• .NET Development OraclePermission

  I keep having this problem when I tried to run a program from another machine. {"Request for the permission of type 'System.Data.OracleClient.OraclePermission, System.Data.OracleClient, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."} Any comments Hi My first .NET project was using Mainframe DB2 database with Web Services and .Net 2.0 which lasted between 2006-2007. This year, I am starting on a .NET project (not incorporating web services) using Oracle database. I noticed that as I started building my test application to connect to Oracle and retrieve data from Data Provider classes and Data Sources, things started slowing down and eventually I started gett ...Show All

• Windows Forms Identifying COM components in a deployment project

  Hi, I am developing a deployment project in VS2005 in which there are several COM components also. I know the Register property of each COM component is to be set to vsdrfCOM but the problem is that how can i identify which file is a COM component and which one is not Any help,suggestion,link would be highly appreciated. Regards, Wasif Ehsan. The setup project does a pretty good job detecting these for you. If it's a managed assembly, it will have vsdraCOM as a value to the Register property. It also has the grey box icon. If it's otherwise, it will have vsdrfCOM as a value. It also has the file/document icon. ...Show All

• Windows Forms How to access controls on another form

  Hi, I need to access a control that is on a separate form, I have 2 forms, my main form and the details form,so my main form calls my details form, but from my details form I need to access some of the information on the datagrid that is on the main form, I was thinking on using properties but there are too many fields that I need to access, so I was wondering if there is another way. Thanks. When wanting to have one form make changes to another or it’s controls, it is possible to declare the target control(s) as public members instead of private ones... this however is generally considered bad practice as it violates the encapsulation concept of object oriented programming and instead the common suggesti ...Show All

• Visual Studio Team System Can i force developers to add comments at check-in ?

  I need developers to add comments at check-in time - probably i will need a custom check-in policy (how do i do that ). I know i can force developers to asociate work items at check-in but in our case it would be much easier if i could force them to add only comments ! 10x Glad this topic was of such use - actually about step 3 - the name of the key should be the name of the dll (without extension) and the value is the absolute path to the dll. The rest should go smooth - if you are interested i can post my solution (that was built after this thread); there's a setup project there too, so that you don't have to mess around with the registry. Best of luck ! eraniopub wrote: ok i solve the problem an ...Show All

• SQL Server SSIS advantages

  This may be too general a question but I'm going to ask it anyway. I'm moving data from a source DB (say A) to a target DB (say B). On A I need to join 3 tables and, after some lookups etc., I need to populate several tables in B. Inserting into B's tables involves sequential operations because in many cases I have to get back the value of an Identity column to use as in input value in a another table 'downstream'. Additionally, the tables in B are populated as a group i.e. if the insert on any one fails the entire group's insertion needs to be rolled back. I set up a set of stored procedures to do this. The master Stored Proc opens a read-only cursor and for each row of the cursor executes the other SPs in proper sequence. Some of t ...Show All

• Visual Basic New project-needed help with many features

  I just started using vb 2005 express for a school project, so I'm quite unfamiliar with it. I would like to do some advanced "add" features, which I need help with: 1. Not be able to proceed to the next form unless all fields are filled in. Get a warning message when pressing the "confirm" button. 2.Allow more then 1 radio-button to be pressed in the same form. 3. Generate random pictures (validation pictures) each time I open the add form. You have probably seen these things before on website registrations (write down the code you see in the picture).  4. Each picture should have a code, which must be written in the field below to be able to proceed to the next form. Once again, the same feature ...Show All

• .NET Development How to create a class model for using XmlSerializer.Deserialize() on a preset schema?

  I am attempting to create a class model which will consume the following XML: (note: there are different types repeated under the root node) <TypeA> <TypeB id=”1” /> <TypeB id=”2” /> <TypeC name=”1” /> <TypeC name=”2” /> </TypeA> Unfortunately the XML is rigid (it's a pre-defined standard). Is it possible to create a class structure that will model this using XmlSerializer.Deserialize() Thanks, Jacob Pitts Morgan is correct: XmlSerialzier is schema-driven serializer, if you can create a schema that describes all your xml instances, then you can use xsd.exe to generate classes (from ...Show All

• SQL Server How to use a Table Variable

  Hi all, I have a table which holds a list of users names & the table assigned to each, e.g. - John Smith - Table1 - bob Jones - Table2 etc I have a store procedure which calls the information from the user's table based on the username. Something like this: Select * from @UserTable So if user is John Smith then @UserTable = Table1. Though the @ function does not work for referencing a table. Is there a workaround to this Rgds & thanks. Hi, Couldn't you federate the username table and the multiple user tables into only one table and use a stored procedure That would save you a lot of trouble. i.e. where you have: Table_users User_Name, value_1, Value_2, Value_3 Value ...Show All

• Visual C# Canceling a BackgroundWorker

  Hello everybody. I am still a newbie and I did not understand much from the articles I was able to find about canceling a BackgroundWorker. Anyway. I have a form and a button on it.

• Visual Studio 2008 (Pre-release) Suitable inheritance?

  Hello everybody! Just wanted to get your input on a decision I have to make.. I want to design a menu where the items flyes out in a quarter-circle when clicked. The question is, what is most suitable to inherit from Button, Panel or maybe Menu The problem with Panel is that it does not have the Click-behaviour of the button. The problem with the Button is that it does not have support for multiple Children. Menu would be ideal, but how customizable is the Menu, I have not seen any examples of this. edit. hmm, just realised that perhaps the HeaderedContentControl would be the best choice Thanks for your input! /Simon ...Show All
