How To Stop Application From Receiving A Certain Message
Jan 25, 2012
I believe I have found a solution! I will be continuing testing to make sure it DOES in fact work, but I'm hopeful :) I have detailed how I found the solution in EDIT THREE of the question.
For anyone wishing to know the full background behind my problem and what I have kind of tried as a result of input from this question, see this: [url]
I will be editing this frequently (>3 times a day most weekdays) as I progress my research and situation, so keep checking back if you are interested or have some information or knowledge of my issue :)
Quick Background:
I have this app I have made that can be crashed by changing my screen saver or locking my work station, and in general whenever a WM_WININICHANGE/WM_SETTINGSCHANGE message is sent to it.
If I can consistently crash my app by changing my screensaver, then SOME part of doing that is sending my app SOME kind of message (not necessarily a windows message, I mean message in the most general sense), which in turn is catastrophic to my application. Due to this, I am trying to find a way to block whatever message is causing my problem from being processed by my application. I am aware this isn't the best way to go about a solution, so you don't need to tell me. Look at the backgroung info or ask why if that bothers you (there is a good reason).
I am currently developing an SMS application to read and receive SMS. I run the application and tried to send an SMS and the application indicates that the message is successfully sent. However the recipient did not receive the SMS. I am using Sony Ericsson T610 btw.

I am working on a data entry type form and I want the enter key to move focus to the next text box. I've got that working great except that the focus is moving to the label that is, in sequence, between the text boxes.
I am working on a client/server application. Everything seems to go well for a while (a few hrs, a few mins its kind of random) then suddenly clients stop receiving data. maybe 1 or two, or all of them. in the end I end up having to restart the server piece to resolve it, but I am trying to understand why its doing this. I've added try catches around the send piece, but it doesnt error out. When the app fires, the listener is started on its own thread. When a new connection is made, that connection is passed to a class that handles all of my connection data(send/receive, responding to commands, etc). The class is started in its own thread, so each connection is running in its own memory space. This issue seems to happen with 1 client connected, or 20, it doesn't really seem to matter.
This causes other issues, like a customer who thinks he is disconnected, will shut down his app, which is supposed to send a command to close the connection on the server side which it does not., so now I have several "closed" connections still open on the server, which is obviously also bad. Another thing I dont get is that it worked fine when I was developing the pieces on my dev box, so I dont get why I have all of these "timeout" issues now. (I put that in quotes, because the timeout period is the default of 10 mins, and I xmit data, at LEAST every minute when the server pushes data updates to all clients)
Here is some of the relevant code vb 'Command Object, this holds all of the command information being passed back and forth to tell the server what to do, and as well as hold the response. 'The strCMD is the command, strParms is the parameters of the command, obj is ANY object I want to send along with this information <Serializable()> Public Structure CommandData Public strCMD As String [Code] .....
I have a custom UserControl that contains just one TextBox. When I set the control to Enabled = False, the TextBox is disabled but the control is not (control still fires the Enter event).
How do I ensure that the UserControl will not receive focus?My Enabled Property Looks like this:
Private _Enabled As Boolean = True Public Shadows Property Enabled As Boolean Get Return _Enabled End Get
I have an Vb.net application made by a third party , that I need to control using outside resources from a simulated environment and must not interact with the desktop. To simulate inputs that a user would normally input from a special screen with specific keys around it, I've built a test control library to control it and send the form image to a .bmp. The form cannot be visible and showed in taskbar , the bmp output will be displayed by the simulated environment.Using PostMessage and sendKeys work well as long as I don't but ShowInTaskbar = False for the main form. After many read & testing, I have learned enough to try what seems to be the only thing that would work. I've created a form that I setparent using HWND_MESSAGE parameter, this should create a Message-Only Windows, that are supposed to received postMessage, and subclass it's events.msdn.
I can't seem to get it to work, and I was hoping someone could tell me what I'm doing wrong.I have been testing several different ways found through out the web about .net , and short of going into message thread peek and feed(maybe(may be)my last hope), they all seem to work until I take the forms out of the taskbar.[code]
I am developing a chat application in asp.net using vb.net. In this, if a user receives a new message from other users then I want to play a sound to let him know that he received a message. I wanted to play some .wav files.
In need vb6 program Works with GPS. I want this program to works with GSM Modem, which is receiving a SMS Inside the message the longitude and latitude. I want the program view the coordinates on the map in [URL].
I am taking my first quarter of programming and am having a VERY difficult time understanding jagged arrays. At the moment I am working on a project that is using two two dimensional jagged arrays
If IsNothing(g_decChargesArray(g_intActivePatientNumb er)) Then numVisits = 0 Dim decTemp(g_intActivePatientNumber) As Decimal[code].....
The line in bold is the only way I can think of to pass the amount of decCharges into the array g_decChargesArray.
