• .NET Development Dynamic SQL generation is not supported against multiple base tables

  I m coding with VB.Net. I have a datagrid on my form with a dataset as its datasource. The dataset contains rows from a joined two tables: Feature table and Price table. Feature table contains the customers'features. It has the ID of the features, the date the feature was added, the expiry date, the employee who added it.... The Price table is a look up table that contains the ID,price, Code, description and name of each feature. So my SQLquery is: SelectFeature_ID,Feature_DateEfect,Feature_DateExpiry,Feature_Employe, Price_Name, Price_Code, Price_Name... The reason why I use that joined query is that I need to display all the columns on my ...Show All

• Visual Studio Express Editions List Box Delete Question

  I have a check book reconciler program. The user inputed values for Checks, Deposits and Fees are displayed in their respective list boxes. Also as items are added - I have updating the checkbook balance accordingly. My question is - I want to allow the user the option of deleting any entry in any list box. Prior to deleting the entry I need to know the decimal value so that the checkbook balance can be adjusted accordingly. For example if my lboxDeposit has 5 entries and lboxCheck has 10 entries, maybe the user wants to select the 2nd item in lboxDeposit or the 2nd item in lboxCheck. How do I get the value (not the index) prior to deleti ...Show All

• SQL Server ErrorCode and ErrorColumn in Excel Destination

  I am exporting records with errors to Excel using the Excel Destination tool. The ErrorColumn is a numeric. How do I find out which column it is While it's fairly easy to add an ErrorDescription column on top of the ErrorCode, it's NOT so easy to add an ErrorColumnName on top of the ErrorColumn numeric ID value, because of all the ifs ands and buts that determine whether the column name is readily available or not. (For example, did the preceding component have synchronous or asynchronous outputs, and so forth.) You can run your error output through a Script Component and try looping through the columns in i ...Show All

• Windows Forms Pass around object references or IDs?

  Say I have a TreeNode that represents a Customer object. It displays the customer's name, and when it's activated a form opens to edit that customer. In order for the form to know what customer to edit, the tree node has to keep some kind of reference to the customer object that it represents, and pass some information to the form to indicate the customer to edit. As I see it, there are two ways for the tree node to keep the reference to the customer: Store the actual customer obejct in the tree-node's tag Store the customer's ID in the tree-node tag. (The ID is an int, long, guid or whatever) And two ways for the customer-ed ...Show All

• Visual Studio Team System Team Suite 2005 RC - Can't run unit tests when web project is in solution

  If I create a solution with only a class library, unit tests run as expected. If I add a web project to the solution in addition to the class library, unit tests will not run and I get an error message like this: "Operation is invalid for the current state of the object." Removing the web project from the solution doesn't immediately resolve the problem but by cleaning, rebuilding, and opening the solution from scratch unit tests will work again with only the class library. Any suggestions We have not experienced this problem since moving to the final VS2005 Team Suite. It appears to be corrected in the shi ...Show All
