I have a windows service written in .NET 2.0 that will run every 5 minutes and executes bunch oracle SQL/PLSQL scripts based on time/validation, it throws the above said error some times against some SQLs, the same SQLs run fine at later point without any error, I have no idea what is going on with the app. I am not sure if this has any thing to do with oracle connection pool as I am properly closing the connections after every SQL execution.
Exception:
System.Exception: Unexpected return code: 1 at System.Data.OracleClient.DBObjectPool.GetObject(Object owningObject, Boolean& isInTransaction) at System.Data.OracleClient.OracleConnectionPoolManager.GetPooledConnection(String encryptedConnectionString,

I am making my project for this semester. I am making "System monitoring Tool" so i have make a GUI and also get the all parameters but one thing missing I have tried to find from different places but not found that is the "continues line" that represents the changing values of CPU usage along time. same like "windows task manager" shows.
View 5 RepliesI haven't been doing a programming for awhile now. But, I was a VB programmer before. I will be creating a tool to log issues encountered by the users of our system. It will be a web based. I'm planning to create it in VB.Net. Any resources that you could share is greatly appreciated. I'm looking for a ready program that I could start with to speed up my programming.

View 3 RepliesI'm tutoring a student in VB 2010 at a local college.i'm trying to explain to the student that he needs to learn the technique or art of knowing how to start coding in VB to accommodate a simple forms program.Is there a name or term that is used to describe the thought process a programmer goes through to convert what the user is expecting into the code that needs to be implemented to accomplish the task?A simple example is a form with a textbox on it and an OK button.When the user clicks the OK button, the program should check the textbox to make sure it is a number and not alphanumeric.The student I am tutoring has a hard time knowing what the first line of code should be to make that kind of test.He has a problem translating what needs to be done into code.I was wondering if anybody knows what that is called and if there is anything written about it.

View 1 RepliesIf i wanted to crop an image in VB.net, how would I go about doing it? I am trying to let the user drag out the box they want (system.drawing.rectangle), and it will automatically remove the edges surrounding the box.
My first problem is primarily the fact that I cannot make the system.drawing.rectangle visible. It is not displaying at all, I am setting its location and height programmatically, but nothing is showing up. I know there is probably something fairly obvious I am missing...but I cannot seem to find it.
My larger issue, however, lies with the cropping itself. I cannot find any crop methods, at all. Is there a hidden one I am missing? Or must I code it myself? How would I go about doing this? It ought to be able to output to a bitmap image object.
i have a data set on the data set many data adapters .i add a data adapter in the data set the designer was automatically delete then lot of error was coming and i search in google and i go this method and i do that right click the data set and "Run Custom tool" on that time the designer will automatically created. but when i do that a error was coming "The custom tool 'MSDataSetGenerator' failed.

View 5 RepliesI have a code written in VB.Net that will run on multiple systems. One of the function of that code is to check for files in some folder each minute.If we run code on different system at different times, it is possible that timer will execute the function to check the files at different times on each system. Is there any way, to make the timer running in each system in sync with each other so that it doesn't matter when the timer start on each system, they all will check for the file at the same time.

I am using VS 2008, Office 2007, and Win7 Home Premium on my system.I have a simple application which should be a breeze to build. All I am attempting to do is pull data from an Access database with four small tables into a data grid on a windows project. Should be simple, set up the data connection, choose a datagrid from the table in the data source view, drag it onto the page and done, right?I can't get it to work. It will all work fine until I attempt to run or debug the project. The data will not show up. The data grid does, but I get this error: A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll
As I said, the project seems to build fine, but it will not pull the data. After the initial build I get the message that Windows will show this page in Compatibility View. Is it something with Win7 Home Premium, or a setting somewhere?
I have a utility that is a simple exe that is not installed compiled with VS2005 and works well. But when I upgraded to VS2008 the utility can no longer locate files in the active system folder.

The timer has to have a value or else the Timer.Stop() call would be throwing the exception. This is a sporadic error and I'm just trying to see if anyone has experienced this before or if anyone has any ideas of what could be causing it. It is occuring in a WinForms application in the event handler for the Elapsed event of the Timer, but it is only occuring sporadically on the users computer. I haven't been able to reproduce the error myself.
