the inner container to the outer one, don't they?
The WM_KEYUP messages can be caught tho, but I'd prefer to be able to catch some of those messages on the KeyDown event. I'm aware I could make some low-level hook, but I'd like to avoid this workaround. Well, if the WM_KEYDOWN message goes from the OCX to its top level container, I guess I'll have to treat those key combinations in the KeyUp event.
VS 2008 Catching If Windows Has Been Locked Then Unlocked?
Aug 23, 2009My application i am using on another computer (Windows Vista) has got a screenshot code inside a timer of 10 seconds. It works perfectly until the user Locks Windows.
When the user locks windows or switches user then the application throws a hissy fit and errors because it cannot take screenshot pictures.

This way i can have a timer of 1 second and if the computer has been locked then the timer for the screenshots can been stopped , and then when the user logs back in the timer can restart.

Nov 4, 2010I've been whining for several months about the way Windows 7 prevents application exceptions from actually occurring, and arbitrarily assigns "compatibility settings" without actually detailing what those settings are, even during Visual Studio Debugging operations. Am I just completely ignorant to some setting I can toggle to turn all that garbage off and make Win7 act like an operating system that wasn't designed for a 2 year old? It never hurts to try. In a worst case scenario,

.Net Windows Service Console Messages?
Sep 22, 2011I have a .Net Console application which displays thousands of lines on the console each minute. I want to convert it to a Windows Service, however I still need a way of viewing these messages. There are far too many messages to write them to the event log or even a standard log file. I was wondering if there were a way to write a systray app that could simply intercept these messages from the service and display them in a console window. I have no need to save older messages, I only need to see current activity.

Apr 1, 2010I'm not even sure if that's what I want.But, here's my question. I have written a small program to automate the running of some files. These files have the potential to give an error in the form of a MessageBox which will halt the whole process. Is there a way to detect if that window pops up so that I can kill the process so the next file can run.
Also, if I can get the location of this MessageBox, is it possible to get text out of it so that maybe I can email myself the error so that the processes can keep running but I cango to that file and fix it.
Capturing Windows Messages In A Console Application?
Oct 27, 2009I have a console application where I successfully have added custom menu item in the application's system menu using the Windows API calls. How do I hook into the events to capture the event raised when the user clicks on one of these menus? All my Google results talks about overriding the WndProc method, but this doesn't exist in a console application.

Jun 5, 2009This may seem complicated but it's a somewhat basic concept, just probably a complicated execution, I am trying to create a program that will allow you to basically "IM" between computers on a LAN network. That's the concept, I plan on doing this by generating .bat files, executing them and printing the last few messages sent in a label, the big problem I have is receiving messages, I have no idea whatsoever how to even go about finding out how to take the messages received from the messenger service and print them into the label, any ideas?EDIT: This is in VB.Net 2008

VS 2008 Error Catching With Registry Settings
Nov 4, 2009I'm editing some settings in the registry and then adding items to a ListView.
[Code]...
If I'm not mistaken, the code will not continue in the Try block if the first part fails and then move on to the catch statement, correct? I'm adding and deleting a bunch of different entries in the registry and the computers I've tried my app on so far, have not failed. So I'm not able to test if this method will work for error catching. If there's a better method, I'd appreciate the info.

View 3 RepliesDeveloping Messaging Framework For Windows Application That Sends Messages To Java Application
Feb 9, 2009I am in the process of developing a messaging framework for a windows application that sends messages to a java application. To be precise when the win app wants to send a message it simply drops the message in a common database table which will be picked up by the java app. The windows application is deployed across 10 application servers (10 instances) over citrix for load balancing.Each instance of the application is capable of sending a message to the java application and each of these messages should have a unique id. From my end I need to make sure every message generated has to carry a unique id so that they can be identified when necessary. All the messages can be cleared every day or two.i am not quite sure about a best method of achieving this. Initially I wanted to create a static method that serves the next available id (incrementing the last id by 1). But this approach willn't guarantee unique number as the application starts only when at least one user is logged on. For e.g .On one server the app starts when a user logs in, he then sends a message and then the application stops when that user logs off. So when a next request for the app comes to that server a new instance will be started.

View 3 RepliesVS 2008 Many Messages Sent To Server - Few Processed?
Jan 20, 2010I'm using a modified version of John's Message server, instead of passing a string I am passing a serializable object called "DataClass".This is my modified Read sub to process data that gets sent from the client to the server:
vb.net
Protected Overrides Sub Read(ByVal ar As IAsyncResult)
Dim asyncState = DirectCast(ar.AsyncState, ReadAsyncState)
Dim buffer = asyncState.Buffer
Dim client = asyncState.Client
Dim host = Me.clients(client)
[Code]...
The message is received fine when they aren't in quick succession, however I tested it by sending like 1000 messages almost instantaneously and it only processed about 2. Obviously this isn't acceptable, but I am unsure how to properly implement some type of queue that will ensure all backlogged messages will get processed.
VS 2008 Preset Messages For Emails?
Jun 21, 2010Previously I asked about sending emails. And now, I have a related question.How to use a preset message in the email ?
Dim strMessage As String = "Hi [USERNAME]..! You have not paid your due amount of Rs. [DUEAMOUNT]. The last date for payment is [LASTDATE]. I want it to be in such a way that, when a button is clicked, all users with pending amount will be selected (from db) and the above preset message is formatted with each user's USERNAME, DUEAMOUNT & LASTDATE, and finally added it to another table in my db.
Presently my idea is to use a SELECT query for getting all the pending users and then loop through each user (record) and add the preset message to a separate table (this table contains all drafted messages which will be then sent to the recipients), by replacing the USERNAME, DUEAMOUNT & LASTDATE using the Replace function.