I have written a very simple Windows Forms App. which copies files from my hard drive to my USB flash drive.The app. works ok, but while it is running (copying files) the title bar displays (not responding).I have an idea this is due to the time it takes to do a large copy.
I have two questions:First, I want to add a progress bar, as a visual indication as to how much is left to copy, but I don't know how write the code required for the progress bar when copying say: C:*.* (including all sub-directories)
Second, to stop the (not responding) message being displayed in the title bar. Would I need to run the copy as a background process? If so, how?
i am working on a project. Part of the project requires me to receive SMSes through VB.net windows application, the following below are codes i have done up till now. I am using a modem to receive the SMS and i am able to connect to it through using of serial port, and also a textbox to display the received SMS but when a SMS is received through my modem but it is not displayed on the textbox, can anyone help me check what is wrong with my codes?
I am doing a project on sending and receiving sms. I am doing this using the visual studios 2005 ans SQL Server Database to store the send or received sms. I have search on sms in the internet but the problem is that it is using C# as I am using the vb.net language. Even though some of the research that i came across is in vb.net but the application did not work.
In my research, the sending and receiving of sms application uses sms gateway, AT command. But I am not sure which one to use becoz I am doing this application for my project. Hope for any recommendation on which one to use either the sms gateway or AT command or any other device. My lecturer said that my project is most likely like the M2U Mozat. Not only that I am doing the sms but also the email. The email part is done by my partner but the problem is that he creates the email using the SMTP server. How can using a SMTP server to create sms? It is because the part that I am doing which is the sms and the email to combine together.
there is a complex situation wherein, I have to pass a string data to a .exe application and this .exe application would process the string and respond back to my php data. I prefer not to use a TCP/IP connection.
I'm writting what I thought would be a fairly simple TAPI program in VB.Net 2008 SP1 using the TAPI3Lib.dll. It is supposed to dial out a number and once connected play a wav file then wait for digit input. I got through the dialing but it seems I never get the CS_CONNECTED event letting me know the line was picked up. All I get is CS_INPROGRESS then the call is placed and a CS_DISSCONNECTED if I call the call.disconnect method.
I've double checked my registering for events and my event filter and they both check out (otherwise I wouldn't get the two call states I do get). Is there anything else I'm missing or is this normal? I'm calling out with a Conexant HDA D330 MDC V.92 Modem. The call is correctly placed, my phone rings and I answer it. The call state never changes to connected. If I hang up my phone you hear me hang up through the modem and you then hear a dial tone since the modem in the computer hasn't hung up.
I am trying to make an application with a start button and a stop button on a stop watch program. These are the codes I am using but my seconds on the stop watch don't start.
Public Form Dim intSecond As Integer = 0 Form 1 Private Dim intSecond As Integer = 0 intSecond +=1
[Code]...
After I write my code and try to run the program, the seconds will not start,
I need to write an application for receiving data (ascii characters) from microcontroller through the serial port in three separate parts. I've created three RichTextBoxes, but I do not know which commands I need to type. In first textbox I need to receive one byte... next six bytes need to be placed in second text box, and finally last seven bytes need to be placed in third textbox.
When i click on my installed VB.net application icon on the desktop,i receive the message : 'Application failed ti initialize property ox700000000000000 ..... click ok to terminate application'.
I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load tmrnote.Start() Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
I have recently created an application where a lot of data is loaded into objects when the application starts up, and other data as it is required. For example if the user requests the catalogue page then it will load all the top level category data into objects of type Category. This will then stay there to be used by other users (who will therefore not have to load this data into objects) and can be altered by admin if they happen to login during the same application instance. I know this is not the most efficient solution, as pointed out below, but it works and the page load, at the moment, is not too long. It is very quick if most of the required data is already loaded into objects. It is also tailored to the business' needs - unlike other techniques such as Linq-to-SQL.
This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.
I have a windows forms application that has no form and it runs in the background. It using a webbrowser control to get information off the internet.The program is that when I add the event handler:webbrowser.documentcompleted the program just shuts down. If i put a message box after the event handler then it works just fine because the webrowser has time to load the document. How can I do some like console.readkey that you would do in a console application?
I have an application in wich I have included a timer wich close automatically the application when no activity is detected.My problem is that when I make 'some activity' like accesing something, I do not know how can I reset the timer to 0.
I have something to ask again.. I develop a program that will send bulk messages but the problem is that when I load at least 1000 emails then I want to stop the application I cannot stop it. Is there any way to stop this application without closing the form? So that i can save the file on my listview? Here is my code upon send bulk emails. [code]...
I have created a small program but the code is quite big.
I have a start button that when clicked it runs the script in a private sub called start(), when it gets the the ens it calls the start() again to loop it and restart the script.
I have added a stop button, but how do i make the script stop ?
