Message Pump And Console App?
Oct 15, 2009
I've written a console application (no GUI elements at all) in VB 2005 that makes an SSH call to a UNIX server and runs a script there to do some compiling. I need my application to wait until the other script completes as I need the return code. I'm using a function that pools the open channel to retrieve the results. Everything is working except after waiting 60 seconds I get an ContextSwitchDeadLock error. The error message says its caused by my not having a message pump to handle messages and that could cause problems. I didn't know console applications had message pumps so my question is why and how do I get past this. I saw one suggestion online to disable this message but as I don't really understand all this is reluctant to do this so how can I solve this?

I have an application I am creating that displays pump information based on customers in a database. I am using VB2008 .NET3.5.I have a combobox that has a selection for a unit of measure. What I want to happen is when that is changes the labels that have a unit of measure change to reflect the change. There are 15 labels total that need to be changed and all there names are the only ones in the project that start with a X if that helps at all.
I would like to avoid creating a bunch of labels and changing the visible property and just change the text value of each one. I have just started learning VB.NET

I was thinking of adding a simple bandwidth monitor to a console application and I was wondering if it would be possible to keep a line in the console window visible at all times. I could set something up manually to pass new console output into a method that would get the contents of the console, clear the console, add the bandwidth data on the first row, then rewrite each line of previous information back to the console, etc.. but that seems like a really hacky way to go about it, and I'd be limited to the amount of rows visible at once in the console window (no scrolling).

I have a console application I'm using to run scheduled jobs through windows scheduler. All the communication to/from the application is in email, event logging, database logs. Is there any way I can suppress the console window from coming up?

I am currently working on an application, where I am using a console application, that will set up the application prior to the main form is run. This is no problem I've got that all working perfectly, the only problem I have is that the console is showing while the application is running, I was wondering whether anyone knows any way in which I would be able to hide the console before it gets shown to the user.

I am trying to send/print/write all possible ASCII codes (0-255) to another console-window application. From my application I would enter the name of the "receiving" application and the comma seperated hex values that should be sent/print/written to it. I have used AppActivate to select the "receiving" application and then have used sendInput and send.sendkeys to attempt to send the desired ASCII value. However, these appear to have limitations on values greater than 127. I need to be able to send all 255 values.

How do I get the console from closing immediatley upon opening in a Console Application program? I have all of the code written but when I run the program it pops up the console window and then immediatley exits so I am unable to read what is in the window to see if my program is operating correctly. This is the first time I've ever used a console window so I don't know where in the code I would need to put "whatever it is" I might need to put to keep the window open until closed by the user.

It sounds confusing but it's not really. What I need is basically a way to emulate the console style text, without using a console. What I'm really doing is trying to do a matrix effect on my form background, by drawing symbols and moving them, alternating their colors (see this video for what I mean).
Is there a way to do this effectively with a timer and a draw event, with the timer calling the draw event and changing the intervals?

create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim name As String
Dim icn As String
Dim message As String

I am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

I am sending a DDE message to a client using System.Text.Encoding.ASCII.GetBytes(item) . However, before the message is actually sent, I would like to get the message coded where if the item="Ask" then item=Ask (string variable) and so on. The code is:
Protected Overrides Function OnRequest(ByVal conversation As DdeConversation, ByVal item As String, ByVal format As Integer) As RequestResult
' Return data to the client only if the format is CF_TEXT

I am needing to pass options to a windows mobile console app so I can pass variables.I have that working fine, but have found out that my options need to be a little more descriptive as I will probably have 20+ in the end. I am wanting for example myapp.exe --username bob --password myp@ssword --domain ads.microsoft.com --SSID wirelessnetwork --authentation peap --securitymode wpa1 etc Right now my code just goes by charcter length that limits me to the same length of option. I want to have longer descriptive options but need a way to allow longer option lengths.

I want it to check for my DLL in the same directory. If it's not there, the application should exit gracefully.I thought this code would work but it still crashes without the DLL. Although it will not crash if I comment out everything after the IF statement.

I have to convert a C# project to VB.NET and VBA. It's a console app that uses the Microsoft Office API (Microsoft.Office.Interop.*).
C# -> VB.NET: .NET Reflector is a good tool for this, except that it doesn't preserve source code comments. Is there a way to do this?.NET -> VBA: is there an automated tool to do this conversion? It would need to be a client side tool (because the code is proprietary).

I really want to do this the proper way, it's just that I've been doing it the wrong way for so long, I can't seem to get past it.
in a console app if I start a timer or kick off a thread or bgw, the sub main runs right on thru and the app finishes and closes.
i need the sub main to just hold position until some event is raised then handle the event and come back to sub main or end depending if the event that was raised told us to end or not.
what I would normally use is this:
Do While KeepLooping
Wait(5D)
CheckTimedEvent()
Loop
