• Architecture Code Generation - MyGeneration, CodeSmith, GAT/GAX or DSL?

  I am looking to generate code based on a database structure. I want to start with a base template and add things I need to it. My goal is to auto generate the boring repetative code so I can focus on the most important areas. I have been looking at CodeSmith and MyGeneration which both have starting point templates that use Enterprise Library but I wanted to see what Microsofts approach was. Is it Guidance Automation or DSL If so does anybody have an example of how to generate DAL classes and entity classes from a database using these tools Fellas, I’m sorry but I insist: aren’t we facing the issue from the solution perspective without considering what the problem actually was The original issue ...Show All

• Visual FoxPro how to shutdown the OS without error

  good day to all. i use my Net monitoring system developed in VFP at my net cafe for almost a year now, and so far it works fine. But there is a little problem that although it don't bothered the user and me but it much better if it does not shows-up. When i shutdown the workstation or restart it from the server, before it will totally close there is sometimes that a VFP error message will pops-up, which will prompt to send the error to MS. How could i prevent such error as if there is still missing in my shutdown code, clear events, clear dll's, etc and etc they've all there already. it seems that the PC can't wait any longer to shutdown. Thanks for any help regarding this matter Madix_t wrote: Good morning to all, i try th ...Show All

• Visual C# how to check if remote user has administrator privileges? (WMI?)

  Hi all, I can't seem to find an answer to this problem. I thought WMI would provide a way to check this, but it seems like it doesn't. I need to be able, from C# (or even from C++), to check, given the username, if that user is an administrator on that computer. It needs to be fast (around 1s at most). Any ideas Thanks in advance, Cosmin. We actually don't have an action to perform. It's just a peeking operation, to do a small check on wether or not a user is admin. Also, we need to be able to check if a given password is the admin's password. Or we could just use WMI to perform an operation that needs admin privileges and leaves nothing behind (like accessing a specific directory or something). ...Show All

• Architecture O/R Mapping and visual controls

  Hi I'm rather new to .Net: what is the best way to link persistent domain objects with data-aware visual controls What I'm trying to do is to use a rich domain model, get an O/R mapping tool/framework (e.g. NHibernate) to take care of persistence but still be able to use Girds and other DB controls. Any help would be greatly appreciated. Andrei. Thanks for the prompt reply Patrik. As I said I'm rather new to .Net so perhaps the answer to my question is quite obvious... Let's say we have a class Person class Person { public String Name; } which has NHibernate mapping and can be loaded / persisted from/to DB. How would you get it displayed in a grid (I mean one obvious and very naive solution would ...Show All

• SQL Server File and Spreadsheet Frustration

  Hi, Two problems / questions I could do with some help on please...... 1). How do you clear a spreadsheet before loading it I am sending a spreadsheet by Email on a regual basis. Each time I run my SSIS package the data is appended to that of the previous run. I need just the contents of this data load to populate the spreadsheet each time. I have tried various methods / techniques for achieveing this so I just need to know the accepted method. Sorry if this is very basic ( as it should be !) but I seem to be missing the point somewhere. 2).

• Smart Device Development Data Applications - Feedback Required

  Many of us develop Smart Devices data applications that require some or most of the following: a. Access to the backend server database from your device application. b. Caching frequently used data within SQL Mobile on devices thus enabling offline scenarios where SQL server connectivity is not available. c. Use RDA, SQL Merge, Web Services or hand-crafted mechanism for synchronizing SQL Mobile with backend SQL Server database. I’m working on certain features that provide out-of-box support for writing offline data applications on devices that can be easily synchronized with the backend server database. Many developers are writing such applications however the current synchronization mechanisms are ei ...Show All

• Windows Forms Retrieving information from a DataBase populated DataGrid

  Hi I've searched and searched for an answer to my question without any luck so I thought I'd post it. I have a MS Access DataBase of the Top 40 singles.

• SQL Server REINDEXING?????

The table is not reindexed and the job running freezes on the EXECUTING state many times is it because of not reindexing the indexes Thanks in advance Jacx When you say it "freezes" what do you mean, where are you seeing it "freeze" Have you run the Profiler to see what is reallly going on How are you updating the table and selecting the records Are you doing: INSERT INTO XXX SELECT ......
