View 7 RepliesRetrieving Processor Current Speed Makes Program Run Slow?
Jun 5, 2012I am trying to create a program in Visual Basic which will measure the performance of the CPU with every core, one at a time. In this program, I decided to place a couple of text boxes that display the processor speed and the actual processor speed. I need to get the actual processor speed to update and I have tried doing this already using a timer set to tick every second. However, when I load the program it runs really slowly and prevents me form doing anything within the program, including trying to close it down, and all it does is updates the text box every second. I have looked in task manager to find out how much CPU the program is using and it shows that my program is using 0 - 3% CPU.
Here is the code currently use

I've linked a variable implying the progress of the for loop with the progress bar, but it seems that when I run the program, the progress bar does not update itself. The bar itself has only value 0-100 as input (as stated in the document) and I've tested it without using the for loop, and it works.
View 2 RepliesHang/deadlock In MSJET40.dll?
Jan 17, 2012I have a VB.NET GUI (VS2005) that calls into a VB6 DLL to query MSAccess 2003 databases using DAO 3.6. Yes, I know this is not an ideal scenario, but that's the way the current application is set up. Component Checker shows MDAC 2.8 SP1 is installed. This application usually runs for a long time on our customer's Windows XP SP3 system with no issues. Occasionally (read: after 11 minutes or 11 hours or days), we experience a hang in the application, such that it needs to be ended with task manager and restarted. According to crash dumps and one lucky capture within the debugger, all threads are waiting on objects/critical sections within ntdll.dll. My specific thread gets stuck there and comes from MSJet40.dll. In the crash dumps, most threads are stuck in NTWaitForSingleObject, RtlEnterCriticalSection, etc.
I've been troubleshooting this intermittent issue for months and am convinced this is a bug in MSJet40.dll. The version of the DLL is 4.0.9511 and I see there is a hotfix for 4.0.9514 on XP SP3 outlined in: =[URL] I would like to get this hotfix to see if it fixes the issue and speak with MS if it doesn't. I have crash dumps and procmon traces of these events. This sounds very similar to the dreaded "Jet Bug" that shows up on a Google, supposedly fixed for Windows 2003 Server SP1, but I see no mention of it on Windows XP SP3.
VS 2008 SerialPort Hang-up?
Jun 23, 2010I 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]..
