• SQL Server Compact Database Error Code: 0

  I am currently working in VB.NET with SQL Mobile 2005.  I am trying to compact a database, .sdf, using the SqlCeEngine Object compact(connectionstring).  When I use this code to compact a small database, only about 300KB, it returns okay however when I try to compact a larger database, about 9MB, it returns with a SQL Error Code: 0, "The operation completed successfully" however with no compacted database.  The code works however it only seems to work for smaller databases.  Does anyone have any ideas on how to correct this error or tell me why it returns with that type of error.

• Visual C++ "Custom build step" of a project: execution rule ?

  Hi, I am presently using "Visual Studio 2005". I defined a project to generate a DLL X but I needed to do other operations on this DLL X to generate a file Y. So I added a "Custom Build Step" on the project file to generate the Y file. I defined Y as the output file and I even added X as an additional dependency file. I changed the execution order of the Custom Build Step and put it before the "Post Build Event". The problem is that the generation of Y seems to be unpredictable. Sometimes the "Custom Build Step" doesn't run, even if Y is outdated compared to X. And sometimes the "Custom Build Step" always run, even if Y is newer that X... In ...Show All

• Visual Studio Express Editions Installing over VS 2005 Beta 2

  Question 1: What is the correct way to install VS 2005 Standard over VS 2005 Beta 2. Should Beta 2 first be removed and then install the Standard VS or is it ok to install over the Beta 2 version. Question 2: I have been trying to use the different starter kits and the .vsi files are not recognized by VS 2005 Beta2. I am hoping that by installing VS 2005 Standard this will take care of this issue or is there something else I need to do to rectify this problem. I have searched for answers but have not come up with anything that is helpful. Any feedback is appreciated. Thanks John You can't i ...Show All

• Visual Basic How to read and write text files?

  My question is how to read the content of a text file into my programme, and write it into another text file created by the programme. Could anybody tell me the most common method of doing that Thanks in advance!

• Visual Studio Team System Custom Rules Development

  Okay, okay so I know that any rules I write now will need to be re-written with the next release of Visual Studio, however I write (and maintain my own rules and now I'm stuck) .... I've been tasked to write a rule that checks for multiple return statements in methods, this is to help enforce the structured programming principle of methods having single entry/exit points that some of the junior developers consistently ignore. The problem I have is that with introspection I only get the MSIL, which is of course optimised. The optimisation process [is so good that it] actually restructures the code, eliminating all return opCodes exc ...Show All

• Visual Studio Express Editions Database search

  Hi there, I am new to VB Express. I have a project that requires finding 2 fields in a mdb database. The search key is a variant rather than a text box.

• Visual Basic A Pause with a Loop

  Okay...what I want to do seems simple but I've been at it off 'n on for a few days with this & finally decided to post my question. I have a Label I want to flash on & off a few times much like a warning sign. You would think something as easy as: For i as Integer = 0 to 20 Label1.Visible = True Thread.Sleep(500) Label1.Visible = False Next would do it. But it doesn't. I tried throwing a timer in there somewhere but I'm not placing it right. I can get it to run one time (on then off) but that's it. Any suggestions I know this is pretty easy but sometimes easy things can help more then 1 person ...Show All
