View 14 RepliesI am trying to send and receive data using the SerialPort component. I am sending data to an Texas Instruments MSP430 which simply echos the sent character. I wanted my VB solution to read characters from a file, send a single character, and wait until the echoed character is received before sending another.
I have been fairly successful thus far but I have run into a little catch. When I attempt to send large files (323505+ characters) my MSP430 just hangs there and will not receive any more characters. My VB app return to VS '08 with timeout errors (timeout set to 1 minute).
I wanted to post my VB code here to see if the problem is from my VB app. I will be posting this problem on the IT usergroup to sort out anything on the MCU end. Here is the pastbin of the data write and the data receive subs:[URl]..

I am using the System.Net.Mail namespace to create and send email messages. Everything was working fine until a couple of QC members of our team noticed something strange.
If they send emails from within my application and then leave the application open for a while (perhaps working on other tasks on the PC), when they try and activate my application again, it appears to be hung. The CPU is not pegged and everything appears to be normal in the task manager. We narrowed it down and it appears that this issue only manifests itself when MS Outlook is also opened and connected to a server.
I was playing around with process monitor, but nothing I saw was really glaring. I actually started deleting some threads on the PC and eventually my application became usable again.

View 2 RepliesHere's the scenario, winforms application, monitoring via Task Manager Processes Tab.On initial launch spins up to ~61,000K (initial data grid and data loads)If I minimize the application, not touching or doing anything the Mem usage drops to 1,380K.When I restore the application is spins back up to only 5.8K
So my question is, does the minimize send some internal message to clean up resources since the application in question is not in focus?The first app I noticed this in happens to be VB.NET, but I've observed the same behavior in my main C# winform applications.
I'm working on an app at the moment that requires a bunch of apps not made by me to run. The user has to be able to put some inputs into these other apps, but after that I'd like to have a button they can push on my app that minimizes all of these other apps under one icon I can choose. When the icon is clicked, these other apps would jump back up again.

I had created a media player using directx. It works perfectly even with resizing the form but I having problem when I minimize it. I use panel as the owner of the video and after I minimize and change it to normal state, the panel goes blank but the sound goes on. Then I get an error in application notification by VB2008. There might be something to do with the graphics where I dint handle it when I minimize it.
View 3 Replies1) Is it possible to allow a vb 2008 program to run at computer startup. Meaning, one the computer is turned on, it will load up with all the other startup programs so that it is ready to use.
2) I also would like to know if it is possible to have the program minimize down to the tray where all start up programs usually appear. So that instead of it cluttering up the task bar it will be in the tray and when they clcik or double click it, it will open back up.
I have this rather annoying problem when printing in VB.NET. I use the PrintDocument object and after it has done its job, the form gets minimized to the taskbar. I tried to force the focus on the form but to no avail. I was just wondering if someone else has encountered this problem and maybe has a solution for it?
