    Hello all – I am experiencing an extremely odd bug with an application I’ve created and I cannot figure out why it is doing this… The application generates weekly reporting stats as Excel files by copying the previous week’s file with a new name (ex: 04-06-2009.xls – Monday of the week the stats will be generated for), clears the data within the workbook and inserts the selected week’s stats that are pulled from raw data extracts. This portion of the form contains a date/time picker with the initial value of March 18, 2009, a label, a text box and a button to b

    I know that this should be rather simple but i seem to be missing a step to get it to work. and have been unable to find a solution on the net. The aim is that I click on the open button to find and open an unknown workbook that contains the data that I need to imput into my current workbook, once the unknown workbook is opened it should automatically select my range (number of columns known, but number of rows unknown- the number of rows needed to be copied will change each time the unknown workbook is opened).

    Hello,I’m working on a search form. I have 3 combo boxes and I want to find combinations on a query to later show it in a report. Perhaps this is too complicated but I don’t know how else to do it. I thought this code worked at first, but then a realized it wasn’t really working. I know something is up with the if statements but I don’t know how to fix it.

    Hi, I’m working on an Access 2007 database. I’m trying to build a search form that opens up your search on a query. I was working before, but I feel like i change something and now, it doesn’t give me what I’m asking for. I have three fields on the form (companycell, companyflux, companyribbon). I don’t know how to incorporate the value from companycell to the field on the query.

    Hi all, I am working on vb.net web application and Often getting the following error. But even with the same inputs it is not reproducable. In most of the cases its executing successfully and in some rare (unknown) cases only its failing. The interesting point is; I just noted one set of the inputs caused the problem and tried to reproduce the same problem but not able to reproduce the error. One time error came

    multithreading thread-safety nullreferenceexception basic blitzmax
    First thing to say: I program in a relatively unknown language: Blitzmax, which is a object oriented Basic dialect.My problem is the following: I wrote a debugmanager which runs in an own thread. So from every position in the program (it will be a game) you can add debug- or errormessages to the manager’s queue. In its own thread, it will fetch the messages from the queue and process them by writing them into a file and (if the message has the current chosen Debuglevel, Debugcategory and outputcategory, which are just enums) write it to the console.Now I tested the program on three systems: My desktop PC which has Windows 8 as OS, my own laptop which has Windows 7 and the laptop of a friend which also has windows 7. On my PC and my friend’s laptop everything is fine. But on my own laptop I get, nearly everytime, an “EXCEPTION_ACCESS_VIOLATION” Error while the manager is processing the messages. Sometimes the program just runs fine, but most of the time it breaks down with this error. Even in debugmode no line or stacktrace is shown which made it very hard to debug.I broke all needed classes down to a minimum of attributes and functionality to make it easier to find the problem. Now the queue is just a list (which is natively build in in Blitzmax) and the message just has one attribute which is a string. Also the debugmanager only writes the message into the console without passing it to the process method which would wri
