• SQL Server Parsing transaction log

  I want to write a program that works like SQL log rescue or ApexLog or one of the many other programs that are too expensive to buy. I would like to ask the question, does anyone know how the format of the log works Or how can I parse the binary file into readable text Can I contact Microsoft about this Please do not reply and tell me to buck up and buy one of the 3rd party software packages available. You can start by checking out DBCC LOG -- it's undocumented, but do a Google search and you'll be able to find the inputs and outputs.   Personally, I'd still go for the 3rd party solution -- Log Rescue is only a few hundred dollars.  I don't know how you value your hourly tim ...Show All

• Windows Forms Windows Form Designer bug in causing an event handler to disappear, C# example

  I am not sure whether the following scenario is a bug in the Windows Form Designer or some failing in my own implementation, but I hope someone can look at this before I submit it as a bug. The scenario is: I create a CLR class library project. I add a component class, let's call it CsCmpA. I add two virtual events to the component class, both of type System.EventHandler, let's call them EventA and EventI. I create backing variables for both events, let's call them bEventA and bEventI respectively, and use the long form of specifying the events. I also override the Equals and GetHashCode virtual functions. In the same assembly I add a UserControl. The user control, let's call it CsUserU, has a property, let's call it PropertyU, w ...Show All

• Visual Studio VSIP - Path to selected folder

  I am having some problems figuring out how to get a Path to a selected Folder. By path I mean Full Path. Or at least something that would get me there. Currently my code looks like this ( in the Exec method, so i know my item is selected, and my command fired ). I am aware that ON the UIHeirachyItem I have no path, however, I should be able to navigate to the project Item, and get the path from there, and attach my items name to it. ( Perhaps there is a better more reliable way ) In any case, my projectItem is always returning null, and in any case, i have no guarentee i am acutally accessing the project item, so I would appreciate any help. Thanks. try { UIHierarchyItem fld = firstSelectedUIHierarchyItem(); // _applicationObj ...Show All

• .NET Development Access 2003 vs VB 2005

  I am currently develop a software that reads of many different databases. I am trying to create database in ms access 2003 that hold the nessary information from different databases. I have foxpro, oracle, csv. Some of them will need some data massaging to show up correctly in ms access. I will have to import into ms access from the different sources. I need some guidelines to approach this problem. My thought was to create a vb 2005 data massage module, transfer the data into ms access. my concern is the performance. ms access seems to import the foxpro table much faster that tableadapter but i havent found any VBA code that data massage it. also i need to update the ms access database every day.

• SQL Server XML Task inside Foreach Container, fails all iterations after first failure

  I am looping through xml files and validating them with the XML Task. On sucess I want to perform task 2, on failure I want to perform task 3. When one file fails to validate all subsequent tasks fail. I have also tried putting the result in a variable instead of using the success constraint. I get the same result, the variable keeps the failed value after the first file fails. Any advise is greatly appreciated. That sounds like a serious bug with the XML Task.
