• SQL Server Failed to manage image field

  In my simple table in MSDE 2000A, I have an image field. I have enabled 'text in row' using the stored procedure 'sp_tableoption'. How do I get jpeg images in the table, and how do I read them Now, I ask a naive question. Has anybody ever captured an image from the file system, and saved it in SQL 2000 (or MSDE 2000A, which I am using for development) If you don't save image direct to database, how do you manage yor images stored seperate from the database (i.e on the filesystem) For the last two days, I have searched the net and I regret to say I am not making any headway. Lots of stuff on the net have not been very useful. ...Show All

• Software Development for Windows Vista HandleExternalEvent: event filter / correlation

  Hello folks, I am new to WF and I am completely baffled by correlation. What I am trying to do is very simple: I have a State workflow activated by a single event from my local service with a parameter in the event args to do the disambiguation. The HandleExternalEvent activities knows those values at design time, but not at compile time. What I wanted to do initially, and what is my preferred solution, is to derive a new class from HandleExternalEventActivity, add a design-time property that will match the eventarg and filter the events for events matching the property. The problem with this approach is that HandleExternalEventActivity's vi ...Show All

• Visual Studio Team System CA1812 Problem with Resource Files

  Any resource file seems to generate error CA1812 on the auto-generated code.  I have seen this with C# Windows Forms apps, and with C# Web Sites. Is this a false positive   I'm unsure how to make Visual Studio generate code that fxCop is happy with. I've experienced this one myself. This is because the autogenerated code outputs an internal constructor. The fix of course would to be change the autogenerator to output a private constructor (or make the class static) however, this would prevent others from deriving from the class to add functionality. I have reported a bug report on the Mi ...Show All

• Windows Search Technologies How to kill a process that is not even listed in task manager?

  Hi, I'm having a problem to kill a process. For your information, the process is not even listed in the task manager. I would like to delete that particular file, but it seems like there's a process of software currently associated with that file. When i try to rename, move or delete that file, an error came out saying: "Cannot delete filename: It being used by another person of program. Close any programs that might be using the file and try again." For your information later, i am remoting this computer from my site. I don't know wether by restarting the server would solve this problem, as if that the only one thing i wouldnt want to ...Show All

• Software Development for Windows Vista Questions about workflow instantiation/constructor behavior

  I have a sequential workflow, and notice that its constructor is getting called 2 times. Why is this And while I haven't created a state machine workflow (yet), I saw another post that said that these types of workflows had their constructors called 3 times. What's up with this I set a breakpoint in my workflow constructor, but the constructor code executes without hitting the breakpoint. It eventually hits my breakpoint, but not before executing is at least one time without breaking. I'm guessing this is related to (1) above. Why does this happen 1. It appears that the first time we use C ...Show All

• Visual Studio Team System No binaries when built!

  Hi, I have configured a build machine associated with TFS. I successfully created few team build types using my Team Explorer, and the builds run successfully every time. But when I look at the folder where the output binaries should be created, I cannot see any project output files. No executables, no config files, no DLLs. I checked in both the folder and network share (which is configured as part of team build type) But I cannot see the binaries. Any help appreciated. Thanks, Praveen Praveen Can you check Manish's blog and see if this helps. Please check if the platform/configuration that ...Show All

• SQL Server Where are the SSI files saved when saved to the server?

  This is a pretty simple question, but I'm going nuts trying to find the answer. After creating an SSI package, I told it to save to the SQL server... Now where do I go to pull that package up again and make changes and/or execute the package msdb .. sysdtspackages90 is the actual table that stores the package. To edit a package you use Visual Studio (aka BIDS), not SQL Server Management Studio (SSMS). You can work with the original file, or if you don't have that for whatever reason you need to export the package from SSMS, to a file. ...Show All

• Windows Forms is it possible to check "download group" or dll. file version before download

  Hi, I am developing an app. and deploying it with clickOnce. The app. needs 3 extra dll's to work. 2 of the dll's are not changing frequently and their sizes are big ( approximately 2-3 MBs). Even I don't change the version numbers of these dll's they are downloaded with the whole package. Is it the default response for the clickOne API. If so, is it possible to check the remote files' versions before downloading them (i couldn't see any method like "checkFileVersion" in System.Deployment namespace). Thanks very much. Suppose I have 10 DLL's in my application. Whenever any dll is changes i need to give only that dll. I do not want to ...Show All
